为了鉴定甜瓜属野生种酸黄瓜 (CucumishystrixChakr.)对南方根结线虫 [Meloidogyneincognit(Kofoid&White)Chit wood]的抗性 ,进而评估抗性向酸黄瓜与栽培黄瓜种间杂种的转移 ,选用了酸黄瓜、 4个栽培黄瓜材料、两种倍性水平的 3个... 为了鉴定甜瓜属野生种酸黄瓜 (CucumishystrixChakr.)对南方根结线虫 [Meloidogyneincognit(Kofoid&White)Chit wood]的抗性 ,进而评估抗性向酸黄瓜与栽培黄瓜种间杂种的转移 ,选用了酸黄瓜、 4个栽培黄瓜材料、两种倍性水平的 3个正反交杂种F1和 1个回交后代作为试材 ,在温室中进行抗性鉴定和筛选。结果表明 ,酸黄瓜对南方根结线虫具有高度抗性 ,而 4个栽培黄瓜材料均为高度敏感。酸黄瓜平均每株根系形成约 3个根结 ,栽培黄瓜材料每株根系的根结数超过 10 0个。酸黄瓜通过与栽培黄瓜的正反交 ,其抗性已被部分转移到杂种之中。当杂种作为供体亲本与栽培黄瓜进行回交时 ,抗性又被进一步转移到回交一代 (BCF1) 展开更多

We present the case of a 13-year-old boy undergoing scoliosis repair utilizing skull-femoral traction who developed sudden, sustained bradycardia and hypotension during scoliosis repair, associated with loss of somatosensory evoked potentials and motor evoked potentials to all four limbs. A diagnosis of spinal shock and hypovolemia was made after ruling out primary cardiac causes, sepsis, anaphylaxis and intra-spinal pedicle screw placement. Acute complications of surgical scoliosis repair are reviewed along with anatomy of the sympathetic nervous system. In this case spinal shock may have been due to hypovolemia as well as spinal cord manipulation during T12 vertebral column resection that was needed to effect scoliosis correction. Treatment included volume expansion and inotropic support. Anesthesiologists caring for these patients should be mindful of the possibility of spinal shock during correction of severe scoliosis, particularly when vertebral column resection is undertaken. 展开更多
