The aim of this work was to study cross-reactivity in the diagnosis of two related ascaridosis. Nineteen patients diagnosed with recidivous acute urticaria (RAU) caused by Anisakis simplex and 26 patients diagnosed with visceral larva migrans (VLM) caused by Toxocara canis were studied employing commercial diagnostic kits and "in house" assay kits. Cross-reactivity observed was greater when usi...

Many accessory lacrimal glands can be found along the inner surface of the eyelids. A variable number of thin-walled excretory ducts, blood vessels, lymphatics, and nerves pass from the main orbital gland into these accessory lacrimal glands. The ducts continue downward, and about 12 of them empty into the conjunctival fornix approximately 5 mm above the superior margin of the upper tarsus. Bec...

In 1895, Hopkins described the white and yellow wing pigments of Pieridae as ' . . .excretory substances which function in ornament...' (Hopkins, 1895). ^ those days, it was generally recognized that purines, especially uric acid, were excretory products. Hopkins thought that the white substance was uric acid and that the yellow one was a derivative. In 1925 Wigglesworth still believed the wing...

In patients with end-stage renal disease (ESRD), the intestinal tract may assume an accessory potassium (K) excretory role in the face of declining renal excretory function. Here, we report the case of a patient with ESRD who developed severe hyperkalemia following ileostomy not colostomy. A 6△-year-old woman undergoing hemodialysis began developing severe hyperkalemia after ileostomy. Previous...

A study of the cross-reactivity among somatic and excretory-secretory antigens of the third stage larvae of Anisakis simplex s.l. and somatic antigens of other ascarid nematodes (Ascaris lumbricoides, A. suum, Toxocara canis, Anisakis physeteris, Hysterothylacium aduncum and H. fabri) was carried out by immunoblotting. It was revealed a high degree of cross-reactivity among ascarids in the 30 a...

Excretory organs were acquired in the early phase of metazoan evolution, and they play a crucial role in the maintenance of homeostasis of body fluids. In general, these organs consist of two functional components, the primary-urine producing apparatus and the modulating tubule. This basic organization of the excretory organs is conserved among most metazoans. Herein, we present an overview of ...

1. The chemical mediator of renal hypertension is rapidly destroyed by the metabolic activity of the normal kidney. The excretory function of the kidney plays little, if any, rôle in eliminating the mediator of hypertension. 2. If specific substances are responsible for the uremic syndrome, they are neither produced nor eliminated to any significant extent by the metabolic activity of the kidne...

The Caenorhabditis elegans excretory cell extends tubular processes, called canals, along the basolateral surface of the epidermis. Mutations in the exc-5 gene cause tubulocystic defects in this canal. Ultrastructural analysis suggests that exc-5 is required for the proper placement of cytoskeletal elements at the apical epithelial surface. exc-5 encodes a protein homologous to guanine nucleoti...
