Lupus erythematous panniculitis is a chronic inflammatory disease of subcutaneous fat that occurs in 2-3% of patients with systemic lupus erythematosus. Lupus erythematous panniculitis typically presents with firm, indurated subcutaneous nodules or plaques commonly developed in proximal extremities, trunks, head and neck. Face, breast and upper extremities involvement with lupus erythematous panniculitis has been infrequently reported. We report a case of lupus erythematous panniculitis developed in a 27-year-old female confirmed by histologic features and laboratory findings.

Purpose: Because studies about the control of penile erection at the entral nervous system was dependent on the animal experiments, establishment of measuring penile erection is important to evaluate the effects changes at the central nervous system on the penile erection. Intracavernous pressure measurement in rats has been introduced as a suitable index for the evaluation of penile erection but this method is invasive and technically difficult. So, we established the intracavernous pressure measurement in rats as the experimental index for penile erection. Materials and Methods: 42 male adult Sprague-Dawley rats (250-300gm) were divided to saline or papaverine treated group. Rats were placed on a heating table to maintain their body temparature and anesthetized with 50mg/kg of pentobarbital sodium by intraperitoneal injection. A cannula was inserted to the left carotid artery to measure systemic blood pressure. Saline (0.05, 0.1ml), papaverine(0.05, 0.1, 0.25, 0.5, 1.0, 2.0mg) were injected intracavernously via 26 guage needle filled with saline or papaverine which connected to pressure transducer and polygraph was inserted into the corpus cavernosum on one side to inject the drug and to measure intracavernous presure. Results: Properly executed insertion and intracavernous administration produced a instantaneous but transient rise in intracavernous pressure that substantially stabilized and maintained at 5.4±0.4mmHg. Intracavernous pressure and duration of penile blood flow following intracavernous injection of papaverine are increased comared to those of saline. Conclusions: Monitoring intracavernous pressure in rats represents a suitable index for the evaluation of penile erection in small laboratory animals.

Purpose : The Mirizzi syndrome is relatively rare and preoperative diagnosis of this disease is difficult. In 1978, Morelli suggested the subclassification of the Mirizzi syndrome into acute or chronic form. We experienced 5 cases of acute form. We analysed clinical features, preoperative radiologic findings and operative findings of 18 cases including acute forms which were diagnosed as Mirizzi syndrome and should suggest the modified classification of Mirizzi syndrome for choice of appropriate treatment. Method : From January 1995 to December 1998, 18 cases, of which 8 cases were diagnosed at Soonchunhyang University Chunan Hospital, and 10 cases were reported in the Korean Journal were retrospectively analysed with regard to clinical features, preoperative radiologic findings and operative findings. According to the clinical features, whole cases were divided into type Ⅰ(acute form) and type Ⅱ(chronic form) and then each type of cases were subclassified according to preoperative radiologic findings and operative findings. Results : Of 18 cases there were 5 cases in type Ⅰ(27.8%), 13 cases in type Ⅱ(72.2%). Type Ⅱb was most common. Type Ⅰa cases were treated only with cholecystectomy. We applied cholecystectomy, T-tube choledochostomy and patch technique in type Ⅰb and thpe Ⅰc cases. Cholectystectomies including removal of gallstones and internal drainage procedures were done in type Ⅱ chronic forms. Conclusion : The acute form(Type Ⅰ) of Mirizzi syndrome was suggested by Morelli might be subclassified into typeⅠa,Ⅰb and Ⅰc following the presence of the necrotic defect in common hepatic duct. Through the modified classification of Mirizzi syndrome based on clinical feature, preoperative radiologic findings and operative findings, we can choice appropriate treatment.

Calcium concentration in the bone resorption lacunae is high and is in the mM concentration range. Both osteoblast and osteoclast have calcium sensing receptor in the cell surface, suggesting the regulatory role of high extracellular calcium in bone merabolism. In vitro, high extracellular calcium stimulated osteoclastogenesis in coculture of mouse osteoblasts and bone marrow cells. Therefore we examined the genes that were commonly regulated by both high extracellular calcium and 1,25(OH)_(2)vitaminD_(3)(VD3) by using mouse oligo 11 K gene chip. In the presence of 10 mM[Ca^(2+)]e or 10 nM VD3, mouse calvarial osteoblasts and bone marrow cells were co-cultured for 4 days when tartrate resistant acid phosphatase-positive multinucleated cells start to appear. Of 11,000 genes examined, the genes commonly regulated both by high extracellular calcium and by VD3 were as follows; 1) the expressions of genes which were osteoclast differentiation markers or were associated with osteoclastogenesis were up-regulated both by high extracellular calcium and by VD3; trap, mmp9, car2, ctsk, ckb, atp6b2, tm7sf4, rab7, 2) several chemokine and chemokine receptor genes such as sdf1, scya2, scyb5, scya6, scya8, scya9, and ccr1 were up-regulated both by high ectracellular calcium and by VD3, 3) the genes such as mmp1b, mmp3 and c3 which possibly stimulate bone resorption by osteoclast, were commonly up-regulated, 4) the gene such as c1q and msr2 which were related with macrophage function, were commonly down-regulated, 5) the genes which possibly stimulate osteoblast differentiation and/or mineralization of extracellular matrix, were commonly down-regulated;slc8a1, admr, plod2, lox, fosb, 6) the genes which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were commonly up-regulated;s100a4, npr3, mme, 7) the genes such as calponin 1 and tgfbi which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were up-regulated by high extracelluar calcium but were down-regulated by VD3. These results suggest that in coculture condition, both high extracellular calcium and VD3 commonly induce osteoclastogenesis but suppress osteoblast differentiation/mineralization by regulating the expression of related genes.

