Our hospital have started laparoscopic cholecystectomy in 1991, and after then many surgeons have been trained in the era of laparoscopic and minimally invasive surgery. Since then numerous procedures have been applied for a laparoscopic surgery, and many patients have been benefited as a result. We have performed the first automated surgery in Korea using Automated Endoscopic System for Optimal Positioning (AESOP) in June, 1996. With the help of Inbae Yoon’s(a 1961 graduate of our medical school) inspiration and donation, our hospital has started “IB Yoon Multi-Specialty Endoscopic Research & Training Center” in 1998. As we started the robotic surgery we have change the name to “Severance Robotic and Minimally Invasive Surgery Center” in March 2005. These infrastructures enables us the expansion of laparoscopic surgery and inspires many surgeons to understand principles and equipments of laparoscopic and robotic surgery. We performed the first robotic surgery using da Vinci system in July, 2005. During 5 and half years after introducing the da Vinci surgical system in 2005 we have performed more than 10000 cases of robotic surgery successfully. With collaboration between medicine and robotic engineering company, we are developing our own version of Korean robotic system. In conventional laparoscopic surgery, limited motion of laparoscopic instruments, 2-D surgical field, and unstable surgical view resulted from unnecessary movement of laparoscope (shaking surgical field) by assist surgeons, magnifying tremor of laparoscopic instrument, and unexpected movement of laparoscopic instrument by another assist-surgeon can accidentally produce inappropriate environment for safe laparoscopic surgery. To the contrary, stable 3-D surgical field provided by robot surgical system, wrist like movement of instrument, stationary holding of fourth arm movement (to replace the role of assistant surgeon in laparoscopic surgery) seems to produce very appropriate surgical environment for safe laparoscopic HBP surgery. Therefore, robot is thought to be very appropriate for function-preserving minimal invasive HBP surgery.

OBJECTIVE: The purpose of this study was to investigate the changes in dentofacial morphology of non-orthodontically treated female patients with TMJ disk displacement. METHODS: The sample consisted of 25 Korean female patients with bilateral TMJ disk displacement who visited the Department of Orthodontics, Seoul National University Dental Hospital from 1996 to 2006. Disk displacements were diagnosed using the magnetic resonance imaging (MRI) of both TMJs. Baseline (T1) and follow-up (T2) lateral cephalograms were analyzed. The mean age of samples at T1 was 18.1 +/- 3.5 years (range 14.2 - 25.8 years) and at T2, 21.1 +/- 3.5 years (range 16.2 - 28.0 years). The mean observation period was 3.0 +/- 1.9 years. Descriptive statistics for each variable were calculated at baseline (T1) and follow-up (T2) stages, and during the observation period (T2-T1). RESULTS: Skeletal changes were found in 64% of the non-orthodontically treated female patients with TMJ disk displacement during the observation period. The L1 to Mandibular plane distance (mm) increased significantly by 0.8 mm (p < 0.01). But there were no significant differences in the other dental relationship variables (overjet, overbite, U1 to palatal plane) during the observation period. Most patients with skeletal changes showed a backward rotation of the mandible. The ratio of the rotation was a decrease of SNB by 0.43degrees for every 1degrees increase of FMA (Spearman rho = -0.660, p < 0.01). A few patients showed a distal shift of the mandible without rotation or significant changes in the vertical dimension. CONCLUSIONS: During observation periods without orthodontic treatment, non-growing patients with TMJ disk displacement showed dentoskeletal changes, mainly backward rotation of the mandible.

The one event on signaling mechanism is the cleavage by adenyl cyclase of ATP into second messenger, cyclic AMP. The other transfer system of inositol metabolism, it is widely recognized that hydrolysis of the minor membrane lipid phosphoinositide bisphosphate (PIP₂) initiated by occupation of certain receptors and catalyzed by phospholipase C, lead to toe generation of the two intracellular messengers, inositol triphosphate (IP₃) and diacylglycerol (DG). IP₃ is converted to inositol tetrakisphosphate (IP₄) by IP₃ kinase. In the present study, it is that purification of calmodulin is used by phenyl-Sepharose CL-4B chromatography, it's molecular weigh, 17,000 in SDS-polyacrylamide gel electrophoresis. In order to observe the affinity between calmodulin (CaM)-Affigel 15 and IP₃ kinase, and isolated IP₃ kinase, was applied in CaM-Affigel with Ca²⁺ equilibrium buffer and EGTA equilibrium buffer. We compared with binding and elution effect of IP₃ kinase in several condition of buffer. In affinity of binding, Ca²⁺ equilibrium buffer was in the most proper condition, and elution, CaM/Ca²⁺buffer (CE 1 10.36, CE2 12.76pM/min/mg of protein) was effected much more than EGTA buffer (E2 1.48, E 2.43pM/min/mg of protein), but CaM/Ca²⁺stimulate the activity of IP₃ kinase. And then, several detergents such as sodium deoxycholate, tween 20, cholic acid, polyethylene glycol, chaps were applied. The 0.2% chaps buffer (E2 23.19, E3 8.05pnM/min/mg of protein) was the most effective in elution of IP3 kinase.

