The Picric-Acid-Schiff's (PAS) reaction in the urinary bladder epithelium in hyrax, by J. Epelu-Opio, Zambia Journal of Science & Technology, Vol.2, no.3, July 1977, Pg. 5-10.


Sections of the wall of the urinary bladder of the rock hyrax [Order: Hyracoidea] were stained by PAS reaction technique either prior to or after treatment in diastase solution. The component cell layers of this transitional epithelium showed differences in the degree of their sensitivity to the PAS reaction. The PAS-positive material in the epithelial cells was digested by diastase. The fixative used in the initial preparatory stages produced some variations with regard to the reaction of the epithelial cells of the PAS reaction.
