Our previous studies have shown that central administration of angiotensin II (ANG II) causes vasopressin release in the near-term fetus in utero as evidence that the hypothalamic-neurohypophysial system has relatively matured before birth. However, it is still unknown whether the vasopressin controlling centers have been functionally developed in younger(More)
The renin-angiotensin system plays an important role in cardiovascular control. Intracerebroventricular (i.c.v.) angiotensin (ANG) II causes a reliable pressor response in the fetus at 90% gestation. To determine the roles of brain AT1 and AT2 receptors in this response, the effects of the central AT1 and AT2 receptor antagonists losartan and PD123319 were(More)

SD rats were used to study the change of Fos-like immunoreactivity (FLI) in the lumbar spinal cord by traumatic pain following hind limb amputation and the effect of electro-acupuncture (EA) at "Huatuo Jiaji point" on it. The results showed (1) FLI cells induced by amputation were found in all of the I-X laminae of the ipsilateral spinal cord, but most of(More)
