Abstract
Purpose: To investigate the effect of diagnostic ultrasound on corneal apoptosis in rats.
Methods: 24 male rats were randomly divided into 4 groups: control group, 10, 20 and 30 min group. The eyeballs of rats were irradiated continuously for different time lengths by Siemens ACUSON S2000 color Doppler ultrasound diagnostic instrument. 24 hours later, the animals were killed and the corneas were taken for Tunel apoptosis detection. The apoptosis rates of corneal epithelial cells, stromal cells and endothelial cells were calculated.
Results: Apoptotic cells were detected in corneal epithelial cells, stromal cells and endothelial cells of normal rats. There was no significant difference between the 10 min group and the control group (P>0.05). The apoptosis rate of 20 min and 30 min groups was significantly higher than that of the control group. With the extension of irradiation time, the apoptosis rate of corneal epithelial cells, stromal cells and endothelial cells increased.
Conclusion: 20 min of rat eyeball irradiated by diagnostic ultrasound can increase the apoptosis of corneal cells, and the apoptosis is aggravated with the prolongation of ultrasound irradiation time.
