The labour market, occupational safety and health, and work organisation are our main fields of activity. The creation and use of knowledge through learning, information and documentation are important to the Institute, as is international cooperation. The Institute is collaborating with interested parties in various development projects. The areas in which the Institute is active include: • la...

A case of propylene glycol poisoning is described in a 39 year old woman which resulted in her admission to hospital in status epilepticus. She had had a long-standing history of uncontrollable epilepsy. The diagnosis of propylene glycol poisoning resulted directly from the finding of a high plasma osmolal gap on admission. This finding would have been missed if later samples only had been anal...

We tested the hypothesis that the solvent for etomidate was a factor in the incidence of pain and other side effects after injection, and that these were associated with histamine release. Nine of 10 volunteers who received etomidate in a propylene glycol formulation reported moderate to severe pain on injection; only one of 10 subjects who received a lipid emulsion formulation reported mild pa...

Concentrated aqueous cornstarch (CS) suspensions are often used to demonstrate an extreme example of shear thickening rheological behaviour. Here, we describe the increased rheological complexity that occurs on the addition of poly(propylene glycol) 10 (PPG) to an aqueous CS suspension. The appearance of shear thickening/jamming, shear thinning, yield stress and near-Newtonian behaviours is dep...

Four polyesters were prepared by stepwise condensation of isopbthalic acid, cblorendic acid and maleic anhydride with propylene glycol using p-toluenesulpbonic acid as catalyst and xylene as entrainer. The quantities of maleic anbydride and propylene glycol used were 1 and 2.2 moles respectively and tbe molar ratios of cblorendic acid to isopbtbalic acid were 0.2: 0.8. 0.4: 0.6, 0.6: 0.4 and 0....

Introduction Debridement of devitalised tissue is essential for successful wound healing, as formation of granulation tissue requires a clean wound bed. Devitalised tissue that may have an imbalance of bacteria may retard the healing process. Amorphous hydrogels are primarily designed to promote autolytic debridement of devitalized tissue. Hydrogels contain polymers, or gelling agents that infl...

Solubility of lornoxicam in various pure solvents and solvent-cosolvent mixtures was studied to understand drug vehicle interactions and in order to get the required solubility equal to the dose of lornoxicam, i.e., 4 mg/ml for development of solution formulation. Polyethylene glycol (PEG) 400, propylene glycol, ethanol, water, dimethyl formamide, dimethyl sulfoxide, and ethyl acetate were used...

Attraction of oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), and nontarget insects to preservative fluids ethylene glycol antifreeze, propylene glycol antifreeze, or mineral oil in bucket traps that contained captured decaying male oriental fruit flies, a male lure (methyl eugenol), and a toxicant (DDVP vapor insecticidal strip) were compared with dry control traps. Si...

SummaryWhile the freezing techniques of mammal embryos have been providing promising results, the cryopreservation of teleostean eggs and embryos have remained unsuccessful up to now. Therefore, this work aimed to develop a procedure of cryogenic preservation of embryos of Prochilodus lineatus and to observe, at both structural and ultrastructural levels, the morphological alterations that took...
