In this paper, effects of ultravielet irradiation on cataract of animals with trinitroluene (TNT) toxicant exposured were reported. The incidence of cataract on the group (A) TNT toxicant exposur- ed and the group (B) ultraviolet irradiation were 28.6% and 33.3%, respectively. The group (C) TNT toxicant exposured with ultraviolet irradiation was 57.1%, and the incidence increased about one time compared with group (A) or group (B). The path- ological changes of tissue structures of crystalline lens by light...

The incidence of cataract on the group (A) TNT toxicant exposur- ed and the group (B) ultraviolet irradiation were 28.6% and 33.3%, respectively. The group (C) TNT toxicant exposured with ultraviolet irradiation was 57.1%, and the incidence increased about one time compared with group (A) or group (B). The path- ological changes of tissue structures of crystalline lens by light microscopy or electromicroscopy in group (C) was more obvious than group (A) or (B), Authors considered that harmful factors of ultravio- let and TNT had combied effects to the incidenc- e of cataract.

单纯三硝基甲苯(TNT)染毒动物组和单纯紫外线辅射组动物白内障发生率分别为28.6%和33.3%。TNT染毒加紫外线照射组为57.1%,发病率增加近1倍。光镜和电镜观察,TNT染毒加紫外线照射组动物晶状体组织结构病理改变明显重于上述两组。可以认为,紫外线和TNT两种有害因素共存时,对白内障的发病有协同作用。

METHODS 12.7 kb chicken vimentin gene was microinjected into the male pronuclei of ICR mice. The injected embryos were transferred to pseudopregnant recipient females and several transgenic mice were generated. The cataract transgenic mice strains were established by cross breeding.

AIM To observe the cataract development and the histological changes of the lenses in the vimentin transgenic mice. METHODS 12.7 kb chicken vimentin gene was microinjected into the male pronuclei of ICR mice. The injected embryos were transferred to pseudopregnant recipient females and several transgenic mice were generated. The cataract transgenic mice strains were established by cross breeding. The cataract development was examined with slit lamp and the histological changes were observed with light microscope. RESULTS In three generations, 20 mice developed cataracts. The cataract appeared from 4 to 8 months after birth. Cortical cataracts were noted in 18 mice and nuclear ones in 2. Eight mice were unilateral and 12 were bilateral,which occurred simultaneously or subsequently. The severity of cataract increased with age. Under light microscope, the lenses were found to have irregular arrangement of epithelial cells,denucleated fiber cells in the anterior and posterior cortex, disturbance of the bow configuration, a tendency for the posterior pole of the lens fiber cells, and the swollen and ruptures of lens fibers. CONCLUSION Cataract in vimentin transgenic mice tends to appear between 4 to 8 months after birth. The lens opacity increases gradually with the age of the mice. The abnormal growth and differentiation of the lens epithelial cells may result in cataract formation.

ObjectiveTo observe the histopathological changes in the iris and ciliary body and a new intraocular lens(IOL) implantation in rabbits after lens extraction.MethodsIOLs were implanted into one eye of 16 rabbits.The three needles were passed through the corneoscleral limbal incision across the anterior chamber,posterior to the iris,through the ciliary body and out through the sclera at the 4,8 and 12 o'clock position.The three sutures were an interval of 120° and 0.5~1 mm behind limbus.The limbal incision was interrupted by nylon wire.The eyeballs were extracted at 1,2 weeks and 1,2 months postoperatively.The eyeballs were examined histopathologically by light microscope,scanning electron microscope,and transmission electron microscope.ResultsClear cornea and anterior uveitis,no hemorrhage were observed by slit lamp microscopy in one week.The inflammation changes were localized to iris,ciliary body,sclera.The growth of fibroblast cells and fibrous tissue on the surface of an IOL can be observed.The needle was situated in the ciliary sulcus in 17 cases,in ciliary processes in 19 cases,and in pars plana in 12 cases through ciliary body.The polypropylene(prolene) sutures weren’t intermixed with tissues.IOL was supported by the three sutures.IOL was very good in stability.ConclusionThe new IOL protocol showed good in histocompatibility.and the study can be considered a decent experimental reference for possible clinical applications.
