목 적 : 급성 허혈성 신손상 후 손상된 세뇨관 상피세포의 재생은 순환하거나 국소적으로 생성된 성장인자나 cytokine, 생리적 인자 및 주위 환경들의 조절에 의해 매개되는 것으로 알려져 있다. 따라서 급성 허혈성 신손상 후 신기능 회복에 따른 혈중 IGF-I의 변화와 전체 신장조직과 각 부위에 따른 IGF-I, -II, VEGF, $TGF-{\beta}1$, CTGF의 mRNA 발현의 변화를 알아보는데 연구의 목적이 있다. 방 법 : 체중이 250-300 g의 백서를 대상으로 급성 허혈성 신손상을 시켜 유발된 급성 신부전 모델을 이용하여 급성 신부전의 진행과정에 따라 혈청 IGF-I치와 여러 성장인자 발현의 변화를 측정하였다. 급성 신부전 진행은 혈청 크레아티닌을 측정하여 평가하였고 혈청 IGF-I 농도는 iodinated IGF-I과 polyclonal anti-IGF-I 항체를 이용한 방사면역 측정법을 이용하여 측정하였다. 신장에서 성장인자의 발현은 RT-PCR을 이용하였고 신장조직에서의 RNA 추출은 통상적인 방법에 준하였다. 신장에서의 IGF-I과 CTGF의 분포는 anti-IGF-I 항체와 anti-CTGF 항체를 이용한 면역조직화학법을 이용하였다. 결 과 : 1) 양측 신동맥을 결찰한 후 1일째부터 체중 감소와 혈청 크레아티닌치의 증가가 관찰되었는데 이러한 변화는 3일째에 가장 현저하였다. 혈청 IGF-I은 신손상 후 1일 째 현저하게 감소하였고 신손상 3일째에 더 증가되었다가 5일째부터는 신손상 전으로 회복되었다. 2) 신기능 회복에 따른 성장인자의 변화는 거의 유사하였다. IGF-I, IGF-II, $TGF-{\beta}1$ 및 VEGF의 mRNA 발현은 허혈성 신손상 후 1일째에 현저하게 감소하였고 신손상 3일째에는 신손상 전에 비해 증가하였으며 7일째에는 거의 신손상 전의 수준으로 회복되었다. 3) IGF-I과 IGF-II는 정상 신장에서는 주로 수질부 특히 바 깥쪽 수질부에서 발현되었고 허혈성 신손상 1일째에 현저하게 감소하였다가 3일째에는 정상 수준으로 회복되었다. $TGF-{\beta}1$은 정상에서 신수질부에서 주로 발현되었고 1일째는 현저하게 감소하였다가 회복되는 소견을 보였다. CTGF와 VEGF는 정상 신장의 수질부와 피질부 모두에서 발현되었으며 신손상 1일째에 현저하게 감소되었다가 3일째부터 정상 수준으로 회복되는 소견을 보였다. 4) 정상 백서의 신장에서 IGF-I은 주로 피질부위의 신세뇨관에 분포하였고 사구체에서는 발견되지 않았는데 급성 허혈성 신손상 후 1일째 신장의 피질부위에서는 IGF-I가 현저히 감소되었다. CTGF는 정상 백서의 신장에서는 주로 혈관에 분포하는 소견을 보였는데 신손상 3일째에는 세뇨관에서 현저한 증가가 관찰되었다. 결 론: 이번의 연구로 저자들은 IGF-I, IGF-II, $TGF-{\beta}1$, CTGF, VEGF 등과 같은 성장인자가 급성 허혈성 신손상 후 신기능과 세뇨관세포의 회복과정에 발현의 변화가 초래된다는 사실을 알 수 있었다. 따라서 신기능 회복을 촉진시키기 위해 여러 성장인자를 급성신부전 치료제로 사용할 수 있을 것으로 생각되고 이에 대한 연구가 더 필요할 것으로 생각된다.

Objectives Alismatis Rhizoma has been known to suppress inflammation and allergic reaction. However, the cellular target of Alismatis Rhizoma and its mechanism of action remain unclear. This study was designed to examine the effect of Alismatis Rhizoma extract (ALC) on the RBL-2H3 mast cells in vitro and on the OVA/alum sensitized mice ex vivo. Methods In the study, RBL-2H3 mast cells were cultured in minimal essential medium (MEM) for 24 hours, and treated separately with cyclosporin A and varying doses of ALC, and then stimulated with Phorbol 12-myristate 13-acetate (PMA) (50 ng/ml) and Ionomycin ($0.5{\mu}M$). The levels of IL-13, IL-4 were measured by ELISA analysis. The mRNA levels of IL-4, IL-5, IL-6, IL-13, GM-CSF, $TNF-{\alpha}$ were analyzed with Real-time PCR. Also, manifestations of MAPKs transcription factors and $NF-{\kappa}B$ p65 translocation were analyzed by western blotting in vitro. Subsequently, for ex vivo experiment, we induced allergic inflammation on Balb/c mice by OVA/alum and administered ALC orally. And we measured serum OVA-specific IgE level and IL-4, IL-13 in the splenocyte culture supernatant by ELISA analysis. Results ALC was shown to suppress mRNA expression of IL-4, IL-5, IL-6, IL-13, GM-CSF, $TNF-{\alpha}$, and to inhibit the IL-13, IL-4 production. Also ALC reduced an activation of mast cells specific signal MAPKs transcription factors and $NF-{\kappa}B$ p65 from the western blot analysis in in vitro experiment. In ex vivo, ALC oral adminstration decreased the level of OVA-specific IgE in serum, and IL-4, IL-13 in the splenocyte culture supernatant. Conclusions ALC is shown to reduce inflammation and allergic response by suppressing Th2 cytokines through the regulation of transcription factors MAPKs and $NF-{\kappa}B$ p65 in mast cells. Administration of ALC suppressed OVA-specific IgE in ovalbumin allergy model through the inhibition of Th2 cytokine. In conclusion, ALC can be considered as an effective treatment for allergic diseases such as atopic dermatitis.

