Purpose: The aim of this study was to review systemically journals on the studies for complementary and alternative medicine in the treatment of endometriosis. Methods: Through medical websites, foreign clinical literatures about complementary and alternative medicines of endometriosis were searched. The cite used was http://www.Pubmed.gov. And then they were divided into three groups. In vitro, in vivo, clinical studies. Results: 1. We researched 2 papers about in vitro. Both were used extract of herbal mixture. And they used CCL5, SE-1, COUP-TF, 17-$\beta$-HSD1, 17-$\beta$-HSD2 which were not commonly used in Korea. 2. We researched 8 papers about in vivo. Most of them used blood-activating stasis-dispelling medicine, just few used tonic medicine. And they used acupuncture which were not used in Korea. Most of Korean paper also used blood-activating stasis-dispelling medicine and rarely used tonic medicine. 3. We researched 19 papers about clinical studies. They had much more cases(average=60) than Korean paper. They were also used western medicine randomized sham-controlled trial. Conclusion: Afterward we need to study for comparing western medicine and herb medicine. And we concern about acupuncture therapy.

Heavy metals are well known as important environmental pollutants and also considered as endocrine disrupters. This study was performed to evaluate the direct effects of heavy metals such as cadmium (Cd), zinc (Zn), mercury (Hg), lead (Pb), cobalt (Co), and arsenic (As) on the various steroidogenic enzymes in frog ovarian follicles. Ovarian follicles from Rana catesbeiana were isolated and cultured for 18 hours in the presence of frog pituitary homogenate (FPH, 0.05 gland/ml) or various steroid precursors with or without heavy metals (0.01-100 ${\mu}M$), and steroid levels in the follicle or culture medium were measured by radioimmunoassay (RIA). Thus, the steroidogenic enzyme activities were indirectly evaluated by measuring the converted steroid levels from the added precursor steroid. Among heavy metals, Hg, Cd and Zn significantly inhibited FPH-induced pregnenolone ($P_5$) production by the follicles ($EC_{50},\;4.0{\mu}M,\;25.6{\mu}M\;and\;5.7{\mu}M$, respectively ), and also suppressed the conversion of testosterone (T) to estradiol $17{beta}\;(E_2)\;(EC_{50},\;4.2{\mu}M,\;7.5{\mu}M\;and\;80.0{\mu}M) while Pb, Co and As are not or less effective in the inhibition. Other enzymes such as $C_{17-20}$ lyase and $17{\beta}$-hydroxysteroid dehydrogenase ($17{\beta}$-HSD) were suppressed only in the high concentration of Hg, Cd and Zn. Taken together, these data demonstrate that cytochrome P450 side chain cleavage (P450scc) and aromatase are much more sensitive to heavy metals than other steroidogenic enzymes and Hg, Cd and Zn show stronger toxicity to follicles than other heavy metals examined.

Background: A number of reports have described the protective effects of ginsenoside Rg1 (Rg1) in Alzheimer's disease (AD). However, the protective mechanisms of Rg1 in AD remain elusive. Methods: To investigate the potential mechanisms of Rg1 in ${\beta}$-amyloid peptide-treated SH-SY5Y cells, a comparative proteomic analysis was performed using stable isotope labeling with amino acids in cell culture combined with nano-LC-MS/MS. Results: We identified a total of 1,149 proteins in three independent experiments. Forty-nine proteins were significantly altered by Rg1 after exposure of the cells to ${\beta}$-amyloid peptides. The protein interaction network analysis showed that these altered proteins were clustered in ribosomal proteins, mitochondria, the actin cytoskeleton, and splicing proteins. Among these proteins, mitochondrial proteins containing HSD17B10, AARS2, TOMM40, VDAC1, COX5A, and NDUFA4 were associated with mitochondrial dysfunction in the pathogenesis of AD. Conclusion: Our results suggest that mitochondrial proteins may be related to the protective mechanisms of Rg1 in AD.

