        Food irradiation has been steadily increased in many countries concomitantly with increasing international trades. Harmful contaminants naturally occurred from foods which contain high levels of unsaturated fatty acids that are easily oxidized can affect the human anti-oxidation system through the generation of free radicals. Moreover, previous studies proved that r-irradiation may cause production of free radicals in food. We investigated the effect of r-irradiated soybeans in relation to oxidative stress in mice. Oxidative index of mice was evaluated by TBARS, DNA fragmentation in various organs such as blood lymphocytes, liver and kidney. Forty male ICR mice were equally divided into 4 groups and fed control diet or r-irradiated diet containing 50% soybeans (5, 10, and 20 kGy, respectively) for 8 weeks. Peroxide values of the irradiated diets were higher than that of the non-irradiated one and increased according to the storage period. There was no significant difference in weight gain as well as in TBARS value in plasma and kidney of all groups. Liver TBARS value of the group fed with irradiated diet at 20 kGy increased significantly compared with the control group (p<0.05). DNA oxidative damage as measured by alkaline comet assay showed that % tail DNA in the blood lymphocytes of 5 kGy and 10 kGy groups increased significantly over the control group (p<0.05). Also, tail moments of 5 kGy and 10 kGy groups were higher than that of the control group. Ultrastructural examination shows myeline figures and swollen mitochondria in parietal and intestinal epithelial cells of the group fed with irradiated diet. Therefore, considering unsaturated fatty acid content, consumption of soybeans r-irradiated with over 20 kGy or repeatedly may decrease the body's antioxidant mechanism.

        저자들은 비전격성 형태로 발현된 급성 A형 간염으로 인한 급성 신부전을 경험하였다. 환자의 임상 경과와 병리 소견을 알기 위해 실시한 신조직 검사에서 급성 신부전의 특징적인 조직 소견인 급성 신세뇨관 괴사를 확인하였고, 광학 현미경 소견에서 IgA신병증 그리고 면역 형광 염색에서 과막증식 사구체 신염을 확인하여 역으로 만성 B형 간염으로 인한 신병증도 함께 진단할 수 있었다. 이후 실시한 혈액 투석으로 신기능이 회복된 예를 경험하였기에 이를 보고하는 바이며 이런 환자에서 특별한 금기가 없는 한 신조직 검사를 실시하는 것이 환자의 임상경과를 알고 치료하는데에 도움이 된다 하겠다. Hepatitis A is usually a self-limited liver disease that is treated conservatively. Acute renal injury complicating acute hepatitis A in the absence of fulminant hepatic failure is rare. We experienced a 33-year-old man who was healthy, and did not know that he was a hepatitis B virus (HBV)carrier with non-fulminant hepatitis A. He developed an acute kidney injury that necessitated dialysis therapy and a renal biopsy. He recovered within about 1 month. Pathologically, the renal biopsy showed acute tubular necrosis. It also showed IgA nephropathy and mesangium proliferation with glomerular nephritis, which are seen in chronic viral hepatitis B. We describe the association of acute hepatitis A with acute kidney injury and report the pathological findings of a renal biopsy related to chronic hepatitis B in an acute hepatitis A patient discovered by chance.

        빈기태(Ki Tai Bin),나기량(Gi Ryang Na),오선미(Seoun Mee Oh),김종섭(Jong Sub Kim),김성숙(Seong Suk Kim),이강욱(Kang Wook Lee),신영태(Young Tai Shin),서광선(Kwang Sun Seo),이정호(Jeong Ho Lee) 대한내과학회 1996 대한내과학회지 Vol.51 No.6

