Objectives: To observe the effects of Herb medication on Polycystic Ovary (PCO) in rats. Methods: Riss (Research Information Sharing Service) was searched for Oriental medicine about PCO on 2000~2014. So, Experimental studies using PCO model induced by Estradiol Valerate (EV) was selected to analyze how effects they were. Consequently, 10 studies published on 2000~2014 were selected to analyze about weight of model and both ovaries, the number aries, the number of follicle and corpus of follicle and corpus luteum, the level of serum Androstenedione (ADD) and total estrogen, the level of Nerve Growth Factor (NGF) and Corticotropin Releasing Factor (CRF), the crossover rate and the number of implantation. Results: Among them, there was significantly difference between treatment group and control group in weight of both ovaries, the number of follicle and corpora lutea, the crossover rate and the number of implantation. Conclusions: The effects of Herb medication was observed on making weight of ovaries with PCO to promote. The study about effect of Herb medication on NGF and CRF with PCOS had to be conducted. The further research have to focus on treatment of subfertility and infertility, that is field showing the advantage of Oriental medicine.

Purpose: This study was designed to investigate the effects of Gaeullijin-Tang(GIT) on the progression of the estradiol valerate(EV)-induced polycystic ovaries(PCO) in rats. Methods: PCO was induced by single intramuscular injection with estradiol valerate(EV)(4mg) in female rats. Normal group(n=8) were injected with sesame oil and orally administrated distilled water for sixty days. PCO control group (n=8) were injected with EV and orally administrated distilled water for sixty days. GIT treated group(n=8) were injected with EV and orally administrated GIT for same duration. At the end day of experiment, we measured weights of body, ovaries, adrenal glands, uterus and contents of serum androsternedione (ADD) and total estrogen. The histomorphometrical changes of ovaries were also evaluated. And we observed the NGF and CRF expression by immunohistochemistry. Results: The results were as follows - The weights(mg) of ovaries in GIT treated group($75.5{\pm}4.3$) were significantly increased(p<0.001) compared with PCO control group($54.3{\pm}4.5$). - The numbers of mature follicles in GIT treated group($5.3{\pm}1.2$) were significantly increased(p<0.05) compared with PCO control group($3.5{\pm}1.2$). - The numbers of corpora lutea in GIT treated group($1.8{\pm}1.3$) were significantly increased(p<0.05) compared with PCO control group($0.3{\pm}0.7$). Conclusion: From the above results, we concluded that Gaeullijin-Tang(GIT) contributes to stimulating normally ovulation by decreasesing ovarian NGF concentrations.

Objectives: This study was designed to investigate the effect of Ojeok-san(OJS) on the estradiol valerate(EV)-induced polycystic ovaries(PCO) in rats. Methods: PCO was induced by single intramuscular injection with estradiol valerate(EV)(4mg) in female rats. Normal group(n=8) were injected with sesame oil and orally administrated distilled water for sixty days. PCO control group (n=8) were injected with EV and orally administrated distilled water for sixty days. OJS treated group(n=8) were injected with EV and orally administrated OJS for sixty days. Then, we measured weights of body, ovaries, adrenal glands and uterus of rats. The histomorphometrical changes of ovaries were also evaluated. And we observed the NGF and CRF expression by immunohistochemistry. Results: The results were as follows - The weights(mg) of ovaries in OJS treated group($57.4{\pm}9.4$) were significantly increased(p < 0.05) compared with PCO control group($42.3{\pm}8.5$). - The numbers of mature follicles in OJS treated group($9.3{\pm}2.5$) were significantly increased(p < 0.05) compared with PCO control group($6.1{\pm}2.1$). - The expressions of NGF-immunoreactive cells in the ovarian granulosa cells in OJS treated group were weaker than PCO control group. Conclusion: From the these results, we concluded that Ojeok-san(OJS) has inhibitory effect on the development of EV-induced polycystic ovary. And it's effect maybe related with decreased NGF activities in the ovary.

Stroke occurs when local thrombosis, embolic particle or the rupture of blood vessele interrupts the blood floe to the brain. $\beta$-estradiol 17-valerate has been reported to exert neuroprotective effects when administered before an ischemic insult. Recently, the pathophysiology of cerebral ischemia has been studied extensively in rat with various methods. In the present study, we investigates whether $\beta$-estrodiol 17-valerate can protect against brain injury. RNA sample were extracted from the hippocampus of female rat, reverse-transcription in the presence of [$\alpha$32p] dATP. Differential gene express-ion profiles were revealed (Bone morphogenetic protein type 1A receptor, Protein disulphide isomerase, Leukemia inhibitor factor receptor, cytochrome bc- 1 complex-x core P, thiol-specific antioxidant protein). RT-PCR was used to validate the relative expression pattern obtained by the cDNA array. The precise relationship between the early expression of recovery genes and stroke is a matter of luther investigation. This Study was supported by the Korea Science and Engineering Foundation(KOSEF) through the Biohealth Products Research Center(BPRC), Inje University, Korea.

