introduction: in the present research, the effect of morphine consumption during pregnancy on the development of the embryo’s spinal cord was studied in wistar rat. methods: female wistar rats (wt: 250-300 g) were mated with males. the test group received morphine (0.01 mg/ml) in their drinking water. pregnant rats were later killed with chloroform on the 12th, 13th and 14th days of pregnancy, ...

background: the purpose of this study is to investigate the relationship between the cognitive impairment and naa/cr and cho/cr ratios in the proton magnetic resonance spectroscopy (1hmrs), and to assess the importance of 1hmrs in the early diagnosis of cognitive impairment in patients with ischemic white matter lesions (wmls). materials and methods: a total of 45 patients (23males and 22 femal...

white matter lesions (wmls) are commonly observed in strokepatients with small vessel disease (svd) and are thought toresult from a progressive, irreversible disease process followingarteriolosclerosis. in this study, we report a case of partialdisappearance of wmls 1 year after a lacunar stroke in a69-year-old man with evidence of svd. we also discuss possiblemechanisms associated with this ob...

in this study, the vertical, transverse and oblique diameters of the spinal cord segments (c1, c6, c12, c18, t1, t4, l1, l4, l6 and l8) and the ratio of gray matter to white matter in chick (l month) and adult (18 months) male ostriches, each group consisted of 3 animals, were measured with standard micrometric method using 6 μm thick sections by light microscope. with advancement of age, the r...

background: volume estimation of brain is important for many neurological applications. it is necessary in measuring brain growth and changes in brain in normal/abnormal patients. thus, accurate brain volume measurement is very important. magnetic resonance imaging (mri) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. st...

background previous studies have proven the development of white matter hyperintensities (wmh) in methamphetamine and opioid users. opiates and methamphetamines (ma) are the most common addictive agents in iran. the adverse effects of drugs on the cns is of concern to specialists and researchers, and given that the neurotoxicity associated with methamphetamine is greater than opioids, it is hyp...

change in transmitting time of impulses along axons is traditionally attributed to two parameters: the myelin formation and the diameter of neurite, both rising during the postnatal development. in the previous study, we showed that conduction velocity of the fibers projecting from the thalamus to the layer iv of the somatosensory (barrel) cortex increases as a function of age. however, the con...
