The authors studied the formation of giant mitochondria in liver cell. The Sprague Dawley rats were sacrificed following intervals; 5, 10, 20, 30, and 60 minutes after intraperitoneal injection of hydrazine in the amount of 200 microliter/kg. And the extracted liver tissues were examined with light and electron microscopes. The results obtained were summarized as follow; Light microscopically, there is little difference between control and experimental groups. Electron microscopically, elongated, bizzare shaped mitochondria are appears 5 minutes after hydrazine injection. Those show attenuated portion, Y, U, or C shaped feature suggesting fusion or budding mitochondria. The number of giant mitochondria is decreased after 10 minutes group and rarely present in 60 minutes group. The results suggest in this experiment that the formation of giant mitochondria is kind of reversible change and it is different from the mitochondrial swelling of cellular injury. Intermitochondrial fusion and mitochondrial budding may be related with the formation of giant mitochondria.

It is the most important to select optimal culture conditions to promote safe embryo growth in the technique of human in vitro fertilization and embryo transfer. It has been shown that the addition of biologic fluids, such as blood serum, of various origins, improved fertilization and early cleavage rates in numerous species. The purpose- of this study is to attempt to measure developmental potential of mouse eggs fertilized and cleaved in Ham's F10 culture medium containing a chelating agent, EDTA and fetal cord serum. hi this study, we selected 40 female mice and 20 male mice, and investigated optimal serum concentration' for mouse embryo growth. Two cell stage mouse embryos were cultured in Ham's F-10 medium, Ham's F-10 medium with various concentrations of EDTA, or Ham's F-10 medium with EDTA and 10% human cord serum. Developmental ratios to morula in Ham's F-10 medium containing various concentrations of EDTA and/or 10% fetal cord serum were significantly higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to blastocyst in Ham's F-10 containing 10% fetal cord serum and 5011M or 100pM EDTA were significanldy higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to morula in Ham's F-10 containing 10% fetal cord serum and 100,uM EDTA were significanitly higher than in Ham's F-10 with 10% fetal cord serum used commonly in many human IVF centers(p<0.05). Developmental ratio to blastocyst in Ham's F-10 containing 10% fetal cord serum and 100pM EDTA was significanity higher than in Ham's F-10 with 200pM EDTA(p<0.05).

BACKGROUND: Lupus erythematosus panniculitis (LEP), (or lupus erythematosus profundus), is an unusual variant of lupus erythematosus which primarily affects subcutaneous fat. LEP may occur with or without other manifestations of cutaneous or systemic lupus erythematosus. Only a few studies on the clinical and histopathologic manifestation of LEP have been conducted in Korea. OBJECTIVE: The purpose of this study was to investigate clinical, laboratory, and histopathologic features of LEP in Korean patients. METHOD: A total of 30 patients confirmed as having LEP at the Chungbuk National University Hospital between 1 July 1994 and 31 June 2004 were included in this study. The medical records and histopathologic findings were reviewed. RESULTS AND CONCLUSION: 1. LEP occurred predominantly in females, with the female to male ratio being 4: 1. The mean age at diagnosis was 38.5 years. 2. The most common clinical features were nodules or plaques, and 60% of the patients had pain or tenderness. Skin lesions affected the proximal arm area, face, trunk, scalp, and buttocks. In 26% of cases, LEP was associated with discoid lupus erythematosus (DLE), and 13% had evidence of mild systemic lupus erythematosus (SLE). The antinuclear antibody (ANA) was positive in 30% of cases. 3. The main histopathologic characteristics of LEP were predominant lymphocytic lobular panniculitis, hyaline necrosis, mucin deposit, and lymphoid aggregates. 4. Treatments included antimalarial drugs, systemic corticosteroids, intralesional corticosteroids, or topical potent corticosteroids under occlusion. They produced some improvement in most cases, however LEP exhibited a chronic nature with a high relapse rate.

Endovascular stenting is accepted as an effective treatment for patients with Budd-Chiari syndrome (BCS). We herein present a case of successful endovascular treatment. A 46-year-old woman, who was followed up for 10 years after a diagnosis of BCS, showed progression progressive of liver cirrhosis and deterioration deteriorated of liver function. Three main hepatic veins were thrombosed with complete occlusion of the suprahepatic of the inferior vena cava (IVC); thus, hepatic venous blood flow was draining into the inferior right hepatic veins through the intrahepatic collaterals and passed passing through the subcutaneous venous collaterals. She underwent endovascular stenting of the IVC for palliation. A septoplasty needle was passed through the occluded IVC through into the internal jugular vein access and then to access the femoral vein using a snare wire. Severe elastic recoiling was observed after balloon dilatation; thus, a 28x80 mm stenting was done inserted across the occlusion, and repeat double ballooning was performed. The final venogram shows showed restored IVC inflow. The patient began to lose body weight 1 day after stenting, and edema disappeared within 1 week. She is was doing well at the 6 month follow-up visit with nearly normal liver function and marked resolution of cutaneous venous engorgement. In conclusion, endovascular stenting appeared to be an effective treatment to alleviate portal pressure and to prevent BCS-associated complications; thus, endovascular stenting should be considered before marked hepatic vein stenosis or complete occlusion occurs in patients with BCS.

Statement of problem: Many factors influence shade determination in clinical practice and shade matching is highly affected by the viewing conditions. Purpose: This study investigated the differences in shade perception among distinct groups of dental personnel (10 prosthodontists, 10 general practitioners, 10 last-year dental students and 10 dental technicians). Material and method: Four groups of dental personnel were investigated. They were tested to eliminate color blindness. To compare shade selection ability, they were asked to match four test tabs of shades A3, B2, C2 and D4 (VITAPAN. Classical shade guide. The identification codes of the shade tabs were masked to prevent shade memory.) against another full set of VITAPAN. Classical shade guide under similar lighting conditions. Shade selections were randomly repeated five times every week and then the repeatability between dental personnel was evaluated. To compare value perception ability, they were asked to arrange randomly selected five test tabs (B1, A2, D2, C3, A4) in descending order from the brightest to the darkest. To compare hue determination ability, they were asked to divide selected eight test tabs (A2, A3, B2, B3, C2, C3, D2, D3) into four groups by manufacturer as follows: Group A-Reddish brown, Group B-Reddish yellow, Group C-Grey, Group D-Reddish grey. Results and conclusion: The obtained results were as follows: 1. For the value perception ability and hue determination ability, there was no significant difference among 4 groups: prosthodontists, general practitioners, dental students, dental technicians(P>.05). 2. For shade selection ability, the prosthodontists and dental technicians were significantly higher than dental students(P<.05). 3. The repeatability of selected shade in the dental technicians was significantly higher than that of general practitioners and dental students(P<.05). 4. The prosthodontists and dental technicians had significantly higher selection ability than dental students for shade B2(P<.05).
