Cytochemical research the peripheral blood lymphocytes population structure of bottle-nosed dolphins

Results of cytochemical research of lymphocytes in healthy and sick bottle-nosed dolphins, maintained in captivity for various time are presented. Essential differences on parameters of nonspecific esterase and succinic dehydrogenase activity, glycogen content and correlations between them depending on animals state are revealed. Obtained data can be used at evaluation and correction of a course of dolphins adapta-tion to captivity.
