The effects of nonstarch polysaccharides with different molecular weights on the development of Lewis’ lung carcinoma and efficiency of cyclophosphamide therapy in mice were studied. Treatment with these substances with low molecular weights (<30 kDa) caused no changes in the primary tumor growth, but inhibited its metastasizing, while nonstarch(More)
Standard models of experimental ulceration (of neurogenic origin, H. Shay ulcer, indomethacine-, ethanol-, prednisolone-, histamine- and acetate-induced ulcers) were used to demonstrate protective effect of non-starch polysaccharides (potassium alginate, potassium pectate, low-esterified pectin). Potassium pectate proved to be the most efficacious(More)
Both chronic (prophylactic) and single administration of standardized calcium pectate considerably increased the resistance of rat stomach mucous membrane with respect to ulcerogenic factors of various etiology, including immobilized stress, indomethacin, ethanol, prednizolone, and histamine, according to H. Shay's model. The gastroprotective effect of this(More)
Anti-inflammatory and analgesic activities of the complex of flavonoids from Lychnis chalcedonica L. were studied in the models of acute aseptic inflammation induced by carrageenan, histamine, and serotonin and acetic acid-induced painful chemical stimulation. It is demonstrated that course treatment with flavonoids derived from Lychnis chalcedonica L.(More)
Experiments on C57LB/6 mice with transplanted Luis lung carcinoma showed that the officinal Echinacea purpurea preparation did not influence the efficacy of cytostatic therapy. This echinacea preparation did not change the development of metastases and even stimulated the tumor growth. In contrast, a hydrophilic polysaccharide complex isolated from(More)
The effects of various alginate forms on the development of transplanted tumors in mice and efficiency of cytostatic therapy were studied. High-molecular-weight Ca and Na alginates, acid-soluble hydrolysate, and sodium alginate fraction inhibited the growth of Ehrlich adenocarcinoma. The use of acid-insoluble sodium alginate in chemotherapy protocol(More)
Calcium pectate has been found to exhibit an antiulcer activity in rats with model of chronic ulcers. Course treatment of the experimental animals with calcium pectate (i) accelerated the repair of experimental damage due to better integrity and higher secretory activity of epithelium and (ii) decreased hemodynamic disorders in surrounding mucous and(More)
Polysaccharides from Tussilago farfara L., Acorus calamus L., and Echinacea purpurea (L.) Moench attenuated the toxic effect of fl uorouracil on the small intestinal epithelium of mice with Lewis lung carcinoma. Addition of polysaccharides to chemotherapy protocols stimulated reparative regeneration processes in the small intestine damaged by the cytostatic(More)
Experiments on C57B1/6 mice showed that ginsenoside Rh2 inhibited the growth and metastasis process of Lewis lung tumor and increased the antitumor and antimetastatic effects of cyclophosphamide. On the model of transferred melanoma B-16, ginsenoside Rh2 showed a tendency to increase the antiblastome effect of the cytostatic drug.