        N/A Objectives: IgA nephropathy is the commonest glomerulonephritis in the world. In contrast to initial report indicated a favorable prognosis, subsequent reports have shown a highly variable outcome leading to end-stage renal failure in significant proportion of patients. Because IgA nephropathy is a disease with variable rate of progression to chronic renal failure, identification of clinical and pathologic prognostic indicators for these patients is very important. Methods: To evaluate the clinical features of IgA nephropathy and clinicopathological parameters that are associated with deteriorated renal function, we analyzed retrospectively 149 patients who were diagnosed as IgA nephropathy at Chungnam National University Hospital from January, 1986 to June, 1994. We also evaluated the clinicopathological fin- dings of 23 patients who were followed for more than 36 months in order to determine the prognostic signigificance of various renal histopathological alterations and clinical parameters, Results: l) IgA nephropathy was disgnosed to 149 patients(26.5%) for same period among 565 biopsied patients. 2) It is most common in the 3rd and 4th decades. The mean age of the patients was 28.9 years, and male to female ratio ratio was 1: 1,25. 3) Fifty two percents of the patients presented with gross hematuria. Upper respiratory tract infection preceded grosss hematuria in 85% of the patients. 4) At the time of renal biopsy, 9,4% of the patients showed heavy proteinuria and nephrotic syndrome, 5) In Comparison of clinicopathological parameters between 14 patients with normal renal function and 9 patients with deteriorated renal function who had a follow-up period of more than 36 months, the results of the findings are as follows: 24 hours total urine protein more than 2.0 grams, elevated BUN and serum creatinine concentration and severe degree of renal histopathologic findings, such as mesangial proliferation and sclerosis, interstitial fibrosis and tubular atrophy showed poor prognostic results. Conclusion: Clinical features such as 24 hours total urine protein more than 2 grams, higher serum blood urea nitrogen and serum creatinine and severe degree of histopathologic features such as mesangial proliferation and sclerosis, interstitial fibrosis and tubular atrophy were associated with deteriorated renal function.

      • 특발성 및 이차성 막성 신병증의 임상적 및 병리학적 고찰

        서광선 충남대학교 의과대학 지역사회의학연구소 1991 충남의대잡지 Vol.18 No.2

        A clinicopathological analysis for 83 cases of membranous nephropathy(MN) has been carried out from a series of renal biopsy specimens which were studied at Department of Pathology, College of Medicine, Chungnam National University, during a period of 8 years from October 1983 to September 1991. The following results were obtained : 50 cases(60.2%) were classified as an idiopathic MN and 33 cases(.39.8%) had an associated condition, such as hepatitis B virus or hepatitis C virus infection 18 cases(54.5%), systemic lupus erythematosus 9 cases(27.3%), pulmonary tuberculosis 3 cases(9.1%), syphilis 2 cases(6.1%), and diabetes mellitus 1 case (3.0%). The latter group was considered as a secondary MN. Although secondary MN is generally indistinguishable in all categories from idiopathic MN, on comparison of histopathologic features, it can be concluded that the following findings such as mesangial proliferation, mesangial expansion, deposits in multiple(mesangial and subendothelial) sites, and predominant IgA deposits are characteristic of secondary MN.

      • 자발적 초점성분절성사구체경화증 Mouse 모델에서 TGF-β및 MCP-1 유전자발현에 미치는 Renin Angiotensin System 의 영향에 관한 연구

