Initial Decrease

Changes in the level of protein and in the activity of acid phosphatase in seeds of <i>Lupinus luteus</i> L. and <i>Lupinus angustifolius</i> L. during storage and germination were studied. The protein level decreased during germination, mainly as the result of a fall in the concentration of β-conglutin. After an initial decrease in the activity of acid phosphatase activity during the first five days of germination, the activity of this enzyme began to rise with the appearance of two new molecular forms. No significant effect of gibberelin A3 on the specific ativity of acid phosphatase was observed.

Important Site

Hemolytic anemias were produced in rats by administering phenylhydrazine or anti-erythrocytic (rooster) serum, the latter having agglutinin and hemolysin titers exceeding 1:1000.Following administration of phenylhydrazine, the erythrocytes undergo oxidative damage and are removed from the circulation by the cells of the reticulo-endothelial system, predominantly by the spleen. With increasing dosage or if animals are splenectomized, the Kupffer cells become an important site of sequestration and are greatly hypertrophied. Whole red cells are the most common type engulfed; they are broken down in digestive vacuoles, as shown by the presence of acid phosphatase activity (Fig. 1). Heinz body material and membranes persist longer than native hemoglobin. With larger doses of phenylhydrazine, erythrocytes undergo intravascular fragmentation, and the particles phagocytized are now mainly red cell fragments of varying sizes (Fig. 2).
