In order to further understand the role of the cholinergic anti-inflammatory pathway, the authors determined the effects of burn plasma from donor rats (DRs) on the microvascular circulation of healthy recipient rats and whether these could be altered by pretreatment with physostigmine (PT). DRs
Male Sprague-Dawley rats received LiCl (5 mEq/kg; sc) or saline 24 h prior to injection of cholinomimetics. Physostigmine (PHY, 0.54-0.80 mg/kg), diisopropylfluorophosphate (DFP, 1.3-2.5 mg/kg), pilocarpine (PIL, 23-30 mg/kg), or saline was injected subcutaneously at time 0. Rats were observed for
Microcirculatory dysfunction plays a pivotal role in the clinical development and manifestation of severe sepsis and as a marker for mortality. During this process, endothelial damage is characterized by structural and functional alterations that contribute to a great extent to tissue edema. Recent
SCH 29851 [8-chloro[6,11-dihydro-11-(1-carboethoxy-4-piperidylidene)- 5-H-benzo [5,6]cyclohepta[1,2-b]-pyridine] was discovered as part of a search for a new antihistamine without effects on the central nervous system (CHS). Antihistaminic potency and duration of action of SCH 29851 and other
In this retrospective series of 97 cases of manchineel fruit ingestion reported to French Poison Control Centers between 2009 and 2017, we investigated cases of poisoning due to manchineel fruit (from the Hippomane mancinella tree). This fruit is known to be responsible for oropharyngeal and
The pulmonary and systemic vascular beds differ in their response to several vasoactive substances. Acetylcholine (ACh) is a potent systemic vasodilator; however, its effects on the pulmonary circulation are not clear. Utilizing the isolated rabbit lung preparation perfused in situ under constant
Atropine, an anticholinergic agent commonly used in human and veterinary medicine, is reported to cause toxicity associated with its antimuscarinic action. A juvenile pygmy sperm whale, Kogia breviceps, was treated with atropine in an attempt to relieve symptoms similar to pyloric stenosis, as has
