580 FIBROLYSIN MYKRH 



The B.P. volatile oil of mustard, distilled from black 

 mustard seeds after maceration with water, is antiseptic and 

 antipyretic, and one of the most poisonous of the volatile 

 oils. It is soluble in alcohol, and in fifty parts of water. 

 Rabbits are killed in two hours by a drachm, in fifteen 

 minutes by half an ounce, with symptoms of gastro-enteritis, 

 loss of sensation and muscular power, difficult breathing, 

 and collapse. Diluted and applied externally, it is a prompt 

 and powerful vesicant. 



PIBROLYSIN 



Fibrolysin (Merck) is described as composed of Thiosina- 

 mine (obtained from mustard oil) and salicylate of soda. 

 It occurs as a clear, colourless liquid, with a faint odour 

 and a slightly acrid taste. Fibrolysin has the reputation of 

 possessing the power to soften pathological fibrous tissue 

 and to prevent its contraction. Its use is indicated in 

 thickened and contracted tendons, indurations, fibrous 

 ankylosis, adhesions, corneal opacities, etc. No ill effects 

 have been noted from its administration ; and it is stated 

 to improve the appetite and general health. Rahne, 

 Kratzer, Train, and other veterinary surgeons, report 

 favourably of its use in ' induration of the thigh ' in a mare ; 

 'tendinitis fibrosa ' of both forelimbs with thickening and 

 shortening of the flexor tendons ; fibroid swelling of a 

 horse's hock, and enlarged fetlock joints. Fibrolysin may 

 be administered hypodermically, intravenously, or by intra- 

 muscular injection into the substance of the gluteal muscles. 

 The injections should be repeated daily, or at intervals of 

 two or three days, according to the case. Fibrolysin is 

 supplied in sterile glass ampullae, each containing 11*5 c.c., 

 in aqueous solution, or sufficient for one injection for the 

 horse.
