    Notes:
    Single toxic doses of l-methyl-4-phenyl-l,2,3,6- tetrahydropyridine (MPTP)-HCI (2.5 mg/kg i.v.) and 4′- amino-MPTP · 2HCI (22.5 mg/kg) induce loss of striatal dopamine (DA) and tyrosine hydroxylase (TH) activity and of nigral DA neurons in the dog. To examine the subacute neurochemical changes induced by low doses of MPTP and 4′- amino-MPTP, dose-response studies of these compounds were carried out in the dog, using 6- and 3-week survival times for these two compounds, respectively. Low single doses of MPTP (1.0, 0.5, and 0.1 mg/kg i.v.) and 4′-amino-MPTP (15, 7.5, and 3.75 mg/kg i.v.) did not cause depletion of canine striatal DA or TH or a loss of nigral neurons. However, levels of the DA metabolites 3,4-dihydroxyphenylacetic acid (DO- PAC) and homovanillic acid (HVA) were decreased in a doserelated fashion, with significant loss of DOPAC being evident 6 weeks after the lowest administered dose of MPTP and 3 weeks after 4′-amino-MPTP. This selective loss of DA metabolites following nontoxic doses of MPTP and 4′-amino- MPTP led to a shift in the ratio of DA to DOPAC or HVA, which was characteristic for each compound. The measurement of striatal l-methyl-4-phenylpyridinium (MPP+) and 4′-amino-MPP+ levels revealed that high concentrations (up to 150 μM) persist in the striatum for weeks following administration of a single nontoxic dose of MPTP or 4′-amino- MPTP. A causal relationship between the striatal concentration of MPP+ or 4-amino-MPP+ and the change in DA metabolism as reflected in the DA/DOPAC ratio is suggested by a significant correlation between these measures. It is suggested that presynaptic sequestration and retention of MPP+ and 4′-amino-MPP+ by striatal DA terminals result in the inhibition of the monoamine oxidase contained within these terminals.

    Abstract A short survey of methods and apparatus arrangements used for measurement of vapor pressure by means of radioactive isotopes is given here. A description is given of vapor pressure determination by the static method, through the direct measurement of radioactivity in the vapor by a counter, or through the determination of activity by radiographic and chemical means. Work on measurement of vapor pressure along the lines of the boiling point method and the jet method, is presented. On the basis of two works, the method of Langmuir in the variant of vaporization of matter from a thin wire and vaporization from a crucible, is discussed. The vapor ressure of liquid metals and of components of liquid alloys is derived from the activity of the condensate. A variation of this method is described, in which the vapor pressure is determined from the activity of part of the condensate. Integral (with collection of all vapor), and differential (with collection of only part of the vapor phase) variations of Knudsen's method are presented, as well as the results of measurement of vapor pressure of elements and components of alloys by means of radiometric analysis of ccndensate. In the last section a description is given of measurements of vapor pressure by the method of isotope exchange. A table is given of relative sensitivity of vapor pressure measurement by the various methods.

    Notes:
    Abstract It is becoming increasingly important that a Geographical Information System delivers high performance to efficiently store, retrieve and process the voluminous data that it needs to handle. It is necessary to employ processing and storage parallelism for scalable long‐term solutions. With the demise of many custom‐built parallel machines, it is imperative that we use off‐the‐shelf technology to provide this parallelism. A closely‐coupled network of workstations is a viable alternative. This paper shows that a distributed index structure spanning the workstations can provide an efficient shared storage structure that can be used to get to the geographic information distributed amongst the individual disks and memories of the workstations. This goal can be attained without significantly compromising on the time taken to build this structure.
