Isolated fetal ascites may be different from general category of nonimmune hydrops in both prenatal course and prognosis. We experienced one case of isolated fetal ascites of unknown origin treated by in utero ultrasound-directed paracentesis and so present it with brief review of literature.

Diabetes is the most common cause of erectile dysfunction (ED). Oxidative stress has been suggested to be a contributory factor in vascular complications of diabetes in various organs. In the present study, we investigated whether oxidative stress is associated with erectile function in non- insulin dependant diabetes mellitus (NIDDM) rats. Fifty-four Sprague-Dawley rats were the subjects of this study. In each rat, NIDDM was induced by an intraperitoneal injection of 90mg/Kg of streptozotocin on the second day after birth. Based on the diabetic period, they were classified into either short-term or long-term diabetics (avg. 22 weeks, n=18 and avg. 38 weeks, n=20), respectively, and their age-matched controls (n=16). To evaluate the erectile function in each rat, the intracavernous pressure, and latency to maximal pressure, following cavernous nerve stimulation (frequency: 1 Hz, intensity: 3 - 6 V, pulse width: 1 msec, pulse duration: 1 min.) was analyzed. To evaluate both oxidative stress from reactive oxygen species, and antioxidant function as a defense against them, total malondialdehyde and glutathione levels were measured in the corpus cavernosum of the penis, using a spectrophotometric assay. The intracavernous pressure following cavernous nerve stimulation was significantly lower in the long-term (49.8 +/- 9.4 cmH2O) than the short-term diabetics (75.9 +/- 14.8 cm H2O), and markedly decreased in the diabetic rats, compared with their age-matched controls (long-term controls; 60.7 +/- 17.2 cmH2O, short-term controls; 95.2 +/- 20.4 cmH2O). The malondialdehyde content in the corpus cavernosum was markedly increased in the diabetics (2.13 +/- 0.27 nM/mg protein) compared to the controls (1.48 +/- 0.22 nM/mg protein). Furthermore, the glutathione level was significantly decreased in the diabetics, compared to age-matched controls (short-term control; 218.3 +/- 25.6 microM/mg protein, long-term control; 150.2 +/- 9.8 microM/mg protein). In the diabetic groups, it was more significantly decreased in the long-term diabetics (134.8 +/- 11.3 microM/mg protein) than in short-term diabetics (182.1 +/- 18.8 microM/mg protein). NIDDM causes erectile dysfunction, which slowly progresses. Oxidative stress to cavernous tissue may be a contributory factor in erectile dysfunction in diabetics.

Uterine tumors resembling ovarian sex-cord tumors (UTROSCT) are very rare tumors that occur mainly in the uterine fundus of women in reproductive age. These tumors can be classified into group 1 and group 2 by histological results. In group 1, epithelial-like differentiation is partially observed in the tumors. In group 2, sex-cord elements are predominant in uterine mural mass. We experienced UTROSCT group 1 in a 29-year-old woman who complained of severe abdominal pain that started one week after delivery and UTROSCT group 2 case in a 49-year-old woman who complained of dysfunctional uterine bleeding. We report two different types of UTROSCT cases that we experienced.

An ultrasonographic examination revealed increased fetal bladder size and decreased AFI as well as fetal bilateral hydronephrosis at 173weeks' gestation. Diagnosis of the fetal posterior urethral valve syndrome was made. Percutaneous fetal bladder puncture with aspiration and amniocentesis was performed. The fetus was normal male karyotype and with a predicted good renal function(sodium concentration, chloride concentration, and osmolarity at 74 mEq/L, 60 mEq/L, and 148 mOsm, respectively). So, the fetus underwent amnioinfusion and vesico-amniotic shunting procedure (VASP) using a double-basket catheter at 194weeks' gestation in order to prevent development of dysplastic kidneys and hypoplastic lungs. The healthy male baby was delivered at 384weeks' gestation and had normally functioning kidney. Cutaneous vesicostomy was performed for the newborn since the urethral orifice was small. The one year old infant is now well and waiting for urethroscopic valve ablation procedure.

