abstract background: previous studies have shown that morphine consumption during pregnancy may delay embryo development or cause abnormal nervous system function. objective: the present study focused on the effect of maternal morphine consumption on development of placenta and blood corticosteron concentration in addictive pregnant mothers. materials and methods: 24 female rats, 170-200g weigh...

The mode of development of Venezuelan equine encephalomyelitis virus and the activity of acid phosphatase in the central nervous system of newborn mice were investigated. Precursor particles appeared to be formed in masses of viroplasm, migrating to the membrane of the Golgi cisterns and vacuoles or to the plasma membrane and being transformed into mature viral particles by budding. Mature vira...

background : collection and storage of roof rain water have been practiced for long time ago in iran and many other countries. water of cisterns is usually used as potable water. in golestan province many of rural torkman residents reservoir the most part of their potable water from roof rain in cisterns. in this province there are over 2600 cisterns. methods : to study the water quality, micro...

Computed tomography (CT) of the head has become the diagnostic tool of choice, particularly for moderate and severe traumatic brain injury (TBI). Various CT characteristics are associated with outcome, and may therefore be used as outcome predictors. One of the most prominent predictors appears to be the status of the basal cisterns. This study describes the prognostic value of the appearance o...

BACKGROUND AND PURPOSE Abnormal ECG changes are frequently observed in patients with subarachnoid hemorrhage (SAH). Recently, evidence has been obtained that right insular cortex mediates sympathetic cardiovascular effects. We therefore assessed the laterality and location of SAH dominance in inducing cardiovascular changes as measured by ECG, blood pressure, and heart rate. METHODS After exc...

By immunogold electron microscopy we have shown that in mouse cerebellar Purkinje cells fixed by perfusion with formaldehyde-glutaraldehyde solution, the InsP3 receptor are numerously detected on the stacks of flattened cisterns (OTSU et al, (1990) Cell Struct. Funct., 15: 163-173). In the present experiment we investigated distribution, structure and properties of the stacks by conventional el...

The initial CT scans of 76 patients with aneurysmal subarachnoid haemorrhage were reviewed, and the amount of blood visible in the basal CSF cisterns was quantified. The outcome of surgery was found to correlate significantly with the quantity of blood seen on the scan, as did the pre-operative grade of the patient, a history of pre-existing hypertension, and the presence of angiographic vasosp...

According to several studies, the amount of subarachnoid blood on the initial computed tomogram of patients with aneurysmal subarachnoid hemorrhage has predictive value with respect to infarction and outcome. Of several methods for assessing the amount of subarachnoid blood, none has been subjected to a study of interobserver agreement. We describe our own method, applied in previous studies, i...
