| 背景资料 | Phenytoin is a hydantoin derivative and a non-sedative antiepileptic agent with anticonvulsant activity. Phenytoin potentially acts by promoting sodium efflux from neurons located in the motor cortex reducing post-tetanic potentiation at synapses. The reduction of potentiation prevents cortical seizure foci spreading to adjacent areas, stabilizing the threshold against hyperexcitability. In addition, this agent appears to reduce sensitivity of muscle spindles to stretch causing muscle relaxation. |

文献和实验Clonality - X Chromosome Inactivation Assay
can utilize X chromosome inactivation (methylation) to determine the clonality status of a tumor or premalignant lesion in females. The technique is based on a methylation-sensitive restriction enzyme and analysis of a polymorphic locus on the X chromosome
Clonality - X Chromosome Inactivation Assay
Clonality - X Chromosome Inactivation Assay This method was successful in our lab using prostate tissue and for our specific objectives. Investigators must be aware that they will need to tailor the following protocol for their own research
骨严重吸收，颏孔移位于牙槽表面，下颌管上壁仅为一菲薄骨板，此时宜采取去除下颌管上壁后解剖神经血管束的方法。 【适应证】 下颌全口牙缺失或一侧牙缺失，下颌牙槽严重吸收（下颌骨形态学分级为d、e者），颏孔移位于牙槽表面，且颌骨质量良好者（4级为禁忌）。 【术前准备】 ⑴常规术前准备" ⑵拍下颌曲面断层ｘ线片或下颌侧位片，观察下颌骨形态、质量，测量颏孔位置。 ⑶备好微型骨锯、骨钻及骨凿。 ⑷向患者预先说明，因为手术创伤可发
