    Notes: Abstract Somatic embryogenesis was achieved in callus cultures dervied from 40-day-old semimature zygotic embryos ofDalbergia sissoo on semi-solid Murashige and Skoog (MS) salts and vitamins supplemented with 0.46–1.16 μM kinetin, 6.78–9.04 μM 2,4-dichlorophenoxy acetic acid (2,4-D) and 30 g/1 sucrose. Somatic embryos proliferated rapidly by secondary somatic embryogenesis after transfer to half-strength basal MS medium supplemented with 0.46-1.16 μM kinetin and 6.78–9.04 μM 2,4-D with 2% (w/v) sucrose. The light-green somatic embryos germinated on half-strength MS salts and vitamins supplemented with 0.5 mg/1 abscisic acid and 2% (w/v) sucrose. The developmental stages of somatic embryogenesis were studied by light and scanning electron microscopy.

    Notes: Abstract  Both 5-HT1A and 5-HT2A receptors have been implicated in modulating ethanol self-administration. A novel serotonergic compound, FG 5974, with combined 5-HT1A agonist/5-HT2A antagonist activities, has shown effects in decreasing ethanol consumption in two-bottle choice paradigms. In the present study, the effect of this compound on operant responding for ethanol (as well as water and a saccharin solution) was compared to compounds possessing the separate neuropharmacological effects of this drug (the 5-HT1A agonist, 8- OH-DPAT, and the 5-HT2A antagonist, amperozide). While all three serotonergic compounds decreased operant responding for ethanol, only FG 5974 had no effect on water and saccharin responding. These results suggest that combined 5HT1A agonist/5-HT2A antagonist activity provides a more selective effect on ethanol reinforcement than either neuropharmacological action alone. Therefore, further analysis of mixed serotonergic compounds in general, and FG 5974 in particular, is warranted as they offer potential treatments for alcoholism.
