Morphobiochemical indices of blood of brown bears

Argued for unified blood sampling in brown bears, an internal vein is proposed. Sex differences in most of the studied parameters were absent. The exceptions were total protein (higher in females) and glucose ((higher in males). Seasonal dependence of the values of indicators occurred in relation to urea (higher in winter) and total bilirubin (higher in summer). The level of alkaline phosphatase was slightly lower in males, as noted in the literature in relation to man. The influence of the season of the year did not affect the level of alanineaminotransferase, whereas the amount of alkaline phosphatase was higher in winter, and aspartateaminotransferase, on the contrary, in summer.
