Abstract
Neurotoxicity is a major obstacle to the effectiveness of cisplatin (CDDP) in cancer chemotherapy. In this process, oxidative stress and inflammation are considered to be the major mechanisms involved. The aim was to study the influence of protein quantity on some oxidative parameters in brain and lung of rats treated with cisplatin and N-Acetylcysteine (NAC). Four groups of Wistar rats (6 each one) were fed with a protein diet at 7% for 15 days. Thereafter, the groups were given either a unique dose of cisplatin® 5mg/kg or Acetylcysteine® 5mg/kg as follows: group 1 (control), NaCl 0.9% vehicle; group 2, Cisplatin; group 3, NAC; and group 4, NAC + Cisplatin. The animals were sacrificed, a sample of blood were used to measure blood triglycerides and glucose. The brain and lung were used to assay lipids peroxidation (TBARS), glutathione (GSH), serotonin metabolite (5-HIAA), catalase and the activity of Ca+2, Mg+2 ATPase, using validated methods. TBARS, H2O2 and GSH decreased significantly in cortex and cerebellum/medulla oblongata of groups treated with CDDP and NAC. Total ATPase showed a significant increase in the lung and cerebellum/medulla oblongata, while 5-HIAA depicted the same tendency in cortex of the same group of animals.
5-HIAA and ATPase increase during NAC and Cisplatin administration resulted in brain protection. This effect could even be more powerful when membrane fluidity is increased; thus, proving the efficacy of combined NAC and CDDP drug therapy, which appears to be a promising strategy for future chemotherapy in malnourished patients.
