Basement membrane zone gene expression by fibroblast cultures was examined by molecular hybridizations with human sequence specific cDNAs corresponding to type 1V procollagen and laminin subunit polypeptides. Northern transfer analysis with total RNA revealed the presence of specific mRNA transcripts for al (IV) and a2 (1V) chains of type 1V procollagen as well as Bl and B2 chains of laminin. Laminin A chain mRNAs were not detected using the same RNA preparations. The molecular size of al (1V) and a2 (1V) procollagen mRNA revealed 6.8kb and 6.7kb, respectively. The molecular size of Bl chain of laminin revealed 5.6kb, and B2 chain revealed 8.2 and 5.5kb polymorphic transcripts. In slotblot analysis using densitometer, steady-state levels of type IV procollagen and laminin mRNAs indicated that they were in relatively low abunclance, as compaired with type I procollagen mRNA. Quantitative levels of al (IV) and laminin Bl chaii mRNAs were more abundant than those of a2 (IV) and laminin B2 mRNAs. The mRNA ratio of al (IV)/a2 (lV) and laminin Bl/B2 were 1.9 and 1.5, respectively. These results demonstrate evidence for differential regulation of the expression of different basement membrane zone molecules during the formation of basement membrane.

Many authers insisted that the fracture-dislocation of the vertebral column with locked facet, bilateral dislocation of articular facets which resistant to closed reduction, were necessary to posterior stabilization with anterior decompression. But using Harrington-Distraction rod, we experienced that the acceptable reduction of locked facet and posterior impinged bony fragments without anterior decompression, were obtained.

A review of 15 cases of the modified Bristow operation for recurrent anterior shoulder dislocation from Jan. 1983 to Dec. 1988 was presented. Using arthroscopy, we could examined the pathologic feature of the recurrent anterior dislocation of the shoulder. The results are as following. 1. The ages at the initial dislocation were ranged from 15 to 26 years and operated from 19 to 61 years. 2. The most common injury mechanism of the dislocation was sports injury (5 cases) and followings were traffic accident, military training, hanging with one hand. 3. The 10 cases were dislocated above 10 times before operation and 3 were dislocated above 10 times per year. 4. Bony lesions were detected on routine X-ray at 8, that is A-P and lateral view, Hill-sach's view, Stryker-notch view and West point view, Hermoddson view, and apical obique view. 5. Arthroscopic examination was done at 7 cases and could detect the pathologic lesion more exactly. 6. All were treated with modified Bristow method 7. Mean follow up periods were 2 year and 4 monthes. 8. The range of motion was not limited but external rotation was done about 18. 9. Excellent results were obtained by Rowe's grading system, mean 88.8.

Infrahepatic interruption of the inferior vena cava with azygos continuation is relatively infrequent cardiovascular developmental anomaly occurring both in association with congenital heart disease and as an isolated anomaly of no hemodynamic importance. During the past 5 years, we observed 38 cases of infrahepatic interruption of IVC with azygos continuation out of 2,397 cases of congenital heart disease catheterized at Yonsei Cardiovascular Center. We conducted the study with a view point of position of the heart and abdominal organs and segmental analysis of the underlying congenital heart disease. We also analysed the associated exracardiac vascular anomalies The following results wer obtained: 1) The incidence of this anomaly among congenital heart disease was 1.7% and the sex ratio 1.4:1. Twenty four cases(63.1%) was below 5 years of age and 30 cases (79.0%) had cyanosis. 2) We observed 21 cases (55.2%) with the malposition of the heart and 17 cases (44.8%) with malposition of the abdominal organs. The ventricular loops revealed D-loop in 25 cases, L-loop in 5 cases and in the remaining 7 cases, it was uncertain. Eighteen showed normally related great arteries and malposition was present in another 18 cases. 3) Associatcd cardiovascular anomalics wcre as follows: right-sidcd aortic arch: 12 cases, patentductus arteriosus: 10 cases, pulmonic stenosis: 19 cases and bilateral superior vena cava: 9 cases. In conclusion, the presence of this anomaly should alert one to seek the severeintracardiac anomalies which are usually associated with it. Also, it is essential that, if any patient with this anomaly should come to thoracotomy, the azygos vein be not sacrificed.

A 6-year-old male patient had been suffering from angular cheilitis and paronychia with fragmentation and dystrophic change of the finger nails. Laboratory findings showed low serum iron level and anemia. Immunologic studies revealed defects in cell mediated immunity. KOH examination and culture of specimens from the lesions showed hyphal elements and growth of Candida albicans respectively. Concomitantly itraconazole and iron sulfate were administered. Four months after treatment he was free of any clinical evidence of the disease.
