Denervation supersensitivity and the delay phenomenon. 1978

C B Cutting, and M C Robson, and N Koss

We have reviewed the denervation supersensitivity-AV shunt hypothesis (explaining the delay phenomenon) and assessed the contribution of each of the two components of denervation supersensitivy to delay. We concluded that adrenergic denervation supersensitivity contributes little to the delay phenomenon. We propose a new hypothesis, based on the effects of prolonged vascular smooth muscle relaxation in the precapillary arterioles, to explain the delay phenomenon.

UI	MeSH Term	Description	Entries
D008833	Microcirculation	The circulation of the BLOOD through the MICROVASCULAR NETWORK.	Microvascular Blood Flow,Microvascular Circulation,Blood Flow, Microvascular,Circulation, Microvascular,Flow, Microvascular Blood,Microvascular Blood Flows,Microvascular Circulations
D011941	Receptors, Adrenergic	Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction.

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.

D003042	Cocaine	An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.

D006085	Graft Survival	The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host.	Graft Survivals,Survival, Graft,Survivals, Graft
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001163	Arteriovenous Anastomosis	A vessel that directly interconnects an artery and a vein, and that acts as a shunt to bypass the CAPILLARY BEDS. Not to be confused with SURGICAL ANASTOMOSIS or ARTERIOVENOUS FISTULA.

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
