THE EXCRETORY SYSTEM IN DIGENEA. II

Excretory Urography in Dogs a Nd Cats. Ii. Urinary Diseases

Excretory urography using sodium diatrizoate was performed in 144 dogs and in 14 cats clinically suspects of having urinary disorders. The purpose of the present study' is to evaluate at which time following the injection of the contrast mediun, the radiographic alterations were better visualized, making possible the diagnosis of these disorders. In this study the best visualizations were found...

The Functional Design of the Insect Excretory System

Insects have a slowly operating excretory system in which the passive rate of movement of haemolymph solutes into a slowly secreted primary excretory fluid is restricted by a reduction in the area available for passive transfer. They may have come to possess such an energy-saving system as a result of their evolution as small animals in osmotically and ionically stressful environments. Although...

A mucosal IgA-mediated excretory immune system in vivo.

The capacity of mucosal IgA Abs to serve as an excretory immune system in vivo was investigated. Mice expressing a transgenic TCR were immunized intragastrically with the cognate Ag to elicit a vigorous mucosal IgA Ab response. Soon after i.v. challenge, Ag was detected within the epithelial cells of the small intestinal crypts and to a lesser degree within the epithelial cells higher up the vi...

Lacrimal excretory system sequelae in patients treated for leishmaniasis.

UNLABELLED Leishmaniasis infection may involve destruction of nasal tissues resulting in lacrimal drainage system alteration. PURPOSE To evaluate the frequency of lacrimal excretory system sequelae in patients treated for leishmaniasis. METHODS Forty-five leishmaniasis-treated patients (90 nasolacrimal ducts) were submitted to lacrimal excretory system evaluation. All were evaluated by Jone...
