| Popis: | Objective To discuss the repair effect of lyophilized platelet lysate (PL) products on articular cartilage injury model of rats. Methods A total of 25 SD rats were injected with typeⅡcollagenase at the right knuckle articular cavity respectively on day 1, 3 and 5 of experiment, and the modeling conditions were observed 14 days after the last injection of collagenase. The SD rats with successful modeling were randomly divided into three groups, and were injected with lyophilized PL [Group A, 1 mL/(mouse·time)], PL [Group B, 1 mL/(mouse·time)], and normal saline[Group C, 1 mL/(mouse·time)]. The above three substances were injected with corresponding drugs on day 0, 7, 14 and 21 of experiment based on the grouping conditions, and the changes of knee joint diameters of the rats from the three groups were observed and compared. On day 14 and 28, one rat in each group was randomly killed and two knuckle articular cavities of each were taken for tissue sampling, using hematoxylin-eosin staining (HE) and immunohistochemistry. Results After 14 days of modeling by injection of type Ⅱ collagenase, the proportion of successful modeling in rats was 84% (21/25), with the knee joint diameter (mm) before and after modeling at 12.84±1.14 vs 14.11±1.17(P |
