A Unified Approach to Analysis of Body Condition in Green Toads.

Body condition is increasingly used to assess the status of populations and as a proxy for individual fitness. A common, quick and non-invasive approach is to estimate condition from the relation between body length and mass. Among the methods developed for this purpose, the Scaled Mass Index (SMI) appears best suited for comparisons among populations.

[The nutritive value of carp (Cyprinus carpio)].

From January 1991 to February 1992 the composition of filleted carps was investigated. Special attention was given to a possible correlation to origin and season. The gutted, fresh fish were weighted and only the fillets were used for the investigation.

[The efficiency of photometric determination of skatole in slaughtered swine].

In a group of 264 boars, including both cryptorchides and hermaphrodites, skatole was measured using a photometric method developed in Denmark. It resulted in a concentration of skatole equivalents (SE) in the fat of 0.14 ppm in belly tissue and 0.

Prolonged radioprotective activity of WR-2721 linked to dextran.

The radioprotective agent WR-2721 was linked to dextran and poly(glutamic acid) respectively, to obtain a prolonged radioprotective ability. Male mice were administered these water soluble polymer conjugates one to 72 hours prior to a whole body irradiation with X-rays. A prolongation of radioprotective efficiency was achieved with two dextran-(WR-2721)-conjugates.

The influence of the solvent on the toxicity and radioprotective effect of thiophosphate WR2721 in mice.

The influence of various solvents on the toxicity as well as the protective efficiency of thiophosphate WR2721 in X-irradiated male mice is described. The use of Sörensen buffer as solvent with a pH-value of 7.4 leads to a statistically significant lower lethality in animals than aqua bidest.
