sudomotor การใช้

• The term IPSF represent a distinct subgroup of AIGA without sudomotor neuropathy or sweat gland failure.
• Quantitative sudomotor axon reflex testing ( QSART ) measures sweating response at local body sites to evaluate the small nerve fibers that innervate sweat glands.
• Similarly the release of cholinergic agents at sudomotor nerve terminals evokes an axon reflex that stimulates sweat glands inducing the body to sweat in response to heat.
• In the sympathetic nervous system the output connections mainly release noradrenaline, although acetylcholine is released at a few points, such as the sudomotor innervation of the sweat glands.
• "' Sudomotor innervation "'is the cholinergic innervation of the sympathetic nervous system prominent in sweat glands which causes perspiration to occur via activation of muscarinic acetylcholine receptors.
• One clinical test for the patient that can be performed is the QSART, or the Quantitative Sudomotor Axon Reflex Testing, which stimulates the autonomic nervous system of an individual by stimulating sweat glands through the promotion of axon reflexes.
• "' Idiopathic pure sudomotor failure "'( IPSF ) is the most common cause of a rare disorder known as acquired idiopathic generalized anhidrosis ( AIGA ), a clinical syndrome characterized by generalized decrease or absence of sweating without other somatic nervous dysfunctions and without persistent organic cutaneous lesions.
