To observe the role of oxygen free radical and enzymatic scavengers in cerebral ischemia, an infarction model was made using transorbital occlusion of the middle cerebral artery in cats. The changes of the superoxide radical production and the activities of superoxide dismutase and catalase were measured. The results were as follows ; 1) The infarction of the left middle cerebral artery(MCA) territory was identified with intracardiac perfusion of a TTC solution after transorbital occlusion. 2) The superoxide radical activities after occlusion of the left MCA were not changed in all groups except for the decrease in 6 hours group of the right side compared to the control group(p<0.05). 3) The Mn-superoxide dismutase activities of the left side in the 12 hours group were significantly higher than those of the right side(p<0.01) and those in the control group(p<0.05). 4) The Cu, Zn-superoxide dismutase activities of the left side in the 3 hours group after occlusion of the left MCA were significantly higher than those in the control group(p<0.05). 5) The catalase activities of the left side in the 3 hours, 6 hours and 12 hours groups after occlusion of the left MCA were significantly higher than those of the right side(p<0.05). 6) The catalase activities of the left side in the 12 hours group after occlusion of the left MCA were significantly higher than those in the control group(p<0.05). The authors suggest that the enzymatic scavangers such as Mn-SOD, Cu, Zn-SOD and catalase increased in the infarcted brain, which means an involvement of free radicals in cerebral infarction.

A retrospective study 40 patients with moderate or severe diffuse axonal injury which is defined as posttraumatic coma for over 24 hours without mass lesions or ischemic insults was conducted in order to identify prognostic parameters. The sign of hypothalamic damage and motor reactivities of 40 patients were reviewed and compared to the outcome. The results were as follows ; 1) The ratio of male to female was about 3 to 1 and the peak incidence was at the first decade. 2) Of abnormal brain stem signs, fever of central origin was observed at the early posttraumatic phase and correlated with nonrecovery of consciousness(P<0.05). 3) Of abnormal brain stem signs, abnormal ADH secretion was significantly correlated with nonrecovery of consciousness(P<0.005). 4) Abnormal motor reactivity to pain was significantly correlated with nonrecovery of consciousness(P<0.005). 5) In the group of recovery of consciousness, initial Glasgow coma scale in 40 patients with moderate or severe DAI was significantly correlated with their outcome(P<0.005).

The use of subcutaneously tunneled, cuffed central venous catheters like Broviac's or Hickman's has increased and complications related to catheter removal has also increased. However, there are only few reports of complications that occur at the time of removal. The authors report an unusual case of catheter fracture during removal of Broviac catheter.

Superficial gastritis has been classified as a type of chronic gastritis, since a report of Schindler in GASTRLTIS, 1947. Howev~er, Benedict reported that superficial gastritis is only acute gastritis or shows normal mucosa histologically. The com mon endopical findings of chronic superficial gastritis were adherent mucus, edema, redness. The common redness which were encounterd are patchy redness and comb-like redness(Kammrotung). We studied the relationship between the redness of superficial gastritis and acute inflammatory changes histologically. Each case of superfieial gastritis was biopsied to redening and non-redening mucosa respectively. We collected 24 cases with 48 biopsy specimens. The results are as follows: Acute inflammatory changes were found only one case in redness and none in non-redness groups. There was no difference in acute inflammatory changes in two groups. The degree of mucosal atrophy were 62.5%, 66.7% in normal mucosa, 12.5%, 16.7~% in mild atrophy, 25%, 12.5% in moderate atrophy, 0%, 4.l% in severe atrophy with respect to redness and non-redness mucosa respectively. There was no difference in degree of mucosal atrophy in two groups. Mucosal atrophies were higher in older ages above 41 years old than below 40 and with increasing age, there was increasing tendency of mucosal atrophy. In conclusion, There was no relationships between mucosal redness and acute in flammatory changes histologically and also between mucosal redness and degree of atrophy.

10.The Effects of ADCON(R)-L on the Adhesion after Strabismus Surgery.
Journal of the Korean Ophthalmological Society 2003;44(1):208-214
PURPOSE: We investigated the effectiveness of ADCON-L in reducing the formation of adhesion after strabismus surgery in a rabbit model. METHODS: Bilateral recessions of superior rectus muscle (SR) were performed on 18 rabbits. ADCON-L was applied beneath and over the SR in 9 rabbits, while operative fields in the others were irrigated with a balanced salt solution (BSS). The degree of adhesion was recorded at 3 weeks postoperatively. All eyes were enucleated and histopathologic examination was done at 4 weeks postoperatively, and the degree of fibrous proliferation and inflammation were evaluated. RESULTS: A significant reduction in the degree of adhesion and fibrosis was noted in eyes treated with ADCON-L as compared with in those irrigated with BSS (p=0.003, p=0.028). However there was no statistical significance in the degree of inflammation between two groups (p=0.114). CONCLUSIONS: This study suggests that ADCON-L is effective in reducing postoperative adhesion for as long as 4 weeks after strabismus surgery in rabbits.
