Background & objectives: Some herbs contain compounds with antioxidant activity and can be used to protect or cure damages caused by chemical toxins. The aim of this study was to evaluate the effects of carbon tetrachloride (CCl4) on total antioxidants in various tissues and Tanacetum parthenium impacts on reducing devastating effects of carbon tetrachloride.
Methods: A total of 42 male Wistar rats were divided into seven groups of six animals in each group: normal control, damaged control, three groups that treated with 40, 80, and 120 mg/kg of Tanacetum parthenium extract 14 days before CCl4 injection and two groups served as post-treatment groups that received 80 and 120 mg/kg extract 2, 6, 24, and 48 h after CCl4 injection. At the end of study the liver, kidney, testis, and heart were removed and then homogenized and then the antioxidant activity of the tissues assessed using FRAP method. Results were analyzed by one-way ANOVA test.
Results: The results showed that the injection of carbon tetrachloride significantly decreasestotal antioxidant in both liver (p<0.001) and kidney (p<0.05) tissues. Administration of extract significantly (p<0.05) increased the total antioxidant of liver and kidney.
Conclusion: Protective effect of Feverfew against CCl4 induced damages is more effective in liver and kidney than testis and heart..

Background & objectives: Terfezia boudieri (TB) has more than 15 types of proteins, gallic acid, catechins, flavonoids, tannins and other compounds such as beta-carotene and linoleic acid. Some of these compounds have antioxidant and anti-hyperlipidemia effects. Therefore, this study aimed to examine the antioxidant and protective effects of this fungus on the liver injury induced by carbon tetrachloride.
Methods: 30 male Wistar rats were divided randomly into 5 groups (each group containing 6). Group 1 (normal control group) and group 2 (control CCl4) were given normal saline for 14 days. Group 3, 4 and 5 received 500, 1000 and 1500 mg/ kg doses of methanol extract of TB for 14 days, respectively before the injection of carbon tetrachloride. In the fourteenth day, all groups except group 1 were given 1.5 ml/kg of carbon tetrachloride (V / V 1: 1 dissolved in olive oil). Group 1, instead of carbon tetrachloride, received 1.5 ml/kg of olive oil on the fourteenth day.
Results: Injection of carbon tetrachloride in rats increased serum activity of ALT, AST, ALP and serum degrees of triglycerides, VLDL, LDL, HDL, total cholesterol, glucose, and reduced HDL and total antioxidant capacity (TAC); while pre-treatment with methanol extract of TB significantly reversed the changes.
Conclusion: The results of this study showed that methanol extract of TB can protect the liver against oxidants and free radicals produced by carbon tetrachloride metabolism.

Background & objectives: Terfezia Boudieri (TB) has been used as a sexual stimulant for men in traditional medicine. TB containing fatty acid, flavonoids, beta-carotene, minerals and antioxidants such as, catechin, therefore, this study aimed to investigate the effects of the hydroalcoholic extract of Terfezia Boudieri on sperm and testosterone levels in male rats.
Methods: In this study, 21 adult male Wistar rats, each weighing approximately 250±20g, were randomly divided into three groups (n=7). The first group (control) with no treatment, the second group (sham group) received normal saline (extract solvent) and the third group, was injected intraperitoneally (IP) with 105 mg / kg of methanolic extract of Terfezia boudieri (TBME) (0.2 ml) for 21 days. The blood samples were collected to determine the concentration of testosterone and finally, the weight and size of the testicles and epididymis, the number and the percentage of sperm moving were evaluated Data were analyzed using ANOVA and Turkey's post- hoc tests.
Results: The results of the present study showed that serum levels of testosterone, body weight of rat, testis weight , sperm count and sperm motility in the experimental group were significantly increased compared with the control group (p<0.001).
Conclusion: The results of this study showed that TB at 105 mg/kg dosage can increase the levels of testosterone and improve sperm parameters and therefore, TB can be used to treat sexual impotence and infertility in males.
