The changes in the size of human oviduct and ovary after immersion in formalin (4%, 10%) were investigated. The results were as follows : 1. After fixation, the length of oviduct was significantly reduced to 93%, but the cross sectional area of oviduct was significantly increased. The length of oviduct showed no significant difference between 4% and 10% formalin. The length of ovarian ligament was also significantly reduced to 84% after fixation. 2. After fixation, the volume of oviduct was increased significantly and showed a difference between the two fixatives. The volume of oviduct in 4% formalin has increased to 107%, as compared to 103% increase in 10% formalin. 3. After fixation, the volume of ovary was increased significantly and showed a difference between the two fixatives. The volume of ovary in 4% formalin has increased to 109%, as compared to 103% increase in 10% formalin.

Background: Fluvastatin is the first entirely synthetic 3-hydroxy-3-methylglutaryl-coenzyme A(HMG-CoA) reductase inhibitor. Clinical data indicate that this agent exhibits the proven efficacy of its class and also has some theoretical advantages in safety for long-term use because of its unique pharmacololgic property consistent with hepatoselectivity(i.e., low systemic exposure). This study is to evaluate efficacy and safety of fluvastatin in hypercholesterolemic patients in Korea. Methods: An open clinical trial with fluvastatin was conducted in 31 subjects who continued to have high blood cholesterol levels of 6.21 mmol/L(240 mg/dl) or greater after 1 month of lipid-lowering diet plus single blind placebo period. Fluvastatin was administered for 8 weeks with the initial dose of 20 mg per day and if serum cholesterol levels did not fall below 5.20 mmol/L(200 mg/dl) after 4 weeks the dose was increased to 40 mg per day for the second 4 weeks. On each visit every 4 weeks they underwent interview and laboratory tests about side effects and tolerability. Results: The mean % changes in plasma total cholesterol and LDL-cholesterol from baseline were

PURPOSE: To evaluate CT findings of internal hernia. MATERIALS AND METHODS: Three patients with internal hernia had abdominal CT scans and two of them had small bowel follow through examinations. The CT features of two patients with retroanastomotic and one patient with left paraduodenal hernia were evaluated and correlated with small bowel follow through examinations, and surgical findings. Two patients with retroanastomotic hernia had a history of subtotal gastrectomy with antecolic gastrojejunostomy. The diagnosis of internal hernia was made on the basis of surgical find ings in two patients of retroanastomotic hernia, and characteristic barium study findings in one patient of left paraduodenal hernia. RESULTS: The small bowel follow through examination showed small bowel loops gathered in a circumscribed mass in the left mid abdomen, and delay in passage through these loops. In case of left paraduodenal hernia, abrupt narrowing of the distal duodenum could be identified. The characteristic CT findings of all three patients were whorling of the mesentery and mesenteric vessels in the left mid-abdomen. In the patient with left paraduodenal hernia, after resolution of the gastrointestinal symptoms, a follow-up CT scan showed spontaneous disappearance of whorling of the mesentery and mesenteric vessels suggesting spontaneous resolution of the hernia. In the other two cases, upon exploration of the abdomen, dilatation of afferent duodenum caused by adhesion between ligament of Treitz and adjacent bowel walls, and retro- anastomotic herniation of the efferent loops were found. CONCLUSION: The usual diagnosis of internal hernia is based on the appearance of the small bowel follow through examination. However, we consider that the whorling appearance(we call it whorling sign) of the mesentery and mesenteric vessels on CT scan is also suggestive of internal hernia in patients under clinical suspicion.

