UNLABELLED It was our aim to study the within-day stability and between-day repeatability of ultraviolet B (UVB) light-induced primary and secondary hyperalgesia over 10 h. Twenty hours after UVB irradiation of a skin spot (r = 2.5 cm) on the upper leg of 8 healthy volunteers the areas of secondary hyperalgesia to pinprick and pain tolerance thresholds to(More)
The analysis of drug's influence on peripheral and central sensitisation can give useful information about its mode of action and can lead to more efficacy in the treatment of pain. Peripheral inflammation is associated with peripheral expression and up-regulation of cyclooxygenase 2 (COX-2) in the CNS. The relative contribution of COX-2 mediated central(More)
AIM To determine the effects of various mixtures of O(2) and CO(2) on retinal blood flow in healthy subjects. METHODS A randomised, double masked, four way crossover trial was carried out in 12 healthy male non-smoking subjects. Gas mixtures (100% O(2), 97.5% O(2) + 2.5% CO(2), 95% O(2) + 5% CO(2), and 92% O(2) + 8% CO(2)) were administered for 10 minutes(More)
OBJECTIVE Although rofecoxib has very high selectivity for cyclo-oxygenase 2 (COX-2), supratherapeutic rofecoxib concentrations (> 1000 mg) inhibit purified human COX-1 in vitro and TXB2 formation in vivo. It is therefore possible that higher doses of rofecoxib may affect platelet function. This could be important if rofecoxib is given to thrombocytopenic(More)
