Male genital tract inflammatory conditions may be associated with unexplained infertility. The presence of cytokine such as tumor necrosis factor-alpha (TNF-alpha) was reported in the semen of infertile men. However, the effect of these cytokines on human sperm function is still unclear. The purpose of this study was to investigate the in-vitro effects of TNF-alpha on human sperm motility with computer assisted sperm analysis. Washed sperm from 16 normal men were incubated without and with TNF-alpha(0.1, 10, 1000 ng/ml). The changes of parameters of sperm motility were recorded at different time intervals (0, 5, 24 hour). There was no significant change of parameters of sperm motility in the incubation with TNF-alpha. It is suggested that TNF-alpha alone does not interfere with the sperm motility and more studies are needed.

Cheilitis granulomatosa is one of the rare dermatoses which is characterized by a sudden onset and a progressive course termination in chronic enlargement of the lips Usually, enlargement of lip is the only symtom without ulceration, fissurign or scaling. It may be considered a part of the Melkersson-Rosenthal syndrome and the etiology is still unknown. A 35 year old female with the clinlcal symptoms of cheilitis granulomatosa is presented; the diagnosis was confirmed by histopathologic study.

OBJECTIVES: Some emotional components, such as self-esteem, depression and anxiety, have been reported to be associated with paranoia in non-clinical population and schizophrenia patients. The aim of this study was to investigate the correlation between self-esteem and paranoia in healthy controls, in ultra-high risk for psychosis and schizophrenia patients. METHODS: 34 subjects with recent onset schizophrenia, 36 subjects with ultra-high risk for psychosis, and 44 healthy volunteers participated in this study. A detailed assessment was made of the paranoia, self-esteem, depression, and anxiety. RESULTS: In all three groups, there were a negative correlation between paranoia and self-esteem, and positive correlations between paranoia and depression and anxiety. In healthy control, lower self-esteem showed a trend to predict higher paranoia, and in ultra-high risk for psychosis, this trend tern on statistically significant level, and in recent onset schizophrenia group, this correlation was disappeared. CONCLUSION: The individual who have lower self-esteem showed higher paranoia tendency under delusional level, but after formation of persecutory delusion, the tendency was disappeared. This result supports the hypothesis that persecutory delusions are a defense against negative affective process.

BACKGROUND: Oxygen free radicals have been implicated as a cause of deleterious effects in the setting of coronary reperfusion, and they are believed to be generated by the xanthine oxidase system, from activated neutrophiles and from mitochondria. We evaluate the contribution of mitochondria to the production of oxygen free radicals and clarify the mechanism of cellular damage in ischemic reperfused hearts. METHODS: Mitochondria isolated from the ischemic rabbit hearts were incubated in the reaction conditions with different oxygen tensions. Generation of superoxide anion and activities of defensive enzymes aginst oxidative stress were mesured. RESULTS: Superoxide anion genertion by mitochondria incubated in 21% oxygen condition were 0.54+/-0.09 and 0.27+/-0.04(O2./min/mg protein) in ischemic mitochondria and in control respectively(P<0.05). Activites of defensive enzymes against oxidative stress, superoxide dismutase and glutathione peroxidase, were significantly reduced in mitochondria isolated from either ischemic or reperfused hearts. With the lapse of respiration in 21% oxygen condition, ADP-stimulated state 3 oxygen consumption(306.4+/-31.5 vs 214.4+/-11.4n atoms O/min/mg protein) at 30 minutes, P : O ratio and phosphorylation rate were significantly decreased in ischemic mitochondria. CONCLUSION: Elevation of oxygen free radical generation as well as the reduction of defensive enzyme activities in ischemic reperfused mitochondria are injurious to mitochondrial respiratory function. It may contribute to the mechanism of cellular damage in ischemic reperfused hearts.

