SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Interactions · 5 items

In a case study of patients on long-term dialysis, systemic aluminum absorption with concurrent oral citrate (as an alkalinizing agent) and aluminum containing phosphate binder (eg, aluminum hydroxide or carbonate) was significantly increased. Based on the proposed mechanism and pharmacologic similarity, an interaction may be expected to occur between citric acid and other aluminum salts (eg, aluminum phosphate, aluminum glycinate, attapulgite, dihydroxyaluminum, kaolin, magaldrate). It has been shown that following concurrent administration of citric acid (from lemon juice) and aluminum hydroxide there is an increase in serum levels of a nonionized aluminum citrate complex, which is postulated to easily pass the gastrointestinal barrier. Simultaneous administration of citric acid and aluminum hydroxide should be avoided since significant systemic absorption of aluminum may occur. This may be of additional concern in patients on long-term dialysis or with impaired renal function. /Aluminum salts/

... 25 Dialysis patients that experienced accidental exposure to aluminum and parathyroid hormone were examined. At the same time as parathyroid hormone decreased, serum calcium increased. Based on this observation it has been suggested that aluminum is incorporated, instead of calcium, into the bone and that this leads to the osteomalacia characteristic of aluminum-induced bone disease. Instead of being incorporated into osteoid bone tissue, calcium returns to the circulation which in turn inhibits the parathyroid hormone release from the parathyroid. In support of this hypothesis, ... a strong correlation between bone aluminum content and the amount of bone occupied by unmineralized osteoid in humans was found. Experimental support for the hypothesis of calcium aluminum interactions has also been provided in studies on chicks. /Aluminum/

Groups of 120 Atlantic salmon fry (Salmo salar, 1 g mass) were kept in through flow tanks of water (pH 5) containing various concn of aluminum and silicic acid. The aluminum concn in all but the control tank (0.85 umol aluminum/l) were 6-7 umol/l, at acutely toxic levels. Silicon levels were 0.66 umol/l (control), 93.06, 24.89, 5.46, and 0.60 umol/l, corresponding to silicon:aluminum ratios of 13.0, 3.7, 0.9, and 0.1. Exchangeable aluminum, ie, aluminum retained on Amberlite, was 6.00, 5.00, 4.11, and 1.52 umol/l in test tanks, respectively. Fish were exposed for 96 hr, and the proportion of dead fish was recorded at 12-hr intervals. The whole experiment was run three times; data are from all runs combined. At a silicon:aluminum ratio of 13, acute toxicity of aluminum was eliminated and gill structures of the fish were normal. Percent survival versus time was higher for the higher silicon:aluminum ratio groups. Accumulation of aluminum by fish fell sharply as the exchangeable aluminum increased. aluminum and silicon levels in fish were 0.44 and 0.01 (control), 0.40 and 0.54 (silicon:aluminum ratio of 13), 2.04 and 0.35 (slicon:aluminum ratio of 3.7), 2.49 and 0.33 (silicon: aluminum ratio of 0.9), 2.38 and 0.08 (silicon:aluminum ratio of 0.1) umol per g dry mass, respectively. /Aluminum/

To elucidate the interaction between aluminum and certain essential trace metals, an experiment was performed on rats fed diets with suboptimal or optimal levels of zinc or copper. Half of each group of animals were fed the same diet but with 1000 ppm aluminum added. Changes were noted after 120 days. Severe testicular damage was seen in rats fed either the low zinc or the low copper diet. The lesions included a wide range of spermatogenic cell degeneration and tubular atropy. When aluminum was added to the diet, the testicular destruction of zinc deficient rats was significantly reduced. This indicated that the presence of aluminum in the diet projected the testis against the damage cauesd by zinc deficiency. Pituitary glands were examined. Hypertrophy of basophiles was more pronounced in rats fed the suboptimal zinc or copper diet. When aluminum was added to their diet, the changes were reversed. The mechanims by which aluminum protects male gonadal functions against zinc deficiency are discussed. This study is the first to demonstrate the preventivve effect of aluminum against testicular damage caused by zinc deficiency. /Aluminum/

Health Effects · 1 item

Aluminum targets the nervous system and causes decreased nervous system performance and is associated with altered function of the blood-brain barrier. The accumulation of aluminum in the body may cause bone or brain diseases. High levels of aluminum have been linked to Alzheimer's disease. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium.

