  Objetivo. El objetivo de este estudio ha sido determinar el efecto protector del ácido p-cumárico (p-CA) contra la hepatotoxicidad, nefrotoxicidad y neurotoxicidad inducida por tolueno en ratas. Materiales y métodos. Se utilizaron un total de 32 ratas macho Sprague-Dawley, 8 en cada grupo. Se formaron 4 grupos: el de control, tolueno, p-CA y tolueno + p-CA. Los animales del grupo de control, el grupo de tolueno y el grupo de p-CA recibieron NaCl al 0.9%, 0.9 mg/kg de peso corporal de tolueno y 100 mg/kg de peso corporal de p-CA por vía oral durante 21 días, respectivamente. Resultados. En este estudio, se determinó que hubo aumentos significativos en las actividades de ALT y AST, y los niveles de creatinina en el grupo inducido por tolueno en comparación con el grupo de control. Además, hubo una disminución en las actividades de GSH-Px y los niveles de GSH, y un aumento en los niveles de MDA en comparación con el grupo de control. Sin embargo, en el grupo de tolueno + p-CA, se observaron disminuciones significativas en las actividades de las aminotransferasas, niveles de creatinina y MDA, y aumentos significativos en las actividades de GSH-Px y los niveles de GSH en comparación con el grupo de tolueno. Conclusiones. Se ha determinado que el p-CA tiene un efecto protector contra la hepatotoxicidad, nefrotoxicidad y neurotoxicidad inducidas por el tolueno.

  Objective. The aim of this study was to determine the protective effect of p-coumaric acid (p-CA) against toluene-induced hepatotoxicity, nephrotoxicity and neurotoxicity in rats. Materials and methods. A total of 32 Sprague-Dawley male rats, 8 in each group, were used. 4 groups were formed as control, toluene, p-CA and toluene+p-CA. Animals in the control group, toluene group and p-CA group were given 0.9% NaCl, 0.9 mg/kg b.w toluene and 100 mg/kg b.w p-CA orally for 21 days, respectively. The animals in toluene+p-CA group were received p-CA for 3 days and from day 4, toluene and p-CA were applied together daily until day 25. On the 25th day, the study was terminated, blood and tissue samples were collected. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatinine levels in serum, glutathione peroxidase (GSH-Px) activity and malondialdehyde (MDA) and glutathione (GSH) levels in the tissue samples were determined. Results. In this study, it was determined that there were significant increases in ALT and AST activities, and creatinine levels in toluene-induced group compared to control group. Moreover, there was a decrease in the GSH-Px activities and GSH levels, and an increase in the MDA levels compared to the control group. However, in the toluene+p-CA group, significant decreases in aminotransferases activities, creatinine and MDA levels, and significant increases in GSH-Px activities and GSH levels were determined compared to the toluene group. Conclusions. It has been determined that p-CA has a protective effect against toluene-induced hepatotoxicity, nephrotoxicity and neurotoxicity.
