Abstract: Novel liposome-entrapped cationic, lipophilic drug compositions, e.g., anthracycline antineoplastic agent compositions, and multistep entrapment/loading procedures for preparing them are disclosed. These procedures involve forming liposomes from phospholipids, such as distearoyl phosphatidyl-choline or a similar long chain fatty acid diester phospholipid, to be loaded with the drug, e.g., daunorubicin or doxorubicin, in aqueous medium in the presence of an acid, e.g., an organic acid which can be a monofunctional pyranosidyl acid such as lactobionic acid, adding the drug, and then adding a base such as calcium carbonate whose cations cannot pass through the vesicles' bilayers to charge neutralize the organic acid anions in the external aqueous phase and induce the acid anions in the internal aqueous phase to become charge neutralized by attracting the cationic, lipophilic drug.

Abstract: The producing method of  a  chemical  compound  semiconductor device is characterized by simultaneously  growing  two  different dopants to form a single element layer  on  a  substrate  of  GaAs using a molecular beam epitaxy equipment. The  relative  ratio  of molecular beam is larger for one dopant  than  the  other.  Doping concentration of a dopant is controlled by molecular  beam  amount of the other. One dopant is silicon, and the other  is  beryllium. The produced dopant layer is applied to a delta-doped field effect transistor.
