The effects of topical sodium-hyaluronan on the stromal and endothelial healing were examined in the repair process of experimental corneal alkali wounds. Corneal alkali wounds were produced in one eye of each rabbit by applying a 5.5 mm round filter paper soaked in 1N NaOH onto the central cornea for 60 seconds. Then the eyes were treated topically with either 1% Na-HA(the treatment group)or a phosphate buffered saline(PBS)(the con-trol group)4 times per day for 3 weeks. Endothelial wound morphometry was performed after alizarin red and trypan blue staining. The stromal healing was assessed by counting polymorphonuclear leukocytes(PMNs)and keratocytes in the central and marginal wounds areas. The stroma treated with Na-HA had less PMNs than that of the control group during the early healing period. The defect area of the endothelium was significantly smaller in the Na-HA treated group than in the control corneas. The present findings indicate that topically applied 1%Na-HA affects stromal and endothelial healing during the early repair process after corneal alkali wounds.

Clavicle medial end fracture is rare, and it has not been studied extensively. Although there is debate regarding its treatment methods, because of the complications of conservative treatment, surgical treatment has been considered more than conservative treatment. This study describes a surgical method using double-plate fixation for treatment of clavicle medial end fractures in which plates were used on each anterior and superior border according to the anatomical structure of the clavicle. In addition, we report operative results of three patients treated by double-plate fixation.

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.

Unilateral nevoid telangiectasia is a rare but clinica.lly distinct dermatosis first deacribed by Zeisler in 1922. It had been also called as linear telangiectasia or unilateral telangiectasia. Wilkin suggested the term unilateral dermatomal superficial telangiectasia, in 1977. There are some reports of congenital unilateral nevoid telangiectasia but it usually occurs in women during the puberty and the third decade. Clinically it is characterized by superficial telangiectatic lesions distributed along the dermatomes uniIaterally and usually on the upper part of the body. It was reported that unilateral nevoid telangiectasia was related with elevated serum estrogen level in the many cases. We present two patients, 23-year and 25-year-old male soldiers, whose leaions were consistent with unilateral nevoid telangiectasia elinically and histopathologically.

25 Patients were received major spinal surgeries at main operating theater of Kangnam General Hospital from May 1990 to December 1990 by using the Haemonetics cell saver which was employed as an intraoperative blood salvage and autologous blood transfuser. The products of washed red blood cells were an average of 1490 cc packed RBC per case. Under the Light Microscopy, Washed RBC disclosed the morphologies of normal RBC size and shape. Fragmented RBCs or cell debris were not found and in one case agglutinated and denaturated RBCs were seen. While 20 patients were received spinal surgery prior to the utilization of cell saver, an average of 7.85 units of banked whole blood was transfused compared with 5.55 units in the cases of using the cell saver (p<0.05). Homologous banked blood utilization during spinal surgery declined more than 30% with the use of the cell saver. There was no evidence of infection, renal and/or hepatic failure related to the use of the cell saver. Haemonetics cell saver appeared to be safe, efficient and more over in some instanes life saving.

The effects of topical sodium-hyaluronan (Na-HA)on the epithelial healing and aqueous compositions were examined in the repair process of experimen-tal corneal alkali wounds.Corneal alkali wounds were produced in one eye of each rabbit by applying a 5.5 mmround filter paper soaked in 1N NaOH onto the central cornea for 60 seconds.Then the eyes were treated topically with either 1%Na-HA (the treatment group)or a phosphate buffered saline (PBS) (the control group)4 times per day.The epithelial healing was assessed using a quantitative method and the changes of the concentration of ascorbic acid and glucose in aqueous were evaluated.The initial epithelial healing rate was similar between 1%Na-HA treated and control groups and the later healing was enhanced in the treated group but statistically insignificant.The concentrations of ascorbic acid and glucose in aqueous humor are not statistically different in the early phase, but ascorbic acid concentration in later healing phase was higher in the treated group when compared with the control group.The present findings in dicate that topical-ly applied 1%Na-HA affects late epithelial healing and ascorbic acid concentration in aqueous humor during the repair process after corneal alkali wounds.
