UNLABELLED The long-term effect of percutaneous electrical nerve stimulation (PENS) on chronic low back pain (LBP) is unclear. We evaluated the number of sessions for which PENS should be performed to alleviate chronic LBP and how long analgesia is sustained. Patients underwent treatment on a twice-weekly schedule for 8 wk. Group A (n = 18) received PENS(More)
Heme oxygenase-1 (HO-1) is induced by oxidative stress and is thought to confer protection against oxidative tissue injuries. HO-1 catalyzes the conversion of the heme moiety of hemeproteins, such as hemoglobin, myoglobin, and cytochrome P450, to biliverdin, liberating carbon monoxide (CO) in the process. CO reacts with hemoglobin to form carboxyhemoglobin.(More)
In order to clarify acute-phase response in brain, we investigated induction of metallothionein (MT) genes by administrating an endotoxin (lipopolysaccharide) in rat intraperitoneum. We performed in situ hybridization on the serial brain sections to identify the cells expressing the MT genes in acute-phase. After endotoxin administration, transcripts of MT(More)
Metallothionein (MT) is induced by various types of oxidative stress. However, whether or not MT is induced in renal ischemia/reperfusion injury, in which oxidative stress is believed to play a major role, remains unknown. The present study investigated MT expression in the kidneys of rats with ischmic acute renal failure (IARF). Rats were subjected to 60(More)
BACKGROUND The GlideScope videolaryngoscope is a new device for endotracheal intubation, which provides a view of the glottis without alignment of the oral pharyngeal and tracheal axes. The purpose of this study was to evaluate the performance of the GlideScope in patients. METHODS We evaluated the performance of the GlideScope" in 200 consecutive(More)
This report describes usefulness of intraoperative transesophageal echocardiograpy (TEE) based on 773 cases we experienced in 7 years. We assessed residual lesions, ventricular function and preload with TEE. We found a case with stenotic lesion in her lateral tunnel which TEE revealed after Fontan procedure. We also ensured that no micro air bubble was in(More)
to drug therapy and failed to respond to catheter ablation. In June 1996, the patient was admitted to the intensive care unit (ICU) of Okayama University Medical School for further management. On admission, frequent VT had caused marked right heart failure, and the central venous pressure (CVP) was approximately 20mmHg. The patient was immediately treated(More)
We report a case of central retinal artery occlusion after anterior-posterior fusion of the lumbar spine. The patient suddenly lost his vision of the right eye in the ICU just after the end of long procedure for anterior-posterior fusion of the lumbar spine. The patient was diagnosed as having central retinal artery occlusion, and treated successfully with(More)
Surgical exposure and accurate closure of a ventricular septal defect with a membranous septal aneurysm beneath the septal tricuspid leaflet carries a risk of tricuspid valve dehiscence and conduction disturbances when the septal leaflet is detached along the tricuspid annulus. To avoid these problems, we use a radial incision to expose and close(More)
BACKGROUND Jichi Medical University Hospital established a new residency program in 2004, which restricted the working time of junior residents to less than 80 hours for one week involving conferences and lectures. METHODS We evaluated the working conditions of non-anesthesia residents in the department of anesthesia from April 2005 to March 2006. (More)
