In eight anesthetized mongrel dogs, the pumpless ECMO applied between the femoral artery and vein was performed under the condition of hypoventilation for 24 hours. The methods were same as the first and second reports, except the pumpless ECMO was used. The abnormal parameters in the cardiovascular and respiratory system (blood gas analysis and end(More)
We developed a 3D display using an LCD display panel and a grating film for stereoscopic viewing. The display screen is divided in half in order that left and right regions provide the stereoscopic images for left and right eyes. Because both stereoscopic images are not in the same position, it is difficult for the observer to view the 3D image by the(More)
In order to determine any possible influence of climatic variables on the incidence of acute aortic dissection (AAD), we reviewed all patients with a diagnosis of AAD treated at Yokohama City University Urafune Hospital between January 1994 and December 1997 retrospectively. One hundred and eight patients with AAD were admitted into the hospital during the(More)
To search for a more suitable qualification indicating watchful waiting, we performed a retrospective study against early-stage prostate cancer patients managed without initial treatment. Thirty-three patients who had not been treated for more than 6 months after diagnosed as T1c or T2 prostate cancer were studied. The median values of total observation(More)
We report two cases of 2.8-dihydroxyadenine stones due to partial deficiency of adenine phosphoribosyltransferase. The first patient is a 41-year-old female. Radiologic examination revealed left radiolucent renal stones and contracted kidney. Left nephrectomy was performed. Infrared spectrometric analysis of the stones revealed 2.8-dihydroxyadenine calculi.(More)
We evaluate the safety and feasibility of laparoscopic radical nephrectomy for renal tumors. Between September 1993 and October 2001, 18 patients with renal tumors underwent laparoscopic radical nephrectomy. The mean patient age was 57.1 years ranging from 36 to 78. Clinical stage was T1N0 in all patients. The mean tumor diameter was 4.0 cm ranging from 1.8(More)
The electrocardiogram (ECG) is used as a standard monitoring method during anesthesia and operation. But during the operation of severely burnt patients, the electrodes for ECG cannot be placed on the ideal points for the standard limb leads. We tried the indirect monitoring of the ECG. We placed the electrodes on the sheet over the operating table, and(More)
