    Abstract: Many potentially valuable techniques for the understanding of human neurobiological and neuropathological processes require the use of RNA obtained from postmortem tissue. As with earlier neurochemical studies, there are two particular problems posed by such tissue in comparison with tissue from experimental animals. These are the postmortem interval and the condition of the patient prior to death, referred to as the agonal state. We review the nature and extent of the effects of postmortem interval and agonal state on RNA in brain tissue, with particular reference to the study of neuropsychiatric disorders. Perhaps surprisingly, postmortem interval has at most a modest effect on RNA. Abundant intact and biologically active RNA is present in tissue frozen 36 h or more after death. Postmortem interval does not account for the marked variability observed among human brains in all RNA parameters. Despite the overall stability of RNA after death, some evidence suggests that individual RNAs may undergo postmortem decay. Less attention has been paid to the effects of agonal state. The existing data indicate that events in the premortem period such as hypoxia and coma can affect the amount of some messenger RNAs. The nature of agonal state influences depends on the messenger RNA in question, though the basis for this selective vulnerability is unknown. No agonal state effect on overall RNA level or activity has been found. The data show that postmortem brain tissue can be used for RNA research. However, considerable attention must be paid to controlling for the influences of pre-and postmortem factors, especially when quantitative analyses are performed.

    Abstract: Acetyl-coenzyme A: choline O-acetyltransferase (EC 2.3.1.6) (ChAT) enzyme activity was measured in the nucleus basalis and other microscopically identified brain areas at various times after unilateral cortical lesions were made in the rat. Initially, a significant decrease in ChAT activity was detected in the nucleus basalis ipsilateral to the lesion. However, after 120 days ChAT activity had apparently recovered, as levels of the enzyme at that time were not significantly different from control values. No changes in ChAT activity could be detected in any of the other brain areas similarly studied. The significance of these findings and their relationship to the morphological changes seen in neurones of the nucleus basalis after cortical lesions are discussed.

    Abstract: There are conflicting data regarding alterations in β-amyloid precursor protein (APP) mRNAs in Alzheimer's disease (AD). This may be due partly to variables such as agonal state and choice of control group. We have used in situ hybridization histochemistry to study expression of APP mRNAs, with and without the domain encoding the Kunitz protease inhibitor, in a way that overcomes some of the limitations of the current data. Tissue from frontal cortex was collected at rapid autopsy from patients with AD or other cognitive impairments whose terminal phase was prospectively assessed. There were three main findings. Firstly, the amount of APP mRNAs correlated strongly with glutamate decarboxylase activity and was reduced in association with terminal pyrexia. These correlations suggest that agonal state affects APP mRNA and, therefore, that differences in premortem course may contribute to the varying changes in APP transcript abundance reported in AD. Secondly, a reduction of both forms of APP mRNA, normalized to polyadenylated mRNA, was found in AD compared with normal controls and with non-AD dementias. This supports findings that the APP-related pathology of AD is not due to overexpression of APP mRNA or an altered proportion of Kunitz protease inhibitor-containing isoforms. Thirdly, the amount of APP mRNA correlated inversely with that of heat-shock protein (hsx70) mRNA. This relationship was unexpected given current theories that APP expression occurs as part of a stress response, and suggests that other factors predominate in determining neocortical APP mRNA content in neurodegenerative disorders.

    Notes:
    High resolution IR spectra of the linear HCCCN–HCCH and HCN–HCCCCH hydrogen bonded complexes have been obtained using optothermal detection molecular beam techniques. Two vibrational bands have been observed for each complex, which correspond to the terminal "free'' C–H stretch vibrations (ν2) of the cyano units and the hydrogen bonded vibrations (ν3) of the acetylenic CH stretches. For both complexes, accurate molecular constants have been obtained. Furthermore, predissociation lifetimes for the ν3=1 states of the both complexes have been determined. The results are compared with those of the linear HCN–HCCH complex obtained by Block et al. [Chem. Phys. 139, 15 (1989)]. © 1996 American Institute of Physics.

    SUMMARY 1. Experiments using implanted substrata were conducted in Yuccabine Creek, a n upland stream in north-eastern Australia which exhibits a strong seasonal pattern of discharge and temperature. The implanted substrata were either set in the stream bed or were raised in the water column. Three experiments were run, at different times of the year.2. Colonization rate was dependent on benthic abundance, mobility of the fauna and distribution of resources. The rates on embedded trays were similar in the late wet season and mid dry season, but colonization rate in the late dry season was greater.3. Drift alone could have accounted for all colonization in the late wet season, 63% of colonization in the mid dry season and less (unmeasured) in the late dry season. Drift acts to disperse early instars to patches of suitable habitat after the summer wet-season peak in reproduction.4. Following the wet season, stream discharge decreases, benthic abundance increases, resources become more concentrated, and movements of animals in contact with the substratum play an increasingly important role in colonization.

    SUMMARY 1. Trays of gravel were implanted for 24 h periods in several chalk streams. The trays were variously modified to monitor colonization from different sources, particularly drift (D), other downstream movements (DSM), upstream movements (USM), and all sources combined (ALL).2. The abundance of invertebrates in the streams was high (maximum of 717 per 0.04 m2) and colonization of the trays was extensive, especially by Gammarus pulex, the predominant species in all but one of the streams (maximum number of individuals of G. pulex per tray: for D, 473; for DSM, 462; tor USM, 286; and tor ALL, 639). In some cases benthic densities were achieved in the trays in the 24 h exposure period, and in most cases any one source of colonization could provide benthic densities in a few days.3. Patterns of movement differed between species, between size classes of G. pulex, and between sites for particular species. No one source of colonization could be regarded as generally predominant although downstream movements in total (D + DSM) usually far exceeded USM. DSM was usually an important source of colonization.4. The extent and direction of movement appeared to be determined by local factors and were explained in terms of the high densities of invertebrates and the current and substratum characteristics of each site.5. Estimates of the relative importance of different sources of colonization varied greatly according to the criteria used in determining proportions.

    Notes:
    Unilateral lesions of the rat frontal cortex were made either alone or in combination with the caudate-putamen in order to examine (a) their morphological influence on the substantia nigra and (b) their neurochemical influence on GABA function in the superior colliculus. One to two months following the combined lesion, neuronal somata in the ipsilateral pars reticulata of the substantia nigra were clearly hypertrophied (+ 30%). Morphological changes in the substantia nigra were not evident contralateraly or in animals bearing only cortical lesions. One to two months following cortex-only lesions, no significant alterations in tectal GABA concentration were observed. However, the combined lesion induced elevations of GABA within both the medial and lateral sectors of the intermediate and deep layers of the superior colliculus. This effect was restricted to the ipsilateral side and was most pronounced in lateral sectors. The vast majority of GABA released from superfused control tectal slices by a depolarizing stimulus (35 mM KCI) was calcium-dependent. Such evoked GABA release from ipsilateral tectal slices was significantly reduced (-25%) by unilateral lesions of the substantia nigra, a structure that is known to provide GABA-containing inputs to the tectum. In contrast, cortical lesions alone significantly enhanced the evoked tectal GABA release (+ 66%), although their influence was again confined to the ipsilateral side. Combined lesions of the cerebral cortex and caudate-putamen significantly enhanced the evoked GABA release from tectal slices in both hemispheres but the changes were most marked ipsilaterally (+ 147%). It is suggested that the hypertrophy of GABA-containing nigrotectal somata seen after removal of corticostriatal, corticotectal and in particular GABA-containing striatonigral fibres may reflect concomitant increases in GABA synthesis within and/or sprouting of nigrotectal terminals.
