Running for a long distance in runners with exercise-induced hypertension (EIH) increases high blood pressure (BP) which causes myocardial burden, inducing elevation of cardiac markers. It is assumed to be associated with endothelial dysfunction, but has not been studied so far. The purpose of this study is to exam the responses of anti-inflammatory, inflammatory, and endothelial regulation factors to 100 km ultra-marathon of athletes who have EIH. For this study, we obtain and analysis interleukin-6, tumor necrosis factor-α, interleukin-10 (IL-10), monocyte chemoattractant protein-1, creatine kinase and nitric oxide (NO) from 100 km ultra-marathoners before and right after the 100 km race. There were 40 volunteers who had ever won the 100 km marathon race before more than one time. They had the graded exercise test with measurement of BP for assessing EIH. Among them, eight athletes were categorized to normal control group (NCG) and 10 athletes were assessed by EIH group (EIHG). The graded exercise test with treadmill was performed for the maximal strenuous exercise and BP. EIH was diagnosed as <140/90 mm Hg in normal and ≥210 mm Hg in maximal exercise. Marathoners including EIHG (n=10) and NCG (n=8) participated in the race and blood extracted from them before the race and right after the race. As results, EIHG had lower IL-10 than NCG during resting states and after the 100 km race EIHG had significantly lower NO concentration than NCG. Therefore, the NO in the endothelial is inhibited during strenuous endurance exercise, resulting in vasoconstriction with increasing the BP.

PURPOSE: To elucidate factors affecting the outcome of pyeloplasty, we retrospectively reviewed a consecutive series of children who underwent dismembered pyeloplasty. METHODS: We encountered 37 kidneys in 30 patients with primary UPJ obstruction. Twenty eight were male and 2 were female. Sixteen patients (19 renal units) were younger than 1 year of age. There was a 2.3: 1 predominance of left side. In all 37 renal units, postoperative calyceal dilatations were compared to those of preoperative degrees by excretory urography or ultrasonography. In 20 of 23 unilateral disease, postoperative split renal functions measured by 99mTc MAG-3 or DTPA renal scan were compared to those of preoperative values. Mean follow up was 48.4 months. To assess the degree of improvement of renal function and calyceal dilatation, multivariant analysis was performed by groups according to age, initial presentation, preoperative split renal fuction, laterality and the degree of preoperative calyceal dilatation. RESULTS: In patients younger than 1 year, the most common initial presentation was prenatally detected hydronephrosis (9/16) and in older children, abdominal mass or pain (10/14). In all 20 patients who had renal scan, split renal function was improved in 13 (65.0%) and unchanged in 7 (35.0%) after the surgery. In 9 kidneys with impaired preoperative split renal function (less than 35%), renal function was improved greater than 5% in 8 (88.9%) after the surgery. in the other 11 renal units, the function was greater than 35% before and after the surgery. The improvement of calyceal dilatation was noticed in 33 (89.2%) of the renal units and more significant in groups of children who had high grade (IV,V) hydronephrosis with preoperative renal function of greater than 35%. The degree of functional improvement was better in groups of patients whose age were under 12 months and also who had impaired renal function with mild to moderate calyceal dilatation. The half time clearance was well correlated to the degree of calyceal dilatation. No one underwent repeated operation. CONCLUSIONS: Dismembered pyeloplasty is safe and highly successful procedure. The greatest potential recovery of renal function was noticed in patients with decreased renal function but mild to moderate hydronephrosis. And the resolution of calyceal dilatation was most likely in patients with severe hydronephrosis but well preserved renal function.

PURPOSE: To evaluate the clinical usefulness of PAP in staging and monitoring of patient with prostate cancer, we performed a comparative study with PSA, retrospectively. METHODS: We evaluated 72 patients with prostate cancer. Of these patients 11 had stage A, 6 stage B, 10 stage C, 5 stage D1 and 40 stage D2 prostate cancer. Serum PAP level was measured in all 72 patients and serum PSA level was measured concomitantly in 42 patients. RESULTS: The mean initial PAP value was 13.40+/- 7.00 U/L. But only 40 (55.6%) had elevated PAP value above 1.5U/L at presentation. Of 55 advanced cases (stage C, D), 39 (76.9%) had elevated PAP values. Of the 42 patients, who underwent longitudinal PSA assessment, the mean initial PSA value was 178.0 +/- 33.3 ng/ml. Forty (95.2%) had elevated PSA value above 4 ng/ml at presentation. Of 41 advanced cases (stage C, D1, D2), 33 (80.5%) exceeded 50 ng/ml. None of the patient had elevated PAP value with normal PSA value at presentation. Among 42 patients, who had followed with longitudinal serum PSA and PAP, progression of the disease to the bone, lung, and rectum occurred in 26 patients; in all PSA was the first indicator of progression and in none of them PAP anticipated PSA elevation. CONCLUSIONS: Although PAP value usually reflects advanced prostate cancer (70.9%), serum PSA also reflects it (80.5%). Serum PSA monitoring is superior to serum PAP monitoring in predicting disease progression. The use of PSA and PAP jointly to stage and monitor prostate cancer did not appear to enhance the clinical utility over that of PSA alone.

