Descripción : | The objective of the study is to determine the damage by oxidative stress induced by morphine in brain of rats fed with a protein-deficient diet. Twenty-eight malnourished male Wistar rats, 30 days old, were used in the study. The animals were divided into four groups of 7 rats per group. Group I received NaCl and the groups II; III and IV intraperitoneally received 3, 6 and 12 mg/kg of morphine sulphate, respectively, in a single dose. Animals were sacrificed and the levels of glutathione (GSH), dopamine, tryptophan and 5-hydroxyindole-3-acetic acid (5-HIAA) as well as, Na+/K+ ATPase and total ATPase activity in the brain were measured. Tryptophan levels and Na+/K+ ATPase activity showed non-significant changes in the experimental group. Levels of 5-HIAA decreased significantly (p =.03) in animals that received 12 mg/kg of morphine and in animals that received 3 mg/kg, levels of GSH and dopamine were found to have a significant decrease (p <.05), but a significant increase in the group that received 12 mg/kg of morphine (p <.05). Total ATPase activity increased significantly in the groups that received 3 mg/kg (p =.015) and 6 mg/kg (p =.0001) of morphine. The results show that malnutrition induces changes in cellular regulation and biochemical responses to oxidative stress caused by morphine sulphate. |
