ABSTRACT
BACKGROUND: The incidence of skin cancers is rising gradually. The treatment of melanoma is also necessary to prevent the spread of cancer to other body organs. Scientific literatures have not documented any evidence of the antitumor potential of Ipomoea pes-caprae on melanoma. AIM OF THE STUDY: Explore in vivo antitumor potential of I. pes-caprae on melanoma cancer. MATERIALS AND METHODS: Petroleum ether (60°C-80°C), methanolic and aqueous extracts, and swaras prepared from the whole herb of I. pes-caprae were assessed for their antitumor activity. The extracts and swaras at doses of 25 and 50 mg/kg b. wt. were administered intraperitoneal along with chemo and radiotherapy for 40 days for exploring antitumor activity against melanoma cancer (B16F10) in male C57BL mice. The results obtained from tumor volume, and histopathological studies were compared with the control and dacarbazine used as a standard. RESULTS: Antitumor effect of I. pes-caprae extracts and swaras on melanoma cancer was found to be significant (P < 0.01) compared to normal control. The tumor volume inhibition against tumor-bearing mice, although differed from each other, was concentration dependent. Administration of plant extracts and swaras from the day 1 since tumor inducted. The induction of tumor was found delayed by 10-15 days and the tumor volume on the day 40 was similar to the Dacarbazine treatment used as a standard. CONCLUSION: The results obtained from the tumor volume and histopathological studies clearly revealed the antitumor potential of I. pes-caprae on melanoma cancer.
ABSTRACT
OBJECTIVE: To assess the In vivo antioxidFant and hepatoprotective activity of methanolic extract of Daucus carota (D. carota) seeds in experimental animals. METHODS: Methanolic extracts of D. carota seeds is used for hepatoprotection assessment. Oxidative stress were induced in rats by thioacetamide 100 mg/kg s.c, in four groups of rats (two test, standard and toxic control). Two test groups received D. carota seeds extract (DCSE) at doses of 200 mg/kg and 400 mg/kg. Standard group received silymarin (25 mg/kg) and toxic control received only thioacetamide. Control group received only vehicle. On the 8th day animals were sacrificed and liver enzyme like serum glutamic pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT) and alkaline phosphatase (ALP) were estimated in blood serum and antioxidant enzyme like superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GRD), glutathione peroxidase (GPX), glutathione-S-transferase (GST) and lipid peroxidation (LPO) were estimated in liver homogenate. RESULTS: A significant decrease in SGPT, SGOT and ALP levels was observed in all drug treated groups as compared to thioacetamide group (P < 0.001) and in case of antioxidant enzyme a significant (P < 0.001) increase in SOD, CAT, GRD, GPX and GST was observed in all drug treated groups as compared with thioacetamide group. But in case of LPO a significant (P < 0.001) reduction was observed as compared to toxic control group. CONCLUSIONS: DCSE has contributed to the reduction of oxidative stress and the protection of liver in experimental rats.

Filariasis is result of parasitic infection caused by three specific kinds of round worm. Lymphatic filariasis is found in under developed region of South America, Central Africa, pacific and Caribbian. It has been found for centuries, with main symptoms as elephant like swelling of the arms, legs and genitals. It is estimate that 120 millions peoples in the world have lymphatic filariasis. The spread of diseases and the challenge encountered in its management are discussed along with a review on drugs against filariasis in this article. Detail on clinical effect of drugs on the infection, safety profile, status in clinical practices and drug resistances are also covered.
