PURPOSE: To define the histologic correlation of the ultrsonic gastric wall layers of resected human gastric specimens. MATERIALS AND METHODS: UItrasound images of the gastric wall by using 5 or 7.5 MHz linear transducer were compared with the corresponding histologic sections of 30 surgically resected human gastric specimens. RESULTS: Five layers seen from within on ultrasound images of the normal gastric wall corresponded to (1) the acoustic interface between fluid bathing the surgical specimen and the mucosal surface and a portion of the superficial mucosa, (2) the deep mucosa including the muscularis mucosae and most of the superficial mucosa, (3) the submucosa plus the acoustic interface between the submucosa and the muscularis propria, (4) the muscularis propria minus the acoustic interface between the submucosa and the muscularis propria, and (5) the serosa and the subserosal tissue plus the acoustic interface between the serosa and the fluid bathing the surgical specimen. Ultrasonic findings in gastric carcinomas corresponded to their histopathologic findings. CONCLUSION: Histologic correlation of the ultrasonic gastric wall layers will provide us with a very useful and objective basis of gastric ultrasonography.

We studied the serum electrolytes in the 727 normal persons who visited Busan University hosptial, Benedict Hospital and Maryknoll Hospital from 1970 to 1976. The results were as follows: 1. Mean value of the serum Na+ being measured in 729 normal persons was 138.7+/-6.2mEq/L and 140+/-6.5mEq/L in 450 male, while 136.8+/-6.6mEq/L in 279 female. 2. Mean value of serum Cl- being measured in 701 persons was 99.6+/-5.9mEq/L, and 99.7+/-6.0mEq/L in 437 male while 100+/-5.7mEq/L in 264 female. 3. Mean value of serum K+ being measured in 707 normal persons was 4.4+/-0.9mEq/L in 434 male, while 4.2+/-0.8mEq/L in 273 female. 4. Mean value of serum Ca+ being measured in 557 normal persons was 4.5+/-0.6mEq/L and 4.7+/-0.7mEq/l in 355 male, while 4.3+/-0.5mEq/L in 202 female. 5. Mean value of serum phosphorus being measured in 94 normol persons was 4.2+/-0.6mg%, and 4.1+/-1.0mg% in 65 male, while 4.5+/-1.5mg% in 29 female.

Five patients with obstruction of the hepatic portion of the inferior vena cava diagnosed by digital subtraction inferior vena cavography were reported. All of these patients, aged from 38 to 52, were female who had never used the oral contraceptives. Main collateral pathway of these patients was the central channels through ascending lumbar veins, internal and external vertebral plexuses, azygos-hemiazygos complex, and inferior vena cava itself above the obstructed segment.

The authors, in this paper, addressed a variety of problems and difficulties which Korean psychiatrists should cope with. The surprising development of neurosciences, splitting of neuropsychiatry into neurology and psychiatry, easygoing attitude of psychiatrists, changes in the delivery system of health care and ill-balanced education of psychiary were listed as causes of or contributors to them. Social bias to psychiatry and regulations from outside are also considered as contributors. Psychiatric education, including medical school, residency training, continuing medical education and psychiatric textbooks, need to be changed in order to enlarge the boundary of psychiatry. Reestablishment of identity of psychiatry and psychiatrist is unavoidable, considering far-reaching new knowledge of neuroscience and gradually invisible borderzone between neurology and psychiatry. The other ways worth while to consider are : the expansion of psychiatrists' activities, development of medical behavioral science to a clinical specialty, creation of new psychiatric subspecialties, and additional training of psychiatric residencies in the primary medical care.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.

Recent development of oral and maxillofacial surgery has taken an interest in the regeneration of facial bone defects. For the reconstruction of bony defects, autogenousbone grafts have been widely used. However, there are some clinical problems ; the morbidity of donor sites, resorption of autogenous bone graft and the availability of the proper form and size. The purpose of this study is to find the proper filling materials for the bone defects. The present study was designed to evaluate the roles and regenerating capacity of maikture of freeze-dried domineralized allogenic bone and hydroxylapatite. Fifteen adult New Zealand white rabbits were used as the experimental animal, Four trephine defects were made by drilling on the parietal bone of each rabbit. The size of each defects was 8x8mm. In first group, the defect was filled with freeze-dried demineralized allogenic bone and hydroxylapatite. The defect in second group was filled with autogenous bone chip only. The third group was filled with autogenous bone chip and hydroxylapatite. The fourth group was filled with freeze-dried dimineralized allogenic bone only. The results were carefully examined grossly and micorsocopically from the 2 weeks to 12 weeks postoperatively. The following results were obtained ; 1. In the case of the graft with autogenous bone chip only, new bone formation was more active than any other groups. 2. In the case of the graft with combination of freeze-dried demineralized allogenic bone and hydroxylapatite, new bone formation was similar to the case of autogenous bone and hydroxylapatite mixture. 3. In the case of the graft with freeze-dried demineralized bone, new bone formation was observed, but less than the other groups. And the time of new bone appeared was later than the other groups. A combination of freeze-dried deminearalized allogenic bone and hydroxylapatite plays an effective role in forming new bone. The results of this study may suggest the possible usage of the mixture of freeze-dried allogenic bone and hydroxylapatite as an alternative to autogenous bone in maxillofacial orthopedic surgery.

Genes encoding sequence-specific DNA binding proteins have been isolated by screening cDNA libraries constructed in rgt11 expression vector with recognition site DNAs. We isolated a rgt11 recombinant human cDNA clone, designated to C2, using a DNA probe consisted of heptamer of the perfect palindrome (PP; GGGGATTCCCC) of enhancer A (Enh A) of HLA dass I promoter. Sequencing analysis showed that this clone contained a partial cDNA homologous to NF-kB2. Lysogenic E. coli containing the C2 was generated and crude cell extract was prepared. Immunoblot using anti-B-galactosidase antibody showed that this lysogenic E. coli expressed B-galactosidase fusion protein. Electrophoretic mobility shift assay (EMSA) and DNase I footprinting assay were done using crude cell extract and their patterns were compared with nuclear protein extracted from an EBV transformed B lymphoblastoid cell line (BLCL). EMSA showed that crude cell extract prepared from E. coli lysogen speci5cally bound to the PP of Enh A region of HLA class I gene. DNase I footprinting assay showed that the binding sequence of this recombinant B-galactosidase fusion protein was identical to that of nuclear protein extracted from a BLCL. Our data indicate that a Agt11 recombinant cDNA clone was isolated from a human cDNA library using the PP of Enh A of the HLA class I promoter and this clone encoded a B-galactosidase fusion protein capable of binding to the PP and belongs to a NF-xB subunit.
