Bone marrow cytological evaluation in dogs with chronic kidney disease
Provedor de dados: 45
Autores: Borin-Crivellenti,S.; Crivellenti,L.Z.; Carvalho,M.B.; Santana,A.E.
Since anemia is indicated as an important compromising factor for the quality of life of dogs with chronic kidney disease (CKD), bone marrow cytological analysis may provide more information on the hematological profile these dogs and, therefore, allow clinicians to not only choose the most adequate treatment but also monitor the response to therapy. The aim of this study was to investigate the feasibility with sternal bone marrow puncture in chronic kidney disease (CKD) using only local anesthesia and check if the cytological analysis is helpful to determine the hematological status. We found that erythroid hypoplasia occurred only in terminal CKD patients, and that the bone marrows of dogs with CKD stages 2 and 3 were quantitatively similar to those of...

Crocus sativus, known as saffron, is used in folk medicine for treatment of different types of diseases, and its anti-inflammatory and free radical scavenging activities have been demonstrated. The present study evaluated gentamicin nephrotoxicity in saffron treated rats. Male Wistar rats (200-250g) were treated with saffron (40 or 80 mg/k/d) for 10 days, or saffron (40 or 80 mg/ kg/d) for 10 days and gentamicin 80 mg/kg/d for five days, starting from day 6. At the end of treatment, blood samples were taken for measurement of serum creatinine (SCr) and BUN. The left kidney was prepared for histological evaluation and the right kidney for Malondialdehyde (MDA) measurement. Gentamicin 80 (mg/k/d) increased SCr, BUN and renal tissue levels of MDA and induced...

Renal involvement in leprosy: retrospective analysis of 461 cases in Brazil
Provedor de dados: 55
Autores: Silva Júnior,Geraldo Bezerra da; Daher,Elizabeth De Francesco.
BACKGROUND: Renal lesions in leprosy have been extensively described, including amyloidosis, glomerulonephritis, nephrosclerosis, tubulointerstitial nephritis and granulomas. MATERIAL AND METHODS: A retrospective study was designed to detect renal function abnormalities in 461 leprosy patients, without any co-morbidity, seen in a university hospital in northeast Brazil. The laboratory test results concerning renal function were examined in the patients' medical records. RESULTS: The mean age was 39 ± 18 years and 217 (47%) were male. The mean duration of disease was 21 ± 38 months. Levels of creatinine above 1.4mg/dL had been detected in 40 patients (8.6%). The levels of creatinine and urea were higher in lepromatous leprosy patients. Proteinuria,...

alpha-Smooth muscle actin and proliferating cell nuclear antigen expression in focal segmental glomerulosclerosis: functional and structural parameters of renal disease progression
Provedor de dados: 56
Autores: Geleilete,T.J.M.; Costa,R.S.; Dantas,M.; Coimbra,T.M.
The aim of the present study was to investigate the expression of alpha-smooth muscle actin (alpha-SM-actin) and proliferating cell nuclear antigen (PCNA) in renal cortex from patients with focal segmental glomerulosclerosis (FSGS) and their correlations with parameters of renal disease progression. We analyzed renal biopsies from 41 patients with idiopathic FSGS and from 14 control individuals. The alpha-SM-actin immunoreaction was evaluated using a score that reflected the changes in the extent and intensity of staining in the glomerular or cortical area. The PCNA reaction was quantified by counting the labeled cells of the glomeruli or renal cortex. The results, reported as median ± percentile (25th; 75th), showed that the alpha-SM-actin scores in the...

Comparative study of IgA nephropathy with and without crescents
Provedor de dados: 56
Autores: Bitencourt-Dias,C.; Bahiense-Oliveira,M.; Saldanha,L.B.; Barros,R.T.; Woronik,V.
Glomerular crescents were analyzed as a prognostic factor in retrospectively reviewed data from 144 patients with biopsy-proven IgA nephropathy. Crescents were found in 26 (18%) patients, and detected in 2 to 100% of glomeruli in each specimen. In 5% of the patients more than 50% of the glomeruli were affected. Thirty patients with IgA nephropathy without crescents were studied as a control group. Mean age was 30.3 ± 9.4 and 30.2 ± 12.0 years for the patients with and without crescents, respectively, and males prevailed in both groups. The length of follow-up was 23.2 ± 41.6 months for patients with crescents and 29.3 ± 35.3 months for patients without crescents. Eighty percent of the patients with crescents were hypertensive, compared to 27% of the...

