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. -
Phosphorus Oxychloride CAS No
Product Safety Summary Phosphorus Oxychloride CAS No. 10025-87-3 This Product Safety Summary is intended to provide a general overview of the chemical substance. The information in the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found in the Safety Data Sheet (SDS) for the chemical substance. Names Phosphorus oxychloride Phosphorus trichloride oxide Phosphoric trichloride POCl 3 Product Overview Solvay Novecare does not sell phosphorus oxychloride directly to consumers. Phosphorus oxychloride (POCl3) is used as a chemical intermediate to produce a variety of products which are used in several applications including manufacture of triarylphosphate esters which are used as flame retardants as well as an intermediate in the production of pharmaceutical, textile and agricultural chemicals. Phosphorus oxychloride is used in industrial applications and other processes where workplace exposures can occur. Consumer exposure does not occur as phosphorus oxychloride is not used in any commercially available product. Phosphorus oxychloride is dangerous to human health. Phosphorus oxychloride may be fatal if inhaled, highly toxic if swallowed, harmful if absorbed through skin and can cause severe burns which may result in scarring. Phosphorus oxychloride is consumed in manufacturing processes. POCl3 can make its way into the environment through unintentional releases (spills). POCl3 will not bioaccumulate but is not biodegradable. POCl3 in higher concentrations can be harmful to aquatic life due to formation of acids from the hydrolysis of POCl3. When released into the atmosphere, phosphorus oxychloride exists as vapor. -

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. This table is designed to assist the laboratory in the identification of PHS, although it is not definitively conclusive or entirely comprehensive. *Notes on the proper use of this table appear on page 12. 1 6 5 2 3 4 Substance CAS National Toxicity National Program Carcinogen Toxin Acute Regulated OSHA Carcinogen Group IARC Carcinogen Toxin Reproductive Violently Reactive/ Explosive/Peroxide Forming/Pyrophoric A-a-C(2-Amino-9H-pyrido[2,3,b]indole) 2648-68-5 2B Acetal 105-57-7 yes Acetaldehyde 75-07-0 NTP AT 2B Acrolein (2-Propenal) 107-02-8 AT Acetamide 126850-14-4 2B 2-Acetylaminofluorene 53-96-3 NTP ORC Acrylamide 79-06-6 NTP 2B Acrylyl Chloride 814-68-6 AT Acrylonitrile 107-13-1 NTP ORC 2B Adriamycin 23214-92-8 NTP 2A Aflatoxins 1402-68-2 NTP 1 Allylamine 107-11-9 AT Alkylaluminums varies AT Allyl Chloride 107-05-1 AT ortho-Aminoazotoluene 97-56-3 NTP 2B para-aminoazobenzene 60-09-3 2B 4-Aminobiphenyl 92-67-1 NTP ORC 1 1-Amino-2-Methylanthraquinone 82-28-0 NTP (2-Amino-6-methyldipyrido[1,2-a:3’,2’-d]imidazole) 67730-11-4 2B -
The Effect of Sargassum Angustifolium Ethanol Extract on Cadmium Chloride-Induced Hypertension in Rat

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. -
