    Graft-derived recovery from 6-OHDA lesions: specificity of ventral mesencephalic graft tissues (1988)

    Notes: Summary A series of experiments have been conducted to assess the specificity of recovery from motor asymmetries that is provided by dopamine-rich grafts in the neostriatum of rats with unilateral dopamine-depleting lesions produced by injection of 6-hydroxydopamine into the ascending nigrostriatal pathway. Grafts of embryonic tissue taken from the substantia nigra (rich in dopamine neurons) could provide a complete recovery of methamphetamine-induced rotation and a partial recovery of apomorphine-induced rotation, whereas no recovery was seen in rats with grafts of tissue rich in another monoamine (serotonin, dissected from the mesencephalic raphe) or of tissue appropriate to the target (dissected from the striatal eminence). 6-Hydroxydopamine lesions of dopamine cells in the grafts of recovered animals reinstated the initial lesion-induced asymmetry. Dopamine-rich grafts implanted into the intact neostriatum did not induce any “supernormal” asymmetry in the rats, but did provide a “prophylactic” protection against subsequent lesions of the intrinsic ipsilateral dopamine nigrostriatal system. Post-mortem biochemical assays indicated that the extent of dopamine depletion in the neostriatum of lesioned rats correlated highly with both methamphetamine and apomorphine turning rates. Similarly, both drug rotation tests correlated significantly with the extent of dopamine restoration in the dorsal striatum of rats with dopamine-rich grafts, the correlation being significantly higher for the methamphetamine than for the apomorphine test.

    Conditioned locomotor activity but not conditioned place preference following intra-accumbens infusions of cocaine (1992)
    Springer
    Psychopharmacology 106 (1992), S. 330-336 
    Details
    ISSN: 1432-2072
    Keywords: Conditioned place preference ; Conditioned locomotor activity ; Cocaine ; Amphetamine ; Nucleus accumbens ; Reward ; Rat

    Topics: Medicine
    Notes: Abstract In the first experiment, the conditioned place preference (CPP) paradigm was used to examine the rewarding properties of bilateral microinfusions of cocaine HCl into the nucleus accumbens (0, 12.5, 25, 50, or 100 µg). No dose of intra-accumbens cocaine induced a significant CPP. However, bilateral intra-accumbens infusions ofd-amphetamine sulfate (10 µg) or intraperitoneal administration of cocaine HCl (5 or 10 mg/kg) both produced a significant preference for the drug-paired compartment. In the second experiment, the ability of bilateral intra-accumbens infusions of cocaine HCl (50 µg) to elicit conditioned locomotor activity (CLA) was examined. During the conditioning trials, intra-accumbens cocaine significantly increased locomotor activity. On the test day, when no drug was administered, the group that had previously received cocaine in the activity chamber showed significantly greater locomotor activity than the vehicle control group. This demonstration of CLA indicates that rats are able to associate the effects of intra-accumbens infusions of cocaine with environmental stimuli; however, these infusions are not rewarding as measured by the CPP paradigm. In addition, these results may indicate important differences between the neural substrates for cocaine and amphetamine reward and reveal a dissociation between CPP and CLA.

    Comparative Analysis of Crossover Exchanges and Chiasmata in Allium Cepa × Fistulosum After Genomic In Situ Hybridization (GISH) (1998)
    Springer

    Keywords: Allium ; chiasmata ; crossing over ; genomic in situ hybridization ; recombination

    Topics: Biology
    Notes: Abstract Genomic in situ hybridization (GISH) successfully differentiated homoeologous genomes in the interspecific hybrid Allium cepa × fistulosum, thus allowing the detection of reciprocal crossover events as label exchanges in separating anaphase I chromosomes. Three of the eight chromosome pairs were positively identified by fluorescence in situ hybridization (FISH) to rDNA sequences. There was a general similarity of the GISH-based label exchange frequencies and metaphase I chiasma frequencies, but with a 20% deficit of chiasmata. Reasons for this apparent deficit are discussed. The locations of chiasmata and label exchanges are in broad agreement.

    Distribution of a 375 bp repeat sequence inAllium (Alliaceae) as revealed by FISH (1999)

    Notes: Abstract Information about evolutionary relationships between species of the genusAllium is desirable in order to facilitate breeding programmes. One approach is to study the distribution of repetitive DNA sequences among species thought on taxonomic grounds, to be closely related. We have used fluorescent in-situ hybridisation (FISH) to examine seven species within sect.Cepa of the genus (A. altaicum, A. cepa, A. fistulosum, A. galanthum, A. pskemense, A. oschaninii andA. vavilovii), one species from sect.Rhizirideum (A. roylei), two species from sect.Allium (A. sativum andA. porrum) and one species from sect.Schoenoprasum (A. schoenoprasum). Each species was probed using a 375 bp repeat sequence isolated fromA. cepa (Barnes & al. 1985), which was generated and labelled by polymerase chain reaction (PCR). No signals were detected in anyAllium species not belonging to sect.Cepa with the exception ofA. roylei, whose designation in sect.Rhizirideum is now questioned. Within sect.Cepa the probe was found to hybridize to the ‘terminal’ regions of the chromosome arms of all the species examined. In addition a number of interstitial bands were detected. Use of FISH reveals a more detailed map of the location of the repeat sequences than has previously been obtained by C-banding and other staining procedures. The distribution of the terminal and interstitial sites when compared, allow us to identify three species groups namely,A. altaicum andA. fistulosum; A. cepa, A. roylei, A. oschaninii andA. vavilovii; andA. galanthum andA. pskemense.
