The results indicated that under normal conditions, compared with into-pulmonary blood (IPB), in out-pulmonary blood (OPB) the functional PC increased and ATⅢ activity decreased significantly (P

Objective To measure the course of the mandibular canal in mandibula posterior area by cone-beam computed tomography ( CBCT ) , to provide a theoretical support for implant preoperative assessment. Methods Mandibular data of 65 people measured by CBCT were collected, measured the distance between mandibular canal around the bone wall and analyzed the differences by gender and the differences between the left and the right. Results The average distance of mandibular canal outer edge to the buccal bone plate by former backward in-creased gradually,at least in the area of the mental formen, at largest in the area of the mental foramen after 18 mm. The average distance between mandibular canal inner edge to lingual bone plate by former backward reduced gradually, at largest in the area of the mental foramen,at least in the area of the mental foramen after 18 mm. The average distance between mandibular canal upper edge to alveolar crest by former backward reduced gradually,at largest in the area of the mental foramen, at least in the area of the mental foramen after 18 mm. The average dis-tance between the edge of mandibular canal to the edge of mandible by former backward reduced previous,then in-creased, at least in the area of the mental foramen after 6 mm, at largest in the area of the mental foramen after 18 mm. All the results had no significant statistical differences between the male and the female, and had no significant statistical differences between the left and the right. Conclusion The trajectory of the mandibular canal from front to back is downward first, then upward in the mesial of the first molar in the vertical, and whose from the buccal side to the lingual side. That has significance for assessment before implant in mandibular posterior area.

Objective To optimize the medium for rhizomatous induction of Belamcanda chinensis in vitro. Methods By plant tissue culture technology, the effects of various carbon source, NAA, and active carbon at different concentration on the rhizomatous formation of B. chinensis in vitro were studied. Results MS+6-BA 2.0 mg/L+NAA 0.5 mg/L+6% white sugar was the optimal medium for the rhiz-omatous formation of B. chinensis in vitro. Active carbon should not be added to the medium. The germination rate of rhizomatous in vitro was 61.03% on the MS + BA 2.0 mg/L+3% white sugar. Conclusion Sugar concentration is the main factor of the influence on the rhizomatous formation of B. chinensis in vitro.
