Object To establish cell suspension culture system in leaves of seedling of Pueraria lobata (Willd.) Ohwi Methods The callus induced from leaf explants of P.lobata seedling were suspended in liquid medium. The time courses of cell growth and yields of puerarin and isoflavones were studied Results The log phase of the cell cultures' growth was from 1st d through 5th d. The dry weight accumulation reached highest on 8th d. The production of puerarin was highly coupled with the cell growth. The yield of puerarin reached highest on 8th d. However, the accumulation of total isoflavones was different from that of puerarin. The yield of total isoflaones reached the highest on 10th d Conclusion The yield of total isoflavones in cell suspension culture system is higher than that in wild plants, while the yield of puerarin is lower than that in wild plants

To resolve the problems of relativity translation variant and relativity rotation variant existed in the two medical images, combining the removing characteristics and rotating characteristics in image signal Fourier transform, a method of medical image registration combining with frequency domain and time domain is put forward based on the well-known Fourier property. The method decouples the estimation of rotation and translation. It determines rotation parameters based on amplitude spectrum correlation in frequency domain and estimation translation parameters based on intensity value correlation in time domain. The experimental results of nuclear medical image registration and multi-modality medical image registration show that this method is a very robust and fast registration method with high accuracy.

BACKGROUND: Clinical observation demonstrates that accelerated fracture healing or lower limb heterotopic ossifications always occur in patients with paraplegia. It indicates that peripheral nervous system may play an important role in fracture healing process.OBJECTIVE: To observe bone histomorphometery parameter, callus formation and biochemical change during the process of fracture healing of unilateral lower limb denervated tibia.DESIGN: Self-control animal experiment.SETTING: Tianjin Hospital.MATERIALS: Totally 36 six-month-old healthy male Wistar rats, with mean body mass of 210 g, were used in this experiment.METHODS: This experiment was carried out at Animal Experimental Center of Tianjin Hospital from March 2001 to March 2004. Denervated tibia fracture model and innervated tibia fracture model were made in the same rat. Animals were executed under anaesthetic status at week 2 and week 4 after fracture. Bilateral tibias were chosen to take radiografts.Biomachamical strength was measured and non-decalcification sections were prepared to perform bone histomorphometery observation.MAIN OUTCOME MEASURES: ① Comparison of wet weight of bilateral tibias and callus of rats between two groups after fracture. ②X-ray plain film scoring. ③ Biomechanical testing of tibial samples. ④ Histomorphological observation of fracture healing RESULTS: ① Wet weight of bilateral tibia and callus of rats in denervated group was much higher than that in innervated group at weeks 2 and 4 after fracture [(0.94±0.15) vs (0.76±0.14) g, (1.06±0.26)vs (0.81±0.10) g,P < 0.05]. ②In X-ray plain film scoring, callus formation was significantly increased in denervated group (P < 0.01). ③In biomechanical testing of three-point bending of tibial sample, callus intensity was significantly lower at weeks 2 and 4 after fracture in denervated group than in innervated group[ (9.88±8.49)vs ( 16.62±13.38 ) N, ( 12.77±7.55 )vs (20.19±10.60) N,P < 0.05]. ④Bone histomorphometery showed that compared with innervated group, mineralized bone trabecula width of denervated group was significantly reduced (P < 0.05), osteoid width was increased , osteoclast index and bone absorption area were significantly increased (P < 0.05), and there were no significant difference of fibroblast index and bone formation area between two groups; Compared with innervated group, mineralized deposition rate in the denervated group was significantly reduced (P < 0.05), the mature time of osteoid was elongated (P < 0.05).CONCLUSION: Peripheral nervous system may play an important role during early and middle period of fracture healing. Intact innervation is essential for normal fracture healing.
