    Notes: Zusammenfassung Zellkinetische Untersuchungen an Ratten nach Injektion von H3-Thymidin ergaben eine rasche Markierung der grossen mononukleären Zellen innerhalb von 20 Min und eine langsaniere Markierung der kleinen Lymphozyten, für welche eine Turnover-Zeit von 23,4 Tagen errechnet wurde. Stündlich gelangen ca. 105 kleine Lymphozyten in die Bauchhöhlenflüssigkeit.

    THE EFFECT OF INTERACTION BEHAVIOR ON SOURCE CREDIBILITY, HOMOPHILY, AND INTERPERSONAL ATTRACTION (1974)

    Notes: This study investigated the relationship between interaction behavior in a small group setting and the resulting perceptions group members have of one another. Trained raters coded the interaction behavior of subjects, who discussed a task-oriented topic in small groups. Results indicate that interaction behavior can account for a substantial percentage of the variance in group members’ perceptions of one another. Apparently, the same interaction behavior may simultaneously result in both more positive and more negative perceptions on the part of other group members, suggesting that different interaction strategies are appropriate for varying desired personal outcomes.

    ASSAY AND SUBCELLULAR LOCALIZATION OF THE ARYLSULPHATASES IN RAT BRAIN (1970)

    Notes: —The properties and subcellular localization of type I (nitrophenyl) and type II (nitrocatechol) arylsulphatases were investigated in brain tissue of the rat, and optimal assay conditions were established. Sulphate, phosphate and sulphite ions inhibited the nitrocatechol sulphatases; nitrophenyl sulphatase was inhibited only by sulphite. The presence of latent enzyme activity was demonstrated for the nitrocatechol sulphatases, beta-glucuronidase, and beta-glycerophosphatase in rat and mouse brain homogenates. These hydrolases were highly sensitive to mechanical and osmotic damage; and Triton X-100 was very effective in releasing their latent (bound) activities, a finding suggestive of a lysosomal localization. Activity of nitrophenyl sulphatase was unaffected by osmotic changes or Triton X-100, characteristics suggesting a membranous association for this enzyme. Total activity of nitrophenyl sulphatase was approximately twice as great in canine gray matter as in canine white matter; the converse obtained for beta-glucuronidase activity. Values for total enzymic activity of the nitrocatechol sulphatases in canine white and gray matter were similar.Fractionation of homogenates from rat brain by differential centrifugations and separation of crude mitochondrial fractions by sucrose density gradient centrifugations revealed the following: (1) most of the nitrocatechol sulphatase activity (93 per cent) and all of the nitrophenyl sulphatase activity were sedimentable; (2) crude mitochondrial fractions exhibited the highest relative specific activity (RSA = 1·38) for the nitrocatechol sulphatases, whereas microsomal fractions displayed the highest RSA for nitrophenyl sulphatase (1·89); (3) the lightest fraction (A + B) and the densest fraction (E) from the sucrose density gradient contained most of the activity for both the type I and type II arylsulphatases, whereas the RSA of cytochrome oxidase was greatest in the intermediate density regions (fractions C and D); (4) the highest RSA for beta-glucuronidase and beta-glycerophosphatase occurred in gradient fraction C; (5) appreciable activity of beta-glycerophosphatase was found in a nerve ending fraction (M3).It is suggested that the hydrolases in heterogeneous tissue like brain might be associated with lysosomal particles of differing enzyme compositions and varying populations, and that the data on distribution lend credence to the concept of bimodal and possible trimodal particle affinity for the hydrolases of brain tissues.

    The birth and demise of a planning unit in a State Mental Health Department (1971)

    Notes: Abstract The development over a five-year period and the sudden dissolution of the Division of Planning and Evaluation Services of a major state department of mental health provides an interesting insight into an effort to establish a rational base of planning in a complex bureaucracy. The characteristics of this division are explored in relation to the rest of the Department of Mental Health as well as its relationship to the State Mental Health Planning Board and its advisory councils. It is felt by the authors that this paper will offer some guidance to others involved in or about to embark upon a similar enterprise.

    Phosphorescence from nylon polymers: Effects of thermal and photochemical oxidation (1974)

    Notes: The phosphorescence from the nylon polymers 6, 66, 11, and 12 has been studied from the aspects of excitation and emission wavelength location and of emission lifetime. In contrast to the other nylons, the 66 polymer exhibits two distinct phosphorescence bands, both of which are sensitive to thermal and photochemical oxidation of the polymer. The species responsible for these emissions are concluded to be carbonyl in nature and their role in the complex reactions that occur during thermal and photochemical oxidation of the polymer is discussed.

    Luminescence from thermally oxidized model amides in relation to nylon 66 degradation (1974)

    Notes: Fluorescence and phosphorescence are observed following the mild thermal oxidation of two model compounds for nylon 66. Both emissions are remarkably similar in structure and in wavelength location to the corresponding emissions normally observed from the commercial polymer. Although the fluorescence could not be characterized, the phosphorescence exhibits several features which are clearly consistent with that of a nπ* carbonyl emission. The role of carbonyl groups in the thermal and photochemical oxidation of nylon 66 is discussed.
