1595894 Kumaran S, Tran-Minh C: Determination of organophosphorous and carbamate insecticides by flow injection analysis. Anal Biochem. 1992 Jan;200(1):187-94.

A flow injection system, incorporating an acetylcholinesterase (AChE) single bead string reactor (SBSR), for the determination of some organophosphorous (azinphos-ethyl, azinphos-methyl, bromophos-methyl, dichlorovos, fenitrothion, malathion, paraoxon, parathion-ethyl and parathion-methyl) and carbamate insecticides (carbofuran and carbaryl) is presented.

Three DNA-based genotyping techniques, bi-directional PCR amplification of specific allele (bi-PASA), single-stranded conformational polymorphism (SSCP) and minisequencing, have been developed and compared for the detection of the S291G (insensitive acetylcholinesterase) and L1014F (insensitive sodium channel) mutations associated with azinphos-methyl and permethrin resistance, respectively, in the Colorado potato beetle (Leptinotarsa decemlineata).

Cotton and synthetic knit glove fabrics in combination with an in vitro skin model were used to examine the capability of fabric to decrease the dermal absorption of the organophosphorus insecticides azinphos-methyl, paraoxon, and malathion.
Capability for inhibition of acetylcholinesterase was determined in samples of media taken from under the skin barrier after the skin model, with or without fabric protection, had been exposed to the test compounds for 4 h.

Both serum cholinesterase and PON1 activities were measured spectrophotometrically from 18 male agricultural workers who were chronically exposed to azinphos methyl, chlorpyriphos, or malathion and other pesticides during cereal spraying, transportation, and storage.

Values were simultaneously generated for the ED50 (milligrams per kilogram) for both cholinesterase and acetylcholinesterase.
Cholinesterase ED50 values roughly agreed with LD50 values for mevinphos, parathion, methyl parathion, and azinphos-methyl, but diazinon appeared much more inhibitory of blood than neuronal cholinesterase.

Toxogonin (80 mg/kg intraperitoneally) given 15 min. prior to the administration of organophosphorus insecticides dimethoate, malathion, parathion and azinphos-methyl, organophosphorus warfare agents soman and tabun, or carbamates physostigmine, pyridostigmine and aldicarb, reduced the toxicity in mice of these agents by increasing their LD50 dose 1.5-3 fold.
The acetylcholinesterase activity in erythrocytes, cerebrum and diaphragm of surviving mice 20 hours after organophosphate intoxication was similar both in toxogonin and P2S treated animals and untreated animals.

The toxicity of dimethoate, azinphos-methyl, diazinon, pirimiphos methyl, organophosphorus insecticides, and benomyl (a benzimidazole fungicide) singly and in mixture was studied in a human neuroblastoma cell line, SH-SY5Y.

An in vitro inhibition test was carried out with paraoxon and azinphos methyl oxon in order to investigate the role of equilibrium binding parameters (acetylcholinesterase/ organophosphorus compounds affinity) in determining susceptibility of the different species to parathion and azinphos methyl.

Several other photoproducts including trimethyl phosphate esters, which are known to be AChE inhibitors and 1,2,3-benzotriazin-4 (3H)-one as a member of triazine compounds were identified in photodegraded samples of malathion, malaoxon, and azinphos-methyl.

Incubations of azinphos-methyl suspensions and the in vitro epidermal systems covered with fabric indicated that both the epidermal cells and fabric provided protection against AChE inhibition caused by this OP and that the protective effects were additive, whether measured after 4 or 24 h of exposure.
