![]() Os CMMs foram frequentes em ambas as porções e correlacionaram-se com o IRS. A arquitetura geral do rim cefálico e exócrino foi semelhante à descrita para outras espécies de teleósteos. ![]() Todas as variáveis corporais biométricas foram correlacionadas com o IRS, principalmente o peso renal e a contagem de lesões superficiais. O conteúdo de lipofuscina e hemossiderina foi estimado visualmente nos centros de melanomacrófagos (CMMs). Fragmentos de ambos tecidos foram processados para análise e microscopia de campo claro. Análises histométricas e a densidade volumétrica estrutural foram associadas ao índice renossomático (IRS). O objetivo deste estudo foi descrever características anatômicas, histológicas e histopatológicas no rim cefálico e exócrino. Gymnotus inaequilabiatus é um peixe neotropical amplamente distribuído em áreas marginais de baías. These findings may be used in future studies to evaluate the effects of environmental stressors on the renal adaptative physiological process.įish Pathology Renal morphology Stereology Teleost The RSI is an useful biometric variable that represent some physiological and morphological characteristics of kidney in G. Of all the structures hystometrically estimated, only proximal tubular diameter and thickness, and distal tubular thickness were correlated to renosomatic index. Granulomatous structures were often observed in both portions however, they were associated only in the exocrine kidney with RSI. MMCs were prevalent in both portions and correlated with RSI in the head and exocrine kidney. The general architecture of head and exocrine kidney was similar to that described for other teleost species. All the biometric body variables were correlated with RSI, especially the kidney weight and gross lesions count. Lipofuscin and hemosiderin content were visually estimated in the melonomacrophages centers (MMCs). The kidney was processed for light microscopy. Here, histometric and structural density techniques were associated with renosomatic index (RSI). The aim of this study was to describe the main histological and histopathological traits in the head and exocrine kidney. The Gymnotus inaequilabiatus is a Neotropical fish widely distributed in marginal areas of bays.
