Abstract An improved method for the determination of vitamin B12, using a more sensitive mutant of Escherichia coli, which enables determination of 4-20 µµg./ml. of the vitamin, has been described. Comparative determinations of vitamin B12 content of human sera and of animal tissue extracts gave similar values when assayed with both E. coli and O. malhamensis. Although O. malhamensis is more specific in its response to cyanocobalamin than E. coli, the latter organism seems just as reliable for determination of vitamin B12 in serum and in tissue of human and animal origin. The simplicity, rapidity, and sensitivity of the improved E. coli assay make it very suitable for clinical use.

Abstract A method is described for confirming the identity of aflatoxins B1 and M1 in dairy products and liver extracts on a thin layer plate. Extracts and standards containing aflatoxins B1 and M1 are spotted on 10 × 10 cm plates, which are developed 2-dimensionally in mixtures of isopropanol-acetone-chloroform. After the first development, trifluoroacetic acidhexane (1 + 4) is sprayed on that part of the plate containing the separated extract components and the undeveloped standard spots of B1 and M1, and the plate is heated 6-8 min at 75°C. Then the plate is developed in a second direction, and the reaction products of B1 and M1 with trifluoroacetic acid from the extract are compared with the same derivatives of the respective standards. The method has been used successfully on extracts of milk, cheese, and liver containing 0.1 ng B1 or M1/g and can be completed in 35-45 min.

Abstract Electron capture gas chromatography is used to analyze milk and animal tissue extracts for the oxygen analog (diethyl O-3,5,6-trichloro-2-pyridyl phosphate) of Dursban®. Residues of 0.1 p pm were satisfactorily recovered from fat a n d muscle and 0.025 ppm from milk. Recoveries from brain, spleen, heart, kidney, and liver tissue averaged 62, 58, 24-40, 18, and 0%, respectively.

Proline Concentration

1. L-proline, by itself or in animal tissue extracts, inhibits the response of the sea anemone Anthopleura elegantissima to the alarm phermone, anthopeurine. 2. The effect of proline is mediated by a receptor that is specific for the structure and configuration of the part of the L-proline molecule containing the carboxyl and imino groups. 3. Proline inhibition is competitive, in the sense that the effects of a given proline concentration can be overridden by an increase in anthopeurine concentration. 4. The magnitude of proline inhibition increases with proline concentration and decreases as the duration of exposure to proline increases. 5. Neither the final conducting system mediating the alarm response nor the responding muscles are inhbited by proline. Inhibition presumably occurs at or soon after the level of anthopleurine receptors. 6. Proline inhibition may resolve the potential conflict between Anthopleura's mutually exclusive feeding and alarm pheromone responses.
