Introduction: Chlorpyrifos (CPF), a phosphorothionate chlorinated organophosphate (OP) insecticide is widely used in agriculture and public health. Like other OP insecticides, its main mechanism of toxicity is the inhibition of acetylcholinesterase (AChE) leading to cholinergic syndrome. Since toxicity occurs at doses that do not inhibit AChE or long after its restoration, other mechanisms including the induction of oxidative stress have been widely implicated. The present study was aimed at evaluating the mitigating effect of vitamin C on CPF-induced hepatocellular injury in Wistar rats. Methods: Twenty adult male Wistar rats were divided into 4 groups of five animals in each group. The four groups were exposed by gavage to soya oil (2 ml/kg), vitamin C (100 mg/kg), CPF (10.6 mg/kg~1/8th LD50) and vitamin C (100 mg/kg) + CPF (10.6 mg/kg; 30 min later), respectively for 17 weeks. The sera obtained from blood samples collected from the animals were analysed for the levels of total proteins, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), g-glutamyl transferase (GGT) while globulin concentration and albumin/globulin ratio were calculated. The liver homogenate was evaluated for the levels of malonaldehyde (MDA), superoxide dismutase (SOD) and catalase (CAT), and histological changes. Results: The study showed that CPF altered the levels of the serum hepatic enzymes, hepatic MDA SOD and CAT, in addition to inducing hepatocellular degeneration. All these parameters were alleviated by pretreatment with vitamin C. Significance: CPF-induced hepatocellular injury which was partly due to oxidative changes was mitigated by vitamin C partly due to its antioxidative activity.

Chlorambucil (4-[4-[bis(2-chloroethyl)amino]phenyl]butanoic acid) is an alkylating agent, indicated in chronic lymphocytic leukaemia. Kolaviron (KV), a biflavonoid complex fromGarcinia kola,and L-ascorbic acid (AA) are known to protect against oxidative damagein vivo. This study evaluates the protective capacity of KV and AA on chlorambucil-induced oxidative stress in the testes of rat. Twenty male Wistar rats (180–200 g) were randomized into four groups: I: control, II: chlorambucil (0.2 mg/kg b.w.), III: 0.2 mg/kg chlorambucil and 100 mg/kg KV, and IV: 0.2 mg/kg chlorambucil and 100 mg/kg AA. After 14 days of treatments, results indicated that chlorambucil caused significant reduction (P<0.05) in testicular vitamin C and glutathione by 32% and 39%, respectively, relative to control. Similarly, activities of testicular GST, SOD, and CAT reduced significantly by 48%, 47%, and 49%, respectively, in chlorambucil-treated rats relative to control. Testicular MDA and activities of ALP, LDH, and ACP were increased significantly by 53%, 51%, 64%, and 70%, respectively, in the chlorambucil-treated rat. However, cotreatment with KV and AA offered protection and restored the levels of vitamin C, GSH, and MDA as well as SOD, CAT, GST, ACP, ALP, and LDH activities. Overall, kolaviron and L-ascorbic acid protected against chlorambucil-induced damage in the testes of the rat.

Introduction.Pulmonary contusions can cause a progressive inflammatory response. Activation of TNF-α cytokines and reactive oxygen species (ROS) can cause pulmonary cell death. Antioxidants can have the potential to neutralize ROS. The purpose of this study is to determine the effectiveness of antioxidant administration in maintaining pulmonary cell function in wistar rats that have been induced to experience pulmonary contusions through caspase-3 levels. Methods.This study was an in vivo experimental study conducted on thirty male wistar rats and divided into five groups (n = 6): control, pulmonary contusion + asthaxanthine 5 mg/kgBW, pulmonary contusion + vitamin C and E 50 mg/kgBW, pulmonary contusion + vitamin C and E 100 mg/kgBW, pulmonary contusion + vitamin C and E 200 mg/kgBW. The value of Caspase-3 is evaluated by the IHC. All data analyzes used SPSS 18. Results. Low doses of antioxidants have the potential to reduce pulmonary cell death in wistar rats induced by pulmonary contusions.Conclussion. Vitamin C and E effective to reduce polmonary cell death in pulmonary contusion.Keywords: antioxidants, vitamin C, vitamin E, pulmonary contusions animal model, apoptosis, caspase-3
