[B-lymphocytes in the peripheral blood of healthy cattle and in various gynecological and obstetrical cases].

The influence of mouse and horse complement on the detectability of EAC rosettes was compared. A slightly higher detectability of the rosettes was obtained by using horse serum as source of the complement. The percentage of lymphocytes B was determined in 26 head of cattle of ncb breed at the age of 2 to 14 years. In this group 11 animals were with gynecological and obstetric diseases, including 2 physiological deliveries and 1 case of catarrhal inflammation of the uterus, 4 complicated deliveries with Cesarean section and 4 Cesarean sections made prematurely in the 9th month of pregnancy. It was shown that inflammatory conditions within the reproduction organ as well as complications in healing of postoperative wounds result in a double increase of lymphocytes B in the peripheral blood, as compared to healthy animals.
