Identification of dihydropteridine reductase in human platelets. | Normal human platelets were shown to contain the enzyme dihydropteridine reductase. The enzyme was not found in a variety of other cells of hematogenous origin. Partial purification and kinetic and physical data indicated that the platelet enzyme is similar to that previously characterized from liver. Dihydropteridine ... | 758,207 | [

Raphe inhibition of sympathetic preganglionic neurons. | Anatomical and electrophysiological studies suggest that the medullary raphe gives rise to a monosynaptic, inhibitory projection on sympathetic preganglionic neurons. Physiological and behavioral data indicate that this sympathoinhibitory pathway participates in the central control of cardiovascular function. | 758,687 | [