PURPOSE: Glutamate and aspartate are the excitatory amino acid neurotransmitters and NMDA (N-methyl-D-aspartate) is one of their major receptors. NMDA agonist may sti mulate serotonergic nervous system that inhibit the penile erection as well as induce the penile erection. We investigate the effects of NMDA agonist on serotonin release from hippocampus. MATERIALS AND METHODS: The slices of hippocampus were incubated in a buffer con taining 0.1mM [(3)H]5-hydroxytryptamine (5-HT) for uptake in the male rat. The release of 5-HT into the buffer during each 10 minutes period was measured and the radio activities in each buffer and the tissue were counted. After 50 min from the initiation, NMDA agonist were administered at 6th and 7th 10 min period respectively. The changes of 5-HT release were expressed as percent values compared to the 5th 10 min period. Tetrodotoxin was used to determine the possible involvement of interneuron on the action of these neurotransmitters. RESULTS: A steady release of 5-HT was observed up to 100 minutes after the rapid release during the first 40 minutes. Treatment of tetrodotoxin (10(-6)M) did not change the spontaneous release of 5-HT. The 5-HT released during 10 and 20 minutes of NMDA agonist (10(-4M)) treatment significantly higher than those of control group. The increase of 5-HT release by NMDA agonist was blocked by pretreatment with tetro dotoxin. The release of 5-HT was increased by NMDA agonist and this response was blocked by tetrodotoxin. CONCLUSIONS: NMDA agonist increases the release of 5-HT through the activation of the interneurons and these results suggest that NMDA agonist may stimulate the serotonergic nervous system that inhibit the penile erection as well as inducing the penile erection.

BACKGROUND: In congenital heart disease, the lung perfusion through stenosed pulmonary artery is usually decreased. And this decrement of lung perfusion also occurs with diaphragmatic palsy after the operation of congenital heart disease. It is difficult to delineate the amount of lung perfusion in case of combination of pulmonary artery stenosis and diaphragmatic palsy. We examined the change of lung perfusion after the induction of diaphragmatic palsy in rabbits. METHODS: We dissected left phrenic nerves in 20 rabbits to induce left diaphragmatic palsy. The lung perfusion scan was performed with 99mTc-MAA and the movement of diaphragm was examined with fluoroscopy. They were performed as baseline data and on 3rd and 10th day postoperatively. The amount of left lung pefusion before and after diaphragmatic palsy was compared and analysed in 12 rabbits which definitely had diaphragmatic palsy. RESULTS: Weight of the rabbits was 1.65+/-0.26 kg. Left lung perfusion percent was 45.93+/-6.42% before operation and these were 32.48+/-6.09% and 37.62+/-3.39% on the 3rd and 10th postoperative day, respectively. Left lung perfusion was significantly decreased just after diaphragmatic palsy but it was not changed thereafter. The decrement of lung perfusion was not affected by the body weight. The decreased amount of left lung perfusion was reciprocally correlated with the body weight of the rabbits on the postoperative 3rd day but not 10th day. CONCLUSION: Left lung perfusion percent of the rabbits was decreased 7% with the induction of diaphragmatic palsy and the decreased amount was reciprocally correlated with the body weight just after the diaphragmatic palsy was induced.

BACKGROUND/AIMS: Ultrasonography is the easiest, fastest procedure for the diagnosis of choledocholithiasis, but the diagnostic failure are mostly because of the intrapancreatic level of this condition and the absence of bile duct dillatation. Endoscopic ultrasonography is a promising procedure for the diagnosis of extrahepatic cholestasis due to noninvasiveness and accuracy in the digestive gas interposition. The aim of this study was to prospectively compare the diagnostic accuracy of endoscopie ultrasonography with abdominal ultrasonography and endoscopic retrograde cholangiography in 66 patients with suspected choledocholithiasis. METHODS: All of the patients had abdominal ultrasonography, endoscopic ultrasonography ~and endoscopie retrograde cholangiography within 72 hours and final diagnosis was determined by endoseopic retrograde cholangiography with sphincterotomy. RESULTS: (l) Choledocholithiasis was confirmed in 45 patients: Thirteen patients had nondilated common bile ducts and 20 patients had stones with diamerer < 1 cm. (2) Endoscopic ultrasonography was more sensitive(95.5%) than abdominal ultrasonography (44.4%: P<0.0001) and similar to endoscopic retrograde cholangiography (97.8%). Specificity was same as 100% in 3 diagnostic tools. (3) Endoscopic ultrasonography was superior to abdommal ultrasonography for the diagnosis of choledocholithiasis with nondilated common bile duct(100% vs 15.3%, P<0.0001) and with less than 1cm sized small stone(100% vs 10.0%, P<0.0001). Endoscopic ultrasonography results did not depend on stone diameter or common bile duct dilatation. CONCLUSIONS: Endoscopic ultrasonography could be an accurate and safe diagnostic tool for the diagnosis of choledocholithiasis and could be promising especially in the cases with difficult cannulation of bile duct and gal1 stone pancreatitis.

