|Title:||Cancare-a herbal formulation inhibits chemically induced tumours in experimental animals|
|Authors:||Rajeshkumar, N V|
|Abstract:||Cancer chemopreventive potential of Cancare, a multi-herbal formulation on chemically induced tumours was studied by N-nitrosodiethylaminc (NDEA) induced hepatocarcinogenesis in rats and 20-methylcholanthrene (20-MC) induced sarcoma development in mice. Oral administration of Cancare was found to inhibit the liver tumour development induced by N-nitrosodiethylamine. Animals administered with NDEA had visible liver tumours by the end of 30' weeks and the liver weight was raised to 6.1 ± 1.4 g/ 100 g body wt. None of the animals treated with Cancare (150 mg/ kg) developed any visible liver tumours by this period and the liver weight was 3.0 ± 0.6 g/ 100 g body wt. γ-Glutamyl transpeptidase, a marker of hepatocellularcarcinoma, which was raised to 83.7 ± 8. 9 U/I in serum of NDEA treated group was reduced to 35.2 ± 6.1 U/1 by simultaneous administration of Cancare. Elevated levels of serum alkaline phosphatase, glutamate pyruvate transaminase, bilirubin, liver glutathione S-transferase, glutathione and γ-Giutamyl transpeptidase in the NDEA administered group was significantly reduced by Cancare administration. Cancare administration inhibited the sarcoma development and increased the life span of mice administered with 20-MC dose dependently. All animals m the control group developed sarcomas by 150'h day and dead by 174th day after 20-MC administration. Cancare administration (30 mg and 150 mg/kg) inhibited the sarcoma development (46.7 and 60%) as well as increased the life span (53.3 and 66.7%) as estimated on 240th day after 20-MC administration. The results are indicative of the chemopreventive potential of Cancare against chemically induced neoplasmas.|
