Cytokines released from innate immune cells play key roles in the regulation of the immune response. Red Ginseng (RG, steamed and dried root of Panax ginseng C.A. Meyer) is known to show different pharmacological effects by changed composition of saponins compared with Panax Ginseng. In this study, we examined the immunomodulatory effects of RG on the regulation of cytokine release in mice. RG was injected i.p at doses of 0.5, 5 and 50 mg/kg for 6 weeks. We assessed that the weight index of immune organs such as thymus, and spleen, and the mitogen blastogenesis of splenocytes. We also determined the levels of circulating cytokines in serum from RG-treated mice using ELISA assay. The weight index of thymus and spleen, and proliferation of mitogen response of splenocytes have increased in the RG-injected groups. In addition, the levels of IFN-${\gamma}$, TNF-${\alpha}$, IL-6, IL-12 and IL-2 concentrations have significantly increased in the serum of RG-treated mice, but that of IL-10 has not. These results suggest that RG has immune stimulating effects and could be useful as a immunoregulator of circulating cytokine release in vivo.

Atopic dermatitis (AD) is a chronic inflammatory skin disease accompanied by severe itching, mainly before five. The aim of this study is to investigate the effects of 405 nm+850 nm LED light therapy on AD-like symptoms in NC/Nga mice. The mice were randomly placed in the normal (Vehicle), atopic dermatitis-induced (CON), and 405 nm + 850 nm LED light therapy (LED) groups. The LED experimental group conducted 405 nm+850 nm wavelength LED ray therapy for 10 minutes a day for seven days. LED light therapy research confirmed the improvement and improvement of Dermatics score and observed the reduction of epidermal tissue thickness caused by dermatitis. Based on the significant decrease of serum IL-1𝛽 and transdermal moisture loss and serum IgE concentration due to LED light therapy, LED light therapy can help restore normal skin conditions in mice that cause atopic dermatitis. This study showed the anti-atopic effect of infrared light and blue light. Light in mice with atopic dermatitis led to the simultaneous use of circular LEDs with two wavelengths.

Purine has been identified in the preparation of follicular fluid and shown an activity in maintaining oocyte meiotic arrest. Therefore this study was performed to examine the inhibitory effect of purine on germinal vesicle break down(GVBD) in the presence and absence of human fetal cord serum(HFCS) or human mature follicular fluid(HMFF), as a protein source, in vitro culture. Immature oocytes(GV stage) were collected from ovaries of 21∼28 days old ICR mice by puncturing the antral follicles with a fine needle, at 48 hrs after PMSG injection. Some of the oocytes were denuded by drawing the cumulus-enclosed(complex) oocytes in and out of a pasteur pipet. Complex oocytes and denuded oocytes were cultured 3 hrs. in T6 media containing 0.75mM adenosine or/and 4mM hypoxanthine, with HFCS or HMFF. Their GVBD rates were observed at every 1 hr. during the culture time. Both adenosine and hypoxanthine have shown a time-dependent inhibitory effect on GVBD in complex and denuded oocytes and the inhibitory effect was maximized in culture medium containing hypoxanthine and adenosine. HFCS and HMFF increased the GVBD rates in the presence of the purines, thus HFCS and HMFF may contain a factor that could reverse the inhibitory effect of purines. Also complex oocytes were more sensitive to not only the inhibitory effect of purines but the promoting action of HMFF on GVBD than denuded oocytes. Therefore it was reconfirmed that granulosa cells play an important part in meiotic arrest and resumption.

본 연구는 생식주기중 폐쇄여포액내에서 생물학적， 면역학적 특성을 나타내는 GTH 의 변화를 조사하고 steroid hormone과의 상관관계를 조사하며 국부조절인자로서 의 GTH의 역 활을 조사하고자 하였다. 가임기간중 215개의 여포와 IVF과정에서 185개의 여포를 얻어 여포액내 GTH의 생물학적 또는 면역학적 활성을 측정하였다. Bioactive LH(bLH)는 생쥐의 Leydig cell-testosterone production assay, bFSH는 흰쥐의 Sertoli cell aromatase assay로 측정 하였 다. Immunological GTH(iLH , iFSH) 는 MaiaClone RIA , Delfia kits를 사용하였다. 여포액내 iLH, iFSH , ihCG 는 hyperstimulation에 의해 형성된 여포의 크기와는 무관하였다. 또 hMG, huFSH 의 처리와도 상관성이 없었다. T의 농도가 높은 여포액내의 iFSH는 현저히 낮았으며 E, P 가 고농도인 여포의 ihCG 양은 현저히 낮았다. 과배란이 유도된 난소의 여포액내 iLH는 LH specific RIA로 측정시 3mIU/ml 이하이었다. 생식주기중 여포액내 bLH, bFSH는 배란기에 현저히 증가 하였다. 혈청내 GTH B/I ratio는 엘정한 반면 여포액내 LH，FSH의 생물학적， 면역학적 활성은 미수정란을 가지거나 폐쇄된 여포내의 활성보다 현저하게 높았다. 위의 결과로 보아 여포액내 생식소자극호르온은 면역학적활성보다 높은 생물학적 활성을 가지며， 생리적 현상의 지표가 된다고 추론된다. 또한 steroid, bGTH는 여포의 선택， 폐쇄를 구분하는 지표로 사용가능하며， 여포가 폐쇄될때 여포액내 B/I ratio가 현저히 낮아지는 것으로 보아 GTH의 활성이 감소되는 것으로 판단된다.

