It is shown for the first time that HA coating can significantly enhance the adhesion and proliferation of rabbit corneal fibroblast in comparison with that of pure Ti.
      
We studied 56 biopsy samples of conjunctiva and 50 corneal discs excised from 28 patients with acquired keratoconus cornea.
      
Necrobiotic changes have been revealed in epithelium of the corneal discs going by the pathways of apoptosis-programmed cell death-and oncosis-initial edematic stage of necrobiosis.

Corneal endothelium of 321 normal coneas were photographcd in vivo with the non—contact clinical specular microscope and the relationship between cell density,cellmorphology and age was studied.The results indicated:(1)the higer the cell density,the more resemblances the cells had to homomegethous;(2)polymegetism of the endothelial cells increa- sed with age;(3)the cell density decreased with age in homomegethous and polymegethous endothelium but the decrease in homomegethous cells was more obvious than...

用非接触型镜面反射显微镜对321只正常眼进行活体角膜内皮照相,研究细胞密度、细胞形态和年龄的关系。结果表明:(1)细胞密度越高、细胞形态越接近同形细胞;细胞密度越低,细胞形态越接近多形细胞。(2)细胞的多形性随年龄的增加而增加。(3)多形细胞和同形细胞二者的细胞密度均随年龄的增加而下降,但同形细胞下降的幅度较多形细胞明显。

Corneal graft reaction is the main cause in corneal graft failure. To study the immunology of corneal graft is important. This paper reported animal models of corneal graft reaction which were produced by penetrating corneal homograft in rabbits after sensitizing to donor skin. It described the course after corneal graft and skin graft, clinical features of graft rejection , making specimens for light microscopy, SEM and TEM, the histopathologic observation of the reaction cornea of the experimental group and the clear cornea of the control group.It was found that in the control group,the clear grafts appeared similar to the normal cornea except that a scar had formed between the donor and recipient tissue.While in the reaction eyes many new vessels invaded the grafts and many infiltrating cells appeared in the grafts. The cells were lymphocytes, phagocytes, plasmacytes, polymorphonuclear leucocytes and fibroblasts. The grafts were damaged to different degrees.The recipient's corneas were only attached by some infiltrating cells but the tissue were not hurt. We discussed the problems about the animal model, the special feature of the reaction, the relationship between the pathology and immunologic mechanism and function, the vascular effect in graft reaction.It is believed that the clinical features and pathologic alterations of the experimental group conformed to classical specific immunologic reaction. This reaction was mainly a cellular immunity and also involved the humoral immunity.

角膜移植排斥反应现已成为角膜移植手术失败的主要原因,研究角膜移植免疫反应具有重要意义。本文报告了用同一供体皮肤移植引起兔同种穿透性角膜移植排斥反应的动物模型,描述了角膜移植术后和皮肤移植术后的经过,排斥反应的临床表现,组织学标本,包括光镜、扫描电镜和透射电镜标本的制作方法,重点报告了排斥反应实验组的角膜和对照组透明角膜的组织学观察结果。发现对照组的透明角膜,除了在供、受体组织交界处形成疤痕外,植片和受主角膜表现与正常角膜相同。而在发生排斥反应的角膜,则有大量新生血管侵入,植片有大量的浸润细胞,这些细胞主要是淋巴细胞,还有巨噬细胞、浆细胞、多形核白细胞、成纤维细胞等。植片组织遭到不同程度的损害,受主角膜除了有新生血管生长和有少量浸润细胞附着以外,没有受损。本文讨论了有关动物模型、排斥反应的临床特征、病理组织学与免疫机理及功能的联系,新生血管在排斥反应中起的作用等问题。我们认为本组实验动物模型的临床表现和组织学改变均符合典型的特异性免疫反应。这种反应以细胞免疫为主,亦有体液免疫参与。血管在免疫排斥反应的传入、传出弧中均超重要作用。

Tong-mai-ling has been used by us with success clinically in the treatment of superficial corneal scars since 1975. Animal experimentations were performed to Investigate the mode of action of the drug from 1976 through 1980. Studies commenced after corneal scars were successfully produced in both eyes of 10 rabbits. Tong-mai-ling was instilled to the left eye of each rabbit. 3 times a day. and injected subconjunctivally once a week, for 3 months, with the right eye serving as control. At the end...

Tong-mai-ling has been used by us with success clinically in the treatment of superficial corneal scars since 1975. Animal experimentations were performed to Investigate the mode of action of the drug from 1976 through 1980. Studies commenced after corneal scars were successfully produced in both eyes of 10 rabbits. Tong-mai-ling was instilled to the left eye of each rabbit. 3 times a day. and injected subconjunctivally once a week, for 3 months, with the right eye serving as control. At the end of 2 weeks after completion of treatment, scars of the treated eyes were found to be diminished both in size and thickness, and the stromal cells became smaller and more slender, arranging in a more orderly fashion. The thickness of the cornea became normal or nearly normal too. and its acid polymu-cosaccharide content declined to normal as well. Scars of the non-treated right cornea showed no change, and the stromal cells were found to be increasing in number and size and irregularly arranged. The thickness of scar and neutral polymucosaccharide content of the untreated corneas were also found to be increased.The above observations seemed to illustrate that Tong-mai-ling has its action mainly on the stromal cells of the corneal scar tissue. The drug appeared to have a certain inhibitory effect on the proliferation of the collagen-forming cells and synthesis of collagen fibers, and induced the recovery of the lowered acid polymucosaccharide content around the collagen fibers.

以家兔制作角膜瘢痕模型后,左眼用通脉炅治疗,3个月后,角膜瘢痕缩小、变薄,角膜基质细胞体积小而细长,排列较规则,角膜厚度正常或接近正常,间质中酸性粘多糖接近正常。作为对照组的右眼瘢痕无明显变化。认为通脉灵治疗角膜瘢痕的有效机理主要是影响角膜基质细胞的数量和功能。药物对胶原形成细胞的增殖及胶原纤维合成有一定抑制作用,并能使减少的胶原纤维周围的酸性粘多糖恢复。
