OVARIAL CYSTS. 627 



glycogen. In this last-mentioned case, first add acetic acid to the solu- 

 tion of the alcohol precipitate in water so as to precipitate any existing 

 mucin. The precipitate produced is filtered off, the filtrate treated with 

 2 per cent HC1 and warmed on the water-bath until the liquid is deep 

 brown in color. In the presence of pseudomucin this solution gives 

 TROMMER'S test. 



The other protein bodies which have been found in cystic fluids are 

 serglobulin and seralbumin, peptone (?), mucin, and mucin-peptone (?). 

 Fibrin occurs only in exceptional cases. The quantity of mineral bodies 

 on an average amounts to about 10 p. m. The amount of extractive 

 bodies (cholesterin and urea) and/ai is ordinarily 2-4 p. m. The remaining 

 solids, which constitute the chief mass, are protein bodies and pseudo- 

 mucin. 



The intraligamentary, papillary cysts contain a yellow, yellowish- 

 green, or brownish-green, liquid which contains either no pseudomucin 

 or very little. The specific gravity is generally rather high, 1.032-1.036, 

 with 90-100 p. m. solids. The principal constituents are the simple 

 proteins of blood-serum. 



The rare tubo-ovarial cysts contain as a rule a watery, serous fluid 

 containing no pseudomucin. 



The parovarial cysts or the CYSTS of the LIG AMENTA LATA may attain 

 a considerable size. In general, and when quite typical, the contents are 

 watery, mostly very pale-yellow-colored, water-clear or only slightly 

 opalescent liquids. The specific gravity is low, 1.002-1.009, and the 

 solids only amount to 10-20 p. m. Pseudomucin does not occur as a 

 typical constituent; protein is sometimes absent, and when it does occur 

 the quantity is very small. The principal part of the solids consists of 

 salts and extractive bodies. In exceptional cases the fluid may be rich 

 in protein and may show a higher specific gravity. 



In regard to the quantitive composition of the fluid from ovarial 

 cysts we refer the reader to the work of OERUM. 1 



E. LUDWIG and R. y. ZEYNEK have investigated the fat from dermoid cysts. 

 Besides a little arachidic acid, they found oleic, stearic, palmitic, and myristic 

 acids, cetyl alcohol, and a cholesterin-like substance. In regard to the occurrence 

 of cetyl alcohol see the work of AMESEDER, 2 page 239. 



The colloid from a uterine fibroma analyzed by STOLLMANN S contained a 

 pseudomucin soluble in water, and a colloid (paramucin) insoluble in water, both 

 of which behaved differently with alcohol as compared with the corresponding 

 substances from ovarial cysts.
