Effects of Atropine on Acetylcholine Overflow from Perfused Chicken Hearts

1978

Isolated chicken hearts were perfused (20 ml/min) with Tyrode’s solution. Release of acetylcholine (ACh) was evoked either by electrical stimulation (1 ms; 15 mA) of both preganglionic vagus nerves or by perfusion with dimethylphenylpiperazinium (DMPP). ACh was extracted from the perfusates by ion-pair extraction and determined by gas chromatography.

Alternative Methods of Sterilization in Dental Practices Against COVID-19

2020

SARS-CoV-2, and several other microorganisms, may be present in nasopharyngeal and salivary secretions in patients treated in dental practices, so an appropriate clinical behavior is required in order to avoid the dangerous spread of infections. COVID-19 could also be spread when patients touches a contaminated surface with infected droplets and then touch their nose, mouth, or eyes. It is time to consider a dental practice quite similar to a hospital surgery room, where particular attention should be addressed to problems related to the spreading of infections due to air and surface contamination. The effectiveness of conventional cleaning and disinfection procedures may be limited by seve…

New macrolactones from the defensive salivary secretion of soldiers of the african termite Pseudacanthotermes spiniger

1999

The salivary defensive secretion of large soldier termites of the species Pseudacanthotermes spiniger contains two novel macrocyclic lactones [22-keto-hexacosanolide (2) and 2-hydroxy-24-keto-octacosanolide (3)] together with the already known macrolactone hexacosanolide (1). In addition, the secretion contains important amounts of a polysaccharide based mainly upon β-glucopyranose, β-glucosamine and N-acetyl-β-glucosamine in equal amount.
