Functional anticholinergic activity of drugs classified as strong and moderate on the anticholinergic burden scale on bladder and ileum.

Several medications are commonly administered to older Japanese patients. Since some of them have not been included in previously developed scales to estimate the anticholinergic burden, we have developed a new muscarinic receptor binding-based anticholinergic burden scale. This study aimed to investigate the functional inhibitory effects of 60 medications, classified as anticholinergic burden scales 3 and 2 by the anticholinergic burden scale, on muscarinic receptor-mediated contractions in the bladder and ileum.

Development of a pharmacological evidence-based anticholinergic burden scale for medications commonly used in older adults.

Aim: The present study aimed to develop a pharmacological evidence-based anticholinergic burden scale (ABS) through a direct assessment of muscarinic receptor-binding activities of 260 medications commonly used in older adults.

Methods: The muscarinic receptor-binding activities of 260 drugs were assessed by the displacement of specific [N-methyl- H]scopolamine methyl chloride binding in the rat brain. The maximum blood concentrations (C ) of drugs after their administration to subjects were cited from their interview forms.

Modulation of Vasomotor Function by Perivascular Adipose Tissue of Renal Artery Depends on Severity of Arterial Dysfunction to Nitric Oxide and Severity of Metabolic Parameters.

Perivascular adipose tissue (PVAT) enhances vascular relaxation of mesenteric arteries in SHRSP.Z-/IzmDmcr rats (SPZF), a metabolic syndrome model. We investigated and compared the effects of PVAT on the renal artery in SPZF with those on SHR/NDmcr-cp rats (CP).

Perivascular Adipose Tissue Compensation for Endothelial Dysfunction in the Superior Mesenteric Artery of Female SHRSP.Z-Leprfa/IzmDmcr Rats.

Regulation of arterial tone by perivascular adipose tissue (PVAT) differs between sexes. In male SHRSP.Z-Leprfa/IzmDmcr rats (SHRSP.

Lipoxin A Receptor Stimulation Attenuates Neuroinflammation in a Mouse Model of Intracerebral Hemorrhage.

Intracerebral hemorrhage (ICH) is caused by the rupture of blood vessels in the brain. The excessive activation of glial cells and the infiltration of numerous inflammatory cells are observed during bleeding. Thrombin is a key molecule that triggers neuroinflammation in the ICH brain.

Microglia-released leukotriene B promotes neutrophil infiltration and microglial activation following intracerebral hemorrhage.

Intracerebral hemorrhage (ICH) from blood vessel rupture results in parenchymal hematoma formation and neuroinflammation, ultimately leading to neurodegeneration. Several lines of evidence suggest that the severity of ICH-induced neural damage is exacerbated by infiltration of T-cells, monocytes, and especially neutrophils into the hematoma. Neutrophil migration is regulated by chemokines, formyl peptides, and leukotriene B (LTB), a metabolite of arachidonic acid.
