(-)-Epigallocatechin gallate (EGCG), the most abundant component in green tea, has a potent anti-apoptotic activity. The purpose of this study was to investigate the protective effects of EGCG and their molecular mechanisms on high glucose-induced apoptosis of human lens epithelial cells (HLEB-3). HLEB-3 cells were exposed to various concentrations of glucose and EGCG. Cell death was assessed by MTT assay and flow cytometry using annexin V and propidium iodide. The expression of the Bcl-2 family, c-fos, c-myc and p53 was measured by real-time PCR. EGCG decreased the Bcl-2/Bax expression stimulated by a high glucose. Moreover, EGCG suppressed the high glucose-induced expression of c-fos, c-myc and p53. These findings suggest that EGCG protects HLEB-3 cells from high glucose-induced apoptosis by regulating the gene expression of the Bcl-2 family, c-fos, c-myc and p53. Thus, EGCG may have a potential protective effect against diabetic cataract formation.

The article presents a method of conservative treatment of men with I-II stage prostatic adenoma using a combination of doxazosin and indigal, which has antioxidant, antiproliferative and anti-inflammatory properties, that allowed improving urodynamic parameters and reducing the progression prostate adenoma, minimizing the adverse effects of treatment.

The magnitude of apoptosis of hepatocytes of rats that were within 2 weeks on a balanced complete semi-synthetic diet supplemented with extract of green tea, epigallocatechin gallate (EGCG), quercetin, coffein (1-4th experimental groups accordingly) is studied. The contents EGCG, quercetin and coffein in rats of 2-4th experimental groups correspond to their content in diet of rats 1 experimental group, and equally contents in tonic beverage. It is determined that application in diets extract of green tea and its compounds does not damage effect on hepatocytes of rats. The use of diets with the inclusion of extract of green tea, quercetin and coffein provides the clear tendency to stabilize the plasma membrane of hepatocytes comparison with rats of control group (rats fed the same diet but without the inclusion of the above-mentioned biologically active substances).

The efficacy of indigal plus containing indol-3-carbinol, epigallocatexin-3-gallat and Serenoa repens extract in combination with sparfloxacin was studied in a trial with participation of 30 patients with chronic infectious prostatitis associated with intracellular agents. Group 1 (n=15) received indigal plus (2 capsules twice a day for 3 months) and sparfloxacin (200 mg twice a day for 1 month). Group 2 including 15 matched controls received sparfloxacin alone according to the same schedule. The examination included questionnaire survey (IPSS, QoL, NIH-CPSI), blood count, urinalysis, PSA test, microscopy, bacteriological study of prostatic secretion, uroflowmetry, transrectal ultrasound investigation of the prostate with residual urine assay, laser doppleroflowmetry. The examinations were performed on the treatment day 30, 60 and 90. After the antibacterial treatment chlamidia, ureaplasma and E.coli were detected in 13.3, 6.7 and 26.7% patients of the control group, in 6.7, 6.7 and 6.7% patients of the study group, respectively. Thus, the addition of a pathogenetic drug indigal plus to sparfloxacin treatment promoted normalization of apoptosis of the infected cells, led to more effective bacterial eradication, enhanced regression of the symptoms. It is recommended to include indigal plus in a basic scheme of treatment of patients with chronic infectious prostatitis.

The effects of indol-3-carbinol and epigallocatexin-3-gallate on alteration and reparation in the urethra were studied in 30 male Shinshilla rabbits. From the observation day 2 the rabbits were fed with indol-3-carbinol and epigallocatexin-3-gallate in addition to standard diet. Microcirculation was assessed with a laser analyzer of capillary circulation LAKK-01 which detected earlier recovery of microcirculation in the group of the animals fed with indol-3-carbinol and epigallocatexin-3-gallate. Thus, antioxidant and antiproliferative properties of indol-3-carbinol and epigallocatexin-3-gallate improve alteration and reparation in affected urethra due to development of soft elastic connective tissue with better capillary circulation.

There was created new medical form of antiviral reparation Rodopes that surpassed previous forms - Rodopes adhesive ointment and Rodopes ointment - and also traditional preparations Zovirax and Interferon with its increased therapeutic effectiveness. Rodopes polymer films are much more comfortable way of clinical usage and can be successfully and widely used in stomatological practice.

One of the methods of increasing the quality of fatty products is including in their composition antioxidants, which provide the time of their conservation and improvement of their biological value. From this point of view calls concern a new drug epigallocatechina gallate. On the basis of these studies the prospects of usage were shown epigallocatechina gallate in fatty products and the paths of further applying in creation of food products.

Catechins and proanthocyanidins have been studied for their effect on initial stage of the protein biosynthesis. It has been found that (+)-catechin in all concentrations studied does not influence the intensity of t-RNA aminoacylation by 14C-glycine and 14C-arginine. Proanthocyanidins, namely, dimers B-3, B-6 and trimer C2 in the concentration of 10(-3) M completely inhibit the initial stage of the protein biosynthesis.
