The authors clinically analyzed 53 cases of patients beyond 18 years of age with closed solitary femoral diaphyseal fractures, and 24 cases of patients with multiple long bone fractures including closed femoral diaphyseal fracture. All theses 77 cases were followed for more than 1 year, during 1988. 1

Generalized pustular psoriasis is a severe form of paoriasis and is frequently associated with arthritis and nail deformity. We present a case of generalized pustular psoriasis in a 40 year-old man, with nail change, arthritis of both knee and ankle joints, spondylitis, and glomerulonephritis. We found a positive results of HLA A-9, B-27 in this patient. Skin lesions, arthralgia and hematuria improved marked1y by plasmapheresis and application of topical corticostertoid.

Trimazosin Hydrochloride is a new orally active antihypertensive agent derived from the Quinazoline family, related chemically and pharamacologically to parazosin, but unlike its precedecessor, no first-dose syncope has been note, and no tolerance in the management of long term hypertensive patients. The antihypertensive effect of Trimazosin was observed from Oct. 1984 to Mar, 1985 at hospital of Chung-Ang Univesity as outpatient base involving a total 25 patients(Male;16, Female;9)with mild to moderate Hypertension(Diastolic B, P> or =90mmHG but< or =110mmHg). And the average age was 51.5 year(39-66yrs.) Our data demonstrate that 1) Trimazosin is an effective antihypertensive agent for controlling both systolic(166mmHg to 135.7mmHg)and diastolic(102.8mmHg to 85.3mmHg)pressure, and the mean arterial pressure was decreased from 123.8mmHg to 102.1mmHg(P%0.001). 2) We achieved significant sustained reduction in blood pressure with Trimazosin alone in 10 patients, Trimazosin plus Thoazide diuretics in 4 patients, Trimazosin plus-Beta-blocker in 5 patients, and with above triple regimensin 5 patients. 3) Side effects observed during Trimazosin theraphy(mean 3.8 months)appear to be minor and are reflection of its hemodynamic effects, (fatigability 2, dizziness 3, nausea 3 and headache 3) except one had to stop due to severe pounding headache.

The present study was intended to examine the effect of sodium vanadate on contractility of vascular smooth muscle. Aortic ring preparations were made from the rabbit thoracic aorta and endothelial cells were removed from the ring. The contractility of the aortic ring was measured under various conditions. The results were summarized as follows; 1) Sodium vanadate induced contraction of vascular smooth muscle in a dose-dependent fashion. 2) The contractile effects were not blocked by treatments with adrenergic blocking agent(phentolamine) and indomethacin, indicating the direct action of the drug on vascular smooth muscle. 3) In the presence of ouabain, Na(+)-K(+)-ATPase inhibitor, sodium vanadate still increased the contractility of vascular smooth muscle. 4) Treatment with 4.4'-diisothiocyanostilbene-2.2'-disulfonic acid(DIDS) blocked completely the contractile effects of sodium vanadate. 5) In the presence of verapamil, lanthanum and ryanodine, the contractility of the vascular smooth muscle by sodium vanadate was decreased. From the above results. it was suggested that sodium vanadate acts directly on vascular smooth muscle and causes contraction. It was probably due to inhibition of Ca(++)-ATPase in plasma membrane as well as increasing the release of Ca(++) from sarcoplasmic reticulum and Ca(++) influx across the plasma membrane, but not inhibition of Na(+)-K(+)-ATPase.

Caffeine has been known to induce the contraction of rabbit aortic ring resulting from Ca2+ release from the intracellular stores. But in contrast, contraction of aortic ring induced by depolarizing agents or agonist was reported to be suppressed by caffeine. The present study was intended to examine the effect of caffeine on Ca2+ movement across the plasma membrane and actomyosin ATPase activity of vascular smooth muscle to elucidate the modes of action of caffeine on the vascular smooth muscle. Aortic ring preparation were made from the rabbit thoracic aorta and the endothelial cells were removed from the ring by gentle rubbing. The contractilty of the aortic ring was measured under varying conditions, and Ca2+ influx across the membranes of the aortic ring was measured with Ca2+ sensitive electrode with and without caffeine and the effect of caffeine on actomyosin ATPase activity were measured by modified Hartshrone's method. 45Ca wash out curves with and without caffeine were studied by Richard's method. The results were summarized as follows: 1) Caffeine inhibited the contractilty induced by norepinephrine. high K+, and histamine. but caffeine alone induced a transient contraction of vascular smooth muscle. The caffeine induced contraction was demonstrable even in the absence of external Ca2+. 2) Caffeine increased 45Ca efflux from vascular smooth muscle. 3) In the presence of propranolol, the inhibitory effect of caffeine on epinephrine induced contraction still persisted. 4) Caffeine decreased norepinephrine induced Ca2+ influx through the plasma membranes of aortic ring. 5) Caffeine decreased the actomyosin ATPase activity of vascular smooth muscle. From the above results, it is suggested that caffeine induces the contraction of vascular smooth muscle by release of Ca2+ from intracellular Ca2+ stone, but inhibits drug-induced contraction by decrease of Ca2+ influx across the plasma membranes and a decreased Ca2+ sensitivity of contractile protein in vascular smooth muscle.

Osteonecrosis of the femoral head seems to be due to circulatory disturbance of the femoral head, usually idiopathic in origin, but also associated with chronic alcoholism, gout, prolonged treatment with corticosteroids, sickle cell disease, Caisson's disease and surface and degenerative changes in the hip joint. Aims of this procedure are to decompress the femoral head hence allowing better circulation, to revitalize the dead head by insertion of vascularized pedicle bone and to give a mechanical support preventing further collapse of the femoral head. Authors reviewed 19 cases of the vessel pedicled iliac bone graft performed for the idiopathic osteonecrosis of femoral head from January, 1984 to April, 1988 with follow-up periods from 23 months to 66 months, average 37.5 months. The purpose of this follow-up note is to report the long term follow-up result and to show the critical points of this technique.

There has been considerable controversies in the method of the treatment of dislocation of the acromioclavicular joint, especially in grade III injury. It is hard to give a direct firm repair having a short ruptured coracoclavicular ligament. Thats why there are lots of difficulties in the treatment. Therefore, in operative treatment, the authors make use of cotton tape on coracoid process and clavicle as a reconstructive technique, because we have thought a simple fixation of acromioclavicular joint adding to a firm fixation of clavicle and coracoid process is inevitable. From January 1991 to December 1995, twenty-nine cases of grade III acromio-clavicular dislocation were treated by the modified Phemister method with using the cotton tape. Twenty-four patients were followed for an average of fifteen months and the following results were obtained. 1. The clinical results were evaluated by Weitzman criteria after average fifteen months follow up. An excellent result was obtained in 19 cases (79.2%), a good result in 3 cases (12.5%) and a fair result in 2 cases (8.3%), consecutively. 2. Clinical result in patients over 60-year old were bad. 3. The comparison of the coracoclavicular interval ratio before surgery with that after surgery facilitated the evaluation of effectiveness of the coracoclavicular ligament reconstruction. 4. The operative technique is through temporary fixation using K-wires which endows horizontal stability, and it fixes clavicle and coracoid process using cotton tape which endows vertical stability.
