New intestinal disease charted by Swedish researcher

26.01.2004


Microscopic colitis is a newly discovered inflammatory intestinal disease that occurs in two different forms, lymphocytary colitis and collagenic colitis. Örebro University, Sweden, is on the cutting edge of research on these diseases, and Martin Olesen is one of first scientists in the country to write a dissertation on the subject, defending it at University Hospital, Örebro.



The disease is difficult to discover because the mucous lining of the intestine often looks perfectly normal when the colon is examined by so-called colonoscopy. But with the aid of tissue samples and microscopic analyses, rebro researchers have nevertheless succeeded in charting the extent of the disease.

Our study of new cases of microscopic colitis showed that the condition is considerably more common than was previously believed, says Martin Olesen. Microscopic colitis occurred in ten percent of all those undergoing a colonoscopy indicated by diarrhea and in twenty percent of those who were over 70 years of age. This means that microscopic colitis is just as common as the established intestinal disease ulcerous colitis.


The causes of lymphocytary colitis are probably numerous. In one tenth of patients it is suspected that the disease was caused by some drug set in as treatment for some other disease. There are also signs that it is an infectious disease and that heredity plays a role.

We found an increased production of nitric oxide in the intestine in both collagenic and lymphocytary colitis, says Martin Olesen. There also proved to be a correlation between the activity of the disease and the concentration of nitric oxide. One theory in this case is that drugs that reduce the production of nitric oxide in the intestines could help patients with microscopic colitis.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
