Haemopoietic effects of 7 alpha, 17 beta dimethyltestosterone.

1979

Some haematic parameters were investigated in female COBS mice treated with 7 alpha, 17 beta Dimethyltestcsterone (DMT). The drug causes an increase of circulating platelets in normal mice. Bone marrow graft from DMT-treated donors facilitates in irradiated mice repopulation of white blood cells and platelets but lowers % survival. These data are interpreted on the basis of a commitment and a loss of self-maintenance induced by DMT on CFUs compartment. © 1979 The Italian Pharmacological Society.

Influenza virus-specific T cell-mediated cytotoxicity: integration of the virus antigen into the target cell membrane is essential for target cell fo…

1979

This study deals with the requirements for target cell recognition by influenza A virus-specific cytotoxic T lymphocytes (CTL). H-2-identical cells were incubated with infectious or UV light-inactivated influenza A virus expressing either cleaved or uncleaved hemagglutinin (HA). Thereafter, the treated cells were tested in a 4-h 51Cr assay for susceptibility to CTL-mediated cytolysis. Regardless whether the influenza virus was infectious, virions expressing cleaved HA were efficient in target cell formation. In contrast, cells incubated with either active or UV-inactivated virions expressing uncleaved HA were not lysed by virus-specific CTL. Yet, after mere trypsin-mediated cleavage of the …

Respiratory gas exchange in the rat spleen in situ and intrasplenic oxyhemoglobin saturation.

1979

Measurements of splenic respiratory gas exchange and of HbO2 saturations in the red pulp of the rat spleen have shown that there are no indications of a reduced intrasplenic O2 availability during normoxia. The present studies provide evidence that, in the normal spleen, the intrasplenic sequestration of red blood cells cannot be explained by an O2 deficiency in the red pulp since the commonly accepted notion of an intrasplenic hypoxia is not true.

1979

Abstract A stable and homogeneous adenosine-5ʹ-triphosphatase (ATPase, EC 3.6.1.3) has been solubilized from Rhodospirillum rubrum (R . rubrum) chromatophores by chloroform extraction. Purification of the Ca2+-dependent ATPase activity was 200-fold. Ca2+ can be replaced by Mg2+, Cd2+, and Mn2+ .The Km for Ca-ATP (0.17 mᴍ) is increased about 5-fold during solubilization of the enzyme, whereas the Km values for Mg-ATP (0.029 mᴍ) and Cd-ATP (0.014 mᴍ) are not affected. The chloroform-released ATPase has a molecular weight of 400,000 ± 30,000 and consists of the following subunits (molecular weights in parenthesis): α (58,000), β (53,500), γ (39,000), δ (18,500), and ε (14,000).

Induction of rat hepatic epoxide hydratase by dietary antioxidants

1979

Abstract Supplementation of rat diet with butylated hydroxytoluene (BHT), butylated hydroxyanisole, or ethoxyquin resulted in increased liver epoxide hydratase activity. The increase was obvious at 0.1% and amounted to 200–400% at 0.5%. Increased activity was accompanied by increased proportion of the epoxide hydratase band in SDS polyacrylamide gels, indicating induction of the enzyme. Ethoxycoumarin deethylase activity and cytochrome b5 concentrations were moderately elevated while cytochrome P-450 concentrations and aryl hydrocarbon hydroxylase activity remained at control levels. Preferential inhibition of monooxygenase activity by metyrapone and not 7,8-benzoflavone, as well as increas…

Oxidation of tertiary amines with N-chloronylon 66 (NCN) was investigated in several organic solvents. NCN was found to oxidize N,N-dimethylaniline (DMA) at room temperature to give N-methylaniline with 15–50% yield, depending on the solvents used. Oxidation of N,N-dimethylbenzylamine (DMBA) gave benzaldehyde with 15–30% yield and a small amount of N-methylbenzylamine. A mechanism was discussed. For comparison, N-chlorosuccinimide, a low molecular N-chloro-compound, was also used for oxidation of DMA and DMBA.

The static dielectric constant of solutions of water inn-alcohols at 15, 25, 35, and 45°C

1979

Dielectric constants (measured at 1 MHz) are reported for solutions of water (concentration range 0 to 0.2 mole fraction) in 1-propanol at 25°C, and in 1-butanol, 1-pentanol, and 1-hexanol at 15, 25, 35, and 45°C. These results, together with literature values for solutions of water in methanol, ethanol, 1-heptanol, and 1-octanol, show that water interacts with alcohols in at least two ways: (1) it can participate in the formation of dynamic hydrogen-bonded chains, thereby raising the polarizability; (2) it can form relatively stable structures such as H2O(ROH)4 which have zero net dipole moment and consequently diminish volume polarizability. For C n H 2n+1 OH alcohols,n≥4, most of the ini…

A combination intermediate-image magnetic plus Si(Li) electron spectrometer for in-beam experiments

1979

Abstract A magnetic lens plus Si(Li) combination in-beam beta spectrometer with focusing properties and field shape similar to those of an intermediate-image spectrometer is described. A high transmission and a large momentum band-width are achieved by placing both the target and the detector in a high magnetic field inside the lens. The beam enters the lens axially, and the Faraday cup is placed inside the lens. The spectrometer is well suited to singles conversion-electron spectroscopy, to electron-heavy particle coincidence measurements, to lifetime measurements and to studies of internal-pair transitions.

