The role of limbal epithelial cells on the initial re-surfacing of the central epithelial defect was evaluated. Central or peripheral corneal wounds were produced by using n-heptanol in New Zealand white rabbit, and the epithelial healing rates were evaluated. Central corneal wounds made by applying a filter paper soaked in 0.2 N NaOH with vs without limbal damage were produced for the paralleled set of experiment. A 5.5 mm round filter paper for central wound and a 2 mm filter paper strip for limbal damage were used for the initial wounding. Epithelial defect areas were photodocumented after fluorescein stainmg at 0.6, 18, 30, 42, 48 hours following initial damage. Epithelial healing rates were measured by linear regression analysis, The epithelial healing rates of central and peripheral heptatlol wounds were 0.71 +/- 0.14 mm2/h, and 0.79 +/- 0.10 mm2/h(p>0.05), respectively, NaOH central wound without limbal damage and with limbal damage were 0.77 +/- 0.11 mm2/h, and 0.76 +/- 0.11 mm2/h, respectively(p>0.05). These data suggest that the limbal epithelium has no influence on the initial re-surfacing of the central epithelial defect.

Levocabastine, a selective H1-receptor antagonist, has been evaluated in the management of allergic conjunctivitis and its efficacy was compared between the skin test positive and negative groups. A total of 20 patients who was clinically diagnosed as allergic conjunctivitis were processed for the skin test. According to the results of skin test, patients were divided into two groups; skin test positive (15) and negative (5). Livostin(levocabastine 0.5mg/ml) eye drops were topically instilled 2 times per day for 1 week. Both subjective and objective findings were assessed by a 4-point scase (0=none, 1=mild, 2=moderate, 3=severe). The parameters used for the examination of drug effectiveness were itching, tearing, chemosis, lid swelling and injection. 85.5% (17 put of 20) of the patients showed effects on the management of their symptoms and signs. No significant difference was observed in its effectiveness between skin test positive and negative groups. The results of present clinical trials suggest that Livostin eye drops may be an attractive therapeutic option for the management of allergic conjunctivitis.

Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.

The effects of topical dexamethasone on the endothelial healing and the change of aqueous composition were examined in the repair process of experimental corneal alkali wounds. Corneal alkali wounds were induced, then the eyes were treated topically with either 0.1%dexamethasone or abalanced salt solution[BSS]4 times per day for 8 weeks. Endothelial wound morphometry was performed after alizarin red and trypan blue staining. The concentrations of ascorbic acid, glucose, and the ions, Na, K , Ca2 and Mg2 , were measured in the aqueous humor. Endothelial healing in control corneas showed a biphasic pattern of healing:an initial short-term healing for the first week and then a late long-term healing following a secondary endothelial breakdown. Topical administration of 0.1%dexamethasone deterred endothelial healing during the early period and prevented secondary endothelial breakdown. Total repair process of endothelium was accelerated by the dexamethasone treatment. Among the various components of the aqueous humor examined, ascorbic acid seemed most sensitive to change caused by the alkali injury and dexametha-sone treatment. The present data indicate that dexamethasone may have a therapeutic potential in the management of endothelial healing after corneal alkali injury.

OBJECTIVES: Hemodynamic measurements of chronic portal hypertension were done to study the mechanisms that maintain high portal pressure despite well developed collateral circulations. METHODS: A prehepatic portal hypertensive rat model was produced by partial portal vein ligation. Cardiac output, organ blood flow and porto-systemic shunt were measured by radioisotope labeled microsphere methods, and vascular resistance was calculated by standard equation. RESULTS: There was a significant reduction in the weight of the liver and increase in the weight of the spleen in the portal stenotic rats. Porto-systemic shunting, representing development of the collateral circulations, was 96.7+/-0.6% in the portal stenosis group compared with 0.9+/-0.2% in the control group (p<0.01). Portal pressure was significantly increased in the portal stenosis group compared with the control group(12.8+/-1.4 vs. 6.5+/-0.6mmHg; p<0.01). Mean arterial pressure was significantly decreased in portal stenosis group compared with control group(101.4+/-2.5 vs, 129.9+/-3.9mmHg; p<0.01). In the portal stenosis group, cardiac output(135.7+/-8.0 vs. 111.0+/-4.2ml/min; p<0.01) and splanchnic organ blood flow (28.97+/-2.03 vs. 17.90+/-1.27ml/min, p<0.01) were significantly increased, with concomitant decrease in total peripheral vascular resistance(58.0+/-3.3 vs. 88.2+/-4.8 dyne sec/cm5 X 105; p<0.01) and splanchnic vascular resistance(2.54+/-0.20 vs. 5.47+/-0.33 dyne sec/cm5 X 105; p<0.01), However, the portal venous resistance was not significantly different in both groups of rats (3.57+/-0.31 vs. 3.03+/-0.38 dyne sec/cm5 X 105; p>0.05). CONCLUSION: The hemodynamic results of this study indicate that hyperdynamic status of systemic and splanchnic circulation was present in chronic portal hypertension and that the primary factor contributing to the persistently elevated portal venous pressure was the markedly increased portal venous inflow.

Arotinolol was administered orally to 31 patients to evaluate is antihypertensive action. After one week of antihypertensive medication, they were given Arotinolol 30mg daily for 4 week. Routine serum chemistries, electrolytes, urinalysis and electrocardiography were studied before and after Arotinolol. Blood pressure measured in sitting, supine and standing position was 175.3+/-5.4/115.7+/-4.0, 168.0+/-5.2/150.0+/-3.8, 154.4+/-8.5/103.4+/-3.2mmHg in control and 143.8+/-2.8/93.3+/-2.8, 144.6+/-5.4/88.1+/-4.3, 139.7+/-4.6/86.8+/-3.4mmHg in Arotinolol treatment group. The differences between both blood pressure were statistically significant(P<0.01). No laboratory test showed significant difference between both period. There were no significant side effects except 2 cases of transient headache and dizziness respectively, and one case of diarrhea. In summary, Arotinolol apears to reduce blood pressure effectively with minimal side effects.

Ulcerative colitis is diffuse inflammatory condition at mucosal lining of the colon & rectum and rare in Korea but there are no pathognomonic features or specific diagnostic tests. However, recently the diagnostic methods for ulcerative colitis are much developed and the incidence of ulcerative colitis is increased in Korea. Therefor, an analysis of 31 cases of ulcerative colitis which was diagnosed and treated in the department of the YeungNam University Hospital from May l983 to April 1991 was reviewed. The results were as following: 1) The sex distribution assumed a ratio of 1 to 2.1 and the age distribution was vqriable but the most prevalent age group was 5th decade(29.0%). 2) The most common clinical manifestations were abdominal pain & bloody diarrhea. 3) As to the extent of disease determined by the barium enema & endoscopy, rectum or rectosigmoid colon was involved in majority of the cases 22.6%, 41.9 (respectively). 4) Significant laboratory findings were elevated ESR, anemia, leukocytosis, hypoalbuminemia. 5) The endoscopic examination was performed in all 31 cases and showed sinificant findings such as hyperemia, mucosai edema, superficial ulceration & mucosal friability. 6) 23 of 26 cases treated by sulfasalazine medication showed improved, and 3 cases were improved by steriod medication and the surgical operation was indicated in 1 case.
