Abstract:
The comparison on evaluating blood stasis syndrome in sleep deprived rats was carried out by using R, G, B image analysis of Tongue and palm as well as auricle, palm surface laser Doppler flow perfusion. The experiment was performed by means of a small platform on the water environment for sleep deprivation. The rats were weekly weighed at fixed time, and their macroscopic signs were observed; and their tongue and palm images of the control and model group were respectively collected by the SLR camera at the 2nd, 4th and 6th week. Then the color saturation analysis was performed by means of proofreading with the standard colorimetric card. At the same time, the laser dopper flowmetry was used to analyze the perfusion of auricle and foot flow in rats. It turned out that there was no significant difference in the R,G,B value of the tongue and palm in rats between normal group and model group at the first stage(at the 2nd week), so were the perfusion of auricle and foot flow in rats. But at the second stage (at the 4th week), the R value of tongue in model group rats was obviously lower than that in normal group(<0.01), and the other value (G,B) of tongue in module rats had a decease tendency, but there was no statistical significance. However, the perfusion of left and right auricle flow in model group rats were dramatically decreased as compared with the normal group(<0.01); there was still no significant difference in the perfusion of the palm between two groups. It was found that R,G,B value in model group had a lower trend as compared with the control group of the tongue and palm images at the third stage (at the 6th week), but no statistically significant difference. The perfusion of left and right auricle flow in model group was constantly decreased as compared with the normal group(<0.01).Right and left foot blood flow was lower than the normal group, but no statistically significant difference. We can safely conclude that the results of the R, G, B values of the tongue in rats could objectively reflect the characteristics of the rats with blood stasis syndrome, which were consistent with the diagnosis of clinical tongue image. As a method of microcirculation evaluation, the surface laser doppler perfusion of auricle can exhibit the characteristics of blood stasis in model rats, but also was more objective and reproducible. Therefore, the combination of R, G, B value of tongue as well as auricle laser doppler blood flow is more beneficial to the objective evaluation of index in the later study of traditional Chinese medicine blood stasis syndrome model.
