Urological complications of regional enteritis occur frequently and may be clinically unsuspected. Radiographic findings include nephrolithiasis, characteristic stricture of the ureter, panvesiculitis, and enterovesical fistual. Less specific findings include renal amyloidosis and retroperitoneal abscesses. Mucosla nodularity of the bladder dome, even without gastrointestinal symptoms, should raise the possibility of regional enteritis. On the other hand, occult ureteral stenosis in patients with known regional enteritis may be present. For this reason, it is recommended that routine and periodic excretory urograms be a central part of the evaluation of the patient with regional enteritis.

The toxicity of melamine has attracted much attention since the outbreak of nephrolithiasis among children ingesting melamine-contaminated infant formula in China. However, there is little knowledge about the molecular mechanisms underlying the melamine-induced toxicity. In this paper, a ligand-protein docking method (INVDOCK) was applied to predict the toxicity-related target proteins for melamine and its metabolite, cyanuric acid. As a result, 23 and 35 proteins were finally identified as the potential target proteins for melamine and cyanuric acid, respectively. Through an enrichment analysis, it was found that nephrotoxicity and lung toxicity might be the most significant toxicities induced by melamine and cyanuric acid. Four target proteins (glutathione peroxidase 1, beta-hexosaminidase subunit beta, L-lactate dehydrogenase and lysozyme C) may be related to the molecular basis of the nephrotoxicity induced by melamine except for known kidney crystals formation. After mapping all these toxicity-related target proteins onto cellular pathways, it was indicated that the toxicities of melamine and cyanuric acid might also be caused by breaking down redox balance, perturbing the arginine and proline metabolism and damaging the homeostasis of energy production system. To further explore the mechanisms underlying the toxicities of melamine and cyanuric acid, a biological signal cascades network constructed by some of the toxicity-related target proteins was discussed.

This review article is written to describe the results of ultrasonography of the kidneys in healthy camels as well as camels with some renal disorders. In the dromedary camel, the physiology of the kidney is of interest in view of the specialization of the camel to hot dry deserts and to prolonged periods without water. It plays an important role in water conservation through the production of highly concentrated urine that may predispose animal to varieties of renal disorders. Examples of kidney affections in dromedary camels are renal capsular pigmentation, medullary hyperemia, subcapsular calcification, cortical and medullar discoloration, hemorrhage in renal pelvis, nephrolithiasis, and hydatidosis. Congestion, hemorrhage, hydronephrosis, acute glomerulonephritis, subacute glomerulonephritis, chronic glomerulonephritis, diffuse interstitial nephritis, focal interstitial nephritis, renal cyst, hyaline degeneration, renal amyloidosis, tubular nephrosis, pyelonephritis, hemosiderosis, and renal toxicity. When the kidney is examined by ultrasonography, the clinician can get sufficient information about the size, position, and echo patterns of the renal cortex and medulla and renal pelvis and outlines of the renal blood vessels. In recent years, ultrasonography has been used in camels for scanning of the healthy status as well as evaluation and determining the diagnosis and prognosis of diseased cases. Examples of diseases evaluated by ultrasonography are paratuberculosis, trypanosomiasis, pneumonia, pleurisy, gastrointestinal neoplasms, chronic peritonitis, splenic abscessation, and hepatic disorders. Of the renal disorders assessed by ultrasonography are nephrolithiasis, hydronephrosis, pyelonephritis, renal abscessation, and renal neoplasms. Ultrasound guidance in biopsy of renal specimens has also been reported in dromedary camels.
