OBJECTIVE
The present study has aimed to evaluate chemopreventive potential of d-carvone on oxidative stress markers, biotransforming enzymes, incidence of colonic polyps and aberrant crypt foci (ACF) in 1,2-dimethylhydrazine (DMH)-induced experimental colon carcinogenesis.
METHODS
Rats were
Ulcerative colitis (UC) is an intractable ailment, in which may chronic inflammations/ulcerations may develop in the mucosal lining of the colon with multiple recurrences. Various drugs such as steroids, immunosuppressants, and antibiotics are extensively used to treat UC. The patients suffer from
d-Carvone occurs naturally in caraway and dill seeds and in many essential oils; it has been used as a carminative and in perfumes and soaps. Toxicity and carcinogenesis studies were conducted by administering d-carvone (approximately 96% pure) in corn oil by gavage to groups of male and female
The structural integrity and excellent immune system of the skin makes it a protective covering, inspite of its exposure to hazardous compounds. In the present study, the chemopreventive efficacy of D-carvone was studied in 7, 12-dimethylbenz[a]anthracene (DMBA) induced skin carcinogenesis. DMBA (25
Naturally occurring compounds belonging to two chemical groups were studied for their capacities to inhibit N-nitrosodiethylamine (NDEA)-induced carcinogenesis in female A/J mice. One group consists of organosulfur compounds found in Allium species, including garlic, onions, leeks, and shallots, and
Previously, we developed a 30-day transformation assay (focus inhibition, FIA) of rat tracheal epithelial (RTE) cells to identify cancer preventive agents. This study reports nuclear density (ND) as a morphometric biomarker for efficacy evaluation of at an early stage before transformed foci appear.
