Objectives: The aim of this study is to investigate immune enhancing effect of Houttuyniae Herba water extract(HW) on RAW 264.7 cell of mouse macrophages. Methods: Effects of HW on productions of nitric oxide(NO) and hydrogen peroxide($H_2O_2$) in RAW 264.7 mouse macrophages were measured. Effect of HW on production of cytokines such as interleukin(IL)-$1{\beta}$, IL-6, and tumor necrosis factor(TNF)-${\alpha}$ in RAW 264.7 cells was accessed by a multiplex bead array assay based on xMAP technology. All of results were represented P<0.05 compared to the normal. Results: 1. After 24 hr incubation, HW increased significantly NO production in RAW 264.7 cells at the concentrations of 25, 50, 100 and 200 ${\mu}g$/mL. 2. After 24 hr incubation, HW increased significantly hydrogen peroxide production in RAW 264.7 cells at the concentrations of 25, 50, 100 and 200 ${\mu}g$/mL. 3. After 24 hr incubation, HW increased significantly IL-$1{\beta}$ production in RAW 264.7 cells at the concentrations of 100 and 200 ${\mu}g$/mL. 4. After 24 hr incubation, HW increased significantly IL-6 production in RAW 264.7 cells at the concentrations of 100 and 200 ${\mu}g$/mL. 5. After 24 hr incubation, HW increased significantly TNF-${\alpha}$ production in RAW 264.7 cells at the concentrations of 50, 100, and 200 ${\mu}g$/mL. Conclusions: These results suggest that HW has immune enhancing activity related with its increasement of NO, hydrogen peroxide, IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ in macrophages.

우리는 방사선피부염 동물 모델을 확립하여, 이차 면역 기관에서의 면역 세포 비율 변화를 관찰하였다. 또한, 방사선 조사에 의한 병소에서 transforming growth factor-${\beta}1$ (TGF-${\beta}1$)과 interlukin-10 (IL-10)의 발현을 증가시킨 세포를 분석하였다. Hairless-1 (HR-1) 쥐의 posterior dorsal 부위에 6 일간 매일 10 Gy 씩 electron (E)-ray를 국부 조사하여 방사선피부염 모델을 만들었다. FACS를 이용하여 면역 세포 비율의 변화를 분석한 결과 비장과 림프절에 존재하는 항원제시세포와 T 세포 및 B 세포들의 비율이 E-irradiation에 의해 영향을 받았다. 피부에서 세포 특이적인 마커와 사이토카인들의 발현 양상은 면역형광염색법으로 확인하였다. 방사선 조사 후, TGF-${\beta}1$과 interlukin-17 (IL-17)은 regulatory T 세포(Treg)보다 keratin-14 (K-14)를 발현하는 진피의 끝부분에서 높게 발현되었다. Interlukin-10 (IL-10)는 Treg 뿐만 아니라 T helper 17 (Th17) 세포, dendritic 세포, macrophage 중 어느 것과도 같은 위치에서 검출되지 않았다. 우리의 데이터는 방사선피부염 동물 모델의 병소 안에서, TGF-${\beta}1$이 증식된 keratinocyte에 과발현된다는 것을 나타낸다.

Objective : The purpose of this study is to investigate the antioxidant activities of Alismatis Rhizoma herbal acupuncture by experimental methods. Methods : For this purpose, first, we put an emphasis in the control of enzymes of the antioxidant system in various changes inside the cell; these changes caused by the proliferation or the activation of the cell which were brought about by the handling of PMA and $TNF-{\alpha}$ into the THP-1 monocyte cell of the body each other. After that, we caused the acute oxidant symptom by the injection of AAPH into the mouse' abdominal cavity, and then applied the herbal acupuncture on S36 point(足三里), and finally, we measured the change of blood ingredient and the resistance against the activated oxygen of the red blood cell membrane, MDA, SOD, and catalase. Results : In vitro the revelation of $IL-1{\beta}$, IL-8, $TNF-{\alpha}$, NOS II and IL-6 were decreased and the revelation of IL-10, $TGF-{\beta}$, GM-CSFIL-12, GM-CSF and SOD were increased. The DNA-binding of $NF-{\kappa}B$ and AP-1 were activated and the formation of ROS in the THP-1 cell line was decreased. In vivo $IL-1{\beta}$ among producing the cytokine inside the plasma was meaningfully dwindled and the $INF-{\gamma}$ was meaningfully increased. The resistance of red blood cell membrane against the activated oxygen was meaningfully increased and the MDA formation was meaningfully dwindled, In the activation of hepatic antioxidase, the SOD was meaningfully increased. Conclusion : Alismatis Rhizoma herbal acupuncture by experimental methods has effected on the antioxidant activities.

