[Possibility of using tumor markers, pituitary gonadotropic hormones and prolactin in the diagnosis of breast cancer].

The levels of gonadotropic hormones, prolactin, carcinoembryonic antigen (CEA) and ferritin were measured in 111 females (52--cancer, 32--benign tumors and 27--healthy controls in menopause). Radioimmunologic study showed a significant increase in prolactin, CEA and ferritin levels in patients with T1-2N0M0 breast tumors.

[Enzymatic hydrolysis of fat in the presence of Lamblia duodenalis (in vitro)].

The influence of Lamblia on the hydrolysis of fat by lipase was studied in vitro. The hydrolysis rate of fat in the presence of live Lamblia and without them was determined colorimetrically by the quantity of the formed glycerine. In addition, the kinetics of this reaction was studied by the method of compensating potentiometry by neutralization of fat acids with alkali.
