OBJECTIVE: The aim of this study is to present the basic reference data of age and sex specific gait parameters for Korean adults. METHOD: The basic gait parameters were extracted from 70 healthy adults, 38 men and 32women, 21 to 69 years of age using VICON 340 Motion Analyzer. RESULTS: The temporal gait parameters and kinematic parameters of Korean adults were similar to other western reference data. CONCLUSION: Significant sex differences exist in the maximal pelvic tilting, pelvic internal rotation and foot internal rotation and plantar flexion. There is a statistically significant age variability for the hip and knee flexion at stance phase.

Renal angiography has applications in the diagnosis of renal tumor and renovascular hypertension, and provides important anatomical information that can influence the surgical management. Recently the approach to the vascular system for diagnosis by means of Seldinger technique hag been expended to include a variety of therapeutic manner. So, embolization of renal carcinoma is being used with increasing frequency. Radiologic findings associated with presenting symptoms and signs were analysed in 51 cases of renal angiography, during the period of October 1978 to October 1982. The following results were obtained. 1. Male to female ratio was approximately 1:1 and peak incidence was in the sixth decade. 2. The main symptoms and signs of patients were hematuria, flank pain, hypertension and palpable mass, in order of frequency. 3. In 7 hypertensive patients with delayed visualization on the excretory urogram. angiography shows 2 cases of renal artery stenosis, one case of Takayasu's disease and absence of abnormal vasculature in 4 cases. 4. It is suggested most valuable technique for correct diagnosis of renal vascular disease. some of other congenital anomalies, and renal vascular mapping for renal surgery.

The purpose of this epidemiological study is data for incidence of external genitalia anomaly in Korean male infants. 148 cases with external genitalia anomaly were found of total 1920 live male infants (including 132 low birth weights), except 48 still births, born in the hospital of Ewha Woman's University. The following results were obtained. 1. Total incidence of congenital anomaly was 7.5%. Undescended testes (4.5%), hydrocele (2.8%), hypospadia (0.2%) and bifid scrotum (0.1%) were found in order in frequency. 2. Imperfect descent of the testis was found in 88 infants. There were about 32.5% in infant under 2,500gm and about 2.5% in infant over 2,500gm. In 47 boys (30 low birth weights or 64% of the total) the imperfect descent was bilateral, and in 41 (29 low birth weights or 29% of the total) it was unilateral. Of the 41 unilateral cases, 22 were right sided. 54% of the total had been palpable at the external inguinal ring, 37% at the top of the scrotum and 10% had been not palpable. There were no significant differences either between distribution of birth order and incidence of undescended testes. But, their incidence was higher below 19 year-old group and above 35 year-old group in maternal age. Between March and May more boys were born with undescended testis, while their occurrence was considerably lower in November. 3. 90% of hydrocele was found in full term and right side had six times greater than left side. 4. Hypospadia was found in 4 cases of 1920 live male births. The associated anomalies were undescended testes in two cases and imperforate anus in one case. In the 2 cases, it was found at penoscrotal junction and 2 cases were glandular and penile type.

OBJECTIVE: The objective of this study is to evaluate the clinical and angiographic outcomes after primary balloon angioplasty in patients with symptomatic middle cerebral artery (MCA, M1 segment) stenosis refractory to medical therapy. MATERIALS AND METHODS: Eleven patients with intracranial stenosis were treated with primary balloon angioplasty. All patients had MCA stenosis with recurrent transient ischemic attack (TIA). The indication for balloon angioplasty was patients with significant MCA stenosis: 1) age older than 18 years with recurrent or progressive TIA or infarction despite optimal medical therapy, including anti-coagulation, dual anti-platelet, and anti-lipid medication; 2) previous ischemic events or asymptomatic severe stenosis (more than 50%) with poor collateral cerebral circulation, or diminished cerebral perfusion on single photon emission computed tomography before and after administration of the intravenous dosage of acetazolamide. RESULTS: The median age of patients was 53 years (range 44-79). The technical success rate was 100%. Mean pretreatment stenosis degree was 83.63 +/- 9.53% and 29.1 +/- 15.4% before and after angioplasty, respectively. Procedural-related complications occurred in four of 11 patients (36%), but none of the patients had permanent neurological deficit. All patients were available for an average follow-up period of 19.4 +/- 5.1 months. One patient had a stroke in the territory of angioplasty at two months after angioplasty. The stroke free survival rate at 30 days and 12 months was 100% and 91%, respectively. Restenosis over 50% was observed in three of 11 patients (27%); all were asymptomatic. CONCLUSION: Intracranial angioplasty for symptomatic MCA stenosis refractory to medical therapy can be a treatment option to reduce the risk of further TIA or stroke.

