Minimal cleft lip has been defined as a cleft which does not extend over the vermilion. Minimal cleft lip has no specific classification and few methods for its correction. Based on our operative experience with secondary cleft lipnose deformities, we have developed principles of operation for minimal cleft lip: minimal incision, nostril and alar reconstruction, philtrum reconstruction. alignment of cupid's bow, and vermilial notching correction. Nine patients of minimal cleft lip were operated on from March 1992 to June 1998 in our department. Each partients was evaluated for lip and nose deformities presurgically: the nasal tip, columella, ala, scar, cupid's bow, lip pout and lip length. Every patients required a different technique for repair. Satisfactory results were obtained by treating the cleft following the principles.

The dose-ralated dffects of intravenous infusion of thiopental and ketamine on the rat EEG were evaluated quantitatively by spectrum analysis of EEG recorded from the rat scalp. The anesthetics were infused into jugular vein at various rates ranging from 0 to 8ug/min/g body weight, and then bipolar EEG was recorded from the rat scalp and tis spectrum were calculated by powere wpectrum analysis. the density of each bands(delta 1-3.25, theta 3.5-7.75, alpha 8-12.15, beta 1.13-17.75, beta 2.18-20.75, and beta 3.21-31.75Hz) and total density were derived from the spectrums. In visual inspection of conventional EEG, low doses of thiopental increased the amplitudes of spinles. but higher doses decreased the amplitube gradually to electrical silence with increase of infusion rates. During infusion of higher doses of ketamine, two types of EEG were identified by the spectral patterns:The one was the cases in which increases of the power density over all frequency ranges were observed, and the other was those in which marked increases of density in specific frequency were observed. In thiopental infusion, the densities of all bands were increased to peak at 1~2ug/min/g and therafter were decreased with higher rates of infusion. In ketamine infusion, the densities were increased when the infusion rate was increased. These results suggest that, by the changing patterns of the band densities dervied from spectrum analysis of EEG, not only the effect on EEG of thiopental of tetamine can be quantified but also their differences of mechanisms of action on brain be reflected.

Frey's syndrome is a fairly common sequelae of surgery, trauma and inflammation of the parotid gland. Some patients with Frey's syndrome may be socially compromised by their gustatory sweating and flushing. In the past three decades, a variety of surgical and pharmacological methods have been unsuccessful in alleviating these symptoms. And since misdirection of auriculotemporal secretomotor nerve fibers has been found to play an important role in the development of the syndrome, a study was initiated to attempt mechnical interference with regenerating nerve fibers. Therefore, the recent trend in management of Frey's syndrome has been the use of prophylactic procedures performed at the time of parotidectomy to prevent its symptoms postoperatively. An additional benefit of this approach is prevention of the typical cheek contour deformity after parotidectomy We reviewed our experience with interposition of a vascularized temporoparietal fascial flap between the parotid bed and overlying skin immediately after complete superficial parotidectomies to prevent Frey's syndrome and hollow contour defects. The result of seven consecutive attempts revealed it to be an effective technique, achieving both goals in all patients with minimal morbidity.

BACKGROUND: The risk of hypertension increases as body weight is gained. In most studies, smoking has been considered as a confounder in association, but such association had not been analyzed accordingly to smoking status. The purpose of this cross-sectional study was to assess whether the relation between weight and the risk of hypertension varied according to smoking status. METHODS: The subjects were 1,813 male workers who had routine health examination from April to June in 1998. They were divided into current smokers and non smokers according to smoking status and categorized into three different weight groups; normal weight (BMI<23 kg/m2), overweight (23or=25 kg/m2). Hypertension was defined if systolic blood pressure was >140 mmHg, or diastolic blood pressure was >or=90 mmHg. The interaction between smoking status and BMI for prevalence of hypertension, and the prevalence odds ratios for hypertension among six groups categorized according to weight and smoking status, were analyzed by multiple logistic regression. RESULTS: The interaction between smoking status and BMI was significant (beta= 0.058, SE=0.025, P=0.021). The risk of hypertension was 1.55 times (95% C.I 0.76-3.15) higher among the non-smokers with overweight and 2.09 times (95% C.I 1.01-4.32) higher among the non-smokers with obesity compared to the non-smokers with normal weight after controlling for age, serum glucose, and total cholesterol. In contrast, weight was not associated with the risk of hypertension among smokers. CONCLUSION: The risk of hypertension rose as the weight of non-smokers increased. However, there was no association between the weight and the risk of hypertension among current smokers.

