    Notizen: Summary Ca2+/calmodulin-dependent protein kinase II (CaM kinase II) is one of the predominant protein kinases in the brain. We found that CaM kinase II immunoreactivity was concentrated in the peripheral halos of Lewy bodies (LBs) in Parkinson's disease and Lewy body-like hyaline inclusions (LBHIs) in amyotrophic lateral sclerosis. An immunoelectron microscopic examination of LBs revealed that the filaments at the periphery of LBs were decorated with immunopositive deposits. Since CaM kinase II has a broad substrate specificity and can phosphorylate neurofilaments and other cytoskeletal proteins, it may play some role in the formation of LBs and LBHIs through the aberrant phosphorylation of the cytoskeletal elements in these inclusions.

    Notizen: Abstract Covalent immobilization of trypsin onto poly(2-hydroxyethyl methacrylate)/ polystyrene composite microspheres, produced by emulsifier-free seeded emulsion polymerization technique, was carried out using the cyanogen bromide method under various conditions. The highest enzymatic activities of the trypsin immobilized in this study against N-α-benzoyl-L-arginine ethyl ester and N-α-benzoyl-L-arginine-p-nitroanilide, as low-molecular substrates and casein as a high-molecular substrate, were high, as corresponding to 80%, 85% and 50% of those of free trypsin, respectively.
