Características Estereológicas del Hígado de Rata (Rattus norvergicus) sometidas a Menopausia Inducida por Ovariectomía

Abstract: INTRODUCCIÓNLa menopausia, es el cese permanente de la menstruación después de la pérdida de la función ovárica (Santoro, 2002). Los cambios hormonales importantes que se producen, corresponden a una disminución de estradiol circulante con aumento concomitante de las hormonas folículo estimulante y luteinizante (Lip et al., 1997).Estudios experimentales sugieren que el estrógeno es un poderoso antioxidante que participa en el metabolismo de los ácidos grasos. Por lo tanto, cuando sus niveles se encuentran dism… Show more

“…For the liver, the hepatocytes of the three zones of the hepatic accia of Rappaport were studied: periportal, intermediate and perivenous. The following histological characteristics of the liver tissue were detailed: hepatocyte (relation nucleus cytoplasm, chromatin and presence or absence of intracytoplasmic inclusions), periportal spaces and characteristics of the triad [37,38]. Finally it was evaluated in all cases presence or not of ballonizing degeneration and lipid micro-or macro-vesicles, dilatation of the centrilobular veins (qualitative observation), inflammatory infiltrate in the portal cells and increased connective tissue in the hepatic parenchyma (Masson's trichromic stain).…”

“…Se estudiaron los hepatocitos de las tres zonas del acino hepático de Rappaport: periportal, intermedia y perivenosa. Se valoraron las siguientes características histológicas del tejido hepático: hepatocito (relación núcleo citoplasma, cromatina y presencia o no de inclusiones intracitoplasmáticas), espacios periportal y características de la tríada 26,27 . Posteriormente se evaluó en todos los preparados si presentaban o no:…”
