Increasing the efficiency of the herd reproduction system by introducing innovative technologies into dairy farming in Northern Kazakhstan.

Background And Aim: In recent years, Kazakhstan has increasingly imported breeding cows for dairy and beef production. To maintain and improve their breeding qualities of reproductive function, it is necessary to constantly monitor the herd reproduction system. The aim of this study was to increase the level of herd reproduction by introducing innovative technologies into dairy farms in Northern Kazakhstan.

[Effect of Mycobacterium tuberculosis on activity of lysosomal enzymes in mouse peritoneal macrophages].

The studies of the effects produced by M. tuberculosis various strains on the activity of lysosomal enzymes in peritoneal mouse macrophages demonstrated multidirectional influence of the bacilli. Non-sedimentary activity rose in matrical enzymes indicating lysosomal membranes instability due to M.

[Preclinical ECG changes and their evaluation based on the criterion of symmetrical approach].

To reveal preclinical cardiac performance changes, conventional and unique ECG processing procedures were used in 101 individuals. A classification of heart function was developed, which was based on a comprehensive assessment of ECG. The results of the clinicofunctional classification were well comparable with those of a quantitative ECG analysis made with heuristical methods.

[Biotransformation of the 14C-hydrogenated analog of phenazepam in inbred mice].

The elimination of 14C-hydrogenated analogue of phenazepam and its metabolites was studied in inbred C57B1/6 (B/6), BALB-c (C) and CBA mice. The kinetics of two-phase elimination of 14C-compounds with urine and feces was similar in all the above mouse strains. The excretion was realized mainly with feces, exceeding elimination with urine 5-6-fold in B6 mice and 10-11-fold in C and CBA mice.

[Distribution of the 14C-hydrated analog of phenazepam in the organs and tissues of mice].

The absorption kinetics of hydrated phenazepam analog into the liver, spleen, brain, kidney, blood, lungs, heart, skeletal and fat tissues is studied at 0.25-24 hour intervals after its intraperitoneal (i/p) administration to mice. Drug concentration in the above mentioned organs was maximal 0.
