Cryptotia is a rare congenital auricular deformity among Caucasians but more common in Asians. Various operative techniques have been described, such as skin graft, V-Y plasty, Z plasty, and islands skin flap. Among those techniques, V-Y plasty has many advantages and is indicated for severe cases. However, several problems remain when this method is adopted, such as conspicuous scars and lowered hairline. To overcome these problems, the authors have developed a new technique, multiple V-Y advancement modification, which stitches the skin flaps together to a tight, discrete central focal point. This technique has the advantage of hiding scars behind the earlobe, providing enough skin for the deformed areas, minimizing the condition of the hairline being lowered and auriculocephalic sulcus depth.

Cerebrovascular disease and coronary heart disease are the first and the fourth common causes of death among adults in Korea. Reported risk factors of these diseases are mostly alike. But some risk factors of one of these diseases may prevent other diseases. Therefore, we tried to compare and discriminate the risk factors of these diseases. We recruited four case groups and four control groups among the inpatients who were admitted to Wonju Christian Hospital from March, 1994 to November, 1995. Four control groups were matched with each of four case groups by age and sex. The number of patients in each of four case and control groups were 106 and 168 for acute myocardial infarction(AMI), 84 and 133 for subarachnoid hemorrhage(SAH), 102 and 148 for intracerebral hemorrhage(ICH), and 91 and 182 for ischemic stroke(IS) respectively. Factors whose levels were significantly higher in AMI and IS than in responding control group (RCG) were education, economic status, and triglyceride. Factors whose levels were significantly lower in hemorrhagic stroke than in RCG were age of monarch, and prothrombin time. The factor whose level was higher in AMI than ill RCG was uric acid. The factor whose level was higher in AMI, ICH, and SAM than in RCG was blood sugar. Factors whose levels were significantly higher in all the case groups than in RCG were earlobe crease, Quetelet index, white blood cell count, hemoglobin, hematocrit, and total cholesterol. The list of risk factors were somewhat different among the four diseases, though none of the risk factors to the one disease except prothrombin time acted as a preventive factor to the other diseases. The percent of grouped cases correctly classified was higher in the discrimination of ischemic diseases(AMI and IS) from hemorrhagic diseases(SAM and ICH) than in the discrimination of cerebrovascular disease from AMI. The factors concerned in the discrimination of ischemic diseases from hemorrhagic diseases were prothrombin time, earlobe crease, gender, age, uric acid, education, albumin, hemoglobin, the history of taking steroid, total cholesterol, and hematocrit according to the selection order through forward selection.

Chronic oral aphthae, recurrent ulcer and uveitis are the three main festations of Behcet's disease(BD). The aetiopathogenesis of Behcet's disease is still obscure, but herpes simplex virus is one of the possible casual factors. Gamchosasim-tang (Gancaoxiexin-tang), Banhasasim-tang(Banxiaxiexin-tang) and Saenggangsasim-tang( Shengjiangxiexin-tang) are traditional medication in Oriental medicine, that has been used to treat inflammatory disease. Especially, Gamchosasim-tang used to treat Behcet's disease like symptoms. ICR mice were used for this study. The earlobe of the mice were scratched with a needle, then inoculation with 1.0×10/sup 6/ plaque forming units/㎖ of HSV type I. Virus inoculation was performed twice with 10 day interval, followed by 16 weeks of observation. Using the HSV-induced Behcet's disease mouse model, kinds of Sasim-tang were administered variously before and after inoculation. In order to. classify the symptomatic mice as having Behcet's disease like symptoms. We followed the revised Japanese classification with minor modifications. Ulceration of the mice were monitored. In addition, spleen cytokine expression were measured by polymerase chain reaction, ELISA. HSV DNA was detected in HSV inoculation mice. HSV-induced mice treated with kinds of Sasim-tang showed improvement in symptom. In RT-PCR results, IFN-γ was expressed for all groups, IL-2 was expressed for the treated groups, and IL-10 was also expressed. IL-4 was expressed nothing. In ELISA, IL-2 was increased for GSST 2, BSST 2, GSST 2, GSST3 and INF-γ was increased for GSST 2, BSST 2, SSST 2, SSST 3. This model suggest the possible role of immune response to viral infection in the development and activation of Behcet's disease.

