The Study on the Effect of Ikryung-tang(yiling-tang) and Ikryung-tangkamibang(yiling-tangjiilweifang) on Rats with Nephrosis Induced by Puromycin Aminonucleoside

익령탕과 익령탕가미방이 Puromycin Aminonucleoside로 유발된 백서의 현증에 미치는 영향

Objectives : This experimental study was performed to prove the effect of Ikryung-Tang (yiling-tang; IRT) and Ikryung-tangkamibang (yiling-tangjiaweifang; IRT I, IRT II) on rats with nephrosis induced by a single intravenous injection of puromycin aminonucleoside (PAN). Methods : The effects of IRT, IRT I and IRT II on PAN nephrosis were evaluated by measuring the gene expression of IL-4, $IFN-{\gamma}$ and the concentrations of IgE, albumin, total protein, cholesterol, triglyceride, creatinine, and BUN in the serum and the volume & amount of protein of the 24hrs' urine. Results : In the gene expression linked T cell specialization, IRT II inhibited IL-4 and IgE but IRT and IRT I showed no significant difference compared with control group. On the other hand, IRT, IRT I and IRT II increased $IFN-{\gamma}$ compared with the control group. In the urine protein, serum albumin, total protein, BUN, and creatinine, IRT I especially showed more. significant effect than other groups. In the serum cholesterol and triglyceride, IRT II especially showed more significant effect than other groups. In the urine volume during 24 hrs, IRT especially showed more significant effect than other groups. Conclusions : According to the above results, it is suggested that IRT is effective for the treatment of edema, IRT I is effective for the treatment of hypoproteinemia and kidney dysfunction, IRT II is effective for immune modulation and the treatment of cholesteremia. Therefore IRT, IRT I and IRT II seem to be available for treating nephrosis in clinical practice.
