Histochemical observations on the mycetomes of Pyrilla perpusilla Walker.
Histochemical studies of mycetomes and mycetocytes of Pyrilla perpusilla show PAS positive material, what can suggest the presence of glycogen. The mycetocytes failed to stain with alcian blue and methyl green pyronin "Y" indicating the absence of mucopolysaccharides and RNA respectively. The mycetocytes show positive congo red. Millon and Mercury bromophenophenol blue staining thereby proving that they contain glycoprotein, tyrosine and proteins. Positive reaction with Sudan black may show the presence of lipids and lipoproteins.
