Cranocsynostosis is the term that designates premature fusion of one or more sutures in either the cranial vault or cranial base. Especially scaphocephaly, brachycephaly and trigonocephaly are included in simple symmetric craniosynostosis. In simple symmetric craniosynostosis, the functional deformity is rare, but deformity in external appearance is always a serious problem. The purpose of forehead reshaping in simple symmetric craniosynostosis is recovery of normal cerebral growth and improvement of cranial cosmetic problem by restoration of normal calvarial anatomic structure. Various surgical methods have Bbeen developed in an effort to correct craniosynostosis. Cranial vault remodeling with or without supraorbital band advancement is a widely accpeted method of correcting simple symmetric craniosynostosis. However, the standardized surgical method has not yet been estabilished in reshaping the forehead during cranial vault remodeling of simple symmetric craniosynostosis. The authors developed a new osteotomy method, the bull's osteotomy, which is a limited osteotomy for cranial vault remodeling. It produces posterior tilting of a prominant forehead as well as increased biparietotemporal distance for effective forehead reshaping. We applied this techriaue in 8 scaphocephaly and 2 brachycephaly patients under 5 years of age who have not yet reached bony consolidation. All patinets obtained satisfactory results with properly corrected deformity and no relapse was observed during the follow-up period. This new osteotomy method is simple and effective and a consistant surgical outcome is expected. particularly the contour of the forehead on the frontotemporal area is corrected to have a smooth and natural curvature. Based on our experience using bull's osteotomy, we offer this new surgical technique for managing simple symmetric cranoisynostosis patients.

PURPOSE: We determined the toxic and morphologic effects of the anti-proliferative drugs, mitomycin-C (MMC), 5-fluorouracil (5-FU) and genistein on rabbit corneal endothelium. METHODS: After intramuscular anesthesia, each drug of different concentrations (MMC at 0.05, 0.1, and 0.2 mg/ml; 5-FU at 5, 10, and 50 mg/ml; and genistein at 0.013, 0.027, and 0.054 mg/ml) was perfused into the anterior chamber of 54 white rabbits (108 eyes). The same amount of balanced salt solution was perfused into control eyes. The corneal thickness was measured before perfusion and 15 min, 30 min, 45 min, 1 h, and 24 h after perfusion. Corneal samples were prepared at 24 h after perfusion to determine the changes in corneal thickness and to observe morphologic changes of corneal endothelium under scanning electron microscope (SEM). RESULTS: A significant increase in corneal thickness was observed. Destruction of corneal endothelial cell structure was seen under scanning electron microscope at 24 h after perfusion with MMC at 0.2 mg/ml for 1, 3, and 5 min, and at 0.1 mg/ml for 5 min; and 5-FU at 50 mg/ml for 5 min into the anterior chamber. However, no significant difference was seen in corneal thickness or in corneal endothelial morphology at 24 h after perfusion with genistein. CONCLUSIONS: To avoid morphologic changes of the cornea, we recommend the anterior chamber perfusion of MMC at 0.1 mg/ml between 1 and 2 min, 5-FU at 10 mg/ml between 3 and 5 min, and genistein at 0.027 mg/ml for 5 min. Genistein at low concentrations showed no morphologic change in the cornea, suggesting the possible clinical use with safety.

Obesity is caused by interactions of energy consumption, amount of food intake, physical activity and etc, and these elements are influenced by genetic factors. Obesity related genes which have been known by now are over 200. One of these is Kir6.2 which forms the pore region of K(ATP) channel, and genetic variation of which may result in altered beta-cell electrical activity, insulin secretion, glucose homeostasis, and increased susceptibility to type 2 diabetes. Therefore, the purpose of this study was to examine the relationship between Kir6.2 E23K polymorphism and fat distribution or metabolic profiles in Korean. A total of 164 patients who visited Dongsan Medical Center Obesity Clinic from February 2004 to December 2005, were enrolled in this study. Screening for Kir6.2 polymorphism carried out by PCR-RFLP analyses. We divided this group into three groups E/E, E/K, K/K. Serum lipid and blood glucose were measured by autoanalyzer. Visceral fat amount and subcutaneous fat by abdominal CT, total fat mass by DEXA were measured. The subjects of E/E, E/K, K/K genotypes were 24, 79, and 61, respectively. The results of ANOVA analysis was that subjects with the K/K genotypes had more visceral fat amount (P<0.05) and higher total cholesterol levels (P<0.05) than E/E subjects group. Visceral fat amount and serum total cholesterol were significantly different according to Kir6.2 E23K polymorphism. Therefore, Kir6.2 polymorphism may act on fat distribution in Koreans.

BACKGROUND: To obtain reference values for the ambulatory blood pressure, 30 normotensive Korean young males, aged 22-28 years(mean age: 25 years) were investigated. METHODS: The ambulatory blood pressure was recorded with SpaceLabs Model 90207 monitor over 24 hours at 20 minutes intervals during day-time(6 am-10pm) and at 30 minutes intervals during night-time (10 pm-6 am). RESULTS: The ambulatory blood pressure of the 30 subjects averaged 119/74mmHg over 24 hours, 122/78 mmHg during day-time and 112/68 mmHg during night-time. The upper limit of normal ambulatory blood pressure was suggested as the value of mean+/-2SD which revealed 131/84mmHg for 24 hours, 134/90 mmHg for day-time and 126/80 mmHg for night-time. CONCLUSION: Reference values for the ambulatory blood pressure, in normotensive Korean young men, were obtained by SpaceLab model 90207 monitor.
