A simplijLed micromethod for the determination of curhonic unhydrose and its This inhibitors, T. H. Maren, J. Pharmucol. Exp. Therap., 130, 26-2~9 (1960). article describes a quantitative micromethod for determining carbonic anhydrase based on change of pH. Sensitivity of 0.05 ml. of mammalian blood diluted 1:lOOO. Progress in biochemical inuestzgations. I. Nitrogen compounds: 1959, S. Natelson, Microchem. J., 4, 321-42 (1960). A review to acquaint readers in general with the newer developments in microchemistry as applied to biological problems including instrumentation (202 references). Progress in biochemical investigations. II. Determination of elements in biological systems: 1959, A. L. Levy, Microchem. J., 4,343~52 (1960). A review covering developments in anaIytica1 and biological chemistry of metals and nonmetals with emphasis on micro aspects (81 references). Concerning the complexometric determination of potassium, M. Petar, Mikrochim. Actu, 1960,567-76. The method of Flaschka and Holasek for the determination in serum was investigated. Use of reflectance measurements in assessing the color chunges of ageing bloodsiuins D. Patterson, Nature, 187,688 (1960). Reflectance measurements are discussed. Analysis of unuesthetic mixtures by gas chromatography, E. R. Adlard and D. W. Hill, Nature, 186, 1045 (1960). An analysis of gas components in anaesthesia and in respiratory research is made.
Inorganic Microsynthesis IZeaction of diborune with uolutrle cyunides, H. J. Emeleus and K. Wade, J. Chem. Sot., 1960, 2614-17. The reaction of diborane with HCN, cyanogen, iodine cyanide, alkyl cyanides etc. on the 0.5 to 2 mmole (15-60 mg.) scale is described. The reaction of ammonia-trimethylboron with potassium in liquid ammoniu, and some properties of potassium amino trimethylborate, A. K. Holliday and N. R. Preparations using 0.5 to 1 mmole of Thompson, J. Chem. SW., 1960,2695-99. reagents are described. Isomerism und isomerisation of thio-bridged complexes of pltctinnm (II ), .f. Chatt and Some preparations of the decigram F. A. Hart, J. Chem. Sot., 1960, 2807-14. scaIe are reported on. The prepnration of some cobaltic porphyrin complexes, A. W. Johnson and I. ‘I’. Kay, J. Chem. Sot., 1960, 2979-83. The preparation of potassium [aetiochlorin I dicyanocobaltate ] from 11 mg. of cobaltous aetiochlorin I and potassium cyanide is described. (See specifically p. 2982.)
