The invention of Daflorn

The new discovery of Daflorn is isolation of a probiotic association of lactic acid microorganisms from spring water in the wild nature in Bulgaria – a spring in the Balkan mountains.

The probiotic association contains 8 wild all natural strains of 4 species lactic acid bacteria of Lactobacillus bulgaricus, Lactobacillus helveticus, Lactobacillus lactis and Streptococcus thermophilus. The original strains of the probiotic association live in spring water.

Isolation of probiotic strains from a natural water source raises the question of revision of the popular belief in the scientific community, that the probiotic lactic acid bacteria can be isolated only from dairy products, plants, animals and man. Capture of probiotic microorganisms from spring water happens for the first time in the world, so we can talk about a scientific discovery. That discovery gives a great advantage and sky-rocks Daflorn to an indisputable leader in innovation in the production of probiotic products.

We managed to ferment typically pasteurized milk from the commercial network with spring water.

This is a unique method for capturing of wild all natural probiotic microorganisms from spring water. The lactic acid microorganisms in the probiotic association live and develop in natural aquatic environment in the constantly changing climatic conditions in the wild.

Our new wild probiotic microorganisms are registered under the Budapest Treaty on the International Recognition of deposit of microorganisms for the Purposes of Patent Procedure in the Czech bank for microorganisms.

  • strain Lactobacillus delbrueckii subsp. bulgaricus DWT1, registered at CCM under No. 7992
  • strain Lactobacillus helveticus DWT2, registered at CCM under No. 7993
  • strain Lactobacillus delbrueckii subsp. lactis DWT3, registered at CCM under No. 7994
  • strain Streptococcus thermophilus DWT4 registered at CCM under Number 7992
  • strain Streptococcus thermophilus DWT5 registered at CCM under Number 7993
  • strain Streptococcus thermophilus DWT6 registered at CCM under Number 7994
  • strain Streptococcus thermophilus DWT7 registered at CCM under Number 7995
  • strain Streptococcus thermophilus DWT8 registered at CCM under Number 7996

The microorganisms in the probiotic association, isolated from spring water, are unique and differ from the probiotic microorganisms, found in the plants (grass, flowers, plants and algae) in and around the water.

The new probiotic microorganisms, method of obtaining the products and the products are subject to patent protection of Daflorn, application number 111161/07.03.2012 in Bulgaria and Patent number US 9,131,708, B2 in Patent office in USA..

Daflorn Ltd uses these all natural probiotic strains for the production of unique probiotic products. During the biotechnological production mode the lactic acid microorganisms are naturally enveloped with the amino acids, fatty acids, simple sugars, micro elements, minerals and vitamins of milk, obtained as a result of fermentation. During the biotechnological production as approaching the fermentation process as close as possible to the natural one, Daflorn managed to create the most ancient and at the same time the most modern generation all natural probiotics.

Until now there are 4 known generations probiotics in the probiotic production:

  1. 1st Generation – non coated probiotics
  2. 2nd Generation – enteric-coated probiotics
  3. 3rd Generation – micro ecapsulated probiotics
  4. 4th Generation – dual coated probiotics – ph dependent release system , moisture, temperature and pressure protection

All of the above generations are scientifically manipulated by man.

X generation of Daflorn is the oldest and at the same time the most modern generation of all natural probiotics

Advantage of the new generation of Daflorn

We put the nature in the science, in the biotechnology and during the biotechnological mode of production of Daflorn the probiotic microorganisms naturally “envelope” themselves with natural coat, consisting of lactic amino acids, fats, vitamins and minerals, which preserves them alive at a room temperature (20° -24° C) for years.

Despite the high sensitivity of Lactobacillus bulgaricus, Lactobacillus helveticus, Lactobacillus lactis and less of Streptococcus thermophilus to lyophilization (freeze drying at -45° C under vacuum for 48 hours) the probiotic microorganisms in the association survive during this way of freeze-drying and stay alive in the obtained dry probiotic products. The probiotic bacteria from the association survive after rehydration when they pass through the gastrointestinal tract. The study was conducted under extreme conditions – pH 2.5 for 2 hours and after that at pH 8 for 5 hours. The wild probiotic strains have excellent viability and can optimally colonize the intestines. Their maximum activity of probiotic bacteria manifests there and that ensures their high efficiency.

