Effects of Chlorpromazine on Some Motor Reflexes*~-
-The effects of chlorpromazine (CPZ) on the patellar reflex and segmentally evoked spinal cord potentials were determined in various cat preparations. CPZ in doses of I-8 mg/kg given intravenously (as an accumulative dose) produced a signiticant depression of the patellar reflex and segmentally evoked potentials in animals with an intact central nervous system. Hypotension, potentiation of anes...
متن کاملEffect of diabetes on some primitive reflexes.
Primitive reflexes (PRs) are present in newborns; they disappear as the brain matures and increase in frequency in healthy elderly individuals. Primitive reflexes are more frequent in some neurological disorders than in age-matched controls. The aim of this study was to investigate the effect of diabetes on some PRs. We examined three PRs (glabellar tap, snout and palmomental reflexes) in 376 s...
متن کاملSome Characteristics of Certain Reflexes
Records are presented which have been obtained from man by direct intra-arterial catheterization and electrocardiography. These records have been selected (1) because they offer evidence for the validity of Starling's law in intact man and (2) because they demonstrate that when the heart is influenced by activity of the so-called "intrinsic" reflexes these manifestations of Starling's law are m...
متن کاملVagal cardiopulmonary reflexes after total cardiac deafferentation.
BACKGROUND There are conflicting data regarding whether the primary source of afferent input for the vagal cardiopulmonary reflex emanates from receptors located in the ventricles, atria, and/or lungs. This study evaluated the effects of total cardiac deafferentation on the reflex control of efferent renal sympathetic nerve activity (RSNA) in response to a stimulus that affected all vagal recep...
