Hashish smoking and T-lymphocytes
No full textTo investigate the effect of long term hashish use on T-lymphocytes we have measured the incorporation of14C-thymidine by peripheral blood lymphocytes, unstimulated and stimulated by phytohemagglutinin, as well as the proportion and number of E-rosettes in 12 healthy male chronic users of the drug before and after a smoking session, and in 15 control subjects. The results show that hashish smoking does not impair the response of lymphocytes to PHA, at least at the concentration of PHA used. Furthermore there is a possibility that among chronic users a hashish smoking session may have a slight stimulatory effect. © 1978 Springer-Verlag
Acetylcholinesterase activity after hashish smoking
No full textRecent evidence suggests that the psychoactive effects of Δ9THC might be directly related to cholinergic activity [1] One possible mechanism by which the main active constituent of hashish could have its effect is by affecting acetylcholinesterase (AChE) activity [2, 3] On the contrary, Moss and his co-workers [4] suggest that according to their experiments on rats, there is no physiologically important interaction between AChE and Δ9-THC. Since these results show that the direct effect of A9-THC on AChE is to some extent contradictory, we tried to make some new observations on human volunteers and especially on heavy hashish smokers. © 1981 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted
Simultaneous separation and identification of hashish constituents by coupled liquid chromatography mass spectrometry (HPLC-MS)
No full textThis paper reports the use of liquid chromatography for the separation and determination of the major cannabinoids extracted from hashish samples. The direct coupling to the mass spectrometer enables the selective identification both of neutral and acidic cannabinoids. The developed method does not require any preliminary derivatization and should, therefore, be of interest in forensic analysis for simple and unequivocal determination of hashish constituents
Butterflyfishes (Chaetodontidae) from Abu Hashish fringing reefs, Port Sudan, Red Sea
No full textUsing Reef Check Programme butterflyfishes of Abu Hashish fringing reefs were recorded during 2003 and 2013. The results showed that the numbers of species declined from nine to seven. Chi square test revealed that the number of butterflyfishes significantly decreased (p<0.00001). This reduction was attributed to continuous construction and anthropogenic actives Keywords: Butterflyfishes, Abu Hashish, Port Suda

Identification in hashish of tetrahydrocannabinol, cannabidiol and cannabinol analogues with a methyl side-chain
No full textAbstract
The cannabis constituents Δ1-tetrahydrocannabinol, cannabidiol and cannabinol are accompanied by their homologues with an n-propyl and with a methyl side-chain. The identification procedure by combined gas chromatography-mass spectrometry in hashish and marihuana is described and the consequences for cannabis use are discussed.</jats:p
Ecstasy, cocaina ed hashish nelle rappresentazioni dei giovani.
No full textLa ricerca indaga il modo in cui gli adolescenti si rappresentano tre tipi di sostanze psicoattive (ecstasy, cocaina e hashish), le funzioni che queste possono esercitare nel fronteggiare le difficoltà che si associano al superamento dei compiti di sviluppo. E’ stato somministrato un questionario a 805 giovani e adolescenti costruito allo scopo di individuare il campo di riferimento comune delle tre rappresentazioni, la sua articolazione in relazione alla diversa implicazione nel consumo e i mo-di attraverso i quali i bisogni soggiacenti al ricorso alle droghe concorrono a rafforzare il Sé e l’identità nelle situazioni sociali.I risultati mostrano l’emergere di rappresentazioni specifiche e differenziate per ogni sostanza target anche se presentano alcune sovrapposizioni. L’hashish viene considerata per eccellenza la sostanza assunta da persone spericolate, impulsive, un po’ superficiali e irresponsabili al fine di apparire più in sintonia con il gruppo. La cocaina appare come una sostanza assunta soprattutto per migliorare le proprie prestazioni da individui solitari e centrati su di sé. L’ecstasy infine viene rappresentata come la droga della notte e della discoteca, in linea con quanto diffuso dai mass media. L’implicazione personale nel consumo appare un principio organizzatore dell’articolazione dei campi rappresentazionali soprattutto per quel che riguarda la concezione e le emozioni relative al consumatore, così come lo sono l’età dei rispondenti e la loro appartenenza di genere. Si conferma anche l’ipotizzato rapporto fra concezioni relative ai bisogni di rafforzamento del sé e ricorso a so-stanze psicoattive
