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 a/iy existing
mucin. The precipitate produced is filtered off, the filtrate treated with
2 per cent HC1 and wanned 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 fat 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 ligamenta 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. v. 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 Stollmann3
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.
