카제인은 우유에서 단백질의 주요 급원으로 알려져 있으며, 이에 따라 카제인 유래 생리활성 펩타이드와 체내 작용에 대한 연구들이 지속적으로 보고되어 왔다. 카제인은 모체단백질 내에서는 불활성을 띄지만 여러 종류의 protease의 작용, 미생물 발효 시 효소적인 가수분해 및 위장에서의 소화를 거치면서 모체단백질에서 방출되어 활성을 띄게 된다. 카제인은 체내에서 흡수된 후 여러 생리활성을 지니게 된다. 먼저 심장혈관계에서 카제인 유래 펩타이드는 ACE 저해활성을 가지므로 고혈압을 예방하는데 도움을 줄 것으로 기대된다. 신경계에서는 opioid 유사물질로서 모르핀과 같은 효과를 나타낸다. 면역계에서는 여러 측면에서 면역기능을 조절한다고 알려져 있으며, 마지막으로 영양계에서는 대표적으로 CPP(caseinophosphopeptide) 및 GMP(glycomacropeptide)가 칼슘, 철과 같은 무기질 흡수에 도움을 준다. 이와 같이 카제인 유래 펩타이드의 다양한 생리활성은 다양한 기능성 유제품에 적용되어왔다. 본고에서는 생리활성 펩타이드의 생성, 흡수 및 흡수기전과 이들의 대표적인 생리활성기능 중 심혈관, 신경, 면역 및 영양에 미치는 영향에 대해 논하였다.

This study investigated the effect of Lactiplantibacillus plantarum JSA22-fermented rice drinks on dextran sodium sulfate (DSS)-induced colitis in mice. Twenty-four mice were randomly assigned; No colitis (Con), colitis with tap water (DSS-only), colitis with unfermented rice (DSS-UFR), and colitis with fermented rice (DSS-FR). After inducing colitis with 2% DSS for 5 days, they were given Tap water, UFR drink, or FR drink for an additional 6 days. The DSS-FR group had significantly lower Disease Activity Index (DAI) scores compared to the DSS-only group, but no significant difference with the DSS-UFR group. Colon length was reduced in the DSS-only group. The DSS-only group had significantly higher IL-6 mRNA levels compared to the Con group, while the DSS-FR groups showed significantly lower IL-6 mRNA levels compared to the DSS-only group. These results suggest that rice drinks fermented with Lactiplantibacillus Plantarum JSA22 ameliorate the severity of DSS-colitis, by potentially reducing proinflammatory cytokines.

고빈도 환기법은 최근에 개발되어 임상에 응용되면서 호흡생리학, 마취학, 집중치료의 학등의 분야에서 호흡부전의 새로운 치료법으로 관심이 집중되고 있는 환기법이다. 현재까지 고빈도 환기법중 고빈도 양압 환기와 제트 환기는 비교적 많은 연구가 되고 있고 임상적으로 사용되고 있으나 고빈도 진동 환기법은 제한적으로 사용되고 있다. 앞으로 고빈도 진동 환기법에 대해서도 더 많은 연구가 되어야 할 것이다. 또한 최근 개발되고 있는 고빈도 흉벽 진동 환기와 체표면 진동 환기에도 관심을 기울이면 호흡부전 환자의 치료에 바람직한 새로운 환기법이 될 수 있을 것으로 기대된다. 현재 고빈도 환기법의 몇몇 적용형태는 기관지-늑막루등의 폐압손상으로 인한 병변의 치료외에도 기관수술, 흉부수술, 뇌수술에서 수술부위의 움직임을 최소화시키면서 충분한 가스교환율 이룩할 수 있어서 효과적으로 이용되고 있다. 그러나 응급심폐소생술, 폐쇄성 폐질환, 성인 또는 영아 호흡곤란증후군등과 같은 질환에서의 적용은 더 규명되어져야겠다. 고빈도 환기법의 여러가지 문제점중 적절한 환기빈도의 결정, 충분한 습도를 공급하는 장치, 고빈도 환기의 정확한 감시장치의 개발등은 앞으로 우선적으로 해결해야 할 문제점이다. 또한 임상에 더욱 효과적으로 응용될 수 있는 새로운 환기법이 되기 위해서는 고빈도 환기법의 호흡생리와 안정성등에 관한 연구도 병행되어야겠다.

Cheongpyesagan-tang (CP) is one of the traditional medicinal prescription to treat Taeumin (太陰人)'s disease. It has been commonly used for the treatment of stroke, arthritis, diabetes and obesity. In this study, we investigated an anti-inflammatory potential of CP water extract. We examined the effects of CP on the lipopolysarccharide (LPS)-induced production of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$). We also examined the levels of protein or mRNA of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and proinflammatory cytokines in RAW 264.7 cells. CP inhibited NO and $PGE_2$ production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, CP decreased the mRNA expression of interleukin-6 (IL-6), interleukin-$1{\beta}$ (IL-$1{\beta}$), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). These results suggest that CP has potential as anti-inflammatory therapeutic medicine.

The root bark of Morus alba L. (MA) used in traditional oriental medicine for the treatment of pulmonary diseases exerts various pharmacological activities including anticancer effects. In the current study, we investigated the effects of MA on the migration and invasion of colorectal carcinoma cells. Results from a transwell assay showed that the methylene chloride extract of MA (MEMA) suppressed the migration and invasion of HCT116 human colorectal carcinoma cells in a concentration-dependent manner. MEMA reduced both mRNA and protein levels of matrix metalloproteinase (MMP)-9, but did not suppress the expression of MMP-2 in HCT116 cells. As a molecular mechanism, MEMA inhibited the phosphorylation of mitogen-activated protein kinases (MAPKs), including ERK, JNK and p38, in a dose-dependent manner. In addition, MEMA dephosphorylated both Src and signal transducer and activator of transcription 3 (STAT3) in HCT116 cells. Taken together, we demonstrate that MEMA suppressed the migration and invasion capacity of HCT116 human colorectal cancer cells by downregulation of MMP-9 and inactivation of both MAPKs and Src/STAT3 signaling pathway.

Postherpetic neuralgia(PHN) is one of the most common intractable chronic pain syndromes. This review was conducted to investigates the trends in recent clinical studies of PHN in China and to find out the efficacy of Chinese medicine treatment for PHN. Based on CNKI databases, nineteen randomized controlled trials(RCTs) were analyzed. The search focused on the authors, publication year, sample size, age, duration of illness, treatment period, lesion sites, methods, outcome measures, and results of the selected articles. Four studies used herbal medicine. The most frequently used herbs were Angelicae Gigantis Radix(當歸) and Corydalis Tube(玄胡索). Eighteen studies used acupuncture treatment. The most frequently used acupoints were ST36, LR3, LI4. Three studies used moxibustion and 5 studies used cupping treatment. In all nineteen studies, the efficacy of Chinese medicine treatments was confirmed. More varied and scientifically designed clinical studies are required to develop treatments for PHN. The results of current study could be used as guidance for further studies of treatment on PHN.
