목적 : 전신성 홍반성 낭창(Systemic lupus erythematosus, SLE)은 여러장기를 침범하는 자가면역성 질환으로 신장의 손상이 본 질환의 예후를 좌우하는 주요원인이다. 특히 소아에서 루프스 신염은 성인보다 그 빈도가 높고, 증상이 심하므로, 신생검은 효과적인 치료의 계획을 위해서 중요한 수기이다. 이에 저자는 소아연령에서 루프스 신염의 임상적 병리학적 특성 및 치료방법에 대해 전반적으로 고찰하여 예후의 향상을 기대하고자 한다. 방법 : 1990년 1월부터 2002년 9월까지 소아과에서 전신성 홍반성 낭창으로 진단받은 63례의 환아중 신생검을 시행하여 루프스 신염으로 진단되었던 40례를 대상으로 의무 기록을 후향적으로 고찰하였다. 결과 : 환아의 남녀비는 1:3이었고 진단당시 평균발병 연령은 12.1(2-18)세였다. ARA 기준중에서는 형광 항핵항체(95.0%), 항dsDNA항체(87.5%), 나비모양 홍반(80.0%)의 순이었다. 가장 흔한 신장증상은 단백뇨와 현미경적 혈뇨(75.0%), 신증후군(55.0%), 현미경적 혈뇨 단독(15.0%)의 순이었고, 신생검상 27례(67.5%)에서 WHO Class IV 병변이 관찰되었고 3례에서 추적 관찰 신생검에서 조직소견이 바뀌었다. 치료는 prednisolone 단독 5례, prednisolone+azathioprine 9례, prednisolone+azathioprine+정맥cyclophosphamide 14례, prednisolone+cyclosporineA+정맥 cyclophosphamide 12례였고, 9례에서 혈장 교환술을 시행하였다. 환아들의 평균 추적관찰은 $51.8{\pm}40.5$개월이었고 사망은 4례에서 있었다. 사망과 관련된 위험인자로는 진단당시 성별이 남아일 때, WHO class IV의 조직소견, 급성 신부전을 동반할 때 의미있는 것으로 나타났다. 결론 : SLE 환아 중 루프스 신염의 빈도는 63.5%였으며 그중 67.5%가 예후가 불량한 WHO Class IV로 확인되었다. 따라서 신염의 초기에 적극적인 면역억제제 사용이 장기 예후 향상에 도움을 주리라고 생각된다. 하지만 소아기에 성장, 정신 사회적 발달, 생식기의 독성 등도 중요한 문제이므로 항상 적절한 치료를 위해 세심한 관심을 쏟아야 할 것이다.

The conversion of xanthine dehydrogenase (type D) into xanthine oxidase (type D) was significantly increased in serum and liver of all $CCI_4$ treated rats on the necrosis and early cirrhosis stage of liver tissue. In the pretreatment of prednisolone, the ratio of type O per type O + D showed the decreasing tendency in serum, but the significant decrease in liver. In vitro, the conversion of liver xanthine oxidase from type D into type O was markedly increased by following preincubation with lysosomal fraction. The type conversion of xanthine oxidase may be caused by protelytic enzymes in lysosome.

To clarify a cause of increased serum level of acid phosphatase in CCl$_{4}$-treated rats, the acid phosphatase activity of liver was compared with that serum. Concomitantly, the serum and liver acid phosphatase activity of CCl$_{4}$-treated rats were compared with that of CCl$_{4}$-treated rats pretreated with prednisolone or actinomycin D. In CCl$_{4}$-treated rats, the activity of serum acid phosphatase was significiantly increased whereas that of liver acid phosphatase was rather slightly decreased. the pretreatment of prednisolone led to the decreased activity of serum and liver acid phosphatase in CCl$_{4}$-treated rats. But the pretreatment of actinomycin D rather increased the activity of liver and serum enzyme. In conclusion, it is likely the increased activity of serum acid phosphatase is based on the excess leaking of acid phosphatase into blood by the increased membrane permeability of both liver cell and lysosome in it.

