Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

Methods:Fifty paired embalmed cadaveric humeri (twenty-five pairs:fourteen from male donors and eleven from female donors) were scanned in medial-lateral and anterior-posterior position according to the humeral retroversion by CT. Images of the humeri in the transverse planes at the lowest border of neck,20mm and 40mm distal of LBN(LBN-20、LBN-40), isthmus, head-neck anterior-posteriorwere obtained. Sixty-one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset, head position, head-shaft angle, head to tuberosity height, head thickness, curvature radius, articular surface arc, neck diameter, isthmus position, proximal and distal border of isthmus, maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes, including LBN, LBN-20,LBN-40 and isthmus.

Methods: The distal 1/3 of eighty humeri was scanned by 16 layer spiral CT. The morphologic features of the intramedullary bony prominence above the olecranon fossa were observed and described on coronal, sagittal and transverse section after three-dimensional reconstruction. Then the distal 1/3 of twenty humeri was splitted vertically along the coronal midline for observing the intramedullary bony crista.

A broad expanse of the river was turned to blood;1 in the middle distance the red hue brightened into gold, through which a solitary log came floating black and conspicuous;2 in one place a long, slanting mark lay sparkling upon the water; in another the surface was broken by boiling, tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest, was a smooth spot that was covered with graceful circles and radiating lines, ever so delicately traced; the shore on our left was densely wooded, and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun.

不远处红光闪成金黄；孤零零的一根原木在河中漂浮而来，呈一线醒目的黑色；河的一处，一条长长的斜影横落在水面上，闪闪烁烁；另一处，水面被翻滚的水波打碎，仿佛蛋白石放射的斑斓色彩；红彩最淡处是一片平静的水面，覆盖着优雅的环形和放射状的波纹，细腻如绘；河左岸是一片浓密的森林，一条长长的崎岖小径划破树林的一片荫翳，闪闪如银；一株光秃秃的枯树高耸于密林之上，仅剩的一杆青枝随风摇曳，像火焰闪耀在阳光洒下的一览无遗的壮美之中。

Results In healthy subjects, L2-L5 nerves were displayed clearly by MRN, with a round or ellipse ganglion of 3-6 mm in diameter, and smooth stick-like nerve root and trunk, 2-5 mm in diameter. The signal intensity was higher in ganglion than nerve root or trunk. 40% of nerve root sheath was surrounded by small amount of cerebrospinal fluid, Femoral nerve was displayed in all subjects, while only 83.3% of obturator nerve and 43.3% of lumbosacral trunk were manifested. Lamellar blurred hyper-signal intensity was seen around 80.9% of lumbar plexus in GBS, but none in CIDP.
