[The attack of different proteases on isolated zonular fibers (author's transl)].

Some proteases, i.e. trypsin, alpha-chymotrypsin, thermolysin, proteinase K, alpha-amylase, collagenase, and papain were investigated on their effect on isolated zonular fibers. All these enzymes but collagenase were zonulolytic active. An attack on the ground substance of the fibers by substances solving glycosaminoglycans and proteoglycans (hyaluronidase, EDTA, guanidinium chloride, H2O2) showed an increased effect of the enzymes used. These results suggest that the interfibrillar matrix has a protective function on the zonular fibers.

[The proof of different types of collagen in the bovine eye (author's transl)].

Characteristically stained polyacrylamide gels can be obtained by disk-electrophoresis in acid medium of several tissues of the bovine eye. The technique permits to prove different types of collagen in the eye, and allows the differentiation and identification of the tissues. By these results the different tissues of the eye can be divided into three groups. 1. Tissues showing two alpha collagen components in polyacrylamide gel (cornea, sclera, iris, ciliary body, anterior lens capsule, and the pigmented epithelium of the retina). 2. Tissues possessing one alpha component only (zonula fiber and vitreous body). 3. Tissues which show neither the alpha nor the beta and gamma component of collagen (lens nucleous and retina without pigmented epithelium).

[The course of zonular fibers in the area of pars plicata corporis cilaris pars plana, ora serrata and retina. Eectron microsocpic study].

The course of zonular fibers in the area of pars plicata corporis ciliaris could be shown down to the pigmented epithelial layer and its basement membrane. S ingle fibrils enter in a connection with the plasma membrane in allinvestigated parts. Fibrils could be observed in the cytoplasm of the ora serrata. For the other areas (pars plicata corporis ciliaris, parsplana) this can be suggested too.

Biochemical and electronmicroscopic investigations on Helix pomatia collagen.

The skin of Helix pomatia was investigated by biochemical methods and electronmicroscope. Biochemical investigations showed that Helix pomatia collagen represents a methionine-lacking collagen resistant to CNBr-cleavage. Electron microscopic studies showed a cross striation pattern of 53--57 nm.