Environmental Fate · 4 items

AQUATIC FATE: The adsorption of aluminum by fine particulates was studied in Whitray Beck, a hill stream in England. ... Uptake of aluminum by the particles increased with total aluminum, with pH, and with particle concentration, although the fraction of aluminum bound at a given pH and particle concentration decreased with total aluminum ... . /Aluminum/

TERRESTRIAL FATE: Air dried, <2 mm fractions of 3 soil samples from The Netherlands and 1 from New Hampshire, were taken from the surface and subsurface horizons of two podzols (Haplorthods) and of a recent driftsand (Udipsamment). Duplicate samples of each emulsion soil horizon were leached ... with aqueous hydrogen chloride (pH 3.0). ... Charge balances of the leachates indicate that dissolved aluminum is present mainly as aquo-aluminum (+3). Only in leachates of podzol Bhs horizons is a significant fraction (20-30%) of dissolved aluminum organically complexed. Dissolved aluminum concn are significantly correlated with the organic (tetrasodium pyrophosphate extractable) aluminum content of the soil sample. Mobility of aluminum in the Hubbard Brook soils is significantly lower than in the Dutch soils, because of higher soil-solution pH values. /Aluminum cmpd/

TERRESTRIAL FATE: Albic and spodic soil horizons were sampled from old growth eastern white pine/mixed northern hardwoods. Adirondacks, and an ochric soil horizon was sampled from the Appalachian plateau of NY State. 21 Three horizon forest floor and 21 forest floor/mineral soil (field moist equivalent of 12.0 oven dry albic, spodic, or ochric mineral soil) columns were leached in triplicate with either 10 uM nitric acid (pH 5), 5 uM sulfuric acid (pH 5), 100 uM nitric acid (pH 4), 50 uM sulfuric acid (pH 4), 1000 uM nitric acid (pH 3), 500 uM sulfuric acid (pH 3), or distilled, deionized water (pH 5.7) control treatment). Nitric acid leached more aluminum than did sulfuric acid from forest floor/spodic soil columns. Increasing the nitric acid concn from pH 3-5 increased total aluminum concn in leachates from 0.70 to 0.85 mM, while increasing sulfuric acid had no effect. Addition of pH 3 sulfuric acid to forest floor/spodic columns raised leachate pH relative to pH 3 nitric acid and controls, and resulted in the lowest aluminum concn of all treatments in the first 3 of 4 sequential leachings. /Aluminum/

Albic and spodic soil horizons were sampled from old growth eastern white pine/mixed northern hardwoods sites in the Adirondacks, and an ochric soil horizon was sampled from the Appalachian Plateau of NY State. 9 Three horizon forest floor, 9 mineral soil (field moist equivalent of 12.0 oven dry albic, spodic, or ochric mineral soil) and 9 forest floor/mineral soil columns were leached with 60 ml of (a) 10 mM ammonium nitrate (control), (b) 1.0 mM nitric acid in 10 mM ammonium nitrate (pH 3), and (c) 1.0 mM ammonium nitrate (pH 3) at the rate of 10 ml/hr. The above procedure was repeated on each mineral soil without a forest floor, except leaching soln were 0.5 mM calcium nitrate or calcium sulfate, each in 10 mM ammonium nitrate. Adding 2 and 0.5 cmol sub c (H+)/kg to forest floor and minera soils, respectively, simulated snowmelt additions. Total aluminum concn in leachates from forest floor/albic or forest floor/ochric columns were greater than the sum of concn in leachates from the forest floor and mineral horizon when leached separately. This positive synergistic behavior of the forest floor-mineral horizon sequences was also observed in the forest floor-spodic horizon sequence when leached with control soln, but the synergism was negative for both labile and non-labile aluminum when leached with the acids. Sulfuric acid leached less aluminum from the spodic horizon than did nitric acid, regardless of the presence of a forest floor, but nitric acid, sulfuric acid, and control soln leached similar concn of aluminum from the albic and ochric horizons. The forest floor effects on the mineral soil leachates were attributed to effects of calcium, sulfate, nitrate, and dissolved organic carbon leached from the forest floor to the mineral horizon since forest floor removed nearly all added H+. /Aluminum/

Pharmacodynamics · 1 item

The presence of potassium alum reduces swollen mucous membranes that result from inflammation of the nasal, gastrointestinal and urinary passages as well as in the presence of excessive secretions. The induction of the coagulation cascade will also stop bleeding.

Mechanism of Action · 4 items

The main functions of potassium alum in drugs are as an astringent, antiseptic or adjuvant agent. The astringent action is performed by the induction of coagulation in the superficial tissue layers until the formation of a crust. The formation of alum ions neutralize the charges on plasma proteins, causing the blood to coagulate. Similar effect is observed in disinfectants where these ions react with the free organic acid and thiol groups of proteins on microbes and free proteins, resulting in protein precipitation. This action will generate the contraction of the tissue and dry up secretions. Its adjuvant properties are mainly used in the production of vaccines where the presence of this chemical enhances the immune response.

