1 Recent studies suggest that lead induces oxidative stress in various tissues. 2 Captopril ([2S]-1-[3-mercapto-2-methylpropionyl]-L-proline), an angiotensin-converting enzyme inhibitor, is a well-known antihypertensive agent and is also believed to function as an antioxidant. 3 In the present study the antioxidant effect of captopril on lead-induced oxidative stress was studied in Fischer 344 rats. Their liver, brain and kidneys were assayed for glutathione (GSH), glutathione disulfide (GSSG), malondialdehyde concentrations, and catalase activities. The results from animals treated with captopril were compared to results of control and lead-exposed non-treated groups. 4 The captopril-treated samples showed higher GSH:GSSG ratios in the liver, brain and kidneys, as well as slightly decreased malondialdehyde concentrations. The catalase activity was not significantly affected.

Ad Libitum

Breath ethane, O2consumption, and CO2 production were analyzed in 24-mo-old female Fischer 344 rats that had been fed continuously ad libitum (AL) or restricted 30% of AL level (DR) diets since 6 wk of age. Rats were placed in a glass chamber that was first flushed with air, then with a gas mixture containing 12% O2. After equilibration, a sample of the outflow was collected in gas sampling bags for subsequent analyses of ethane and CO2. The O2 and CO2 levels were also directly monitored in the outflow of the chamber. O2 consumption and CO2 production increased for DR rats. Hypoxia decreased O2consumption and CO2 production for the AL-fed and DR rats. These changes reflect changes in metabolic rate due to diet and [Formula: see text]. A significant decrease in ethane generation was found in DR rats compared with AL-fed rats. Under normoxic conditions, breath ethane decreased from 2.20 to 1.61 pmol ethane/ml CO2. During hypoxia the levels of ethane generation increased, resulting in a DR-associated decrease in ethane from 2.60 to 1.90 pmol ethane/ml CO2. These results support the hypothesis that DR reduces the level of oxidative stress.
