The dopamine system in weaver mutant mice (BGCBA-AwmJ/A background) was studied. Dopamine was 27% lower in the olfactory tubercle, 77% lower in the frontal cortex, and 75% lower in the striatum of 6-month-old weaver mice compared to control mice of the same age. Norepinephrine and serotonin were not lower in these brain areas. Tyrosine hydroxylase activity in the striatum was measured with a ra...

an inhibitory modulator of cholinergic and noradrenergic neurotransmission (Miller et al., 1999; Van Hoomissen et al., 2004; Landry et al., 2005; Hobson et al., 2006). Gal is co-localized with norepinephrine (NE) in several regions of the brain, such as locus coeruleus, bed nucleus of the stria terminalis, amygdala, cortex and hippocampus (Hokfelt et al., 1998; Kozicz, 2001; Xu et al., 2001; Ho...

Following the works of Velazquez et al. (1999), Jo-Seung et al. (2000), Wang et al. (2001), Danscher et al. (2001) and the criteria of Zinc-containing neurons established by Frederickson et al.(2000), we have found the presence and localisation of Zinc in the neurons of the dorsal root ganglia of Wistar rat, by using Timm's thecnique and by studying the autoradiographic uptake of 65Zn. The agre...

A crucial topic for recreational drug research is the long-term effects of regular usage. With respect to cannabis, Solowij et al. (2002) noted: ‘One issue remains unresolved: does heavy, frequent or prolonged use of cannabis lead to a deterioration in cognitive function that persists well beyond any period of acute intoxication? Is the functioning of the brain altered in the long-term?’. Many ...

A number of antineoplastic drugs are used to combat with different types of cancer which have also shown to be mutagenic in various test systems. Various antineoplastic drugs such as cisplatin, cyclophosphamide, Tamoxifrn Genecitabine and Paclitaxel etc have shown to be clastogenic effects in various test systems (Garrone et al., 1993; Takeda et al., 2001; Padmalatha Rai and Vijaylakhmi, 2001; ...

Tetrazolium dyes have often been used as electron acceptors in measurements of cell proliferation rates (Berridge and Tan, 1993; Ishiyama, et al., 1993; Berridge, et al., 1996), in histochemical procedures (Zamudio, et al., 1969; May, et al., 1995b; Demehin, et al., 2001), and for assaying redox enzymes (Berridge and Tan, 1993; Mittler and Zilinskas, 1993; Debnam and Shearer, 1997; Ye, et al., ...

The complex series of molecular interactions between male and female gametes required for successful fertilization has captured the interest of several research groups for many years (Benoff 1997). Even though substantial insights into these interactions have been elucidated in particular in human and mouse (Fusi et al. 1992; 1996a; 1996b; Almeida et al. 1995; Evans et al. 1995; Bronson & Fusi ...

Three new species of the spider genus Philoponella Mello-Leitão, 1917 are described: Philoponella opelli n. sp. from Brazil and Ecuador, and Philoponella fluviidulcifis n. sp. , and Philoponella duopunctata n. sp. from Brazil. New records for Philoponella vittata (Keyserling, 1881), P. republicana (Simon, 1891), P. fasciata (Mello-Leitão, 1917) and P. divisa Opell, 1979 are provided for Brazil ...