${\beta}-Glucan$, one of the major cell wall components of Saccharomyces cerevisiae, is known to enhance the immune function, especially by activating macrophages. Accordingly, in an effort to develop a safe and efficient immune stimulatory agent, we prepared crude ${\beta}-glucan$ (glucan-p1) and partially purified ${\beta}-glucan$ that was free of mannoproteins (glucan-p2), and evaluated their effect on both the macrophage function and resistance to E. coli-induced peritonitis. To investigate the function of the macrophages, phagocytosis, $TNF-{\alpha}$ secretion, oxygen burst, and the expression of cytokine genes such as $IFN-{\gamma}$ and IL-12 were analyzed. Glucan-p2 markedly stimulated the macrophages with all these parameters. Glucan-p1, however, did not stimulate phagocytosis, yet it induced $TNF-{\alpha}$ secretion, oxygen burst, and the expression of $IFN-{\gamma}$ and IL-12, although less efficiently than glucan-p2. Finally, to test the in vivo protective effect of {\beta}-glucan against infection, the survival of mice from E. coli-induced peritonitis was investigated. After 24 h of the peritoneal challenge of E. coli, all of the mice treated with glucan-p2 survived whereas none survived in the control group. Glucan-p1 showed only a marginal effect in protecting the mice. These results suggest that mannoprotein-free gluean-p2, but not gluean-p1, can serve as an effective immune-stimulating agent.

Objective: There is increasing evidence that chronic non-bacterial prostatitis is recognized to be a local inflammatory disease, and there is substantiating evidence to support the role of the inflammatory responses in its pathogenesis, and clinical value in the evaluation of therapeutic efficacy. Prunella vulgaris has been traditionally used in treatment of inflammatory diseases, including of scrofula, goiter, and allergy diseases. In this study, we investigated the effects of Prunella vulgaris on inflammatory cytokines and cytopathological alternation in the rat model of non-bacterial prostatitis induced by castration and $17{\beta}-estradiol$ treatment. Methods: Two-month-old rats were treated with $17{\beta}-estradiol$ after castration for induction of experimental non-bacterial prostatitis, which is similar to human chronic prostatitis in histopathological profiles. Prunella vulgaris as an experimental specimen, and testosterone as a positive control, were administered orally. The prostates were evaluated by histopathological parameters including the epithelial score and epithelial-stromal ratio for glandular damage, and the expression of inflammatory cytokine genes including the interleukin $(IL)-1{\beta}$, IL-5, IL-12, and tumor necrosis factor $(TNF)-{\alpha}$. Results: While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with Prunella vulgaris showed a diminished range of tissue damage. Epithelial score was improved in Prunella vulgaris over that of the control (P<0.05). The epithelial-stromal ratio was lower with Prunella vulgaris when compared to that of the control (P<0.05). In the reverse transcription-polymerase chain reaction (RT-PCR) of inflammatory cytokine genes, Prunella vulgaris inhibited the expression of $IL-1{\beta}$ and $TNF-{\alpha}$ genes, while it modulated the expression of IL-5, which is an anti-inflammatory cytokine. Conclusions: These findings suggest that Prunella vulgaris may protect the glandular epithelial cells and also inhibit stromal proliferation in association with the immune modulation including the suppression of inflammatory cytokines and promotion of anti-inflammatory cytokine. From theses results, we suggest that Prunella vulgaris could be a useful remedy agent for treating chronic non-bacterial prostatitis.

