Organophosphorous (OP) chemical warfare nerve agents mainly sarin and tabun were used during the Iran-Iraq war with high mortalities. In addition to atropine and oximes, the followings have recently been used successfully for the treatment of OP poisoning. 1. Sodium Bicarbonate: Infusion of high doses of sodium bicarbonate (5 mEq/kg in 60 min. followed by 5-6 mEq/kg/day to obtain arterial blood...

Metallic magnesium and compounds such as magnesium hydroxide Mg(OH)2 have been shown to have osteoconductive properties under experimental conditions and are gaining an increasing interest in the field of degradable biomaterials. The application of the compounds as implant coatings could support implant incorporation, resulting in an increased period of use of the implants. A variety of Mg-cont...
Granick (1948, 1950, 1961) has isolated different mutants of Chlorella which are unable to synthesize chorophyll and which accumulate magnesium protoporphyrin, magnesium vinyl phaeoporphyrin a5 and a monoester of magnesium protoporphyrin, presumed to be the monomethyl ester. Granick (1961) has proposed that these compounds are intermediates in chlorophyll biosynthesis, and it has been suggested...
Calcium and magnesium are essential for survival but it is unknown how animals detect and consume enough of these minerals to meet their needs. To investigate this, we exploited the PWK/PhJ (PWK) strain of mice, which, in contrast to the C57BL/6J (B6) and other inbred strains, displays strong preferences for calcium solutions. We found that the PWK strain also has strong preferences for MgCl2 a...

A new ketone Isonitroso phenyl 2 propanone (HINP2P) has been synthesized by the reaction of Benzyl magnesium chloride with cadmium chloride and acetyl chloride. On subsequent treatment of Phenyl 2 propanone with namyl nitrite gives Isonitroso Phenyl 2 Propanone. The structure of these compounds has been confirmed by physiochemical and spectral data. A preliminary screening of these compounds fo...
I n t r o d u c t o r y . T h e narcotic effect as well as the toxicity of magnesium salts, when introduced subcutaneously, depend to a great degree upon the readiness with which they are eliminated from the body. By what path are these salts eliminated? Are they excreted by the intestinal canal or are they eliminated through the kidneys? Meltzer and Auer" state that from their experiments they...
Titanium and its alloys are widely used in modern supersonic aircraft rockets, submarines ships, the chemical food industries, as well other areas of technology. In process obtaining titanium from ore, workers may be exposed to metal dust (Ti) dioxide (TiO2), highly toxic compounds – gaseous tetrachloride (TiC14), hydrolysis products, chlorine phosgene vapors. The study influence produc-tion co...
Background: The development of several disorders, such as cardiovascular diseases, diabetes and osteoporosis, has been linked to suboptimal dietary magnesium (Mg) intake. In this context, a number of studies have tried to investigate which Mg compounds are best suited for Mg supplementation. Results suggest that organic Mg compounds are superior to the inorganic Mg oxide in terms of bioavailabi...
