[Usage of the Hoyer's medium for diagnostics and morphological studies of some parasites]

Various modification of the mixture of gum arabic with chloral hydrate can be used for mounting of small arthropods as well as some helminths. However, in diagnostic laboratories in Poland they seem to remain unknown. The authors of current work present examples of the Hoyer's medium application. The medium has been composed according to the initial, given by Hoyer, hundred-years-old recipe, which was the root of all other, later used recipes. Hoyer's medium is universal in action and very comfortable to use in slides for microscope investigation. It gives the immediate light-through effect, so it can be helpful in fast diagnostics. At the same time it allows to store the slides for a relatively long time e.g. with education purpose.
