Abstract:
Objective To compare the effects of three kinds of fixative solutions on paraffin section of mouse lens tissue and optimize the fixing?method of paraffin section in mouse lens tissue. Methods Three kinds of conventional fixatives were selected for the test ,including the conven?tional Davison’s solution,modified Davison’s solution and 10%neutral buffered formalin. Mice eyeball tissues were fixed with three different fixa?tives,embedded,sliced and then stained with HE method. The paraffin slices were observed under the light microscope. Results The structures of lens and retina fixed in conventional Davison ’s fixative solutions were clear and intact ,and the cells were arranged regularly and compactly. There was no eyeball distortion,contraction and retinal detachment in the eyeballs fixed in modified and conventional Davison’s fixative solution. However,the ones fixed in 10%neutral buffered formalin showed eyeball distortion and contraction,space and spherules. Conclusion The mice lens slides made from tissues fixed by conventional Davison ’s fixative solution are better than fixed by modified Davison ’s fixative solution and the 10%neutral buffered formalin fixed ones.
