Using dilutions 1/1-1/16 of different thromboplastins and undiluted plasma, the prothrombin times were longer with the increase of dilutions. When plasma was diluted in saline or buffer (1/5/1/10), a proportional shortness of the clotting times were observed. With adsorbed plasma as diluent a progressive lengthening of the prothrombin times were obtained, related with the clotting times of the undiluted plasmas. Express as ratios, all thromboplastins showed shortness when plasma was diluted with saline or buffer but rather constant values with adsorbed plasma dilutions. Then, thromboplastins were concentrated and, although times of undiluted plasmas were rather similar, the ratios of the different concentrations of tissue extract, considering the 1/10 dilution of plasma, were different. In terms of the so called “sensitivity” this means a better sensitivity when thromboplastin concentration was increased. Similar results were achieved when thromboplastin was additionated with fenol. We concluded that many tissue extracts may achieve a “good sensitivity” by increasing it concentration in the test tube Why plasmas diluted with adsorbed plasma gives constant ratios, remains unknown for us. We feel that standardization of thromboplastin should be made on more biochemical basis.

The kidney of guinea pigs infected with the H37Rv and BCG strains of M. tuberculosis showed a diminution in succinic dehydrogenase activity when measured by the tetrazolium technique. This effect was also seen in the liver and spleen of animals infected with the BCG strain. Sensitized animals showed similar results when given tuberculin in sublethal doses. The succinic oxidase was also low in the kidneys of animals infected with the H37Rv strain. The depressed enzyme activity of the tissues of infected animals could be restored to normal by addition of normal tissue extract or dialysate. This suggests that the alteration in tissue metabolism observed in tuberculosis may depend upon the loss of some as yet unidentified factor important for succinic dehydrogenase activity.
