    Notes: This study was designed to investigate the interrelationships betwen personility variables measured by both the Blacky Pictures and the Defense Preference Inquiry, and epinephrine-like and norepinephrine-like blood pressure reactions to intramuscular Mecholyl.Thirty hospitalized, open ward, male, acute, psychiatric patients were used as subjects. To evaluate the degree of relationship, phe coefficients were computed betwen the two blood pressure categories and the twenty-two personality dimensions.A norepinephrine-like blood pressure reaction to Mecholyl was associated with a rether primitive and infantile personality constellation, characterized by a tendency to utilize regression and projection as preferred ego defences. The epinephrine-like blood pressure to Mecholyl was related to a strong attachment to mother, a lesser tendency toward regression, and the utilization of reaction formation as the preferred ago defense.The results of this study were quite similar to that previously reported by Funkenstein. Thus, the present data give further support to the hypothesis that the way an individual characteristically adjusts at the physiological level to a chemical stres is related to his underlying personality structure, and to his characteristic way of handling psychological stress.

    Notes: Summary Thiobacillus thiooxidans was grown at constant pH. No growth was obtained above pH 4.3. Sulfur was oxidized over the entire range tested (pH 0.9 to 7.0). This was confirmed by pH shift experiments. Carbon dioxide fixation stopped 30 min after shift from low pH to neutral values. On return to high acidity, the rate of CO2 assimilation increased but not always to the original value. The intracellular binding of glycerol which is passively permeable was also inhibited by raising the pH of the medium. The data suggested that ATP formation may be inhibited at neutral pH. Intracellular ATP pool was reduced by 80% on neutralization of the acid growth medium. These results are compared to recent studies on acid-base transients in T. novellus by Cole and Aleem (1971).

    Notes: Summary Analysis of recent and older published data of many investigators indicates that in prokaryotic organisms normally found in environments at atmospheric pressure, the major biological process which is most sensitive to increased hydrostatic pressure is protein synthesis and its inhibition approximately parallels that for growth under the same physical conditions.

    Notes: Summary Catalase induction in Rhodopseudomonas spheroides and three locally isolated strains of Rhodopseudomonas (TL-1, TL-4 and Rps. D) was studied. A correlation between the rate of excretion of porphyrin and the inducibility of the culture was observed. 8-hydroxyquinoline at 4x10-5 M had no effect on Bchl synthesis but it inhibited porphyrin excretion and catalase induction in Rhodopseudomonas spheroides. 8-OH Q at this concentration partially inhibited Bchl synthesis and catalase induction in strain TL-1. The data indicate that the amount of catalase produced is dependent on the pool size of porphyrins.

    Notes: Summary The effect of inhibitors of carotenoid synthesis, diphenylamine, acridine, and acriflavin on catalase induction was studied in Rhodopseudomonas spheroides. The induction of catalase by 40 μM H2O2, was inhibited 5x10-4 M acridine, 5 μM acriflavin and 3x10-4 diphenylamine. Acridine, acriflavin and diphenylamine at 1.0x10-4 M, 1.5 μM and 5x10-5 M respectively, stimulated the induction. The stimulatory effect was shown to be at the transcriptional level rather than at the translational level. The concentration of acridine which stimulated the induction of the enzyme inhibited general protein synthesis in the cell, under similar conditions. Acriflavin also did not stimulate the induction of β-galactosidase in Escherichia coli B. It is suggested that these acridine dyes interact with the internal inducer-DNA complex which leads to a higher rate of production of catalase mRNA.
