Effects of nonstarch polysaccharides with different molecular weights on the development of Lewis lung carcinoma in mice and efficiency of cytostatic therapy

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 polysaccharides with high molecular weights (>400 kDa) inhibited the growth of Lewis' lung carcinoma node. Antimetastatic effects of cyclophosphamide were stimulated by low and high molecular weight polysaccharides.

Gastroprotective effect of natural non-starch polysaccharides

Experiments on mice and rats with modeled neurogenic and indomethacin-induced injuries to the gastric mucosa showed that preventive courses of calcium alginate, calcium pectate, and low-esterified pectin improved the resistance of the gastroduodenal mucosa to the destructive effect of the above factors.

Non-starch polysaccharides as correctors in cytostatic therapy of experimental tumors

We studied the effects of low-esterified pectin, calcium pectate, and alginate on the development of transplanted Ehrlich adenocarcinoma and Lewis pulmonary carcinoma and on the efficiency of cyclophosphamide treatment in mice.

Comparative Efficiency of Low-Esterified Pectin and Antistrumin during Experimental Hypofunction of the Thyroid Gland

We studied the effects of low-esterified pectin and antistrumin in rats with hypofunction of the thyroid gland modeled by enteral administration of lead acetate. Pectin more rapidly recovered thyroid function than iodine.

Effect of ionic carbohydrate-containing biopolymers on complement activation

We studied in vitro effects of charged polysaccharides on the classic and alternative pathways of complement activation. The complement system was affected by substances having different charges. Our findings suggest that the conformation of polysaccharide molecules, but not their charge, plays a primary role in the interaction with C1 and C3 complement components followed by initiation of cascade enzymatic reactions.

Effect of knotweed extract on alkeran-induced changes in rat ejaculate

We studied the effects of aqueous knotweed extracts in alkeran-induced experimental pathozoospermia. Therapeutic effect of knotweed extract in experimental cytostatic hypogonadism was demonstrated (the preparation improved spermatozoon motility).