Pain-induced alterations in the individual non-esterified fatty acids in serum.

1979

Changes of individual non-esterified fatty acids in serum were studied in 7 metabolically healthy patients, suffering from idiopathic trigeminal neuralgia, who underwent electrocoagulation of gasserian ganglion under neurolepthypalgesia. The mean concentration of fatty acids increased by about 40% during the strong surgical pain stimulus. The increased lipolysis affected all individual fatty acids in proportion to the ratio of their presence in adipose tissue. The mechanism of pain-induced activation of lipase and possible consequences of alterations in individual non-esterified fatty acids are discussed.

Reduction of benzo(a)pyrene mutagenicity by dihydrodiol dehydrogenase

1979

THE enigma of how inert chemicals can exert potent mutagenic, carcinogenic, allergenic and cytotoxic effects has been much debated. It has been learned that such compounds are metabolically converted to chemically reactive species1. In the case of aromatic or olefinic compounds, monooxygenases located in the membranes of the cell can transform these compounds into epoxides2–5 which by virtue of electrophilic reactivity can bind chemically to cellular macromolecules such as DNA, RNA and proteins, thereby disturbing biochemical control mechanisms and leading to the above mentioned toxic effects. The same membranes in which such epoxides are produced possess an enzyme, epoxide hydratase, which…

2D NMR spectra have been measured at variable temperatures between −100°C and +110°C in a sample of melt crystallized deuterated polyethylene (PE). The line shape could be decomposed into a central part originating from deuterons in the amorphous regions and outer parts from crystalline regions of PE. The “NMR crystallinity” determined from this separation was 72% in agreement with the X-ray crystallinity of 74%. Changes of the crystalline NMR line shape were interperted in terms of oscillations around the chain axis, the r.m.s. oscillation amplitude varying from 5° at 40°C to 12° at 110°C. The central part of the NMR line shape indicates the existence of a “narrow” and a “medium” component…

Messenger RNA of the large subunit of ribulose-1,5-bisphosphate carboxylase from Chlamydomonas reinhardi. Isolation and properties.

1979

Polysomes specifically synthesizing the large subunit of ribulose-1,5-bisphosphate carboxylase were isolated from Chlamydomonas reinhardi cells by the indirect immunoprecipitation method. Electrophoretic analysis showed that the immunoprecipitated polysomes were of chloroplast origin. The mRNA coding for the large subunit which was purified from immunoprecipitated polysomes migrated at the 19-S position on sucrose density gradients, and its molecular weight was estimated to be 7.3 x 10(5) by acid-urea/agarose gel electrophoresis. The mRNA was translated in vivo with a cell-free protein-synthesizing system derived from Escherichia coli to give full-length large-subunit polypeptides.

Depressed Prostaglandin Release from Peritoneal Cells Induced by a T Cell Adjuvant, Lentinan

1979

Abstract PGE and PGF release from peritoneal exudate cells was studied in mice after injection with two s (1–3) glucans, the antitumor active lentinan and the inactive pachyman. 4 days after injection of both polysaccharides, the spontaneous and phagocytosis-induced PGE and PGF release was markedly suppressed. However, only the immunopotentiator lentinan induced peritoneal exudate cells which exhibited a longer lasting diminished PG release. The data suggest that the T cell adjuvant lentinan may potentiate cellular immune responses by reducing synthesis of immune suppressive prostaglandins from peritoneal exudate cells.

Naturally occurring hemolysins in the coelomic fluid of Holothuria polii delle chiaie (Echinodermata).

1979

Abstract The coelomic fluid of Holothuria polii D.Ch contains hemolytic activity against erythrocytes of several vertebrate species. The hemolytic potency depends upon calcium ion concentration and varies according to erythrocyte source and cell number in the reaction mixture. Absorption experiments with formalinized rabbit erythrocytes suggest that hemolytic activity is not specific. Its heat lability, water insolubility at low pH values, and sensitivity to proteolytic enzymes suggest that hemolytic activity resides in protein molecules. The activity, maximal in alkaline media, appears to depend up time and temperature.
