Adhesion of Corynebacterium renale, Corynebacterium pilosum, and Corynebacterium cystitidis to bovine urinary bladder epithelial cells of various ages and levels of differentiation.

The adhesion of Corynebacterium renale, Corynebacterium pilosum, and Corynebacterium cystitidis to various epithelial cell layers of bovine urinary bladders was examined. Adhesion was most efficient to the urinary sediment epithelial cells and the superficial cells immediately before shedding, followed by the remaining superficial cells and intermediate cells in this order, and least efficient to the deeper intermediate and basal cells. Incubation of the intermediate cells for 6 h increased the number of bacteria that adhered to these cells.

Paired anterior spinal arteries in a case of locked-in syndrome.

Paired anterior spinal arteries have rarely been demonstrated angiographically, although several anatomical studies have shown that they are not uncommonly observed. This report describes the angiographic and autopsy findings of such a variation, which was observed in a 65-year-old man with a locked-in syndrome. The paired trunks of the anterior spinal artery were visualized in a retrograde fashion through the left inferior thyroid artery and a radical branch at the 5th cervical level by left retrograde brachial angiography. The uppermost segments of either vertebral artery and the lower portion of the basilar artery were opacified through these channels. The autopsy confirmed the paired trunks of the anterior spinal artery, occlusion of the vertebral arteries just caudal to the origin of the main branches of the anterior spinal artery, and an old infarct involving the pontine tegmentum and cerebellum.

Spectroscopic evidence for the generation of singlet oxygen in the reduced nicotinamide adenine dinucleotide phosphate-dependent microsomal lipid peroxidation system.

In the presence of Fe3+-ADP and NADPH, washed rat liver microsomes at 37 degrees and at pH 7.5 emitted ultraweak light with the peroxidative cleavage of endogenous lipid. The main light-emitting species of this system was analyzed spectroscopically in the visible region and estimated to be singlet oxygen. The addition of superoxide dismutase or catalase did not inhibit the light emission significantly. It is unlikely therefore that superoxide anion and OH are involved in the generation of singlet oxygen in the present system.
