Abstract:
Objective To observe the therapeutic effects of the co-administration of γ-aminobutyric acid (CABA), sodium dimercaptopropane sulfonate (Na-DMPS) and vitamin B6 in large doses on liver and heart of rats with acute tetramine intoxication, and compare their separate effects of either GABA or Na-DMPS alone with those of the triad combination. Method Thirty rats were randomized into control group (n = 6), tetramine intoxication without treatment group (n = 6), tetramine intoxication treated with GABA group (n = 6), tetramine intoxication treated with Na-DMPS group (n = 6) and tetramine intoxication treated with triad combination (GABA + Na-DMPS + vitamin B6, GNDV n = 6) group. Samples of blood, liver tissue and heart tissue of rats with acute tetramine intoxication were collected immediately two hours after medication with different drugs. Serum alanine aminotrasferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) were measured, and the pathological changes of liver tissue and heart tissue were observed under microscope. Results The symptoms of poisoning were apparently relieved and the latency for convulsion/muscular twitch were obviously delayed in poisoned rats treated with GABA, Na-DMPS and GNDV separately. Furthermore, combination group showed the latent period delayed longer than either GABA or Na-DMPS groups The GABA, Na-DMPS and GNDV significantly lowered the serum levels of ALT, AST, CK and CK-MB in rats with tetramine intoxication, and those serum levels of enzymes were lower in GNDV group than those in either GABA group or Na-DMPS group. However, there were no difference in those serum enzymes between GABA group and Na-DMPS group. Moreover, the intoxicated rats treated with combination treatment had the slightest pathological changes in liver and heart (GNDV < GABA or Na-DMPS). Conclusions The co-administration of γ-aminobutyric acid, sodium demercaptopropane sulfonate and vitamin B6 in large doses for the treatment of tetramine intoxication is a method of choice.