BACKGROUND: Eosinophilic leukocytes are prominent cellular participants in the pathogenesis of allergic disease and asthma. Chemotaxis is still a very useful method in evaluating the response of human eosinophil to novel modulators. Degranulated mast cells and activated T lymphocytes are responsible for the pathophysiology of asthma and tryptase is one of most important proteases released after activation of mast cells. The purpose of this study was to investigate the actions of trypsin and chymotrypsin on eosinophils in terms of chemotaxis and activation. METHOD: Eosinophils were isolated by negative immunoselection from the peripheral blood of atopic donors. Chemotaxis was studied by using micro-Boyden chambers and ECP release was assayed by fluoroimmunoassay. RESULTS: Eosinophil showed a chemotactic response to trypsin. Maximal chemotactic response was with 1000microg/ml trypsin (56.52 +/- 14.50/HPF) which was comparable to PAF. But chymotrypsin showed no significant chemotactic response to eosinophils. Trypsin at the concentration of 10, 100,1000microg/ml induced secretion of ECP, which at the concentration of 10microg/ml represented about 2.7 times of the spontaneous rate of release. Soybean protease inhibitor reduced trypsin induced ECP release. CONCLUSION: Trypsin can induce chemotactic response to eosinophils and activation of eosinophils that can induce secretion of ECP. On the contrary, chymotrypsin showed no direct effect on eosinophils. We propose a role of trypsin on the chemotaxis and activation of eosinophils.

PURPOSE: Acute appendicitis is the most common disease requiring abdominal surgery, but for atypical clinical findings, a preoperative diagnosis is difficult and the frequency of a false positive and false negative diagnosis is high. The authors compared the diagnostic accuracy of a Technetium-99m-ciprofloxacin scan with that of the other diagnostic tools and evaluated its potential for clinical applications. METHODS: Seventeen patients were among those patients who visited the emergency room due to right lower quadrant (RLQ) pain were selected for this study. The decision for primary treatment was based on the clinical findings (RLQ pain, nausea, tenderness, rebound tenderness, leukocytosis, etc) and the radiological findings (abdominal ultrasonogram, abdominal computed tomography, etc). The 99mTc-ciprofloxacin scan was conducted regardless of the decision above. For the patients who underwent surgery, the final diagnosis of acute appendicitis was based on the pathologic result and for patients who did not undergo surgery, the final diagnosis was determined by the clinical course. RESULTS: Seventeen patients were enrolled in this study (7 males, 10 females). The patient's age ranged from 8 to 71 years and the average age was 29.2 years. The diagnostic accuracy of acute appendicitis is presented in order of the clinical findings, the radiological findings and the 99mTc- ciprofloxacin scan as follows: The sensitivity was 100%, 90.9% and 100%; the specificity rates was 33.3%, 50% and 67%; the positive predictive value was 87.5%, 90.9% and 93%; the negative predictive values was 100%, 50% and 100%; the false positive rate was 66.7%, 50% and 33.3%; the false negative rate was 0%, 9% and 0%. The respective p-values for the correlation between these results and the final diagnosis were 0.021, 0.049 and 0.002. CONCLUSION: A 99mTc-ciprofloxacin scan can decrease the false positive and the false negative rate and increase the diagnostic accuracy of acute appendicitis patients.

Heat shock protein 70 (Hsp70) release and its effects on pro-inflammatory cytokine production have been controversial. In this study, we investigated whether Hsp70 could be released from monocytes and activates matrix metalloproteinase-9 (MMP-9) gene expression. Hsp70 overexpression in human monocytic cell line U937 was found to increase PMA- induced MMP-9 expression and enhance cell motility. Hsp70 cDNA transfectants released Hsp70 protein into culture supernatants, and a part of released Hsp70 subsequently was bound to the surface of U937 cells. Addition of culture medium containing the extracelluar Hsp70 led to an increase not only in proMMP-9 secretion, but also the invasiveness of U937 cells through Matrigel or human umbilical vascular endothelial cells (HUVEC) in vitro. Immunodepletion of Hsp70 abolished its effect on MMP-9 expression. The released Hsp70 activated nuclear factor kappa B (NF-kappa B) and activating protein-1 (AP-1), which led to the activation of MMP-9 transcription. Taken together, these results suggest that extracellular Hsp70 induces the expression of MMP-9 gene through activation of NF-kappa B and AP-1.
