background and objective: evaluation of degenerative changes of motoneurons and their related synapses can be useful in understanding the mechanisms of neurodegenerative diseases and their potential treatment. the present electron microscopic and immunohistochemical study investigates the axotomy-induced changes of adult spinal motoneurons up to 3 months following sciatic nerve transection. mat...

in this study organotypic adult spinal cord slices were used to investigate whether caspases could participate in the apoptosis of motor neurons. the thoracic region of spinal cord was sliced using a tissue chopper and cultured in a medium for 6h. morphological and biochemical features of apoptosis were assessed by fluorescent staining and terminal deoxynucleotidyl nick end labeling (tunel) met...

background and objective: as apoptotic cell death is extremely involved in physiological development and many pathological situations such as cancer and neurodegenerative diseases, the understanding of its molecular machinery can be useful in designing new therapeutic strategies. the present study investigated the temporal expression of the proapoptotic protein bax in adult spinal motoneurons. ...

it has been shown that the immunophilin ligands have the special advantage in spinal cord repair. in this study, the effects of cyclosporine a (csa) on functional recovery and histological outcome were evaluated following spinal cord injury in rats. after spinal cord hemisection in thirty six adult female sprague-dawley rats (200- 250 g), treatment groups received csa (2.5 mg/kg i.p.) at 15min ...

background and objective: parkinson’s disease (pd) is a common neurological disorder due to degeneration of dopaminergic neurons within pars compacta of substantia nigra (snc). with regard to protective effect of malva sylvestris (ms), this study was conducted to evaluate the effect of aquaeous extract of this plant in an experimental model of pd induced by 6-hydroxydopamine (6-ohda). materials...

spasticity is one of the common complications in upper motor neuron lesions and without appropriate treatment it causes disturbances in movement pattern. assessments of patients are effective in patient`s management. modified ashworth scale (mas) is one of the criteria in qualitative assessment of spasticity, and there are lots of controversies about its validity. the purpose of this study is t...

objective: the apoptosis of motor neurons is a critical phenomenon in spinal cord injuries. adult spinal cord slices were used to investigate whether voltage sensitive calcium channels and na+/ca2+ exchangers play a role in the apoptosis of motor neurons. materials and methods: in this experimental research, the thoracic region of the adult mouse spinal cord was sliced using a tissue chopper an...

the aim of the present study was to investigate the effect of endurance training on syd gene expression in motor neurons of rats with diabetic neuropathy. 12 wistar male rats were randomly assigned to 3 groups (each group 4 subjects): diabetic trained (dt), diabetic untrained (dc) and healthy control (hc). two weeks after stz injection to induce diabetes, diabetic neuropathy was demonstrated by...

background: the aim of this study was to investigate the preventive effect of the polyamine component n, n, n´, n´-tetrakis(2-aminoethyl)2,2-dimethylpropane-1,3-diamine (tdmtn) on apoptotic motor neurons in adult mouse spinal cord slices. materials and methods: thoracic region of adult mouse spinal cords was sliced by a tissue chopper into 400 μm slices and cultured in medium in the presence or...

Introduction: Since Curcuma longa extract and curcumin have been shown to be potent antioxidant agents, they were used in cultured adult mouse spinal cord slices to investigate whether they can inhibit apoptosis in motor neurons. Methods: Slices from the thoracic region of adult mice spinal cord were divided into four groups: 1. Freshlyprepared slices (time 0) 2. Control 3. Slices treated by cu...
