Abstract:
BACKGROUND: The essential component of Plumbago zeylanica Linn is plumbagin, which plays a role in anti-leukemia, antibiosis, antifertility, as well as cardiovascular. OBJECTIVE: To investigate the effects of Plumbago zeylanica Linn on the healing process of experimental rabbit fracture. DESIGN, TIME AND SETTING: Randomized control experiment of animal was performed at the Department of Pharmacology, Guilin Medical College between December 2006 and February 2007. MATERIALS: Eight New Zealand rabbits, 80 to 85-day-old, weighing 2.1-2.5 kg, half male and half female. METHODS: Eight rabbits were randomly divided into the control and experimental groups, with 4 animals in each group. Under sterile conditions, the experimental bone fracture model of rabbit was created by making a longitudinal incision in the medial of the middle portion of right foreleg, cutting off a point-foot radius with bone clamp, and suturing the incision. The rabbits in the experimental group were treated externally with the extraction of Plumbago zeylanica Linn in 50% of ethanol, twice a day for 15 days. The sodium chloride was administrated into rabbits in the control group. MAIN OUTCOME MEASURES: The serum alkaline phosphatase (S-ALP), Ca2+, P3+, K+, Na+, Cl-, liberation and total calcium of the rabbit were measured at 15 and 30 days after drug administration, X-ray of the bones were performed at the fracture healing. RESULTS: Compared with the control group, the fracture healing of the experimental group was faster, and the serum examinations showed that the serum Ca2+ levels of the experimental group was significantly increased by Plumbago zeylanica Linn, there had significantly differences between prior to and after drug administration (P
