A mixed colloid cyst-xanthogranuloma of the third ventricle is described. The xanthogranuloma associated with the cyst completely occupied the third ventricle. On light microscopy, a single epithelial layer with a basal lamina was seen lining the cyst wall. Electron microscopic study revealed three different kinds of cells in the epithelial layer: ciliated,(More)
We investigated the efficacy and the mechanism of action of EM523L, a nonpeptide motilin agonist (motilide), on the stimulation of gastric emptying and on the release of gut peptides after ingestion of a solid meat in normal controls (n = 8) and in diabetic patients (n = 8) with signs of neuropathy. A dose of 2 mg EM523L was administered IV over 15 min just(More)
We describe two cases of early toxic shock syndrome, caused by the superantigen produced from methicillin-resistant Staphylococcus aureus and diagnosed on the basis of an expansion of T-cell-receptor VBeta2-positive T cells. One case-patient showed atypical symptoms. Our results indicate that diagnostic systems incorporating laboratory techniques are(More)
Diurnal variations in concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), corticosterone, estradiol-17 beta and estrone in serum were investigated in 27- to 35-day-old female rats maintained on a 14-hour light and 10-hour dark schedule. Groups of 6-8 rats were decapitated at 3-hour intervals(More)
A case of a suprasellar epithelial cyst in a 48-year-old man is reported. The cyst was lined with two different types of stratified epithelium: one was two to three or more layers of squamous cells with overlying ciliated columnar cells and goblet cells at the surface and the other was tyical stratified squamous epithelial cells. The tumor was neither a(More)
