It has been known for a long time that Palmiwon water extract can be prescribed for the treatment of deficiency of Yang in oriental medicine. But the exact mechanism of it has not been Known yet. In the present experiments, it was attempted to explain the effect of Palmiwon water extract on the serum Hormone level in rabbits and the antifatigue in mice. Palmiwon water extract oral intake showed a increase of serum hormone level in rabbits and the effects of the antifatigue in mice. The results obtained were as follows. 1. The administration of this medicine was observed to cause continuously a significant increase of the testosterone content in the serum from the 7th day to the 21th day. 2. The estradiol centent in the serum, as compared with the control experiment, was seen to increase significantly by the administration of this medicine from the 7th day to the 21th day. 3. The LH and FSH content in the serum, as compared with the control experiment, indicated a tendency toward an increase by the administration of this medicine from the 7th day to the 21 th day, but with no significant difference. 4. In the effect to Palniwon on the antifatigue in mice, swimming time was prolonged in both sample A, B groups than control group, and significance revealed in both sample A, B groups. These data suggest that Palmiwon water extract can increase serum hormone level and that it can have therapeutic effectiveness to the antifatigue.

본 연구에서는 1-chloro-2,4-dinitrobenzene (DNCB)로 유도한 아토피 피부염 동물 모델인 NC/Nga mice에 대한 Eurya emarginata 에탄올 추출물(EE-70E)의 면역 조절 효능을 확인하고자 하였다. DNCB를 5주간 도포하여 유도한 아토피 동물 모델인 NC/Nga mice에 EE-70E를 3주간 경구 투여한 후 scratching behavior 및 clinical skin severity score, 혈청 면역지표(IL-4, IL-13, IL-17, histamine, IgG1, IgE)의 농도를 측정하였다. DNCB를 도포하여 3주동안 경구 투여한 결과, EE-70E의 200 및 400mg/kg 용량에서 clinical skin severity의 감소, scratching behavior의 감소 및 혈중 IL-4 및 IL-13, IL-17, histamine, IgE의 농도가 대조군과 비교하여 유의성 있게 농도의존적으로 감소하는 결과가 관찰되었다(p<0.05). EE-70E의 경구투여는 NC/Nga mice 아토피 피부염 동물모델에서 면역조절 작용 및 아토피 피부염의 개선 효과를 가짐을 나타냈다. 따라서 EE-70E은 아토피 피부염에 유용한 천연자원으로서 기대된다.

Background and objective: A new formular CPC22 consists of Cynanchum wilfordii root, Pueraria thomsonii flower, and Citrus unshiu peel and has been developed to improve the postmenopausal symptoms. The research intended to evaluate whether CPC22 would regulate bone loss, hot flashes, and dysregulated lipid metabolism in ovariectomized (OVX) postmenopausal mice. Method: The OVX mice were orally administered with CPC22 daily for 7 weeks. Results: CPC22 regulated OVX-induced bon loss by enhancing serum osteoprotegerin, alkaline phosphatase, and osteocalcin levels and diminishing serum receptor-activator of the NF-κB ligand (RANKL), collagen type 1 cross-linked N-telopeptide, and tartrate-resistant acid phosphatase levels. As a result of CPC22 treatment, notable decreases in tail skin temperature and rectal temperature were observed, along with diminishment in hypothalamic RANKL and monoamine oxidase A levels and enhancement in hypothalamic serotonin (5-HT), norepinephrine, dopamine, 5-HT2A, and estrogen receptor-β levels. CPC22 enhanced levels of serum estrogen and diminished levels of serum follicle-stimulating hormone and luteinizing hormone. CPC22 regulated levels of serum lipid metabolites, including total cholesterol, triglycerides, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Furthermore, CPC22 diminished levels of serum blood urea nitrogen, creatine kinase, alanine transaminase, aspartate aminotransferase, and lactate dehydrogenase and restored vaginal dryness without affecting uterus atrophy index and vagina weights. Conclusion: Therefore, these results indicated that CPC22 improves OVX-induced bone loss, hot flashes, and dysregulated lipid metabolism by compensating for estrogen deficiency without side effects, suggesting that CPC22 may be used for the prevention and treatment of post menopause.

BALB/c 마우스에서 감염부위와 감염기간에 따른 숙주 체액 면역반응의 변화를 알아보고자 하였다. 배양한 큰리슈만편모충의 전편모형(promastigote)을 BALB/c 마우스의 코. 등 발바닥 부위로 나누어 각각 $3{\;}{\times}{\;}10^6$마리씩 피하 감염 후 10-100일 동안에 궤양의 형성과정을 관찰하고 채혈하여 SDS-PAGE와 면역이적법을 시행하여 각 부위별로 나타나는 항체 반응을 관찰하였다. 외관상으로는 감염 15일부터 코에 감염시킨 마우스에서 먼저 궤양이 형성되기 시작하였고. 코에 궤양이 나타난 후 2-3일 뒤에 발에서 궤양이 형성되었으며 등에서는 감염시킨 후 90일이 되어서야 궤양이 관찰되었다. 감염후 20일에 실시한 면역이적법에 의하면 코 감염군에서는 202, 139, 98, 83, 81, 67, 65, 62, 59, 54, 52, 42, 26, 23 kDa의 항원성 분획이 관찰되었고 발 감염군에서의 항원 분획양상도 코 감염군과 같았으나 등감염군에서는 202, 83, 81, 65 kDa의 희미한 항원성 분획이 관찰되었다. 그러나 감염 후 90일이 경과한 등 감염군에서는 202, 83, 81, 74, 67, 65, 62, 59, 54, 52, 20, 17 kDa의 항원 분획이 관찰되었다 이상의 결과로부터 감염부위와 감염기간에 따라 큰리슈만편모충에 대한 혈청반응이 항원 분획에 따라 다르게 나타남을 관찰하였다. 이 차이는 세 감염부위의 온도차에 의한 결과일 가능성도 있으나 다른 부위에 감염될 경우 한 숙주 내에서도 다른 면역반응이 유발되어 나타날 수도 있다고 추측하였다. 특히 궤양 형성 시기와 혈청 내 67-52 kDa 분획에 대한 항체 출현 시기가 일치하는 것으로 보아 궤양 형성에 이 항체가 관여할 가능성이 있음을 시사한다.

