Vandellia cordifolia (V. cordifolia) used for treatment inflammation in traditional Chinese medicine was selected for immunopharmacological activity test. The effects of V. cordifolia extracted fractions on human mononuclear cells (HMNC) proliferation were determined by tritiated thymidine uptake. The results indicated that VC-ME fraction suppressed HMNC proliferation activated with phytohemagglutinin (PHA) and stimulated cell cycle progression was arrested at the G0/G1 stage. The inhibitory mechanisms may involve the blocking of interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) production, since VC-ME suppressed IL-2 and IFN-gamma production of HMNC in a dose-dependent manner. Therefore, it is suggested that immunomodulatory agents are contained in V. cordifolia.
Our previous study showed that the algorithm using quantified aerial perspective could control subjective depth in stereoscopic still pictures. Being integrated with a motion-estimation technique, this algorithm can be applied to motion pictures. In this paper, details of the algorithm and results of subjective assessment will be presented and discussed. Motion Estimation Luminance Calculation Depth Estimation Contrast Analysis Frequency Analysis Modulation-amplitude Calculation Contrast Modulation L/R Pictures Input L/R Pictures Output Figure 3. Block diagram of the new image-processing algorithm for motion pictures. The algorithm consists of the six conventional and one additional motion-estimation blocks. SID 11 DIGEST • 909 61.1 / S.
