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.

The solid and hematologic cancer are occasionally accompanied by peripheral blood eosinophilia and suggest tumor necrosis or wide dissemination, but the mechanisms underlying this curious relationship remain obscure. The association of this eosinophilic leukemoid reaction with carcinoma seems to occur must frequently with bronchogenic carcinoma. Several mechanisms for this association were considered: eosinophil chemotactic factor, eosinophil mediated by T-lymphocyte, and eosinopoietic hormone. We are here reporting a case of bronchoalveolar cell carcinoma of lung associated with peripheral eosinophilia in a 60-year-old male patient.

Midtrimester genetic amniocentesis has been a gold standard for prenatal diagnosis in antenatal care since last 25 years. After the triple serum marker test was introduced as a prenatal screening method for Down syndrome, the frequency of genetic amniocentesis was increased. OBJECTIVE: To determine the complication, risk of amniocentesis and detection rate of chromosomal abnormality. MATERIAL AND METHODS: A retrospective clinical analysis of 1,064 midtrimester genetic amnicentesis in IL Sin Christian Hospital antenatal clinic from Jan 1995 to Dec 1997. Chi square test was used for the statistical analysis and p value < 0.05 was considered significant. RESULTS: Amnicentesis were significantly increased in the age of 35-39 yrs and 40yrs over. And also the incidence of chromosomal abnormality was higher than younger age group. The indications of amnicentesis were screen positive of triple marker test(43%), advanced maternal age(20.8%), abnormal beta-hCG level, past history of chromosome abnormality or malformed baby and abnormal alpha-FP level in order. Total number of chromosomal abnormalities was 30 and the incidence of chromosomal abnormalities was 2.8%(30/1,064). The complications were developed in 13 cases and fetal loss rate was 0.78%(9/1,064). CONCLUSION: The detection rate of chromosomal abnormality in midtrimester amnicentesis for prenatal diagnosis was high and relatively safe procedure but, we should be attention to more careful manipulation.

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.

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.
