Primary adenocarcinoma of the appendix is rare, especially the colonic type. We report a case of appendiceal adenocarcinoma of colonic type associated with perforating peritonitis after aorto-femoral artery bypass surgery. A 79-year-old woman presented with fever and pain in the right lower abdomen. She had undergone aorto-femoral artery bypass surgery due to arteriosclerosis obliterans 6 months earlier. Abdominal ultrasonography and computed tomography showed a suspected pool of fluid surrounding the artificial vessel and a mass lesion in the upper end of the fluid collection. These findings suggested localized peritonitis due to appendiceal perforation. Emergency laparotomy showed a pool of pus around the artificial vessel and inflamed appendix, which adhered to the surrounding tissue. The mass was excised in combination with an i...

Genetic variation of hepatitis C virus was assessed. We prepared RNA fractions from 21 patients' sera which were positive for hepatitis C virus RNA, synthesized their cDNAs, and amplified fragments, 406 base pairs, encoding a putative core protein, by polymerase chain reaction. One of them, N 15, was cloned and sequenced. N 15 showed 92.4% homology at the nucleotide level and 97.0% homology at the amino acid level compared with HC-J 1 which is the first isolated clone in Japan and similar to that isolated in USA. By restriction fragment length polymorphisms analysis, 14 out of 21 patients (66.7%) showed the same pattern as N 15. No patients showed the pattern of HC-J 1. We could not find a correlation between the genetic variation and clinical features of hepatitis C virus infection. These results indicate that the region, which enc...

1. An apparatus for the simultaneous measurements of volume change, fluorescence intensity of pyridine nucleotides and oxygen consumption of mitochondria has been constructed. 2. Oxygen consumption is measured by the rotating platinum electrode with a modification of Hagihara's system, attached in a cuvette of the apparatus. 3. Volume changes of mitochondria (swelling-shrinkage) are measured by the 90° light-scattering at 650 mμ. 4. Relative fluorescence intensity of pyridine nucleotides is measured by the fluorometer: for the excitation, a bright light at 365 mμ. line of mercury lamp is isolated through the filter and exposed to the mitochondria suspended in a cuvette of the apparatus, and fluorescent emission is analyzed by a grating mirror monochromator. 5. The scattered light at 650 mμ. is not affected by the exci...

The aim of this study was to reveal the clinical features of anterior urethral recurrence in patients with superficial bladder cancer, and to determine the appropriate treatment. Three hundred and three patients with superficial bladder cancer, who were newly diagnosed and initially treated conservatively in our hospital between 1965 and 1990, were followed for at least 5 years and their clinical outcomes were analyzed. Clinical factors, including anterior urethral recurrence, were evaluated statistically regarding tumor progression. Eight patients (2.6%) had anterior urethral recurrence following superficial bladder cancer. Twenty-four patients (7.9%) had tumor progression and 149 (49.2%) had tumor recurrence. In a multivariate analysis using a logistic model, anterior urethral recurrence was the most important factor, followed by ...

Aus den bisher aufgefuhrten Ergebnissen konnte rch kurz folgende Schlusse ziehen : 1. Das Warmeisolationsvermogen der aus der Quercus dentata hergestellten Korkplatte ist ungefahr gleich dem der Asphalt-Korsil-platte, und zwar ubertrifft die erstere, genau gesagt, die letztere darin ein wenig. 2. Beim Anheizen des Zimmers ist die Zufuhr einer groβeren Warmemenge vorteilhafter als die einer geringeren. 3. Bei beiden Isolationsplatten ist eine Warmespeicherung kaum nachweisbar. 4. Die Warmeleitzahl betrug bei der Abemaki-Korkplatte 0.056 Cal / m2 st ℃, bei der Asphalt-Korsilplatte 0.064 Cal / m2 st ℃.

Man bestimmte die Gerinnungszeit einer Mischung von 0.1 ml des frischen Zitratplasmas, 0.1 ml einer Epsilon-Aminokapronsäure-Lösung in Konzentrationen von 0, 02, 0.5, 2.5, 10, 20, 50 und 100 gamma, 0.1 ml CaCl² Lösung und 0.1 ml Michaelis' Puffer. Die erwähnten EACA-Konzentrationen hatten keinen charakteristischen Einfluss auf die Rekalzifikationszeit des frischen und des gelösten lyophilisierten Plasmas.

The relationship between segmental mobility and the organisation of thoracic stretch receptors was examined in the deep-sea isopod Bathynomus doederleini, which shows a developed adaptive behaviour during digging. The movements of segments during digging were analysed from video recordings, which showed that a large excursion occurred in the anterior thoracic segments. Dyefills of axons revealed four types of thoracic stretch receptor (TSR): an N-cell type (TSR-1), a differentiated Ncell type (TSR-2), a muscle receptor organ (MRO)-type with a long, single receptor muscle (TSR-3) and an MROtype with a short, single receptor muscle (TSR-4 to TSR-7). Physiologically, TSR-1 and TSR-2 are tonic-type stretch receptors. TSR-3 to TSR-7 show two kinds of stretchactivated responses, a tonic response and a phasico-tonic response in which respo...

It has been indicated that, when fatty acid iron is administered orally, the iron compound is split into iron and fatty acid and absorbed by different mechanisms.
