The assessment is made on 139 acute stroke patients treated at the Central Military Hospital 108 from December 2000 to September 2001. Out of these 139 patients (64 with intracerebral haemorrhage, 75 with cerebral infarction), 8 patients had gastroitestinal haemorrhage. The patient's ages ranged from 20 years old to 91 years old. Gastrointestinal haemorrhage occurred in stroke patients, both intracerebral haemorrhage (4 out of 8 cases) and cerebral infarction (4 out of 8 cases). Gastrointestinal haemorrhage tends to occur more on stroke patients with higher age. Gastrointestinal haemorrhage often occurs during the first ten days after the stroke. The anemia caused by gastrointestinal haemorrhage in stroke patients is not serious but it often causes serious conscious disturbances. Gastrointestinal haemorrhage increases the risk of aspiration pneumonia resulting in high death rate.

Background: Bone marrow stem cells with their plasticity can be used to replace and repair the other damaged organs and tissues, so they can also be used to obtain bone healing of nonunions. Objective: to evaluate the results of percutaneous autologous bone marrow grafting to treat the tibia diaphyseal nonunions. Subjects and methods: 12 patients with noninfected nonunion of the tibia were diagnosed and treated in Viet Duc Hospital. About 250mL of marrow was aspirated, then separated and concentrated by density gradient centrifugation. The final mononuclear cell mass containing stem cells and progenitors was washed in 30ml of 0.9% NaCL and then injected into the damaged sites. Patients were evaluated by clinical and X-rays examinations with at least 6 months follow-up. Results: None of the patients had post - op complications. Bone union was obtained in eleven of the twelve patients (91,7%) at an average of 15,3 weeks (range, 9 - 30 weeks), the bone marrow grafts used for these patients who had bone union contained a mean of 5,65 \xb1 3,74 x 106 (0,95 - 11,73 x 106) CD34(+) stem cells in total. Conclusions: Percutaneous autologous bone - marrow grafting is a minimally invasive alternative and a simple, effective, safe method for the treatment of the tibia diaphyseal nonunions with the comparative bone healing rate. \r\n', u'\r\n', u'
