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.

Sparganosis is a tissue-invading disease caused hy plerocercoid of Spirometra mansoni91. Usually, uncooked snakes or flogs and infected water are primary sources of sparganosis. Sparganosis found in the lower extremities, abdominal wall, breast, inguinal region and scrotum. Simple radiographs show linear or elongated calcification. Serodiagnostic tests have also heen used widely. Confirmative diagnosis of sparganosis is made by surgical removal of the worm. We experienced a case of sparganosis in a 48-year old male in the calf. We report a case and review related articles hriefly.

Hypertension is a risk factor for developing fatal aortic dissection. Aortic dissection occurs 2~3 times as often in men than in women between ages of 50~70 years old. Among other risk factors, aortic dissection occurs especially in women below the age of 40 years old in pregnancy-related cases. In pregnancy-related cases, aortic dissection occurs in the third trimester and in puerperium, as well as in multiparous women. The writers experienced an aortic dissection related pregnancy. The patient was 32 years old, diagnosis of dissection occurred in the postpartum period. Although, aortic dissection is a rare complication of pregnancy, the knowledge of this may assist the emergency physician save the lives of patients.

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.

Although the introduction of oral phosphodiesterase-5 inhibitors has revolutionized the treatment of erectile dysfunction, there is still a need for new effective therapies for patients who fail to respond or who have severe cardiovascular disease. Stem cell therapy may restore physiological erections following normal endogenous signals. Treatments based on stem cells have the advantages of no inflammation and less immune rejection. Immunohistochemical evidence for nerve preservation and improved erectile function in rats after administration of neural embryonic stem cells intracavernosally has been reported. Potential differentiation of mesenchymal stem cells to endothelial cells and smooth muscle cells after injection into the corpus cavernosum in rats was confirmed. Mesenchymal stem cells alone or mesenchymal stem cells altered by gene therapy with endothelial nitric oxide synthase or calcitonin-related peptide restored damaged erectile physiology and improved erectile capacity in rats. Injection of skeletal muscle-derived cells into the corpus cavernosum improved erectile function. Fetal and cord blood stem cells also can be used as the source of stem cells. Recently, multipotent amniotic fluid-derived stem cells have been isolated. Advances in the research of amniotic fluid-derived stem cells are expected to further raise the hope for stem cell therapy. Stem cell therapy to restore erectile function may represent a fascinating new therapeutic strategy for future treatment.

Lipoblastoma is a benign tumor which frequently arises in the limbs but rarely in the mediastinum, and is common in children under the age of three years. We report a case of mediastinal lipoblastoma in a 27-month-old female child complaining of dyspnea. Plain radiography demonstrated a huge well-defined mass in the me-diastinum, while CT scanning revealed a soft tissue mass with an internal hypodense portion. When radi-ographic images in children under the age of three reveal a soft tissue mass with a fat component in the mediastinum, especially where there is no calcification or a cystic component, lipoblastoma should be included in the differential diagnosis.

Seminal biochemical compositions are to be affected during inflammatory conditions of seminal tract such as chronic prostatitis. Especially chronic prostatitis induces changes in composition of prostatic fluid, and the chronic nature of disease also induces atrophy of prostatic secretory acini and the inflammation of seminal vesicle. We investigated the change of the seminal composition and the possible effect in sperm motility of chronic prostatitis patients. Sperm motility and seminal levels of zinc, citric acid, prostatic acid phosphatase(PAP) and fructose were measured on 12 healthy males and 21 chronic prostatitis patients. Sperm motility in chronic prostatitis patients was decreased and seminal levels of zinc, citric acid, PAP and fructose in control and chronic prostatitis patients were 143+/-10/102+/-7(ug/L), 389+/-17/293+/-25(mg/dl), 446+/-61/ 382+/-28(U/ml), 306+/-7/297+/-6(mg/dl), respectively. The change of zinc was statistically significant. In conclusion, although decrease of seminal zinc in patients with chronic prostatitis was found, there was no convincing evidence to suggest that alterations in seminal composition due to chronic prostatitis lead to decrease of sperm motility.

Inflammatory white blood cells in semen is related to semen quality affecting fertility. The role of inflammatory cells on the seminal levels of various cytokines associated with inflammation and sperm motility is evaluated. Semens from 10 healthy males and 20 chronic prostatitis patients were evaluated for the levels of interleukin(IL)-1a, IL-6, IL-8 and tumor necrosis factor(TNF)-a. Motility parameters were recorded using Hamilton-Thorne computer semen analysis system. Sperm motility parameters such as including average path velocity(VAP), straight line velocity(VSL), curvilinear velocity(VCL), lateral head displacement(ALH), beat frequency(BCF), straightness(STR), linearity(LIN), elongation and area in control and chronic prostatitis patients were 44.9+/-2.5/38.8+/-1.3(um/sec), 36.4+/-2.4/30.5+/-1.1(um/sec), 64.2+/-3.9/ 58.0+/-2.4(Fm/sec), 3.3+/-0.2/4.8+/-0.3tm), 19.8+/-3.7/13.9+/-0.3(Hz), 77.7+/-5.1/78.8+/-1.2(%), 50.6+/-17.5/53.5+/-1.9(%), 66.8+/-5.4/57.8+/-1.1(9%), 2.9+/-0.3/3.8+/-0.1(um/sec), respectively. Statistical significance was noted in VAP, VSL, ALH, BCF, elongation and area. Semen levels of IL-1a, IL-6, IL-8 and TNF-a in control and chronic prostatitis patients are 15.1+/-1.5/52.9+/-14.2 (pg/ml), 10.5+/-2.2/38.3+/-12.2 (pg/ml), 1.60+/-0.38/ 6.02+/-0.26 (ug/L), 11.8+/-2.5 / 21.7+/-4.0(pg/ml) statistically significant in all. For combined parameters, the correlation coefficient of IL-1a and VSL, ALH, Area were 0.40, 0.41, 0.37 respectively which were significant. The correlation coefficient of IL-8 and VAP, VSL, VCL, ALH, BCF, Elongation, Area were 0.48, 0.49, 0.39, 0.41, 0.55, 0.59, 0.66 respectively which were also significant. Seminal inflammatory cytokines are present in increased quantities if inflammatory white blood cells are present in semen and this increase might be related to sperm motility.

Evidence-based medicine is a medical movement combining professional experience with the best scientific research results. Treatment of Kawasaki disease in the acute phase is directed at reducing inflammation in the coronary artery wall and preventing coronary thrombosis, whereas long-term therapy in individuals who develop coronary aneurysms is aimed at preventing myocardial ischemia or infarction. I attempt to summarize the current state of knowledge of the medical management of patients with Kawasaki disease. The recommendations are evidence-based and derived from published data wherever possible.
