ABSTRACT
This work presents the results of the semi-quantitative evaluation of histochemical phosphatase activity in the sebaceous glands of the Kopetdag pine vole (Microtus socialis paradoxus Ognev et Heptner, 1928). The studies included the conversion of standard histochemical designations of enzymatic activity into digital analogues, allowing to evaluate the level of enzymatic activity and sexual dimorphism. In male voles, the index of the acid phosphatase enzymatic activity was 16% higher in summer than in winter. This index in female voles was less in winter than in summer by 28%. The index of the alkaline phosphatase enzymatic activity in male voles in summer higher than in winter by 4%. Female voles had the same seasonal differences. Male voles had higher July adenosine triphosphatase activity indexes in comparison with December indexes, but in females this situation was the opposite--summer values of activity were 16% less than winter values. Sexual dimorphism of acid phosphatase activity was greater in summer than in winter. Index of sexual dimorphism of alkaline phosphatase activity was twice less in summer than in winter, but their actual values were small. Maximum sexual dimorphism was observed in adenosine triphosphatase activity of during summer period, and it was greatly reduced in winter (from 27.0 to 4.0%).
