GABA is an inhibitory neurotransmitter in central nervous system and produce sedative, antianxiety and muscle relaxing effects via GABA(A) receptor or GABA(B) receptor. Recently it is known that GABA is widely distributed throughout peripheral organs and may play a physiological role in certain organ. The vas deferens is innervated by species-difference. These study, therefore, was performed to investigate the mode and the mechanism of action of GABA on the norepinephrine-, ATP- and electric stimulation-induced contraction of vas deferens of rat. Sprague-Dawley rats were sacrificed by cervical dislocation. The smooth muscle strips were isolated from the prostatic portion and were mounted in the isolated muscle bath. PSS in the bath was aerated with 95/5%-O₂/CO₂ at 33℃. Muscle tensions were measured by isometric tension transducer and were recorded by biological recording system. 1. GABA, muscimol, a GABA(A) agonist, and baclofen, a GABA(B) agonist inhibited the electric field stimulation (EFS, 0.2Hz, 1mSec, 80V, monophasic square wave)-induced contraction with a rank order of potency of GABA greater than baclofen greater than muscimol. 2. The inhibitory effect of GABA was antagonized by delta aminovaleric acid (DAVA), a GABA(B) antagonist, but not by bicuculline, a GABA(A) intagonist. 3. The inhibitory effect of baclofen was antagonized by DAVA, but the effect of muscimol was not antagonized by bicuculline. 4. Exogenous norepinephrine (NE) and ATP contracted muscle strip concentration dependently, but the effect of acetylcholine was negligible and GABA did not affect the NE-and ATP-induced contractions. 5. GABA, baclofen and muscimol did not affect basal tone, and GABA did not affect the NE-and ATP-induced contractions. 6. EFS-induced contraction was inclucling 2 distinctable components. The first phasic component was inhibited by beta gamma-methylene ATP (mATP), a desensitizing agent of APT receptor and the second tonic component was reduced by pretreatment of reserpine (3 mg/Kg, IP). 7. GABA inhibited the EFS-induced contraction of reserpinized strips, but not the mATP-treated strips. These results suggest that in the prostatic portion of the rat vas deferens, adrenergic and purinergic neurotransmissions are exist, and GABA inhibits the release of ATP via presynaptic GABA(B) receptor on the excitatory neurons.

Prediction of acetabular development after reduction in treatment of developmental dysplasia of thc hip (DDH) is earlier, the hetter results because it would help ensure optimal timing of additional procedure if necessary. In this respect, authors reviewed retrospectively the radiographs of the hips of 35 children with DDH who had unilateral involvement and treated hy senior author (S.H.Lee) from the heginning with single successful attempt of reduction. The radiographs which were made at the time of initial diagnosis, one, two year nfter reduction und final follow up were assessed of teardrop figures. The results of treatment were classified as satisfactory group(CE > 10degrees ) and unsatisfactory group(CE < 10degrees) judged hy center-edge angle(CE degrees) at final follow-ups. 1. The teardrop figures were classifiable into 4 distinct groups as i)absent. ii)V-shaped, iii)Ushaped, iv) inverted D-shaped. 2. The teardrop figures in normal sides of hip were all U-shaped. 3. In dislocated but with satisfactory result group(24 cases), absent at 2 cases(8%), U-shaped teardrop was seen at 13 cases(54%), V-shaped in 9 cases(38%), and inverted 2-shaped in 0 case at I year after reduction. 4. In dislocated but with unsatisfactory result group( 11 cases), they were mostly of V-shaped(7 cases, 64%). The rest were of ahsent in 4 cases(36%) . hut none of U-shaped and inverted 2-shaped. In conclusions, teardrop figures appeared as significant predictor of future development of hip joint. Teardrop figure which stay as V-shaped at one year after reduction seems suggestive of insufficient reduction of DDH, therehy calls for early additional procedure.

Bronchiolitis obliterans is an infrequent disorder characterized by partial or complete obstruction of bronchi and bronchioles by fibrous tissue following an insult to the lower respiratory tract. In the pediatric population, Bronchiolitis obliterans has most frequently been preceded by respiratory tract infection by adenovirus, influenza, measles. But it may occur in young adults after mycoplasma infection. We experienced the case of Bronchiolitis obliterans, which developed after the onset of Stevens-Johnson syndrome due to Mycoplasma pneumoniae infection and present a brief review of the related literature.

Emergency endoacopy was performed in 315 patients for recent four years The source of upper GI bleeding in these 315 caaes were as follows: Esophageal varix(93), gastric ca(39), Mallory-weiss syndrome(14), gastric ca(38), Duodenal ulces(21), Erosive gastritis(14), Marginal ulcer(2), Combined case(24) Unknown cases(10), Essentiall Tx was not performed in 4 died case because of poor general conditions, After check up BP, Heart, Pluae rate, that examination was performed during drip infusion to be 'safety of cireulatary system. No compication were encountered. To confirm the source of bleeding at earlier stage, was useful to decid which way, that is conservative of surgical therapy in which better for the Management. The results are as follows: 1) The sex incidence of upper GI bleeding showed Male predominance c a ratio 4. 6: 1 and peak age groups were 4th & 5th decade. 2) Endoscopic diagnosis of npper GI bleeding in the studied case were in the order of Esophageal varix bleeding(29%), Gastric ulcer (23. 5%), Mallory weiss syndrome(12. 4%) Duodenal ulcer(6.7%) Erosive gastritis(4.4%) We could not find the bleedi site in 3.2% of the studied case. 3) The cause of emergeney endoseopy are Melena(19%), Hemstenesis(22.0%) and ccenbined (58. 4%) 4) Among the 315 cases of upper GI bleeding, 70. 1% of the cases revealed moderste degree of bleeding. 5) Among the 315 cases of apper BI bleeding, 28. 1% of the cases were confirmed of inducing factor. 6) Among the 315 cases of upper BI bleeding, 69% of the cases received an endcrscopic examination within 72 hr after initial episode of bleeding.

While anomalies of the pancreaticobiliary system are not uncommon, drainage of the common bile duct into the bulb of the duodenum has rarely been reported. The awareness of ectopic drainage of the CBD is stressed to prevent surgical damage and improve medical management in this area. We reported one case of anomalous drainage of the CBD and pancreatic duct associated with nonvisible gallbladder or agenesis of gallbladder and cystic duct diagnosed by ERCP, ultrasonography and upper abdominal CT.
