Haversion system was clearly observed and matured bone tissues filled the ceramic pores and interconnected with each other. All the result suggested that, taking advantage of"living organic culturing medium"in vivo, culturing composite that consisted of autogenous periostea and biomaterials should be an effective approach to obtain satisfactory bioactive bone substitutes which have the potential to repair load-bearing bone defects clinically.

The descriptive studies can not only help us recognize the institutional characteristics of REET diffusion in rural China, but also help us interpret the success of the REET diffusion in rural China.

Furthermore, the knowledge accumulated on the nature of the innovation diffusion process is still rather limited and without a satisfactory theoretical framework. Based on microeconomics, games theory, and environmental economics, a general economic model of REET diffusion is established in this thesis, which combines the market equilibrium and the Stackelburg equilibrium.

These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.
