Cyclophosphamide induced oxidative stress, lipid per oxidation, apoptosis and histopathological changes in rats: Protective role of boron.

Background: Cyclophosphamide (CP) is an alkylating chemotherapeutic drug used in the treatment of many types of cancer. However, as with other chemotherapeutic drugs, the use of CP is limited by the damage to healthy tissues such as testes, bladder and liver as well as cancerous tissue. Boron (B) is a trace element with many biological properties such as antioxidant, anti-apoptotic and anti-lipid per oxidation.

The effects of lycopene on hepatic ischemia/reperfusion injury in rats.

There is a very little information about the protective effect of lycopene (LYC) against hepatic ischemia-reperfusion injury. The present study was designed to examine the possible protective effect of the strong antioxidant and anti-inflammatory agent, LYC, on hepatic ischemia/reperfusion injury. For this purpose, rats were subjected to 45 min of hepatic ischemia followed by 60 min of reperfusion period.

Protective effects of N(G)-nitro-L-arginine methyl ester and metallothioneins on excess nitric oxide toxicity in trinitrobenzene sulfonic acid-induced rat colitis.

Objective: To evaluate the protective effects of N(G)-nitro-L-arginine methyl ester (L-NAME) and metallothioneins on excess nitric oxide toxicity in trinitrobenzene sulfonic acid (TNBS)-induced rat colitis.

Study Design: In this study, 70 rats were assigned to 7 groups of controls, and colitis was induced with 120 mg/kg TNBS, 35 mg/kg L-NAME, and 1 and 2 mg/kg metallothionein 1 (MT1) and metallothionein 2 (MT2), respectively. A day after the administration of TNBS, L-NAME, MT1 and MT2 were given intraperitoneally for 3 days to the experimental groups.

Seleno L-methionine acts on cyclophosphamide-induced kidney toxicity.

The anticancer drug cyclophosphamide (CP) has nephrotoxic effects besides its urotoxicity, which both in turn limit its clinical utility. The nephrotoxicity of CP is less common compared to its urotoxicity, and not much importance has been given for the study of mechanism of CP-induced nephrotoxicity so far. Overproduction of reactive oxygen species (ROS) during inflammation is one of the reasons of the kidney injury.

Protective effect of seleno-L-methionine on cyclophosphamide-induced urinary bladder toxicity in rats.

Cyclophosphamide (CP) is a widely used antineoplastic drug, which could cause toxicity of the normal cells due to its toxic metabolites. Its urotoxicity may cause dose-limiting side effects like hemorrhagic cystitis. Overproduction of reactive oxygen species (ROS) during inflammation is one of the reasons of the urothelial injury.
