In an article entitled, “A Study of the Possible Role of Aluminum Compounds in Animal and Plant Physiology,” by McCollum, Rask, and Becker,’ these authors arrived at the conclusion that, “Aluminum is not a constituent of either plant or animal matter.” Since this conclusion is so contrary to what has been found by all previous investigators, we have performed the following experiments in order ...

OBJECTIVE To find out the effect of wheat grass on aluminum induced Alzheimer's disease in Wistar rats. METHODS Memory impairment was induced by aluminum chloride (4.2 mg/kg, i.p.) for 28 d. Memory function was assessed by Morris water maze test. To study the activity of wheat grass (100 mg/kg, p.o.), Wistar rats were administered it for 28 d along with aluminum chloride. Biochemical paramete...

The influence of aluminum on some serum parameters related to bone metabolism has been investigated by daily administration of aluminum over different periods of time. Daily administration of aluminum (1 mg/kg BW) for 20 or 50 days elevated serum phosphorous concentration by 16 percent and had no significant effect on serum calcium level. When aluminum was injected as a complex with citric...

Aluminum metal was found to liberate cesium almost quantitatively from pollucite ore when reacted under conditions of operation determined by experiments described in the paper. In the treatment, ore ground to pass a 150 mesh sieve is mixed with atomized aluminum and the mixture heated under an inert atmosphere in a retort. Pollucite ore from one source yielded its cesium when treated at 950°C ...

A study has been made of t he reactions of lithium aluminum hydride with methyl bromide, methylene chloride, meth ylene bromide, methylene iodide, chloroform, bromoform, and carbon t etrachloride. Except for hydrogen and unreacted h alida, essentia lly pure methane was formed in each case. The amount of hydrogen evolved increased with the n umber of halogen atoms in the molecule, reaching a max...

This introduction to the industrial primary aluminum production process presents a short description of the electrolytic reduction technology, the history of aluminum, and the importance of this metal and its production process to modern society. Aluminum's special qualities have enabled advances in technologies coupled with energy and cost savings. Aircraft capabilities have been greatly enhan...

Mice immunized with a subcutaneous protocol combining killed para­ sites and aluminum hydroxide gel exhibited significant resistance against subsequent challenge with Leishmania donovani promastigotes. Protec­ tion was greatest using 25 mg of aluminum hydroxide per injection. Resis­ tance elicited by this killed parasite and aluminum hydroxide protocol was as effective on day 14 as that provide...

Automobiles are required to be even lighter for further achieving environmental protection through fuel economy improvement, as well as safety feature enhancement and drivability improvement. Automotive suspensions are also required to reduce their weight and thus more aluminum is being adopted. Aluminum forgings, in particular, are often applied because of their significant weight reduction ef...

Chronic exposure to high concentrations of fumes during aluminum arc welding causes a severe pneumoconiosis characterized by diffuse pulmonary accumulation of aluminum metal and a corresponding reduction in lung function. Aluminum fume-induced pneumoconiosis is a rarely reported entity, of which the true incidence is unknown. We report the clinical, radiographic, microscopic, and microanalytic ...
