Stress, hormones, and UN soldiers

22.02.2002


It is possible to measure levels of the stress hormone cortisol not only in blood but also in saliva. Linköping physician Elisabeth Aardal-Eriksson has further developed a saliva test to make it reliable and easy to use, not only in hospitals but also in the field. The findings are presented in a dissertation at Linköping University, Sweden. The researcher has also found that the corisol content of saliva is related to the occurrence of so-called posttraumatic symptoms of stress.



In the first section of her dissertation, Elisabeth Aardal-Eriksson has developed the method for measuring, tested it in connection with a standardized loading of the stress system, and, in a smaller study, combined it with psychological self-assessment (in which the person being tested provides his/her own information about how he/she feels). This self-assessment also included questions about possible posttraumatic symptoms such as nightmares and painful memories.

The second section of the thesis consists of two studies of Swedish UN soldiers who have served in Bosnia. In one of these studies cortisol and stress levels were metered both before and at different times after their tour of duty in Bosnia. In another study cortisol levels and stress reactions were investigated in a group of UN soldiers involved in a landmine accident in Lebanon.


The before/after study showed that there is a correlation between the hormone levels of a UN soldier prior to serving in Bosnia and how bad they felt afterward.

“Those who had a high degree of post-traumatic symptoms often had lower cortisol levels in the initial tests. This can be interpreted as meaning that they were less able to load their stress system when confronted by difficult situations,” says Elisabeth Aardal-Eriksson.

Cortisol tests alone are not sufficient today to assess a person’s ability to cope with stress, she points out. Factors like family conditions, work situation, genetic make-up, and earlier life experience also influence who can cope with extremely difficult conditions and who cannot. But measuring cortisol in saliva can be one of several ways to clinically assess patients with post-traumatic stress.

Saliva samples could also replace blood samples when it comes to measuring hormone levels in connection with hormonal diseases. This would be of great value, not least for children, severely ill patients, and people who are afraid of giving blood samples.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
