This review article describes a potential usefulness of transgenic and knock-out mice for biological safety research with respect to each toxicological category for safety evaluations, such as studies for carcinogenicity, general toxicology, genotoxicologic testing, and immuno-toxicological evaluations. In the carcinogenicity, a possible model required for a short-term study in carcinogenicity was discussed. Further, a couple of future subjects were focused specifically on the biotechnology-derived pharmaceuticals and the biotechnical recombinant-mice as a second generation, i.e. experimental mice with double or multiple gene-recombination. Those usefulnesses were also introduced briefly. Establishing the biotechnical recombinant-mice for each safety testing contributes not only to simplify and qualify the on-going evaluation system, but also to the traditional animal studies to be re-evaluated, so that the solutions may lead them to a future in vitro-alternative system much smoothly. For general references, historical reviews on the biotechnical recombination in experimental animals were also briefly introduced to elucidate a new broad area in developmental biology.</p>","PeriodicalId":11656,"journal":{"name":"Eisei Shikenjo hokoku.

In this assay hydroxylated mono- and dianthraquinone glucosides are chelated with boric acid, and the fluorescence intensity of the chelate is determined against that of the Reference Standard (RS). In the establishment of this RS, sennosides content in the candidate material must be determined accurately by fluorophotometry. The Sennoside AB for assay, prepared as an equimolar mixture of the purified sennoside A and Sennoside B, was used as the RS for the fluorophotometry. Based on the above concept, sennosides content in the candidate was determined as calcium salts to be 60.1 +/- 1.6% by the fluorophotometry. Thus the sennosides content of this Sennosides RS was certified to be 60%. Separately, contents of Sennoside A (SA) and Sennoside B (SB) in this candidate were determined by using HPLC. As a result, the sum of SA and SB was estimated to be 38% as free acids. Thus it was suggested that about 20% of dianthraquinone glucosides other than SA and SB and anthraquinone glucosides may be included in this Sennoside RS as free acids. Analytical results on the USP Sennosides RS were also shown and discussed, compared with the present Sennosides RS.</p>","PeriodicalId":11656,"journal":{"name":"Eisei Shikenjo hokoku.