Excessive dietary aluminum has been proposed to be a factor contributing to several neurological disorders in humans. Six 8 week old female Swiss Webster mice were fed for 10 weeks purified diets containing 100 (control, 100 aluminum, 500 (500 aluminum) or 1000 (1000 aluminum) ug aluminum/g diet. Brain and liver lipid peroxidation was determined by evaluating the production of 2-thiobarbituric acid reactive substances in brain and liver homogenates in the presence or absence of 50 mM ferrous iron. 2-Thiobarbituric acid reactive substances production in the absence of iron in brain homogenates from mice fed the 1000 aluminum diet was higher (30%) than that in the 100 aluminum control group (3.1 versus 2.4 nmol 2-thiobarbituric acid reactive substances/mg protein). The additional of ferrous iron increased 2-thiobarbituric acid reactive substances production in-brain homogenates from all 3 dietary group. The iron induced 2-thiobarbituric acid reactive substances production was 26% higher in the 1000 aluminum brain homogenates than in the 100 aluminum group (4.9 vs. 3.9 nmol 2-thiobarbituric acid reactive subtances/mg protein). Brain 2-Thiobarbituric acid reactive substances production in the presence and absence of iron was similar between the 100 and 500 aluminum groups. 2-Thiobarbituric acid reactive substances production in liver homogenates measured either with or without iron was similar for the 3 groups. These results show that, in mice, dietary aluminum intoxication leads to increased brain 2-thiobarbituric acid reactive substance production, suggesting that enhanced lipid peroxidation may be one possible mechanism underlying the neurological damage associated with increased tissue aluminum. /Aluminum/

Evidence is presented indicating that dementias are associated with a relative insufficiency of magnesium in the brain. Such insufficiency may be attributable to low intake or retention of magnesium; high intake of a neurotoxic metal, such a aluminum, which inhibits activity of magnesium requiring enzymes; or impaired transport of magnesium and/or enhanced transport of the neurotoxic metal into brain tissue. It is proposed that Alzheimer's disease involves a defective transport process, characterized by both an abnormally high incorporation of aluminum and an abnormally low incorporation that an altered serum protein contributes to the progression of Alzheimer's disease by having a greater affinity for aluminum than for magnesium, in contrast to the normal protein, which binds magnesium better than aluminum. The altered protein crosses the blood-brain barrier more efficiently than the normal protein and competes with the normal protein in binding to brain neurons. Binding of the altered protein to the target neurons would both facilitate aluminum uptake and impede magnesium uptake. Evidence suggests that albumin is the serum protein that is altered. /Aluminum/

Aluminum is established as a neurotoxin, although the basis for its toxicity is unknown. It recently has been shown to alter the function of the blood-brain barrier, which regulates exchanges between the central nervous system and peripheral circulation. The blood-brain barrier owes its unique properties to the integrity of cell membranes that comprise it. Aluminum affects some of the membrane like functions of the blood-brain barrier. It increases the rate of transmembrane diffusion and selectively changes saturable transport systems without disrupting the integrity of the membranes or altering CNS hemodynamics. Such alterations in the access to the brain of nutrients, hormones, toxins, and drugs could be the basis of CNS dysfunction. Aluminum is capable of altering membrane function at the blood-brain barrier; many of its effects on the CNS a well a peripheral tissues can be explained by its actions as a membrane toxin. /Aluminum/

Metabolism/Metabolites · 2 items

Potassium alum does not go through a metabolic pathway. When ingested or absorbed, it will get rapidly dissolved and it will form ions that will later generate other salt derivatives.

Aluminum is poorly absorbed following either oral or inhalation exposure and is essentially not absorbed dermally. The bioavailability of aluminum is strongly influenced by the aluminum compound and the presence of dietary constituents which can complex with aluminum and enhance or inhibit its absorption. Aluminum binds to various ligands in the blood and distributes to every organ, with highest concentrations found in bone and lung tissues. In living organisms, aluminum is believed to exist in four different forms: as free ions, as low-molecular-weight complexes, as physically bound macromolecular complexes, and as covalently bound macromolecular complexes. Absorbed aluminum is excreted principally in the urine and, to a lesser extent, in the bile, while unabsorbed aluminum is excreted in the faeces. (L739)

MeSH Pharmacological Classification · 1 item

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund&apos;s adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
