introduction: pain as a complex process in central nervous system (cns) has been studied by many researchers. pain is controlled by several cns pathways, one of the most important of which, is the descending noradrenergic system. this system begins from locus coeruleus (lc) nucleus in pons and ends in the spinal cord. in this research, the effect of pain induced by formalin was studied. methods...

Few studies have used Balb/c mice as an animal model for lung carcinogenesis. In this study, we investigated the effect of different doses of cigarette smoking in the urethane-induced Balb/c mouse lung cancer model. After injection of 3mg/kg urethane intraperitoneally, the mice were then exposed to tobacco smoke once or twice a day, five times a week, in a closed chamber. The animals were rando...