Survival and stability of the probiotic bacteria from the association is due to the natural coat with which they are enveloped during the biotechnological process as well as to their natural water origin. In nature they have adapted to the changing climatic conditions and have acquired very high viability. That natural coat and the water origin of the probiotic microorganisms ensure them the stability and maximum bioavailability.

In the probiotic association the strains of lactic acid microorganisms multiply and develop together which is a new step in science. Until now it was known that Lactobacillus bulgaricus develops only together with Streptococcus thermophilus. In the new X generation found by Daflorn the 8 strains of 4 types lactic acid microorganisms Lactobacillus bulgaricus, Lactobacillus lactis, Lactobacillus helveticus and Streptococcus thermophilus live and multiply together. This enables the obtaining of products, extremely rich in live all natural probiotic microorganisms, and thus they are extremely valuable for healthful nutrition of man.

Lactobacillus bulgaricus and Lactobacillus helveticus are probiotic microorganisms that carry out homo-fermentation. During that fermentation pure lactic acid is produces and bacteriocins (biologically active substances) are released. They have a beneficial effect on the human body. During reproduction Streptococcus thermophilus produces the enzyme alcohol dehydrogenase. That enzyme helps the faster breakdown of ethyl alcohol and recovery of the body after alcohol intake.

The products containing the probiotic microorganisms from the association – Lactobacillus bulgaricus, Lactobacillus helveticus, Lactobacillus lactis and Streptococcus thermophilus have a good antimicrobial activity against harmful (pathogenic) microorganisms. They have a moderate bactericidal effect – kill pathogenic strains of Staphylococcus aureus, which causes purulent inflammatory processes. Probiotic microorganisms exhibit a strong bacteriostatic effect – stop the growth of harmful strains of Escherichia coli, Salmonella, Shigella flexneri, Proteus mirabilis and Staphylococcus aureus, which cause severe disorders of the gastro-intestinal tract and other human organs – diarrhea, disbacteriosis and inflammations.

The probiotic bacteria from the association increase human body resistance to harmful microorganisms, which determines their health effects.

The probiotic products of Daflorn contain in 1 g over 1 x 108 live cells of the all natural strains, isolated from spring water – Lactobacillus bulgaricus, Lactobacillus helveticus, Lactobacillus Lactis and Streptococcus thermophilus. Their amount is enough and it determines their health benefits.

Main advantages of the probiotic association of Daflorn

  • Completely natural, isolated from spring water, unique probiotic strains
  • Maximal high survival and resistance during the production process
  • Maximal high survival and resistance during storage at a room temperature
  • Maximal high survival and resistance during passing through the gastrointestinal tract
  • Maximum bioavailability
  • Maximum beneficial effect against pathogens

Nutritional agents in the products

The products of Daflorn contain not only probiotic microorganisms but also nutrients. During the biotechnological process with the help of probiotic microorganisms from the association milk proteins and casein break down to all 21 essential and non-essential amino acids – Cystine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Tyrosine, Valine, Alanine, Arginine, Aspartic Acid, Glumatic Acid, Glicine, Astidine, Histidine, Hydr. Proline, Proline, Serine, Lisinoalanine. Milk fats break down to polyunsaturated milk acids. During that process probiotic microorganisms and in particular Lactobacillus bulgaricus breaks down lactose. Lactic acid bacteria from the association break down the long chains of nutrients, contained in milk during fermentation to nutritional components ready for absorption. By taking these nutrients the human system does not use up energy and thus spares the organs.

Amino acids

The products contain not only the non-essential but also all essential amino acids that the human body cannot produce as thus they should be imported by food ready to be absorbed. The proportions of the essential and non-essential amino acids is from 1:2,2 to 1:2,4. The probiotic product with these parameters meets the recommended international requirements for a standard protein food product. Amino acids in the product are ready for absorption by the organism as building units of the cells and thus people do not overload the liver and pancreas to break down the proteins.

