The new therapy procedures for viper attack.

In Slovak Republic and the region of Central and Eastern Europe the viper is the only species of venomous snake living in wild. During the last nine observed years (1993-2002) the Toxicological Information Center (TIC) was consulted in 81 cases of individuals attacked by snakes. 51 of these cases were by viper, rattlesnake 6, and green mamba once. 23 cases were by non-venomous snakes; adder 22 times and royal snake once. The viper and adder attacks occurred in the wild and the other cases with snake keepers. None of affected individuals died. Our contribution contains the new recommended therapy procedures for viper attack.

[Detection of secretion of beta-galactosidase by plant cells].

A simple, sensitive and reproducible method of detection of extracellular beta-galactosidase was worked out. beta-Galactosidase secreted by the callus culture, or the roots of sprouting plants, hydrolyzes the substrate (6-bromo-2-naphthyl-beta-D-galactopyranoside) to produce beta-D-galactose and 6-bromo-2-naphthol, which after simultaneous azocoupling with hexazotized p-rosaniline, or basic fuchsine, produce a reddish brown compound, nearly insoluble in water (a diazonium salt). The colouring under the callus culture and around it, as well as the colouring of the roots of the sprouting plants, is a manifestation of the activity of extracellular beta-galactosidase by the objects under study. The intensity of the colouring is a measure of their enzymatic activity. The share of intracellularly localized enzyme represents the majority and the share of extracellular beta-galactosidase the minority.
