[Effect of psoralen on rat osteoblasts injuries induced by TCP wear particles in vitro and its mechanism].

To investigate the effect and mechanism of psoralen on calvarial osteoblasts injuries caused by tricalcium phosphate (TCP) wear particles in vitro. Primary osteoblasts were obtained from the calvaria of neonatal SD rat by the series of digestion and were identified with ALP staining. Calvarial osteoblasts were treated with TCP wear particles for 48 h to establish the in vitro model of osteoblasts injuries.

[Rapid determination of metallothioneins in foods by capillary zone electrophoresis].

A rapid method for the analysis of metallothioneins (MT) in foods by capillary zone electrophoresis(CZE) was developed. Two isomers of MT (MT1, MT2) in foods were separated and determined. After a series of optimization, the separation and determination of MT1 and MT2 were obtained within 10 min by using the phosphate buffer system consisting of 0.