Probiotic products contain the most important muscle building amino acids – Leucine and Arginine. In the products they are ready to be directly absorbed and to build muscle filaments. The products contain also Lysine, Methionine and Tryptophan in large amounts. These amino acids are essential and are of animal origin. They participate in the breakdown of the other proteins of plant and animal origin (phytoproteins, casein, whey protein). Without them the breakdown of the other types of proteins is incomplete, they cannot be absorbed by the system and cause putrefactive processes in the large intestine and intoxication of the body. The product also contains the so called „Cocktail of life“ – the amino acids Leucine, Isoleucine and Valine, which prolong life according to Italian scientific research from 2010.

Fatty acids

The probiotic products contain the main types saturated and unsaturated fatty acids. They contain an appropriate for the body amount of low molecular capric, caprylic, caprynic and lauric acids that have an expressed anti-atherosclerotic effect. They also contain the essential lipoic and linolenic acids which the body cannot produce alone and they must be imported from outside by food. The products contain the optimum and balanced amount of fatty acids with a carbon number from 6 to 12 and from them the human body produces steroids and sex hormones which are very important. The products of Daflorn do not contain cholesterol. The company also offers low fat and defatted products.

Carbohydrates

In the probiotic products of Daflorn carbohydrates are broken down biotechnologically to easy for absorption monosaccharides – glucose and galactose as during production some of them are partially caramelized and give a nice natural caramel taste to the product. They easily reach and are instantly absorbed by the brain and liver. During fermentation Lactobacillus bulgaricus breaks down lactose because it feeds on it. The products are low lactose to lactose-free and are suitable for people with lactose intolerance. The products do not contain gluten and are suitable for people with gluten intolerance.

Vitamins and minerals

The probiotic products contain also the basic minerals – calcium, potassium, phosphorus, iron, etc. They are components of milk in the form of soluble compounds as they are fully absorbed by the human body. Calcium has a structural role in the human body as it is an essential element in bones and teeth building. Phosphorus participates in calcium metabolism and plays a principal role in its absorption. Iron is an essential element necessary for the hemoglobin production. Lack of iron can lead to reduced hemoglobin in blood and hence anaemia and fatigue.

The products also contain a number of milk vitamins which are of a great importance for the organism – Vitamin A, Vitamin B1, B2, Carotene. Vitamin A (retinol) is necessary to the eye retina to improve vision in low-light and for colour vision. It contributes to formation of growth factor. Carotene is a precursor of Vitamin A, i.e. Vitamin A is generated from it. Vitamin B1 (Thiamine) stimulates production of energy from glucose. Lack of that vitamin leads to neurological dysfunctions. Vitamin B2 (Riboflavin) participates in oxidative reactions of the respiratory chain. The content of vitamin D3 is essential because it is very important for the full absorption of calcium by the human body. Vitamin D3 is essential for people who live in northern areas and regions with less sunshine.

The combination of micro elements, minerals and vitamins from group B and A, which are actively involved in many essential metabolic processes, leads to balancing the basic metabolic processes in the human body.

The probiotic products of Daflorn are completely natural as they do not contain preservatives, colouring agents, synthetic and harmful substances and genetically manipulated microorganisms.

  • they do not contain gluten
  • they do not contain cholesterol
  • they are lactose-free to low-lactose

We add coffee, herbal extracts, oils, fibres, enzymes, honey to some of our probiotic products. The amino acids of the probiotics in these new products serve as a fast transport carriers as they catch the molecules of the added extracts and carry them quickly to the cells. Thus they potentiate the faster and full effect of the added coffee, herbal extracts and honey. By the unique combination of wild all natural probiotic microorganisms, nutrients, coffee, herbal extracts and honey the products of Daflorn endow body and mind with greater welfare.


Food allergy

Food allergy

Epidemiological study of patients with food allergies

M. Peneva, MC „Evrozdrave-Bulgaria”, excerpt from Abstract of dissertation, Sofia 2016, p. 27-29

Food allergies have significant harmful effects on families, economics, social interactions, school, work and service, as well as on quality of life related to health.

According to the medical observations, people with higher living standard and more active immune prophylaxis are more often affected by allergies.

