본 연구는 국민건강영양조사 2015년부터 2018년도 자료를 활용하여 우리나라 만 19세 이상 성인의 KHEI와 복부비만의 관련성 및 hs-CRP의 매개 효과를 분석한 연구이다. 한국 성인 남성의 경우 허리둘레 90 cm 이상, 여성은 허리둘레 85 cm 이상인 경우에 복부비만군으로 정의하였다. 남성에서 복부비만군은 2,587명, 정상군은 5,007명이였고 여성의 복부비만군은 2,869명, 정상군은 7,307명이였다. KHEI, hs-CRP, 복부비만의 연관성 분석에서는 모든 공변량을 보정하였을 때 남성의 KHEI는 복부비만과 유의한 연관이 없었지만, hs-CRP와 음의 연관성이 있었다. 여성의 경우, 복부비만과 hs-CRP 모두 음의 연관성이 관찰되었다. 또한, 남성과 여성에서 hs-CRP 위험군 (> 1.0 mg/L) 이 hs-CRP 정상군 (≤ 1.0 mg/L)보다 복부비만 유병률이 유의하게 높았다. Bootstrapping을 이용한 매개효과 분석에서는 KHEI와 복부비만 관계에서 hs-CRP가 매개 효과를 가지는 것으로 나타났으며 공변량을 단계적으로 보정하였을때 증가하는 양상이 나타났다. 결론적으로, 본 연구 결과는 균형잡힌 식생활를 통한 높은 식사의 질이 hs-CRP에 영향을 미쳐 복부비만 예방에 중요한 영향을 미칠 수 있음을 시사한다.

Chijabaegpi-tang (CHG) is an oriental herbal medicine that has been used for its various pharmacological effects, which include anti-inflammatory, anti-oxidant and immunoregulation activities. In the present study, we investigated which skin inflammations are involved in the $TNF-{\alpha}/IFN{\gamma}$-induced HaCaT cells. We investigated the suppressive effect of CHG on $TNF-{\alpha}/IFN{\gamma}$-induced HaCaT cell production of the following chemokines: macrophage-derived chemokine (MDC)/CCL22; regulated on activation, normal T-cell expressed and secreted (RANTES)/CCL5; and interleukin-8 (IL-8); thymus and activation-regulated chemokine (TARC)/CCL17. The pre-treatment of HaCaT cells with CHG suppressed $TNF-{\alpha}/IFN{\gamma}$-induced nuclear transcription factor kappa-B ($NF-{\kappa}B$). In addition, CHG inhibited $TNF-{\alpha}/IFN{\gamma}$-induced phosphorylation of ERK and p38. $TNF-{\alpha}/IFN{\gamma}$ suppressed the expression of skin barrier proteins, including filaggrin (FLG), Involucrin (IVL) and loricrin (LOR). By contrast, CHG restored the expression of FLG, IVL and LOR. Taken together, our findings suggest that CHG could be a therapeutic agent for prevention of skin disease, including atopic dermatitis.

The intracellular parasite Babesia microti is among the most significant species causing human babesiosis and is an emerging threat to human health worldwide. Unravelling the pathogenic molecular mechanisms of babesiosis is crucial in developing new diagnostic and preventive methods. This study assessed how priming with B. microti surface antigen 1 (BHSA 1) and seroreactive antigen 5-1-1 (BHSA 5-1-1) mediate protection against B. microti infection. The results showed that 500 ㎍/ml rBMSA1 and rBMSA5-1-1 partially inhibited the invasion of B. microti in vitro by 42.0±3.0%, and 48.0±2.1%, respectively. Blood smears revealed that peak infection at 7 days post-infection (dpi) was 19.6%, 24.7%, and 46.7% in the rBMSA1, rBmSA5-1-1, compared to the control groups (healthy mice infected with B. microti only), respectively. Routine blood tests showed higher white blood cell, red blood cell counts, and haemoglobin levels in the 2 groups (BMSA1 and BMSA5 5-1-1) than in the infection control group at 0-28 dpi. Moreover, the 2 groups had higher serum interferon-γ, tumor necrosis factor-α and Interleukin-17A levels, and lower IL-10 levels than the infection control group throughout the study. These 2 potential vaccine candidate proteins partially inhibit in vitro and in vivo B. microti infection and enhance host immunological response against B. microti infection.

