In overdose, the antihistamines cause convulsions, hallucinations, excitement, ataxia, incoordination, and athetosis. On exam patients may exhibit fixed, dilated pupils with a flushed face, sinus tachycardia, urinary retention, dry mouth, and fever. At high doses the patient can become comatose, which is often followed by cardiorespiratory collapse and death within 2 to 18 hours (Babe and Serafin, 1996). Treatment of overdose is mainly supportive, with efforts to manage the anti-colinergic effects. 

CNS side effects include confusion, anxiety, lethargy, nausea and vomiting. GIT related effect is constipation. Other side effects are urinary retention, dry mouth, miosis, dysphoria, hypotension, skin rash, itching and urticaria. Tolerance, drug dependence and drug abuse are the main drawbacks of morphine.

Quinidine may be associated with a syndrome called cinchonism, which is characterized by headache, vertigo, and tinnitus. Procainamide may result in hypotension or a reversible syndrome similar to lupus erythematosus. Patients may develop positive antinuclear antibody (ANA) titers and complain of rash, arthralgia, and arthritis. Disopyramide is poorly tolerated due to its anticholinergic effects (urinary retention, dry mouth, blurred vision), and its use should be avoided in patients with congestive heart failure (CHF) due to negative inotropic effects.

Overdosage with trimipramine causes CNS stimulation followed by CNS depression. The first 12 hours after acute ingestion are a stimulatory phase characterized by excessive anticholinergic activity (agitation, irritation, confusion, hallucinations, parkinsonian symptoms, seizure, urinary retention, dry mucous membranes, pupillary dilatation, constipation, and ileus). This is followed by CNS depressant effects, including hypothermia, decreased or absent reflexes, sedation, hypotension, cyanosis, and cardiac irregularities (including tachycardia, conduction disturbances, and quinidine-like effects on the ECG).

Two elderly women developed agitation, confusion, urinary retention, dry mouth, and dilated pupils within 3 hours of taking the dried seeds of Datura stramonium. They recovered completely after symptomatic treatment for 5 days. 

Overdosage with atropine may cause palpitations and arrhythmias. Side effects of large doses of atropine include urinary urgency and retention, dry mouth, confusion, nausea, vomiting and dizziness. 

Solution Casting. The production of unsupported film and sheet by solution casting has generally passed from favor and is used only for special polymers not amenable to melt processes. The use of solvents was generally very hazardous because of their flammabiUty or toxic nature. The cost of recovery and disposal of solvents became prohibitive for many lower price film appHcations. The nature of the drying operations leads to problems with solvent migration and retention that are not problems with melt-processed polymers. 

CeUulose phosphate esters are also produced by treatment with sodium hexametaphosphate [14550-21-1] by the pad-dry-cure technique. These treated fabrics have high retention of breakiag and tearing strength (61). The reaction products contain more than 1.6% phosphoms and are iasoluble ia cupriethylenediamine [15243-01 -3] iadicating that some ceUulose cross-linking occurs. However, siace durable-press (DP) levels and wrinkle recovery values are low, it seems reasonable that only limited cross-linking takes place. 

Guar gum [9000-30-0] derived from the seed of a legume (11,16), is used as a flocculant in the filtration of mineral pulps leached with acid or cyanide for the recovery of uranium and gold (16). It is also used as a retention aid, usually in a chemically modified form (14,17). Starch and guar gum are subject to biological degradation in solution, so they are usually sold as dry powders that are dissolved immediately before use. Starch requires heating in most cases to be fully dissolved. 

Citric acid is used in carbonated beverages to provide tartness, modify and enhance flavors, and chelate trace metals. It is often added to jams and jellies to control pH and provide tartness. It is used in cured and freeze-dried meat products to protect the amino acids (qv) and improve water retention. Bakers use it to improve the flavor of fmit fillings in baked goods. Because citric acid is a good chelator for trace metals, it is used as an antioxidant synergist in fats and oils, and as a preservative in frozen fish and shellfish (7) (see Antioxidaisits). 

The enrichment program followed in the United States is (/) the enrichment of flour, bread, and degerminated and white rice using thiamin [59-43-8] C 2H y N O S, riboflavin [83-88-5] C2yH2QN4Na02P, niacin [59-67-6] CgH N02, and iron [7439-89-6]-, (2) the retention or restoration of thiamin, riboflavin, niacin, and iron in processed food cereals (J) the addition of vitamin D [67-97-0] to milk, fluid skimmed milk, and nonfat dry milk (4) the addition of vitamin A [68-26-8], C2qH2qO, to margarine, fluid skimmed milk, and nonfat dry milk (5) the addition of iodine [7553-56-2] to table salt and (6) the addition of fluoride [16984-48-8] to areas in which the water supply has a low fluoride content (74). 

The method used to apply and dry a fixative affects the degree of stiffness and hold it imparts to the hairstyle. If appHed and then manipulated with a comb, bmsh, or fingers as the polymer forms its film, the adhesive bonds between the hair are broken, the film coating the hair is broken, and the end result is a soft feel with Htde set retention. If the fixative is allowed to dry undisturbed, then the result is a firmer feel and better hold. 

Finishing sprays and spritzes are sprayed on clean, dry hair and tested for drying time, stiffness, combing ease, flaking after combing and stickiness upon contact with moisture. Additionally, hair hoi ding properties are evaluated by measurements of the cud retention at various humidities. Standardized water-set cuds are sprayed with standard amounts of product under controlled circumstances. They are then dried, placed into vadous humidity levels, and the cud fall monitored at vadous time pedods. 

In papemiaking, chemicals can be added either to the pulp slurry prior to sheet formation, ie, internal or wet-end addition, or to the resulting sheet after complete or partial drying, ie, surface or dry-end addition. The method chosen depends on retention and the desired effect. For example, strength additives usually are added internally if uniform strength throughout the sheet is wanted, but they are applied to the surface if the need is for increased surface strength. If an additive caimot be retained efftciendy from a dilute pulp slurry, then it is better to apply it to the surface of the sheet. 

Papermaking additives can be categorized either as process additives or as functional additives. Process additives are materials that improve the operation of the paper machine, such as retention and drainage aids, biocides, dispersants, and defoamers they are primarily added at the wet end of the paper machine. Functional additives are materials that enhance or alter specific properties of the paper product, such as fillers (qv), sizing agents, dyes, optical brighteners, and wet- and dry-strength additives they may be added internally or to the surface of the sheet.
