Fig. 2A shows the apparent viscosity of the two MBH preparations containing 15% Poloxamer 407. It was found that the apparent viscosity of triptolide-loaded MBH was markedly lower than that of blank MBH preparation. Hence, the addition of triptolide decreased the viscosity of MBH. Further information gained on the thixotropy of the two MBH preparations is shown in Fig. 2B. The results of blank and triptolide-loaded MBH preparations were 3245.37 Pa/s and 3763.47 Pa/s, respectively. The addition of triptolide affected the interconnected network to a noticeable extent, but this did not damage the stability of this structure.