        신영태,서광선,이강욱 충남대학교 의과대학 지역사회의학연구소 1999 충남의대잡지 Vol.26 No.1

        The role of angiotensin Ⅱ in the pathogenesis of the progressive renal injury process has been studied in many human renal diseases and animal renal injury models. The inhibition of angiotensin Ⅱ also has been reported to be effective to attenuate renal injury process in many human renal diseases and animal models. The activation of TGF-β and MCP-1 gene is thought to be related with renal injury process. A mutant strain FGS/Nga/Kist mouse is reported to develop focal and segmental glomerulosis, spontaneously. In order to evaluate renal pathology, MCP-1 and TGF-β gene expressions and the effect of renin-angiotensin system inhibition, 8 FGS/Nga/Kist mice were treated by angiotensin converting enzyme inhibitor, enalapril (150 mg/L in drinking water) for 12 weeks. Another non-treated, agematched 8 FGS/Nga/Kist mice and 6 nomal CBA/Nga mice were also included in this study. The urinary protein excrtion, magnitude of glomerular sclerosis, and renal express of MCP-1 and TGF-β were evaluated by uristick, light microscopic examination and competitive RT-PCR, respectively. CBA/Nga mice did not show significant proteinuria. However, urinary protein scores of enalapril-treated FgS/Nga/Kist mice was significantly lower than that of non-treated FGS/Nga/Kist mice (2.0±0.3, 4.1±0.5, respectively, p <0.05). Focal and segmental glomerular scierosis index of enalapril treated FGS/Nga/Kist mice was significantly lower than that of non-treated FGS/Nga/Kist mice (120±13, 189±15, respectively, p < 0.05). The level of renal TGF-β gene expression of enalapril treated FGS/Nga/Kist was significantly higher than that of CBA/Nga mice (4.7±1.3, 1.0±0.3, respentively, p< 0.05). But, enalapril treated FGs/Nga/Kist mice showed significantly lower level of TGF-β expression than that of non-treated FGS/Nga/Kist mice(p<0.05). MCP-1 gene expression of untreated FGS/Nga/Kist mice was significantly lower than that of CBA/Nga mice. However, enalapril treated FGS/Nga/Kist mice showed markedly increased level of MCP-1 gene expression compared to the untreated FGS/Nga/Kist mice(9.8±1.8, 3.6±1.2, respectively, p<0.05). With the above result, we speculate that angiotensin converting enzyme ingibition attenuates the renal injury process in this model and the regulation pathway of MCP-1 by renin-angiotensin system may be different from other animal renal injury models.

      • 일측 요관폐쇄에 의한 실험적 수신증에서 신조직내 MCP-1 및 TNF-α유전자 발현

        나가량,황평주,김종학,구영선,강민규,서광선,이강욱,신영태 충남대학교 의과대학 지역사회의학연구소 1999 충남의대잡지 Vol.26 No.2

        Early cellular and molecular derangements have been suggested as potential pivotal factors for the development of renal injury, such as interstitial fibrosis after the experimental hydronephrosis. Several recent studies have been demonstrating that one of the initial events taking place in the progressive renal injury process is the mononuclear cell infiltration in the glomeruli and tubulointerstitiuim. In order to evaluate the renal light microscopic findings as well as the renal cortical MCP-1 and TNF-α gene expressions which are modulating inflammatory process and the recruitment of mononuclear cells in many experimental models of renal injury, Sprague-Dawley rats underwent unilateral ureteral obstruction (UUO) and sham operation under the thiopental sodium anesthesia(50 mg/kg intraperitoneal injection). Three and 7 days after surgery, rats were sacrificed. By the competitive RT-PCR, the levels of TNF-α and MCP-1 mRNA in renal cortical tissues were measured. The magnitude of mononuclear cell infiltration and interstitial widening were evaluated by standard point counting method. The level of MCP-1 gene expression was significantly increased in UUO group compared to sham group at 3 and 7 days after surgery(UUO 3 days 8.99 ± 0.45, UUO 7 days 11.2 ± 0.26, sham 3 days 1.00 ± 0.08, sham 7 days 0.94 ± 0.05, p < 0.01, p < 0.01, mean ± SEM, respectively). The level of MCP-1 mRNA at 7 days after surgery was significantly higher than that at 3 days in UUO group. The TNF-α gene expression level of UUO group was also significantly higher than that of sham group at 3 and 7 days after surgery(UUO 3 days 1.73 ± 0.16, UUO 7 days 2.03 ± 0.21, sham 3 days : 1.00 ± 0.06, sham 7 days 1.09 ± 0.03, p < 0.01, p < 0.01, respectively). But there was no significant difference between the levels at 3 and 7 days after surgery in UUO group(p>0.05). On the light microscopic examination, the relative volume of interstitium (RVI) and the total count of infiltrated mononuclear cells(MCC) at 3 and 7 days after surgery in UUO group were also significantly higher than those of sham group(RVI ; UUO 7 days 14.9±1.0%,sham 6.0±0.7%, MCC; UUO 7days 34.0± 1.6, sham 3.7± 0.6, p < 0.01, p < 0.01, respectively). In conclusion, we speculated that the early up-regulation of MCP-1 and TNF-α genes of renal cortical tissue in this experimental hydronephrosis model is closely related to the mononuclear cell infiltration and tubulointerstitial fibrosis.
