ABSTRACT
@#Objective To study the effect of foot motor imagery on lower extremity motor function in hemiplegics after stroke. Methods 72 hemiplegics were randomly divided into two groups: the experiment group and the control group. Normal rehabilitation was performed in the both groups and motor imagery was added in the experiment group. They were assessed with lower extremity Fugl-Meyer Assessment (FMA) and gait analysis. Results The scores of FMA in knee, ankle and lower extremity, gait frequency and speed improved in experiment group more than in controls（P<0.05）. Conclusion Foot motor imagery can improve lower extremity motor function.
ABSTRACT
Acute myocardial ischemia and reperfusion led to arrhythmias and increase of glutamic oxalacetic transaminase (GOT),lactate dehydrogenase (LDH),non-csterified fatty acid (FFA) and malondialdehyde (MDA) content, and decrease of superoxide dismutase (SOD) activity in rats. 3, 6-di-methylamino-dibenzopyri-odonium edetate (IHC-72) 5 mg?kg-1 iv significantly reduced the incidence of ventricular tachy-cardia (VT) and ventricular fibrillation(VF) ,shortened the duration of arrhythmias induced by reperfusion, decreased the release of GOT, LDH and FFA, obviously reduced the MDA content,and effectively protected SOD activity in ischemia-reperfused rat hearts. Our experimental results suggested that IHC-72 had protective effects on ischemia-reperfusion injury rat hearts in vivo. The mechanism of the protection might be associated with the inhibition of cellular lipid peroxidation.
ABSTRACT
Studies of the scalps from 42 patients with alopecia areala are given,using direct immunofluorescence ( DIP).Langerhans cells (LC)and T-lyrn hocytc subsets are observed.There is no significant difference between the number of OKT6 cells and Ia+ cells in the epidermis of all groups and the control.LC is seen in hair-bulb in many patients and most frequently in active stage.The main change of LC in hair follicle is increasing of T6+Ia- cells,not significant of T6+Ia+ cells.Most of the infiltrates around the hair follicles are T( OKT3+) cells.T4+cells number and T4/T8 ratio in active arc larger than in resting and recovering stages.DIF shows 88% of the patients having deposits of C3,IgG,and IgM.This suggests that alopecia areata may be the disorder of immnue associated with cellular and humoral immunity.
