Histochemical Studies of Lipids in the Ovaries of Domestic Animals

Abstract

The results obtained in this investigation are summarized as follows.
1. The lipids are found abundantly in the ova of sows and dogs, moderately in those of cows, sheep and goats, and slightly in those of rabbits, rats, mice and hamsters.
2. These lipids are mainly composed of phospholipids and neutral fats; these are abundant in the ova of sows and dogs, and a little less in those of cows, sheep and goats. No cerebrosides, fatty acids, cholesterols are found in the ova of the animals used. The ketosteroids are found slightly in the ova of sows and dogs, but not in those of others.
3. In the corpora lutea and interstitial glands are found the phospholipids, neutral fats, fatty acids, cholesterols and ketosteroids.
