Outcome after hydrogen sulphide intoxication.
AIM Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. METHODS The frequency and outcome of a large cohort of hydrogen sulphide intoxications is described. RESULTS From 198...
متن کاملHydrogen sulphide production by bacteria.
Hydrogen sulphide production by growing cultures and non-multiplying suspensions was compared and the factors influencing the sensitivity of the tests were investigated. Cysteine hydrochloride (0.01 yo) was added to Lemco broth to provide a medium with a standard source of sulphur. H,S was detected with lead acetate papers more readily than by lead acetate agar. Suspensions were tested with cys...
متن کاملFatal hydrogen sulphide poisoning in unconfined spaces.
Fatal hydrogen sulphide poisoning usually occurs in confined spaces. We report two fatal accidents in unconfined spaces. The first accident caused the death of three workers who entered an unconfined room in a silo of sludge at the same time that a truck dumped several tons of sludge from water purification stations. The hydrogen sulphide that had accumulated inside the silo spilled out into th...
متن کاملAn unrecognised form of hydrogen sulphide keratoconjunctivitis.
In 1988 six men were referred to St Paul's Eye Hospital after the onset of acutely painful, red eyes while at work at a local sausage casing factory. These patients prepared sheep intestine for sausage skin manufacture. Ocular examination showed bilateral blepharospasm, photophobia and lacrimation, intense conjunctival injection, and superficial punctate corneal erosions. There were no other ab...
متن کاملPeptide-based hydrogen sulphide-releasing gels.
An aromatic peptide amphiphile was designed for delivery of the signaling gas H2S. The peptide self-assembled in water into nanofibers that gelled upon charge screening. The non-toxic gel slowly released H2S over 15 hours, and the presence of H2S in endothelial cells was verified using a fluorescent H2S probe.
