Generally, headed reinforcement offers several advantages over straight bar or hooked bar anchorages to develop reinforcement in concrete members. The purpose of this study is to investigate the shear behaviors of reinforced concrete deep beam with headed reinforcement. Five deep beam specimens are designed to study the anchorage capacity of headed reinforcement as well as the contribution of H-bar and V-bar to the shear. Two anchorage types, standard 90-degree anchorage and headed reinforcement, are considered in design. From the tests, it is shown that In the test results, headed reinforcement is able to replace standard 90-degree anchorage as the anchorage method. The evaluation on the contribution of H-bar and V-bar in current design code for deep beam shows that the former is overestimated 75% and the latter is overestimated 17%.

Heat stroke, a medical emergency, occurs when the body's thermal regulation is upset and unable to dissipate adequate amounts of heat with a rise in body temperature. It is characterized by hyperpyrexia, with a core temperature of 40˚C or more. hot dry skin, and central nervous system disturbance and usually results in rhabdomyolysis and multiorgan failure. Our case, a 43-year-old healthy male, was caused by a marathon, half course, on a sunny day in late summer. He suddenly fell down on the road and was delivered to a nearby hospital, where a seizure developed. He was transfered to our hospital and then displayed Central Nervous System disturbance, hot dry skin, acute liver failure, rhabdomyolysis, anurlc acute renal failure, and disseminated intravasculular coagulopathy. He was treated with general supportive care and hemofiltration. Despite the aggressive management, he died of shock on the fifth day after admission.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

A common form of relapse in adenocarcinoma of the stomach is intraperitioneal dissemination, in fact, among gastric adenocarcinoma patients who have undergone surgery intended to cure, approximately 50% of the patients develope initial recurrence in the peritoneal cavity regardless of the anatomic site of the primary tumor within the stomach. The efficacy of systemic postoperative chemotherapy to prevent peritoneal recurrence of gastrric adenocarcinoma is not satisfactory. There is still a great need for improved therapeutic strategies on the disseminated microscopic disease and small miliary nodules remaining on the peritoneal surface or lymphatics after operation. The authers have made fluorouracil-polyglycolic acid composite disks(Fu-PGA disks) with fluorouracil and biodegradable polymer: polyglycolic acid for more effective intraperitoneal chemotherapy. We inserted the Fu-PGA disk(s) in the peritoneal cavity of rat and pharmacokinetic study was performed to measure fluorouracil concentration in the peritoneal fluid, plasma, liver, kidney and heart tissue at 24 hour, 72 hour and 168 hour after insertion of Fu-PGA disk(s). Myelosuppressive action of this composite also was determined following its administration. The data of this study suggested that Fu-PGA composite will be a new device releasing drugs in a controlled manner and having targetability to peritoneum, and this device will be improving the efficacy of intraperitoneal chemotherapy for gastric adenocarcinoma.

Objectives : This naturalistic retrospective study investigated the effectiveness of ziprasidone measured by mean improve-ments of the Cltnical Global Impression (CGI-I). Secondary objectives included prescribing patterns, tolerability and safety. Methods : From May to July 2006, 98 psychiatric patients who have been taking ziprasidone for at least 2 weeks were selected. Their current clinical statuses were assessed by the interview and laboratory tests including electrocardiogram (ECG). Data on DSM-IV diagnoses, dosing, concomitant psychotropic medications, clinical changes, adverse effects, and laboratory findings were collected retrospectively. Results : Ziprasidone was mostly prescribed for a switch from another antipsychotics for the treatment of schizophrenia. Two main reasons for a switch were unsatisfactory efficacy and poor tolerance, especially weight gain, of the preceding anti-psychotic medication, Participants as a whole showed mean 2.7±1.0 of the CGI-Improvement. Significant weight reduction after switching to ziprasidone occurred, which was related to the clinical improvement. No significant increase of the QTc interval except one case was observed. Conclusion : The present study confirmed previous tolerability and safety data of ziprasidone as well as the results of its effectiveness.
