Objective To investigate the impact of motor imaginary therapy on the recovery of upper limb function in acute cerebral infarction patients with bemiplegia. Methods Fifty cerebral infarction patients with hemiplegia were randomly divided into a control group (drug therapy + early exercise therapy) and a motor imaginary therapy group (drug therapy + early exercise therapy + motor imaginary therapy) using single-blind method (n = 25 in each group). Ipsilateral upper extremity function was assessed by the Fugl-Meyer assessment (FMA) before the treatment and at day 40. The active range of motion (AROM) of the ipsilateral wrist was measured by a conimeter. Eating, washing, dressing, and putting on and off clothes were assessed by the Functional Independence Measure (FIM) scale. Results The scores of FMA, AROM and FIM were increased more significantly than those before the treatment in both groups (P <0.05). All the scores in the motor imaginary therapy group after the treatment were superior to those in the control group (P <0. 05) (FMA 28.33 ± 8.63 versus 15.93 ± 5.39;AROM 19.55 ± 8.30 versus11.97 ± 6.59; FIM 16.83 ± 5.43 versus 12.51 ± 3.36).Conclusions Conventional motor rehabilitation training + motor imaginary therapy during the acute phase may promote the motor function reco,,ery in cerebral infarction patients with hemiplegia.

In this paper we established a method of preparing chromosomes of peritoneal cells and made use of the method for observing the Y-chromosome of marrow and peritoneal cells of female mice which had been irradiated with 850 rad ~(60)Co-?, rays and then transplanted with marrow cells of male mice. The results showed that the chromosome karyotypes of the marrow cells of the female mice were of the XY type of male mice. It means that the marrow cells of the recipients were substituted by those of the donors. At the same time, the chromosome types of the peritoneal cells of the recipients were also of the XY type. It is suggested that the peritoneal cells were derived from the marrow cells.By the use of the method for assaying CFU-C and CFU-S of mouse marrow cells, CFU-C and CFU-S of peritoneal cells of mice were assayed. The result demonstrated that there were a number of CFU-C and CFU-S among the peritoneal cells.On the observation of the cell morphology of CFU-C and CFU-S, it was discovered that CFU-C differentiated mainly into mononuclear phagocytes, while CFUS had the ability to differentiate into erythrocytie series and granulocytic series, which implies that there were some multipotential stem ceils among peritoneal cells of mice.When more than 10~6 peritoneal cells per mouse were transplanted into the mice which had received 850 rad of ~(60)Co-? rays, their life span could be prolonged.It is still a question unsetteled that whether the stem cells in the peritoneal cavity differentiate diroctly into the mononuclear phagocytes or the mononuclear cells in the blood penetrate into the peritoneal cavity and then differentiate into the macrophages.
