BACKGROUND AND OBJECTIVES: As previously reported, unstable angina is usually related to characteristic coronary artery lesion's morphology analyzed by coronary angiogram. This takes the form of an eccentrically placed convex stenosis with a narrow neck due to one or more overhanging edges or irregular, scalloped borders, or both. Although most studies were done for lesions with high degree stenosis(>50%), recent studies emphasized the role of vulnerability of plaque in acute coronary syndrome and even mild degree stenotic lesions may progress rapidly to evoke acute coronary syndrome. Therefore in this study, we analyzed the morphological characteristics of coronary artery lesions with mild degree stenosis as well as severe stenosis. MATERIALS AND METHODS: We conducted a retrospective study of 96 patients with angina pectoris (42 of stable patients and 54 of unstable patients) who underwent coronary angiography. Each lesions with 25% or greater diameter stenosis were categorized into simple and complex lesion(convex intraluminal obstruction with a narrow neck or irregular borders, diffuse irregularities, ulceration, thrombus). Calcification of coronary artery, extents of lesions were analyzed and stenosis grade and location were categorized by AHA classification. RESULTS: There were no significant differences between the stable angina and unstable angina in risk factors and vessel involvement, numbers of lesions, calcification and total obstruction. In morphologic analysis, complex lesions were more frequent in unstable angina than stable angina (49% vs 33%, p<0.05). The mean of percent diameter stenosis was not signigicantly different between two groups, but severe stenotic lesions with 90% or more stenosis were more frequent in unstable angina (34% vs 22%, p<0.05). Locations of involved vessels were similar between the angina groups. Complex lesions were distributed more frequent in RCA and simple lesions were more in LAD and LCX (p<0.05). CONCLUSIONS: The lesions with both complex morphology and severe degree stenosis are closely implicated in unstable angina.

Craniofacial clefts are rare among facial anomalies with an incidence of 1.5 to 5 per 100,000 births, and 1 per 100 cases of cleft lip and palate. The Tessier No. 7 clefts are unusual lesions that result from failure of the embryonic mandibular and maxillary processes to properly fuse and form the corners of the mouth. We experienced a case of Tessier No. 7 craniofacial cleft in a 1 day-old female patient who presented with a macrostomia and auricular malformation. The diagnosis was established by clinical and radiographic findings. A brief review of literature was made.

Ipratropium bromide (IP) is a new anticholinergic bronchodilator. To evaluate its effect on bronchial asthma which is still unknown in Korea, a double blind and randomized study was done on all patients of bronchial asthma who visit out-patients clinic of out department from June to September 197 and showed 75 to 100% of FEV1/FVC ratio on prebronchodilator spirometry (pre BD). The selected patients were given 2 puffs of Fenoterol (FE) or Ipratropium inhalator blindly and Spirometry. The repeated results are: 1. In both FE and IP groups, there was a significant bronchodilatory effect on 5 and 60 minutes after administration. 2. One 5 minutes, effect of FE was significantly greater than IP (FVC p<0.05, FEV1 p<0.01). 3. One 60 minutes, effect of IP was slightly less than FE but statistically non-significant. On the basis of above results, we concluded that onset of effect of IP is slower than FE, but its effect is significant and nearly comparable to FE.

Empyema thoracis following pneumonia, intra-abdominal pathology, trauma, and surgical procedure continues to be a source of major morbidity and mortality. Thirty seven adult and eleven pediatric patients with empyema thoracis were treated at the University of Yeungnam Medical Center from May 1983 to November 1986. Age distribution ranged from 6 months to 72 years and showed a double-peaked curve with the highest incidence between 36 and 65 years and below 15 years of age. There were male predominance in patients above 16 years of age. The most common predisposing factors was impaired consciousness due to either alcoholism or head injury. The causes of empyema were as follows: pneumonia 64.6%, ling abscess 6.4%, intraabdominal pathology 6.4%, and surgical procedure 6.4%. The cardinal symptoms were fever, cough, chest pain, dyspnea, sputum, weight loss, anorexia, and night sweat in orders. Culture of empyema fluid were positive in 50% of patients. The isolated organisms were Gram-negative bacilli 33.3%, staphylococcus aureus 25%, and streptococcus 25%. The patients received antibiotics in conjunction with various invasive procedures: chest tube drainage 77.1%, decortications 6.3%, and repeated thoracentesis 10.3%. There were 4 deaths, 1 child and 3 adults, with an overall mortality of 8.3%.

This study was aimed to explore the relationship between the type of family system and the self-concept of kidney-transplantation recipients. 190 recipients were sampled from 3 general hospitals in Seoul and Kunggi-area, KOREA. Family Cohesion and Adaptability Evaluation Scale III (Olson et al., 1985) of the Circumplex Model (Olson et al., 1983) and Self-concept Test (Jeong, Won Sik, 1968) were used to collect the data. The data collected was analyses by the t-Test and ANOVA. It was found that there were no differences on recipients' self-concepts by types of family systems. But there were differences in recipients' self-concepts by family cohesion and adaptability levels. That is, the higher level of cohesion and adaptability, the higher the recipients' self-concepts. The type of family system and recipients' self-concept are related. So the recipients and the family of recipients must be included in subjects of medical and nursing care.

Annular erythema associated with lupus erythematosus/ Sjogrens syndrome has recently been described in Orientals. We present a patient with recurrent annular erythema who partially demonstrated features of lupus erythematosus. A 32-year-old man was referred to us for recurrent annular erythema. Laboratory findings revealed mild leukopenia and the presence of antinuclear antibodies at a titer of 320 with a finely speckled pattern on Hep-2 substrates. Anti-Ro/La antibodies were also detected. A skin biopsy specimen revealed the findings of perivascular and periappendageal lymphocytic infiltration without prominent hydropic degeneration of the basal layer. Skin lesions subsided with hydroxychloroquine (400-200mg/day).
