Management of carcinoma in situ of the vulva. | Concern about multicentricity and occult invasion has led authorities to recommend total vulvectomy in the management of carcinoma in situ of the vulva (VCIS). Of these considerations, only occult invasion has sufficient import to contraindicate a more conservative therapeutic approach. VCIS is being diagnosed with inc... | 851,134 | [

Depletion of docosahexaenoic acid in retinal lipids of rats fed a linolenic acid-deficient, linoleic acid-containing diet. | Rats were raised for 2 generations on a diet in which 1.25% methyl linoleate was the only source of fat. Control rats were given 1.0% methyl linoleate plus 0.25% methyl linolenate. Lipids were extracted from retinas and their fatty acids were analyzed by gas-liquid chromatography. Docosahexaenoic acid accounted for 33.... | 851,547 | [
