Title: Ion concentration measuring and reference electrodes
IPC: G01N27/333
Filed: 1979-02-14
Abstract: A solid state ion concentration measuring electrode comprises a coherent pellet 2 of electrolyte and an ion selective layer 10 or 40 formed in direct contact with the pellet surface. The electrodes may be formed by compression moulding the electrolyte pellet around a terminal and then forming the ion selective layer by sputtering. For an ion selective electrode, layer 10 is formed of ion selective glass of similar thermal expansion coefficient to layer 2D. For a reference electrode, the temperature expansion of the glass 30A and layer 2C are selected to produce a differential expansion causing random cracking of the glass layer 40 during temperature cycling of the reference electrode. A combination structure is provided wherein the ion concentration measuring electrode and the reference electrode are combined in an integrated package. A thermal compensating element 50 may also be included in the integrated package. <IMAGE>

Title: Liposomes containing antimony anti-leishmanaisis drugs
Inventor: RAO LEBURU SESHAGIRI
IPC: A61K9/127
Filed: 1982-08-09
Abstract: Anitomy-containing anti-leishmanaisis drugs are encapsulated in a lipid based liposomal formulation having a weight ratio of lipid to encapsulated antimony-containing drug of 1:1.6 to 1:0.25 and a salt concentration in the continuous aqueous phase which is at least isotonic with human blood. Such formulations are found to have a leakage rate of initially encapsulated anitomy-containing drug of less than 50% by weight after storage at 25 DEG C for 6 weeks from encapsulation and hence provide storage stable formulations which can be used effectively after prolonged storage without refrigeration in tropical climates. The liposomal formulations are preferably prepared by a reverse phase evaporation method involving first emulsifying an aqueous solution of the drug with an organic solvent solution of the lipid and then removing the organic solvent at reduced pressure at a temperature below the normal boiling point of the solvent but above the phase transition temperature of the lipid.
