Chronic exposure to dichloroacetamide induces biochemical and histopathological changes in the gills of zebrafish

Environmental Toxicology, 2019
To evaluate the impact of DCAcAm on zebrafish gill, we measure the responses of antioxidant enzyme (superoxide dismutase, SOD), lipid peroxidation (malondialdehyde, MDA), ATPase (Na+/K+‐ATPase and Ca2+/Mg2+‐ATP) and histopathological changes of gill in ...

Early Histopathologic Changes in Grover Disease

The American Journal of Dermatopathology, 2010
Grover disease is a clinicopathologic entity characterized by acantholysis. The histologic changes typically occupy circumscribed foci, therefore early stages could go unnoticed and be misdiagnosed.To report on early histopathologic changes in Grover disease.We analyzed 22 cases of Grover disease histologically diagnosed at Wake Forest University ...

The histopathological changes of keratoconus

Acta Ophthalmologica, 1993
Abstract Seven keratoconus corneas and two normal corneas were examined in a light microscope. The histopathological changes are described with emphasis on breaklines in Bowman's layer. They seem to be a late and a secondary phenomenon. The severity of the findings are compared to the loss of visual acuity.

Protective effects of stigmasterol against ketamine-induced psychotic symptoms: Possible behavioral, biochemical and histopathological changes in mice

Pharmacological Reports, 2018
Background Stigmasterol, a naturally occurring phytoestrogen has been reported to possess many pharmacological activities. The aim of the present study was to screen the effect of stigmasterol against ketamine-induced mice model of psychosis. Methods The

Histopathologic Changes in the Allografted Canine Pancreas

Archives of Surgery, 1973
The histopathologic changes occurring in 23 allografted canine pancreases were studied. No immunologic suppression was utilized. Early hemorrhagic necrosis occurred as a consequence of major venous thrombosis of the graft. In the absence of this complication, progressive pathologic changes consisting of edema, vascular dilatation, mononuclear cell ...

Histopathological changes following removal of the perineurium

Journal of Neurosurgery, 1980
✓ Using microsurgical techniques, the perineurial sheath was stripped off the sciatic nerves of rats over a 0.5 cm length at a point where the nerve consists of a single fascicle. The nerves were excised 0 to 84 days after the injury, and were examined in semi-thin transverse section.

Histopathological changes in the temporal bone in kwashiorkor

Clinical Otolaryngology & Allied Sciences, 1980
The histopathological changes in human temporal bones are described for 2 cases of kwashiorkor--a protein/calorie malnutrition (PCM) state. There is photographic evidence of severe damge to the middle and inner ears and to the vestibulocochlear nerve.

Histopathological Observations on the Cochlear Changes in Otosclerosis

Annals of Otology, Rhinology & Laryngology, 1977
Alterations in the dimensions of the basilar membrane and spiral ligament have been implicated in the pathogenesis of sensorineural hearing loss in otosclerosis. The histopathological findings in nineteen temporal bones with otosclerotic involvement of the cochlear endosteum are reviewed.

Biochemical and histopathological changes in nephrectomized mice

Metabolism, 1998
Renal failure is characterized by the retention of nitrogenous metabolites such as urea, creatinine (CTN) and other guanidino compounds (GCs), uric acid, and hippuric acid, which could be related to the clinical syndrome associated with renal insufficiency. A model of renal failure has been developed in male C57BL x Swiss-Webster mice using nephrectomy
