Limbal and bulbar hyperaemia in normal eyes.
PURPOSE To investigate the appearance of limbal and bulbar hyperaemia in normal eyes, their relationship and the inter-observer agreement of clinical grading. METHODS The right eyes of 120 healthy, non-contact lens-wearing subjects (m = 57, f = 63, median age = 45 years, range 18-77 years) were examined by two trained observers. Limbal and bulbar hyperaemia were scored using the Cornea and Co...
متن کاملPerineural capsaicin treatment attenuates reactive hyperaemia in the rat skin.
The neural mechanisms of reactive cutaneous hyperaemia were studied by using a novel experimental approach: the simultaneous measurement of cutaneous blood flow by laser-Doppler flowmetry in adjacent innervated and chemodenervated skin regions of the rat hindpaw served by the same artery. Transient occlusion of the femoral artery (0.5-6 min) resulted in reactive hyperaemia that was greatly redu...
متن کاملHeel skin hyperaemia: direct compression versus vascular occlusion.
Vulnerability of the heel to ulceration in bed-bound persons is related to direct pressure-induced blood flow decreases. Periodic pressure reduction is a clinical strategy to help prevent ulcers by allowing flow-repayment hyperaemia that has a magnitude and duration thought to be related to the duration of the prior interval of ischaemia. However, there are reasons to question whether effects o...
متن کاملTachykinin inhibition of acid-induced gastric hyperaemia in the rat.
1. Primary afferent neurones releasing the vasodilator, calcitonin gene-related peptide, mediate the gastric hyperaemic response to acid back-diffusion. The tachykinins neurokinin A (NKA) and substance P (SP) are located in the same neurones and are co-released with calcitonin gene-related peptide. In this study we investigated the effect and possible role of tachykinins in the acid-evoked gast...
متن کاملEffect of aminophylline on coronary reactive hyperaemia following brief and long occlusion periods.
The effects of an intracoronary aminophylline infusion, adjusted to give a constant concentration of 25 microgram.cm-3 coronary blood, on the reactive hyperaemic responses following coronary occlusion for 4, 10, and 25 heart beats were investigated in anaesthetised, open-chest dogs. The vasodilator effect of intracoronarily-administered adenosine and the hyperaemic response after coronary occlu...
