The Influence of the Myricetin on the Liver, Kidney, Spleen and Some Endocrine Glands of Male Rats at Prepubertal Period

Abstract

In this study, the effects of myricetin exposure to rats from postnatal day (PND) 23 to 53 at various doses were investigated. The male rats were divided into five groups and each group consisted of six animals. Group of rats were treated with myricetin 25 and 50 mg/kg/day in a suspension of corn oil. Positive control males were received gavage orally with 17α-ethinyl estradiol 0.7 and 7 µg /kg /body weight day and control males were received corn oil. End of the study, weights of liver, kidney, spleen, pancreas, thymus and adrenal gland were measured. Organ/body weight ratios were calculated and tissue sections were examined histologically. In liver, the TUNEL method was applied and evaluated. In results, absolute liver weights were decreased statistically in 0.7 and 7 µg/kg/day etinil estradiol and 50 mg/kg/day myricetin treatment groups, compared with the oil control group. Histopathological examination of the liver, kidney and spleen revealed significantly increased frequency of congestion, cell degeneration and mononuclear cell infiltration when compared with the control group. Also myricetin dose groups, the apoptotic cells were increased. This study demonstrated that orally gavages myricetin caused adverse effects on male liver, kidney, spleen and endocrine glands, during peripubertal period to pubertal period.
