Objective:
To probe into the pathogenesis of rat mesangial proliferative glomerulonephritis (MsPGN) induced by anti-Thy1 antibody.
Methods:
Anti-Thy1 serum was produced, and then intravenously injected into Wistar rats for establishing an experimental model of MsPGN. The control group received intravenous injection of normal saline. Urinary volume and urinary protein were examined every other day. The IL-1, IL-6 and TNF contents of serum were detected by radioimmunoassay. Pathologic morphology of renal section was observed with micrscope and BI2000 Image Analysis System. The rats of model group were killed on the 1st, 3rd, 5th and 7th days.
Results:
No significant difference was seen between the model group and control group in regard to the volume of urine and in-take water (P > 0.05). The levels of urinary protein, IL-1, IL-6 and TNF in model group were significantly higher than those in control group at all time points (P < 0.001-0.005). Glomerular mesangium cells and matrix in the model group were obviously proliferative, compared with those in control group.
Conclusion:
It is suggested that cytokine plays an important role in the onset of MsPGN.
