Rabbit.

Complete analyses of these stones have not been published. However, in view of the low cholesterol content reported in the stones, it is doubtful that these stones can be considered to be primarily cholesterol stones. The major constituents have not been identified, but rabbits form stones of various types readily, as shown by work on cholestanol-induced cholelithiasis and the early work on stasis and infection as etiological factors. 

005 to 5 mg kg sodium tungstate decreases the concentration of blood alkaline phosphatase.

This experiment describes the adaptation of the bicinchoninic acid (BCA) protein assay to a flow injection analysis. The assay is based on the reduction of Cu + to Cu+ by the protein, followed by the reaction of Cu+ with bicinchoninic acid to form a purple complex that absorbs at 562 nm. Directions are provided for the analysis of bovine serum albumin and rabbit immunoglobulin G, and suggestions are provided for additional analyses. 

Health and Safety Factors. The following toxicides for acetonitrile have been reported oral LD q (lats), 3030—6500 mg/kg skin LD q (rabbits), 3884—7850 mg/kg and inhalation LC q (i ts), 7500—17,000 ppm (29). Humans can detect the odor of acetonitrile at 40 ppm. Exposure for 4 h at up to 80 ppm has not produced adverse effects. However, exposure for 4 h at 160 ppm results in reddening of the face and some temporary bronchial tightness. 

Health and Safety Factors. The following toxicities have been reported for cyanoacetic acid oral LD q (rat) 1500 mg/kg subcutaneous LD q (rabbit), 1900 mg/kg and subcutaneous LD q (frog) 1300 mg/kg (29). Eor ethyl cyanoacetate the following toxicities have been reported interperitoneal LD q (mice), 750 mg/kg subcutaneous LD q (rabbits), 1500 mg/kg and subcutaneous LD q (frogs), 4000 mg/kg. 

Health and Safety Factors. See "General Health and Safety Eactors." The foUowing toxicides for 2-pentenenitrile have been reported dermal, LD q (rabbit) >200 mg/kg oral LD q (rat) 450 mg/kg 4-hr Inhalation LC q (rats) 740 ppm (29). 

Health and Safety Factors. Butyrolactone is neither a skin irritant nor a sensiti2er however, it is judged to be a severe eye irritant in white rabbits. The acute oral LD q is 1.5 ml,/kg for white rats or guinea pigs. Subacute oral feeding studies were carried out with rats and with dogs. At levels up... 

With respect to acute toxicity, based on lethaHty in rats or rabbits, acryhc monomers are slightly to moderately toxic. Mucous membranes of the eyes, nose, throat, and gastrointestinal tract are particularly sensitive to irritation. Acrylates can produce a range of eye and skin irritations from slight to corrosive depending on the monomer.

Fibers (see Fibers, survey) used in textile production can have a wide variety of origins plants, ie, ceUulosic fibers (see Fibers, cellulose esters) animals, ie, protein fibers (see Wool) and, in the twentieth century, synthetic polymers. Depending on the part of the plant, the ceUulosic fibers can be classified as seed fibers, eg, cotton (qv), kapok bast fibers, eg, linen from flax, hemp, jute and leaf fibers, eg, agave. Protein fibers include wool and hair fibers from a large variety of mammals, eg, sheep, goats, camels, rabbits, etc, and the cocoon material of insect larvae (sUk). Real sUk is derived from the cocoon of the silkworm, Bombjx mori and for a long time was only produced in China, from which it was traded widely as a highly valuable material.
