Background: Mindfulness-based cognitive therapy (MBCT) has been widely used to treat patients with depressive disorder to prevent relapse. The objective of this study was to examine the effectiveness of newly developed MBCT program as an adjuvant to pharmacotherapy in the treatment of patients with panic disorder or generalized anxiety disorder., Methods: Forty-six patients with panic disorder or generalized anxiety disorder were assigned to either MBCT or an anxiety disorder education (ADE) program for a period of 8 weeks. The Hamilton Anxiety Rating Scale (HAM-A), Hamilton Depression Rating Scale (HAM-D), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Symptom Checklist-90-Revised (SCL-90-R) were used to assess the patients at 0 week and after the two programs had been running for 2, 4, and 8 weeks., Results: The MBCT group demonstrated significantly more improvement than the ADE group according to all anxiety (HAM-A, p<0.01; BAI, p<0.01; anxiety subscale of SCL-90-R, p=0.01) and depression (HAM-D, p<0.01; BDI, p<0.01; depression subscale of SCL-90-R, p<0.01) scale scores. The obsessive-compulsive and phobic subscales of the SCL-90-R also showed significantly more improvement in the MBCT group. However, no significant improvement was observed in the MBCT group versus the ADE group in terms of the somatization, interpersonal sensitivity, paranoid ideation, or psychoticism subscale scores of the SCL-90-R., Conclusions: MBCT may be effective at relieving anxiety and depressive symptoms in patients with panic disorder or generalized anxiety disorder. However, well-designed, randomized controlled trials are needed.

A simple and reliable method for quantifying the fluid content and characterizing the tissue T2 relaxation properties of animal extremities has been devised. This one-dimensional magnetic resonance imaging experiment, applied to the adjuvant arthritis model in rats, provides a useful, noninvasive monitor of the course of the disease in vivo. Tissue is characterized through the analysis of the biexponential T2 decay of the NMR-active hydrogen in the rat leg joint tissue. Long and short T2 components are identified, both of which are sensitive to the arthritic process. The long component is suggested to come from edema and increases by a factor of ca. 9 during the course of the disease, whereas the short T2 component may represent cellular influx into the joint and increases by a factor of ca. 3. These changes correlate with the severity of the disease and can be used to monitor therapeutic response. The main advantage of the technique over the more traditional two-dimensional imaging approach is that only one spatial variable has to be resolved, resulting in shorter imaging time.
