Introduction: According to the important role of Nitric oxide (NO) in many biological processes in cells and tissues, in this study we examined the inhibitory effects of L-NAME on weight and histology of a pregnant rat kidney. Materials and Methods: 24 Wistar rats weighing 200- 250 gr with a mean age of 8 weeks upon observing vaginal plaque that has been considered as day zero of pregnancy were divided in 3 groups of 8. Except the control group the remaining groups received normal saline (1mg/kg/ip), L-NAME (1 mg/kg/ip) during 3, 4 and 5th days of pregnancy. On the 18th day of pregnancy the rats were anesthetized by ether and via laparotomy the kidneys were removed. Kidneys fixed in 10% formalin and after tissue sample preparation, general (H + E) staining was performed. Finally the Histomorphological changes were studied by light microscopy. Findings:Despite the increasing in weight of the L-NAME group, There was no significant differences between groups (P<0.01) but in L-NAME group were observed disorder of the cortex and capsule of a kidney, immune cell infiltration, and congestion blood vessels. Discussion &Conclusion: Results of this study showed that L-NAME in pregnancy can cause damage in kidney tissue via decreasing levels of NO. Keywords: Kidney, Nitric oxide, L-NAME
