This study aimed to measure the biochemical markers including alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transferase (GGT), alkaline phosphatase (ALP), creatine kinase (CK), total proteins, albumin, globulin, albumin / globulin (A/G) ratio, glucose, blood urea nitrogen (BUN), and total bilirubin in sera of dairy cows from the period of February-2016 to March-2018. For this purpose, 78 dairy cows of >3 years old reared at some areas of Baghdad province were subjected to blood sampling from the jugular vein. Study values (mean ± standard error) of ALT, AST, GGT, A/G ratio and total bilirubin markers were found outside the normal ranges of international reference values. Conversely, ALP, CK, total protein, albumin, globulin, glucose and BUN were found within the normal ranges of international reference values. To investigate changes that occur during late stage of pregnancy, study animals were dividedinto two groups (non-pregnant lactating and pregnant dairy cows). Statistically, significant decrease (P<0.05) was encountered in values (M ± SE) of ALT, AST, and GGT enzymes; and significant increase (P<0.05) in ALP and CK values of pregnant compared to non-pregnant dairy cows. Data concerning the serum proteins, results also indicated a significant increase (P<0.05) in values of total protein, whereas there no significant differences (P>0.05) were showed in values of albumin, globulin and A/G ratio. Pregnant dairy cows were showed a significant increase (P<0.05) in values of BUN and total bilirubin; however, glucose appeared without significant differences (P>0.05). It has been concluded that the lactation and gestation periods have a great impact on activity of biochemical indices in blood of dairy cows; therefore, there is a need for constant periodic monitoring for the described indices in this study to maintenance on animal’s health status.

This study was conducted to determine the capability 0.5% H2O2 on drinking water, for the induction of oxidative stress status in female pregnant rats. Moreover, this study deal with role of this stress in initiation and development of atheromatous lesions via estimation the level of malondialdehyde (MDA) as lipid peroxidation index and Glutathione (GSH) as antioxidant index in aorta, heart and liver tissues as well as the histological examination of the that tissues.
The result elucidate study the levels of lipid profile parameters in all studied animal. In addition, the results showed histologizal lesions, represented by localization of fatty vacuoles foam calls in intimal media layers associated with lymphogtic in filtration and proliferation of vascular smooth muscle cells toward the intima, these lesions appear at 21 day from treated H2O2 in female pregnant rats. The study also remark hitopathological changes in placenta.
