AN APPARATUS TO FACILITATE HYDROGEN SULPHIDE PRECIPITATIONS.

An 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...

An Apparatus to Facilitate Intravenous Injections in the Mouse.

Exposure to hydrogen sulphide and respiratory function.

A study was carried out to assess possible effects of low concentrations of hydrogen sulphide on respiratory function. The cohort comprised 26 male pulp mill workers (mean age 40.3, range 22-60 years) with a daily exposure to hydrogen sulphide in the workplace, and 10 volunteers, who had asthma (three men, mean age 40.7, range 33 to 50 years, and seven women, mean age 44.1, range 31 to 61 years...

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...

Hydrogen 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...
