ABSTRACT

Objective To establish a suitable model for therapeutic treatment on rats of anti-glomerular basement membrane nephritis. Methods Rabbit with rat glomerular basement membrane and freund’s adjuvant were immuned by multi-point subcutaneous injection biweekly, five times totally, and the antiserum was prepared. Experimental model for therapeutic treatment was established. Serum level of immune complex (CIC), intensity of immunofluorescence of glomerular basement membrane, lesion of kidney and glomerular basement membrane was measured by multiple intravenous injection of antiserum to rats to determine suitable experiment conditions including titer of antiserum, dose of antiserum, method and time of antiserum injection. The model was observed the efficacy using Gushen 2 as therapeutic drug. Results Rats with 4 mL antiserum (titer 1:4) by intravenous injection were immuned 4 times 3 d. Rat anti-glomerular basement membrane nephritis form on day 6, 8, and 10 since immunization; Pathogenic condition were relatively mild on day 6 since immunization and basically stable on day 8 and 10 since immunization. Verification tests showed that, Gushen 2 significantly reduced the 24 h urine protein excretion, relieved kidney lesion for 30 consecutive days, which had obvious therapeutic effect on rats with anti-glomerular basement membrane of nephritis. Conclusion Rats immuned with 4 mL antiserum (titer 1:4) by intravenous, immune points up to 4 times 3 d, rat anti-glomerular basement membrane nephritis model form which are suitable for therapeutic treatment of drug on day 8 since immunization.