To evaluate the potential contribution of high resolution ultrasonography(US) and 99mTc scintigraphy in the routine diagnosis of thyroid nodules, we performed thyroid function tests, US, thyroid scintigraphy, and fine-needle aspiration cytology (FNAC) in all 54 patients who initially visit our surgical department for thyroid masses from March 1995 to February 1996. The final diagnoses were made by either repeated FNAC (n=39) or thyroid operations (n=15). Final diagnoses were adenomatous goiters (n=41), simple cysts (n=3), follicular adenoma (n=1), papillary carcinomas (n=8), follicular carcinoma(n=1). The diagnostic impacts of US and 99mTc scintigraphy in all 54 patients were assessed and scored according to the following criteria: when the information provided by either test supported or confirmed (and/or gave some other information for management of thyroid nodules) the final diagnosis, it received a scores of 2 or 3 respectively, while a score 1 was given when the test itself was useless for the differential diagnosis. The scores of US were higher than those of scintigraphy in the diagnoses of adenomatous goiters, cysts, adenomas and carcinomas. However, after statistical analysis with Wilcoxon's signed rank test, US was statistically superior to scintigraphy only in diagnosing adenomatous goiters. These results indicate that current findings in US for differential diagnosis of thyroid nodules are not absolutely superior to those in scintigraphy, but have some benefits in detection of occult nodules in malignancy and differential diagnosis of adenomatous goiters.

10.The clinical observation on diagnosis and treatment of renal injury.
Korean Journal of Urology 1991;32(5):754-761
The clinical observation on diagnosis and treatment was made in 84 patients of renal injury during the period from 1983 to 1989. The results were as follows. 1. The sex ratio of male to female was 3.4:1 and the most favorable age was from 20 to 39 years for 46.4%. 2. The main cause of injury was nonpenetrating injury of which traffic accidents was the most common cause. 3. The associated injuries were seen in 100% of penetrating injury and 55.1% of nonpenetrating injury. The most common associated injury was diaphragmatic injury in penetrating injury and head injury in nonpenetrating injury. 4. Flank pain and hematuria were found in 91.7% and 84.5% in the patients with renal injury, respectively.5. IVP. CT scan, ultrasonography and retrograde pyelography were taken in 63. 50.5 and 2 patients. respectively for the diagnosis of renal injury. The frequency of minor. major and pedicle renal injury were 63.1%. 33.3% and 3.6%, respectively. 6. In minor injury. conservative treatment and renorrhaphy were performed in 98.1% and 1.9% and complication occurred in 3.8%. In major injury. conservative treatment. nephrectomy. partial nephrectomy and renorrhaphy were performed in 46.4%, 32.1%. .14.2% and 7.1%. respectively and complication occurred in 21.4%. In pedicle injury. nephrectomy was performed in 100% and complication was happened in 33.3%. From the viewpoint of the cause of injury, conservative treatment was performed in 16.7% in penetrating injury and 82.1% in nonpenetrating injury. In conclusion. the accurate diagnosis and treatment plan of renal injury with computed tomography are important. When the selection between conservative treatment and operative treatment is difficult, aggressive operative treatment is effective for the preservation of the injured kidney and the prevention of complications.
