Acompanhamento laboratorial da função renal de cães sadios tratados experimentalmente com doses terapêuticas de anfotericina B

O presente trabalho objetivou avaliar a função renal de dez cães adultos saudáveis submetidos à administração de doses terapêuticas do antifúngico anfotericina B, cuja utilização tem sido limitada pelo seu elevado potencial nefrotóxico, e avaliar o método laboratorial mais sensível e precoce de diagnóstico de lesão renal. Foram realizadas, diariamente, urinálise, excreção fracionada de sódio e potássio, dosagem sérica de creatinina e uréia e atividade urinária de gama-glutamiltransferase (GGT). Concluiu-se que a anfotericina B provoca lesões nos túbulos proximal e distal, induzindo acidose tubular renal do tipo I e Diabetes insipidus nefrogênico em cães. Avaliação da função renal, preferencialmente por dosagens de creatinina, uréia e potássio séricos, é recomendada antes de cada aplicação do fármaco. A densidade urinária foi o parâmetro mais precocemente alterado pela lesão renal. A GGT urinária não foi eficaz para o diagnóstico precoce de lesão induzida por anfotericina B.

Efeitos do fentanil, droperidol e inoval sobre função renal e eletrólitos (sódio e potássio)

The influence of Fentanyl, Droperidol and Innovar on renal function and electrolytes (sodium and potassium) were studied on 18 dogs. Fentanyl disturbs kidney function and decreases plasmatic potassium. Droperidol and Innovar do not disturb the main renal function but decrease plasmatic potassium. The results obtained point out the importance of associate employment of Fentamyl and Droperidol, since the latter seems to establish the renal disorders occasioned by Fentanyl, probably owing to its adrenergic α blocking action.

Avaliação tardia da função renal em doentes com paracoccidioidomicose tratados com anfotericina B por meio da determinação do ritmo de filtração glomerular com EDTA Cr51

A late survey of the renal function was performed in eighteen patients with paracoccidioidomycosis treated with amphotericin B, according to the glomerular filtration rate (RFG). The method was compartment analysis by single injection using EDTA Cr51, determined by its 'half biological life' and dosages of blood urea nitrogen and creatinine. The patients were seventeen males and one female. They were from 22 to 76 years old. Ten of these patients received 2 g of amphotericin B and eight of them received 4 g. There were no expressive difference between the two groups, taking into account age, dose in mg/kg of weight/day, time of conclusion of the treatment, urea, creatinine, glomerular filtration was smaller than the normal, and average of the half biological life of the EDTA Cr51 was large than the normal. The achieved results permitted us to consider that the amphotericin B determines deficit of renal function. However, by the present study, it hasn't been possible to affirm if the modifications are definitive.

Efeitos do extrato aquoso de cebola (Allium cepa L.) sobre a função renal e a pressão arterial em ratos Wistar

The vegetal species, Allium cepa, known as onion, is widely used in the folk medicine as diuretic, besides it has been used on the bronchitis, cough, cardiovascular diseases and hypertension treatment. In this study we evaluate the onion aqueous extract (AE) effect on water flow and electrolytes in anesthetized Wistar rats, besides we also evaluate arterial pressure alterations. Two groups were studied: Group 1 (control) - oral tratment with 1.0 mL of distilled water, and Group 2 (experimental) - oral treatment with 1.0 mL of AE 20%. The rats were anesthetized and we canulate the trachea, left carotide artery (for arterial pressure measurement and blood collecting), jugular vein (to execute inulin perfusion - to register glomerular filtration), and urinary bladder (to collect urine). The Group 1 results had shown that the animals had not presented significant alterations (p>0.05) in the analyzed parameters. The animals of Group 2 had a significant reduction (p<0.05) in the arterial pressure (22.0%). However, there were not significant alterations in renal parameters (p>0.05). These results show that the treatment with the AE lead a hypotensor effect in anesthetized Wistar rats, but not followed by renal parameters alterations.

Efeitos da ciclosporina a sobre a função renal de cães da raça Golden Retriever normais ou afetados pela distrofia muscular

The muscular dystrophy of Golden Retriever is a degenerative miopaty caused by the absence of dystrophy and it is genetically homologue of the Duchenne muscular dystrophy in humans, so, these dogs are considerably experimental models for studies on cellular therapy. Their successful depends of the adequate immunosuppression. Cyclosporin A is indicated for that and the monitoring of blood concentration and adverse effects are essential to viabilise the therapy. It was studied GRMD dogs, and normal dogs from the same breed, submitted for therapy with CsA, associated, on GRMD, of cell transplantation. It was evaluated the possible effects of the drug on renal functions. It has been considerate the clinic manifestations, urinalisis, testis of glomerular function and blood concentrations of urea, cretinine, sodium and potassium. In our results we found a discrete increase of blood urea on booth groups; increased levels of urine's cylinders and protein and also increase of urinary density on GRMD group. CsA therapy could make acute lesions on renal tubules, especially on GRMD. These dogs also have different reactions than normal dogs on relation of ions homeostasis and renal function. However, earlier diagnosis and adequate treatment could prevent the development of renal diseases.

Parâmetros bioquímicos de avaliação da função renal e hepática de equinos com cólica submetidos a laparotomia, sobreviventes ou não

We examined 46 adult horses - six healthy, as control, (group 1) and 40 horses with colic submitted to treatment by laparotomy. Twenty animals had no postoperative complication (group 2), and twenty died or were euthanized from seven to ten days after the surgery (group 3). There was an increase in serum urea and creatinine concentration and AST, FA and GGT activity of animals from group 1 and group 2, indicative of renal and hepatic injury. The changes were associated with dehydration and endotoxins. Depending on the severity of the colic, animals may develop kidney and liver failure.