A clinical and histopathological study was performed on ninety-four patients with nephrotic syndrome (91 idiopathic and 3 secondary) who were admitted to Department of Internal Medicine, Yeungnam University Hospital during the period of nine years, from January 1985 to May 1994. The results were as following. 1. the ratio of male to female was 1.76:1. In young age group, minimal change was the most predominant type. In old age group, membranous glomerulonephritis and focal glomerulosclerosis were predominant types. 2.- The primary nephrotic syndromes were 96.8% and secondary nephrotic syndromes were 3.2%. Histopathologic findings of 94 renal biopsy tissue were classified into minimal change (43.6%) mesangial proliferative glomerulonephritis (29.8%), membranous glomerulonephritis (12.8%), Typel membranous proliferative glomerulonephritis (4.3%), focal glomerulosclerosis (3.2%) .and others (6.4%). 3. The response of eighty-six patients treated with steroid showed complete remission in 51.2%, partial remission in 20.9%, steroid dependent in 2.3%, and no effect in 25.6% of cases respectively. The response to steroid therapy was most effective in the patients with minimal change lesion. 4. In the patient with membranous proliferative glomerulonephlitis, long-term angiotensin converting enzyme inhibitor treatment showed less deterioration of renal function.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

PURPOSES: Transurethral resection of the prostate (TURP) for symptomatic benign prostate hyperplasia (BPH) remains a gold standard for surgical treatment, but significant morbidities are associated with the procedure. Transurethral electro-vaporization of prostate (TVP) using a grooved ball electrode, a modification of standard TURP, was tried on bladder outlet obstruction in an attempt to reduce the morbidity rate of TURP. We compared between the TVP and standard TURP to estimate the efficacy and safety. MATERIALS AND METHODS: A comparative trial of 44 patients with symptomatic BPH from May 1995 to December 1995 was performed. Of the patients 20 were received operation with TVP (Group I) and 24 were received with standard TURP (Group II). Patients were assessed at baseline for both safety and efficacy and in follow-up at 1 and 3 months. Efficacy parameters evaluated included American Urological Association (AUA) symptom score, peak urine flow (Qmax) and postvoid residual urine (ml). Safety parameters evaluated included incidence of side effects, operative time (in minutes), postoperative catheterization time, change in hematocrit and serum sodium. RESULTS: The mean age of each group was 63.7+-6.4 years (Group I) and 68.8+-7.6 years (Group II), the prostate size was 32.4+-3.4g and 34.5+-6.5g. The mean operation time was shorter in Group I (56+-11min) than Group II (85+-34min), (P<0.05). The change of Hematocrit(ml/dl) was lower in group I (from 41.1+-5.0 to 39.5+-4.2) than group II (from 39.6+-4.4 to 35.2+-5.5), (P<0.05). The mean catheterization time was 3.3+-1.3 days and 4.8+-1.7 days, (P<0.05). change of maximal flow rate, post-void residual volume and AUA symptom score was not significantly different between each group. The incidence of postoperative complications were not significantly different between each group. CONCLUSIONS: Although the TURP is the gold standard for the treatment of symptomatic BPH with high success rate, but significant morbidities rate are associated with this procedure. So, TVP is new and potentially useful modification of TURP. In this preliminary study, there has been significant clinical improvement maintained with minimal morbidity. This early clinical experience highlights several potential advantages of TVP, including rapid convalescence time, short hospital day, and minimal blood loss. So, TVP is one of the various therapeutic alternatives for BPH lowering the morbidity rate of standard TURP.

Steroid cell tumor of ovary, first described as lipid cell tumor, is rare lesions composed entirely of cells resembling typical steroid hormone - secreting cells, that is lutein cells, Leydig cells, and adrenal cortical cells. Steroid cell tumors oftcn secret androgen and manifest themselves with symptoms of virilization. Other presentations include abdominal swelling or pain, menstrual dysfunction, postmenopausal bleeding, or rarely ascites. We experienced a case of right ovarian steroid cell tumor, not otherwise specified(NOS), manifested hirsuitism and amenorrhea in 49 - year - old patient. The tumor was about 5 cm in size, and associated with huge ascites (l3,000 ml), both pleural effusion, and elevated serum CA 125. We present a case of Meigs syndrome associated with benign ovarian steroid cell tumor with a brief review of the literature.
