          원저 : 저산소증-허혈손상 후에 성숙한 백서의 전뇌에서 pERK1/2 단백의 발현에 관한 면역화학적 연구

          한용재 ( Yong Jae Han ), 안훈철 ( Hun Cheol Ahn ), 박재황 ( Jae Hwang Park ), 유수진 ( Su Jin Yoo ) 대한응급의학회 2008 大韓應急醫學會誌 Vol.19 No.3

          Purpose: The purpose of this study was to evaluate spatiotemporal evaluation of pERK1/2 protein expression in the forebrain following hypoxic-ischemic (HI) injury in adult Sprague-Dawley rats. Methods: HI injury was induced by occlusion of the bilateral common carotid artery (CCA) and respiration with 5% O2 hypoxic gas for 8 minutes, followed by unilateral release of CCA. Results: Immunoreactivity for pERK1/2 protein in the bilateral cortex began to increase at 2 hours, reached peak levels at 6 hours, and then decreased by 24 hours after HI injury. In a cortical neuron, the expression of pERK1/2 protein was observed in all cellular components and processes including dendrites, cell body and nuclei at 6 hours, but persisted only in the cell body by 24 hours after HI injury. Temporal changes in the immunoreactivity for pERK1/2 protein in the hippocampus was very similar to that of the cortex following HI injury. In contrast, the temporal changes in the cellular distribution of pERK12 protein in hippocampal neurons was largely different from that of the cortex following HI injury. Conclusion: The results of the present study suggest that HI injury causes an early activation of ERK1/2 signaling with a differential cellular distribution of pERK1/2 protein among different forebrain structures. Further study needs to be done in order to elucidate a possible role of ERK1/2 signaling for neural damage in the adult rodent HI model.

          원저 : 내분비-대사 ; 한국 제2형 당뇨병 남성에서 FGF-21과 비알코올성 지방간의 연관성

          한용재 ( Yong Jae Han ), 허지혜 ( Ji Hye Huh ), 성재호 ( Jae Ho Seong ), 임정수 ( Jung Soo Lim ), 이미영 ( Mi Young Lee ), 정춘희 ( Choon Hee Chung ), 신장열 ( Jang Yel Shin ) 대한내과학회 2015 대한내과학회지 Vol.88 No.3

          목적: 혈청 FGF-21의 증가는 비만, 대사증후군, 제2형 당뇨병을 가진 환자에서 관찰되었으나 현재까지 제2형 당뇨병환자에서 NAFL과 FGF-21의 연관성은 확실하게 정립되어 있지 않다. 이에 저자들은 제2형 당뇨병을 가진 한국인 남성환자에서 혈중 FGF-21 수치와 NAFL의 연관성을 확인하고 혈중 FGF-21 수치에 영향을 미치는 독립적 위험인자를 알아보고자 하였다. 방법: 제2형 당뇨병으로 진단 받은 한국인 성인 남자 135명 (평균 56.2 ± 9.2세)을 대상으로 하였다. 임상 및 생화학적 대사 지표를 측정했고 혈청 FGF-21은 ELISA를 이용하여 측정했다. NAFL의 정도는 복부 초음파 검사를 통해 진단했으며 간 내 혈관 경계와 횡격막이 희미하게 보이거나 또는 보이지 않으면서 간 실질의 초음파 음영이 두드러지게 증가한 경우를 중등도 이상의 지방간으로 판정하였다. 결과: 정상간을 가진 환자에 비해 중등도 이상 지방간을 가진 환자에서 BMI, 허리둘레, HOMA-IR, TG, 간효소 및 혈청 FGF-21 수치가 유의하게 증가되어 있었다. 혈청 FGF-21은 BMI, 혈청 Cr, TG, 간효소 수치, 그리고, hsCRP와 양의 상관관계를 갖고, HDL 콜레스테롤과 음의 상관관계가 관찰되었다. 다변량 선형 회귀분석에서 TG, 중증도 이상의 지방간 그리고 혈청 Cr만이 FGF-21 농도와 통계학적으로 유의한 양의상관관계를 보였다. 로지스틱 회귀분석에서도 중등도 이상지방간 동반의 위험도는 혈청 Cr, TG, BMI 그리고 HOMA-IR을 보정하고 난 이후에도 혈청 FGF-21과 통계적으로 유의했다. 결론: 본 연구는 제2형 당뇨병을 가진 한국 남자 환자에서 NAFL과 혈중 FGF-21 농도가 독립적인 연관성이 있음을 확인했다. Background/Aims: Serum fibroblast growth factor-21 (FGF-21) levels are elevated in obesity, metabolic syndrome, and type 2 diabetes. Clinical studies have demonstrated an association between FGF-21 and nonalcoholic fatty liver (NAFL) in the general population. This study investigated the association between FGF-21 and NAFL in Korean men with type 2 diabetes. Methods: Clinical and biochemical metabolic parameters were measured in 135 Korean men with type 2 diabetes (mean age: 56.2 ± 9.2 years; HbA1C: 7.6 ± 1.5%). Serum FGF-21 was determined by enzyme-linked immunosorbent assay. NAFL severity was assessed by ultrasound of the liver. High-grade (hg) NAFL was defined as moderate or severe fatty liver. Results: The patients were divided into three subgroups according to NAFL severity: normal (17.0%), low-grade (50.4%), and high-grade (32.6%). Patients with hgNAFL had a larger waist circumference and higher body mass index (BMI), homeostatic model assessment-estimated insulin resistance (HOMA-IR) score, and triglyceride (TG), liver enzyme, and FGF-21 levels than those with a normal liver. FGF-21 correlated positively with BMI, serum creatinine (Cr), TG, liver enzymes, and high-sensitivity C-reactive protein, but negatively with high density lipoprotein (HDL). In multivariate regression analysis, Cr and TG were independently associated with FGF-21. BMI, TG, HDL, HOMA-IR, and FGF-21 correlated strongly with hgNAFL. The odds ratio (OR) of a 1-standard-deviation increase in FGF-21 predicting hgNAFL was 2.39 (95% confidence interval, 1.55?3.68). The OR remained significant after adjustment for Cr, TG, BMI, and HOMA-IR. Conclusions: Our findings suggest an independent association of serum FGF-21 with NAFL in Korean men with type 2 diabetes.
