With a rapid development of neuroscience, the theories related to the pathophysiology of schizophrenia have been changed a lot from a simple hyperdopaminergic one to the various complicated ones. Among these, the theories regarding prefrontal cortex(PFC) pathology as a cause of schizophrenia are gaining more recognition as the results of neuroimaging and neuropsychological tests in schizophrenia consistently report abnormalities in PFC. Therefore, we first reviewed the unique characteristics of PFC in anatomy, neurochemistry and neurophysiology to enhance an understanding of those ones. Secondly, various neurotransmitter, neurodevelopmental and neural network theories of schizophrenia introduced recently were reviewed in terms of PFC pathology.

OBJECTIVE: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-alpha in the peritoneal fluid(PF) of women with and without endometriosis and infertile women. Design: Prospective and case-control study. Setting: University hospital. Patients: Twenty-nine women with laparotomy or laparoscopic findings of minimal to severe endometriosis, and twenty-eight women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. Main Outcome Measures: PF IL-6 and tumor necrosis factor-alpha levels were determined using commercial ELISA. IL-6 and tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. RESULTS: IL-6 and tumor necrosis factor-alpha concentrations were higher than in the PF of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in PF from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. IL-6 concentrations were higher than in the PF among of infertile women than in fertile women. A significant correlation between PF IL-6 and tumor necrosis factor-alpha concentrations and endometriosis stage III and IV was noted. CONCLUSIONS: Increased PF levels of IL-6 and tumor necrosis factor-alpha in patients with endometriosis may be relate to endometriosis-associated infertility and to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

OBJECTIVE: Endometriosis is a disease affecting a large population of women all over the world. A local sterile inflammation occurs in the peritonel cavity of patients with endometriosis. It suggests that immunological events play a major role in the pathogenesis of endometriosis. We have studied the levels of serveral T cell and monocyte derived cytokines, especially IL-6 (promoter of immune response) and IL-10 (inhibitor of immune response), in the peritoneal fluid of patients with endometriosis to characterize the change of immune response that occurs at the site of endometriosis. Method: This study was performed in Hallym university hospital from October, 1997 to October 1998 and enrolled 29 women with gross or microscopic findings of minimal to severe endometriosis in case group, and 28 women without visual evidence of pelvic endometriosis and with benign gynecologic disease in control group. IL-6 and IL-10 levels in the peritoneal fluid were determined using commercial ELISA and compared between endometriosis and controls and between fertile and infertile women with endometriosis and according to the revised American Fertility Society classification. RESULT: IL-6 was higher and IL-10 was lower in the peritoneal fluid of endometriosis group than of control group. Cyclic variations in the IL-6 concentrations were seen in endometriosis group : the concentrations in the secretory phase were significantly higher than those in the proliferative phase. In endometriosis group, IL-6 concentrations of infertile women were higher than fertile women. Both IL-6 and IL-10 in the peritoneal fluid of endomtriosis group did not show significant correlation according to r-AFS stages. CONCLUSION: Increased IL-6 and decreased IL-10 levels in the peritoneal fluid may be related to infertility and pathogenesis in the endometriosis, suggesting that partially contribute to the disturbed immune regulation observed in endometriosis.

The morphologic abnormalities of the endocrine pancreas that underlie persistent neonatal hyperinsulinemic hypoglycemia and are included under the heading "nesidioblastosis" appears to be heterogeneous. This characteristic morphologic finding is ductuloinsular complexes showing endocrine cells budding off the ductoepithelium and merging with adjacent endocrine cell clusters. A case of nesidioblastosis associated with hyperinsulinemic hypoglycemia occurred in a 6/365 year-old male neonate. Microscopic finding of near totally resected pancreas revealed irregular sized islets and ductuloinsular complexes, both of which contained hypertrophied B cells with a few mitosis. Because of persistent hypoglycemia after first operation, he received second operation 8 days after. This histologic finding was more severe comparative to that of first operation. According to these findings, the pathogenesis of nesidioblastosis may be congenital or developmental defect of a kind of compensatory mechanism by unknown stimuli to acquire persistent hypoglycemia.

Sleep disturbance is a one of common complaints among patients with panic disorder. However, clinicians and researchers did not give much attention to the sleep symptoms of panic disorder yet. Several previous studies suggested that the sleep disturbance in panic disorder is mediated by nocturnal panic attack. In terms of the pathophysiology of panic disorder, nocturnal panic attack seems to be closely associated with the sleep problems in panic disorder. In this article, the authors reviewed various previous studies about sleep of panic disorder and intended to give importance of evaluating sleep disturbances and nocturnal panic attack in panic disorder for both clinical and research purpose.
