On the receptors involved in the nervous control of salivary secretion by Nauphoeta cinerea Olivier. 1978

C R House, and R K Smith

1. It has been shown that the isolated salivary glands of Nauphoeta cinerea Olivier produce fluid secretion in response to nerve stimulation or bath applications of dopamine, noradrenaline, adrenaline and 5-HT. These catecholamines, of which dopamine is the most potent, evoked maximal responses matching that to nerve stimulation whereas 5-HT was less effective. 2. The receptors combining with 5-HT could be distinguished from those for the catecholamines and the transmitter at this salivary neuroglandular junction. 3. The results of experiments where glands were stimulated by dopamine in the presence of noradrenaline or adrenaline suggested that there are receptors with specific binding sites for dopamine. 4. The effects of several antagonists (Ginsborg, House & Silinsky, 1976) of the hyperpolarizing responses from acinar cells to nerve stimulation and the above agonists have been examined. Phentolamine reversibly suppressed the secretory responses to these stimuli whereas methysergide had no effect and ergometrine elicited fluid secretion in a dose-dependent manner.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.

D004837	Epinephrine	The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
