Congenital adrenal hyperplasia, especially due to steroid-12-hydroxylase(P450c21) deficiency, is one of the most common autosomal recessive inborn errors at adrenal steroidogenesis in Korean. Molecular genetic analysis has demonstrated that there are two steroid 21-hydroxylase genes, CYP21A1P and CYP21A2. The CYP21A2 gene encodes P450c21, whereas the CYP21A1P gene is a pseudogene. Since there is 98 percent homology between the CYP21A1P and CYP21A2 gene in nucleotide sequences, it has hampered the characterization of molecular defects in the CYP21A2 gene.In this study, efforts have been made to selectively PCR amplify the CYP21A2 gene and test feasibility of DNA microextraction from Guthrie card for prospective use of molecular screening. This study was also aimed at investigating deletion mutations in P450c21 deficient patients, as well as allele frequencies and average heterozygosity of exon 1 A/C polymorphism in Korean newborns. Genomic DNAs were obtained from Guthrie cards of 50 Korean newborns by microextraction method and these DNAs were analyzed by PCR-allele specific oligonucleotide(ASO) hybridization. First part of the CYP21A2 gene has been successfully amplified and digested by restriction enzyme using Taq I or Kpn I, subsequently run on 1.5% agarose gel to confirm its specificity. The anterior 1141 bp PCR product was utilized to examine the frequency and average heterozygosity of exon 1 A/C polymorphism in 100 alleles by ASO dot blot hybridization. Amplified genomic DNAs from four P450c21 deficient patients out of three families were screened by PCR to see if any one has complete deletion of the CYP21A2 gene.The results were as follows;1) The average 1230ng of genomic DNA was obtained form single semi-circled Guthrie card of 1/2 inch diameter by microextraction method, which has been successfully used for DNA analysis.2) The PCR amplified anterior 1141 bp product from the CYP21A2 gene was digested by Kpn I, generating 309 bp, 832 bp fragments, not by Taq I, indicating its specificity.3) The frequencies of exon 1 nucleotide 138 A/C polymorphism in Korean population were 0.81, 0.91 respectively, and average heterozygosity was 0.31.4) None of four P450c21 deficient patients turned out to carry complete deletion of the CYP21A2 gene based on selective PCR amplification of the CYP21A2 gene.In conclusion, dried blood spots from Guthrie card can be sued for DNA analysis because of easy sample collection, bandling, shipment, and DNA extraction feasibility. The selective PCR amplification of the CYP 21A2 gene will pave the way for molecular characterization in P450c21 deficient patients. The exon 1 A/C polymorphism can by efficiently used for molecular diagnosis of P450c21 deficiency in informative families, though it has a drawback of handling radioactive material.

The concept of workers' participation in occupational health was introduced to Korea recently in relation to primary health care in occupational health. But there is confusion and debate about workers' participation concept. The purpose of this study was to review the concepts of workers' participation and to conduct evaluation the workers' participation status in occupational health and safety. 394 workers and 54 employers (5.6%) in north area of Kyunggi-Do, were selected and interviewed with a questionnaire by a trained interviewer from August to September 1990. In general, the concept of workers' participation is based on industrial democratization and Declaration of Human Rights which had been powerful ideologies in labor movement. Contrary to workers' participation, community participation is rooted in the Health Rights. So, it is necessary to consider concept of workers' participation to improve participation. The results of survey were as follows: 1. Most of companies (71.75) carried out occupational health education to workers in study area. 2. The Occupational Safety and Health Committee (OSHC) were set up in 24.1% among the study companies, and 72.7% of workers among respondents thought that OSHC was helpful to workers health. 3. The workers signed his name to personal health report in 43.1% and the rate of participation in occupational environment examination was 54.9%. 4. The workers prefer the OSHC (39.3%), owner (35.1%) and union (25.8%) as a occupation health organization, but owners prefer OSHC (54.5%), manager (43.2%) and union (2.3%). 5. Among the factors of the general characteristics, the existence of labor union was a major determinant of workers' attitude and level of workers' participation. As we have seen, most levels of workers' participation are low in occupational health. The variable of existence of labor union among the factors was a major determinant of workers attitude and level of workers' participation. Therefore, in order to promote workers health, it is necessary to ponder long deeply on occupational health care system under the viewpoint of workers' participation.

