据报道,黄腐酸钠尚有止痛作用,能解除风湿性关节痛,甚至恶性肿瘤患者的顽固性疼痛也能缓解。我们拟通过黄腐酸对小白鼠痛阈影响的实验性研究,以探讨该药是否具有止痛作用。实验方法采用经我们改进了的热板法,观察小白鼠在腹腔内注入黄腐酸钠前后的痛阈变化。具体方法如下:在恒温水浴锅内的水面上,放置一块19×38cm的锡板,调节水浴锅的 According to reports, sodium sulphurate still has analgesic effect, can relieve rheumatic arthralgia, and even intractable pain in patients with malignant tumor can also be alleviated. We intend to investigate the effect of fulvic acid on the pain threshold of mice to investigate whether the drug has analgesic effects. Experimental methods We used the modified hot plate method to observe the changes in the pain threshold of mice before and after intraperitoneal injection of sodium fulvate. The specific method is as follows: Place a 19×38cm tin plate on the water in the constant temperature water bath, and adjust the water bath
