PURPOSE: It is reported that 65% of diabetic male patients over 60 of their age are impotent. However, there is no report concerning the effect of serum glucose control on erectile dysfunction in diabetic patient. This study was performed to evaluate the effects of serum glucose control on erectile dysfunction. MATERIALS AMD METHODS: The development of Diabetes mellitus was defined that the serum glucose level was above 200mg/dL in random test at 25 weeks. We designed the experimental specimen into 3 groups; group I: diabetic OLETF (Otsuka Long Evans Tokushima Fatty) rats without blood sugar control (n=10), group II: diabetic OLETF rats with blood sugar control with 4U insulin subcutaneous injection daily from 26 to 46 weeks (n=10), group III: diabetic OLETF rats with blood sugar control with 10U insulin subcutaneous injection daily from 26 to 46 weeks (n=10). We estimated the collagen content of penile tunica albuginea with the scanning electron microscopy and observed the endothelial layers of corpus cavernosum with the transmission electron microscopy in each group. RESULTS: The serum glucose level was 249 +/- 4.1mg/dL, 234 +/- 2.7mg/dL, 215 +/- 3.0mg/dL respectively in group I, II, III, and decreased in order of group II, III. The differences among groups were statistically significant (p<0.05). The thickness of collagen bundles of penile tunica albuginea was 0.98 +/- 0.1 micrometer, 0.94 +/- 0.3 micrometer, 0.92 +/- 0.1 micrometer respectively in group I, II, III, and decreased in order of group II, III. The differences among groups were statistically significant (p<0.05). The endothelial layers of corpus cavernosum were decreased in II, III. CONCLUSIONS: The serum glucose control in diabetic rats decreases the collagen con tents in penile tunica albuginea and the endothelial layers of corpus cavernosum.

Korean Journal of Urology 1998;39(5):476-479
PURPOSE: Peak urinary flow rate is a widely used parameter in the diagnosis and evaluation of treatment erect of BPH because of its objectiveness and non-in vasiveness. The peak urinary flow rate, however is different with each voided volume in the same patient and tends to decrease even in an asymptomatic man with increasing ages. Therefore we need an adjusted peak urinary flow rate corresponding with the age and voided volume. This adjusted peak urinary flow rate can be used to evaluate the voiding function more easily in the same patient periodically or In the different patient of various voided volume and ages. MATERIALS AND METHODS: Data on age, volume voided and peak urinary flow rate were accumulated from 216 male aged from 10 to 80 who were free of voiding symptoms. All combinations of peak urinary flow rate, age and volume voided were tested for equation of bet fit by the least squares method with search for the equation providing least residual standard deviation with SAS package. RESULTS: When the peak urinary flow rate is defined as a function of age and voided volume, the equation is Q=35.01+0.086A-0.0031A2-1612/V(Q: peak urinary flow rate, A: age, V: voided volume). At the point of population means for volume voided(247.5ml) arid age(35.2) the reference peak urinary flow rate was 27.7m1/sec. Adjusted peak flow rate can be obtained by subtracting the difference between the measured and expected peak flow rate(expected minus measured) from the reference peak flow rate. To make the adjusted peak flow rate obtained easily with measured peak flow rate, age and voided volume nomogram that incorporates the equation has been designed. In our nomogram an adjusted peak flow rate < 19.9 ml/sec or > 1.3 standard deviation below mean should be considered suspicious for obstruction. CONCLUSIONS: Nomogram for adjusted peak flow rate that incorporates the age, voided volume and measured peak flow rate would be satisfactory for clinical use.

5.Sleep Disorders after Stroke.
Brain & Neurorehabilitation 2015;8(2):73-80
Sleep-disordered breathing (SDB) and sleep-wake disorders (SWD) are frequent after stroke. Not only brain damage per se but also the consequences of stroke (immobilization, pain, hypoxia, depression etc) affect sleep wake cycle and breathing control. SDB and SWDs have a negative effect on rehabilitation outcome and quality of life after stroke. A high suspicion may lead to a diagnosis and subsequent treatment of sleep disorders after stroke and contribute to rehabilitation of these patients. This article summarizes the knowledge about the role of SDB and SWD after stroke, reviewing clinical characteristics, clinical outcome after stroke, diagnosis and treatment of various sleep disturbances.

