A tumor of the neuromyoarterial apparatus, the glomus, was described by Masson : the epitheloid cell of glomus was derived from the pericyte of Ziemmermann and these cells were widely distributed in the body. From Jan. 1987 to Oct. 1993, six patients (male 1, female 5), who were diagnosed as a glomus tumor in the hand were operated. The lesions were distributed in the distal phalanges of thumb (3 cases), index (1 case), ring finger (1 case) and little finger (1 case). The average duration of clinical manifestation was 6.3 year. Nail extraction was performed because of pain in 2 cases, but symptom was not improved. The clinial symptoms were severe lancinating pain, tenderness and cold induced pain in all 6 cases, palpable mass in 2 cases, bluish purple discoloration of skin in 4 cases, subcutaneous hemorrhage in 1 case, swelling in 2 case. On the reontgenography, bone changes were detected in 2 cases, soft tissue change was detected in 1 case and 3 cases showed unremarkable findings. The treatments were simple excision in 5 cases,curettage and bone graft in 1 case and symptoms were improved in the 6 case with the remnant mild pain and there was no recurrence. The aim of this study was to report the rare cases of glomus tumor in the hand.

There are several different methods of purifying Treponema pallidum(TP) from rabbit testicular tissue. Among them, we compared the use of differential centrifugation, which has been most widely used, to Percoll density gradient centrifugatian, a newly applied method, in purifying TP from rabbit testicular tissue by checking the protein concentration of the TP suspension, hemagglutination assay using sheep erythrocytes sensitized by TP, IgM-TP-enzyme-linked immunosorhent, assay(IgM-TP-ELISA) and eJect,ron microscopic observation. The protein concent,ration af TP antigen suspension (2x10(8)TP/ml) purified by Percoll density gradient centrifugation (lower band) was the lowest (129.0pg/ml) when compared to those purified by differential centrifugation (324.0pg/ml) and Percoll density gradient centrifugatian (upper band) (560.2pg/ml). Sheep erythrocytes sensitized by TP purified by Percoll density gradient centrifugation(lower band) showed the same resiilts as those using a commercii1 TPHA kit when tested with positive and negative control sera. The sensitivity and specificity of the IgM-TP-ELISA were 88.5%(23/26') and 86.4%(19/2Z) respectively using TP as an antigen purified by differential centrifugation. The rates were 96.29% (25/26) and 95.5%(2l/22) using TP purified by Percoll density gradient centrifugation. As shown by the electron microscopy, T. pizllida purified by clifferential centritugation and Percoll density gradient centrifugatiori were structurally unaltered, and Percoll-purified TP contained much less tissue debris than TP prepared by differ ential centrifugation. Therefor e, Percoll density gradient centrifugation is considered to be a better method of purifying TP from rabbit testicular tissue when compared to differential centrifugatian, as a matter of fact, Perrol1 density gradient centrifugation has been applieci successfully in the study of the physiology, recombinant DNA techniques, and antigenic structure of TP and to the preparation of the antigen for the FTA-ARS and TP-ELISA

Fifteen shoulders in 15 patients with traumatic recurrent anterior dislocation were performed from Sept. 1993 to April 1994. The position in which the dislocation occurred were abduction and external rotation in 10 cases, but most likely direct injuries in the 13 cases. The average interval between the initial and second dislocation was 5.4 months, and the average frequency of dislocation was 15 times per year. Physically, crank test in 13, fulcrum test in 12, sulcus test in 4, and jerk test in 3 cases were positive. The classic Bankart lesions were 4 cases, the bony Bankart lesions in 11 cases, so all of them had an abnormal tension on the inferior glenohumeral ligament. The Hill-Sachs lesions were associated in 14 cases, the Superior Labrum Anterior Posterior lesion in 1 case. Traditional Bankart procedure in 12 cases, traditional method and shift surgery simultaneously for inferior laxity in 3 cases were performed. In 4 cases of bony Bankart lesion with large bone fragment, anterior capsule and subscapularis muslce was splitted during exposure. Velpeau sling was applied in a daytime for postoperative immobilization, exercise with 90° of flexion but no external rotation was permitted during 3 weeks after operation. After than 140° of flexion and 40° of flexion and averag 57° of external rotation. There was no recurrence in our series. The result at follow up were exellent in 9 cases, good in 6 cases.

