Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors.
最终在兴奋性毒性(过度刺激神经元上的递质受体)、钙紊乱、炎症、能量和生长因子缺乏作用下,敏感的神经元发生萎缩、死亡。apoE4与Aβ和tau的异常聚集有关,还可能损伤线粒体和其他细胞骨架。Aβ、tau、apoE和synuclein与其他分子相互作用,影响多种神经活动和存活的信号转导途径。

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.
最后,易感神经元会萎缩直至死亡,原因可能有兴奋性中毒(神经递质对神经元表面受体的过度刺激引起),钙稳态失衡,炎症反应,能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合,可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应,也可调节不同信号级联反应,这些级联反应对于维持神经元活动性和生存性意义重大。

The gum atrophies to still cause the tooth dew outside the root, the surface of tooth root doesn't have tooth enamel quality, not only be easily worn away while brushing teeth once there being no the protection of guming, in the meantime to cold, hot and sour incitement very sensitive, the mouth cavity medical science is called "tooth essence allergy", people often mistaken for this kind of phenomenon to peep out tooth nerve to cause ache, and this is incorrect.
牙龈萎缩还导致牙根外露,牙根的表面没有牙釉质,一旦没有了牙龈的保护,不仅容易在刷牙时受到磨损,同时对冷、热、酸的刺激非常敏感,口腔医学称为&牙本质过敏&,人们常把这种现象误认为是露出牙神经导致疼痛,这是不对的。

Histologically, the seminiferous tubules contained numerous Sertoli cells and more Sertoli-spermatozoa complexes, accompanied by the depletion of Leydig cells with deeply stained nuclei. Mature spermatozoa were stored up in the epididymis, but only a few in the efferent ducts. In the second place was testicular atrophy(32/120; 26.7%). The seminiferous tubules showed moderate to severe inactivity of spermiogenesis with evidence of only spermatogonia, spermatocytes and Sertoli cells. The Leydig cells were obviously decreased in numbers associated with decrease of lipid droplets in their cytoplasms. Testicular hypoplasia was the third disorders(22/120; 18.3%). Only a few spermatogonia and Sertoli cells appeared without any spermiogenesis. The associated changes was decreased in Leydig cells and fibrous hyperplasia in the interstitium.Epididymal stones were sometimes found(12/120; 10%). Grossly, yellowish-white nodules with various sizes and firm in consistency were observed in the epididymis and the front efferent ducts. Microscopically, the epididymal ducts were dilated with voluminous spermatozoa storage, even showed calcification in severe cases. The deposited calcium salts were stained positively by Von Kossa and Alizarin red methods.Amyloidosis was also detected in 10 roosters(8.3%). Eosinophilic, homogeneous, amyloid-like substances were deposited mainly in the testicular interstitium and the periphery of blood vessels. These substances showed positive reaction by Congo red staining. Five roosters(4.2%)had Marek's lesions in the testis, epididymis and peripheral nerves with infiltration of pleomorphic lymphocytes. Only one case showed epithelial necrosis of seminiferous tubules accompanied by fibrous proliferation in the interstitium.
结果发现,在总共搜集的120个病例中,其中因年老所导致的产精力不佳为最多,占38例(31.7%),於镜下可见大量精虫黏附於Sertoli cell的表面,并可见Sertoli cell数量明显增多而Leydig cell明显减少,且其细胞核呈现浓染的现象,而在其副睪中仍可见到成熟精虫蓄留於管腔中,但在其输精管内却只有少量精虫存在;其次为睪丸萎缩,占32例(26.7%),镜下可见中度至重度无造精作用,其生精小管中只见到精母细胞、精原细胞及Sertoli cell存在,但Leydig cell数量明显减少且其细胞质内的脂质也明显减少;睪丸发育不全,占22例(18.3%),於生精小管内只见到精母细胞及少量Sertoli cell存在,不见造精细胞分化,於生精小管间质可见Leydig cell减少并伴随结缔组织增生;副睪结石,占12例(10%),肉眼下可在副睪及输精管前段见到黄白色大小不一的结节,触感坚硬,於镜下可见副睪管扩张并有大量成熟精虫蓄积,严重时可见钙化现象,以Von Kossa及茜素红染色均呈阳性反应;类淀粉沉著症,占10例(8.3%),镜下在睪丸间质及血管周围可见粉红均质样的物质沉积,以刚果红染色成阳性反应;马立克病,占5例(4.2%),镜下可在睪丸、副睪实质及周边神经内均可见到嗜碱性大小不一的淋巴样细胞浸润;睪丸坏死,占1例(0.8%),镜下可见生精小管上皮细胞坏死脱落及间质结缔组织增生。
