ABSTRACT

Relatou-se um caso de fibrossarcoma localizado na uretra média de uma cadela, sem raça definida, que apresentava sinais de polaquiúria, estrangúria e hematúria no início da micção. O animal também apresentava poliúria, polidipsia, êmese e anorexia há dois dias. Os exames complementares levaram ao diagnóstico de hidronefrose bilateral, hipoplasia renal direita e massa em uretra causando dilatação dorsal de sua porção média. A biópsia não foi realizada antemortem devido ao estado geral do paciente, que, mesmo com a instituição de tratamento para doença renal crônica, não apresentou progresso. A uretrocistografia retrógrada e a histologia foram os exames decisivos para detectar o fibrossarcoma uretral. A ultrassonografia e a citologia por sondagem traumática não foram conclusivos, devido ao fato de a massa apresentar-se em região media de uretra e o caráter pouco esfoliativo da neoplasia.


A case of fibrosarcoma located at medium portion of the urethra of a female dog which presented pollakiuria, estranguria and hematuria at the beginning of urination was reported. The patient also presented polyuria, polydipsia, emesis and anorexia for two days. The complementary exams lead to the diagnosis of bilateral hydronephrosis, right renal hypoplasy and a mass in the urethra causing a dorsal dilatation at its medium portion. A biopsy was not performed antemortem because the general condition of the patient, which even with the institution of treatment for chronic kidney disease, showed no progress. The retrograde cystourethrography and histopathology examinations were decisive to detect urethral fibrosarcoma. Ultrasonography and cytology through traumatic probe were inconclusive, due to the mass location and its exfoliating properties.

ABSTRACT

Onze cães, sem raça definida, machos, adultos, não castrados e hígidos foram submetidos à punção aspirativa com agulha fina da próstata guiada por ultrassom para avaliação citológica e, após um período mínimo de sete dias, à videolaparoscopia para obtenção de fragmento prostático para avaliação histológica. Nos exames citológicos, dois animais apresentaram alterações celulares compatíveis com hiperplasia prostática benigna. Durante a videolaparoscopia, a colheita do fragmento prostático foi realizada de maneira rápida, não sendo observada hemorragia significativa após o procedimento. Os animais não apresentaram nenhuma complicação no período pós-operatório. Verificaram-se, ao exame histológico, morfologia e estrutura celulares e teciduais nos padrões normais do parênquima prostático em 10 animais; um único cão apresentou alterações celulares e teciduais sugestivas de hiperplasia prostática benigna.


Eleven healthy intact male mongrel dogs were submitted to prostate ultrasound fine needle aspirative puncture for cytologic exam and, after seven days or more, to videolaparoscopic fragment collection for further histologic evaluation. On cytologic exams, two animals presented changes which correlates with benign prostatic hyperplasia. During the videolaparoscopic proceedings, the prostate fragment collections were made in a quick way and no important hemorrhagic lost has been seen after the collection. The animals presented no complication after the surgeries. The histologic exams showed normal prostate parenchyma based on the cellular and tissue morphology and structure in ten dogs; only one presented cellular and tissue changes suggesting benign prostatic hyperplasia.

ABSTRACT

A decoction of the leaves of Laportea ovalifolia is widely used in Cameroon for the treatment of several illnesses, including diabetes mellitus. The antidiabetic and hypolipidaemic effects of a methanol/methylene-chloride extract of the aerial parts of L. ovalifolia have now been investigated, in normal rats and rats with diabetes induced by the intraperitoneal injection of alloxan (at 150 mg/kg bodyweight). In the diabetic rats, 2 weeks of daily, intragastric treatment with the L. ovalifolia extract not only produced a significant reduction in the fasting serum glucose concentrations but also lowered the serum concentrations of total cholesterol, triglycerides, and low-density-lipoprotein cholesterol, lowered the ratio of total cholesterol to high-density-lipoprotein (HDL) cholesterol, and increased the serum concentration of HDL cholesterol. At least in rats with alloxan-induced diabetes, the methanol/methylene-chloride extract of L. ovalifolia therefore appears to possess antidiabetic and hypolipidaemic properties.
