Neurohumors and Other Pharmacologically Active Substances in Cerebrospinal Fluid: A Review of the Literature **
There has been a considerable resurgence of interest in recent years in analysis of cerebrospinal fluid in neurological and psychiatric disorders. Four monographs and a review article have summarized much of the pertinent literature."' '5'° The purpose of this review is to call attention to an area that has not been adequately described in the publications referred to above. It will comprehensi...
متن کاملNeurohumors in the Brain **
About 25 years ago, after Loewi had produced simple, direct and convincing evidence for chemical transmission at neuro-effector junctions in the heart and Dale had provided similar evidence for the neuromuscular junction, Sir Charles Sherrington made it clear that he had foreseen the possibility of chemical transmission at synapses in the central gray matter. At that time (1935) Sherrington tol...
متن کاملHemoglobin adducts as a marker of exposure to chemical substances, especially PRTR class I designated chemical substances.
Many new biomarkers are being studied, in addition to classical biomarkers, such as chemical substances and their metabolites in blood and urine and modified enzymes. Among these new biomarkers, hemoglobin adducts are thought to be especially useful for the estimation of chemical exposures. We review here the use of biomarkers for monitoring exposures to nine substances, mainly focusing on PRTR...
متن کاملThe Chromatophoral Neurohumors of the Dogfish
1. The common dogfish, Mustelus canis, as is well known, exhibits two temporary extremes of tint, one dark, the other light. The dark phase is induced by a secretion from the pituitary gland which is carried in the blood, hence a substance soluble in water (a hydroneurohumor). The light phase is under the control of nerves and cannot be excited by blood from a light fish. 2. When an olive oil o...
متن کاملSome properties of purified phospholipase D and especially the effect of amphipathic substances.
1. The soluble phospholipase D of cabbage was purified by heat treatment, acetone precipitation and electrophoresis on a density gradient of aqueous glycerol. 2. The purified enzyme slowly attacked a lecithin suspension whereas ultrasonically treated lecithin was hydrolysed more rapidly. 3. Diethyl ether stimulated the hydrolysis of both the lecithin suspension and ultrasonically treated lecith...
