Renal histological alterations induced by acute exposure of titanium dioxide nanoparticles

Int. j. morphol; 37 (3), 2019
SUMMARY: Titanium dioxide nanoparticles (TiO2 NPs) are widely used in many commercial products, nanomedicine, agriculture, personal care products, different industries and pharmaceutical preparations with potential risk in human health and the environment. The current work was conducted to investigate th...

Investigation of the effect of GnRH (deslorelin) on the histochemical structure of salivary glands in rats

Int. j. morphol; 37 (3), 2019
This study was planned to determine the histochemical alterations of the submandibular gland by implantation of long-term GnRH (deslorelin 4.7 mg). Eighteen Wistar albino rats were used in the study. Alcian blue (AB; pH: 2.5), periodic acid-Schiff (PAS) staining was performed to determine the microscopic...

Impairment induction by axotomy in motor functional and histological anterior horn of spinal cord structure

Int. j. morphol; 37 (3), 2019
We have surveyed the motor changes in rats subjected to sciatic nerve axotomy. The rats were divided into two groups, each one consisting of ten animals, which underwent the following intervention: The first group (control): healthy rats without any injuries and experimental group: rats with injured scia...

Eficácia da estimulação elétrica com corrente russa após neurorrafia término-lateral do nervo fibular comum: análise eletroneuromiográfica e de força muscular

RESUMO Lesões de nervos periféricos levam a perda funcional elevada no tecido muscular. Assim, muitas pesquisas têm investigado técnicas cirúrgicas, como neurorrafias, e recursos terapêuticos, como eletroestimulação, para melhorar a funcionalidade de um músculo reinervado após lesão periféric...

Macrophage migration inhibitory factor antagonist (p425) ameliorates kidney histopathological and functional changes in diabetic rats

J. bras. nefrol; 41 (3), 2019
Abstract Introduction: It is hypothesized that increased macrophage migration inhibitory factor (MIF) expression may contribute to diabetic nephropathy (DN) pathogenesis. The aim of the present study was to investigate the renal effects of MIF inhibition in a diabetic experimental model. Methods: Eight...

Acute Physical Stress Preconditions the Heart Against Ischemia/Reperfusion Injury Through Activation of Sympathetic Nervous System

Arq. bras. cardiol; 113 (3), 2019
Abstract Background: Stress is defined as a complicated state that related to homeostasis disturbances, over-activity of the sympathetic nervous system and hypothalamus-pituitary-adrenal axis responses. Cardiac preconditioning reduces myocardial damages. Objective: This study was designed to assess the...

Improvement of fertility parameters with tribulus terrestris and anacyclus pyrethrum treatment in male rats

Int. braz. j. urol; 45 (5), 2019
ABSTRACT Objective Anacyclus Pyrethrum (AP) and Tribulus Terrestris (TT) have been reported as male infertility treatment in several studies; however, in Iranian traditional medicine these two plants are prescribed simultaneously. In this study, we aimed to determine the effects of AP and TT extracts b...

Memory impairments and increased GFAP expression in hippocampal astrocytes following hypercaloric diet in rats

Arq. neuropsiquiatr; 77 (9), 2019
ABSTRACT Objective: Hypothalamic inflammation and glial fibrillary acidic protein (GFAP) overexpression in astrocytes are well described in obese animals, as are some cognitive and memory deficits. As the hippocampus plays important roles in the consolidation of information, this investigation aimed to ...

Preventive effects of Topiramate on methylphenidate induced behavioral disorders

Neuronal cell damage is often caused by prolonged misuse of Methylphenidate (MPH). Topiramate (TPM) carries neuroprotective properties but its assumed mechanism remains unclear. The present study evaluates in vivo role of various doses of TPM and its mechanism against MPH-induced motor activity and relat...

Antihypoxic and anti-ischemic properties of the North Caucasus flora plant extracts

Nowdays it is established that ischemic brain damage like ischemic stroke is one of the leading cause of death and disability in the population that assumes relevance development of anti-ischemic drugs. The work studied the anti-hypoxic and anti-ischemic effect of 7 plant extracts. Antihypoxic activity w...
