Action of lisuride on reserpine-induced muscular rigidity in rats after local application into the striatum, ventricular space or the spinal subarachnoid space. 1982

C W Flosbach, and M Bräutigam, and R Dreesen, and H Herken

Muscular rigidity was induced in rats by reserpine (10 mg/kg) and the tonic activity of the gastrocnemic muscle was recorded in the electromyogram. Systemic administration of lisuride, an ergoline, resulted in a dose-dependent depression of rigidity. To examine the site of action of lisuride, we injected lisuride into the striatum, the ventricular space, and the spinal subarachnoid space of intact reserpinized rats. Lisuride is effective if injected into either the striatum or the spinal subarachnoid space, the spinal effect being more pronounced. These results suggest that the spinal cord is an important site of action of lisuride.

D009127 Muscle Rigidity Continuous involuntary sustained muscle contraction which is often a manifestation of BASAL GANGLIA DISEASES. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from MUSCLE SPASTICITY.

D012110 Reserpine An alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. Reserpine inhibits the uptake of norepinephrine into storage vesicles resulting in depletion of catecholamines and serotonin from central and peripheral axon terminals. It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use.
