In children, the supracondylar fractures of the humerus are common in elbow region, and often associated with various complications and problems in treatment (ie,Volkmann's ischemic contracture, cubitus valgus or varus deformity, rotational deformity). The results of reduction can be measured by Baumann's angle, carrying angle, trochlea-capitellum angle, and displacement of distal radial styloid process on radiological study. So we have made experiments on the process which various three dimensional displacements reflected into two dimensional Baumann's angle and humerocapitellar angle. And we investigated the process of rotation, through various radiological studies by means of molded models of humerus. The results were as follows:l. In experiments, AP & lateral X-ray studies showed no change in rotation of proximal segment of fracture with fixed distal segment of fracture. 2. On the other hand, AP & lateral X-ray showed significant change, in rotation of proximal fracture segment with distal segment of fracture. 3. Supracondylar rotation angle(S.R.A.)depicted as the ratio of the length of proximal fracture width minus that of the distal fracture width in lateral view, to the length of distal fracture width in AP view minus that of the distal fracture width in lateral view. 4. According to the modified Mitchell result, S.R.A. to the result of treatment was average 7.6 degree in excellent group, 15.2 degree in good group and 29.3 degree in unsatisfactory group.

PURPOSE: Information has been limited on the genetic control of germ cell apoptosis and its role in the pathogenesis of male infertility. The object of this study was to investigate the effects of c-kit gene expression and apoptosis on human spermatogenesis. MATERIALS AND METHODS: Testicular specimens were obtained from 90 infertile males with nonobstructive azoospermia(NOA) due to primary testicular failure and from 9 healthy volunteers. The specimens of infertile men were divided into 4 groups according to hitopathologic findings: Sertoli cell only(SCO) syndrome(A), maturation arrest(B), hypospermatogenesis(C) and disorganization with sloughing(D). C-kit gene expression and apoptosis were detected with immunohistochemical stain. RESULTS: The frequency of c-kit expression was lower(p<0.05) and that of apoptosis was higher(p<0.01) in infertility groups B, C, and D compared to that of the control group. A significant inverse correlation was observed in the c-kit gene expression and apoptosis in groups B, C and D(p<0.05). A similar relationship was also observed in the Sertoli cells in group D and the control group. CONCLUSIONS: With the result, we suggest that variation in c-kit gene expression and apoptosis are associated with abnormal spermatogenesis and play a role in the pathophysiology of male infertility.

PURPOSE: To evaluate the expression of the Na(+)-K(+)-2Cl(-)-cotransporter 2 (NKCC2) in the ischemic rat retina. METHODS: Retinal ischemia was induced by pressures 90 to 120 mmHg, above systemic systolic pressure. Immunohistochemistry and western blot analysis were performed. RESULTS: NKCC2 is expressed in the normal retina and its expression is increased by ischemia caused by intraocular pressure elevation. NKCC2 immunoreactivity was observed mainly in axon bundles of ganglion cells and horizontal cell processes in the retina. NKCC2 expression continuously increased with a peak value 3 days (to 415% of normal levels) after ischemic injury, and then gradually decreased to 314% of controls until 2 weeks post injury. The mean density of NKCC2-labeled ganglion cells per mm2 changed from 1,255 +/- 109 in normal retinas to 391 +/- 49 and 185 +/- 37 at 3 days and 2 weeks after ischemia, respectively (p < 0.05), implying cell death of ganglion cells labeled with NKCC2. CONCLUSIONS: Taken together, these results suggest that NKCC2, which is expressed in retinal ganglion and horizontal cells, may contribute to cell death by ischemic injury in the retina, although the molecular mechanisms involved remain to be clarified.

In order to observe the arrhythmia which occured in early convalescent phase of acute myocardial infarction, a 24 hour ambulartory ECG monitiring was performed in 15 patients who is admitted at dept of Int Medicine, Ewha Womans University hospital from Aug. 1985 to Sept. 1986. during 7.5+/-3.4 days after admission. In all cases one or more of the following arrhythmias were observed;atrial premature beat, ventricular premature beat(VPB), transient paroxysmal ventricular thchycardia, atrial fibrillation, sinus arrest and junctional beat. Of 15 cases, 11(77.3%) had VPB's:Simple VPB's in 4 cases(26.7%) and complex VPB's(6.52+/-2.52)(P<0.05). But there were no difference of premature and abberancy index between complex VPB's and simple VPB's(P>0.1). In addition, we compaired the arrhythmias in CCU with those of early convalescent phase of acute myocardial infarction. But there was no correlation between them.
