[Microbiologic findings in protracted and chronic enterocolitis].

Novel diagnostic methods (immunoblotting, immunofluorescence test) have been proved to be very sensitive and specific for detecting enteropathogenic bacilli. 28 patients with chronic enterocolitis were investigated. In 50% (14/28) of these patients Yersinia enterocolitica could be visualized in biopsies by immunofluorescence. The serum of 8 patients also contained IgA-antibodies against plasmid encoded released proteins of Y. enterocolitica. This paper reports evidence for persistence of Yersinia bacilli in a group of patients with chronic enterocolitis. Further studies must show, if these results may have therapeutic implications.

[Malignant somatostatinoma of the papilla major and minor].

In a 50-year-old man with extrahepatic cholestasis and iron-deficiency anaemia, local operative excision of a 4 cm submucous tumour of the papilla of Vater revealed on histological and immunochemical examination a somatostatinoma. Subsequent duodenopancreatectomy further demonstrated in the surgical specimen a lymph node metastasis and a 5 mm somatostatinoma in the papilla minor. The patient has now been free of symptoms for 12 months on substitution treatment with pancreatic enzymes.

Sleep patterns in cat induced by gammahydroxybutyric acid.

Intravenous injections of gammahydroxybutyric acid (GHBA) (150-200 mg/kg) induce desynchronized sleep (DS) in the cat. This was shown by recording the EEG, eye-movements, the neck EMG, heart-rate and arterial pressure. The decreases in arterial pressure were not different from those recorded during naturally occurring DS. GHBA, given at doses above 200 mg/kg induced anaesthesia, during which arterial pressure was elevated. At the end of GHBA-induced sleep or anaesthesia there was a stage during which the animals were ataxic. The EEG showed a hypersynchronous spike pattern and arterial pressure was markedly elevated.
