[Changes in alkaline phosphatase activity and blood phosphorus levels in healthy persons and patients with peptic ulcer].

Venous blood total phosphatase activity, its thermostable fraction, and inorganic phosphorus levels were measured thrice within 20-64 min in the course of registration of regular motor activity of the gastrointestinal tract in 38 men aged 18 to 57 (9 healthy and 29 with peptic ulcer). These parameters changed within a wide range over the mentioned period; besides, they depended on the individual features of the organism. Using the chi 2 test at the 5% significance level the authors have demonstrated that total blood alkaline phosphatase activity is increased by the end of a regular cycle in the gastroduodenal system.

[Morphohistochemical study of the rat placenta administered a hepatotropic poison at different periods of pregnancy].

Intragastric administration of CCl4 (0.3 ml per 100 g of body weight) to female rats caused a marked injury of the placental tissue and particularly of the chorionic epithelium of the labyrinthine portion with the maximal development of dystrophic necrobiotic processes on the 14th-16th day of pregnancy (when the poison was administered 48 hours before the animal was sacrificed). There was noted an increase in the number of mitoses in the epithelial cells at all the periods, and a statistically significant enlargement of the nuclei and the nucleoli of the cytotrophoblastic cells on the 17th--18th day of the intrauterine fetal development.
