ABSTRACT
This experiment was performed to evaluate the morphological responses of the gastric parietal cells of mouse inoculated with Ehrlich carcinoma cells, following administration of Bacillus Calmette -Guerin (BCG) or acriflavine -guanosine composition (AG60, Taerim Pharm. Co. Seoul, Korea). In the experimental groups, each mouse was inoculated with 1 X 10(7) Ehrlich carcinoma cells subcutaneously in the inguinal area. From next day, 0.2 ml of saline, BCG (0.03 X 10(8) ~0.32 X 10(8) CFU) or AG60 (30 mg/kg) was injected subcutaneously to the animals every other day. Animals were sacrificed on the 14th day from the first injection. Pieces of the tissue were taken from the stomach, prefixed with 2.5% glutaraldehyde -1.5% paraformaldehyde, followed by post -fixation with 1% osmium tetroxide. The ultrathin sections stained with uranyl acetate and lead citrate were observed with a JEM 100CX -II electron microscope. In the experimental control, the BCG and the AG60 treated groups, most parietal cells showed reduced lumenal spaces of the intracellular canaliculi, since microvilli of intracellular canaliculi were very irregularly shaped and crowed with each other. And in the BCG and the AG60 treated mice, myelin figures, lysosomes and multivesicular bodies in the parietal cells were observed more frequently than in those of the experimental control ones. In the BCG treated rats, membranes of the tubulovesicles of the parietal cells were disintegrated, but the similar changes were not observed in the AG60 treated mice,. Above results suggest that the BCG treated animals inoculated with Ehrlich carcinoma cells might suffer from reduced acid secretion of the parietal cell, since the disintegration of the tubulovesicular membranes in the parietal cells are occurred following injections. Whereas AG60 dose not affect remakably defect on the parietal cells.
