Abstract:
OBJECTIVETo observe the effects of Qingkailing injection on RBL-2H3 cell degranulation and histamine release, and discuss the possible mechanism of anaphylactoid reaction induced by Qingkailing injection.
METHODRBL-2H3 cells were incubated with Qingkailing injection for 30 min. Then the morphological changes of cells were observed by transmission electron microscopy. Cell degranulation rate was detected by Alcian blue dye assay, Annexin V binding assay and beta-hexosaminidase assay, and cell histamine release rate was detected by ELISA.
RESULTDifferent concentration of Qingkailing injection can induce the typical morphological changes in RBL-2H3 cell with degranulation. The rates of degranulation and histamine release in Qingkailing injection treated cells were significantly increased and dose-dependent.
CONCLUSIONRBL-2H3 cell degranulation and histamine release can be induced by single administration of Qingkailing injection, and then induced anaphylactoid reaction, which may be one of the possible mechanisms of serious adverse induced by Qingkailing injection for the first administration in clinic.