The incidence of allergic diseases is increasing among all age groups. One of the most common allergies is the food allergy. For example, allergy to peanuts has doubled over the last decade. Food allergy is defined as an immunologically mediated hypersensitivity reaction to food proteins that are harmless, but alien to the human immune system. Major risk factors for the emergence and development of food allergy are the family medical history and environmental factors, especially important of which is the intake of foreign proteins such as cow’s milk, eggs, fish, soy.

A clinical study of food allergies involving 58 patients aged between 3 and 81 years was conducted in MC Evrozdrave in the period 2009 – 2014 in cooperation with specialist physicians. 6 of the patients were children aged from 3 to 9 years. 29 patients were women aged from 22 to 81 years and 23 were men aged from 24 to 71 years. All patients had different manifestations of allergic reactions. In some of them we observed classic symptoms of allergy – lacrimation, rhinitis, various rashes, itchy skin, diarrhea. In some patients we observed newly found symptoms of food allergy – hair loss, dandruff, periodontal disease, elevated levels of prolactin in young women. All patients have undergone immunoassay tests for 19 groups of food allergens by the ELISA method – immunomodulation for determination of the number of the specific antibodies against certain food allergens in blood serum. The patients were submitted to allergy tests to 19 groups of food proteins. All patients were found to be hypersensitive towards more than one food allergen.

The high percentage of food allergy to peanuts, seafood, strawberry, egg whites, cocoa and cow’s milk should be noted. Only one patient was found to be allergic to goat’s milk. Most likely this is due to the fact that the composition and nutritional functions of goat’s milk are the closest to the breast milk. A difference should be made between allergy to milk proteins and insufficient production of the enzyme lactase in the body, which enzyme breaks down lactose (milk sugar). After establishing the type of food allergy, we advised all patients to stop the consumption of food containing the respective food allergens, we recommended antiallergenic treatment with claritine 1 to 2 tablets daily depending on the severity of the allergy and probiotic treatment with Laktera Nature 15 g daily dose in combination with Laktera Rose oil 2 capsules a day. The probiotic dietary therapy for the patients with an established allergy to cow’s milk protein was a probiotic with goat’s milk Laktera Allergy free 15 g daily dose in combination with Laktera Allergy Free Rose+ – 2 capsules a day. Probiotics containing Lactobacillus bulgaricus combined with Bulgarian rose oil significantly reduce allergy symptoms and the allergic predisposition of the body.

Additionally, but not related to the allergic process, Lactobacillus bulgaricus improves lactose digestion and it has an approved health claim pursuant to Regulation 432/2012 of the European Union. Clinical symptoms of food allergy have faded away for a period of 2 to 6 weeks depending on the severity of allergy. We explained to the patients that they have to select and purchase food products carefully by checking the information on the labels about the composition of the food and the allergens contained therein. We advised the patients to actively look to allergens in the menus of the public restaurants.

The results of the study show that allergic diseases have increased considerably over the last decade. Food allergy can now be referred to the socially significant diseases. Obviously, food allergy is widely spread among the working-age population and necessitates specialized medical care. It requires a complex therapy with medical specialists, health managers and experts on food safety. Food allergy causes great social, economic and psychological damages to the population. People suffering from food allergy should be concerned with their health keeping anti-risk behavior and healthy lifestyle by active and targeted search of allergens in products before consumption.

Anticancer activity of probiotics – experimental and clinical studies

Anticancer activity of probiotics – experimental and clinical studies

Georgi Alexandrov1, Kaloyan Georgiev2, Marieta Georgieva2, Ivan Iliev3, Maria Peneva4

Abstract

Introduction: Many scientists have been working on the anticancer effect of probiotics for the past decades. In the middle of the last century I. Bogdanov proved experimentally that Lactobacillus subsp. bulgaricus inhibits the growth and proliferation of tumor cells of Sarcoma 180, implanted in rats. Kitadzava (Japan) ascertained good anticancer effect of fermented milk on rats with implanted tumor cells. A. Hosono (Japan) found out that anticancer effect of fermented milk is due to the lactic acid bacteria and polysaccharides contained in it. Our preliminary studies showed that probiotic Laktera Nature® has an anti-proliferative effect against aggressive colon carcinoma cell line HT-29. The probiotic Laktera Nature® contains original strains of Lactobacillus bulgaricus DWT1 and Streptococcus thermophilus DWT4, isolated from spring water in Bulgaria and 21 natural essential and non-essential lactic amino acids. The aim of this study is to determine the anticancer activity of the different ingredients of probiotic Laktera Nature® and to study the effect of the probiotic formula as a nutritional therapy in patients with colorectal cancer.

