[Role of nucleus parabrachialis medialis in the "renzhong" induced pressor response in rabbits]. 1991

Experiments were performed on 18 rabbits, bivagotomized, gallamine triethiodide immobilized and artificially ventilated. The effects of electrical stimulation of "renzhong" (Du 26) area and NPBM, separately and simultaneously, on arterial blood pressure and heart rate were observed before and after electrolytic or chemical lesion of NPBM. Electrical stimulation of "renzhong" area or NPBM, separately could elicit an increase in arterial blood pressure; when both "renzhong" and NPBM were stimulated, the pressor response to NPBM stimulation could affect that of "renzhong" area's. But after electrolytic or chemical lesion of NPBM, stimulation of NPBM could no longer elicit pressor response. On the other hand, the pressor response induced by electrical stimulation of "renzhong" area decreased obviously, after lesion of NPBM or transection of brain stem between NPBM and Nucleus trigemini principalis. These results suggest that NPBM might take part in the pressor response of "renzhong" area stimulation.

D008526	Medulla Oblongata	The lower portion of the BRAIN STEM. It is inferior to the PONS and anterior to the CEREBELLUM. Medulla oblongata serves as a relay station between the brain and the spinal cord, and contains centers for regulating respiratory, vasomotor, cardiac, and reflex activities.

D011149	Pons	The front part of the hindbrain (RHOMBENCEPHALON) that lies between the MEDULLA and the midbrain (MESENCEPHALON) ventral to the cerebellum. It is composed of two parts, the dorsal and the ventral. The pons serves as a relay station for neural pathways between the CEREBELLUM to the CEREBRUM.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
