teucrium polium l. (lamiaceae) is used in the traditional medicine of iran for the treatment of disorders of the gastrointestinal tract. the essential oil from the aerial parts of t polium was assessed for antispasmodic activity and compared with the effect of atropine and dicyclomine. acetylcholine and kc i were used for induction of contraction on rat isolated ileum. teucrium polium essential...

Both aging and age-associated neurodegenerative diseases are related with various degrees of behavioral impairments, and among the prime candidates responsible for producing the neuronal changes mediating these behavioral deficits, appear to be free radicals and the oxidative agents which they generate. Free radicals such as vit. E may be important factors in maintaining neuronal integrity and ...

Introduction:The hippocampus is one for the major centers of learning and memory. Role of the opioid system has been investigated and on the other hand receptors related to this system such as mu-opioid receptors (MOR) are extended in the hippocampus. In this study the effect of Naloxone administration as a mu opioid receptor antagonist on passive avoidance memory in adult male rats was i...

objective(s): the aim of the present study is to determine the effect of chloramphenicol (cap) on rat liver and small intestine. effect of phenobarbital (pb) on cap toxicity was also investigated.   materials and methods:   rats were received cap at doses of 0, 200, 400 and 600 mg/kg. another group was pretreated with 80 mg/kg pb 30 min prior to administration of various doses of cap. the exper...

background: the study was performed to investigate the effects of morphine dependency and morphine withdrawal on the reproductive system of adult male rat(wistar).  methods: 32 adult male rat divided into 5 groups. animals in the control group (n=8) received normal saline (1ml/kg) twice daily subcutaneously for 30 consecutive days. animals in dependent group (n=8) received morphine (10mg/ml/kg)...

Morphine’s effects on learning and memory processes are well known to depend on synaptic plasticity in the hippocampus. Whereas the role of the hippocampus in morphine-induced amnesia and state-dependent learning is established, the biochemical and molecular mechanisms underlying these processes are poorly understood. The present study intended to investigate whether administration of morphine ...