Nandrolone, 19-nortestosterone, is a synthetic androgenic-anabolic steroid promoting muscle growth. Nandrolone is also present in pig meat and sera at non-negligible levels. A number of scientific reports have suggested a positive relationship between incidence of infertility and increased meat consumption in humans. The present study was designed to determine out the effect of feeding nandrolone on the testis of the male reproductive tract. Mixtures of food and nandrolone at different concentrations (0.005 ppm and 0.5 ppm) were supplied to pubertal male rats for 6 weeks. Body weight was recorded every week during the entire experimental period. At the end of the treatment, the testis, epididymis, and epididymal fat were collected and weighted. Sperm numbers in the caudal epididymis were counted. Differential gene or protein expression of steroidogenic enzymes in the testes among experimental groups was determined by semi-quantitative real-time PCR or western blotting analysis, respectively. Histological changes of the testis induced by nandrolone treatment were examined by hematoxylin and eosin staining. Immunohistochemical analysis was employed to detect changes in the localization of steroidogenic enzymes in the testes among experimental animals. There were no significant changes on body, testis, epididymis, and epididymal fat weights among experimental groups. A significant increase of caudal sperm number was found in the 0.5 ppm nandrolone-treated group. Histological examination of the testes noted a high frequency of germ cell sloughing in seminiferous tubules of 0.5 ppm nandrolone-treated rats. Even though transcript levels of $3{\beta}$-hydroxysteroid dehydrogenase (HSD) I, $17{\beta}$-HSD4, and $17{\alpha}$-hydroxylase were influenced by nandrolone treatments, protein levels of all molecules examined in the present study were not significantly affected. Immunohistochemical analysis showed no visible changes in the localization of steroidogenic enzymes in the testes among experimental groups. The current study showed that oral intake of nandrolone in male rats for 6 weeks did not cause significant damage to the testis. It is considered that a feeding effect of nandrolone on male fertility would not be remarkable.

A neurotoxin, 6-hydroxydopamine (6-OHDA) has been widely used to create animal model for Parkinson's disease (PD). The present study was undertaken to examine whether depletion of brain dopamine (DA) stores with 6-OHDA can make alteration in the activities of the testicular steroidogenesis in adult rats. Young adult male rats (3 months old) were received a single dose of 6-OHDA (200 ${\mu}g$ in 10 ${\mu}{\ell}$/animal) by intracerebroventricular (icv) injection, and sacrificed after two weeks. The mRNA levels of steroidogenesis-related enzymes were measured by qRT-PCRs. Serum testosterone levels were measured by radioimmunoassay. Single icv infusion of 6-OHDA significantly decreased the mRNA levels of CYP11A1 (control:6-OHDA group=$1:0.68{\pm}0.14$ AU, p<0.05), CYP17 (control:6-OHDA group=$1:0.72{\pm}0.13$ AU, p<0.05). There were no changes in the mRNA levels of $3{\beta}$-HSD (control:6-OHDA group=$1:0.84{\pm}0.08$ AU) and $17{\beta}$-HSD (control: 6-OHDA group=$1:0.63{\pm}0.20$ AU), though the levels tended to be decreased in the 6-OHDA treated group. Administration of 6-OHDA decreased significantly the mRNA level of StAR when compared to the level of saline-injected control animals (control:6-OHDA group=$1:0.72{\pm}0.08$ AU, p<0.05). Treatment with single dose of 6-OHDA remarkably lowered serum testosterone levels compared to the levels of control group (control:6-OHDA group=$0.72{\pm}0.24:0.13{\pm}0.03ng/m{\ell}$, p<0.05). Taken together with our previous study, the present study demonstrated that the activities of hypothalamus-pituitary-testis hormonal axis could be negatively affected by blockade of brain DA biosynthesis, and suggested the reduced reproductive potential might be resulted in the animals. More precise information on the testicular steroidogenic activities in PD patients and PD-like animals should be required prior to the generalization of the sex steroid hormone therapy to meet the highest standards for safety and efficacy.

