Histological changes of testis and epididymis after partial and total pinealectomy in albino rat have been studied. After 8 and 16 days from total pinealectomy, testicular parenchyma showed morphological aspects of hypotrophy characterized by the absence of spermatozoa in tubular lumen and by tubules lined by an immature seminiferous epithelium. At the 21st day we have noticed a restoration of normal spermatogenesis. Leydig and Sertoli cells did not state significative modifications. After 8 and 16 days from the operation epididymal canalicula presented a narrowed lumen, lined by a pseudostratified columnar epithelium and occupied by numerous immature spermatogenic cells. After partial epiphysectomy we did not notice any significative modification both in the testicular and epididymal parenchyma. A participation of epiphysis cerebri in temporal regulation of spermatogenesis in albino rat male gonads has been hypothesized.

Berry consumption can prevent bone loss. However, the effects of different berries with distinct anthocyanin composition have not been thoroughly examined. The present study compared the effects of blueberry, blackberry, and black currant on bone health using a mouse model of diet-induced obesity. To investigate the effect of different berry supplements against a high-fat (HF) diet in vivo, 40 HF diet-induced obese (DIO) C57BL mice were assigned into four groups and fed a HF diet (35% w/w) with or without berry supplementation for 12 weeks (n=10). We measured adipose tissue mass (epididymal and retroperitoneal), plasma antioxidant, bone-related biomarkers, femur bone mineral density (BMD), and bone mineral content (proximal and distal). Adipose masses were negatively correlated with proximal BMD, but positively associated with plasma superoxide dismutase (SOD) concentrations (P<.001). Berry supplementation did not change the plasma ferric reducing antioxidant power, SOD, and insulin-like growth factor-1. However, the black currant group exhibited greater plasma alkaline phosphatase compared with the control group (P<.05). BMD in the distal epiphysis was significantly different between the blueberry and blackberry group (P<.05). However, berry supplementation did not affect bone mass compared with control. The present study demonstrates a negative relationship between fat mass and bone mass. In addition, our findings suggest that the anthocyanin composition of berries will affect bone turnover, warranting further research to investigate the underlying mechanisms.
