The MBP content of telencephalon tissue in control rats were 78~82 礸/ml, there were no difference in all the 2 Gy irradiated, 1 week and 1 month after 10 to 30 Gy irradiated groups.

髓鞘染色显示30 Gy照射后6月大鼠在胼胝体区有较典型的脱髓鞘病变存在。10~30 Gy照射后1~6个月各组在超微结构上也有不同程度的髓鞘异常。

To clone new disease gene of CMT, many myelin and myelin-related gene had been analysised by homologue searching. Quaking mouse, one of the mutation mouse with the clinic feature similar to Trembler mouse (the gene mutation mouse of PMP22) with the characterization of demylination in both the central and the peripheral nervous system, its disease gene had just been cloned accession No.

为进一步克隆新的CMT致病基因，在分析出CMT已克隆的基因均为与髓鞘有关的基因后，通过筛选有关髓鞘基因，我们发现，quaking基因突变小鼠因髓鞘形成障碍而出现震颤，其中枢和周围神经均有脱髓鞘，类似于PMP22基因突变鼠"Trembler"的临床表现。

Abstract］ objective to improve the diagnosis of non-ossifying fiboma by analysing its x-ray feature.methods plain x-ray films was performed in all patients.x-ray finding in 8 cases with pathologically-confirmed non-ossifying were analyzed.results the clinical symptom was mild,the lesions occurred usually at the metaphysis of the long bones,the affected bones included femur（n=4）,tibia（n=3）,humerus（n=1）.cortical type was seen in 5 cases,presenting as unilocular or multilacular transparent areas with in the cortex or tightly beneath the cortex,the lesion had a sclerotic margin.which was more obvious at the marrow side.medullary type was seen in 2 cases.the lesion was located at the center of the bone and grew centrally.the tumor was manifested as unilocular or multilocular.tramsparent area with sclerotic border and the bone cortex became thinner with slightly expanding on 11 sides.conclusion plain radiography is the elementally means to detect this disease.based on the typical x-ray signs of non-ossifying fibroma combined with clinical data,correct preoperative diagnosis can be made in most cases.

目的 探讨非骨化性纤维瘤的x线表现以提高诊断水平。方法所有病例均摄有x线平片，分析经病理证实的8例非骨化性纤维瘤。结果临床症状轻，好发于下肢长骨干骺端或骨干，股骨4例，胫骨3例，肱骨1例。皮质型5例，表现为皮质内或紧贴皮质下的单层或多层透亮区，病变向骨内发展进入髓腔，周围有致密硬化带环绕，以髓腔侧明显；髓质型2例，病灶在骨内中央发展，显示为单房或多房透亮区，边缘有硬化，骨皮质菲薄，轻微向周围膨隆。结论 x线为最基本的检查方法，典型病例x线平片结合临床症状即可明确诊断。

The laboratory findings of a typical CCML patient comprised of peripheral blood leukocytosis, basophilia and eosinophilia,myeloid differentiation in different stages, and increased megakaryocytes. The immunohistochemical features of the CCML consisted of highly positive MPO and CD68, significant lowering of neutrophil alkaline phosphatase, positive for Philadel- phia chromosome or chimeric BCR/ABL gene, etc. But in most cases of juvenile CCML, the Philadelphia chromosome could not be detected.

临床表现以乏力、低热、贫血、肝脾及淋巴结肿大为主要特点；典型儿童慢性髓细胞白血病的实验室特点有白细胞计数高、嗜酸和嗜碱性粒细胞增多、骨髓不同阶段髓细胞分化和巨核细胞增多；免疫组化提示CD68，髓过氧化物酶，中性粒细胞碱性磷酸酶积分明显减低，Ph染色体或BCR/ABL融合基因阳性，而幼年型CCML的Ph染色体常为阴性。

Therefore, in the present study, a retrograde and anterograde experiments were made in the rat to address this issue. After injection of cholera toxin B subunit, a retrograde tracer, into Barrington's nucleus or D-region, some retrogradely labeled neurons were found in lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus of the lumbosacral spinal cord segments. Injection of biotinylated dextran amine into lamina I, sacral parasympathetic nucleus and dorsal commissural nucleus, respectively, a large number of BDA-labeled axon terminals were seen in Barrington's nucleus and D-region.

发现，将逆行示踪剂霍乱毒素 B 亚单位（ Cholera toxin B subunit； CTb ）注射到 Barrington's 核或 D 区后，在大鼠腰骶髓 I 层、骶髓副交感核和后连合核内分布有一定数量的 CTb 逆标神经元；将顺行示踪剂结合生物素的葡聚糖胺(Biotinylated dextran amine； BDA)分别注射到腰骶髓 I 层、骶髓副交感核和后连合核内后， Barrington's 核和 D 区内出现大量顺行标记的轴突终末。

Maxillary central incisors had a slightly greater pulpal blood flow values than maxillary lateral incisors. The flow values from 15 teeth with necrotic pulp or pulpless teeth were significantly lower than that from the control teeth. Before therapy the values from 16 deep caries teeth were all higher than that from the control teeth. After therapy, most (15/16) of those values decreased to normal in three days. The value of one tooth with deep caries remained high, and one week later, the pulp became necrosis.

由死髓牙测得的流量值显著小于正常对照。16颗深龋患牙治疗前牙髓血流量皆高于正常对照组，治疗后有15颗患牙的血流量很快降至正常，有1颗患牙在治疗后血流量无明显变化，最终发生牙髓坏死。

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1～3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3～6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3～6h afterinjury,then return to normal levels and continued to 24h after injury.

生前损伤组，可见广泛蛛网膜下腔出血，脑组织水肿，神经细胞肿胀，晚期神经元固缩；伤后1～3h见部分神经轴突不规则增粗、断裂，伤后6h断端膨大，伤后15h可见收缩球，至伤后24h更为明显；伤后3～6h可见部分神经髓鞘与轴突之间的间隙增宽，伤后15h髓鞘明显曲折，不完全附着在轴突两侧，甚至剥脱，持续到伤后24h；核周尼氏体减少在伤后24h才开始出现；同一部位的GFAP阳性细胞数目随损伤时间发生改变，先增多（最早在伤后0.5h），达到高峰后减少，其后又有增多趋势，但不同部位的GFAP阳性细胞数目增减的时间过程不尽相同，同时，大脑中的GFAP阳性细胞数目也有改变；伤后0.5h，可在脑干组织中见到Al和Fg阳性神经细胞，主要位于血管周围，阳性物在胞浆中呈弥散性分布，但部分细胞的阳性物仅分布于靠近胞膜的胞浆中而呈环状，随损伤时间延长，阳性细胞数目增多，反应强度增加；伤后3～6h，延髓及桥脑中的SYN阳性物面积减少，其后恢复到正常水平，并持续到伤后24h。

Results There was an extensive staining with both P2X2 and P2X4 receptors positive neurons and nerve fibers localized in medulla oblongata. It was mainly localization in the nucleus tractus solitarius,Ⅻ nucleus and ventrolateral medulla of medulla oblongata. It also scattered throughout rest of medulla.
