Seoul, Korea. Effect of Siryungtang, Steroid, Interferon-γand Cyclosporin-A on Mitogen Interleukin4-Activity in Minimal Change Nephrotic Syndrome. Proceedings of International Symposium on East-West Medicine, Seoul. 183-186, 1999. -We have reported that patients with childhood minimal change nephrotic syndrome (MCNS) express higher levels of IL-4 mRNA expression by mitogen activated T cells using Northern blot(Cho,et al, JASN 1:518,2:590). Siryungtang(SA-1) is an oriental medicine shich has long been used in chronic renal diseases. In order to evaluate the efficacy of SA-1 on IL-4 sctivity from the monouclear cells isolated from the MCNS patients(n=5) and controls(n=5). Cells were adjusted to 2×107cells/ml with 10% FCS-RPMI and added test drugs such as SA-1, steroid(hydrocortisone, HC), CsA, IL-4& combination of SA-1＋HC,SA-1＋CsA&SA-1＋IFN-γand mitogens(PHA-P:20㎕/ml, Con-A:20㎕/ml & PMA:50ng/ml) were added. Cells were cultured at 37℃,5% CO2 incubator for 24,48 & 72hrs. Results were as follows.
표
Mean ³[H]thymidine incorporation(cpm) was higher in controls(44,920±7,482cpm)that in patients with MCNS(30,495±2.135). However ³[H]thymidine incorporation was reduced by adding SA-1,HC, CsA & IFN-γ,or which CsA was the most effective, by combination treatment with SA-1 to steroid and CsA, significant additive effects were noted in MCNS group. In conclusion SA-1 has a steroid and CsA sparing effect and could reduce side effects of steroid and Cas significantly if clinically applicated.
