Fenugreek seed extract alleviates hippocampal dendritic atrophy in streptozotocin induced diabetic rats

Int. j. morphol; 38 (6), 2020
SUMMARY: Herbal extracts used for treatment of diabetes has focused mostly on the hypoglycaemic and anti-oxidant property.There are no studies which focused on its effect on dendritic architecture of pyramidal neurons of hippocampus caused by diabetes. This study was taken up to explore the effect of adm...

Heat shock response in noise-induced hearing loss: effects of alanyl-glutamine dipeptide supplementation on heat shock proteins status

Abstract Introduction: The 72 kDa heat shock protein, HSP72, located intracellularly provides cochlear cytoprotective and anti-inflammatory roles in the inner ear during stressful noise challenges. The expression of intracellular HSP72 (iHSP72) can be potentiated by alanyl-glutamine dipeptide supplement...

ω-Conotoxina MVIIC e células-tronco mesenquimais promovem recuperação motora em ratos Wistar após trauma medular agudo

O objetivo deste estudo foi avaliar o efeito da ω-conotoxina MVIIC e das células-tronco mesenquimais (CTM) de forma isolada e sua associação nos ratos submetidos ao trauma medular agudo (TMA). Trinta Rattus novergicus, linhagem Wistar, três meses de idade, foram distribuídos igualmente em cinco gru...

Effects of rocuronium, sugammadex and rocuronium-sugammadex complex on coagulation in rats

Rev. bras. anestesiol; 70 (6), 2020
Abstract Background and objectives: Sugammadex is an alternative pharmacological drug capable of reversing neuromuscular blockades without the limitations that are presented by anticholinesterase drugs. Coagulation disorders that are related to treatment with sugammadex were reported. The exact mechanis...

Ototoxicity of cypermethrin in Wistar rats

Abstract Introduction: This study presents the effect of cypermethrin on the cochlear function in Wistar rats post-subchronic inhalation exposure. Worldwide several pesticides are described as causing health disorders. Cypermethrin is currently one of the most commonly used, however, little is known abo...

Induction of brain injury and depression in rats by chronic unpredictable stress associated with the augmentation of nitrosative stress and apoptosis

Int. j. morphol; 38 (5), 2020
SUMMARY: Repeated stress is a risk factor for memory impairment and neurological abnormalities in both humans and animals. We sought to investigate the extent of (i) brain tissue injury; (ii) nitrosative and oxidative stress in brain tissue homogenates; (iii) apoptotic and survival biomarkers in brain ti...

Effects of ultrasound and stretching on skeletal muscle contusion in rats: immunohistochemistry analysis

Int. j. morphol; 38 (5), 2020
SUMMARY: The aim of this study was to evaluate the effects of stretching and therapeutic ultrasound (TUS) on desmin and laminin contents of rat muscle after contusion. Male Wistar rats (n = 35, 8-9 weeks of age, 271 ± 14g body weight) were divided into five groups: Control group (CG) (n= 03); Injured gr...