A 14-year-old intact female Yorkshire terrier was presented with a 2-month history of shivering, intermittent pelvic limb weakness and collapse. Biochemical abnormalities revealed inappropriately increased serum insulin concentration with persistent hypoglycemia. Abdominal ultrasound revealed multiple various sized nodules in liver and fine-needle aspirates of the nodule showed typical neuroendocrine cells with high cellularity. Computed tomography (CT) revealed well-defined hyperattenuating mass in the right pancreatic lobe with homogenous enhancement. CT findings were consistent with a pancreatic tumor with malignant metastasis. Treatment was initiated with low-dose prednisolone and toceranib phosphate. The dog was maintained stable with no more progression of clinical signs and it is worth to try toceranib phosphate in a dog with metastatic insulinoma for improving the quality of life.

항궤양약 및 진경약의 효능을 검색할 수 있는 방법을 추구하는데 목적이 있다. 항궤양약의 약효는 Shay궤양, 수침 Stress궤양, indomethacin, histamine 및 prednisolone으로 유발된 궤양에 대하여 실시하였고 진경약의 효능은 흰쥐 fundus 절편을 이용한 in vitro 방법으로 실시하였다. 그 결과 항궤양약 효능시험은 shay 궤양에 있어서 omeprazole은 10mg/kg (i.d.)의 용량에서 유의성 있는 항궤양 효과를 나타내었으며, 수침 stress궤양에서 famotidine은 0.3mg/kg(p.o.), indomethacin 궤양에서 famotidine은 3mg/kg(p.o.), histamine궤양에서 cimetidine 은 50mg/kg(p.o.), prednisolone궤양에서 cimetidine은 1mg/kg(p.o.)의 용량에서 유의성 있는 효과를 나타내었다. 또한 진경약의 약효검색에 관하여는 세신(Asarum sieboldii)의 MeOH엑스가 흰쥐 위절편(fundus) 표본에서 비상경적 진정 작용이 있음을 확인하였고, 그 작용강도는 papaverine의 1/50에 해당되나 이를 분획하였을 경우에 hexane 분획에서 papaverine의 1/2에 해당하는 강도가 있다는 결과를 얻었다.

Immunosuppressive drugs are used to make the body less likely to reject transplanted organs or to treat autoimmune diseases. In this study, five immunosuppressive drugs including two glucocorticoids (dexamethasone and prednisolone), one calcineurin inhibitor (cyclosporin A), one non-steroid anti-inflammatory drug (aspirin), and one antimetabolite (methotrexate) were tested for their effects on viral proliferation using feline foamy virus (FFV). The five drugs had different cytotoxic effects on the Crandell-Ress feline kidney (CRFK) cells, the natural host cell of FFV. Dexamethasone-pretreated CRFK cells were susceptible to FFV infection, but pretreatment with prednisolone, cyclosporin A, aspirin, and methotrexate showed obvious inhibitory effects on FFV proliferation, by reducing viral production to 29.8-83.8% of that of an untreated control. These results were supported by western blot, which detected viral Gag structural protein in the infected cell lysate. As our results showed a correlation between immunosuppressive drugs and susceptibility to viral infections, it is proposed that immune-compromised individuals who are using immune-suppressive drugs may be especially vulnerable to viral infection originated from pets.

Effects of steroid hormones on the collagen biosynthesis in aorta and uterus were studied with ovariectomized Sprague-Dawley rats. Effects of administration of hormones, such as estrogen, testosterone and prednisolone, to the ovariectomized animals were studied, comparing with the control. Each group was injected with ³H-proline and sacrificed, followed by removals of aorta and uterus. Separations and quantitative analyses of proline and hydroxyproline were performed by means of thin layer chromatography; and radioactivities of the separated amino acids were assayed by liquid scintillation counter. Normally the incorporation of ³H-proline into hydroxyproline was greater in uterus than in aorta, and collagen turnover rate of uterus was observed rapid as well than that of aorta. In the two tissues from ovariectomized rats, the incorporation rate of ³H-proline into hydroxypoline was markedly decreased than that of the former. Changes in the turnover rate of collagen in these tissues were not observed. Decrease in ³H-proline incorporation into collagen in ovariectomized rats was markedly antagonized by estrogen, but not influenced by prednisolone in the tissues tested.
