Abstract
In this study, we measured the concentration of some antioxidant substances in erythrocytes hemolysate, liver, kidney and brain in young and adult camels. It has been found that the activity of the antioxidant enzymes glutathione peroxidase (GSH-Px), catalase (CAT), superoxide dismutase (SOD) and the concentration of glutathione, ascrobic acid and α-tocopherol are high in both young and adult camels. GSH-Px and CAT activities were higher in adult camels than in the young and adult camels. no significant difference in the activity of SOD between young and adult camels was noticed. Glutathione was present in all tissues studied. Ascorbic acid was found to have significantly higher values in young camels. From this study it could be concluded that, as in other mammals, camel tissues contain a powerful antioxidant system. The liver has the highest contents of antioxidants and antioxidant enzymes indicating that it plays an important role in pro-oxidants detoxification. Age has a variable effect on the antioxidant system in camels.
Resumen
En el trabajo se miden las concentraciones de algunas sustancias antioxidantes en eritrocitos, hígado, riñón y cerebro de camellos jóvenes y adultos. Se ha encontrado que la actividad de los enzimas antioxidantes glutation peroxidasa (GSH-Px), catalasa (CAT), superóxido dismutasa (SOD) y la concentración de glutation, ácido ascórbico y alfa-tocoferol son elevadas tanto en los jóvenes como en los camellos adultos. La actividad glutation peroxidasa y catalasa es mayor en adultos que en jóvenes, mientras que no hay diferencias significativas en la superóxido dismutasa. El ácido ascórbico presentaba mayores valores en individuos jóvenes que en adultos. Los resultados permiten concluir que, como en otros mamíferos, los tejidos de camello presentan un poderoso sistema antioxidante. El hígado es el órgano que contiene may ores valores de sustancias y de actividad antioxidante, lo que indica su importancia en la detoxificación oxidativa.
