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.

A clinical study of 147 clavicle fracture patients (one patient had bilateral fractures) who were admitted and treated by the Department of orthopedic surgery of Wonju Christian Hospital, Wonju Medical College, Yon Sei University. The period covered was from September 1974 to August 1981, a total of seven years. The study focused on three fertors in relation to the pain and limitation of motion and these causes were comminution of fracture, shortening of the clavicle length and external deformity. The results were as followings; l. Of the 148 cases, 125 were male and 22 female (one with bilateral fractures). The majority were between 31 and 40 years of age. 2. The mid 1/3 fracture was most common and both sides showed no difference in incidence(left ; 73 cases, right; 75 cases). 3. The mean follow up ranged from 4 months to H3 months with a mean 49.5 months. 4. The complications resulting from comminution, shortening of clavicle length and malunion were shoulder joint pain-16 cases (10.8%), limitation of motion-17 cases(11.5%) and external deformity-18 cases(12.9%). 5. Using a rating scale of excellent(no apparent factors), good( one factor), fair(two factors), poor(more than three factors) the results showed, 106 excellent, 31 good, 9 fair and 2 poor. 6. On a percentage scale, the pain showed difference of 9 times with initial comminution, 7 times with shortening of clavicle length and 7 times with deformity. 8. On a percentage scale, the limitation of motion of shoulder joint showed difference of 6 times with initial comminution, 6 times with shortening of clavicle length and 17 times with deformity.

Aneurysm of the superficial temporal artery is rare. We reviewed seven cases of aneurysm of the superficial temporal artery, which were confirmed surgically and angiographically. The results were as follows: The most common site of aneurysm was left superficial temporal artery, major feeding artery was anterior branch of superficial temporal artery, mean diameter was 7.8mm×12.6mm, and all aneurysms showed lobulated margin with intraluminal filling defects.

Background: Post-dural puncture headache (PDPH) is one of the well-known complication of spinal anesthesia. Epidural blood patch is the treatment of choice for PDPH but is rarely used for the prevention of PDPH after spinal anesthesia. The purpose of this study is to observe the effectiveness of epidural blood patch for prevention of PDPH and to evaluate the complications after epidural blood injection. Methods: Three hundred patients (ASA I or II) receiving spinal anesthesia were studied. They were randomly devided into two groups. Patients in Group I, the control group, were maintained in a supine position for 24 hour after spinal anesthesia. Patients in Group II, the study group, received 3 ml of autologous blood in the epidural space after spinal anesthesia. PDPH was evaluated for 5 days. The incidence, location, onset, and duration of headache in the patients presenting with PDPH were measured for 5 days, and the complications following epidural blood patch in Group II were observed for 2 weeks. Results: The incidence of PDPH in group I was 11%, but 0% in group II. There were no specific complications following epidural blood patch in Group II. Conclusions: This study suggest that the 3 ml epidural autologous blood patch is an useful method for the prevention of PDPH in patients with spinal anesthesia.
