Abstract:
Objective: To investigate the synergistic antibacterial effect of Callicarpa nudiflora associated with Vancomycin Hydrochloride on the pneumonia model rats infected by methicillin-resistant staphylococcus aureus (MRSA), and to provide a safer and more effective treatment of clinical ideas for the treatment of infections caused by MRSA. Methods: Totally 80 NIH female rats were randomly divided into eight groups, ten rats as the control group, and 200 μL MRSA (1 × 108 CFU/ mL) bacteria was dropped in the left nasal cavity of the remaining rats to produce infected animal model. The administration with drug respectively by group was continued for 10 d. The common state including activity and intake of water and food were observed and noted. After administration for 10 d, the count of leucocyte, microbial load, and histopathological change of lung were observed. Results: Compared with the model group, the absolute value of leucocyte and microbial load of association of C. nudiflora and Vancomycin Hydrochloride were reduced signicantly (P < 0.05). The pathological damage alleviated significantly. Conclusion: Association of C. nudiflora and Vancomycin Hydrochloride has the synergistic antibacterial effect towards MRSA, which can improve the curative effect of antibiotics and shorten the period of treatment.
