 Title    X-Ray Studies on Phospholipid Bilayers. V. Interactions with DDT  
 Abstract    The possible interaction of DDT with the lipids dimyristoyl lecithin (DML), dipalmitoylphos-phatidylethanolamine (DPPE) and tripalmitin (TP) was studied. The work was carried out on oriented films and crystalline powders of DDT-lipid mixtures at different molar ratios by X-ray diffraction techniques. The diagrams showed only the patterns of pure DDT and that of the corresponding lipid. It is concluded that new phases were not formed and, therefore, no interac­ tions occurred.

 Title    X-Ray Studies on Phospholipid Bilayers. VIII. Interactions with Chlorpromazine * HCl  
 Abstract    Chlorpromazine is a widely used phenothiazine tranquilizer known to alter the shape of normal erythrocytes and their osmotic fragility. In order to understand the nature of the interactions chlorpromazine • HCl (CPZ HCl) was made to interact with phospholipid bilayers formed by dimyristoylphosphatidylethanolamine (DMPE) and dimyristoylphosphatidylcholine (DMPC). This study was carried out by X-ray diffraction on crystalline powders of various molar mixtures of CPZ -HCl with DMPE and DMPC, with and without water. It was found that CPZ -HCl significa-tively affects the bilayer structure of DMPC in the presence of water, but not that of DMPE.

 Title    X-Ray Studies on Phospholipid Bilayers I. Polymorphic Forms of Dimyristoyl Lecithin  
 Abstract    A structural study o f the synthetic phospholipid, L-a-dimyristoyl lecithin (DM L), has been m ade by X-ray fiber diffraction methods. Three different types o f oriented specimens were prepared. They were X-ray photographed under the same conditions, including tem perature and relative humidity. T hree different types o f diffraction patterns, corresponding to different confor­ mations and/or packing arrangements, were found. They are characterized by their unit cell dimensions, space groups, molecular conformations, and packing arrangements.
