The Effects of Vitamin E on Liver and Kidney Damage Induced by Dianabol in Small Laboratory Mice

BACKGROUND AND OBJECTIVE: Anabolic steroids, especially dianabol, are used by athletes as a performance-enhancing drugs that damage the liver and cause structural changes. The aim of this study was to evaluate the effects of vitamin E on liver and kidney toxicity caused by dianabol. METHODS: In this experimental study, 72 adult male mice were randomly divided into 8 groups of 9. Four groups of mice received 100 IU / kg vitamin E orally for 42 days through gavage. Three groups of the above groups received 5, 10 and 20 mg / kg oral dianabol four hours after receiving vitamin E, respectively. The control group and the groups receiving only 5, 10 and 20 mg / kg oral dianabol were also considered. 24 hours after the final treatment, serum samples were collected for biochemical evaluations and tissue samples were collected for histological, histomorphometric and histochemical evaluations. FINDINGS: The results showed that dianabol significantly increased the level of AST (158.52±9.76), ALT (113.70±11.02), and ALP (141.30±5.94), and significantly decreased albumin (1.04±0.47) compared to the control group (72.61±7.54, 41.47±7.03, 112.80±4.30, 3.14±0.25, respectively) (p<0.05). Administration of vitamin E significantly increased the level of AST (110.56±9.86), ALT (80.19±4.02) and ALP (120.52±4.94) and improved albumin (2.1±0.28) (p<0.05). CONCLUSION: The results of the study showed that vitamin E can reduce the oxidative damage caused by dianabol in the liver and kidney of the mouse

Protective Effects of Royal Jelly and Vitamin C against Experimental Hemolytic Anemia on Sex Hormones and Histochemical Testicle Tissue Histochemistry of Adult Mice

Introduction: Phenylhydrazine (PHZ) is a well-known hemolytic compound inducing intoxication in erythrocytes. Therefore, the present study aimed to evaluate the protective effects of royal jelly and vitamin C against phenylhydrazine-induced damages in mouse testicles. Methods: In this study, 64 adult male mice were randomly and equally assigned to eight groups. The first group received normal saline (0.1ml) intraperitoneally. The second group received PHZ (6 mg/100 gr) intraperitoneally in 48-hour intervals. The third group received vitamin C (250 mg/kg/day) intraperitoneally perday a long with PHZ. The fourth group received royal jelly (100 mg/kg/day) through gavage. The fifth group received PHZ along with vitamin C and royal jelly in similar doses to the previous groups. The sixth group received only vitamin C, the seventh group recieved only royal jelly, and finally the eighth group received similar doses of vitamin C and royal jelly. After 35 days, serum and tissue samples were taken and used for histochemical (Mallory-Azan, Alkaline phosphatase, Oil red-O and PAS), and serum analyses (Testosterone, LH, FSH). Results: The study results revealed the histochemical changes in testicular tissue of the phenylhydrazine group, in which vitamin C and royal jelly partly improved the changes. Furthermore, serum analyses demonstrated a significant decrease in testosterone, FSH and LH levels, which this decrease was diminished by royal jelly and vitamin C. Conclusions: Royal jelly and vitamin C seem to have the potential to decrease serum and tissue damages induced by phenylhydrazine via restraining free radicals