Indications for bone lengthening in the hand are less common than for the lower extremity. From 1991 to 1993 authors had performed nine hand bone lengthenings in the eight patients, based on callotasis and chondrodiastasis, Average age at the time of surgery was 18 years old(from 4 to 31 years old). Diagnoses included traumatic amputations in 7 cases and congenital syndactyly of both hand with hypoplastic digits in 2 cases. Sites of lengthening were metacarpal bone in 7 cases, phalangeal bone in 2 cases. Eight of 9 lengthening procedures resulted in complete consolidation of the bone gap after the single stage procedure. In one case secondary bone graft was required for the bone defect. Average consolidation period was 16 weeks(from 10 weeks to 22 weeks). Average gained length was 14.6mm (from 6 to 30mm) and average percent of gained digital bone length was 48%. There were minimal complications including marginal necrosis of skin, numbness and bone tip exposure and were responsed to conservative manage, but stump revision for bone tip exposure was performed in one case. In all cases followed to completion and for 1 to 3 years postoperatively, there was improvement of function with key pinch. The callotasis lengthening is one of the useful method of short hand bone lengthening to improve function of hand and cosmetic demand.

To assess the efficacy of 2 different mitral balloon valvotomy (PMV) techniques, PMV was performed using Inoue balloon (I) in 35 pts and double balloon (D) in 33 pts with mitral stenosis (male 27, female 41, mean age 42+/-12 years). The success rate of PMV was 89%(31/35 pts) in I group and 97%(33/33 pts) in D group. Mitral valve area after dilation increased equally effectively in both groups (I and D) from 0.9+/-0.2 and 0.8+/-0.2 to 1.9+/-0.2 and 1.9+/-0.3cm2 respectively (p<0.0001). There were no differences in degree of improvement of cardiac output, mitral gradient, left atrial pressure, pulmonary artery pressure and various doppler echocardiographic findings in both groups, but EF slope was more improved from 13+/-7 to 48+/-16 mm/sec in D group than those (from 15+/-6 to 39+/-15mm/sec) of I group. Increments of long and short diameters of mitral valve orifice by 2D-echocardiogram were 1.1+/-0.6 and 0.3+/-0.3cm in D group and 0.9+/-0.5, 0.4+/-0.3cm in I group. The ratio of long and short diameter increase was significantly larger in D than that of I group (long/short 2.8+/-0.7 vs 2.4+/-0.7, p<0.05) and short diameter of orifice after dilation was more improved in I than that of D group (1.1+/-0.2 vs 1.0+/-0.2cm p<0.05). Complications included deflation failure of Inoue balloon in 2, and cerebral embolic episode in 1 (D). Incidence of increased mitral regurgitation was 50% in D and 45% in I, development of ASD (Qp/Qs>1.2) was 20% in D, 13% in I group respectively and mean amount of left to right shunt (Qp/Qs) was 1.7+/-0.3 in D and 1.5+/-0.1 in I group. Total procedure and fluoroscopic time were 84+/-24 and 25+/-11 min. in D and 56+/-20 and 16+/-6 min. In I, which had statistically significant differences (p<0.002). Thus we concluded PMV using Inoue or double balloons was equally effective in selected patients. Total procedure and fluoroscopic time of Inoue balloon technique were significantly shorter than those of double balloons. Double balloon technique had more tendency of longitudinal splitting of the commissures.

BACKGROUND: The purpose of this study was to investigate the mechanism of endothelium-dependent and independent responses to endothelins (ETs) in porcine coronary artery. METHODS: The vascular rings of left anterior descending artery or left circumflex artery from 7 pigs were suspended in conventional organ chambers for the measurement of isometric force. To evaluate relaxation responses, vascular rings with endothelium were exposed to ET-1 and ET-3. To evaluate contraction responses, vascular rings with and without endothelium were exposed to ET-1 and ET-3 in the presence or absence of BQ 123 (ET(A) receptor antagonist) or TAK-044 (ET(A) and ET(B) receptor antagonist). RESULTS: Transient relaxation responses of vascular rings occurred after exposure of ET-1 and ET-3. These transient responses disappeared after preincubation with N-nitro-L arginine. There was an increased contractions of vascular rings according to increasing concentration of ET-1 and ET-3. The initial responses were enhanced in vascular rings without endothelium in ET-1 and ET-3. In vascular rings with endothelium, the contraction responses were more reduced in vascular rings with preincubation of BQ 123 than in vascular rings without BQ 123 in ET-1. In vascular rings without endothelium, the contraction responses were more reduced in vascular rings with preincubation of TAK-044 than in vascular rings without TAK-044 in ET-1. CONCLUSION: ET(B) receptor on the endothelium might mediate the transient vasodilator responses to ET-1 and ET-3 through release of nitric oxide in porcine coronary artery. ET(A) and ET(B) receptor on vascular smooth muscle cells might mediate vasoconstrictor responses to ETs.
