RESUMEN
; 3. therapy with A&A (A&A); 4. Astragali alone (A); 5. Astragali polysac-charide Ⅰ (APⅠ); 6. AP Ⅱ ; 7. Astragali glucoside (AG), Results The level of serum albumin,albumin mRNA and albumin gene transcription were measured by biochemistry, Northern blot hybridization, nuclear run-on assay and quantity in laser density screening. The level of serum albumin in N was significantly lower than C. The serum albumin concentration in each therapy group was higher than N group. The transcription of the albumin gene was higher in N than in C and highest in A&A. The alterations of northern blot hybridization were same as the transcription results. But both the level of albumin mRNA and the transcription of albumin gene in A, AP I , AP I and AG were no change compared with N. Conclusion A&A increases albumin mRNA expression at least in part by improving the rate of gene transcription, which participate the protection of the decrease of serum albumin in NS. But the effect of A, AP 1 , AP I and AG may mediated by other unknown mechanisms.