Yukmijihwang-tang has been widely used as an and-aging herbal medicine for hundred years in Asian countries. Numerous studies show that Yukmijihwangtang has anti-oxidative effect both in vivo and in vitro. It has been reported that Moutan Cortex Radicis extract (MCR) was the most effective herb in Yukmijihwang-tang on undifferentiated PC12 cells upon oxidative-stressed with hydrogen peroxide. The purpose of this study is to; 1) evaluate the recovery of neuronal damage by assessing the anti-oxidant effect of MCR on PC12 cells differentiated with nerve growth factor (NGF), 2) identify candidate genes responsible for anti-oxidative effect on differentiated PC12 cells by oligonucleotide chip microarray. PC12 cells, which were differentiated by treating with NGF, were treated without or with hydrogen peroxide in the presence or absence of various concentration of MCR. Cell survival was determined by using MTS assay. Measurement of intracellular reactive oxygen species (ROS) generation was determined using the H2DCFDA assay The viability of cells treated with MCR was significantly recovered from stressed PC12 cell. In addition, wide rage of concentrations of MCR shows dose-dependent inhibitory effect on ROS production in oxidative-stressed cells. Total RNAs of cells without treatment(Control group), only treated with H₂O₂ (stressed group) and treated with both H₂O₂ and of MCR (MCR group) were isolated, and cDNAs was synthesized using oligoT7(dT) primer. The fragmented cRNAs, synthesized from cDNAs, were applied to Affymetrix GeneChip Rat Neurobiology U34 Array. mRNA of Calcium/calmodulin-dependent protein kinase II delta subunit(CaMKII), neuron glucose transporter (GLUT3) and myelin/oligodendrocyte glycoprotein(MOG) were downregulated in Stressed group comparing to Control group. P2X2-5 receptor (P2X2R-5), P2X2-4 receptor (P2X2R-4), c-fos, 25 kDa synaptosomal attachment protein(SNAP-25a) and GLUT3 were downregulated, whereas A2 adenosine receptor (A2AR), cathechol-O-methyltransferase(COMT), glucose transporter 1 (GLUT1), EST223333, heme oxygenase (HO), VGF, UI-R-CO-ja-a-07-0-Ul.s1 and macrophage migration inhibitory factor (MIF) were upregulated in MCA group comparing to Control group. Expression of Putative potassium channel subunit protein (ACK4), P2X2A-5, P2X2A-4, Interferon-gamma inducing factor isoform alpha precursor (IL-18α), EST199031, P2XR, P2X2 purinoceptor isoform e (P2X2R-e), Precursor interleukin 18 (IL-18) were downregulated, whereas MOO, EST223333, GLUT-1, MIF, Neuronatin alpha, UI-R-C0-ja-a-07-0-Ul.s1, A2. adenosine receptor, COMT, neuron-specific enolase (NSE), HO, VGF, A rat novel protein which is expressed with nerve injury (E12625) were upregulated in MCR group comparing to Stressed group. The results suggest that decreased viability and AOS production of PC12 cell by H₂O₂ may be, at lease, mediated by impaired glucose transporter expression. It is implicated that the MCR treatment protect PC12 cell from oxidative stress via following mechanisms; improving glucose transport into the cell, enhancing expression of anti-oxidative genes and protecting from dopamine cytotoxicity by increment of COMT and MIF expression. The list of differentially expressed genes may implicate further insight on the action and mechanism behind the anti-oxidative effects of herbal extract Moutan Cortex Radicis.
