Recently, many foreign researchers found that the tetrodotoxin-resistant voltage-gated sodium channel, Nav1.8, which is expressed only by unmyelinated small-diameter sensory neurons associated with nociception in dorsal root ganglion and trigeminal ganglion, is involved in pain pathways and play a key role. Thus it provides a new idea in pain research.

近年来，国外众多学者发现河豚毒素(tetrodotoxin，TTX)不敏感型(TTX-resistant，TTX-R)电压门控钠通道Na_v1.8与疼痛的关系极为密切，其仅分布在背根神经节(dorsal root ganglion，DRG)和三叉神经节(trigeminal ganglion，TG)中的与伤害性感受密切相关的无髓鞘的小直径感觉神经元胞体上，它为疼痛的研究提供了新的思路。

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.

结果显示，分类地位相近的三种甲虫脑结构大小相差悬殊：小青花金龟脑结构相对发达，蕈形体结构显著，具有发达的冠和叶，嗅叶发达；马铃薯瓢虫和榆紫叶甲的冠极度退化，嗅叶相对不发达；但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布，且反应模式相似，但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象，且在三种甲虫脑中的空间分布位置基本一致。

The activities of succinate dehydrogenase in hepatocytes, alkaline phosphatase and thiamine pyrophosphatase on the wall of bile canaliculi became obviously less.Both the activities and localizations of TPPase had changed. Some TPPase from the damaged lysosome-like vesicles and Golgi saccules of hepatocytes discharged into the cytoplasm. TPPase reaction product in some bile canaliculi decreased.

酶细胞化学技术显示肝细胞线粒体琥珀酸脱氢酶和毛细胆管壁上的碱性磷酸酶活性明显减弱或消失，焦磷酸硫胺素酶的活性及定位也发生了改变， TPPase从损伤的高尔基复合体及溶酶体样小泡漏出进入胞浆，部分毛细胆管壁上的TPPase反应物减少。

Results: Remarkable pathological changes were found in h ippocampus: Nissl bodies decreased or disappeared, cyton swelled. The water cont ents and the level of LDH and NO were increased in scalded rats. CNTF could rema rkably improve the pathological changes and reduce the increase of LDH, NO a nd the water contents.

结果：大鼠严重烫伤后，脑组织含水量增加，海马出现明显的病理变化，尼氏小体减少或消失，胞体肿胀，LDH和NO的含量增加；给予CNTF后，脑水肿、海马的病理变化有明显改善，并能降低 LDH和NO的含量。

The cytologic features of normal squamous epithelial cells can be seen at the center top and bottom, with orange to pale blue plate-like squamous cells that have small pyknotic nuclei.

在涂片的中央上方和底部我们可以观察到正常鳞状上皮细胞的细胞学特征，鳞状细胞呈圆形，胞浆呈橘黄色，小的淡蓝色的固缩核。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

Based on the measurement and data analysis of the nine groups containing forty-seven woods belonged to Theaceae genera of Guangxi,wood anatomical molecule s are identified.

对采自广西的9个组47种山茶属木材解剖分子进行了测定研究，研究表明，山茶属木材的各种解剖分子显示长度长、直径小、胞壁薄的特点，属于比较原始的种系。

In a-bout one third cells agglomerate chromatin localizes at the edge of nucleus, which shows apoptotic traits.

PCF处理的HaCaT细胞的超微结构损伤程度明显减轻，如胞浆内更少的空泡样结构和更多形态正常的细胞器，少见具有凋亡形态的细胞，未见凋亡小体等。
