1.
1. Optcally-clear sols of ox-brain cerebral lipids prepared by ultrasonic irradiation (16–24 kcycles/sec) have been examined by physicochemical methods.
2.
2. The myelinic figures in the lecithin sols were broken down to disc-shaped micelles with a micellar weight of about 2·106.
3.
3. Sedimentation of dispersions of phosphatidylethanolamine and -serine and sphingomyelin indicated micellar weights similar to that for lecithin.
4.
4. The phospholipid sols, with the exception of phosphatidylethanolamine, were stable over several days and were not flocculated by dilute salt solutions.
5.
5. Sulphatides, unlike cerebrosides, were readily dispersed, due to the acidic groups on the molecules.
6.
6. No evidence for chemical changes resulting from ultrasonic irradiation was obtained from preliminary analyses.

1. The absorption of micellar solutions of conjugated bile salts and labeled fatty acids and/or monoglycerides have been demonstrated employing intestinal slices and brush border preparations.
2.
2. the absorption of the lipid from these solutions appears to be enzymical energetically independent and occurs from these solutions appears to be enzymically and energetically independent and occurs at a faster rate than corresponding solutions bound to albumin or in the emulsified state.
3.
3. The resynthesis of the abosorbed micellar lipids into triglycerides has been demonstrated and the relationship of these findings to the mechanism of the absorption of fats in vivo discussed.

A parallelism was found between hemolysis and erythrocyte phospholipid splitting induced by the action of cobra venom on washed erythrocytes of various species: guinea-pig, dog, human, rabbit. No significant phospholipid splitting was produced by cobra venom in camel and sheep erythrocytes, which are resistant to the hemolytic action of the venom. Isolated cobra venom phospholipase A (phosphatide acylhydrolase, EC 3.1.1.4) had no or slight hemolytic and phospholipid splitting action on the various erythrocytes, including those of the guinea-pig and dog, which are the most sensitive to the action of the whole venom. The different sensitivity of the various erythrocytes to the cobra venom is a reflection of their susceptibility to the action of venom direct lytic factor, a basic protein, which has hemolytic but no phospholipase activity. Isolated cobra venom phospholipase readily hydrolyzed the phospholipids of osmotic ghosts derived from both sensitive and resistant erythrocytes. Vipera palestinae venom which did not lyse the erythrocytes of any of the species tested, was also unable to hydrolyse the phospholipids in their osmotic ghosts. Cobra-venom direct lytic factor rendered the phospholipids of osmotic ghosts derived from sensitive erythrocytes available to the action of V. palestinae venom, but was not able to do so in the case of osmotic ghosts derived from resistant erythrocytes.
