Abstract:
Objective: To explore the effect of immune reaction induced by alginate on parotid acinar cells in vitro. Methods: Rabbits were immunized from the conjugated alginate- BSA (1.0 mg/kg) by 40-days routine immunity method. ELJSA method was used to examine the titration (valence) of anti-alginate serum. Five groups (group A: contrast, group B: BSA, group C; alginate, group D: anti-alginate serum, group E; alginate + anti-alginate serum) were examined by MTT method at four time points( 1, 6,12 and 24 h). The growth and morphology of parotid acinar cells were observed under inverted phase contrast microscope and scanning electron microscope. Results: Antibody-serum was acquired by routine immunity method, and the titration (valence) of anti-alginate serum was 1: 400. MTT results showed that the proliferation of parotid acinar cells had been limited at 24 h( P <0.05), the other three time points showed no difference. Under inverted phase contrast microscope, a few of acinar cells whose membranes were destroyed after 12 h, some cell contents leaked out. The holes in membrane could be seen early at 6h under scanning electron microscope. Most of the acinar cells were broken at 24 h. Conclusion: The antibody-serum to alginate and immunized rabbit was acquired by routine immunity method. The immune reaction induced by alginate can destroy parotid acinar cells in vitro.
