[Receptive status of the endometrium in patients with benign ovarian tumors before and after organ-preserving operations].

Unlabelled: Background. Benign ovarian tumors (BOT) occupy the 2 place in the structure of diseases of the female genital organs. In 20% of women of reproductive age, BOT are associated with infertility.

[Changes in lipid metabolism and renewal of sialic acids in the composition of glycoproteins of adipose tissue during carbohydrate loading].

With an increase in content of sugar in a diet from 10% to 50% of the caloric value the rate of synthesis and accumulation of lipids were increased in perinephric adipose tissue of rats exhibiting the maximal values at 30% content of sugar in rations. Under these conditions content of insulin was decreased in blood and half-life of sialic acids was decreased in glycoproteins of adipose tissue. Interrelationship between sensitivity of the adipose tissue receptors to insulin and the half-life of sialic acids was considered.

[Effect of fructose on the hexosamine turnover in the rat crystalline lens].

Rats were given isocaloric rations containing starch (control) and varying amounts of fructose as carbohydrates. Hexosamines were isolated from the lens, glycoproteins--from the blood serum, and their turnover was studied. A drastic deceleration of hexosamine turnover in the lens was observed at high-fructose diets (20 and 40% of fuel value), while glycoprotein turnover in the blood plasma was not changed as compared to the control, glucose-6-phosphate dehydrogenase in red blood cells was decreased, insulin level was lowered, and glucose level in the blood serum rose insignificantly.

[Turnover of hexosamines in the lens and glycoproteins in the blood of rats given a xylose-containing diet].

To elucidate the action of xylose admixtures during the biotechnological production of monosaccharides, rats were given rations containing xylose that comprised 2.10 and 20% of the total amount of carbohydrates. Hexosamines of the lens and general blood globulin fraction were isolated and their turnover was investigated.
