Objective
H2S may explain the dysregulation of microvascular tone associated with poor outcome following preterm birth. In adult vasculature, H2S is predominantly produced by CSE. We hypothesized that vascular CSE activity contributes to microvascular tone regulation during circulatory transition.
Methods
Preterm (GA62) and full‐term (GA69) guinea pig fetuses and neonates were studied. Microvascular...
A new method for the determination of hydrogen sulfide in hen tissues has been developed and validated. For estimation of hydrogen sulfide content, a sample (0.1 g) of hen tissue was treated according to the procedure consisted of some essential steps: simultaneous homogenization of a tissue and derivatization of hydrogen sulfide to its S‐quinolinium derivative with 2‐chloro‐1‐methylquinolinium tetrafluoroborate,...