자외선은 피부의 구조적, 생리학적 변화를 일으키는 대표적인 외부 환경 인자로서 광노화, 일광화상 및 피부암을 일으키는 원인이 된다. 이러한 자외선은 외부적인 스트레스 자극 인자로 작용하여 피부 세포 내에서 비활성 코르티손을 활성 코르티솔로 전환시키는 효소인 $11{\beta}$-hydroxysteroid dehydrogenase type 1 ($11{\beta}-HSD1$)의 발현 및 활성을 증가시킨다. 이에 본 연구에서는 UVB에 의해 증가된 $11{\beta}-HSD1$의 발현을 효과적으로 억제할 수 있는 천연 추출물을 발굴하고자 하였다. 사람 섬유아세포에 다양한 천연물을 스크리닝한 결과, 능실 추출물이 유의한 효과가 있음을 확인하고, 능실 추출물을 추가 분획하여 사람 섬유아세포와 3D skin model에서 피부 광노화 억제 소재로서의 가능성을 확인하였다. 능실 추출물 및 분획물은 섬유아세포에서 $11{\beta}-HSD1$의 발현을 억제함과 동시에 자외선에 의한 matrix metalloproteinase (MMP)-1, 3, 9 및 염증성 싸이토카인(IL-6, 8)의 발현 증가를 억제하였다. 또한, 3D skin model을 이용한 평가에서, 능실 추출물은 UVB에 의한 MMP-1 단백질 발현을 억제하였고, UVB에 의한 표피 두께 감소 및 각질형성세포의 증식 감소를 회복시켰다. 따라서, 본 연구 결과로부터 능실 추출물 및 분획물은 UVB에 의한 $11{\beta}-HSD1$의 발현 증가와 이에 수반하는 광노화를 효과적으로 예방함을 확인하였다.

대기 오염은 피부의 산화적 손상, 염증 및 노화를 일으킬 수 있다. 레스베라트롤은 폴리페놀 화합물의 일종으로 항산화, 항염증, 멜라닌 생성 억제 작용 등 다양한 생물학적 활성이 있는 한편 열과 빛에 약한 단점이 있다. 레스베라트릴 트라이아세테이트(RTA)는 레스베라트롤에 비해 안정하고, 피부 안전성과 미백 효능이 보고된 화장품 신소재이다. 본 연구의 목적은 직경 $10{\mu}m$ 미만 대기 미립자 물질(PM10)에 노출된 인간 표피각질형성세포(HEK)의 염증 반응에 대한 레스베라트롤과 RTA의 영향을 조사하기 위한 것이다. 배양된 HEK세포를 레스베라트롤과 RTA의 유무 조건에서 PM10에 노출시키고, 세포 생존율, 반응성 산소종(ROS)의 생성 및 염증성 사이토카인의 발현을 분석하였다. PM10을 처리하였을 때 세포 생존율이 감소하였고 종양괴사인자-${\alpha}$($TNF-{\alpha}$), 인터루킨-$1{\beta}$($IL-1{\beta}$), 인터루킨-6(IL-6) 및 인터루킨-8(IL-8)의 발현이 증가하였다. 레스베라트롤과 RTA는 PM10으로 유도된 세포의 사멸과 ROS 생성을 경감시켰다. PM10에 의해 증가되는 여러 염증성 사이토카인의 발현은 레스베라트롤과 RTA에 의해 경감되거나(IL-6), 증진되거나($IL-1{\beta}$), 변화하지 않았다($TNF-{\alpha}$ 및 IL-8). PM10에 의해 유도된 IL-6단백질의 발현이 레스베라트롤과 RTA에 의해 감소되었다. 본 연구의 결과는 레스베라트롤과 RTA가 대기 미립자 물질에 노출된 피부의 세포 손상과 염증 반응을 조절하는 작용이 있음을 시사한다.
