Aim & Objective. Artemisia dracunculus L. (Tarragon) species have been used as a traditional medicine. The present study was designed to evaluate the nociceptive and anti-inflammatory effects of A. dracunculus L. leaf aqueous extract on fructose drinking water (FDW) in male rats. Materials & Methods. Forty-eight Wistar-albino male rats weighing 200–250 g were divided into control (C), control extract (CE), FDW, and FDWE groups (n = 12). Group C did not receive any agents; Group CE did 100 mg/kg A. dracunculus L. aqueous extract on a daily basis for duration of four weeks. FDW Group received fructose drinking water (10%, weight/volume) but did not receive any agents during trial period. FDWE group received 100 mg/kg A. dracunculus L. aqueous extract during trial period. At the end of experiment, a biphasic pain response was induced following interplanetary injection of formalin (50 µL, 1%). Obtained data were analyzed using SPSS software version 17 and using ANOVA and Tukey post hoc tests. Results were expressed as mean ± SE. Statistical differences were considered significant at P < 0.05. Results. Our findings revealed that acute and chronic pain scores in FDW group are significantly higher than other ones and A. dracunculus L. aqueous extract causes significant decreasing of this parameter in FDWE group (P < 0.001). Moreover, IL6 and TNF values in this group were significantly decreased compared to FDW group (P < 0.05). Conclusion. Results in the present study show that FDW causes the pain response score to increase and cause proinflammatory cytokines in rat model but A. dracunculus L. leaf aqueous extract improves values of these parameters.
Background: Artemisia are various groups of plants which are used as an herbal medicine in all countries; the present study was designed to evaluate the effects of Artemisia dracunculus (AD) leaves aqueous extract on blood sugar, serum insulin, and triglyceride and liver enzymes in Fructose Drinking water (FDW) male rats.
Background:Anabolic-androgenic steroids (AAS) are abused by athletes.Objectives:The present study was designed to evaluate chronic administration of high doses of nandrolone decanoate (ND) on the pituitary-gonadal axis and hematological parameters in normal male rats.Materials and Methods:Thirty Wistar-Albino male rats were divided assigned to control (C), placebo (P) and test (T) groups (n = 10). Group T received 15 mg/kg intramuscular (IM) ND for eight weeks. Group P received the same volume of peanut oil, but group C did not receive any agent during the trial period. At the end, animals were anesthetized, killed and blood samples collected from cervical vessels. Serum follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were determined by sensitive rat gonadotropins kit, using ELISA methods. Serum testosterone and hematological parameters were measured by ordinary laboratory methods. Obtained data was analyzed using SPSS 17 by ANOVA and Tukey statistical tests. Results were expressed as Mean ± SD. Statistical difference considered significantly by P < 0.05.Results:Serum testosterone, LH, FSH, weight gain, food and water intake in group T were significantly decreased compared to other groups (P < 0.05). In addition erythrocyte, leucocytes, hemoglobin and hematocrit in group T were significantly increased compared to those of other groups (P < 0.05).Conclusions:Chronic administration of high doses of ND can alter serum FSH, LH and testosterone and hematological parameters in male rats.
Background: Since gold nanoparticle (AuNP) has shown anti-oxidant activity, this study was designed to assess the effect of AuNP on the liver toxicity induced by Carbon -Tetrachloride (CCl4) in rats.
Background:Aloe vera is a medicinal herb used as an anti-inflammatory and sedative agent.Objectives:The current study aimed to evaluate the effect of Aloe vera aqueous extract on morphine withdrawal symptoms in morphine-dependent female rats.Patients and Methods:The current research was performed on 40 female Wista-Albino rats which were made dependent on morphine using Houshyar protocol and were randomly divided into five groups (A, B, C, D, and E). Group A did not receive any agent in the period of handling but other groups (B, C, D and E) received 5, 10, 20 and 40 mg/kg of Aloe vera aqueous extract by gavage, three times daily for a week, respectively. Withdrawal symptoms, stool form, agitation, disparity, floppy eyelids, and body mass variations were checked for 10 days. The obtained data were analyzed using SPSS v.11 software, and Friedman, Kruskal-Wallis, and Mann-Whitney statistical tests. Statistical difference was considered significant (P < 0.05).Results:The results of the present study showed that agitation, disparity, and floppy eyelids in group E were significantly higher than those of others groups; however, these symptoms in group C were significantly lower than those of the other groups.Conclusions:The results of the present study revealed that the Aloe vera aqueous extract had various effects on morphine withdrawal syndrome in morphine-dependent female rats .
