  retinal
Best-corrected visual acuity, intraocular pressure, retinal thickness and FFA were observed.
      
At the early stages of retina development, the neuroepithelial cells divide synchronously, thus leading to the accumulation of a certain number of the retinal rudiment cells.
      
Synchronous divisions precede the asynchronous ones, when the differentiation of the retinal cells is initiated.
      
The multipotent cells of the retinal ciliary-terminal zone and cells of the pigment epithelium in the eye periphery provide for the growth of amphibian and fish eyes during the entire life of these animals.
      
The main event of retinal regeneration in newts is the transdifferentiation of the pigment epithelium cells.

Trends in recent research on trace elements in man are briefly reviewed,mainly presenting the distinctive features and drawbacks of different microanalytical techni- ques and the correlations between trace elements in man and cardiovascular disesaes, cancer,ophthalmic diseases and other maladies. In this review,quite a number of microanalytical techniques are mentioned and presented,e.g.arc emission spectrometry,neutron activation,mass spectrometry,ato- mic absorption spectrometry,X-ray luorescence spectrometry and arc emission- flame emission.Using elemental localization techniques,the detail ultrastructure of cell and subcell level can be clearly observed,and quantitative analysis of ele- ments in each minute field could also be carried out,such as electron microprobe analysis and proton induced x-ray emission,etc.There are three kinds of samples which can be utilized from the analytical view point:body fluid,soft tissues and hard tissues,of which,under many circumstances,hair being an ideal microanalytical sam- pling source. A large number of studies revealed that low concentration of chromium is oneof the etiological factors of arteriosclerosis,high concentration of cadmium may indu- ce hypertension,while selenium deficiency seems to result in Kokuzan disease as well as few other cardiovascular diseases.High morbidies of cancers in many re- gions throughout the world were correlated with concentrations of different trace elements in water,soil and grain.Metals leading to cancers have drawn the world's- attention.Animal experiments showed that selenium,in different concentrations, can act either as a cancer inducer or an inhibitor.Deficiency of zinc,copper and selenium can result in high degree myopia,retinal diseases,glaucoma and cataract, etc.Furthermore,trace elements are also related to carbohydrate metabolism,low IQ and learning disability,as well as some hereditary anomalies. The action of trace elements in human body are quite complex,many pathoge- nic mechanisms are not clear yet.

微量元素与人体健康和疾病的关系十分密切。本文综述微量元素的研究概况,各种微量分析技术的优点和局限性以及人体微量元素与心血管疾病、癌症、眼病及其它疾病之间的关系。目前世界上已有多种微量元素检测方法。本文介绍了弧光发射光谱测定法、中子活化分析、质量光谱测定法、原子吸收光谱测定法、X 射线荧光光谱测定法和弧光发射—火焰发射等微量元素分析技术。此外,元素定位技术既可做细胞与亚细胞水平的超微结构观察,又可测定该微小区域所含的元素种类和含量,如电子探针显微分析技术、质子发射 X 射线分析等。分析所用的标本可分为体液、硬组织和软组织三种,人发也是微量分析的理想标本。大量研究表明,低铬是动脉粥样硬化的病因;镉过多引起高血压;低硒导致克山病或其它心血管病。世界上许多地区的癌症高发与当地水质、土壤及粮食中微量元素含量有关。目前,金属致癌已引起全世界的关注。动物实验表明,在不同浓度下,硒一方而可致癌,另一方面又可作为癌肿抑制剂。微量元素锌、铜、硒缺乏可致高度近视、视网膜病变、青光眼、白内障等多种眼病。此外,微量元素还与糖代谢、智力和学习能力低下以及某些遗传性疾病有关。微量元素在体内的作用相当复杂,许多发病机理迄今不明。

A series of laser radiation experi-ments upon Chinchilla rabbits forone or 1/8 seconds was performed usi-ng a single membrane righthand (ordeztral) fixed point He-Ne laser radi-ation apparatus.The radiation dosagewas divided into 5 and 6 dosage groups,each having 30 points irradiated.Thelaser density upon the rabbit's retinawas measured when the retinal injurywas 50% as the ED50.It is recommen-ded that a maximum allowable dosageof He-Ne laser radiation will be fi-xed at 8.76×~(-3) w/cm~2 per second or13.0×10~(-3)...

本实验用单模氦氖激光器在定点照射仪下对青紫蓝免进行1秒和1/8秒照射,照射剂量分别为6个和5个剂量组,每组剂量照射30个点,得出兔眼视网膜损伤机率为50%时角膜处激光功率密度(即ED_(50)),并提出我国氦氖激光最大允许照射剂量的建议值,即1秒照射为8.76×10~(-3)W/cm~2;1/8秒照射为13.0×10~(-3)W/cm~2。

By means of indirect hemagglutination (IHA) and enzyme-linked immunosorbent assay (ELISI) ,one hundred and three patients with ocular diseases were examined serologically for toxoplasma infection. The positive criteria were:titer af IHA antibody ≥1:32 and titer of ELISA antibody≥1:200. In the present study,there were 6 positive cases of IHA and 9 positive cases of ELISA respectively and 25 positive cases of both IHA and ELISA. The total rate of infection wss 38.8% (40 of 103 cases). In Patients with uveitis,...

By means of indirect hemagglutination (IHA) and enzyme-linked immunosorbent assay (ELISI) ,one hundred and three patients with ocular diseases were examined serologically for toxoplasma infection. The positive criteria were:titer af IHA antibody ≥1:32 and titer of ELISA antibody≥1:200. In the present study,there were 6 positive cases of IHA and 9 positive cases of ELISA respectively and 25 positive cases of both IHA and ELISA. The total rate of infection wss 38.8% (40 of 103 cases). In Patients with uveitis, retinal detachment, and congenital ocular diseases, the positive rates of infection with toxoplasma were 27.5%, 22.5% and 17.50% respectively, higher than in patients of other ocular di-seases. Basing upon the above data the relationship between some ocular diseases and toxoplasma infection in Jiangxi province may be understood. It is suggested that examination by IHA and ELISA simultaneousely may increase the detectable rate of toxoplasma infection in ocular diseases. This method may be used in early diagnosis.

采有间接血凝试验(IHA)和酶联免疫吸附试验(ELISA)对103例眼科患者进行弓形体感染血清学检测。阳性标准:IHA抗体滴度≥1:32;ELISA抗体滴度≥1:200。本组IHA阳性6例,ELISA阳性9例,两项皆阳性共25例,总感染率达38.8%(40/103)。以色素膜炎,视网膜脱离,先天性眼病感染弓形体的阳性率为高,分别占27.5%,22.5%,17.5%。据此可了解江西地区某些眼病与弓形体感染的关系。提出IHA与ELISA同时进行检测,可提高眼病弓形体感染的阳性检测率,可用于早期诊断。
