Abstract

Purpose: In our study, after applying a single dose of 612 cGy irradiation, we aimed to observe the role of free radicals on tissue damage in the kidney caused by radiation by measuring NO level, Na/K-ATPase activity and TBARS amount which is an indicator of free radical damage. On the other hand we investigated whether the tissue damage can be prevented by vitamin A or not. Materials and methods: This study was performed on three groups: 1. Control group 2. The group to which irradiation was administrated 3. The group which was given radiation + vitamin A. The irradiation group of animals were given a single dose of gamma irradiation at a sublethal dose. In the group which was administrated both irradiation + vitamin A, vitamin A was given for two days prior to irradiation. The amount of NO was measured by ESR spectroscopy, Na/K-ATPase and TBARS were measured by spectrophotometry. Results and conclusions: As a result of radiation mediated tissue damage in the kidney, we observed a NO loss, a decrease in Na/K-ATPase activitiy and an increase in TBARS amount. Although the administration of vitamin A before radiation, did not have any effect on NO loss and decrease in Na/K-ATPase.
