All of the sulfhydryl-containing antioxidants used in this study exhibited a significant role in attenuating intestinal I/R injury; however, the outcome of the LA-treated group was significantly marked than that of the others.

Ondansetron appeared to be superior to metoclopramide-diphenhydramine in the control of emesis induced by chemotherapy regimens containing cisplatin. The results of the present prospective randomized study indicate that ondansetron is a useful anti-emetic in the treatment of chemotherapy-induced emesis.

The aim of this study was to evaluate the presence and degree of preclinical atherosclerosis in pups of pregnant rats exposed to cigarette smoke. Abdominal aorta examined for atherosclerotic lesions and intimal medial thickness of the abdominal aorta was measured by image analysis. The study groups showed endothelial cellular losses, marked intimal injuries, elastic fiber damages, mononuclear cellular infiltration, and irregularities in internal elastic membrane, with pronounced damages as integrity losses and local fragmentations. The results provide evidence for development of an atherosclerotic process in the neonatal period, even in prenatal stage, long before the formation of smoke-related cardiovascular diseases.

Cyclooxygenase-2 and endothelial nitric oxide (NO) synthase enzymes may have a role in developing preclinical atherosclerosis. Designed groups were as follows: smoke exposed rats before and during pregnancy, only before pregnancy, and controls. Cross-sectional samples of abdominal aorta were examined immunohistochemically. Cyclooxygenase-2 and eNOS expression was evaluated semi-quantitatively through staining extent (focal, diffuse) and staining intensity. Diffuse COX-2 expression was detected in study groups. Endothelial NO synthase expression was diffuse in study groups. COX-2 and eNOS may contribute to the formation of preatherosclerotic lesions in offspring of rats exposed to cigarette smoke through inflammatory response.
