Rats in the ischemia-reperfusion group were assigned into 8 subgroups according to 8 time phases,respectively at reperfusion for 30,60 minutes,2,4,6,9,12 and 24 hours following spinal ischemia,with 7 rats at each time phase.
Righting reflex disappeared immediately after injecting with ketamine in the mice of the formalin+ketamine group. The reaction number of pain behavior at the first time phase (0-5 minutes after injection) and second time phase (20-60 minutes after injection) after inducing inflammation was less obviously than that in the formalin group (6.0±2.5),(113.0±9.5) times;
The selfscanning property of CCD is used to translate the moire fringes distributing in space into the dynamic signal changing with time. The time phase of the photoelectric signal is corresponding to the space location of the moire fringe.
Results Changes in c fos gene expression induced by alcohol and acetaldehyde was time and dose dependent After 1 hr exposure,alcohol and acetaldehyde affected c fos gene expression in two kinds of neuralglia C fos positive expression reached peak value after 2 hr,but recovered after 72 hr and showed special time phase expression.
Methods SD rat models with modified Allen's assay were adopted for acute spinal cord injury,and spinal cord injury tissue's degeneration,necrosis,neutrophil infiltrative conditions and positive CD9,CD59 reactants' expression sites and time phase were observed in every group at 12 h,1,3,5 and 7 d after injury.
METHODS: SD rat acute spinal cord injury models were established by Allen's assay. The expression sites and time phase of C9 and CD59 positive reactants were observed in methylprednisolone group and normal saline group at 12 h ,1,3,5 and 7 d after injury and the differences between the two groups were differentiated.
MAIN OUTCOME MEASURES:To observe the degeneration of the injured tissue of spinal cord,necrosis and neutrophil infiltration condition and site and time phase of the expression of C9 and CD59 positive reactants in every group at different time points after injury.
Methods SD rat models of acute spinal cord injury were establised by modified Allen's method. The positve expression sites and time phase of C9 and Clusterin were observed in injuried tissue at 12 h,1,3,7 and 14 d after injury in sCR1 group and normal saline group. Motor function of rat lower extremities was evaluated viathe tiltboard experiment and the differences between the two groups were compared.
MAIN OUTCOME MEASURES:To observe degeneration,necrosis of the injured spinal cord tissue,neutrophil infiltration and the expression sites and time phase of C9 and CD59 positive reactants of all groups at different time points after injury.
This paper studies a new real-time phase-shifting method for the analysis of isochromatic and isoclinic parameters in photoelasticity.
To avoid the side effect of severe noise multiplication,an alternative receiver structure is developed, incorporating adiscrete-time phase tracker to allow the reduction of the constellationsize prior to the correlation operation.
In the first method, access privilege to a particular section of memory is exclusively granted to each vector stream in its own time phase.
