We investigated the effect of ATP-MgCl_2 on myocardial hemodynamics and ultrastructure. In the in vitro study, left ventricular systolic and diastolic pressures and dp/dt values were significantly high in the ATP-MgCl_2 group beginning from 0.5 h of the reperfusion period. In the ATP-MgCl_2 group, at the end of the third hour, systolic and diastolic pressure values were 80.0 ± 6.2 and 75.2 ± 7.2 mmHg, while in the control group they were 18.4 ± 7.7 and 7.5 ± 6.8 mmHg (P < 0.05). In the ultrastructural analysis, myofibrillary damage was observed in both groups, but the mitochondrial pathologic changes were clearer in the control group. The electron microscopic score was 0.40 ± 0.061 in the ATP-MgCl_2 group and 1.2 ± 0.039 in the control group (P < 0.001). The hemodynamic and ultrastructural parameters of the specimens investigated in this study revealed that the usage of ATP-MgCl_2 may be beneficial in coping with ischemia-reperfusion damage. In the near future, with the help of more comprehensive studies, ATP-MgCl_2 is expected to be used routinely because of its potential benefits.

Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to investigate serum iron parameters, and copper and iron deficiency anemia in ewes infected with gastro-intestinal parasites. This study was conducted with 60 pregnant Akkaraman ewes. In the statistical analyses, values obtained from both parasite infected and uninfected ewes were compared. Significant decreases were observed in PCV (P < 0.05), Hb (P < 0.05), RBC (P < 0.05), total protein (P < 0.05), albumin (P < 0.05), globulin (P < 0.05), and MCHC (P < 0.01), and a significant increase was seen in the WBC value (P < 0.05) in the parasite infected group. Furthermore, the parasite infected group had lower serum Fe (P < 0.001), TS % (P < 0.001), and serum Cu (P < 0.01) levels, and had higher UIBC values (P < 0.05) compared to the values obtain from the uninfected group. Therefore, in addition to antiparasite drug treatment in parasite infected pregnant ewes, iron preparations should also be administered in order to treat iron deficiency.
