Inroduction and ObjectiveAnxiety is a respond of anorganism to a likely treat which can disturb the cellular homstasis. Serotonergic and cannabinoidergic systems contribute in many physiologic behaviors like anxiety. This study was done to investigate the effect of cannabinoidergic system on central amygdala and its interference with serotonergic system on anxiety in "Elevated Plus Maze"Materials and Methods:After a week resting , several doses of Arachidonile Cyclo Propyle Amide (ACPA) and selected Agonist of serotonergic receptore 1 (5-HT1) with commercial name of " CP94253 Hydrochloride" has been Microinjected into Central Amygdala of rat. The presence in Open Arms Time percent (OAT%) and the number of entrance into the open arms percent (OAE%) and locomotor activity (LA) was measured.Results: Injection of ACPA has no effect anxiety behaviors. Injection of high doses of agonist of serotonergic receptor has also got no effect of anxiety. microinjection of non effective dose of CP94253 Hydrochloride into Central Amygdala could suppres the anxyolitic effect of ACPA.Conclusion: Presynaptic cannabinoid receptore of CB1 could inhibit many neurotransmitters secration like serotonin and it seems that serotonin agonist could replace the inhibited neurotransmitter by ACPA. nsi-language: EN-US;mso-fareast-language:EN-US;mso-bidi-language:FA'>ACPAباشد Manuscript profile

Inroduction and Objective: Disinfectants, to destroy or disable pathogenic microorganisms such as bacteria, algae, viruses, etc. are used. Performance is a complex function of several variables, a disinfectant, such as the type and amount the material and the type and concentration of microorganisms, contact time, water quality, etc. So, in many cases it's best to choose an appropriate disinfectant, is an in vitro study. The aim of this study was to determine concentrations tolerated by potassium permanganate in fish carp and their impact on the flora of skin and tissue of the gills are.Material and Methods: Experiment with 5 treatments and a control (each with three replicates) at the Institute of International Sturgeon doctor Rasht Dadman phenomenon in the summer of 1391. Toxicity Testing in the 25-liter tank, two-thirds filled with water and were aerated for 24 hours, were conducted. weighted average of 10 fish per tank storage was 3.74± 0.45 g. The first, LC10, LC50, LC90 at 96 hours in residence on the 180 grass carp fish concentrations were determined by the logarithmic method. Within 96 hours of the end of the gill tissue was studied histologically.Results: The results showed that the gills after exposure in the presence of potassium permanganate phenomena such as congestion, adhesions secondary gill filaments and cell necrosis (low), hyperplasia, atrophy of primary and secondary fibers were seen clubbing. After 96 h of exposure to concentrations determined in order to evaluate in terms of total bacteria, CFU skin biopsy was performed. And results in skin samples treated 0.25 milligrams per liter compared with the other treatments and the control of bacteria were lower.ConclusionIn general we can say based on LC50 96h, this antiseptic is very toxic to fish carp with respect to the influence of physicochemical factors on the toxicity of these substances on fish, can be in different conditions will show different results.Visitors will be different.

Inroduction and Objective: Almost any type of stress, whether physical or neurogenic, causes increased secretion of cortisol from the adrenal. The connection between stress and the gut microflora have been showed by several studies and severely damaged gut microflora could cause stress and vise versa. Since Probiotics modulate the composition of the intestinal microflora , they plays an important role in ameliorating the side effects of stressMaterial and Methods: For this study, forty male wistar rats aged 12-14 weeks and weighed 110-130 gm was used. After a 2-week adaptation period, the rats were randomly divided into four group positive control, negative control (stress), trail 1 (probiotic) and trail 2 (probiotic with stress). Trail groups were administrated with 2×109 cells of Lactobacillus casei TD2, by oral gavage. Restraint stress was applied to the treated group for 15 minutes. After 21 days, rats were anesthetized with ether and blood samples were taken from heart. Then EIA kit is used for quantitative determination of corticosterone in plasmaResultsOur results showed that corticosterone level in positive group was significantly increased compare to negative control . It also became clear that receiving probiotics in second trial group caused a significant decrease in hormone concentration to 0.226 ± 0 005 mg/d compared to the positive control. Further examination of the results showed that the Trail 1 group had normal hormone levels compare to negative controlsConclusions:The results of these tests indicate that the probiotic Lactobacillus casei as a probiotic can reduce the negative effects of chronic stress and reduce corticosterone hormone levels of blood significantly Manuscript profile
