The influence of adriamycin and adriamycin-radiation combinations on posttreatment proliferative activity of the mouse jejunum was examined by measuring [3H]thymidine incorporation. Single doses of 5 or 10 mg/kg produced a transient reduction in the proliferative activity, while 1 mg/kg had little effect. After 10 mg/kg, there was a rapid decrease in the number of mitotic figures, followed by a...

The purpose of this study was to examine the anxiety-related effects of acute and repeated amphetamine administration using the elevated plus maze (EPM) and light/dark box tests in mice. D-amphetamine (2 mg/kg ip, 30 min after injection) had a significant anxiogenic effect only in the EPM test, as shown by specific decreases in the percentage of time spent in the open arms as well as in the per...

Problem statement: Some reports showed the teratogenic effects of sodium valproate can be prevented by application of antioxidant drugs and stimulation of the maternal immune system. Therefore, in this study, the prophylactic effect of melatonin on teratogenic effects of sodium valproate was compared. Approach: This study was performed on 31 pregnant rats that were divided into five groups. Con...

Article history: Received: 19 June 2013 Accepted: 21 Aug 2013 Available online: 14 Oct 2013 ZJRMS 2014; 16(12): 59-64 Background: The liver plays a central role in insulin-like growth factor (IGF) system homeostasis. We examine the protective aerobic training on the IGF system following doxorubicin (DOX) induced hepatotoxicity. Materials and Methods: In this experimental study 48 Wistar male ra...

Dextromethorphan, a noncompetitive blocker of the N-methyl-D-aspartate (NMDA) type of glutamate receptor, at 45, 60 and 75 mg/kg, ip doses induced a behavioural syndrome characterised by reciprocal forepaw treading, lateral head-weaving, hind-limb abduction and flat body posture. Such type of behavioural syndrome is induced by 8-hydroxy-2- (di-n-propylamino) tetralin (8-OH-DPAT) by directly sti...

Sleep deprivation can lead to various alterations at physiological and psychological levels such as EEG changes, metabolic changes, irritation, blurred vision, memory lapses, hallucinations, psychosis and can even lead to death. Treatment still remains a challenge as hypnotics are associated with side effects. The objective of the present study was to investigate the protective effects of melat...

BACKGROUND Neuropathic pain is a chronic pain due to disorder in the peripheral or central nervous system with different pathophysiological mechanisms. Current treatments are not effective. Analgesic drugs combined can reduce pain intensity and side effects. Here, we studied the analgesic effect of nimesulide, nefopam, and morphine with different mechanisms of action alone and in combination wi...