Aquaporin (AQP) family protein은 일종의 수분 전달 통로 역할을 하는 단백질로 AQP를 통한 수분의 조절은 삼투압을 통한 물의 이동과 함께 조직내 정상적인 수분의 상성 유지에 필수적이다. 현재까지 11종의 AQP이 신장·뇌·정소·안구 등에서 발현이 확인되었다. AQP9은 물 뿐 아니라 carbamide, polyol, purine, pyrimidine, urea, glycerol 등의 이동에 관여한다. 본 연구에서는 생쥐에서 출생 후 성체에 이르는 동안 정소 내 AQP9의 발현, Leydig cell의 분화에 따른 AQP9의 발현을 조사하였다. 1, 2, 4, 8주령의 정소로부터 semiquantitative RT-PCR 및 real time PCR 법으로 AQP9의 발현을 분석한 결과 1주령에서는 발현되지 않았고 2주령에서는 미량이 발현되기 시작하였고, 4주령에서는 성체의 1/2수준으로 발현량이 급격히 증가하였고 성체에서는 다량으로 발현됨이 확인되었다. Semiquantitative RT-PCR 법과 real time PCR법을 비교할 때 주령별 발현 양상은 유사하였으나 4주령과 성체에서는 두 시험법 사이에 양적인 차이가 있었다. 면역조직화학염색 결과 주로 Leydig cell에서 AQP9의 발현이 확인되었다. 성체의 정소 균질액의 Western blot 상에서 분자량 80, 55, 35 및 23 kDa의 항원이 검출되어 dimer, trimer 형태로 존재할 가능성과 당쇄 결합에 의한 단백질의 변형이 있는 것으로 추정된다. 미성숙 개체의 정소에서는 23 form이 확인되는 반면 성체에서는 35 kDa form이 주로 발현되므로 정소에서 발현되는 AQP9의 경우 Post-translation 수준에서 AQP9의 변형이 수반되는 것으로 사료되며 AQP9의 기능과의 연관성은 추후 연구되어야 할 것이다. Leydig cell은 fetal 및 adult type 2종의 세포가 정소발달 과정에 출현, 사멸, 분화하며 이들은 각기 정소발달, 성숙과 정자형성에 필요한 steroidogenesis에 관여한다. 정소 내 AQP9의 발현은 17beta HSD의 발현 양상과 같게 나타나므로 성적 성숙에 따른 정소 내 AQP9의 발현의 증가는 adult type Leydig cell의 분화와 관련된 것으로 추측된다. 성체의 정소로부터 분리한 Leydig cell-enriched culture에 hCG를 처리한 결과 배양체의 AQP9의 발현이 증가하므로 AQP9은 LH 수용체 하위 신호전달과정을 통해 Leydig cell의 steroidogenesis 또는 생성된 steroids의 분비에 요구되는 수분 및 중성용질의 이동에 관여하는 것으로 사료된다.

This study investigated the effects of a mixture of fenugreek seeds and Lespedeza cuneata extracts on testosterone synthesis in TM3 cells that were oxidatively stressed with $H_2O_2$. In order to oxidatively stress TM3 cells, the cells were treated with $50{\mu}M$ hydrogen peroxide for 4 hr in serum-free media. Yagwanmun-horopa mixture (YHM) showed neither cytotoxicity nor increment of cell proliferation in the oxidatively stressed TM3 cells in any concentration. When the cells were treated with hydrogen peroxide, testosterone levels decreased, but the testosterone level was returned to that of the control level in the presence of YHM. In order to find out the reasons for the increase of testosterone, the expression of the genes involved in the synthesis or disintegration of testosterone. On the other hand, the levels of $3{\beta}$-HSD4 and 17, 20-desmorase, which are involved in testosterone synthesis, were decreased through the use of hydrogen peroxide and were recovered through YHM treatment. Aromatase and $5{\alpha}$-reductase2, which convert testosterone to estradiol and dihydrotestosterone, respectively, were increased through the use of hydrogen peroxide, and were returned to control level through YHM treatment. These results suggest that YHM does not affect TM3 cell proliferation. However, YHM increases the expression of testosterone-synthesizing enzyme, which was decreased through oxidative stress, and decreases the expression of testosterone- converting enzyme, which was increased through oxidative stress. Therefore, it is reasonable that YHM has strong recovery activity on testosterone to normal level, even in the oxidatively stressed TM3 cells which mimics the andropause state.
