The study discusses Arab religious beliefs and rites, which were filled with mythical elements such as idol worship, treating some animals as sacred, and worship of the sun, plants, certain inanimate objects and birds. It describes the various stages through which these beliefs passed, from sanctification of trees and caves, through the worship of the sun and the stars, to idol worship and more. The study then proceeds to inquire into the traces of mythology to be found in Arabic poetry. It shows how humans did not only inherit their forefathers＇ beliefs, but also their ideas, and explains how poets were able to embody reality by means of artistic symbols that reflected such elements of their lives as emotions and objective mental states. Subsequently the study discusses the sanctity which the Arabs ascribed to some animals, and which they worshipped in the hope of obtaining a blessing, maintaining an intimacy with the animal or averting evil. Many Arabs in those days believed in the sanctity of animals, the sun, the moon and Venus, thought that trees and other p｜ants possessed a spirit, and considered some animals to be deities with extraordinary powers, among them the viper, the crocodile, the bull, the gazelle and the goat. Finally, the study shows how pre-lslamic Arabic poetry can serve as a reliable document that reflects the society of the times, and how even the restricted amount of verse that has survived from those times can provide considerable information about mythical elements that go back to the remotest times.展开更多
The effects of clinically relevant doses of commonly prescribed stimulants methylphenidate （MPH）, d-am- phetamine （d-AMPH）, and dl-AMPH or mixed amphetamine salts （MAS） such as Adderall, on short- and long-term ...The effects of clinically relevant doses of commonly prescribed stimulants methylphenidate （MPH）, d-am- phetamine （d-AMPH）, and dl-AMPH or mixed amphetamine salts （MAS） such as Adderall, on short- and long-term gene neuroadaptations in developing animals have not been widely investigated. In the present review, the effects of oral stimulant administration were compared with those of the subcutaneous or intra-peritoneal route. A selective set of stud- ies between 1979 and 2010, which incorporated in their design developmental period, clinically relevant doses of stimu- lants, and repeated daily doses were reviewed. These studies indicate that neuroadaptation to chronic stimulants includes blunting of stimulated immediate early gene expression, sensitivity of younger （prepubertal） brain to smaller dosages of stimulants, and the persistence of some effects, especially behavioral neuroadaptations, into adulthood. In addition, oral amphetamines （MAS） have more profound effects than does oral MPH. Further animal developmental studies are required to understand potential long-term neuroadaptations to low, daily oral doses of stimulants. Implications for clinical practice were also discussed.展开更多
