This study was performed using histochemical and immunohistochemical methods to investigate the effect of Gami-Shinkiwhan(GS) on reproductive function of male aged mice. 8-weeks-old ICR mice were used as control group, without any treatment, and 15-month-old ICR mice were used as aging elicited group(AE) and Gami-Shinkiwhan treatment group(GS). AE group didn't restrict diets and drinking for 6 months without any treatment. GS was administered 0.56g/kg/day for 6 months. Compared with AE group, the cell division of sertoli cells, spermatids, and spermatogonial cells was increased and the apoptosis of sertoli cells was decreased on GS group. Androgen receptor positive reaction and $17{\beta}$-HSD positive reaction were significantly increased in the GS group compared to AE group. In addition, the DJ-1 positive reaction was significantly increased and the HDAC3 positive response was significantly decreased in the GS group compared with AE group. Based on the above results, GS prevented the apoptosis of sertoli cells in the tubules, and increased the production of sertoli cells, spermatozoa and testosterone. Based on this, it is thought that it improves male reproductive dysfunction caused by late-onset hypogonadism.

[Purpose] Although physical activity is required to prevent or ameliorate osteoporosis, medicine prescription should precede it, since it may be limited in severe osteoporosis patients. Furthermore, osteoporosis has a great effect on physical activity disorders that accompany fractures and pain, and therefore, research on treatment or prevention to decrease the number of patients is required. The purpose of this study was to discover candidate substances from natural products with an effective pharmacological action and to prepare basic data to help patients. [Methods] To prepare the osteoporosis model, ovariectomy (OVX) was performed using surgical methods. The prepared prescription [Shinkiwhan (SKH), a Korean medicine] was administered orally at a dose of 210 mg/kg/day for 8 weeks. After completion of the animal experiment, the bone mineral density (BMD) was analyzed using double-energy X-ray absorptiometry. The analysis of the effect of drugs on bones was performed using histological analysis and immunostaining. [Results] SKH increased the BMD in the OVX rats. Furthermore, SKH significantly increased the expression of osteoprotegerin and downregulated receptor activator of nuclear factor kappa B ligand and phosphorylation of c-jun N-terminal kinases in the bones of the OVX model. [Conclusion] Our findings suggest a protective effect of SKH against BMD loss in the OVX model.
