A study relates the neural damage provoked by Ecstasy with the ambient temperature at which it is consumed

06.08.2007
There exists a direct relationship between the consumption of MDMA, or Ecstasy, at a high ambient temperature and an increase in the neural damage which this drug provokes. This was the conclusion of the research carried out by Beatriz Goñi at the School of Pharmacy of the University of Navarra.

These results form part of her doctoral dissertation, entitled “A study of the neurotoxicity mechanism of 3.4-methylenedioxy-N-methylamphetamine (MDMA or ‘Ecstasy’) after its administration in rats: New responses to old questions.” By means of this study, the researcher was able to relate for the first time the body temperature of the user with a higher metabolism of this substance. There are two factors which, when they co-occurcan produce malignant hyperthermia, a disorder which can sometimes be fatal.

In order to come to this conclusion, the Pamplonan pharmaceutical specialist administered the drug to rats at ambient temperatures of 15, 21 and 30 degrees centigrade. After performing the pertinent analyses, she demonstrated that metabolism of Ecstasy is accelerated by higher ambient temperatures at the time of administration. In addition, higher ambient temperatures also increase, in the same proportion, the neurochemical deficit that affects the brains of the users of this drug.

Higher risk in closed establishments

According to Beatriz Goñi, the author of the study undertaken at the University of Navarra, the discoveries of this research project acquire more relevance precisely because Ecstasy is typically taken in closed environments, with lots of people and poor ventilation, due to which factors the temperature tends to be quite high.

In addition, she notes that the neural damage provoked by this substance, and which originally was only observed in rats, has already been demonstrated in humans, who appear to suffer severe damage to the serotoninergenic neurons, which are involved in processes as basic as sleep, appetite and mood regulation.

Finally, the pharmaceutical specialist noted that the damage caused by the consumption of MDMA is dependent upon its being metabolized after to its ingestion, since if it were administered directly to the brain, neuronal damage would not occur.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
