Extensor pollicis longus tendon rupture is well known as a complication of fracture of the distal radius. There is a higher risk that the tendon of extensor pollicis longus will rupture in undisplaced distal radius fracture than in those which are displaced. We have experienced three cases of rupture of the extensor pollicis longus tendon after undisplaced distal radius fracture. Those were treated by tendon graft and tendon transfers. The results were satisfactory without complications. The patients with undisplaced distal radius fracture should be careful concerned about possibility of rupture of extensar pollicis tendon.

BACKGROUND: A definition of granuloma is a focal chronic inflammatory response to tissue injury evolved by a poorly soluble substwice characterized by the accumulation and proliferation of the mono-nuclear histiocytic cells. The accuracy with which rnononuclear cells may be identified in skir. is much improved by the use of both heteroantisera and monoclonal antibodies directed against selected cellular antigens, OBJECTIVE: Our purpose was to examine the staining patterns of anti-lysozyme, anti-a-1-antitrypsin, anti-S-100 protein antibodies, and MAC-387 monoclonal anibody in granulomatous skin diseases. METHOD: We performed imminoperoxidase staining(the labelled str prvidin-biotin peroxidase complex method on the formalin-fixed, paraffin-embedded tissue specimens of granulomatous skin diseases. RESULTS: S-100 protein positive dendritic cells were demonstrated in the granulomatous infiltrates as scattered pattern and MAC-387 positive cells were predominantly found in the center of granulomas, The staining pattern and percentage of positively stained cells of a--antitrypsin were similar to those of lysozyme. A1Pha-1-antitrypsin and lysozyme positive cells w re present in the center as well as lymphohistiocytic infiltrates of granulomas. CONCLUSION: These data sugget that histiocytes are composed of heter igeneous groups of cells such as the mononuclear-phagocyte system and dendritic cell system.

We evaluated an effect of the distance between the incision line and corneal limbus on surgically induced astigmatism in sutureless cataract surgery with scleral tunnel incision. We made a 6mm scleral tunnel incision 1.0mm from the limbus (Group 1, 24 eyes) and 2.5mm from the limbus (Group 2, 30 eyes) and implanted polymethylmethacrylate (PMMA) intraocular lenses with a round optic of 6mm following phacoemulsification. We employed the Jaffe method and Cravy method of vector analysis to evaluate the change of Surgically induced astigmatism. The mean surgically induced astigmatism using Jaffe method was 1.24 D and 0.98 D one day after surgery in Group 1 and 2, respectively. The difference between them was statistically significant(p<0.01) and became insignificant(p>0.05) after postoperative one week. In the superior incision cases, the difference using Cravy method was not statistically significant for whole followup period. In the temporal incision cases, the surgically induced astigmatism was 0.39 D and 0.02 D one day after surgery in Group 1 and 2, respectively. The difference was statistically significant(p<0.05) and became statistically insignificant(p>0.05) after postoperative one week. In this study it was found that a distance of incision line from corneal limbus longer than 1 mm was not an important factor in influencing the surgically induced astigmatism one week after sutureless cataract surgery using a watertight scleral tunnel incision.

We analyzed postoperative astigmatic changes according to the location of incision in 129 eyes that sutureless cataract surgeries were performed. We followed up the astigmatic changes until six months postoperatively, and compared the results of two groups of which the one is the preoperative against-the-rule astigmatic cases with superior incisions and temporal incisions, the other is the preoperative oblique astigmatic cases with superior incisions and superotemporal incisions. In the preoperative against-the-rule astigmatic cases, postoperative astigmatic changes were shifted toward against-the-rule astigmatism(0.23 diopters) in superior incisions and toward with-the-rule astigmatism(0.20 diopters) in temporal incisions until 6 months following surgery(p<0.01). Surgically induced astigmatisms were also less for in temporal incisions than superior incisions(p<0.01) and corneal astigmatisms were stabilized after two weeks postoperatively in both groups(p<0.05). In the preoperative oblique astigmatic cases, postoperative astigmatic changes were shifted toward against-the-rule astigmatism(0.63 diopters) in superior incisions and also toward against-the-rule astigmatism(0.46 diopters) in superotemporal incisions until 6 months following surgery(p>0.05). Surgically induced astigmatisms were less in superotemporal incisions than superior incisions (p<0.01) and corneal astigmatisms were stabilized after one month postoperatively in both groups(p<0.05). These results demonstrated that surgically induced astigmatisms were decreased by the incision at steep axis, and in the cases of preoperative againstthe rule astigmatism, the preexisting astigmatisms were decreased by the temporal incisions.