6.Animal Models of Stroke.
Brain & Neurorehabilitation 2011;4(1):1-11
Stroke remains the leading cause of adult disability all over the world. Animal stroke models provide an important neural underlying motor recovery as well as the efficacy of various rehabilitative therapies for enhancing functional recovery. This article reviewed the most commonly used ischemic and hemorrhagic stroke models in rats emphasizing their advantages and disadvantages. In addition, we described the various behavioral tasks for assessing the sensorimotor or the cognitive function after stroke model. Finally, we discused several methodological issues and general considerations for conducting research using rat model of stroke.

In postanesthetic period, infants and children have a risk of hypoxemia due to decreased functional residual capacity(FRC) and increased alveolar-arterial O2 tension gradient(A-a DO2). We measured arterial oxygen saturation(SaO2) with a pulse oximeter in 60 ASA class 1 infants and children. Group 1 was breathing with supplemental oxygen(4L/min) by mask and Group 2 was breathing with room air in recovery room after general anesthesia. SaO2 was measured on arrival in the recovery room, 2,4,6, 8,10,15, and 20 minute after arrival The results were as follows: 1) Postanesthetic SaO2 measured on arrival in the recovery room had decreased significantly(p<0.05) to preanesthetic SaO2 2) SaO2 measured in room air had decreased significantly compared with SaO measured in supplemental oxygen. As a result of the study, it is thought to be safe that supplemental oxygen is administered to patient on transfer and in recovery room.

p27kip1, a cyclin dependent kinase inhibitor, has been recognized as a negative regulator of cell cycle. To investigate the role of p27kip1 on progression of cancer and apoptotic pathway, we analyzed p27kip1 expression using immunohistochemical stain in 40 cases of prostatic adenocarcinoma and apoptotic index by TUNEL method in 30 cases of prostatic adenocarinoma. Both were correlated with Gleason grade and Gleason score. Loss of p27kip1 expression was more frequent in prostatic adenocarcinomas of higher score (Gleason score 7 to 10) (60.7%) than in those of lower score (Gleason score 4 to 6) (33.3%) (p<0.05). The value of mean apoptotic index of carcinoma was 1.13+/-0.26, 1.80+/-0.91, 2.06+/-0.79, and 2.12+/-0.82 in grade 2, 3, 4, and 5, respectively, and was positively correlated with grade of carcinoma (p<0.05). Mean apoptotic index of higher Gleason score (score 7 to 10; 2.05+/-0.63) was also significantly increased than in lower Gleason score (score 4 to 6; 1.34+/-0.39) (p<0.05). Mean apoptotic index in cases with and without p27kip1 expression was 1.92+/-0.86 and 1.89+/-0.81, respectively (p>0.05). These results suggest that loss of p27kip1 expression and increased apoptotic index may be the morphologic markers to predict the behavior of prostatic adenocaricnoma. The role of p27kip1 on apoptotic pathway seems to be meager in this study and needs further study.

10.A Case of Squamous Cell Carcinoma of the Renal Pelvis Associated with Staghorn Calculi.
Korean Journal of Urology 1995;36(1):114-116
Squamous cell carcinoma of the renal pelvis is an uncommon tumor, comprising about 0.5-2% of all primary malignant tumor of the kidney. The patients of this disease usually presented late with extensive local infiltration. In addition, poor response to surgery, radiotherapy and chemotherapy result in a poor prognosis and short survival. We report a patient of squamous cell carcinoma of renal pelvis with staghorn calculi in a 66-year-old woman who had a history of right sided renal colic and palpable abdominal mass.
