Ergovaline and peramine production in endophyte-infected tall fescue: Independent regulation and effects of plant and endophyte genotype.

Peramine and ergovaline have ecological and economical significance because they possess insect and/or mammalian toxicity properties. The relationship between these endophytically derived alkaloids in tall fescue (Festuca arundinacea Schreb.) is unknown.

Compliance with the Royal College of Radiologists' guidelines on the use of pre-operative chest radiographs.

Clinical compliance with the Royal College of Radiologists' guidelines on the use of pre-operative chest radiology was examined in a random sample of patients in four hospitals in England and Wales. Pre-operative clinical data were abstracted from medical reports and, in one hospital, from special chest radiograph request forms completed by clinicians. Seventy-five per cent of patients had clinical indications warranting a pre-operative chest radiograph.
