[The preclinical diagnosis of threatened abortion and late gestosis in pregnant women with normal body weight and obesity].

Measurements of blood serum phosphatidyl inosites in pregnant women with normal body mass and with obesity in whom pregnancy ran normal or pathological course showed that phosphatidyl inositol levels increased 2-3-fold in case of threatened miscarriage and decreased 2-3-fold if symptoms of late gestosis appeared (an abnormal gain in body mass) as compared to their levels in women with an uneventful course of pregnancy. Phosphatidyl inositol levels were higher in obese women that in those with normal body mass, no matter what the pregnancy course was.

[Thrombogenicity of the arterioles and venules in experimental tumor growth].

The authors studied laser radiation induced thrombogenesis in microvessels--arterioles and venules--of the mesentery of tumor-carrier rats. Statistically significant increase of thrombogenic potential was revealed in the venules on the 7th day after reinoculation of Pliss' lymphosarcoma, and only a tendency to its increase in the arteries. At the same time an increase was noted of the aggregation activity of blood platelets and inhibition of their deaggregation.