Materials and Methods: Four types of cell lines have been used: 3T3, BJ, HT-29 & MDA-MB-231. Cytotoxicity was determined by MTT-dye reduction assay. The direct cytotoxicity of the tested cell lines, measured at the 24th hour and the antiproliferative activity, measured at the 72nd hour have been studied. Four different samples of Laktera Nature® were used: sample 1 (original probiotic formula containing live cells of Lactobacillus bulgaricus DWT1 and Streptococcus thermophilus DWT4 and 21 lactic amino acids), sample 2 (only the probiotic strains without the amino acids), sample 3 (only the 21 lactic amino acids without the probiotic strains) and sample 4 (the original probiotic formula that has passed γ-sterilization 10 Gy, whereby the probiotic strains are killed, leaving only the cell walls). The clinical study is carried out on 13 patients with surgery for colorectal cancer and undergoing chemo- and radiotherapy. Half of the patients take 15 g daily dose Laktera Nature® (sample 1) as a nutritional therapy.

Results and Discussion: The four samples show a negligible direct cytotoxicity of the tested cell lines measured at the 24th hour. Samples 3 and 4 show a slight concentration- and time-dependent cytotoxic effect. It was interesting to observe that sample 2 (only the probiotic strains) did not have the expected inhibitory effect on carcinoma growth (in that case MDA-MB-231), it even increased its growth. Sample 1 (the original probiotic formula Laktera Nature®, containing live probiotic strains and 21 amino acids) demonstrated a significant growth inhibition of cancerous HT-29 and MDA-MB-231 cell lines with IC50 values – 711,69 ± 82,1 and 934,21 ± 43,5 mcg/ml respectively, measured at the 72nd hour. The parallel conducted clinical trial shows that the nutritional therapy with the original probiotic formula Laktera Nature® allows the full courses of treatment with chemo- and radiotherapy to be carried out and reduces the side effects of the chemo- and radiotherapy.

Conclusion: The original probiotic formula Laktera Nature® inhibits growth of cancerous HT-29 and MDA-MB-231 cell lines. The nutritional therapy with Laktera Nature® improves quality of life and increases the survival rate of patients with colorectal cancer.

Effect of probiotic product Laktera Vision+ with Lactobacillus bulgaricus and extract from bilberry on dry eye syndrome and tired eye syndrome

Effect of probiotic product Laktera Vision+ with Lactobacillus bulgaricus and extract from bilberry on dry eye syndrome and tired eye syndrome

Technology development and penetration of computers in life lead to refractive anomalies of the eyes in more young people and they start to wear glasses or lenses for vision correction at a young age, before the occurrence of age-related changes (presbyopia). Excessive congestion of eyes at a young age led to the occurrence of new syndromes in ophthalmology – dry eye syndrome and tired eye syndrome.

There are lots of myths as well as lots of studies for the positive effect of bilberry on the eye health.

Bilberry (Vaccinum myrthilus) is a perennial shrub with a height up to 35 cm, which grows in forests and mountain regions of Northern Europe, West Asia and North America. Its fruits are small with a black-violet colour and a pleasant sweet sour taste. (1)

The ancient Roman army physician Pedanius Dioscorides (40 AD), who is considered to be the founder of botany, in his book „De materia medica“ recommends bilberry in treatment of diarrhea and scurvy. (2)

