Part Used : เมล็ดActivity : CARCINOGENESIS INHIBITIONSolvent/Active Compound : n-6 linoleic acid-rich corn oil (C-oil)Type of experiment : in vivoType of animal : ratType of study : -N(Total) : -N(Treatment) : -Sex : -Age : -Route : Oral administrationDose/Conc.(herb) : 10% corn oil plus 40 ppm indomethacin in their drinking waterDuration : 32 weeksType of interaction : PharmacodynamicsInteraction with drug : Indomethacin*/IndometacinDose/Conc.(drug) : indomethacin 40 ppm in the drinking waterResult : PositiveRemark : Result: For colon tumor, the multiplicity of adenomas was significantly decreased in the indomethacin + corn oil group compared with the corn oil alone group.Note : The animals were given a combined treatment comprised of a single i.p. administration of 100 mg/kg body weight N-diethylnitrosamine (DEN) at the commencement of the study, four i.p. administrations of 20 mg/kg body wt. N-methyl-nitrosourea (MNU) (on days 3, 6, 9 and 12), four s.c. administrations of 40 mg/kg body wt. 1,2-dimethylhydrazine (DMH) (on days 14, 18, 22 and 29), 0.05% N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN) in their drinking water for 2 weeks and 0.1% N-nitrosobis (2-hydroxypropyl) amine (DHPN) in their drinking water for 2 weeks during the initial four week period for wide spectrum initiation. Three days after completion of carcinogen exposure, test diets were given to the animals.
