A case of traumatic myositis ossificans arising from both elbow joints in twenty six year old male is reported. This patient had been confined to his bed in comatous state for three months after head trauma by traffic accident. When he awaked from coma, the patient noticed his both elbows stiff. Roentgenograms of both elbows revealed extensive irregular periarticular ossifications around the joints. At posttrauma tenth month, complete excision of the bony mass was carried out from the left elbow and one month later, from the right one. From postoperative one week, active exercise was started. Duration of follow up was seven months in left side and six months in right side, There are no signs of recurrence and, now patients go through satisfactory range of motion of both eldows.

The authors have reviewed 71 cases (70 patients) of the ankle fractures that were treated through the admission in Orthopedic Department, Paik Foundation Hospital, from June 1972 to April 1978. The average duration of the follow-up waa 15 months. The summary of the results were as follows; 1. Of the 71 cases, male was 54 cases and female 17 cases. The average age of the patients was 32. 2. The main cause of the injuries was traffic accident, and the other causes were sliding down and falling from a height, industrial accident, and sports injury in order. 3. By the classification of Lauge-Hansen, the pronation-external rotation and,supination-adduction types were commoner than the other types. 4. Open reduction was performed in 48 cases, and closed reduction in 23 cases. 5. The average duration of the cast immobilization after the closed reduction was 8 weeks, and that of the open reduction was 6 weeks. 6. The result of the treatment was better in those cases of the open reduction than that of, the closed reduction. 7. The good clinical results could be achieved by obtaining the anatomical position of the talus in the mortise and the reduction was achieved more satisfactorily when the key role of the lateral malleolus in complete reduction was well understood.

The objective of the present study was to examine the effects of beta-glucan originating from Aureobasidium on full-thickness skin wound healing in diabetic C57BL/KsJ-db/ db mouse models. In the diabetic C57BL/KsJ-db/db model, test articles were topically applied twice a day for 20 days starting from 1 day after wounding. The results were compared to that of MadecassolTM ointment (madecassol; 1% Centella asiatica extracts) topically applied at a concentration of 100 mg/kg. Treatment with beta-glucan resulted in significant (p<0.01 or p<0.05) and dose-dependent decreases in wound size compared with that of vehicle control showing increased wound size (WS, %). In addition, 50% contraction time (CT50) was dramatically and dose-dependently reduced, and inflammatory cells in granulation tissues of the wound area were significantly (p<0.01 or p<0.05) and dosedependently reduced compared with that of vehicle control showing increased numbers of micro-vessels and fibroblasts as well as re-epithelialization. In the madecassol group, similar changes in inflammatory cells and fibroblasts with re-epithelialization were also observed, but madecassol did not influence angiogenesis. No meaningful changes in body weight were detected in all tested groups compared with the vehicle control. Therefore, these data suggest that beta-glucan has a beneficial effect on diabetic delayed skin wound healing and may be useful to manage incurable skin wounds in diabetic animals.

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.
