A prospective study was performed (November 1998 to December 2003) to determine the prevalence of systemic hypertension (SH) in dogs with glomerular disease secondary to leishmaniasis. One hundred and five dogs with leishmaniasis were screened and staged for the presence of renal disease (RD) and SH. For the purpose of the study, RD was defined as serum(More)
In this paper we introduce prime fuzzy ideals over a noncommutative ring. This notion of primeness is equivalent to level cuts being crisp prime ideals. It also generalizes the one provided by Kumbhojkar and Bapat in [16], which lacks this equivalence in a noncommutative setting. Semiprime fuzzy ideals over a noncommutative ring are also defined and(More)
BACKGROUND Glomerular filtration rate (GFR) measurement is an indicator of kidney function. However, its usefulness in dogs at early stages of spontaneous chronic kidney disease (CKD) of glomerular origin, where routine laboratory techniques are not sufficiently sensitive, remains unproved. HYPOTHESIS That GFR is reduced in proteinuric nonazotemic or(More)
BACKGROUND Studies in dogs with experimental chronic kidney disease (CKD) have demonstrated that abnormalities of calcium-phosphorus (Ca-P) homeostasis occur frequently and have a negative effect on kidney function and survival. However, the prevalence of these alterations in dogs with naturally occurring CKD at different stages of severity has not yet been(More)
Sixteen dogs in which canine leishmaniasis (CL) was diagnosed by positive identification of Leishmania amastigotes in bone marrow samples were treated with a mixture of amphotericin B (AmB) desoxycholate in soybean oil. To prevent the toxicity of AmB, dogs were pretreated with saline (50 mL/kg) and mannitol (2 g/kg). Dogs were treated twice weekly with an(More)
Serum phosphorus concentrations were measured in 155 dogs with leishmaniosis at different stages of chronic kidney disease (CKD), and in 54 healthy dogs. CKD was classified into six stages, as follows: stage 0 (dogs with no evidence of CKD), serum creatinine (SCr) less than 125 micromol/l and urine protein:creatinine ratio (UPC) less than 0.2; stage 1A, SCr(More)
BACKGROUND Angiotensin-converting enzyme inhibitors (ACEIs) are currently used to control proteinuria in dogs with chronic kidney disease. Renal diets (RDs) have beneficial effects in the management of azotemic dogs, but its role in proteinuric non-azotemic (PNAz) dogs has been poorly documented. HYPOTHESIS Administration of a RD to PNAz dogs treated with(More)
