    Notes: Summary The anticancer agent 1,3 Bis(2-chloroethyl)-1-Nitrosourea (BCNU) cures the advanced syngeneic LSA lymphoma of C57BL mice with high efficiency. The cured animals resist further tumor challenge by large numbers of viable syngeneic tumor cells. Growth assays of spleen proliferation of the intravenously inoculated tumor revealed a progressive-regressive pattern of spleen growth after LSA-tumor injection. Lymphoma colony forming units (LCFU) in the spleen initially increased then regressed. In vitro assays of serum showed a alack of cytotoxic activity in mice cured by BCNU. Added spleen, thymus, or bone-marrow cells were similarly ineffective. Spleen and bone-marrow cells from immune mice passively transferred to normal mice showed weak cytotoxic activity against the LSA tumor. BCNU-cured mouse cells were more effective in protection than those cured with Chlorozotocin (CLZ).

    Notes: Summary Rabbit cardiac muscle sarcoplasmic reticulum (SR) was isolated and separated into ryanodine-sensitive and-insensitive fractions (L.R. Jones and S.E. Cala,J. Biol. Chem. 256:11809–11818, 1981). Vesicles of cardiac SR were incorporated into planar phospholipid bilayers by fusion and the channel activity of the membrane studied under voltage-clamp conditions (C. Miller,J. Membrane Biol. 40: 1–23, 1978). Both fractions contain a monovalent cation-selective three-state channel. In the presence of 75mm K2SO4, the fully open state (β) conductance of this channel is 157.2±30 pS and the sub-state (α) conductance is 100.7±21 pS. Both open states display the same selectivity sequence for monovalent cations, i.e. K+〉NH 4 + 〉Rb+〉Na+〉Li+ and may be blocked by the skeletal muscle relaxants decamethonium and hexamethonium. Block occurs when the compounds are added to either side of the membrane. The properties of the cardiac SR cation channel are compared with those of the previously reported monovalent cation-selective channels of mammalian and amphibian skeletal muscle SR.

    Description / Table of Contents: Anwendung der, „Conversion Electron Mössbauer Spectroscopy“ (C. E. M. S.) auf die Untersuchung der Inhibierung der Korrosion in Kondensatorrohren aus MessingBeschrieben wird der Aufbau eines einfachen Zählers zur Aufnahme des „Conversion Electron Mössbauer-Spektrums“ der inneren Oberfläche eines Rohres. Die Zählvorrichtung wird benutzt zur Untersuchung des Einflusses von Eisen-II-Sulfatzusatz als Inhibitor in Kühlwasser für Kondensatorrohre aus Messing. Aufgrund der Ergebnisse führt these Behandlung zur Bildung einer FeOOH-Schicht auf der inneren Rohroberfläche; die genaue Zusammensetzung der Schicht unterscheidet sich geringfügig je nach den örtlichen Verhältnissen.
    Notes: The construction is described of a simple counter for measuring the conversion electron Mössbauer spectrum of the inside surface of a tube. The counter is used to investigate the effects of adding ferrous sulphate to the cooling water of condensers with brass tubes to inhibit corrosion. It is concluded that the treatment leads to the formation on the inside of the tube of a layer of FeOOH, the exact nature of which depends slightly on the local conditions.