Various remedies have been developed for broad damage to soft tissue in limbs by traffic accidents and mechanical mishaps that have greatly increased in modern society. If the damaged part is trivial, it may be generally treated with local flap or skin graft. However, this has been limited by the ability to choose the flap available depending on the condition of the wounded part, so that, if it is rather large or severly inflamed, or if it occurred with a bone-fracture, it is inevitable to practice the free flap. In the past, the focus was on whether the free flap would survive or not. However, the function of donor the and recipient, as well as the problem of aesthetic appearance, gas become a matter of increqsing interest and concern as the survival rate of the flap has greatly improved due to the development of precise operations. In thes study, therefore, some complications were analyzed which may develop in a donor by a variety of free flaps. Preoperative plans, as well as intraoperative and postoperati-ve treatment were also studied to minimize the cause of complications. To investigate these questions, we undertook a clinical analysis of 91 followed patients from 1990 to 1997. There were 68 male and 23 female patients ranging in age from 6 to 67 years, with an average of 34.7 years. The length of follow-up ranged from 8 months to 6 years. The results of this study were as follows: Sufficient plans must be made on the donor before operation, single textures like muscle or fascia should be used if possible, and incision should be arranged along Langer`s line. Some measures to reduce wound tension should be pursued, and plans must be made to immobilize the site for an ample period after the operation. Some precautious should also be considered during the operation, such as avoiding traction surrounding nerves and vessels, preserving paratenon, practicing osteotomy with great care and properly stopping any bleeding. In addition, formation of a hematoma or seroma should be preventcd and the donor must be sutur-ed as soon as possible to reduce infection. With the application of the basic operational principles on the treatment of donors, the complications which might be caused by each free flap can be reduced, and furthermore, be protected against.

The central dopaminergic receptor is believed to suppress the cardiovascular system So it may be involved in the blood pressure regulation But, it's action is still controversial. Furthermore, the mechanisms involved in the central dopaminergic receptor-induced blood pressure regulation is unclear. So, present study was performed in order to clarify the effects of central dopaminergic receptor and to investigate the mechamisms involved in it. Lisuride a D2-receptor agonist, and clonidine, a alpha2-receptor agonist, were administered into lateral ventricle in rat and the changes of blood pressure were compared The results were as follows; 1. Intracerebroventricular administration of lisuride amd clonidine from 0.3 ug to 10 ug elicited dose related decrease of blood pressure and heart rate. The potencies were similar in both drugs. 2. Centrally administered sulpiride, a D2-antagonist, blocked only the lisuride-induced hypotension while the clonidine induced hypotension was blocked only by centrally adrninistered tolazoline, a alpha2-antagonist. Intravenous administration of both antagonists elicited no or minimal attenuabon of agonists effects. 3. After desipramine pretreatment, which increases the norepinephrine concentration lisuride elicited somewhat further decrease of blood pressure than normal, while clonidine administration caused rather increase in blood pressure. 4. After chemical sympathectomy by 6-hydroxydopamine, lisuride administration still elicited strong suppression of blood pressure. From thses above results, it is concluded that central dopaminergic receptor activation decrease the blood pressure. Suppression of the norepinephrine release at the sympathetic nerve terminal is not related with central dopaminergic receptor induced hypotension.

