Vitamin C administration attenuated artemether induced hepatic injury in rats

Int. j. morphol; 38 (1), 2020
This research was designed to investigate the potential protective effect of vitamin C supplementation against hepatocyte ultrastructural alterations induced by artemether (antimalarial drug) administration. Twenty-four adult male albino rats were used in this study and were divided into four groups (n=6...

Vitamin E protects against hepatocyte ultrastructural damage induced by high fat diet in a rat model of pre-diabetes

Int. j. morphol; 36 (4), 2018
SUMMARY: We sought to investigate the potential protective effect of Vitamin E supplementation against hepatocyte ultrastructural alterations induced by high fat diet (HFD) in a rat model of pre-diabetes. Therefore, rats were either fed with HFD (model group) or a standard laboratory chow (control group)...

Effect of cigarette smoking on the structure of hepatocytes: TEM study

Int. j. morphol; 34 (4), 2016
The liver is one of the major organs that is indirectly affected by cigarette smoke. The aim of this project is to define the histologic and ultrastructural changes in normal liver cells after exposing animals to cigarette smoke. Thirty albino rats were exposed to cigarette smoke for 90 days, followed by...

Microscopía electrónica de nucleos hepáticos estimulados con dosis crecientes de laser infrarrojo

Int. j. morphol; 33 (1), 2015
Un total de 20 ratas hembras de 4 meses de vida con peso aproximado de 250 gramos fueron divididas en 4 grupos de animales rotulados como A, B, C y D. El grupo A corresponde al control y los demás grupos recibieron respectivamente estimulaciones con laser infrarrojo con dosis crecientes de 4, 8 y 16 Jou...

Metformin induces ultrastructural alterations in hepatocytes of spontaneously hypertensive rats

Int. j. morphol; 32 (3), 2014
Metformin, an oral biguanide approved for the treatment of type II diabetes is widely prescribed for other clinical conditions. Currently, metformin is being investigated as potential anti-tumor agent. However, there have been recent concerns about hepatotoxicity associated with the use of metformin. Thi...

El retículo endoplasmático liso en hepatocitos estimulados con distintas dosis de láser infrarrojo

Int. j. morphol; 32 (3), 2014
Veinticuatro ratas hembras Sprague Dawley de 4 meses de vida con peso aproximado de 250 g, fueron divididas en cuatro grupos (A, B, C y D), donde el grupo A (control) no recibió estimulación infrarroja, B se irradió con láser infrarrojo 4 J/cm², C con dosis de 8 J/cm² y D con 16 J/cm². La estimula...

Micro-ultrastructure features of liver in Chinese Taihe black-bone silky fowl (Gallus gallus domesticus Brisson)

Int. j. morphol; 32 (3), 2014
In this work, the morphological features of liver in Chinese Taihe black-bone silky Fowl (BSF) were analyzed by light microscope and transmission electron microscopy. The results showed that two kinds of hepatocytes were present in Taihe BSF liver, i.e., the dark and the light hepatocyte. The dark hepato...

Análisis morfométrico de hepatoesteatosis microvesicular alcohólica de ratas

Int. j. morphol; 32 (2), 2014
Un total de 24 ratas hembras de 4 meses de vida con peso aproximado de 250 gramos fueron divididas en dos grupos de animales rotulados como A y B. El grupo A se mantuvo con pellet y agua ad libitum sirviendo como controles mientras que el grupo B conservaba el pellet y recibía una solución de alcohol 4...

Estudio Morfométrico del Efecto de Láser Infrarrojo 16 J/cm2 sobre Hepatocitos de Rata

Int. j. morphol; 29 (2), 2011
Hígados de ratas Sprague Dawley fueron irradiados durante 15 días con dosis diarias de 8 y 16 J/cm2 proveniente del láser AsGa equivalente a 904 nm. De estos animales previamente anestesiados, fueron quirúrgicamente obtenidas muestras de hígado y posteriormente procesadas para microscopía electrón...
