Abstract

Background: the liver is a critical organ because it contains most of the accumulated metals where toxic effects can expected. Also, the lung is directly affected by receiving aluminum as aluminum silicate. Exposure of aluminum leads to production of free radicals that damage living organs and tissues. Aim of the work: this study aimed to evaluate the nucleic acid content in liver, lung and cerebellum tissues intoxicated by aluminum silicate (AlS) and the possible ameliorative effect of propolis extract (PP). Material and methods: Forty male albino rats (weighting 100-120 grams) were categorized randomly into four groups, ten rats on each group (n=10). The 1st group considered as the healthy control group. The 2nd group received 200 ml PP/kg b.wt., day after day by stomach gavage. The 3 rd group was injected intraperitoneally by 20 mg AlS/kg b.wt., twice weekly. The 4th group was treated with AlS in addition to PP as the same doses as in the 2nd and 3rd groups. After two months for each group. Liver, lung and cerebellum organs were harvested. Results: decreased body weight gain of rats was realized with weakly stained nucleic acids contents in liver, lung and cerebellum tissues that intoxicated by AlS. While, using the supplemented treatment (PP) at the same time with the induction of AlS compound showed an ameliorative effect on the nucleic acid contents. Conclusion: propolis has anti-oxidant by inhibiting AlS toxicity on nucleic acids in the different experimental organs of rats.
