Photochemical tests were used to discriminate between photoallergens and photoirritants. UV absorption spectrometry was employed to identify chemicals that absorbed sunlight wavelengths and which required further testing. Photoallergic potential was assessed by studying photobinding of the test...
The notification procedure of the European Union (EU) for new chemicals requires the application of protocols on physicochemical and toxicological tests for the evaluation of physicochemical properties and probable toxic effects of each notified substance. A computerised database was developed...
Procedures have been established and tested for the extension of a decision support system (DSS) for the prediction of the local irritation/corrosion potential of chemicals by using self-learning classifiers. The different approaches (decision trees, distances examinations in a multidimensional...
The aim of this study was to examine whether the isolated perfused bovine udder could be used as a suitable in vitro inflammation model. A common in vivo inflammation model is arachidonic acid-induced inflammation in mouse ears. As an in vitro substitute for this model, arachidonic acid was...
The effects of two different keeping systems on the humoral immune response and productivity were compared for 80 laying hens, divided into four groups. Two groups, each of 20 hens, were kept on the ground and two were kept in cages. All the birds were immunised subcutaneously with human serum...
