Damaging effects of reactive oxygen species on living systems are well documented. They include oxidative attack on vital cell constituents. Chronic ethanol administration is able to induce an oxidative stress in the central nervous system. In the present study, 16-18 week-old male albino rats of Wistar strain were exposed to different concentration of ethanol for 4 weeks. This exposure showed profound effect on body weight. Ascorbic acid level; and activities of alkaline phosphatase and aspartate transaminase in the brain are dependent on the concentration of ethanol exposure. Chronic ethanol ingestion elicits statistically significant increase in thiobarbituric acid reactive substances level and decrease in gluatathione level in the brain. It reduces superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase activities in a dose dependent manner. However, histological examination could not reveal any pathophysiological changes. Therefore, we conclude that biochemical alterations and oxidative stress related parameters respond early in alcoholism than the histopathological changes in brain.

Transitional carcinomas are extremely rare in the fallopian tube. A 41-year-old premenopausal lady presented with colicky abdominal pain and was found to have a left-sided pelvic mass on examination. In view of the elevated CA-125 and imaging findings suggestive of ovarian mass, she underwent staging laparotomy. Pathological examination confirmed a primary transitional cell carcinoma of the left fallopian tube. Review of available literature suggested that the primary transitional cell carcinoma is probably less aggressive compared to classical adenocarcinoma of the fallopian tube, and it has to be distinguished from the recently recognized entity, parafallopian tube transitional cell carcinoma.

Background: Interest in translational studies aimed at investigating biologic markers in predicting response to primary chemotherapy (PCT) in breast cancer has progressively increased. We conducted a pilot study to evaluate feasibility of evaluating biomarkers of response to PCT at one & 21 days after first cycle.

This study demonstrates MVD as detected by CLEC14A in EOC. Treatment with chemotherapy reduces tumor blood vessels significantly. We suggest that CLEC14A may be a more specific endothelial marker to assess tumor angiogenesis.
