Hydrogen Sulfide

Electrochemical hydrogen sulfide biosensors.

The measurement of sulfide, especially hydrogen sulfide, has held the attention of the analytical community due to its unique physiological and pathophysiological roles in biological systems. Electrochemical detection offers a rapid, highly sensitive, affordable, simple, and real-time technique to measure hydrogen sulfide concentration, which has been a well-documented and reliable method. This...

Bronchodilatory Effect of Hydrogen Sulfide in Rat

Objective(s) The aims of present study were to elucidate the effect of NaHS as a H2S donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. Materials and Methods Tracheal rings from male adult Wistar rats were isolated and mounted in an organ bath containing Krebs–Henseleit solution under 1.5 g resting tension and contractions were recorded isom...

Biology for Physiological Hydrogen Sulfide

Hydrogen sulfide prodrugs—a review

Hydrogen sulfide (H2S) is recognized as one of three gasotransmitters together with nitric oxide (NO) and carbon monoxide (CO). As a signaling molecule, H2S plays an important role in physiology and shows great potential in pharmaceutical applications. Along this line, there is a need for the development of H2S prodrugs for various reasons. In this review, we summarize different H2S prodrugs, t...

Discrepant Tests for Hydrogen Sulfide.

Kligler and Triple Sugar Iron (TSI) media have been considered to be interchangeable for the purpose of detecting hydrogen sulfide production in the family Enterobacteriaceae. Contrary evidence is presented in this report. From various sources, 11 cultures were isolated which yielded a positive hydrogen sulfide reaction on Kligler medium and a negative reaction on TSI. Biochemically, these cult...
