Regional blood flow in normotensive and spontaneously hypertensive rats. 1976

K Nishiyama, and A Nishiyama, and E D Frohlich

Regional distribution of cardiac output in unanesthetized spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) and Wistar NR male rats (10 each group; average age 21 wk) was determined using two 15-mum microspheres (141Ce and 85Sr) injected 10 min apart through a left ventricular (LV) cannula. Fractional flow distribution was expressed as percentage activity of injected dose (average of the two measurements). Despite differences in body and organ weights, organ flow distribution did not vary between SHR and WKY, except for heart and testes (P less than 0.025). However, differences did not exist between SHR and NR with respect to heart, brain, lungs, spleen, and adrenal flows (P less than 0.05).

D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
