Ischemic colitis still remains largely underdiagnosed despite the fact that it is one of the most common disorders of the large bowel. The aims of the present study were to evaluate the variable histologic findings of ischemic colitis and to find out helpful histopathological features in diagnosis. Retrospective review of the clinical symptoms, underlying diseases, endoscopic findings of 23 patients, and the histologic features of 37 biopsies was done. We analyzed the significant pathologic features in the histologically diagnosed ischemic colitis group and compared the biopsy time between the histologically diagnosed ischemic colitis group and the non-diagnosed group. Comparison of the endoscopic biopsy time between the group that showed significant histologic features and the group that showed no significant histologic features was also done. The age of the patients ranged from 27 to 87 years. Most patients had abdominal pain, hematemesis, and melena. Endoscopic differential diagnoses included ischemic colitis, ulcerative colitis, infectious colitis, tuberculous colitis, Crohn's disease, and pseudomembranous colitis. Histologic features and diagnoses were also variable. The coagulative necrosis of mucosa and the epithelial desquamation were frequently detected in the group pathologically diagnosed as ischemic colitis. The most pathognomonic finding was coagulative necrosis of the mucosa that was almost always detected within seven days after the onset of clinical symptoms. Recognition of variable patterns of ischemic colitis in a biopsy specimen will direct the clinician to evaluate the vascular system. Early endoscopic biopsy is essential for the precise diagnosis of ischemic colitis.

BACKGROUND: Epidural morphine is effective in the treatment of postoperative pain, but the incidence of associated side effects is high. To evaluate the reduction of opioid sideeffects by epidural use of droperidol mixture, this study was performed. METHODS: Randomly sampled sixty patients undergoing upper abdominal surgery were divided into two groups. To assess a reduction of opioid side effects by droperidol, group I (n=30) were received 3mg morphine and 0.15% bupivacaine 10ml through the indwelling epidural catheter before the conclusion of operation, followed by an infusion of 6 mg morphine plus 0.15% bupivacaine 100ml with the two day infusor. Group II (n=30) were treated with the same protocol as group I but 1.5 mg of droperidol was added to initial bolus and 5mg of droperidol to the two day infusor. Analgesic effect and side effect were 48 hours after operation. RESULTS: No significant differences in intensity of analgesiaand sedation were seen. The intensity of nausea and vomiting in the group II was significantly less than in the group I at 8, 12 hours after operation (p<0.05). The intensity of pruritus in group II was significantly less than in group I at 4, 8 hours of postoperative period (p<0.05). The frequency of nausea, vomiting, pruritus and urinary retention in group II were less than in group I. respiratory depression. Epidural injection of droperidol did not result in any local or systemic side effects. CONCLUSION: The addition of epidural droperidol significantly reduced the side effects of epidural morphine without altering the effect on analgesia.

OBJECTIVE: Several water channels (aquapoins; AQP) that belong to the MIP (major intrinsic protein) family have identified. In the selected tissues including red blood cells or renal tubules, water movements are abundant and/or physiologically important. Unexpectedly, a high water permeability of human and ram sperm has been reported. Recent studies showed that AQP7 and AQP8 are present in testes so that the high water permeability of human sperm suggested to be mediated by AQPs. METHOD: To identify the identity of aquaporins expressed in testes, RT-PCR was performed using degenerative primers, which were designed to correspond to highly conserved sequences surrounding the Asn-Pro-Ala (NPA) motifs in the aquaporins. New expressed AQP series were reconfirmed by immunohistochemical study using rabbit polyclonal antibodies. RESULTS: DNA sequencing of PCR products revealed that AQP2 and AQP3 mRNA as well as AQP7 and AQP8 are expressed in human and rat testes, AQP2 are expressed in spermatozoa, interstitial cells and myofibroblasts and AQP3 are expressed in myofibroblasts of semineferous tubules on immunocytochemical stain. CONCLUSION: These results indicate that multiple aquaporins are expressed in testes, and that they may have important roles in the spermatogenesis and the germ cell function of testis.

PURPOSE: We compared the clinical manifestations of patients with tsutsugamushi disease between children and adults. METHODS: From January 2003 to December 2012, 768 patients diagnosed with tsutsugamushi disease were retrospectively reviewed, and the clinical characteristics, laboratory findings, and complications were compared between children and adults. RESULTS: No patterns of annual increases in the number of patients were noted in both children and adults. The higher incidences occurred in October and November respectively. By gender, male outnumbered female in children, but the opposite trend was seen in adults. By residential area, the urban distribution of children was higher than that of adults. Rashes (P=0.001) and eschar (P=0.004) were more common in children, while myalgia was more common in adults. Children had a high prevalence of anemia (P=0.041), and low incidence rates of thrombocytopenia, abnormal liver and renal function. Children yielded better results in the duration of their hospital stay and the incidence of complications (P<0.001). A comparison of the therapeutic effects of doxycycline and macrolide antibiotics, which was performed only on the children, did not reveal any significant differences. CONCLUSION: Compared to adults, children had higher incidence rates of male patients and more often suffered from rashes and eschar. Children yielded better results in the laboratory findings and duration of the hospital stay and complications. Therefore, when children are suspected to have tsutsugamushi disease, especially during its peak occurrence period, detailed physical examination and serological test should be performed to ensure a prompt diagnosis, and the use of macrolide antibiotics, which have fewer side effects, is expected to yield the same therapeutic effects.

Even though phototherapy is an effective means of treating hyperbilirubinemia, adequate binocular shields are essential to prevent light hazard of retina during phototherapy. The phototherapy to young albino rabbits was performed under various conditions; exposured for 12, 24, and 48 hours, continuity or intermittence of irradiation, and use of shields. Although there was no definite pathologic change in indirect ophthalmoscopic examination, severe damage was seen at electron microscopic level. In all experimental groups, swelling and edema of photoreceptor were seen. at right after phototherapy. Futhermore, more severe damage was seen in case of intermittent irradiated group and prolong exposed group. In mydriatic eyes, severity of damage was similiar to non mydi iatic eyes, but area of retinal damage was more extensive than non-mydriatic eves.. In control group which was protected by binocular shields during phototherapy, no significant abnormality was found.
