1. In pithed rats, the blood pressure effects of ATP, alpha,beta-methylene ATP (mATP), alpha-adrenoreceptor agonists and of electrical stimulation of the thoracolumbar sympathetic outflow were studied in the absence and presence of mATP, suramin and adrenoreceptor antagonists. 2. ATP elicited an initial rise in mean blood pressure followed by a decrease and(More)
The influence of previous pharmacotherapy or intra-aortic balloon counterpulsation (with thiamine infusion) on the effectiveness of reperfusion of the left anterior descending (LAD) coronary artery after 150 minutes of occlusion has been studied in dogs. The infarct size was determined by morphometric method 20 hours after the onset of ischaemia.(More)
The dose-response curve for the vasopressor effect of alpha, beta-methylene ATP in pithed rats was influenced by four suramin-related drugs (each at 100 mumol/kg). The curve was shifted to the right by a factor of 8 by 'compound 3' and by a factor of 2 by two other derivatives, but was not affected by the fourth analogue. Compound 3 had no effect on the(More)
Soil structure is often severely affected during high intensity burning, while low intensity prescribed burning has often been thought to have a low or neutral effect on soil aggregation. In this issue of Plant and Soil, (Albalasmeh et al. 2012) report a novel mechanism of aggregate disruption during low intensity burning that may explain some contradictory(More)