Purpose: In this rearch, we made a plan to investigate the effects of Changbuyeukgun-Tang(CET) on the polycystic ovary(PCOS) induced by estradiol valerate(EV) in rats. PCO was induced by single intramuscular injection with EV(4㎎) in female rats. Rats(n=8) in normal group were injected with sesame oil and orally administrated distilled water for 8weeks Rats in PCO control group(n=8) were injected with EV and orally administrated distilled water for 8weeks. Rats in CET treated group(n=8) were injected with EV and orally administrated CET for 8weeks. Methods: We measured the weights of the body, the ovary, the uterus and the adrenal gland. And also, we analyzed ovarian histopathology, NGF and CRF immunohistochemistry. Results: The results were as follows1. the weights(㎎) of the ovaries in CET treated group were significantly increased(p<0.001) compared with PCO control group. 2. the number of the mature follicles in CET treated group were significantly increased(p<0.01) compared with PCO control. 3. the number of the atresia follicles in CET treated group were significantly decreased(p<0.01) compared with PCO control. 4. the number of the corpora in CET treated group were significantly increased(p<0.05) compared with PCO control. 5. the expressions of NGF-immunoreactive cells in the ovarian granulosa cells of rats in CET treated group were less observed than PCO control group. Conclusion: According to these results, we finally concluded that Changbuyeukgun-Tang(CET) has the inhibitory effect on the development of EV-induced polycystic ovary. And we deduced that the effect of it may be related to the decreased NGF activities in the ovary.

Purpose : Polycystic ovarian syndrome(PCOS) is a endocrine disorder and still remains as one of the common causes of anovulation in women of reproductive age. There are some evidences that nerve growth factor(NGF) is involved in the pathogenesis of PCOS. In this research, the effects of ShingihwanhapChangbudodam- Tang(SCT) on the estradiol valerate(EV)-induced polycystic ovary(PCO) were investigated in rats. Methods : PCO was induced by single intramuscular injection with EV(4mg) in female rats. Rats in PCO control group(n = 8) were EV injected and orally administrated distilled water for sixty days. Rats in SCT-treated group(n = 8) were EV injected and orally administrated SCT for same duration. The weights of body, ovary and adrenal gland were measured. And also, ovarian histopathology and NGF immunohistochemistry were performed. Results : The weights of ovaries in SCT-treated group were significantly increased compared with control group. The numbers of secondly and mature follicles, and corpora lutea in SCT-treated group were significantly increased compared with control group. The numbers of atretic follicles were significantly decreased compared with control group. The expression of NGF positive reaction in the ovarian granulosa cells of SCT-treated group were lesser observed than control group. Conclusion : From the these results, we concluded that ShingihwanhapChangbudodam-Tang(SCT) has inhibitory effect on the development of EV-induced polycystic ovary. And it's effect may be related with decreased NGF activities in the ovary.

Objective : This study was designed to investigate the effects of Angelicae Gigantis Radix (AGR) on Polycystic Ovary (PCO) induced by Estradiol valerate (EV) in female rats. Methods : We investigated the effects of AGR on Changes in body weights and food and water uptake for 5 weeks. In addition, we examined the effects on ovary weights. Finally, we also observed histopathological changes in PCO rats. Results : Treatment with AGR did not affect body weights, amount of food and water uptake. Administration group of AGR restored body/ovary weight ratio to normal levels, which were lowered by induction of PCO. In histopathological observation, formation of cysts was suppressed in AGR group compared with non-treated control group. Conclusion : These results suggest that AGR can be used for patients with PCO to prevent formation of cystic follicles and malfunction of ovary.

This study was designed to investigate the effects of Cinnamomi Cortex extract (CC) on hypercholesterolemia induced by Estradiol valerate (EV) in female rats. We investigated the effects of CC on Changes in body weights for 5 weeks. In addition, we examined the effects on fasting blood glucose (FBS) and tested oral glucose tolerance test after oral administration of CC for 5 weeks. We also investigated the effects on levels of total cholesterol, HDL-cholesterol and LDL-cholesterol in serum. Treatment with CC restored weight gain rates suppressed by EV significantly. CC did not affect serum glucose level and glucose tolerance. Levels of total cholesterol and triglyceride were lowered by administration of CC compared to EV treated control respectively. These result suggest that CC can lower serum cholesterol level then prevent weight loss induced by EV. We also suggest the possibility as anti-hyperlipidemic agent of CC.