Portal vein branch ligation has been implicated to stimulate the hypertrophy of the unaffected lobe of the liver, but it has been suggested that the degree of the hypertrophy of the cirrhotic liver would be less than that of the normal liver. So, we tried to induce biliary cirrhotic liver by ligation of the common bile duct for this experiment and to evaluate the difference of the effect of the portal vein ligation among the different experimental rat liver groups. For the experimental study, we used Sprague - Dawley rats which were classified into the two groups. Group A (N = 16): Rats with portal venous branch ligation only. Group B (N=16): Rats with portal venous branch ligation after biliary cirrhosis were made by common bile duct ligation. In order to induce biliary cirrhosis, we ligated the common bile duct ligation in 135 rats and exploratory laparotomy for biopsy was done 3 weeks later after common bile duct ligation and the incidence of biliary cirrhosis was about 40%(54/135). 16 rats with the biliary cirrhotic liver were chosen for further study and one of 5 portal branches was ligated and the rats were sacrificed at different time point(1st, 3rd, 5th, 8th week) after initiation of the experiment, and the livers were removed and examined to find out the gross and histologic changes of the livers. The same procedures were performed in 16 normal rats for control study. In the Group A, the severe inflammatory changes and multiple necrotic foci were shown in the ligated lobe from the 3rd week, and firm nodularity was palpated but hypertrophic changes were not noticed in the unaffected lobe. In the group B, ligated lobe showed the same findings with the group A, but unaffected lobe did not reveal any specific findings. In our experiment, we could induce biliary cirrhosis after common bile duct ligation but we could not examine any hypertrophic changes in the both groups-normal and cirrhotic livers - after portal vein branch ligation. This might suggest that only small portion of necrosis - less than 20% - can not induce compensatory hypertrophy in the unaffected lobe.

Impaction is the cessation of eruption process caused by physical obstacles on the eruption pathway, abnormal tooth position, or lack or space. It often occurs in association with supernumerary teeth, odontogenic tumor, or cystic lesions, and ameloblastic fibroma is one of the odontogenic tumors that can cause impaction of teeth. In many cases, ameloblastic fibroma occurs in association with one or more unerupted teeth. The proper management of ameloblastic fibroma is determined between conservative resection or more aggressive block resection, based size and morphologic features of the lesion and age of the patient. This is a case of a 8 year and 6 month old boy whose lower left permanent molar showed eruption disturbance. The impacted tooth was successfully repositioned favorably through surgical exposure and orthodontic traction using a modified halterman appliance. Long term follow-up, longer than 10 years, is planned considering relatively high recurrence rate and possibility of malignant transformation of ameloblastic fibroma, which cause impaction of the lower left permanent molar in this case. 매복이란 맹출로 상에 물리적 장애물이 있거나, 치아의 비정상적 위치, 또는 공간 부족 등으로 인해 맹출이 정지되는 경우이다. 이는 과잉치, 치성 종양, 또는 낭성 병소의 존재와 연관되어 나타나기도 하는데, 법랑모세포섬유종은 이러한 매복을 일으킬 수 있는 치성 종양의 한 종류이다. 법랑모세포섬유종은 많은 경우 미맹출 치아나 매복치와 연관되어 나타나며, 병소의 크기 및 양상, 그리고 환자의 연령을 고려하여 보존적 절제술(conservative resection) 또는 완전 절제술(block resection)을 시행한다. 본 증례는 하악 좌측 제1대구치의 맹출 장애를 주소로 내원한 환아에서 외과적 노출술 및 변형된 halterman 장치를 사용한 교정적 견인을 통하여 양호한 결과를 얻었기에 보고하는 바이다. 매복의 원인이었던 법랑모세포섬유종의 비교적 높은 재발률 및 악성 전환 가능성을 고려하여 추후 장기적인 추적검사가 필요할 것으로 사료된다.
