Abstract
A qualitative variant of erythrocyte and liver pyruvate kinases (PK Osaka) was detected in a family in which two siblings have extremely low PK activity by semipurification with DEAE cellulose chromatography and subsequent concentration of the enzyme solutions. This was previously reported to be a quantitative variant based on studies of crude tissue preparations. The molecular aberrations were characterized by slow mobility upon electrophoresis, abnormal kinetics for phosphoenolpyruvate, and low affinity for anti-human erythrocyte PK serum. The mutant PK L was similar both electrophoretically and immunologically to PK R.

Abstract
Isoelectric points of normal human erythrocyte pyruvate kinase (PK) and PK variants with abnormal electrophoretic patterns, were obtained by means of isoelectric focussing. The obtained isoelectric points of normal, PK Nagasaki, PK Tokyo II, PK Ube, and case T.S. were 7.36, 7.38, 7.05, 6.90, and 7.04, respectively, at 6 degrees C. All of the PKs collected after isoelectric focussing were shown to be not of the L-type PK but to be the erythrocyte PK (by means of thin-layer-polyacrylamide gel electrophoresis). The PKs with fast migration had isoelectric points that were shifted to the acidic side as compared with those of the normal subjects. The PK with slow migration had an isoelectric point that was shifted to the alkaline side, demonstrating that the isoelectric points obtained by isoelectric focussing were consistent with the electrophoretic patterns of the crude hemolysates. Isoelectric focussing also revealed the existence of PK variants with abnormal electric net charge, just as well as thin-layer-polyacrylamide gel electrophoresis.

Abstract
The effects of methylazoxymethanol (MAM) acetate on colony survival, cell proliferation and DNA synthesis of murine lymphoma L5178Y cells are studied. Decreased sensitivity and immediate depression of cell proliferation and DNA synthesis were found in L5178Y cells in contrast to the reports on HeLa cells. Pre-labelling with 5-bromodeoxyuridine (BUdR) did not enhance significantly the carcinogen-induced cell lethality. Post-treatment with caffeine greatly enhanced cell lethality and depression of cell proliferation. These effects of caffeine were diminished when the cells had passed through two generations following the MAM acetate treatment. Experiments with synchronized cells showed that the action of caffeine was located primarily in S phase following the MAM acetate-treatment. These results strongly suggest that in L5178Y cells, MAM acetate induces damage, which is repaired by a mechanism analogous to post-replication repair of UV light-induced damage.

Abstract
The electrophoretic mobility and the immunologic specificity of erythrocyte pyruvate kinase (PK) of the homozygous Basenji dog with PK deficiency were identical to those of normal M2-type PK isozyme seen in the white cell but not to those of the erythrocyte PK isozyme. Kinetic properties and stability were also consistent with the M2-type PK isozyme. Defective PK in the homozygous red cell was due to the absence of the erythrocyte PK isozyme and the compensatory presence of M2-type PK isozyme, as seen in the severe classical type PK deficiency in man.

Abstract
The lowering of the viscosity of DNA solution was caused by the action of AsA or EA and facilitated in the presence of CU2+. However, the action of AsA-3-P was very weak. By sucrose density gradient centrifugation, it was observed that single- and double-strand scissions of DNA were provoked by AsA or EA and enhanced with Cu2+, while only a single-strand scission was caused by AsA-3-P and Cu2+. Similar action of AsA or AsA-3-P was also observed for RNA. Thus, the result indicates that the enediol group of AsA takes an essential part in the breakage of nucleic acids, and Cu2+ enhances the action. It was shown that Apu was mainly decomposed by AsA, whereas Apy not, suggesting that some pyrimidine cluster may be one of the regions attacked by AsA. During the reaction with DNA, the reducing activity of AsA decreased first to some extent and then increased, whereas the reducing activity of AsA-3-P was much lower than that of AsA and decreased steadily. The priming activity of DNA for DNA polymerase was changed after treatment with AsA according to the condition. It was enhanced when DNA was treated under mild conditions but decreased with severer action.

Abstract
Four new red-cell pyruvate kinase (PK) variants are presented along with one case of so-called classical type PK deficiency. PK 'Tokyo II' had a low activity, Km (PEP) and Vmax, but a normal urea stability and only slight deviation from normal in neutralization tests by antiserum. It had a normal nucleotide specificity, abnormal electrophoretic mobility (fast moving) and the variant was associated with a mild hemolytic anaemia. PK 'Maebashi' had a low activity, high Km (PEP), low Vmax, urea instability, decreased reactivity to antiserum, normal electrophoretic mobility, normal nucleotide specificity and was associated with a moderate haemolytic anaemia. PK 'Tsukiji' had low activity, high Km (PEP), markedly high Vmax, urea instability, decreased reactivity to antiserum, abnormal electrophoretic mobility (fast moving) and grossly abnormal nucleotide specificity especially abnormal behaviour to ADP. The haemolytic process in this case was moderate to severe. PK 'Ube' was electrophoretically abnormal (fast moving) but otherwise had normal characteristics and the propositus was healthy and not anaemic. PK 'Ube' was found by electrophoretic screening for genetic PK polymorphism. In the classical type PK deficiency, the usual red-cell PK (PK-R1 and PK-R2) was not demonstrable by electrophoresis but instead M2-type PK was present, presumably by compensatory process. Kinetic studies confirmed that the patient's red-cell PK consisted of M2-type PK. This patient had a severe haemolytic anaemia.