BACKGROUND: Influenza is a highly contagious respiratory disease. Influenza virus, which causes epidemics every winter season, has the high possibility of appearing with new virus types every year due to antigen variation. Therefore, we intended to analyze the data on the epidemiology of influenza that had been acquired by laboratory surveillance in Incheon during the 2003/2004 and 2004/ 2005 seasons and to apply the knowledge to the control and prevention of influenza in Korea. METHODS: Specimens were inoculated into Madin-Darby canine kidney (MDCK) cells and, when cytopathic effect (CPE) was seen, culture supernatants were tested by mutiplex RT-PCR for typing and subtyping of influenza viruses. RESULTS: The first virus of the season was isolated at week 47 (3rd week on November) in 2003 during 2003/2004 and at week 43 (4th week on October) in 2004 during 2004/2005, which was about 4 weeks earlier than in the 2003/2004 season. From 532 specimens cultured for influenza virus during the 2003/2004 season. 330 (62.0%) viruses were isolated: 161 (48.8%) A/H3N2, 1 (0.3%) A/H1N1, and 168 (50.9%) B. During 2004/2005 season, 457 specimens were tested and 278 (60.8 %) were positive for influenza virus: 232 (83.5%) A/H3N2, 5 (1.8%) A/H1N1, and 38 (13.7%) B. The incidence of influenza was the highest in the school-age children and young adults of 7 to 19 years age group in both seasons. CONCLUSION: Influenza virus was isolated at a high rate (more than 60%) by the laboratory influenza surveillance system in Incheon during the 2003/2004 and 2004/2005 seasons: the predominant strain was influenza A/H3N2 subtype.

BACKGROUND: The purpose of this study was to identify health practices that would be helpful in order to reduce the prevalence of correctable cardiovascular risk factors (CVR), i.e. hypertension, hypercholesterolemia, and hyperglycemia in male workers by examining the association between health practices and the prevalence of the three risk factors. METHODS: For 1,815 male workers at a car manufacturer who participated in the basic health examination, survey on socioeconomic status and seven healthy practices suchas not currenly smoking, moderate alcohol drinking, proper weight control, regular exercise, 7-8 hour sleep, eating breakfast regularly, and not eating between meals was done and the prevalence of hypertension, hypercholesterolemia, and hyperglycemia as obtained. x2 test, Fisher's exact test, and multiple logistic regression analyses were done for workers under 40 years old and workers 40 and over in two, separate groups by adjusting socioeconomic variables. RESULTS: The prevalence of hypertension and hypercholesterolemia was 1.84 times and 5.22 times, respectively, showing, higher in overweight younger workers than in those of normal weight. The prevalence of hypercholesterolemia was 2.02 times higher in younger smokers than in younger non-smokers. In contrast, the prevalence of hyperglycemia was 4.99 times higher in older smokers than in older non-smokers. The prevalence of hyperglycemia was 16.5 times higher in older workers with regular snacking habit than in those without such a habit. The prevalence of hypercholesterolemia was 7.47 times higher only in younger workers practicing healthy behaviors below 3 than in those practicing at least 6 healthy behaviors. CONCLUSION: Our study suggests that overweight and smoking habit among younger workers, and smoking habit among older workers sould be controlled in order to decrease the prevalence of hypertension, hypercholesterolemia, and hyperglycemia.

The reconstruction of soft tissue defects on the leg remains a difficult challenge for plastic surgeons. If the defect is large and complicated by bone or joint defects, and excellent result can be obtained with free tissue transfer. In cases with no bony problem, no severe osteomyelitis and small medium-sized defects local flap is more acceptable than free tissue transfer because of its simple onestage and reliable operation. Fasciocutaneous turnover flaps revolve around the lack of criteria for safely designing these random pattern flaps as well as the risk of donorsite problems. Vertically-based deep fascia turnover flaps nourished by the subfascial plexus within deep fascia were used successfully for reconstruction of the leg in 5 patients. A vertically-based deep fascia turnover flap consists of deep fascia of the leg and its subfascial and epifascial plexus. As musculofascial, septofascial and periosteofascial branches these contribute to a richly anastomosing vascular network within deep fascia. Unlike adipofascial turnover flaps, the transversely-oriented deep fascia turnover flap keeps its subcutaneous layer with its intact vascular plexus so that the overlying skin is adequately perfused, even in patients with sizable flaps or extremely thin skin. Between March 1998 and February 1999, five cases underwent this procedure to reconstruct soft tissue defect on the leg. The advantages of this method are fast, safelyelevated preservation of the superficial vascular plexus, thus preserving the shape of the leg minimizing donor site scar and hypertrophy.
