In femorsl neck fracture, viability of the femoral head depends on the revascularization of the femoral head. The purpose of this study is to observe the effect of early fixation and anatomical reduction by measuring the Tc-99m-MDP uptake ratio of the femoral head in experimental animsls. Femoral neck region of 20 mature rabbits were osteotomized completely and divided into 2 groups ; each group consisted of 10 rsbbits. Group 1 had two Kirschner wire fixation after osteotomy and anatomic reduction. Group 2 had no fixation after osteotomy. The uptake ratio of Tc-99m-MDP of the femoral head in each group were measured st the intervals of 24 hours, 48 hours, 1 week, 2 weeks, 3 weeks, and 4 weeks, respectively. The results obtained were as follows ; 1. In experimental group 1, the mean uptake ratio of the femoral head was 0.72±0.13 at 1 day after operation, increased to a level of 1.44±0.14 at 1 week, increased to a maximal value of 2. 90±0.36 at 3 weeks and decreased to a level of 1.10+0.12 at 4 weeks. 2. In experimental group 2, the mean uptake ratio of the femoral head was 0.70±0.10 at 1 day, 0.64±0.13 at 1 week, decreased to a maximal value of 0.33±0.05 at 3 weeks and 0.47±0.05 at 4 weeks, showing decreased level below 1.0. The results suggest that early anatomicsl reduction and rigid fixation of femoral neck fracture is helpful for revascularization of the femoral head and prevention of non union.

Nd-YAG laser is known as a safe and effective treatment for posterior capsular opacity after cataract surgery. We studied the ocular complications after Nd-YAG laser treatment in uveitis patients. From January 1991 to December 1996, we retrospectively investigated the complications of uveitis in 22 persons(25 eyes) after Nd-YAG laser posterior capsulotomy, and also investigated that of nonuveitis in 563 persons(635 eyes) as a control group. The uveitis cases consisted of six anterior uveitis, eight intermediate uveitis, seven Behcet`s syndromes, three panuveitis, and one posterior uveitis. In the uveitis group, the complications(18 eyes) consisted of three retinal detachments, one giant retinal tear, three glaucoma, two aggravations of uveitis, two vitreous opacities, one retinal emorrhage, one proliferative vitreoretinopathy, one hyphema, and four transient high intraocular pressures(IOP), and in the control group, it consisted of two subluxations of intraocular lens(IOL), three glaucomas, one retinal tear, three transient high IOPs, two vitreous opacities, two retinal hemorrhages, three macular holes, two retinal detachments, and five cystoid macular edemas. From our experience, the incidence of complications after Nd-YAG laser posterior capsulotomy in uveitis was higher than that in nonuveitis. It was also noted that it is necessary to follow up thoroughly the complications after Nd-YAG laser posterior capsulotomy in uveitis patients.

BACKGROUNDS: The inflammatory reaction after cerebral ischemia involving adhesion molecules aggravates neurologic deficit. This study aimed to study the change of plasma level of the adhesion molecules after acute cerebral ischemia. METHODS: Nineteen patients with acute cerebral infarction and ten control subjects without a history of cerebrovascular disease were included in this study. The patient groups were subgrouped into large artery atherosclerosis and small artery occlusion groups according to TOAST classification. Plasma levels of sP-selectin, sE-selectin, sICAM-1 and sVCAM-1 were measured within 24 hours and in 6 to 8 days after acute ischemic infarction. RESULTS: The plasma level of sP-selectin was elevated in acute stroke patients within 24 hours and in 6 to 8 days after stroke onset compared with control group(p<0.05). But plasma levels of sE-selectin, sICAM-1 and sVCAM-1 were not different from those of control group. The plasma level of sP-selectin was significantly elevated in large artery artherosclerosis group compared with control group. CONCLUSION: This study suggest that P-selectin actively involves in inflammatory process after acute ischemic stroke, especially associated with atherosclerosis.

Although most available IOL power calculation formulas perform accurately for eyes of average axial length, they have been shown to be inaccurate for eyes that have unusually short and long axial length. To compare the prediction accuracy of new Hoffer Q with SRK-II formula, we reviewed, retrospectively, a series of 225 ECCE with PCL implantation cases, including 106 Hoffer Q group and 119 SRK-II group, each of which was further divided into subgroups based on axial length. The Hoffer Q formula overestimated the refraction and resulted in more myopic shift and was less accurate than SRK-II in all length eyes, except short length eyes. In short length eyes, both formulas had similar mean error and mean absolute error but Hoffer Q formula was more accurate than the SRK-II in +/- 0.5D prediction proportion.

The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm, 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda. in Korea.