Objectives : Nitric oxide (NO) plays an important role in normal and pathophysiological cells as a messenger molecule, neurotransmitter, microbiological agent, or dilator of blood vessels and arteriosclerosis, respectively. This study was undertaken to understand the mechanism of NO production and effect of Hyeolbuchukeo-tang (Xiefuzhuyu-tang) on NO production in cultured vascular smooth muscle cell (VSMC). Methods and Results : VSMC was isolated from aorta and cultured. Cultured primary cells were identified as VSMC with anti--smooth muscle actin antibody. A large amount of NO was produced in cultured VSMC treated with $IFN-{\gamma}$ plus TNF in a time- and dose-dependent manner. $TNF-{\alpha}$ was a more efficient stimulator than $IFN-{\gamma}$ in NO production of cultured VSMC. iNOS protein wasdetected within 3 hrs and it increased up to 12 hrs in a time-dependent manner. However, accumulated NO in cytokine-treated VSMC was not detected within 3 hrs. NO production in cytokine-treated VSMC showed the dose- and time-dependent manner, and increased up to 48 hrs. The activated VSMC produced a large amount of NO (about 60 uM). Hyeolbuchukeo-tang (Xiefuzhuyu-tang) alone did not induceNO production, but it potentiated the effect of $TNF-{\alpha}$ on NO production and increased NO production by about 20%. Hyeolbuchukeo-tang (Xiefuzhuyu-tang) did not affect the transcriptional activity of iNOS gene, but increased the accumulation of iNOS. These results indicate that Hyeolbuchukeo-tang (Xiefuzhuyu-tang) could modulate the translational level of iNOS. PKC did not modulate NO production, but calcium ionophore A23187 decreased NO production. However, Hyeolbuchukeo-tang (Xiefuzhuyu-tang) elevated the decreased NO production in A23187-treated VSMC by modulating the stability of iNOS transcripts. Half-life of the synthesized transcripts appeared to have about 6 hrs. PDTC, an $NF-{\kappa}B$ inhibitor, blocked the accumulation of iNOS mRNA, indicating that $NF-{\kappa}B$ served as an important modulator in the transcriptional regulation of iNOS. As Hyeolbuchukeo-tang (Xiefuzhuyu-tang) potentiated the effect of the $TNF-{\alpha}$ on NO production but had no additional effect on PDTC-modulated NO production, it is suggested that Hyeolbuchukeo-tang (Xiefuzhuyu-tang) enhances the $TNF-{\alpha}-mediated$ NO production of VSMC by modulating the iNOS activity and the stability of iNOS transcripts in activated VSMC having the elevated intracellular calcium ion. Conclusions : This study suggests that Hyeolbuchukeo-tang (Xiefuzhuyu-tang) has a potential capacity for preventing and treating diseases of the circulation system, including arteriosclerosis.

Bangpungtongseong-san(BPTSS, Fangfengtongsheng-san in Chineses) is a traditional herbal formula comprising 18 medicinal herbs. In the present study, we performed the simultaneous analysis for four compounds of BPTSS and examined anti-allergic effects in human keratinocytes and mouse splenocytes. The column for separation of four compounds was used Luna C18 column and maintained at 40℃. The mobile phase for gradient elution consisted of two solvent systems. The analysis was carried out at a flow rate of 1.0 mL/min with PDA detection at 254 and 280 nm. To evaluate production and expression of Th2 chemokines, ELISA and RT-PCR were conducted in tumor necrosis factor (TNF)-α and interferon (IFN)-γ-stimulated HaCaT cells with or without BPTSS or silymarin, a positive control for skin inflammation. To measure Th2 cytokines, primary mouse splenocytes were treated with BPTSS and performed ELISA for interleukin (IL)-4, 5, 13. Calibration curves were acquired with r2>0.9999. The contents of geniposide, liquiritin, baicalin, and glycyrrhizin in BPTSS were 5.06 ㎎/g, 7.33 ㎎/g, 27.56 ㎎/g, and 7.81 ㎎/g, respectively. BPTSS reduced TARC and RANTES production and mRNA expression in TNF-α and IFN-γ-treated HaCaT cells. BPTSS inhibited IL-4, 5, and 13 production in mouse splenocytes. Our data will be a helpful information to upgrade quality control and anti-allergic effects of BPTSS.
