BACKGROUND AND PURPOSE It has been proposed that stress may contribute to chronic tension-type headache (CTH) through hyperalgesic effects on already sensitized pain pathways in CTH sufferers.

Rats treated with temelastine (SK&F 93,944), a novel histamine H1-receptor antagonist, develop thyroid lesions characterized by hypertrophy and colloid depletion. To investigate the mechanism underlying the lesion the biliary clearance and hepatocellular accumulation of radio-labelled iodothyronines was measured in rats or cultured rat hepatocytes.(More)
The administration of SK&F 93479, a novel histamine H2 antagonist, to Wistar rats has been shown to produce thyroid lesions associated with an increased clearance of plasma thyroxine (T4) and elevated plasma TSH concentrations. To determine if these changes were mediated via an increase in the hepatic clearance of thyroid hormones, the biliary clearance and(More)
A relationship between maternal and child use of general practitioners (GPs) has been shown to exist for some time, however, the reasons for this relationship are not clear and the extent to which this relationship extends to tertiary care is unknown.
