Contiguous but dissimilar epithelial neoplasms of the urinary bladder.

An unusual tumour of the urinary bladder is described. It consists of two distinct nodules each with a quite different histological appearance, one being mucus-secreting adenocarcinoma, the other transitional cell carcinoma. Where the nodules are in contact there is little intermingling of the two histological patterns and it is suggested that the findings are probably due to the collision of two separate neoplasms. Metaplastic changes are present in the bladder mucosa adjacent to the tumour. The significance of these changes in the pathogenesis of adanocarcinoma is discussed.

Human cdc2 protein kinase is a major cell-cycle regulated tyrosine kinase substrate.

cdc2 is a catalytic subunit of a protein kinase complex, called the M-phase promoting factor, that induces entry into mitosis and is universal among eukaryotes. In HeLa cells, cdc2 is shown to be the most abundant phosphotyrosine-containing protein and its phosphotyrosine content is subject to cell-cycle regulation. One site of cdc2 tyrosine phosphorylation in vivo is selectively phosphorylated by pp60c-src in vitro.

The effects of sensory integration therapy on nystagmus duration, equilibrium reactions and visual-motor integration in reading retarded children.

Previous research on the effects of sensory integration therapy on vestibular processing dysfunction has not used an appropriate control group design. Using a control group, this research investigated the effects of sensory integration therapy on nystagmus duration, equilibrium reactions and visual-motor integration in 26 children with reading retardation. The sample had average intelligence but showed depressed nystagmus duration, problems in equilibrium reactions and delays in visual-motor coordination. Sixty-six sessions of therapy did not significantly affect duration, equilibrium or visual-motor integration.

A quantitative analysis of the afferent innervation of the organ of corti in guinea pig.

A quantitative analysis of the afferent innervation of the organ of Corti was made on normal and vestibular nerve-sectioned guinea pigs. Section of the vestibular nerve at the internal auditory meatus provided an efficient means of eliminating the efferent innervation to the cochlea without significant loss of afferent fibres. Nerve counts on normal and de-efferented animals revealed that about 10-15 % of the cochlear afferent innervation supplies the outer hair cells. The remaining 85-90% of afferent fibres innervate the inner hair cells. As in cats, all tunnel spiral bundle fibres and upper tunnel crossing fibres were efferent to outer hair cells. Since unmyelinated fibres in the osseous spiral bundle were not counted, quantitative analysis of the efferent innervation to inner hair cells could not be made. However, a significant loss of myelinated fibres in the osseous spiral lamina after vestibular nerve section confirms that many myelinated efferent fibres are present in this region.
