Pertaining to the scenario at hand milk samples from Holstein x Hariana crossbred cows were investigated for alternation in enzyme activity as influenced by sub clinical mastitis (SCM) and their percent sensitivity,specificity,accuracy,positive and negative predictive values, positive and negative likelihood ratios and correlation with (somatic cell count) SCC were calculated. It was found that SCM influence significantly the activity of ALP at pO.OIand LDH at pO.O5in milk. Aspartate amino transferase activity was not influenced by SCM in milk. Moreover, both were found to be correlated with somaticcellcount, significantly.Fromthe likelihoodratios itwas clearthat both alkalinephosphatase (ALP) and LDH can be used for diagnosis of SCM, but, ALP is the safe indicator of SCM in the present study.

There was studied the feature of hematological and biochemical blood indicators of rats at action of acute ionising radiation against acute stress influences. Results of research of hematological and biochemical blood indicators of rats developing under influence of stress and radiating factors are presented. It is established, that on 4 days twenty-four-hour period after the influence of pointed ionizing radiation against a background of pointed stress impact some changes become evident. They appear in reducing of total number of leucocytes, haemoglobin, hematocrit and general albumen, and also in increase of such ferment activity as lactate dehydrogenase, creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase. | Целью исследования является изучение особенности гематологических и биохимических показателей крови крыс при действии острого ионизирующего излучения на фоне острого стрессорного воздействия. Представлены результаты исследования гематологических и биохимических показателей крови крыс, развивающихся под влиянием стрессорного и радиационного факторов. Установлено, что на 4 сутки после действия острого ионизирующего излучения на фоне острого стрессорного воздействия отмечаются изменения, выражающиеся в снижении общего количества лейкоцитов, гемоглобина, гематокрита и общего белка, а также увеличении активности ферментов лактатдегидрогеназы, креатинфосфокиназы, аспартатаминотрансферазы и аланинаминотрансферазы.
