RESUMEN
Objective To study the expression of transforming growth factor beta1(TGF-β1)and its type I receptors activin-like kinase 1(ALK1)in the human brain glioma and estimate the significance in the pathogenisis and development of human glioma . Methods The mRNA and protein expressions of TGF-β1 and ALK1 were detected with semiquantitative RT-PCR ,Western blot and Immunohistochemistry in 3 normal brain tissues and 32 patiens with human glioma .Results ALK1 and TGF-β1 mRNA and protein sometimes had co-expression in human gliomas tissues .Compared with those normal brain tissues ,the expression of TGF-β1 and ALK1 mRNA and protein in high grade gliomas were significantly increased (P<0 .05) ,the overexpression of ALK1 in human gliomas was demonstrated significant positive correlation with the pathological grades of gliomas (r=0 .297 ,P<0 .05) .Conclusion The overexpression of ALK1 may play important role in the development of human brain glioma .
RESUMEN
AIM:To study the effects of water extraction of Choerospondias axillaris on inhibiting renal calculus. METHODS:The mice were fed 1% ethylene alcohol and 1?(OH)VitD3 to cause renal calculus. The concentrations of calcium and oxalate acid in urine and kidney were determined in mice to evaluate the effects of Choerospondias axillaris. RESULTS:The urinary oxalate of model group (1% ethylene glycol and 1?(OH) VitD3) increased significantly(P