Response of the growth plate of uremic rats to human growth hormone and corticosteroids
Provedor de dados: 56
Autores: Barbosa,A.P.F.; Silva,J.D.P.; Fonseca,E.C.; Lopez,P.M.; Fernandes,M.B.C.; Balduino,A.; Duarte,M.E.L.
Children with chronic renal failure in general present growth retardation that is aggravated by corticosteroids. We describe here the effects of methylprednisolone (MP) and recombinant human growth hormone (rhGH) on the growth plate (GP) of uremic rats. Uremia was induced by subtotal nephrectomy in 30-day-old rats, followed by 20 IU kg-1 day-1 rhGH (N = 7) or 3 mg kg-1 day-1 MP (N = 7) or 20 IU kg-1 day-1 rhGH + 3 mg kg-1 day-1 MP (N = 7) treatment for 10 days. Control rats with intact renal function were sham-operated and treated with 3 mg kg-1 day-1 MP (N = 7) or vehicle (N = 7). Uremic rats (N = 7) were used as untreated control animals. Structural alterations in the GP and the expression of anti-proliferating cell nuclear antigen (PCNA) and...

Influence of acute renal failure on the mononuclear phagocytic system
Provedor de dados: 56
Autores: Sousa,V.R.A.; Sousa,A.A.; Petroianu,A.; Simal,C.J.R.; Barbosa,A.J.A.
Several studies show the ability of macrophages to remove particles injected into the bloodstream. This function seems to be increased in the presence of acute renal failure. The objective of the present study was to assess the phagocytic function of the main organs (spleen, liver and lung) of the mononuclear phagocytic system in renal and postrenal failures. Fifteen rats (250-350 g) were divided into three groups (N = 5): group I - control; group II - ligature of both ureters, and group III - bilateral nephrectomy. On the third postoperative day, all animals received an iv injection of 1 ml/kg 99mTc sulfur colloid. Blood samples were collected for the assessment of plasma urea, creatinine, sodium, and potassium concentrations and arterial gasometry....

Ionic radiocontrast inhibits endothelium-dependent vasodilation of the canine renal artery in vitro: possible mechanism of renal failure following contrast medium infusion
Provedor de dados: 56
Autores: Discigil,B.; Evora,P.R.B.; Pearson,P.J.; Viaro,F.; Rodrigues,A.J.; Schaff,H.V.
To determine if radiocontrast impairs vascular relaxation of the renal artery, segments (4-5 mm in length) of canine renal artery were suspended in vitro in organ chambers to measure isometric force (95% O2/5% CO2, at 37ºC). Arterial segments with and without endothelium were placed at the optimal point of their length-tension relation and incubated with 10 µM indomethacin to prevent synthesis of endogenous prostanoids. The presence of nonionic radiocontrast (iohexol, Omnipaque 350, 1 ml in 25 ml control solution, 4% (v/v)) did not alter endothelium-dependent relaxation to acetylcholine in rings precontracted with both norepinephrine and prostaglandin F2alpha (N = 6). When the rings were precontracted with prostaglandin F2alpha, the presence of ionic...

Renal dysfunction in patients with sickle cell anemia or sickle cell trait
Provedor de dados: 56
Autores: Sesso,R.; Almeida,M.A.; Figueiredo,M.S.; Bordin,J.O.
Patients with sickle cell anemia (Hb SS) or sickle cell trait (Hb AS) may present several types of renal dysfunction; however, comparison of the prevalence of these abnormalities between these two groups and correlation with the duration of disease in a large number of patients have not been thoroughly investigated. In a cross-sectional study using immunoenzymometric assays to measure tubular proteinuria, microalbuminuria, measurement of creatinine clearance, urinary osmolality and analysis of urine sediment, we evaluated glomerular and tubular renal function in 106 adults and children with Hb SS (N = 66) or Hb AS (N = 40) with no renal failure (glomerular filtration rate (GFR) &amp;gt;85 ml/min). The percentage of individuals with microalbuminuria was...
