CEREBRAL BLOOD-FLOW IN POLYCYTHqMIA

The Lancet, 1977
Cerebral blood-flow (C.B.F.) has been measured in 16 patients with polycythaemia of differing severity. The mean C.B.F. was 37-9 ml/100 g/min, which is significantly below the normal level of 69-1 (S.D. 9-3) ml/100 g/min (P less than 0-001). C.B.F. measurement was repeated after venesection in 15 of the patients. Lowering the haematocrit from a mean of

Cerebral Blood Flow in the Rat

American Journal of Physiology-Legacy Content, 1958
The cerebral uptake of iodoantipyrine (I131) was measured in anesthetized rats as a function of time after a single intravenous injection. The cerebral content stabilized in 7–9 seconds and remained constant for 64 seconds indicating that the brain and body had the same extraction ratio for the label.

Cerebral Blood Flow in Schizophrenia

Archives of General Psychiatry, 1983
To the Editor— The article "Regional Cerebral Blood Flow in Schizophrenia" by Mathew et al (Archives1982;39:1121-1124) deals with one of the major interfaces between the study of cerebral circulation and psychiatric conditions, and constitutes an important contribution to the field. Therefore, it is regretable that we must point out major problems and
