In some cases, P-450 isozymes catalyze the oxidative cleavage of P-O-aryl bonds (e.g., parathion, methyl parathion, fenitrothion, and diazinon) to form inactive water-soluble alkyl phosphates and aryl leaving groups that are readily conjugated with glucuronic or sulfuric acids and excreted.

From these in vivo and in vitro data, it is concluded that increase of the plasma beta-G level after OP administration is much more sensitive biomarker than cholinesterase inhibition to acute intoxication of OPs and carbamates.
The EG complex was easily dissociated by administration of OPs, i.e. fenitrothion, EPN, phenthionate, and bis-beta-nitrophenyl phosphate (BNPP), and resulting beta-G dissociated was released into blood, leading to the rapid and transient increase of plasma beta-G level with a concomitant decrease of liver microsomal beta-G level.

Sodium nitrite decreased the activity of glucose-6-phosphate dehydrogenase and vitamin E, with an increase of the activity of superoxide dismutase and protein SH groups and methaemoglobin level. fenitrothion caused similar changes as sodium nitrite and decreased the activity of choline esterase and the level of 2,3-diphosphoglyceric acid.

We estimated the reactivation rate with 2-PAM following inhibition of ChE by fenitrothion, methylparathion or ethylparathion using erythrocytes of rat and rabbit and rat brain.

The introduction of ultralow volume (ULV) application of the organophosphate pesticide Fenitrothion in grain terminals presents a risk to workers of skin contact with concentrate.
Blood testing, by the Ellman method, of a group of five grain terminal workers working on grain treatment showed a lowering of mean red blood cell cholinesterase (RBC ChE) activity to 23 units/gm Hb (normal value 28-40) with a range of 16-29.
