| Abstract: | The properties and distribution of enzyme droplets of kidney, liver, and gut of several vertebrates were investigated. Qualitative and quantitative differences in enzyme content existed in droplets from different sources. There was usually a closer correlation between the properties of the inclusions and their tissue origin than between the droplets of different organs obtained from one animal. The most noticeable specific characteristic was the relatively low acid phosphatase content of the lizard tissues. In all animals the enzyme droplets of liver and gut were considerably smaller than those of the proximal region of the nephron. The collecting ducts of bird and lizard kidneys possessed droplets of a different composition from those of the proximal segment, these bodies were considered to be associated with external secretion rather than with renal function. |
