“…Edis, Donald & Shepherd (1970) reported a reduction in heart rate following inflation of balloons in the pulmonary vein-atrial junction, particularly when the initial heart rate was high. In the present experiments we observed that an increase in impulse activity occurred in cardiac sympathetic fibres even when the Cloninger & Green (1955), Browse, Lorenz & Shepherd (1966) and Donald & Ferguson (1970). On the other hand, the results of Edis et al (1970), who observed a decrease in systemic vascular resistance following distension of the pulmonary veinatrial junctions with large balloons, are clearly different from the present results.…”

SUMMARY1. Activation of left atrial receptors by distension of balloons at the pulmonary vein-atrial junctions caused an increase in the cardiac sympathetic nerve activity, a decrease in the renal sympathetic nerve activity, and no change in the lumbar and splenic sympathetic nerve activity.2. The cardiac and renal nerve responses to balloon distension were abolished by vagal blockade in the neck.3. The results provide additional evidence that the reflex increase in the heart rate following stimulation of the left atrial receptors is mediated by selective activation of cardiac sympathetic nerve fibres.4. The inhibitory effect of atrial receptor activation on the renal sympathetic nerve activity suggests that a neural factor, possibly involving renal haemodynamics, may be a component of the diuretic response to the activation of the left atrial receptors.5. The results provide further evidence for the selective nature of the pattern of reflex responses to left atrial receptor activation and show for the first time a directionally fractionated response from sympathetic efferent neurones.

When a delay loop was interposed in the extracorporeal circuit between the carotid and femoral artery (Fig.…”

SUMMARY1. Hind limb blood flow was measured in lambs of from 91 days gestation (delivered by Caesarean section) to 1 month after birth (term is about 147 days), under chloralose anaesthesia. Vascular resistance/100 g wet wt. increased progressively with age. There was reflex femoral vascular tone from the earliest age studied, as shown by vasodilatation on cutting the sciatic nerve.2. On asphyxia by cord occlusion reflex femoral vasoconstriction began earlier and was somewhat greater in older foetal lambs. At all ages, and after denervation of the hind limb, there was vasodilatation after local ischaemia, and a vasoconstriction of delayed onset during asphyxia attributed to release of noradrenaline into the circulation. The vasoconstrictor effect of noradrenaline in immature lambs was at least as great as at term or in the new-born.3. Injections of minimal effective doses of cyanide were used to localize possible chemoreceptor sites in foetal lambs. Injection into the left atrium caused a rise of arterial pressure, femoral vasoconstriction and a complex change in heart rate (usually bradycardia) but rarely any respiratory movement. After atropine, cyanide caused a large tachycardia. All responses were much reduced or abolished by cervical vagotomy.4. Injection of the same doses of cyanide into a jugular vein, the right ventricle, pulmonary or common carotid arteries of foetal lambs caused

“…Trauma of the femoral nerve caused less spasm than direct arterial trauma and can be explained by the observation by CLONNINGER & GREEN (1955) that most of the innervation of the vessels of the hind limb is transmitted by the sciatic nerve. The sensory innervation of the arteries has been investigated by e.g.…”

“…The axillary and brachial arteries are supplied and surrounded by sympathetic fibres from the brachial plexus (DE ] ONG 1961). The innervation of the hind limb vessels of the cat has been investigated by MOORE & MOORE (1933), and of the dog by CLONNINGER &GREEN (1955) andZIMMERMAN (1966). CLONNINGER & GREEN found by electrical stimulation of nerves that 89.1 % of the vasculature of the hind limb vessels was innervated by the sciatic nerve, 2.9 % by the femoral nerve and 2.1 % by fibres around the femoral artery.…”
