[The division of the territory of Azerbaijan into districts by hydatid echinococcosis].

The epizootiological and epidemiological stratification of the territory of Azerbaijan on hydatid disease was made. Four zones were identified as low, moderately, highly and extremely endemic. These zones are differentiated from their climatic and social conditions for echinococcosis distribution, human incidence and prevalence, canine and ovine number and prevalence, and the time of survival of echinococcus eggs in the soil.

[Immunologic reactivity of patients with obstructive jaundice of non-neoplastic etiology].

Immunity values were studied in patients with obstructive jaundice of cholelithic etiology. The number of immune cells was reduced and the formation of antibodies was deficient in these patients in the preoperative period. The degree of immunodeficiency correlated with the duration of jaundice and the degree of bilirubinemia.