A 10-year-old boy with arteriovenous malformation (AVM) of the right lower limb was scheduled for an amputation of the affected limb. Limb amputation was necessary because of the ineffectiveness of previous sclerotherapy and the rapid progression of AVM causing pain and heart failure. Right hip disarticulation was considered the best option to improve his quality of life. To prevent congestive heart failure and uncontrollable hemorrhage during surgery, the disarticulation was done under a partial cardiopulmonary bypass. The patient underwent surgery successfully without complications.

PURPOSE: An excess of GH causes various problems within the cardiovascular system including cardiac hypertrophy and abnormalities of left ventricle (LV) function. To evaluate the cardiovascular effects due to GH treatment in idiopathic short stature (ISS), we measured the cardiovascular function. METHODS: Twenty-two echocardiographic studies were performed in ISS who were admitted from Jan. 1994 through Jul. 1996, and they were divided into two groups which revealed in 11 children with GH treatment and in 11 children without GH treatment. RESULTS: The results obtained were as follows, 1) The mean HR in GH group was significantly lower than that of control group (79.9+/-12/min vs. 90.2+/-9/min) (p<0.05), and the mean BP was the GH group 81.6+/-10mmHg and control group 77.7+/-7mmHg. 2) The mean LV isovolumic contraction time (LICT) in GH group was significantly longer than that of control group (35.6+/-3 vs. 32.3+/-2) (p=0.01), but within normal limits. And in GH group, the mean shortening fraction (SF), mean velocity of circumferential fiber shortening (mVcf), and systolic time interval (STI) were 33.9+/-3%, 0.99+/-0.2cir/sec, and 0.15+/-0.04, respectively. In control group, the mean those values were 33.4+/-5%, 0.95+/-0.2cir/sec, and 0.15+/-0.04, respectively. 3) In GH group, the mean isovolumic relaxation time (IRT), peak E velocity (E), peak A velocity (A), and Ea/Aa ratio were 0.05+/-0.01sec, 113.5+/-18cm/sec, 60.5+/-14cm/sec, and 3.9+/-2, respectively. In control group, the mean those values were 0.06+/-0.01sec, 117+/-1.4 cm/sec, 56.8+/-13cm/sec, and 4.7+/-2, respectively. 4) In GH group, the mean cardiac index (CI) and systemic vascular resistance (SVR) were 4304+/-1660ml/min/m2 and 6330+/-764mmHg/ml. In control group, the mean those values were 3835+/-838ml/min/m2 and 6218+/-588mmHg/ml. CONCLUSIONS: These results suggest that the cardiovascular effects did not differ from those in the controls and remained within the normal range after a mean GH treatment duration of 6.2 months.

The influence of serum IgE level on T cell function and number in atopic dermatitis was performed. For the study we selected 2 groups of atopic derrnatitis patients which were 10 cases of atopic dermatitis patients with more than 400 IU/ml of serum 1gE level and 1(l cases with less than 400 IU/ml, The lymphocyte transformation test with phytohernagglutinin and E-rosette test with AET treated sheep cell were perforrned in each group and compare the result of each group with each other and al'o with those of control group. The reults are as follows; l. The mean serum level of IgE in AD(538. 8 407.42 IU/ml) was higher than in normal control(126. 5 133, R8 IU/ml) (p<0.01). 2 The mean LTT S.I. in AD(8.83 -3.85) was lower than in nomnal control (13.99 5.55) (p<0.01). 3. The mean percentage of E-rosette in AD(68,65+6.6g) was lower than 4pp IU/ml(mean+2x SD of serum IgE of control groups), 1) The LTT S, I. was decreased in both groups according to increment of serum IgE, The higher IgE group(8.64+3,9p) had statistical significance compared to normal control(13.gg+5.55) (p<0.01) but not in low IgE group(9.08:4.11).2) The percentage of E-rosette was decreased in both groups according to increment of serum IgE. The both groups of low IgE(71.08.-6,24) and high IgE(66. 22 6. R7) had statistical significance compared to normal control(77.65+4.39 %) (p 0.01).
