Pityriasis rotunda is an uncommon chronic dermatosis characterized by multiple, round or oval, hyperpigmented or hypopigmented patches that have a fine scale on the trunk and extremities. Most of the cases reported predominantly occurred in Oriental and black patients in association with internal disease. However, in Caucasians it has been documented in healthy persons usually as a familial tendency. We report a case of pityriasis rotunda which showed familial occurrence and had no underlying disease.

Soft tissue related complications are quite frequent in limb lengthening. Muscle fibers may proliferate or regenerate after stretching injury over 10-20% of their original length. However, the cells which are engaged in this phenomenon are not confirmed yet. We chased the S-phase cells (phase for DNA replication) in the posterior leg muscle during limb lengthening by immunohistochemical technique. We lengthened the tibiae of fifteen New Zealand white rabbits. We divided them into three groups and each group is consisted of five rabbits. In group 1, we lengthened the left tibiae by 10% of their original length, in Group 2, 20%, and in group, 3, 25%, respectively, At the end of lengthening posterior muscles of lengthened left side and of controlled right side were fixed and processed for Immunohistochemical staining which could detect the incorporation of bromodeoxyuridine(BDU). Labelling index(LI:% of positively stained S-phase nuclei) of group 1 was zero. LI of groups for more than 20% lengthening (sum of group 2 and 3) was statistically significant. In conclusion, nuclei around or within the muscle tissue are in S-phase during limb lengthening which means proliferation of the muscle fivers or of the certain cells that abut muscle fibers.

The midface are bounded by a line connecting the two zygomaticofrontal suture, passing through the frontomaxillary and frontonasal suture, and limited below by the occlusal plane of maxillary teeth. Midface fractures include fractures affecting the maxilla, the zygoma, and the nasoorbital ethmoid complex. Midface fractures can be classified as LeFort 1, II, III fractures, sygomaticomaxillary complex fractures, zygomatic arch frationctures, or nasoorbital ethmoid fractures. These injuries may be isolated or occur in combine. And sort tissue injuries to the facial structures are commonly encountered in the treatment of midface fractured patient. Soft tissue wounds may be limited to the superficial structures, but more serious injuries may extend to involve anatomic structures such as the sensory and motor nerves of the face; the parotid, or nasolacrimal glands or ducts ; or the dentoalveolar structures. Especially, these fractures are combined with the orbit, brain injuries and skull base fractures. This is to report the incidence, causes, criteria, complication and treatments of patients who visited our department for midface fracture, for last 10 years.

Average anteversion of the femur is 15.3 degree. Ultrasound, computerized tomogram, and three dimensional reconstruction from CT or MRI have been used for more accurate measurement of the anteversion. There are two methods in measuing anteversion angle from CT scan:one is by drawing a mid line through long axis of the femoral neck (conventional method). Another is by drawing a line from the center of the head to that of the neck at the base of the trochanter using several cut slices (Murphy’s method). We compared these methods with fluoroscopic measurement of the Anteversion. We traced the change of the anteversion before and after closed femoral intramedullary (IMO) nailing to evaluate the origin of malrotation of the femur. 1. Normal anteversion angles were measured in 15 cases. Average anteversion angle was 6.9 degrees by conventional method, 12.3 degrees by Murphy’s method, and 12.2 degrees by fluoroscope. 2. Anteversion angles were measured after IM nailing in 18 cases. Average was 17 degrees by Murphy’s method and 15.2 degrees by fluoroscope. Mean of difference between these two methods sea 6.3 degrees. That was 1.7 degrees in normal side. 3. Change of the anteversion angle between before and after IM nailing was measured in 17 cases by fluoroscope. Average anteversion angle before the operation was 11.9 degrees and it was change to 15.8 degrees after operation. Mean of these change was 7.1 degrees. 4. Pereperative traction provides important information on change of anteversion. Reduction excessive flexion of proximal fragment was a origin of change of anteversion during nailing procedure. Conclusion : Malrotation of the femur after IM nailing must be keep in mind and it may be preventable by fluoroscopic control of the rotation in nailing procedure.

