Liposome encapsulation attenuated venenum bufonis induced vascular irritation in rabbit ear vein via regulating TLR/MAPK/NF-κB pathway

Venenum bufonis (VB) induced vascular irritation was related with the regulation of TLR/MAPK/NF-κB signaling pathway, and liposome encapsulation significantly attenuated VB induced vascular irritation while maintaining its anticancer activity.

[Effects of cinobufacini injection on contents of serum thyroid-stimulating hormone and adrenaline in rats]

OBJECTIVE

To observe the effects of cinobufacini injection on serum levels of thyroid-stimulating hormone (TSH) and adrenaline (ADR) in rats, and to speculate the property (cold or heat) of the drug.

METHODS

Thirty-two male Wistar rats were randomly divided into normal control group, cinobufacini injection group, cold syndrome group and heat syndrome group. The rats in the four groups were administered with normal saline, cinobufacini injection, and compound of traditional Chinese drugs with heat or cold property. The weights, and the serum TSH and ADR levels of the rats were measured before and after the interventions.

RESULTS

The weights of the rats in heat syndrome group markedly decreased after 14-day administration when compared with the normal control group (P < 0.05). There were no significant differences among the normal control group, heat syndrome group and the cinobufacini injection group. Although no statistical difference was noted, the serum TSH levels of the cold syndrome group and cinobufacini injection group were slightly lower than that in the normal control group after 14-day administration, and the heat syndrome group showed a slightly higher serum TSH level. After administration, the serum ADR levels of the cold syndrome group and cinobufacini injection group were significantly lower than that in the normal control group (P < 0.05), and the serum ADR level in the heat syndrome group was higher than that in the normal control group (P < 0.05).

CONCLUSION

Cinobufacini injection seemed to be able to suppress the thyrotrophin-releasing hormone-TSH-thyroxine system and sympathetic nervous system, matching up with the characteristics of the Chinese herbs of cold property. And the study provided initial experiment evidence for the conclusion that the property of cinobufacini might be cold.

Efficient killing effect of osteosarcoma cells by cinobufacini and cisplatin in combination

PURPOSE

To study the killing effects on osteosarcoma cells of cinobufacini and cisplatin in combination and the related mechanisms so as to explore the chemotherapeutic method with integrated traditional Chinese and Western medicines.

METHODS

Cinobufacini and cisplatin were applied to OS732 cells singly or jointly and survival rates were measured by MTT assay. Changes in cellular shape were observed with inverted phase contrast and fluorescence microscopy and apoptosis rates were analyzed with flow cytometry (FCM). Immunocytochemistry were used to examine the Fas expression of OS732 cells.

RESULTS

The combination of cinobufacini and cisplatin had the effect of up-regulating Fas expression and inducing apoptosis. The survival rate of combined application of 100 μg/ml cinobufacini and 1 μg/ml cisplatin on OS-732 cells was significantly lower than with either of the agents alone (p<0.01). Changes in cellular shape and apoptotic rates also indicated the apoptosis-inducing effects of combined application were much enhanced.

CONCLUSION

The combination of cinobufacini and cisplatin demonstrated strong killing effects on OS-732 cells which might be related to up-regulation of Fas expression.
