To study anti-inflammatory and analgesic activities in swiss albino mice, two schiff bases namely acetophenone semicarbazone (ASC) and benzophenone semicarbazone (BSC) were synthesized and characterized. Methods: Two doses of the test compounds 25 and 50 mg/kg (p.o) for each were selected throughout the research work. The anti-inflammatory activity of the test compounds was determined by 'carragenan induced mice paw edema inhibition' method. The analgesic activity was determined by both, 'acetic acid induced writhing' and 'tail immersion' methods. All such data were compared with standard drugs at the dose of 10 mg/kg (p.o.). Results: Both ASC and BSC have showed positive effects as anti-inflammatory and analgesic agents. Anti-inflammatory and analgesic activities of the test compounds at 50 mg/kg (p.o.) were quite comparable to those of standard drugs at 10 mg/kg (p.o.). Conclusion: Both ASC and BSC can be considered as potent anti-inflammatory and analgesic agents.

The research study was conducted to determine the antitumor effect of the flower of Alangium salvifolium (crude extract and diethylether fractions) against Ehrlich Ascites Carcinoma (EAC) in mice at the doses of 10 mg kg-1 body weight intraperitoneally. Extract/fractions was administered for nine consecutive days. Twenty-four hours of last dose and 18 h of fasting, the mice were sacrificed and antitumor effect was assessed by evaluating tumor volume, viable and nonviable tumor cell count, tumor weight and hematological parameters of EAC bearing host. Significant (p<0.001) increases of survival times 30±0.96 and 25±0.40 days for crude extract and diethylether fraction of the A. salvifolium (10 mg kg-1) treated tumor bearing mice, respectively were confirmed with respect to the control group (20±0.13 days). The extract/fraction also decreased the body weight of the EAC tumor bearing mice. Hematological studies reveal that the heamoglobin (Hb) content was decreased in EAC treated mice whereas restoration to near normal levels was observed in extract treated animals. There was a significant (p<0.001) decrease in RBC count and increase in WBC counts in extract/fraction treated animals when compared to EAC treated animals. From the result it was showed that the extract has significant anticancer activity and that is comparable to that of Bleomycin.

The present study was designed to investigate the antioxidant and anti neoplastic activities of Ocimum sanctum Linn. (OS) leaves. Antioxidant potential of the OS extract was evaluated in vitro by DPPH (1, 1diphenyl-2-picrylhydrazyl) and NO (Nitric Oxide) scavenging assay and reducing power assay method. OS extract showed prominent scavenging activity in all the methods with IC50 value of 16.39±0.31 and 16.20±0.33 μg mL-1 for DPPH and NO assay method, respectively. In reducing power assay, OS extract also showed significant (p<0.001) activity. In addition, total phenolic and flavonoid content and total antioxidant capacity were also determined. The anti neoplastic effect of the leaves of OS against Ehrlich Ascites Carcinoma (EAC) in mice at the doses of 50 mg kg-1 body weight intraperit one ally. Significant (p<0.001) increases of survival times 33±1.81 days for crude extract of the (50 mg kg-1) treated tumor bearing mice were confirmed with respect to the control group (20±0.12 days). Hematological studies reveal that the Heamoglobin (Hb) content was decreased in EAC treated mice whereas restoration to near normal levels was observed in extract treated animals. There was a significant (p<0.001) decrease in RBC count and increase in WBC counts in extract/fraction treated animals when compared to EAC treated animals. From the result it was showed that the extract has significant antioxidant as well as anti neoplastic activity.
