The Biological Activity of Retinotaurine
The Journal of Nutrition, 1982The ability of the biliary metabolite retinotaurine to reverse the cornification of vaginal epithelial cells induced by vitamin A deficiency was assessed using a vaginal smear assay. Retinotaurine activity was examined following the intravaginal administration of 10(-12) mol to 10(-8) mol of this compound per vagina.

Biological activity of sterigmatocystin
Mycopathologia et Mycologia Applicata, 1968The biological activity of sterigmatocystin towards mice, ducklings, and some microorganisms was determined. The LD50 of sterigmatocystin for mice was in excess of 800 mg/kg. Aflatoxin B1 was 125 times more toxic in the ducklings tests than was sterigmatocystin.

1996
The addition of organic manure not only maintains but even improves soil fertility and, from earliest times, humus has been recognized as one of the major natural resources for agricultural purpose. In the absence of animal dung the value of green manure was recognized by the ancient Chinese (Jiao, 1983), while the Romans systematically used animal ...

Biological Activity of Phosphoramidothionates
Nature, 1966IN the course of our work on this class of compound an animal-anthelmintic1 and a selective herbicide2 had previously been discovered. Common to the structures of the two compounds was the linking of the phosphor-amidothionate group (I) to a chlorinated phenyl ring by an oxygen atom.
