ALB and nephrotic syndrome: One of the findings in this study was that a significant increase in serum albumin level before improvement in proteinuria was observed, which suggests that the mechanism underlying JPQSF's initial effect on plasma albumin level might be independent of the reduced urinary protein excretion. Astragalus and Angelica, two components of JPQSF, have been shown to improve protein metabolic disorder in patients with nephrotic syndrome by promoting net protein synthesis.
