Severe organophosphorus or carbamate pesticide poisoning is an important clinical problem in many countries of the world. Unfortunately, little clinical research has been performed and little evidence exists with which to determine best therapy. A cohort study of acute pesticide poisoned patients was established in Sri Lanka during 2002; so far, more than 2000 pesticide poisoned patients have b...

Very few cases of the "intermediate neurotoxic syndrome", a type of neurotoxic effect or organophosphate compound have been reported in the literature. We are reporting a case that developed the clinical features of such type of neurotoxic effect after 55 hours of taking the organophosphorus compound.

Organophosphorus compounds (OPCs) have a wide variety of applications and are a serious threat for self-poisoning, unintentional misuse, terrorist attack, occupational hazard and warfare attack. The present standard treatment has been reported to be unsatisfactory. Many novel approaches are being used and tested for acute organophosphorus (OP) poison treatment. The bioscavenger concept captured...

Organophosphorus (OP) pesticides can be rapidly detected by integrating organophosphorus hydrolase with an optical leaky waveguide biosensor. This enzyme catalyses the hydrolysis of a wide range of organophosphorus compounds causing an increase in the pH. Thus, the direct detection of OP is possible by monitoring of the pH changes associated with the enzyme's activity. This article describes th...

lactose), and the formation of a " skin " (due to drying of protein on the surface, and not peculiar to milk). These changes are not of great importance as regards the infant. The next group consists of changes not appreciable by the ordinary observers, namely the precipitation of calcium, and alterations in the organic phosphorus compounds. The former renders the caseinogen less coagulable in ...

Antimitotic effects have been reported for several members of the class of compounds which may be described as the simple substituted phenols (Muhling et al., 1960, Hindmarsh 1951, Levan and Tjio 1948, Loveless and Revell 1949, Clowes 1951). Muhling et al. (1960) showed that complex derivatives such as the phenoxyalkyl acids exhibit an effect on mitosis similar to that of the phenols, and sugge...

The electroanalytical techniques of pulse polarography, stripping voltammetry and on-line electrochemical detection have been used for the identification and determination of trace concentrations of a wide variety of environmentally significant organic molecules, usually after the application of sample pretreatment procedures, certain separation techniques and, in some cases, derivatisation. Cl...

The effects of 0.001, 0.01, 0.1 and 0.5 ppm concentrations of malathion, an organophosphorus insecticide, viewed over the course of the experiment, on adult emergence and sex ratios of emerging adults of the parasitic wasp, Pimpla turionellae L. (Hymenoptera: Ichneumonidae) were investigated. Diets which contain 0.001 and 0.01 ppm malathion significantly increased the total adult emergence on d...
