Diagnostic Difficulties

Hyperparathyroid (hypercalcemic) crisis develops with adenomas of the parathyroid glands or their hyperplasia, malignant non-endocrine tumors that secrete parathyroid hormone. The calcium level at which a crisis develops can be different. The clinical picture of the crisis is due to calcium intoxication and other symptoms and electrolyte disorders associated with it. It is very variable and therefore there are diagnostic difficulties. A differential diagnosis in this situation has to be carried out with comas of a different etiology, which have similar symptoms, with diseases of the cardiovascular system, respiratory system, gastrointestinal tract, kidney pathology and conditions caused by diseases of the neuropsychic sphere.

Acid Decomposition

In birds, urine enters the lower gastrointestinal tract from paired ureters and can be moved in a retrograde fashion into the colon and digestive ceca. As a major constituent of urine, uric acid is carried into these regions of the gastrointestinal tract. In these locations the chemical composition of the urine, including uric acid, could be altered. To examine this possibility the postrenal degradation of uric acid in the hindgut (ceca, colon, and ileum) of the Gambel quail (Callipepla gambelii) was investigated in vitro to determine the location of activity and the possible source of uricolytic enzymes. Significant breakdown of uric acid was observed in all cecal preparations; only minor amounts were degraded in the ileum and colon. The cecal degradation amounted to 15-49% of the uric acid estimated to be produced by the quail. Attempts to demonstrate uric acid decomposition by bacteria cultured from ceca gave inconclusive results.

Tract Function

Nanoparticles are increasingly popular in numerous fields including electronics, optics and medicine (vaccines, tissue engineering, microsurgery, genomics and cancer therapies). The most widely used nanoparticles in biomedical applications are those designed by man. Scientists have obtained many types of silica nanoparticles with defined shape and chemical composition, but different properties and applications. Nanoparticles include particles with at least one dimension ranging from 1–100 nm. Silica nanoparticles (Sn), reaching values from several dozen to several hundred m2/g, have unique physicochemical properties due to their porous structure and well-developed specific surface. Currently, the use of Sn in animal nutrition, with a focus on gastrointestinal tract function, is of great interest.
