Abstract

 Background & Objectives: Spironolactone is a diuretic and antiandrogenic drug and is used in the treatment of hypertention 'secondary hyprealdosteronism congestive heart failure' cirrhosis of the liver, nephrotic syndrome 'androgenic alopecia' gynecomastia and hirsutism. In this research, the effects of spironolactone on the serum LH, FSH, testosterone, dihydrotestosterone, and changes in body weight and testicular tissue in adult male rats, were studied.

 Methods: For this purpose 190 10 g male wistar rats (n=40) were randomly divided into the following grups: control, sham operated (received water) and 25, 50, 100 mg/kg oral spironolactone treated groups. After 14 days body weight and testis weight under laboratory methods, were measured and blood samples were taken from heart and used for the measuring of LH/FSH/testosterone and dihydrotestosterone and then the rates' testes, in order to evaluate the histological changes, were removed and weighed and after obtaining tissue section and staining through HE, they were studied.

 Results: Serum LH level showed a significant increase and testosterone and dihydrotestosterone levels showed asignigicant decrease in 100mg/kg spironolactone treated group ( p 0.05 ) and there was no significant difference among serum FSH level, body weight and testicular weight as compared to control group.

 Conclusion: It can be concluded that oral administration of spironolactone maximum dose for 14 days could increase serum LHlevel and decrease testosterone and dihydrotestosterone levels.

Abstract

Background & objectives: Diabetes mellitus mediated by oxidative stress, creates serious metabolic disorders in testis. Kudzu root with an isoflavonin and saponin contents is often used as antidiabetic and antioxidant. This study aimed at preventing the oxidative effects of diabetes using Kudzu root.

Methods: In this study, 32 male Wistar rats were randomly selected and divided into four groups: control, diabetic and diabetic rats treated with Kudzu 50 and100 mg/kg. Diabetes was induced by intraperitoneal injection of 55mg/kg streptozocin. One week after injection, the rats started to receive Kudzu at the doses of 50 and 100 mg/kg for five weeks by gavage. Testicular damage was examined by using hematoxylin-eosin staining protocol. Hormonal and blood biochemical factors were measured.

Results: The results of this study showed that diabetes causes a high blood sugar levels and reduces the spermatogonia and Sertoli cells with decreased spermatogenesis,sperm count and function. These effects were improved in the treatment groups. Decrease in blood sugar and increase in the number and motility of sperm cells and spermatogonic cells were also observed together with enhanced seminiferous tubule diameter and lower basement membrane thickness.

Conclusion: Kudzu with the ability to reduce blood sugar, improves diabetic-induced testicular damage and can have a therapeutic role in diabetes.v

Abstract


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..

Abstract

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.

Abstract

Background & objectives: The present study examined the gonadotoxic effects of ciprofloxacin antibiotics and protective effects of L-carnitine.
Methods: In this study, 20 NMRI mice were divided into four groups: control, ciprofloxacin, L-carnitine, L-carnitine-ciprofloxacin (each group included 5 animals). The control group received normal saline, the treatment group 1 received 12.5 mg/kg ciprofloxacin, the treatment group 2 received 100 mg/kg L- carnitine and the treatment group 3 received 100 mg/kg L- carnitine and 12.5 mg / kg ciprofloxacin simultaneously. All animals were treated by intraperitoneal administration for 15 days. Testis and epididymis were collected to evaluate sperm parameters (sperm count, motility, morphology and viability).
Results: In the ciprofloxacin group, a significant decrease in sperm count, sperm viability, sperm motility, progressive sperm motility and normal sperm as well as a significant increase in rotating sperm motility, sperm without movement, head and tail abnormalities were observed (p≤0.05). A significant increase in sperm count, sperm survival, motility and progressive sperm motility, normal sperm and a significant decrease in rotating sperm motility, sperm without movement and head abnormalities in the L-carnitine-ciprofloxacin group were observed (p≤0.05); however, the reduction in tail abnormalities of sperm was not significant.
Conclusion: L-carnitine improves sperm parameters in the adult mice treated with ciprofloxacin.

Abstract

Background & objectives: The aim of the present study was to investigate the effects of   oral creatine supplementation on biochemical markers of liver, kidney and testis in the male rats under swimming training plan.
Methods: In this study, male Wistar rats, weighing 245±5gr, were divided into five groups (n=8): control, exercise plus zero dose, exercise plus low-dose, exercise plus moderate dose and exercise plus high dose of creatine (200,300 and 600 mg/kg/d respectively). Biochemical studies of blood serum were performed ten days after creatine supplementation and swimming exercises. Following serum collection, the alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), creatinine and testosterone levels were measured using spectrophotometry method. Statistical analysis was performed by SPSS software using mixed model ANOVA.
Results: serum levels of ALP showed statistically significant differences between groups receiving low and moderate doses of creatine compared to both control and exercise with zero dose  (p<0.05). Also, the results of serum levels of BUN, ALT and AST showed there was no significant difference between the exercise plus zero dose of creatine, exercise plus low-doses of creatine group, exercise plus moderate dose of creatine, exercise plus high dose of creatine groups and control group. The exercise group with high doses of creatine significantly showed a higher serum creatinine level than control group (p<0.05).The serum testosterone level was significantly higher in the exercise with moderate doses of creatine group than in the control group and exercise plus zerecaratin dose (p<0.05).
Conclusion: The results suggested that short-term creatine supplementation (up to 10 days) might adversely affect some biochemical markers of liver, kidney and testis. However, further studies are necessarily needed to clarify the consumption of short-term creatine supplementation.
