This study was done to compare a new analgesic ketorolac with ibuprofen in post-operative and post-laparoscopy pain. A total of 40 patients were recruited for the study of which 20 were post-operative and 20 were post-laparoscopy cases. Medication was given over a period of 48 hours after surgery and a pain score based on subjective symptoms was monitored at fixed intervals after each dose. The analgesic efficacy of ketorolac was found to be comparable to that of ibuprofen and the drug was well tolerated in the doses used without any extra medication being required.
Tinospora cordifolia (Tc) is an Indian medicinal plant with proven immunomodulatory activity. This study was performed to elucidate its possible mechanism of action. We measured CFU-GM Cotony forming units of the granulocyte-macrophage series in serum of mice treated with Tc. We found that 10 days treatment with Tc (100 mg/ kg/d) induced a significant (p < 0.01) increase in the number of CFU-GM (255 +/- 49.32 vs 38.51 +/- 9.98) This suggests that activation of macrophages by Tc leads to increase in GM-CSF which leads to leucocytosis and improved neutrophil function.

Stress is known to depress the immune system severely. This study was done to evaluate whether surgical stress influenced polymorphonuclear (PMN) and monocyte functions in association with serum cortisol and the anxiety score as measured on the HARS Rating Scale. We found that surgery (irrespective of whether it was major or minor) significantly depressed PMN and monocyte functions and increased serum cortisol levels. PMN phagocytosis correlated significantly (p < 0.05) with the rise in serum cortisol. In spite of these changes, postoperative clinical recovery was uneventful. No major alterations in the HARS scores were noted pre and post operatively. This study demonstrates that surgical stress depresses the immune system with a concomitant rise in cortisol.
