Sahcyhc acid USP, EP, and other pharmacopeia grades are used medically as antiseptic, disinfectant, antifungal, and keratolytic agents. Sahcyhc acid is formulated in lotion or ointment formulations for the treatment of dandmff, eczema, psoriasis, and various parasitic skin diseases. Because the keratolytic property of this aromatic acid has use in the safe removal of dead skin cells from the surface of healthy skin, the acid is used in concentrated sahcyhc acid solutions or suspensions to remove warts and corns. In more dilute form, sahcyhc acid preparations have found use in dandmff and eczema treatment. Sahcyhc acid has been considered and found effective by the Advisory Committees to the FDA in various over-the-counter (OTC) dmg regulated uses. Among these are acne products, dermatitis, dry skin, dandmff and psoriasis products, and foot care products (24). 

Uses are estimated to be manufacture of hydrosulfites and other chemicals, 40% pulp and paper, 23% food and agriculture (mainly corn processing), 14% water and waste treatment, 9% metal and ore refining, 6% oil recovery and refining, 4% and miscellaneous, including sulfonation of oils and as a reducing agent or antioxidant, 4% (270,271). 

In this period, the empirical healing of certain diseases by foods was estabUshed. Examples (3) were the treatment of night blindness (vitamin A deficiency) with hver ia many cultures over centuries, of beriberi (vitamin deficiency) by use of unpoHshed rice by the Japanese navy, of scurvy (vitamin C deficiency) by citms fmits ia the British navy or piae needle extracts by North American natives, and pellagra (niacia deficiency) by a dietary shift away from corn-based foods ia many countries. Other, nondietary empirical treatments iavolved, eg, exposure of children ia northern latitudes to sunlight to cute tickets (vitamin D deficiency) (4). 

Ionics Incorporated (Watertown, Massachusetts), the leading ED suppHer, has sold more than 2000 ED and EDR plants having a combined capacity of probably more than 600,000 mr / d. These were originally furnished with probably more than 1.2 x 10 of membrane. More than 2000 other ED and EDR plants have been built and installed in China. These plants have a combined capacity of more than 600,000 mr / d and were originally furnished with probably more than 1.2 x 10 of membrane. Also it is estimated that more than 1000 ED and EDR plants have been built and installed in the CIS. These plants have a combined capacity of probably more than 300,000 m /d, probably originally furnished with more than 600,000 m of membrane. Roughly 100 plants have been installed by other companies such as Corning Erance (formerly S.R.T.I.) and Portals Water Treatment Ltd. (formerly Permutit-Boby). 

Also, pilot plant and laboratory scale anaerobic studies have demonstrated successful treatment of wastewaters of 5,000 to 50,000 mg/L GOD from corn chips containing soluble and colloidal corn starch and protein, cheese whey, organic chemicals, food, bakeiy, breweiy, paper mill foul condensate, paint, and numerous other hazardous anci non-hazardous materials. 

It has also been found by Sair and Fetzer 28) that extraction of certain solubles from corn by treatment with alcohol materially hastens the speed of drying in a vacuum oven. 

Workers are normally chosen for their skills and experience in carrying out the required tasks for the field portion of the study. For example, if one were doing research on exposure of custom applicators during treatment of corn in the Midwest USA, the researcher would probably contact an agricultural extension agent in the part... 

No deleterious effects of either the wheat mulch or tillage were observed on soybeans (Table V) or corn (data not presented). In general, crop growth was better in mulched or no-till plots. Enhanced soil moisture in the mulched treatments and reduced morningglory densities in the non-tilled treatments may have contributed to improved crop growth. 

Study 2. The effects of wheat, oats, barley and rye mulches on three broadleaf weed species and crabgrass (Digitaria spp.) are shown in Table VI. Weed control data for the corn test at Kinston are not presented because of poor cover crop kill by the paraquat treatment.

Relatively pure xylan isolated from the holocellulose of aspen (Populus) wood is said to contain 85% of xylose residues.78 One of the characteristic properties of xylan is its ease of hydrolysis. Because it hydrolyzes much more readily than cellulose, mild acid treatment may be employed to bring about preferential hydrolysis of xylan from plant material. Xylose is ordinarily prepared in the laboratory by direct sulfuric acid hydrolysis of the native xylan in ground corn cobs.74 Hydrolysis in hydrochloric acid proceeds rapidly, but decomposition to furfural also occurs to some extent.76 A commercial method for the production of D-xylose from cottonseed hulls76 and straw77 and from corn cobs17 78 has been described. 

Dermal exposure of mice to 3.6 mg/kg of mirex, three times/week for 4 weeks, resulted in mild epidermal proliferation (Moser et al. 1992). Application of an unspecified amount of mirex to the skin of rabbits for 6-7 hours/day, 5 days/week for 9 weeks, resulted in slight erythema and scaling after day 5 (Larson et al. 1979a). This effect was reported to be reversible after 2 days without treatment. No signs of dermal irritation were observed in rabbits exposed to varying amounts of a 20% solution of chlordecone in corn oil (Larson et al. 1979b). 

Corn seed treatment has not usually resulted in improvement in stand where it has been tried in Mexico. High soil temperatures, favoring rapid emergence, tend to reduce any possible benefit. One important need is a good repellent that can be safely applied to corn seed. Rodents and crows are common thieves in recently planted fields, and are responsible for much of the replanting that has become customary in tropical lands.
