라제현,심봉암,정승기,김진주,Ra, Je-Hyeon,Shen, Feng-Yan,Jung, Sung-Ki,Kim, Jin-Ju The Society of Internal Korean Medicine 2009 大韓韓方內科學會誌 Vol.30 No.4
목적 : 이 연구는 백련초의 천식마우스 모델에 대한 효과를 조사하기 위해 수행하였다. 방법: 폐 세척액의 전체 세포와 호산구 수 그리고 폐조직으로의 면역세포의 침윤은 헤마톡실린과 에오신 염색으로 관찰 하였다. Interleukin (IL)-4의 발현량은 Enzyme-linked immunosorbent assay을 이용하여 측정하였으며, NO는 Griess roagont을 이용하였다. 결과 : 천식 병리현상의 하나인 Ovalbumin(OVA)에 의한 전체 세포와 호산구 수의 증가는 백련초 추출물 (200 mg/kg)을 처리한 군에서 감소하였다 (respectively, p<0.001 and p<0.01). 또한 OVA에 의한 증가된 면역세포의 침투는 백련초 추출물에 의해 감소하였다 (p < 0.01). 호산구의 침윤증상은 interleukin (IL)-4 그리고 5를 포함한 T helper (Th) 2 반응과 관련있기 때문에 폐세척액에서 IL-4의 발현량을 조사하였다. OVA에 증가한 IL-4는 백련초 추출물에 의해 감소하였다 (p < 0.05). 천식이 염증성 질병이기 때문에, lipopolysaccharide (LPS)로 자극한 RAW 264.7 세포에서 nitrite (NO) 생성을 살펴보았다. LPS에 의해 증가한 NO 생성을 백련초 추출물 (50, 100 and 200 mg/ml)에서 감소하였다 (respectively, p < 0.05, p<0.01 and p<0.05). 결론 : 이런 결과들은 백련초가 천식의 호산구 침윤에 저해효과를 가지고 있다고 나타내며, 백련초 추출물의 천식을 포함한 염증성 질환의 치료에 치료후보물질로 제안할 수 있다. Objective : This study was undertaken to investigate effects of Opuntia ficus-indica (OP)extract on an asthma murine model. Methods : The total number of cells and eosinophils in BALF and the infiltration of inflammatory cells into lung tissues were determined by hematoxylin and eosin staining. Results : The number of OVA-induced total cells and eosinophils, a phenomenon of asthma, were decreased by treatment of the animals with OP extract (200 mg/kg) (respectively, p < 0.001 and p<0.01). Furthermore, we showed that OP extract reduced the increased immune cell infiltration induced by ovalbumin (p < 0.01). The levels of interleukin (IL)-4 in BAL fluid were measured by enzyme-linked immunosorbent assay, because the eosinophilia is associated with a T helper (Th) 2 response including IL-4. The level of OVA-induced IL-4 was decreased by OP extract in BAL fluid (p < 0.05). We investigated whether OP extract reduced nitrite (NO) production on lipopolysaccharide (LPS)-stimulated RAW 264.7 sells, because asthma is an inflammatory disease. The level of LPS-induced NO production was decreased by OP extract (50, 100 and 200 mg/ml) on RAW 264.7 cells (respectively, p < 0.05, p<0.01 and p<0.05). Conclusions : Our results indicate that OP extract has an inhibitory effect on lung eosinophilia of asthma and suggest that OP extract is a therapeutic candidate in the treatment of inflammatory disease, including asthma.

The Screening of Fermented Medicinal Herbs to Identify Those with Anti-inflammatory Properties
심봉암,라제현,김진주,정승기 대한한방내과학회 2009 大韓韓方內科學會誌 Vol.30 No.1
Objectives : Consumption of fermented foods has been known to alleviate some of the symptoms of atopy, may limit allergy development, and there are also many medicinal herbs proved to be effective for immunologically mediated diseases. In this study, we introduced modern zymology to ferment some herbs to see if fermentation has the possibility of increasing the anti-inflammatory effects of medicinal herbs. Interleukin-4 (IL-4) and interferon-gamma (INF-γ) have been demonstrated to be the main factors in the pathology of allergic diseases. Methods : We measured the levels of IL-4 and INF-γ on concanavalin A-induced BALB/c mice spleen cells, which were treated by fermented and unfermented herbs subsequently. We then compared the fermented groups with unfermented groups to see if the anti-inflammatory effects of the herbs were influenced by fermentation. Results and Conclusions : Our results showed that fermentation had the potential to increase the anti-inflammatory effects of some medicinal herbs, and Astragalus membranaceus and Salvia miltiorrhiza would be the most suitable medicinal herbs for fermentation among the herbs in this study.

과산화수소로 유발된 사람 신경아세포종의 아폽토시스에서 호도 약침액의 신경보호효과

목적: 과산화수소는 산화적 스트레스를 통해 아폽토시스를 유도하는 것으로 알려져 있다. 본 논문에서는 과산화수소로 유발된 신경아세포종 아폽토시스 과정에서 호도약침액의 효과를 관찰하였다. 방법: 과산화수소로 인한 신경아세포종의 아폽토시스에서 호도약침액 의 효과를 알아보기 위해 배양중인 신경아세포종에 과산화수소를 처리하고, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) 분석법, 4,6-diamidino-2-phenylindole (DAPI) 염색법, reverse transcription-polymerase chain reaction (RT-PCR), western blotting의 방법으로 확인하였다. 결과: 과산화수소로 인한 신경아세포종의 아폽토시스에서 호도약침액을 처리한 결과, 약침액을 처리한 세포의 생존이 약 30% 정도 증가하고, 핵 응축과 단편화를 막아주며, CASP3와 BAX단백질의 발현이 감소되었다. 결론: 이러한 결과로 호도약침액이 과산화수소로 인한 신경아세포종의 아폽토시스과정에서 보호효과를 나타내는 것으로 사료된다.