BACKGROUND: Recently, Doppler echocardiography has been widely used to evaluate left ventricular(LV) diastolic filling. However, There are only limited date about the influence of LV systolic function on the pattern of left ventricular diastolic filling. METHODS: To evaluate the changes of Doppler echocardiographic parameters of left ventricular filling induced by variations in left ventricular systolic function in dilated cardiomyopathy(DC) with heart failure(HF), 25 patients(M : F=14 : 11) with DC and HF, and 21 age-matched normal subjects(M : F=13 : 8) were examined by ECG, phonocardiography and echocardiography. From the Doppler recording, A2D(time from second heart sound to the onset of early diastolic mitral flow), peak velocity at early diastole(E) and late diastole(A), ratio of E to A velocity(E/A) and flow velocity integral(FVI) were measured. RESULTS: In 22 patients with DC and HF without mitral regurgitation(MR), A2D was significantly prolonged(119.5+/-12.7 vs 92.4+/-14.1msec, p<0.01), and early diastolic peak velocity and E/A velocity ratio were decreased as compared with the normal subjects(E=0.39+/-0.08 vs 0.57+/-0.12m/sec, p<0.01, E/A : 0.87+/-0.19 vs 1.33+/-0.19 vs 1.33+/-0.18, p<0.05). There were significant correlations between A2D and FVI(r=+0.73, p<0.01), and between E/A velocity ratio and FVI(r=-0.78, p<0.01). However, in 3 patients with MR, A2D(88.7+/-12.1msec), E(0.56+/-0.05m/sec), and E/A(1.32+/-0.12) were similar to those in normal subjects, despite of decreased FVI(12.0+/-0.9cm). CONCLUSIONS: These data show that a change of left ventricular systolic function in patients without MR may influence a diastolic filling pattern of left ventricle but not in patient with MR, and suggest that MR masks left ventricular distolic filling abnormalities.

Glutathione S-Tanaferase (GST) is tripeptide, which plays a central role in the detoxification of electrophilic xenobioticas, including cytotoxic drugs and carcinogens, by conjugation with redueed glutathione. There are four major claases af human GST : pi, alpha, mu and rnicrosomal, They are propoaed as a marker for human and experimental neoplasia iincluding liver, kidney, lung,colon, uterine cervix, etc. Expression of pi, alphn, mu form of GST in control (15 cases), CIN (14 cases), invasive carcinoma (28 cases) of human uterine cervix was investigated immunohistochemically. They were selected fram September, 1992, to,June, 1992, in the department of Obstetrics and Gynecology, Yonsei university College of medicine. In nucleus, the expresaion of GST pi was increased statistically significant in case of CIN and invasive Ca. of Cx. compared to control(p=0.018, p=0.002). But expression of GST alpha, mu has no significant difference in each case. In cytoplasms, the expvession of GST pi was increased statistically significani, in case of CIN and invasive Ca. of Cx. (p=0.001, p<0.001). But expreasion of GST alpha, mu has no significant differenrce in each case. There was no statistically significant diHerence in expression of GST isoenzymes oC each nucleua and cytoplasm according to stage and cell type in Ca. oC Cx. The further evaluation of survival and expression of GST pi in Ca. of Cx. in order to establish new prognostic factor in Ca. of Cx.

10.A Statistical Study of Recurrent Urolithiasis Preliminary Report.
Korean Journal of Urology 1978;19(6):537-543
A statistical analysis was made on patient of recurrent urinary stones during the period from May 1972 to April 1977 in the Department of Urology of Han Yang University Hospital and the results were obtained as following: 1. Among the 894 patient of in-patient, 290 patient were urinary stone patients (32.8 %). 2. The recurrent patients were 11 (20%), with the follow-up period from 1 year to 10 years, in whom follow-up was possible. 3. The most common age group of recurrent stones were from 20 to 40 years old ( 72.8%). 4. The mean period from primary stone to recurrent stone was 4.4 years. 5. Among the recurrent patient, 2 were prolonged recumbency patients and one had duplicated ureter. Others were idiopathic recurrent stones. 6. If the primary stone was removed by operation, recurrent stone was some hard to be passed spontaneously.
