RESUMO

To detect the soluble Fas (sFas) receptor level in sera from patients with myelodysplastic syndrome (MDS) and acute leukemia (AL), and investigate its clinical significance, the levels of sFas receptor in sera from 18 patients with MDS and 42 patients with AL were detected by using ELISA methods. The results suggested that the sFas receptor levels in sera from patients with MDS-RA were significantly lower than that from normal control (2.89?1.72 ng/ml vs 6.29?1.07 ng/ml, P

RESUMO

AIM and METHODS: To detect the changes of amyloid protein (?-AP) and polypeptide growth factor levels and study their role in the possible pathogenesis of Alzheimers disease (AD) and vascular dementia (VD). We detected serum ?-AP, transforming growth factor- ?(TGF-?) and insulin-like growth factor (IGF-Ⅱ) levels by radio immunoassay in 8 patients with AD,15 patients with VD and 63 patients with ischemic cerebrovascular disease(ICVD) and 38 cases healthy volunteers. RESULTS: In AD and VD groups, serum ?-AP, TGF-? and IGF-Ⅱ were significantly higher than that in ICVD and control group; Serum ?- AP,TGF-? and IGF-Ⅱ contents in ICVD group were obviously higher than that in normal control, the highest increase occurred in sequel of cerebral infarction(SCI) and vertebrobasislar ischemia(VBI) groups. There are positive correlation among ?- AP, TGF-? and IGF-Ⅱ in AD and VD groups.CONCLUSION: ①?- AP is a risk factor in the pathogenesis of AD and VD. ② TGF- ? and IGF-Ⅱ play roles in the neurotoxin effect that lead to dementia. ③ ?-AP plays a important role in formation of senile plaque.
