testaden

(tes’tad-en) [L. tes’tis testicle + Gr. ἀδήν gland]. A therapeutic preparation of the testes of bulls: used in diseases of the nerves and spinal cord. Daily dose, go-120 gr. (6-8 gm.). 63 Of the crystal of pota ium dichromate: a green color will soon form. Wormley’s t. (for alkaloids): 1. Made by treating with an alcoholic solution of picric acid, when a yellow precipitate will be formed. 2. Made by treating with a solution of 1 part of iodin and 2 parts of pota ium iodid in 60 parts of water: a colored precipitate will be formed. Worm-Miiller’s t. (for glucose in the urine): A test made by boiling in a test-tube 4 c.c. of a 2.5 per cent. solution of copper sulphate and 2.5 c.c. of a solution of sodic pota ium,hydroxid. Boil each and mix, and a yellowish or ted precipitate will be formed. Wurster’s t.: 1. (For hydrogen dioxid.) Test paper is saturated with the solution of tetra methyl para phenyl end i am in: hydrogen dioxid turns it to a blue-violet color. 2. (For tyros in.) The suspected material is di olved in boiling water and a little quin on: a ruby-red color will form, changing slowly to brown. xanthin t. Same as Hoppe-Seyler’s t. xanthoprotein t. Same as Mulder's t. xylidin t. Same as Schiff's ¢. Yefimov’s t. ( for worms in urine): 1. From 5 to 10 c.c. of urine are treated with 5 or to drops of a solution of mercuric nitrate. If the precipitate formed is grayish or dirty, the patient has intestinal worms. 2. The crystals formed by evaporating a drop of urine are examined under the microscope. Granular crystals indicate the presence of cestodes; wax-like ones show the presence of nematodes. Yvon’s t.: 1. (For acetanilid in urine.) Extract it with chloroform and heat the residue with mercurous nitrate, when a green color will form. 2. (For alkaloids.) Add a solution of 3 gm. of bismuth sub nitrate, made by boiling in 40 c.c. of * water, to which are added 14 gm. of pota ium iodid and 40 drops of hydrochloric acid: a red color will show the presence of an alkaloid. Zaleski’s t. (for carbon monoxid in blood): To 2.c.c. of blood add an equal volume of water and 3 drops of a one-third saturated solution of copper sulphate: if carbon monoxid is present, a brick red deposit is thrown down; otherwise the precipitate is greenish brown. Zeisel’s t. (for colchicin): Di olve in hydrochloric acid, boil with ferric chlorid, and shake with chloroform: a brown or dark-red layer will form at the bottom. Zeller's t. (for melanin in urine): Add bromin water: a yellow precipitate will form, which changes slowly to black. Zenoni’s t.: Sputum is mixed with alcohol and stained with aqueous solution of safranin, when the mucin is colored yellow and the albumin red Zouchlos’ t. (for albumin in the urine): 1. Precipitate it with a mixture of 1 part of acetic acid and 6 parts of a 10 per cent. solution of mercuric chlorid. 2. Prepare a reagent with 100 parts of a 1o per Zwenger’s t. Same as Liebermann’s t.