BACKGROUND: The proportion of patients with subacute cutaneous lupus erythematosus(SCLE) is considered to be 10% among the total LE population in western countries. The morphology of LE-specific skin lesions in SCLE : appear as papulosquamous erythema or annular erythema developing mostly on the exposed areas. Among Korean patients with LE the prevalence and the pattern of cutaneous eruption of SCLE may be different from those patients of western countries. OBJECTIVE: To obtain the prevalence and the morphological characteristics of cutaneous lesions in Korean patients with SCI E v;ere the main objectives. METHODS: With 7 cases of SCLE, clinical dermatologic examinations for the character, the distribution, and the clinical course of those cutaneous lesions, and for the extent of systemic symptoms and LE-related laboratory abnormalities in each patient were performed. Results/Coeclusion. The prevalence of SCLE among Korean patients with LE or latent LE was much lower than those seen in Caucasians. The pattern of cutaneous lesions were papular/ papulosquamous erythemas with no (or rare) cases of annular erytherna among those patients diagnosed as SCLE. ~Other cl~inica! features were similar to Caucasian patients. It seems that there are some racial differences in the cutaneous manifestat.ions of LE, which may be relevant to the dissimilarities in immunogenetic backgrounds between different racial groups.

A series of 250 patients with filariasis due to periodic type of Brugia malayi was selected for the mass treatment with diethylcarbamazine from two areas in Cheju-Do. Two types of dosage schedules have been employed: the one was the conventional dosage schedule (uninterrupted dose of 6 mg/kg once daily 6 times repeated with an interval of one or two month totaling 72 mg/kg), and the other was the low dosage schedule (uninterrupted dose of 0.5, 1, 2, 4, 6 mg/kg body weight given once a day with an additional 6 mg/kg once daily totaling the maximum 37.5 mg/kg). The relative effectiveness of those two schedules was evaluated under the basis of the effects on microfilaria counts and the results of analysis of side-reactions observed. The results obtained in this experiment are summarized as it follows. In the conventional dosage treatment, 118 out of 141 microfilaria positives treated (83.7%) became negative and microfilaria reduction rate was about 99%. However, in the low dosage treatment, 35 out of 43 positives treated (85.4%) became negative and reduction rate of microfilaria, 99.5% in average. Total dose and duration of treatment were 72 mg/kg and about 60 days in the former schedule but it were maximum 37.5 mg/kg and 10 days in the latter. The recurrence of filariasis after treatment in both conventional and low dosage was negligible. Comparative analyses regarding the resulting side-reactions between the two schedules were made on their frequency, severity, onset and duration and relationship with microfilaria density. The febrile reaction was most frequently observed in 80.5% in the conventional, 43.9% in the low dosage schedule. The main side-reactions usually appeared within 6 to 10 hours and lasted 48 to 72 hours in the former threament, however they occurred in 7 to 8 hours and lasted 24 to 43 hours in the latter dosage schedule. It is assumed that the side-reactions are not directly related with the microfilaria count. However, the febrile reaction seems to be correlated with microfilaria density if it is above a certain limit. The presence of adult worm in a lymphnode involved with local reaction was ascertained from the biopsy specimens performed and local reactions such as lymphangitis and lymphadenitis after drug administrations were assessed from clinical and pathological point of view. It was conclusively indicated that the chemotherapeutic response to low dosage schedule within shorter length of treatment was equal to that of larger doses in long term medication from the point of the reduction in microfilaria, and particularly the resulting side-reactions were also reduced in the low dosage schedule.
