Evaluation of the ethanol intake on the Calomys callosus seminal vesicle structure

Micron, 2008
The effects of chronic alcohol ingestion on the structure of the glandular epithelium of the seminal vesicle of the rodent Calomys callosus were analyzed in 24 adult animals aged 3 months divided into three experimental groups. The control group received a solid diet and tap water, the alcoholic group received the same solid diet and ethanol P.A ...

Chronic ethanol ingestion on the uterine horn of Calomys callosus

2023
The present work was carried out to evaluate the possible effects of chronic alcohol intake on the histology and ultrastructure of the endometrial lining epithelium of the uterine horn of Calomys callosus. 20 adult female rodents, Calomys callosus, three months old, were used. These animals were divided equally into 2 experimental groups called control

Trophoblastic invasion of the uterine epithelium in Calomys callosus (Rodentia, cricetidae)

Journal of Morphology, 1994
AbstractImplantation sites in the uterus of the cricetid rodent Calomys callosus were examined by light and electron microscopy at several points during day 4 of pregnancy to determine the changes occurring in the trophoblast and epithelial cells during the early blastocyst‐endometrial relationship, particularly the epithelial removal phase. By morning,

Structural evaluation of the effects of chronic ethanol ingestion on the testis of Calomys callosus

Tissue and Cell, 2009
Chronic exposure to ethanol may results in pathophysiologic changes in cellular function. The present work was designed to investigate the morphology of testis submitted to experimental ethanol ingestion. Experimental animals were divided into two groups.

Influence sexual dimorphism on the persistence of blood parasites in infected Calomys callosus

Research in Veterinary Science, 2008
Gender has long been known to be a contributory factor in the incidence and progression of disorders associated with immune system disregulation. The aims of this experiment were to verify the influences of sexual dimorphism on the persistence of blood parasites out of the acute phase of infection.

Cytological aspects of vascular invasion by the trophoblast of Calomys callosus in hepatic tissues

Journal of Morphology, 1995
AbstractEctoplacental cones isolated from embryos on the seventh day of pregnancy wer transplanted beneath the hepatic capsule of recipeint adult animals to document the morphological patterns of vascular invasion by the trophoblast in the absence of the maternal environment and the influence of its peculiar vasculature.

Trypanosoma cruzi: Effects of social stress in Calomys callosus a natural reservoir of infection

Experimental Parasitology, 2008
Social environment can represent a major source of stress affecting cortisol and/or corticosterone levels, thereby altering the immune response. We have investigated the effects of social isolation on the development of Trypanosoma cruzi infection in female Calomys callosus, a natural reservoir of this protozoan parasite. Animals were divided in groups

Fine structure of the 7 postnatal days Calomys callosus palatine salivary glands

Annals of Anatomy - Anatomischer Anzeiger, 2002
The aim of this study has been to determine the ultrastructural characteristics of the minor palatine salivary glands on the seventh day of development and to demonstrate wether their secretion is mucous, serous or seromucous by light, transmission and scanning electron microscopy.

Mast cells in the eyes of Calomys callosus (Rodentia: Cricetidae) infected by Toxoplasma gondii

Parasitology Research, 2002
The mast cell is a powerful effector cell for the innate immune system, acting through the secretion of several distinct mediators. Few studies have demonstrated the relationship between mast cells and toxoplasmosis. In this study, mast cells were investigated in two experimental Toxoplasma infections using Calomys callosus (Rodentia: Cricetidae) as ...
