Objective To investigate the mechanism of the clinical effect of electroacupuncture of the pudendal nerve on the lumbar and lower limb symptoms caused by lumbar spinal canal stenosis, we studied changes in sciatic nerve blood flow during electrical stimulation of the pudendal nerve in the rat. Methods Using rats (n=5), efferent electrical stimulation to the pudendal nerve was performed and sciatic nerve blood flow was measured with laser Doppler flowmetry. Simultaneously, changes in the blood pressure and cardiac rate were measured. Furthermore, the effect of atropine on these responses to the stimulation was also studied. Results Electrical stimulation of the pudendal nerve significantly increased blood flow in the sciatic nerve transiently without increasing heart rate and systemic blood pressure. The significant increase in the sciatic nerve blood flow disappeared after administration of atropine. Conclusion Electrical stimulation of the pudendal nerve causes a transient and significant increase in sciatic nerve blood flow. This response is eliminated or attenuated by administration of atropine, indicating that it occurs mainly via cholinergic nerves.

Bilateral destruction of perikarya in the fastigial nucleus (FN) of the rat with the cytotoxic agent kainic acid (0.5 mg) did not alter the blood pressure (BP) increases observed during monopolar electrical stimulation (100 microA, 50 Hz, 0.5-ms pulse width) of this region. BP increases in control animals were 30 +/- 8 mm Hg, whereas BP increased 30 +/- 7 mmHg in kainic acid-lesioned rats. Furthermore, picrotoxin (100 ng) and muscimol (25 ng) microinjected unilaterally into the FN of conscious, unrestrained rats produced postural asymmetry but no change in BP or heart rate. These data suggest that the FN pressor response may be due, at least in part, to stimulation of axons of passage.

Electrical stimulation of the anterior limbic region in Nembutal-anesthetized cats evokes uterine contractions similar to those elicited by the injection of 50–100 mu of synthetic oxytocin. The contractions of the uterus caused by cortical stimulation must be related to release of an oxytocic agent carried through the blood stream, since transection of the spinal cord together with the severance of the vagi did not prevent the contractions. A moderate rise in blood pressure that appeared in the animals with spinal cord transection also suggests release of vasopressin.

SUMMARY Discrete portions of the afferent path of the milk-ejection reflex have been explored in the brain of the lactating guinea-pig. Both intramammary pressure and arterial blood pressure were recorded to detect release of oxytocin and vasopressin. It was found that the milk-ejection responses which occurred after electrical stimulation of the pathway in the midbrain and hypothalamus were caused by the release of oxytocin without detectable release of vasopressin. A mixture of oxytocin and vasopressin, in the ratio of approximately 3:1, was released only after electrical stimulation of the rostral tuberal region of the hypothalamus adjacent to the pituitary stalk. It is concluded that the afferent path in the brain of the guinea-pig studied is concerned with the preferential release of oxytocin from the neurohypophysis and that it is the pathway of the milk-ejection reflex.
