Seasonal Variability of Biochemical Parameters in Female Cynomolgus Macaques (Macaca fascicularis).

ABSTRACT

We study of seasonal variability of biochemical parameters of blood serum in female cynomolgus macaques (Macaca fascicularis) in the Adler nursery of the Research Institute of Medical Primatology kept under conditions of free access to the open enclosure. It was found that in the most favorable season for monkeys (from June to September) the serum levels of sodium, phosphorus, creatinine were significantly increased and cholesterol and calcium concentrations and lactate dehydrogenase activity were significantly reduced. There was no seasonal variability in the content of triglycerides, urea, potassium, activity of γ-glutamyltransferase, ALT, and AST.
