The aim of the present study was to establish whether, in terminal arterioles from the rat cremaster, acetylcholine (ACh) elicits nitric oxide (NO)-independent dilation corresponding to the transient ACh-induced endothelium-dependent hyperpolarization described in arteries. For this purpose, the responses of terminal arterioles [mean diam 15.0 +/- 0.4 (SE) microns] were studied by intravital microscopy in rat cremaster muscle. During 15 min of superfusion by 10(-5) M ACh, the response was… 
Pentobarbital-sensitive EDHF comediates ACh-induced arteriolar dilation in the hamster microcirculation.
TLDR
It is suggested that a considerable part of the ACh dilation in the microcirculation is mediated by EDHF, which also contributes to the control of basal tone in conscious animals and supports the idea that "microcirculatory" EDHF is a product of the cytochrome P-450 pathway.
Anesthetics alter relative contributions of NO and EDHF in rat cremaster muscle microcirculation.
TLDR
The data suggest that anesthetics can alter the balance between NO and ED HF vasodilation in the microcirculation and that NO-dependent mechanisms are enhanced and EDHF action inhibited during isoflurane anesthesia.
Vascular reactivity in mesenteric resistance arteries following chronic nitric oxide synthase inhibition in Wistar rats
TLDR
Chronic NOS inhibition results in a down‐regulation of the contractile responses to KCl and phenylephrine in mesenteric resistance arteries, despite an increase in medial cross sectional area, and also the contraction in response to protein kinase C activation.
Acute hyperglycemia depresses arteriolar NO formation in skeletal muscle.
TLDR
Results indicated that in the rat spinotrapezius muscle, acute hyperglycemia suppressed arteriolar NO production while simultaneously augmenting vascular smooth muscle responsiveness to nitroprusside, presumably through cGMP-mediated mechanisms, which may have allowed ACh- and muscle contraction-induced vasodilation to be maintained during hyper glycemia despite an impaired NO system.

Nitric oxide produced via neuronal NOS may impair vasodilatation in septic rat skeletal muscle.
TLDR
It is concluded that AG and SMT inhibit nNOS activity in sepsis skeletal muscle, NO could impair vasodilative responses in control and septic rats, and the source of increased endogenous NO in septic muscle is likely upregulated nN OS rather than iNOS.
Alterations in Reactivity of Small Arterioles in Rat Skeletal Muscle as a Result of Chronic Ischaemia
TLDR
Impaired dilation, most likely due to endothelial dysfunction, is an early manifestation of altered reactivity in the microcirculation of chronically ischaemic muscles, with functional impairment of vascular smooth muscle as a later consequence.
Role of Na+ lK* ATPase on the Relaxation of Rabbit Ear and Femoral Arteries
TLDR
The results suggest that Nar/Ki ATPase might play a role in the relaxation of ear and femoral aiteries to nitrovasodilators, to potassium channel openers and to activation of histamine receptors, and that Na+7K+ ATPasemight play a roles in the cholinergic relaxation ofEar, but not femoral arteries, suggesting that the mechanism of cholin allergic relaxation might differ in each type of artery.
