Alpha 1-antichymotrypsin and IL-1 beta are not increased in CSF or serum in Alzheimer's disease.

Chronic inflammation associated with the amyloid plaques may represent an acute phase response in the brain. We quantitated the levels of two inflammatory markers; alpha 1-antichymotrypsin (alpha 1-ACT) and interleukin 1 beta (IL-1 beta) in paired serum and cerebrospinal fluid (CSF) samples from 40 patients with Alzheimer's disease (AD), 20 patients with Parkinson's disease (PD), and 42 age-matched controls. No differences in serum or CSF levels of either alpha 1-ACT or IL-1 beta were found between the groups. However, some AD patients had increased alpha 1-ACT index, suggesting an intrathecal production of alpha 1-ACT. Although alpha 1-ACT or IL-1 beta might be involved in the pathogenesis of AD, our results show that their measurement in serum or CSF is not valuable to support the clinical diagnosis of AD.

3D visualization library for multimodal medical images.

This study focuses on three-dimensional (3D) presentations of medical images such as magnetic resonance (MR) images and computed tomography (CT) images. Also multimodal presentations of medical images and signals, including different visualization techniques are considered. A C++ class library together with graphical user interfaces was developed for presenting the results. The implemented software operates in PC/Windows environment. It was tested with various medical images including raw MR and CT data and segmented images, and was applied in a hospital environment. The software operates relatively fast and the quality of resulting pictures is adequate for all tested medical applications. Further applications of 3D presentations in clinical medicine are considered.
