The influence of 2.5 g exposure on the morphology of rat vestibular epithelia.
نویسنده
چکیده
Several studies have shown that altered gravity causes changes in vestibular induced reflexes and behaviour, and in vestibular morphology. How the level of gravity affects the morphology of vestibular epithelia, however, is largely unknown. Vestibular epithelia of hypergravity (HG) exposed animals and control animals were histochemically labeled for actin and tubulin (two characteristic proteins for specific cytoskeletal structures in hair cells and supporting cells). Cellular organization, cytoskeletal structure and apical cross-sectional area were investigated.

Effects of hypergravity on the morphological properties of the vestibular sensory epithelium. I. Long-term exposure of rats after full maturation of the labyrinths.
The effect of prolonged exposure to hypergravity on the morphology of vestibular epithelia of rats was investigated. At the age of 1 month, i.e., when vestibular end organs are fully maturated, three rats were transferred to a hypergravity environment of 2.5 g inside a large radius centrifuge. After 9 months, vestibular epithelia of these animals and of three control animals were immunohistoche...
متن کاملPost Exposure Effects of Propoxur (Agricultural Pesticide) on Male Fertility in Wistar Rat
Background: Pesticide toxicity is one of the major environmental health problems for the modern societies, as some of the effects may last long time after exposure. Propoxur is one of the Carbamate pesticide largely used in agriculture in the Western region of Cameroon. Methods: In order to evaluate the post-exposure effects of propoxur, 48 male rats (12 animals per group) aged 30 d were orall...
متن کاملThe Consequence of Vitamin E Exposure on In Vitro Cadmium Toxicity in Rat Bone Marrow Mesenchymal Stem Cells
This investigation aimed to examine the protective function of vitamin E on rat bone marrow mesenchymal stem cells (MSCs) treated with cadmium chloride. Rat bone marrow MSCs were extracted using flashing-out and cultured in DMEM containing 10% FBS and 100 U/ml Pen/Strep. At the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...

In this work, the performance of organic pollutant removal, membrane fouling and sludge morphology in a submerged membrane bioreactor (MBR) treating sunflower oil refinery wastewater (SORW) containing high oleic content was studied during 52 days’ operation at short values of 18 h and 10 days for hydraulic retention time and sludge retention time, respectively. The removal efficiencies of chemi...

Introduction: In this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. Methods: Bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μM of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan bl...