100 g bilberry fruit contain 86,5 g water, 1,1 g proteins, 8,6 g carbohydrates, 2,2 g fibres, 1,2 g free organic acids, 51 mg potassium, 6 mg sodium, 16 mg calcium, 6 mg magnesium, 13 mg phosphorus, 7 mg iron, 0,9 mg copper, 0,01 mg Vit. B1, 0,02 mg Vit. B6, 0,3 mg Vit. PP, 10 mg Vit. C. They are very rich in anthocyanides from the group of flavonoids. (1) Anthocyanides are very important for the eye health. Eye lens and retina are exposed to prolonged intense light radiation and singlet oxygen more than any other tissue in the human body. Thus free radicals are formed and they combine with the lipids in the photoreceptor cell membrane (rods and cones), responsible for vision. To keep the eye tissue healthy it must have an effective antioxidant protection. Anthocyanides in the bilberry are powerful antioxidants and help in the fight against cellular degeneration of the retinal cells caused by free radicals. Anthocyanides help to maintain the normal blood flow in the fine blood vessels (capillaries) that feed the eye tissues. (3)

Bilberry is often associated with the improvement of vision at night. The story that during the World War II pilots have taken bilberry jam to sharpen their vision in night missions is very popular. An American clinical study in 2000 on pilots from the U.S. Navy did’t find such effect. (4)

Experimental research of rats show that the use of bilberry extract can inhibit the development of macular degeneration and senile cataracts.(5)

Object of observation were 41 people aged between 21 and 44 years. 24 of them were men and 21 – women. All of them wear glasses for vision correction, as 17 (41.46%) are shortsighted with dioptre from -0.5 to -3d, and 24 (58,54%) are far-sighted with dioptre + 0.5 to + 2d. 28 (68,29%) of them are with astigmatism. 24 (58,13%) of them wear glasses and lenses for vision correction. All of them work in offices (government officials, IT specialists, accountants, etc.) from 4 to 9 hours a day in front of computers an average 5 hours a day. All wear anti-reflecting glasses while working on a computer.

Most frequent syndromes that occur in these people are the dry eye syndrome and the tired eye syndrome. The dry eye syndrome manifests with reduced production of tears, irritation and itching of eyes. The syndrome of tired eye which is a kind of dryness of eyes occurs after continuous work on a computer with red eyes, marking and expansion of capillaries, blurred vision.

The study was carried out within 8 weeks (56 days). 35 of people have taken 2 capsules Laktera Vision + every day before meal. 6 of the observed people have taken Laktera Vision + irregularly – on average 2.5 times a week. Each capsule (320 mg) contains over 20 billion live cells of Lactobacillus delbrueckii spp. bulgaricus, Streptococcus thermophilus, Lactobacillus helveticus, Lactobacillus lactis (isolated from spring water in Bulgaria), 21 amino acids, milk vitamins, minerals and 10 mg dry extract of bilberry (Vaccinium myrtillus), standardized to 25% anthocyanides.

The results from the study are presented in Table 1.

Days % patients with dry eye syndrome % patients with tired eye syndrome
0 70,73 85,36
7 17,07 21,95
14 14,63 19,51
28 12,20 17,07
42 14,63 17,07
56 12,20 14,63

The table shows that the syndromes of dry and tired eye can be put under control very quickly, in the first week after administration of Laktera Vision +. During the eighth week of the study the dry eye syndrome was observed in 12.2 % (5) of the cases and the tired eye syndrome – in 14.63% (6) of the cases. The medical history for those who have not taken the probiotic product with bilberry extract regularly shows that when they have not taken the product for 3-4 days the syndromes occur again. After administration of the product manifestations of the syndromes are put under control for a period of 12 – 24 hours.

Usually the free market offers products which contain in 1 capsule from 5 to 150 mg bilberry extract. In our observation the effect is achieved with 20 mg bilberry extract daily. The smaller necessary daily dose of dry bilberry extract is probably due to a specific amino acid or group of amino acids in the probiotic product, that acts as a transport carrier of the molecules of the extract and potentiate the effect of the anthocyanides in bilberry. Identification of the amino acid or the group of amino acids, responsible for that process, is a subject of further study.

The probiotic product with bilberry extract controls successfully the syndromes of dry and tired eye, occurring in young people wearing glasses for vision correction, who work on a computer more than 4 hours a day.

Nutritional therapy for oncological diseases

Effect of a probiotic product containing a strain of Lactobacillus bulgaricus DWT1 on preventing adverse effects during adjuvant therapy for patients with tumours of the stomach, colon and rectum

Summary

Previous experience in oncology. The studies of some strains of Lactobacillus bulgaricus have shown that they have antimutagenic effect. Some experiments on animals show a certain beneficial effect in cases of colorectal cancer in rodents. A population study noted lower levels of occurrence of colorectal cancer among a considerable group of fermented dairy products consumers.

