    52 [vol. 6, THE DISTRIBUTION OF PHOSPHORUS IN COW'S MILK AND THE SCHEME FOR THE SEPARATION OF PHOSPHATIDES By Rinjiro SASAKI (From the Institute of Agricultural Chemistry, College of Agriculture, Tokyo Imperial University) (Received 9th September 1930) A. The Distribution of Phosphorus in Cow's milk In order to extract the phosphatides, it is necessary first to determine the distribution of phosphorus in cow's milk. Liquid milk can not be extracted with ether or with other organic solvents owing to its large content of water. The substance applied in this experiment is the milk powder, dried by the Buflovak drum drier below 70•Ž. Its content of moisture is 4.498%, deter mined by the method of drying in the air bath of 105•Ž. The content of total phosphorus was determined(5) in the ash of sample which was burned with a little of fusing mixture. In 100g. of milk powder In 100g. of dry matter Total phosphorus 0.745g. 0.781g. The amounts of phosphorus, which are soluble in the various organic sol vents, were determined by extracting with three solvents in the following orders. (A) Ether-Acetone-Alcohol (B) Acetone-Ether-Alcohol (C) Alcohol-Ether-Acetone Experiment (A) 1) At first a pair of each 10g. of sample was extracted with ether by the Soxhlet's apparatus for a week. After the extraction had been comp leted, the extract was freed from ether and weighed. In 100g.of milkpowder In 100g.of dry matter Total ether matters soluble 3.609g. 3.779g. 2) The above extract was dissolved in a very little of ether.

  • Particularly Hazardous Substances
    Particularly Hazardous Substances In its Laboratory Standard, OSHA requires the establishment of additional protections for persons working with "Particularly Hazardous Substances" (PHS). OSHA defines these materials as "select" carcinogens, reproductive toxins and acutely toxic materials. Should you wish to add: explosive, violently reactive, pyrophoric and water-reactve materials to this category, the information is included. Carbon nanotubes have also been added due to their suspected carcinogenic properties.

Abstract Background and objectives: Sargassum angustifolium is a brown alga in southwestern coastline of Persian Gulf. Regarding the presence of various bioactive compounds and evidence of antihypertensive effects in other species of Sargassum, we evaluated the effect of S. angustifolium ethanol extract in CdCl2-induced hypertension in Wistar rats. Methods: Alga extract was prepared by maceration method using 70% ethanol and assessed for total phenolics and salt content. CdCl2 (1.5 mg/kg/day) was administered intraperitoneally to the rats for two weeks. Treatment groups received S. angustifolium extract (20, 40 and 80 mg/kg) or nifedipine (10 mg/kg) orally and simultaneously were given CdCl2 for two weeks. Systolic blood pressure (SBP) and heart rate were measured using tail-cuff method. Total antioxidant capacity, urea, creatinine, electrolytes including sodium, potassium, calcium and chloride were estimated in blood samples. The weight and histopathology of kidney tissues were also evaluated. Results: The content of total phenolic as gallic acid equivalent and the salt as NaCl was 67.42 ± 9.5 mg/g and 6.9 g/100 g in dried ethanol extract, respectively.

    UNIVERSITY OF MISSOURI-KANSAS CITY CHEMICAL MANAGEMENT PLAN Revised May 2016 UMKC CHEMICAL MANAGEMENT PLAN This document constitutes the Chemical Management Plan (CMP) for the University of Missouri-Kansas City (UMKC). It was developed by the Environmental Health and Safety Department (EHS), to ensure the safe and proper use of hazardous and non- hazardous chemicals and to comply with applicable governmental regulations addressing the disposal of these chemicals. In addition, it was developed to foster waste minimization, and to provide the faculty and the staff with a management program to reduce the potential for accidents involving hazardous chemicals and/or wastes. Elements of the CMP include: a. a procedure for identifying potential or actual hazardous chemicals or wastes b. a procedure for periodic reexamination of those hazardous chemicals or wastes identified by the procedure in (a.) above as well as a systematic method for identification and evaluation of any new potential or actual hazardous chemicals or wastes c. procedures for labeling, and inventorying hazardous chemicals or wastes d. a procedure for identification and training of personnel directly responsible for ensuring that (a.), (b.), and (c.) are implemented e. a procedure for monitoring, recording, and reporting compliance with the CMP f. a procedure by which information generated by the CMP is provided to the persons performing waste analyses Each element is addressed as part of the complete CMP in the following paragraphs. 4 Table of Contents 1 Definitions 7 2 Identification

June, 1940 '"' ' - ' -1- Historical Any study of the stereochernistry of tricovalent atoms would necessarily involve members of the third and fifth periodic groups. Tertiary phosphines with heavy grol .pa would be most valuable for this work since phosphorus seems to be better suited to ezhi- bit asymmetry than any other element 01' the fifth group.<24) It is believed that the heavy groups would slow down the oscillations of the phosphorus atom and make possible the resolution of the optical isomers .. However, this work has been retarded by the lack of a convenient means of preparing asymmetrical sub- stituted triaryl phosphines. The usual method of preparing triaryl phosphines is by the reaction of the appropriate phosphenyl chloride with a Grignard reagent.
