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

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.
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).
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.
Royal jelly and vitamin C seem to have the potential to decrease serum and tissue damages induced by phenylhydrazine via restraining free radicals.
