Electrophysiological and histopathological evaluation of respiratory tract, diaphragm, and phrenic nerve after dichlorvos inhalation in rats.

The aim of this study was to investigate the dose-related effects of dichlorvos inhalation on electrophysiological alterations of diaphragm and phrenic nerve and the changes in the histologic structure of respiratory system. This study was performed on 33 rats divided into 5 groups, inhaling 1, 2, 5, 10, and 15 microg/L of dichlorvos, respectively. Electrodiagnostic investigations of diaphragm and phrenic nerve were made before and after inhalations.

Degradation of lignocellulose by extracellular enzymes produced by Thermomonospora fusca BD25.

Degradation products from the addition of extracellular enzymes from Thermomonospora fusca BD25 to ball-milled wheat straw, oat spelt xylan and solubilised kraft pulps were characterised by HPLC and TLC. Overall, a high percentage hydrolysis of oat spelt xylan (28.9%) occurred after 26 h incubation.
