objective: the present study was designed to investigate the putative antidepressant effects of crocin and crocetin, two major active ingredients of crocus sativus l. (saffron) using mice in two different regimens of acute and sub-acute administration. material and methods: in acute treatment, antidepressant-like activities of crocin and crocetin (10, 20 and 40 mg/kg, i.p.) were evaluated using...

OBJECTIVE Continuously administered insulin is limited by the need for frequent blood glucose measurements, dose adjustments, and risk of hypoglycemia. Regimens based on glucagon-like peptide 1 (GLP-1) could represent a less complicated treatment alternative. This alternative might be advantageous in hyperglycemic patients hospitalized for acute critical illnesses, who benefit from near normogl...

Contents of inorganic elements are very important traits in plants. Some of elements have causal effects on plant growth. Their effects on plant metabolism and therefore quality and quantity of essential oils is crucial. Thus, to obtain relatively good results, different parts of Rosa damascena Mill. genotypes were analyzed. Plants were collected from different provinces including Tehran, East ...

The reinforcing effects of D(1-like) and D(2-like) agonists, and their capacity to modify cocaine self-administration, were compared in rats with extensive cocaine self-administration experience. Cocaine (0.01-1.0 mg i.v.) dose-dependently maintained responding under a fixed ratio (FR) 5 schedule of reinforcement, and an inverted U-shaped function characterized the relationship between unit dos...