A Statistical observations were done on 587 pediatric patients who were diagnosed as having congenital heart disease by cardiac catheterization angiography and operation at Dong San Hospital Keimyung University, during the period of January 1982 to june 1987. The results were as follows 1) Out of 587 patients, 317 cases were male and 276 cases were female. There were female preponderance in atrial septal defect and patent ductus arteriosus, whille in male tetralogy of Fallot, pulmonary stenosis, and ventricular septal defect. 2) The incidence of congenital heart disease were as folliws;ventricular septal defect 35.7% tetralogy of Fallot 17.5%, patient ductus arteriousus 13.9%, arterial septal defect 7.5% and pulmonary stenosis 2.9%. 3) Most of the patients were visited hospital for the first time between the age of 2 and 10 years. 4) Assosiated anomalies of major congenital heart disease were as follows:the most commonly associated anomaly in ventricular septal defect were pulmonary stenosis and patent ductus arteriosus. Pulmonary stenosis was frequently associated with atrial septal defect. Right sided aortic arch and pentalogy were assosiated with tetralogy of Fallot. The mitral regurgitation was associated with patent ductus arteriosus mostly. 5) The overall surgical mortality was 6.8%. The mortality was high in tetralogy of Fallot(16.1%), transposition of great vessels(28.5%).

The Graf stabilization has been introduced in treating lumbar spinal disorder associated with posterior instability. This study reviewed some problems of the Graf instrumentation as a soft stabilizer. The purpose of this study is to analyse the problems of the soft stabilization in spinal instability. We reviewed 145 cases which were operative treatment using the Graf instrument for lumbar spinal disorder associated with posterior instability at our department from May, 1991 to Dec, 1995. The mean follow up periods was 29 months ranging from 24 months to 6 years 8 months. Of the 145 cases, 22 cases were showed the problem. The diagnostic method were simple x-ray, flexion-extension lateral stress view and CT scan. Results were as follows : Adjacent segmental instability was 10 cases(6.9%), disc space narrowing was 8 cases(5.5%), screw loosening was 3 cases(2.1%) and breakage of the Graf band was 1 case(0.6%). The problems of the soft stabilization were adjacent segmental instability, disc space narrowing, screw loosening, and breakage of the Graf band. But the rate of adjacent segmental instability and disc space narrowing was lower than other lumbar spinal instrumentation.

BACKGROUND: Solar ultraviolet (UV) radiation induces sunburn, immune suppression, and various pigmentary disorders. Sunscreens are widely used to protect those untoward effects by UV but there are reports of phototoxicity or stability problems of sunscreens after exposure to UV. OBJECTIVE: We tried to compare sunscreens with different photostability in terms of their protection against various biologic responses like sunburn, immune suppression or pigmentation. METHODS: Three different sunscreens with SPF around 30 were used; Sunscreen-A (Sc-A) was photochemically inert, sunscreen-B (Sc-B) showed intermediate level of photostability, and sunscreen-C (Sc-C) was the least stable. To observe their in vivo effects, we measured sunscreen-protection against sunburn by back-skin swelling and sunburn cell formation, against immune suppression measured by depletion of Langerhans cells, local and systemic suppression of contact hypersensitivity (CHS), and against pigmentation by irradiation with mixed light source with UVA and UVB lamps that mimic solar UV spectrum. RESULTS: Back skin swellings by 5 kJ/m2 of UVB were protected well by sunscreens, but protection of Sc-C against 50 kJ/m2 of UVB was worse than Sc-A or Sc-B. Sunburn cells were increased significantly in mice irradiated with 5 kJ/m2 of UVB and it was protected by sunscreens, and the effect of photostability was minimal. Depletion of epidermal Langerhans cells by 5 kJ/m2 of UVB was protected completely by sunscreens. Local suppression of CHS by 5 kJ/m2 of UVB was protected by sunscreens, and Sc-A had better protection. But, in the experiment with 50 kJ/m2 of UVB, the protective efficacy was reversed; Sc-A showed worse protection. Systemic suppression of CHS by 10 kJ/m2 of UVB was protected well by sunscreens, and Sc-A had better protection and Sc-C had worse protection. In the experiment irradiated with 100 kJ/m2 of UVB, the protection of sunscreens was decreased, and Sc-B showed better protection, whereas Sc-C showed worse protection. In UV-induced pigmentation, all three sunscreens showed significant protection both by L* value and individual topographic angle (ITA) with the best protection by Sc-A and the worst protection by Sc-B. CONCLUSION: These data showed sunscreens can protect various in vivo responses and photostability of sunscreens played important roles particularly in the back-skin swelling and systemic suppression of CHS by high dose of UVB.