The regimen of physical activity of the patient with coronary artery disease requires that he should not overshoot the prescribed heart rate based on his age, health and fuctional status of the heart during his exercise. The step input of work load, however, involves a great danger of overshooting. The purpose of this study was to desigil a system that makes it passible for a subject to check the overshooting. This system shows on tile H.R-meter, the amplified and filtered heart-rate signal of the subject received by the photosensor on his earlobe, puts it in the lead coinpensational circuit where it is conpared with the reference input signal(=the presfribed heart rate). The output of the lead compensational circuit works the aull meter. By means of this null meter, the subject knows whether he is overshooting the prescribed heart rate or not. He can continue the natl meter needle at the'Zero'position through the control of the speed of pedaling of the bicycle ergometer, An experimental test, made on eight men and four women in healthy condition, showed that 91. 7% of them vlaintained the stable heart rate and that the overshooting of the desired heart rate did not exceed $\pm$2BPM. According to the result of this experiment, since the heart rate feedback controller makes it possible for the subject to take the prescribed exercise based not on the work load but on the heart rate which incidentally is inexpensive, it can be made use of as the instrument for the regimen of pflysical activity by the patient with coronary artery disease.

The aim of surgery for all parotid masses is directed toward total removal of the tumor with adequate safe margins of adjacent normal tissue and preservation of the facial nerve whenever possible. Reconstructive procedures following parotidectomy for benign or low grade malignant lesions are most commonly necessary if soft tissue deficits appear at the angle of the mandible below the earlobe as a major cosmetic deformity. This is a report of Z4 cases with a diagnosis of parotid tumor who were treated using various surgical procedures at Department of Plastic and Reconstructive Surgery, Hanyang University Hospital over the period of 4 years from January, 1983 to December, 1986. Among 24 cases, 11 cases were reconstructed by Sternocleidomastoid muscle flap at the same time that extirpative surgery is outlined. The advantage of Sternocleidomastoid muscle flap is the coverage of the facial nerve, so adhesion between the facial nerve and skin was prevented. Absorption and loss of bulk was not found such as dermofat graft. It was a simple method. Neither donor site defect nor sternocleidomastoid muscle deformity was developed. Sternocleidomastoid muscle flap have been found satisfactory in maintaining filled-out soft tissue hollows with good result cosmetically and functionally.

In this study, the effects of verapamil on growth rate, apoptosis, production of transforming growth factor (TGF-${\beta}$) and fibronectin were evaluated in keloid and normal human dermal fibroblasts. Both fibroblasts were primarily cultured from earlobe keloids of three female patients and treated with various concentrations of verapamil. Cell toxicity was assessed by MTT assay, growth rate and apoptosis by FACS, and the production of TGF-${\beta}$ and fibronectin by ELISA and Western blot, respectively. In the $MTT_{50}$, the cell growth was more suppressed in keloid fibroblasts. In the $MTT_{90}$, cell growth was more stimulated in normal fibroblasts. No significant effect appeared on TGF-${\beta}$ expression but an increase in extracellular fibronectin secretion was found in keloid fibroblasts. Keloid fibroblasts responded to verapamil more sensitively, and the percentage of apoptosis was higher at the $MTT_{50}$l. In brief, verapamil had growth-inhibitory effect with inducing apoptosis at the $MTT_{50}$, but rather growth-stimulatory effect at the $MTT_{90}$. The biphasic effect of verapamil depending on the dose might explain one of the reasons of relapse after keloid treatment with verapamil. Clinical application with high concentration (2.5 mg/ml) is advised unless excessive dosage is used.