Tumours in the digestive system are of exclusive importance because of their high frequency rate and because of the great importance of the digestive system for the whole body. Nutritional therapy that improves digestion is very important for the treatment of the underlying disease as well as for the symptomatic treatment. On the other hand, adjuvant therapy, i.e. the specific oncological treatment /chemo- or radiotherapy/ often leads to a number of healthy tissue damages and to serious complications and side effects. These complications inhibit the beneficial effects of treatment and even make it impossible. Cytostatics cause nausea and vomiting during and after application of chemotherapy and overtaking vomiting due to inadequate antiemetic prevention in previous chemotherapy. Mucositis is an extremely serious side effect after both chemotherapy and irradiation in the area of head and neck. It concerns inflammatory changes of the mucous membrane of the digestive system. It often occurs in parallel with myelosuppression and leukopenia. The most dangerous consequence of leukopenia /decrease in the number of leukocytes/ is febrile neutropenia that requires hospitalization, blood transfusion and often leads to discontinuation of cytostatics and the quality of life is getting worse. Anorexia and cachexia /weight loss/ are frequent in patients with tumors of the digestive system and adversely affect the successful treatment, tolerance of treatment and indirectly affect survival. Radiotherapy causes adverse effects depending on the total dose, fraction size, field of irradiation, interval between fractions, type of radiotherapy and specificity of the irradiated tissues. The toxic effects of radiotherapy are dyspepsia, gastritis, ulceration /ulcers/ and radiation enteritis.

Results. The study included 80 patients with tumours of the stomach, colon and rectum. All of them have undergone a patho-histological examination and the disease stage was precisely defined. In this randomized study patients were divided into two groups of 40 patients. The first group of 40 patients was undergoing chemotherapy or chemoradiotherapy. The other group of 40 patients was taking probiotic food, containing strain of Lactobacillus bulgaricus DWT1 – 15 mg once a day before breakfast for three months, in addition to the chemotherapy or chemoradiotherapy.

The obtained results show that probiotics, containing a strain of Lactobacillus bulgaricus DWT1, have a potential beneficial effect as taken in addition to the treatment of cancer patients with adjuvant chemotherapy or chemoradiotherapy. Administration of that probiotic product influences on the reduction of nausea and vomiting and maintains appetite of patients during the adjuvant therapy. There is a clear bond between reduction of the frequency and severity of disorders and the intake of Lactobacillus bulgaricus DWT1.

Nutritional therapy with probiotic product, containing a strain of Lactobacillus bulgaricus DWT1, helps the prevention of the adverse effects during adjuvant therapy.

Cytotoxicity of Bulgarian spring water probiotics (probiotic Laktera Nature®) on colon carcinoma cell line

Cytotoxicity of Bulgarian spring water probiotics (probiotic Laktera Nature®) on colon carcinoma cell line

Abstract

Colorectal carcinoma is a malignant disease, from which more than 1 million people worldwide suffer. Over the past two decades, its social significance attracts more attention. Colorectal cancer is the second leading cause of death from malignancy and the third most frequently diagnosed malignancy. It has been estimated that nutrition is the main reason for the high incidence of cancer. Probiotics are live microorganismswith proven health benefits in a variety of gastrointestinal diseases, and disorders outside the gastrointestinal tract. In this study, we wanted to explore cytotoxicity and anti-proliferative activity of the new probiotic Laktera Nature® on non-cancerous cell lines – 3T3 and BJ and colon adenocarcinoma cell line – HT-29. Probiotic Laktera Nature® has weak direct cytotoxicity against 3T3 and BJ cells, but inhibits their proliferation in a dose-dependent manner. On carcinoma cell line – HT-29, in low concentration range (2-125 µg/ml) probiotic Laktera Nature® stimulates proliferation; at high concentrations (250-1000 µg/ml) we detected concentration-dependent inhibition of proliferation. Probiotic Laktera Nature® has shown promising primary screening results, which should be clarified as mechanisms in further works.
