Tamrabhasma (TMB), an Indian indigenous preparation of copper, was studied for its effects on factors related to rat gastric mucosal resistance. Rats of either sex treated with TMB (2.5 mg/kg po, twice daily for 3 days) showed (i) increased mucosal sialomucin and fucose contents; (ii) decreased gastric juice DNA and protein; and (iii) no change in DNA and the incorporation of [3H]-thymidine in to mucosal cell DNA. aspirin treatment decreased both the sialomucin and fucose contents, and increased DNA and incorporation of [3H]-thymidine in to mucosal cell DNA. However, aspirin increased gastric juice DNA and protein contents. Since gastric juice DNA and the incorporation of [3H]-thymidine into mucosal cell DNA indicate the rate of mucosal shedding and cell proliferation, the results indicate ways in which TMB may increase gastric mucosal resistance to damage.
