quote:His theory is supported by results from several animal models. For example it is shown that Trichinella spiralis causes inflammation in the motorneurons in rat, and that you can see morphological changes after infection by T. Spiralis. To be able to examine the myenteric plexa you have to take full thickness jejuno biopsies. In a study there was full thickness jejuno biopsies taken from patients with severe IBS. Of ten patients nine had inflammatory neuropathy. For example neuron degeneration was shown in seven patients.