This study was designed to investigate the effect of diazepam on the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus. Female rat (Sprague-Dawley) pretreated with oophorectomy and 4 days administration of estrogen. Weighing about 200 g, was sacrificed by cervical dislocation, and the uteruses were isolated. A longitudinal muscle strip was placed in temperature controlled (37℃) muscle chamber containing Locke's solution and myographied isometrically. Diazepam inhibited the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus in a concentration-dependent manner. GABA, muscimol, a GABA A receptor agonist, bicuculline, a competitive GABA A receptor antagonist, picrotoxin, a non competitive GABA A receptor antagonist, baclofen, a GABA B receptor agonist, and delta-aminovaleric acid, a GABA B receptor antagonist, did not affect on the spontaneous and oxytocin induced contraction of the isolated rat uterus. The inhibitory actions of diazepam on the spontaneous and oxytocin induced contraction were not affected by all the GABA receptor agonists and antagonists, but exceptionally potentiated by bicuculline. This potentiation-effect by bicuculline was not antagonized by muscumol. In normal calcium PSS, addition of calcium restored the spontaneous contraction preinhibited by diazepam and recovered the contractile of oxtrocin preinhibited by diazepam. A23187, a calcium inophore, enhanced the restoration of both the spontaneous and oxytocin induced contraction by addition of calcium. In calcium-free PSS, diazepam suppressed the restoration of spontaneous motility by addition of calcium but allowed the recovery of spontaneous motility to a considerable extent. Diazepam could not inhibit some development of contractility by oxytocin in calcium-free PSS, but inhibited the increase in contractility by subsequent addition of calcium. These results suggest that the inhibitory action of diazepam on the rat uterine motility does not depend on or related to GABA receptors and that diazepam inhibits the extracellular calcium influx to suppress the spontaneous and oxytocin induced contractilities.

As the development of the percutaneous renal surgery, Ureteropelvic junction obstruction can be treated with endourologic technique instead of open surgery. Precutaneous endopyelotomy has been used mainly for the treatment of secondary ureteropelvic junction obstruction. But it was also successful for treatment of primary ureteropelvic junction obstruction. Recently, we performed endopyelotomy for 3 cases of ureteropelvic junction obstruction a 39 years-old male who had renal pelvic stones combined with ureteropelvic junction, a 32 years-old male with ureteropelvic junction obstruction and a 23 years-old male who had horseshoe kidney combined with ureteropelvic junction obstruction and good results were obtained.

PURPOSE: This aim of this study is to analyze the dosimetric difference between intensity-modulated radiation therapy (IMRT) using 3 or 5 beams and MSF in the radiotherapy of the left breast. MATERIALS AND METHODS: We performed a comparative analysis of two radiotherapy modalities that can achieve improved dose homogeneity. First is the multistatic fields technique that simultaneously uses both major and minor irradiation fields. The other is IMRT, which employs 3 or 5 beams using a fixed multileaf collimator. We designed treatment plans for 16 early left breast cancer patients who had taken breast conservation surgery and radiotherapy, and analyzed them from a dosimetric standpoint. RESULTS: For the mean values of V95 and dose homogeneity index, no statistically significant difference was observed among the three therapies. Extreme hot spots receiving over 110% of the prescribed dose were not found in any of the three methods. A Tukey test performed on IMRT showed a significantly larger increase in exposure dose to the ipsilateral lung and heart than multistatic fields technique (MSF) in the low-dose area, but in the high-dose area, MSF showed a slight increase. CONCLUSION: In order to improve dose homogeneity, the application of MSF, which can be easily planned and applied more widely, is considered an optimal alternative to IMRT for radiotherapy of early left breast cancer.