Immunogenicity of dendritic cell-derived exosomes stimulated with Toxoplasma gondii lysates (TLA exo), mixed with cholera toxin as an adjuvant, was investigated in mice immunized via 2 mucosal routes (ocular vs intranasal). BALB/c mice were injected 3 times with TLA exo vaccine at 2 week interval, and the levels of IgG in serum and IgA in tear, saliva, feces, and vaginal wash were measured. To observe the expression of T. gondii-specific B1 gene, mice infected with ME49 T. gondii cysts were immunized with TLA exo or PBS exo (not stimulated with TLA), and their brain tissues were examined. The mice vaccinated via intranasal route elicited significantly higher humoral and mucosal immune responses compared with mice treated with PBS alone. Also, mice immunized via ocular route (by eyedrop) induced significantly higher T. gondii-specific IgG in serum and IgA in tear and feces in comparison with PBS controls. B1 gene expression was significantly lower in TLA exo vaccinated mice than in PBS or PBS exo vaccinated mice. These results demonstrated that ocular immunization of mice with TLA exo vaccine has the potential to stimulate systemic or local antibody responses. This study also highlighted an advantage of an eyedrop vaccine as an alternative for T. gondii intranasal vaccines.

생쥐에서 페르몬으로 알려진 소수성의 분자와 결합하는 major urinary proteins(MUPs)는 부분적으로 성장 호르몬(GH)의 조절을 받는다. 본 연구에서는 MT-GRF로 형질전환되어 성장호르몬이 증가된 생쥐에서 MUP의 발현을 조사하였다. 이 MT-GRF로 형질전환된 생쥐의 소변에서 MUP이 대조군보다 심하게 저하되어 나타났고, 암컷보다 수컷에서 더 저하되어 나타났다. 또한 MT-GRF를 근육에 주사한 생쥐에서도 MUP는 저하되어 나타났다. 부가하여, MT-GRF로 형질전환시킨 생쥐의 소변에서 전기영동상에서 albumin과 동일하게 이동하는 고분자의 단백질이 다량으로 관찰되었는데 신장의 사구체 여과가 손상되었음을 암시하고 있다. 이 혈장 단백질의 손실도 암컷보다 수컷에서 심하게 나타났다. 결과적으로 GRF의 과다생성은 성별에 차별화된 영향을 미치면서 GH로 형질전환된 동물모델에서 관찰되는 MUP의 발현과 사구체 기능의 변화를 동일하게 유발하고 있었다.

Clostridium difficile causes mucosal damage and diarrhea by releasing two exotoxins: toxin A and toxin B. C. difficile colitis is associated with alterations in bowel flora and the failure to mount an effective antibody response. The aim of the current study was to investigate whether antitoxin sera prevent toxin-A-induced apoptosis, cytoskeletal disaggregation, cell detachment, and tight junction loss in cultured colonic epithelial cells. Serum samples were isolated from mice that survived a C. difficile infection following antibiotic treatment, and the antitoxin effects of these samples were investigated in toxin-A-exposed HT29 colonic epithelial cells and a toxin-A-induced animal model of gut inflammation. Unchallenged mice did not produce IgG against toxin A, whereas serum (antiserum) from C. difficile-challenged mice showed significant IgG responses against toxin A. Treatment with the antiserum markedly inhibited mucosal damage and inflammation in the toxin-A-treated mouse model. In contrast to control mouse serum, the antiserum also markedly inhibited toxin-A-induced DNA fragmentation, dephosphorylation of paxillin and Epo receptor (EpoR), deacetylation of tubulin, and upregulation of p21(WAF1/CIP1) and p53. Taken together, these results reveal that the generated antitoxin serum has biotherapeutic effects in preventing various C. difficile toxin-A-induced cellular toxicities.

Objective: Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) is one of the representative prescriptions for invigoration of vitality and nourishing of the blood. This study was carried out to investigate the effects of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) on hair regrowth and cytokine changes in a shaving model of C57BL6 mice. Method: Five-week-old mice were acclimated for 1 week at a temperature between $21-23^{\circ}C{\acute{E}}$, 40-60% relative humidity, and 12h of a light/dark cycle before beginning of the experiment. There were two groups including normal saline (control) and a positive control of oral intake of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) extract (sample) in 18 female mice. The test compounds were topically treated once a day over 14 days. The hair regrowth was photographically and histologically determined during the experimental period of 14 days. Revelation of TGF-${\beta}1$ and EGF were also determined using immunohistochemistry. In addition to that, IFN-$\gamma$, IL-4 and IL-10 were determined in serum. Results: Hair regrowth in the sample group was promoted earlier and faster than the control group, as shown by concentrations of hairs and thick-hair ratio in the sample group. TGF-${\beta}1$ was not revealed in either control or sample group. EGF was strongly positive in out root sheath of some thick hair of the sample group. Serum IFN-$\gamma$ was significantly decreased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-4 was significantly increased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-10 was decreased in the sample group compared with the control group, but with no real statistical significance. Conclusion: These results suggest that Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) has hair growth promoting activity and it can be used for treatment of alopecia. Also, these effects relate to EGF revelation of hair roots, a decrease in serum IFN-$\gamma$, and an increase of serum IL-4.
