ABSTRACT

SUMMARY:

Acrylamide (ACR) is a cytotoxic and carcinogenic material. It is a product of a Maillard reaction during the cooking of many types of fried fast food, e.g. potato chip fries, and chicken nuggets. ACR has a severe toxic effect on different body organs. This study investigates the hepatotoxic effect of ACR, and the protective effect of ascorbic acid and silymarin. For this purpose, forty adult, male, albino rats were divided into four groups and received the following treatments for fourteen days Group I (the control) normal saline; Group II ACR only; Group III ACR and ascorbic acid; and Group IV ACR and silymarin. Under a light microscope, the liver from rats treated with ACR only presented disturbed liver architecture, degenerated hepatocytes, reduced glycogen contents, congested central vein, and increased collagen fibres with areas of fibrosis. Immunohistochemical examination revealed an increased mean number of CD68-, and α-SMA-positive cells. This indicates the presence of large numbers of stellate macrophages (Kupffer cells) and Hepatic stellate cells (HSCs). The combination of ACR with either ascorbic acid or silymarin resulted in less hepatic degeneration, less fibrosis and fewer CD68 and α-SMA positive cells compared to the ACR only group. In conclusion, treatment with silymarin or ascorbic acid along with ACR appears to alleviate ACR-induced hepatotoxicity with more protection in silymarin treated rats.
RESUMEN
RESUMEN La acrilamida (ACR) es un material citotóxico y cancerígeno. Es producto de la reacción de Maillard durante la cocción de muchos tipos de comida rápida y frita, por ejemplo papas fritas y nuggets de pollo. ACR tiene un efecto tóxico severo en diferentes órganos del cuerpo. Este estudio investigó el efecto hepatotóxico del ACR y el efecto protector del ácido ascórbico y la silimarina. Con este fin, cuarenta ratas albinas machos adultas se dividieron en cuatro grupos y recibieron los siguientes tratamientos durante catorce días Grupo I (control), solución salina normal; Grupo II, solo ACR; Grupo III, ACR y ácido ascórbico; y Grupo IV, ACR y silimarina. Bajo microscopio óptico, el hígado de ratas tratadas con ACR solo presentó alteración de su arquitectura, entre ellos hepatocitos degenerados, contenido reducido de glucógeno, vena central congestionada y aumento de fibras de colágeno con áreas de fibrosis. El examen inmunohistoquímico reveló un aumento del número medio de células CD68 y α-SMA positivas. Esto indica la presencia de un gran número de macrófagos estrellados (células de Kupffer) y células estrelladas hepáticas (HSC). La combinación de ACR con ácido ascórbico o silimarina resultó en menos degeneración hepática, menos fibrosis y menos células positivas para CD68 y α-SMA en comparación con el grupo de ACR solo. En conclusión, el tratamiento con silimarina o ácido ascórbico junto con ACR parece aliviar la hepatotoxicidad inducida por ACR.
