The epsilon-amino groups of ovalbumin were modified with succinic anhydride; as many as 16 lysine residues were succinylated (3-carboxypropionylated). The five succinylated derivatives thus prepared were homogeneous with respect to the extent of chemical modification as shown by electrophoretic and immunological data. Succinylation of the amino groups(More)
Hydatid fluid collected from the lungs and livers of sheep and humans was analysed for protein and lipid composition. There were no marked differences in the composition of these parameters and the major lipids were triglycerides and diglycerides. The phospholipids, which formed the minor fraction, were mainly phosphatidyl choline and phosphatidyl inositol.(More)
The mechanism for the air in the mediastinum is suggested as being due to rupture of marginal pulmonary alveoli, allowing the development of pulmonary interstitial emphysema. This then tracks through the fascial planes at the lung hilum, and from there into the mediastinum and neck. There was no obvious underlying lung disease in our patient, and no further(More)
A procedure is described for the specific acetylation of the lysine residues of ovalbumin. Six acetylated ovalbumins varying in the degree of modification from 21 to 98% were prepared and were found to be homogeneous by polyacrylamide gel electrophoresis, immunodiffusion, and immunoelectrophresis. As expected, the anodic movement of ovalbumin increased and(More)
A method described for large scale cultivation ofEntamoeba histolytica axenically in a modified Diamond’s TP-S-1 monophasic medium. Crude amoebaantigen prepared by the ultrasonication of the trophozoites ofE. histolytica, was fractionated by sephadex G-200 column into four different fractions. The whole antigen and its different fractions were freeze-dried(More)
