Dermonecrotic toxin (DNT), lipopolysaccharide (LPS), and lymphocytosis-promoting factor (LPF) were isolated from Bordetella pertussis and tested for neuroactivity. When injected intraperitoneally into rats, a dose of 0.13 mg of LPF per kg elevated the cyclic GMP level in cerebellum by approximately 70%, whereas DNT (0.5 mg/kg) and LPS (1.5 mg/kg) were without effect. This action of LPF on the central nervous system was dose dependent and did not require the administration of any additional agent, such as histamine.
从百日咳博德特氏菌中分离出皮肤坏死毒素(DNT)、脂多糖(LPS)和淋巴细胞增多促进因子(LPF),并对其神经活性进行了测试。当以每千克0.13毫克的剂量腹腔注射到大鼠体内时,LPF可使小脑环磷酸鸟苷水平升高约70%,而DNT(0.5毫克/千克)和LPS(1.5毫克/千克)则无此作用。LPF对中枢神经系统的这种作用具有剂量依赖性,并且不需要施用任何其他药剂,如组胺。