Hyperlipidemia has been treated as one of the most important etiological cause factor in 21th century. The cortex and root of Acanthopanax sessiliflorus (AR), a herbal medicine, have been used for several diseases including cardiovascular diseases in Oriental countries. Recently, we reported that AR has anti-hyperlipidemic action. BS-01 was made using extract from AR. For these reasons, we investigated the effects of BS-01 as anti-hyperlipidemic drug through measurement of body weights, cholesterol levels, total lipid, phospholipid in serum. In our results, mice induced by high fat diet elevated body weight level compared to naive group. And total lipid in serum was also elevated by induction of hyperlipidemia. In BS-01 group, body weight of mice was lowered significantly compared to that of control group. Oral administration of BS-01 decreased total cholesterol and triglyceride level back to that of naive mice. HDL and LDL cholesterol levels were not affected by BS-01. In addition, total lipid level, which elevated by induction of hyperlipidemia was also lowered by oral administration of BS-01. Finally, free fatty acid level was lowered in BS-01 group. These results demonstrate that BS-01 lowered body weight and titers involved in hyperlipdemia such as total cholesterol, triglyceride, free fatty acid and total lipid. In these results, we demonstrate that BS-01 has anti-hyperlipidemic action.

These expriments were carried out to investigate existence of H-Y antibody in the rat serum immunized against H-Y antigen from rat spleen cells and effect of H-Y antiserum on development of mouse male embryos. The results obtained were summerized as follows : 1. When mouse embryos were cultured for 48∼72 hrs in the Ham's F10 containing 16% of FBS(fetal bovine serum) or RNS(rat normal serum), percentages of embryos developed from 2, 4, 8 and 16-cell embryo to morulae were 20, 27, 94 and 100%, respectively, in FBS and 8, 7, 94 and 100%, respectively, in RNS. Eight to 16-cell embryos showed no difference in development rate between FBS adn RNS. 2. When 8∼16-cell mouse embryos were cultured for 24∼48 hrs in the Ham's F10 containing FBS, RNS＋GPC(guinea pig complement) and RAS(rat antiserum)＋GPC, proportions of embryos developed to the expanded blastocyst stage were 100, 82.4 and 52.1∼53.6%(ave.52.9), respectively, so that it was suggested that rat antiserum suppressed development of male embryos. 3. When 8∼16-cell mouse embryos were cultured for 24∼48 hrs in the Ham's F10 containing FBS, RNS, RNS＋GPC and RAS＋GPC, proportions of embryos developed to the expanded blastocyst stage were 94.5, 90.9, 82.3 and 47%, respectively, and the embryos developed in the medium containing RAS＋GPC seemed to be female. These results indicated that the antisera prepared through immunized against H-Y antigen from rat spleen cell, possessed H-Y antibody which supressed development of male embryos.

Saponins, the major component of ginseng root, mediate the pharmacological action of the ginseng. It has been reported that ginseng roots have protective effect against various toxins. In this study, the effects of ginseng total saponin (GTS) on tumor necrosis factor-alpha (TNF-$\alpha$) production induced by bacterial toxin was investigated. TNF-$\alpha$ level in lipopolysaccharides (LPS)-activated serum was remarkably reduced by intraperitoneal administration (50 mg/kg)of ginseng total saponin (GTS) into mice. The inhibitory effect against TNF-$\alpha$ production was not significant when GTS was given after the LPS injection, and by oral administration. These results suggested that ginseng root may have protective activity against liver damage accompanying the overproduction of TNF-$\alpha$ and GTS is the active component of ginseng.

Glycyrrhiza korshinskyi Grig. (Gk), which is a new variety of Glycyrrhiza, was developed by the National Institute of Horticultural and Herbal Science in Korea Rural Development Administration. It is improved the limitations of traditional Glycrrhiza species such as G. uralensis Fisch., G. glabra L., and G. inflata Batal. and has been reported various pharmacological effects. The aim of this study is to investigate the protective effect of Gk on the acute pancreatitis, because which has not been revealed yet. AP was induced via intraperitoneal injection of cerulein (50 ㎍/kg) hourly for 7 times in C57BL/6 mice. Gk water extract (20 or 50 mg/kg) or saline was administrated via oral gavage 1 h before the first injection of cerulein. The mice were sacrificed at 5 h after the final injection of cerulein. The inflammatory cell infiltration in pancreatic tissue was decreased by the administration of Gk water extract compared to the AP group. Also, serum amylase and lipase levels were decreased by the administration of Gk water extract compared to the AP group. These results suggest that Gk have protective effect on the acute pancreatitis.

There is a rising trend in obesity due to various factors, including changes in eating habits, lack of exercise, and genetic and psychological factors. Citrus peel has been reported to prevent obesity via antioxidative, antihypertensive, and LDL cholesterol-lowering effects. This study investigated the effects of citrus peel extract fermented with or without Aspergillus oryzae in a mouse model of diet-induced obesity. The animals were divided into four groups: a high-fat diet group (HFD), a normal fat diet (NFD) group, a citrus peel extract (CP) group, and a citrus peel extract fermented with A. oryzae (CPA) group. The citrus peel extract improved lipid metabolism and weight loss in the high-fat diet-induced obese mouse model. As expected, the body weight was higher in the HFD group compared with the NFD, CP, and CPA groups. However, the concentrations of total cholesterol (TG) and triglyceride (TC) in the serum and liver of the CP and CPA groups were lower than in the HFD group. There were no significant differences in the HDL cholesterol concentration among the groups. Taken together, our results suggest that extract of citrus peel biotransformed with A. oryzae had more antiobesity activity than citrus peel not transformed by A. oryzae through the fermentation of metabolites.
