Analysis of forensic samples of "Ecstasy" tablets seized in Novi Sad during the 2004 year

The paper presents results of the analysis of illicit synthetic drugs in the form of tablets distributed under the name "Ecstasy", seized by the police in the broader area of Novi Sad 2004. A huge number of tablets has been analyzed (n=121), of various colours and with impressed symbols from the total amount of 93 seizures, which totally amounted to 1458 tablets. Regarding the number of seizures ecstasy (3,4-methylendioxy-N-meth-yl-amphetamine - MDMA) is dominant among all, and according to the quantity of seized tablets it is amphetamine (AP), while other amphetamine-type drugs (methamphetamine MA 3,4-methylendioxiamphetamine - MDA, 3,4-methylendioxi-N-ethyl-amphetamine MDEA) have been found in rather small quantities and very rarely. Tablets mostly contain caffeine as an additive. In the analytical procedure, the samples of tablets were subjected to liquid-liquid extraction and afterwards analyzed on the GCD (GC-EI) Hewlett-Packard instrument. The method is fast reliable and reproducible for the analysis of amphetamine, methamphetamine MDA, MDMA, MDEA, as well as various additives in the samples of seized tablets

Uticaj farmakološki aktivnih jedinjenja iz ekstrakta Ginkgo bilobae na kontraktilnost duodenuma i ileuma kunića

Findings that there are pharmacologically active compounds in the Ginkgo bilobae extract recently provoked numerous investigations of their action on the receptors of the autonomous nervous system. The purpose of the present study was to determine the influence of gingko extract on the contractility of the longitudinal smooth muscle layer in the wall of the rabbit duodenum and ileum using the method of Magnus. Results clearly show that gingko extract causes a dose dependent tonus decrease of duodenal and Heal smooth muscles in the rabbit. It also reduces the stimulation of spontaneous activity of smooth muscles caused by acetylcholine, the reduction being greater in ileum compared to duodenum.Biohemijska saznanja o prisustvu farmakološki aktivnih jedinjenja iz ekstrakta Ginkgo bilobae, dala su nov podstrek za izučavanje njihovog dejstva na receptore autonomnog nervnog sistema. Otuda je cilj našeg istraživanja bio da se ispita uticaj ekstrakta ove biljke na kontraktilnost glatkomišićnog sloja u zidu duodenuma i ileuma kunića metodom po Magnus-u. Rezultati Istraživanja ukazuju da ispitivani ekstrakt izaziva dozno-zavisno sniženje tonusa longitudinalne glatke muskulature duodenuma i ileuma, kao i da redukuje acetilholinom izazvanu stimulaciju spontane aktivnosti duodenuma i ileuma