The rabbit cornea was studied in vitro in modified Ussing chambers to determine the effects of ion transport inhibitors and hydrogen peroxide(H2O2) on ion transport through the cornea by measuring the bioelectric properties. Apical(tear side, T side) addition of furosemide, bumetanide and SITS were ineffective on resting Isc(short circuit current). Apical addition of 1.0mM amiloride(Na+/H+ antiport inhibitor) and NPAA(Cl- channel blocker) markedly reduced the resting Isc, but basolateral(stromal side, S side) addition of amiloride was ineffective. The site of action of these agents was the apical membrane. H2O2, an oxygen free radical, markedly increased the lsc when was added to the T side, but S side addition of the H2O2 was ineffective. To determine the degree of cellular catalase participation in protection against H2O2 induced injury the cornea was pretreated with ATAZ for 30 min prior to H2O2 action. The increase of lsc by H2O2 was markedly potentiated after pretreatment with ATAZ on T side compared to that of S side addition. This result indicates that the corneal endothelial H2O2 may be largely degraded by catalase. When H2O2 was added to the T side, Isc was raised by increased ion transport. All ion transport inhibitors that were used inhibited the H2O2 effect on Isc. Moreover, amiloride and NPAA markedly inhibited induced lsc by H2O2. These results suggest that H2O2 stimulates the corneal epithelial ion transport and that its site of action is apical membrane Na+/H+ antiport system and CI- channel system.

7.Apparent Accommodation in Posterior Chamber IOL Implanted Eyes.
Journal of the Korean Ophthalmological Society 1992;33(12):1162-1167
In order to evaluate the cause of apparent accommodation in pseudophakia, we performed ECCE and implanted biconvex, monofocal I0L in the bag in 24 patients(32 eyes) and followed up for more than 2 months. We measured apparent accommodation, corneal astigmatism and near visual acuity. And we also measured apparent accommodation and the changes of anterior chamber depth according to the movement of I0L and apparent accommodation according to the changes of pupil diameter in normal state before drug instillation and after instillation of either 10% phenylephrine or 2% pilocarpine. The results were as follows: 1. The mean apparent accommodation was 1.36 +/- 0.52 diopters. 2. There was negative correlation between corneal astigmatism and apparent accommodation and between cornel astigmatism and near visual acuity. 3. There was negative correlation between anterior chamber depth and apparent accommodation measured in normal state before drug instillation. And also there was negative correlation between the changes of anterior chamber depth and the changes of apparent accommodation measured after instillation of either 10% phenylephrine or 2% pilocarpine. 4. There was positive correlation between reciprocal changes of pupil diameter and apparent accommodation. So we conclude that the apparent accommodation is seemed! to be a resultant changes according to the changes of the pupil diameter.

Journal of the Korean Ophthalmological Society 1995;36(4):589-597
We performed an analysis of corneal astigmatism of 123 eyes with suturing(sutured group) and 56 eyes without suturing(sutureless group) after phacoemulsification and PCL implantation through 7.0 mm straight incision wound 2.0-2.5 mm from superior limbus by use of algebraic and vector methods for two years following surgery. In both groups, the amount and axis of astigmatism were continued to change for 2years(p>0.05). The amount of astigmatisms in sutureless group was less than in sutured group until 2 months postoperatively(p<0.01), no significant difference from 3 months to 6 months postoperatively(p>0.05). Astigmatic changes in sutureless group were stable and had lower against-the-rule shift than the sutured group after 6 months postoperatively(p<0.01). Surgically induced astigmatism was stabilized after 1 month postoperatively in sutured group and after 2 weeks psotoperatively in suture less group(p<0.01), and it was lower in suture less group than sutured group during the two years postoperatively.(p<0.01).

The appendiceal mucocele is a rare disease and very difficult to get the diagnosis preoperatively because of the rartity of classical symptoms. With progress in diagnostic procedures such as colonofiberscopy, preoperative diagnosis of appendiceal mucocele has become possible. We experienced a case of appendiceal mucocele in 50 years old male who was admitted due to vague RLQ discomfort, and was diagnosed by colonofiberscopy and surgical specimen obtained by right hemicolectomy. So we present this case with a review of literatures.
