Abstract

The aim of the work was to determine some biochemical parameters, taking into account the sex of the outbred (conventional) rats in the norm, used at the experiment to determine the reference values. The experiments were carried out on 41 rats of 5-6 months age old., weighing 200-250 g, divided into two groups - males (n = 16) and females (n=25). Blood serum was obtained according to the generally accepted method. Blood serum was obtained according to standard methods. Biochemical parameters were analyzed on an IDEXX CatalystOne automated analyzer. Protein and carbohydrate metabolism were analyzed by the serum levels of total protein (TP), albumin (Alb), urea (Urea), creatinine (Creat), glucose (Glu), the enzyme spectrum - by alkaline phosphatase (ALP), alanine and aspartate aminotransferase (ALT and AST), mineral metabolism - by calcium (Ca), phosphorus (P), sodium (Na), potassium (K), chlorine (Cl), as well as bile pigment - by total bilirubin (T.bil). De Ritis coefficient (AST / ALT), globulin (Glob), albumin/globulin ratio (A / G) was revealed by the calculation method. The results were taken into account in two versions: 1 - according to all animals (16 males and 25 females); 2 - according to samples from the general population in three replicates. It was found that out of 17 biochemical parameters -15 are constant, due to the sex of the experimental animals. So, females showed higher indicators of protein and mineral metabolism, glucose, ALT, alkaline phosphatase, while in males this was recorded only in four cases - in the content of urea and aSt and in the ratios A / G, AST / ALT. Data on the content of creatinine and total bilirubin in the blood serum of rats were variable in nature and were close in value. Thus, the results of the studies carried out can be used in the future, for biochemical diagnostics of systematic metabolic changes during various manipulations.
