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.

BACKGROUND : The recent studies shows that Helicobacter pylori (H. pylori) related chronic gastritis leads to dysplasia, intestinal metaplasia and gastric cancer. The aim of this study was to determine the association between precancerous lesion of stomach (dysplasia, intestinal metaplasia) and H.pylori infection in the elderly. METHODS : 469 patients were enrolled this study, Patients with intestinal metaplasia or dysplasia (case, n=148) were compared with controls (without intestinal metaplasia and dysplasia, n=321) about H. pylori positive rates H. pylori positivity was confirmed by histologic determination of endoscopic biopsy specimens. Results : 1) Among study populations H. pylori positive rates were 51.8% (55.8% in male, 40.7% in female). It was significantly higher in male (p=0.001). 2) There were no significant differences in sex distribution between cases and controls, but in old age, the cases were more frequent than in young age (p<0.001). 3) Age distribution of H. pylori positive rates were not significant between cases and controls. 47.5% in intestinal metaplasia, 43.4% in dysplasia, 21.3% in dysplasia+intestinal metaplasia were H. pylori positive. H. pylori positive rates were more higher in controls than cases, followed by in decreasing order by the intestinal metaplasia group, the dysplasia group, and those having both (p=0.003). 4) Age and sex adjusted H. pylori positive rates were more higher in controls (42.7%) than in cases (25.0%)(p<0.009). CONCLUSION : The prevalence of intestinal metaplasia and dysplasia was age dependent. But we couldn't explain the carcinogenic effect of H. pylori, because H. pylori positive rates were lower in cases than in controls

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.
