Abstract:
Objective To detect the effect of the antiphospholipid antibodies on the Schwann cells in vitro and to find if the Extract of Ginkgo biloba 761(EGb761)has any protective effects.Methods The immunoglobulins(Ig)were extracted from the serum of the patient with autoimmune polyneuropathies and those with controls.Ig only or Ig plus calf serum(served as complement)were added into the culture solutions of the Schwann cells.The density of the cell in one high power field,the cell perimeter and area were detected and compared to those blank and those controls.Results The shape of the Schwann cells in both the Ig and Ig plus calf serum solution were greatly changed.The densities of the cells in them were both lower than the blank ones,with more severe in the cells with calf serum.There was no significant different between the solutions with or without EGb761.Conclusion Ig from the patients with autoimmune polyneuropathies could attack the Schwann cells in vitro,with the existence of complements,the destruction was even more severe.No protection of EGb761 could be found in these situations.
