Figure 4. Antioxidant capacity and lipid oxidation in plasma of volunteers consuming different amounts of procyanidin-rich dark chocolate (6.9 mg of procyanidins per g of chocolate). Antioxidant capacity was evaluated by the ability of plasma to inhibit luminol-dependent chemiluminescence and lipid oxidation by plasma TEARS. Plasma epicatechin concentrations are the average amount of epicatechin determined two hours after chocolate consumption. Ordinate values indicate increases over basal levels of plasma antioxidant capacity (white bars), or decrease over basal values for TEARS (gray bars).

Kinetic analysis of luminol-dependent chemiluminescence demonstrated that a solution of berbamine (20 pM) was found to inhibit the generation of various types of reactive oxygens by guinea-pig neutrophils. The results of these and other experiments suggest that berbamine inhibits the active oxygen generation via the stabilization of plasma membrane and the inhibition of phospholipid-dependent protein kinase (PKC) and NADPH oxidase activation [178]. 

The analysis of the discriminating functions clearly indicates that while the lucigenin-dependent CL parameters do not generate any statistically significant discriminating functions, the luminol-dependent parameters, mainly those in presence of zymosan, generate two statistically significant functions. 

Because the discriminant analysis seems to indicate that anaesthesia is able to induce a modification of luminol-dependent CL in presence of zymosan without any modification of lucigenin-dependent CL, we compared the luminol-dependent zymosan-stimulated CL (LumZI) with the lucigenin-dependent resting CL (LucBI) measured at different time intervals from anaesthesia (Figure la time<2 h Figure lb time>2 h). A clear change of the slope of the regression line is obtained.

The results presented in this article are the continuation of our studies of side effects of phenothiazines.3 These neuroleptics are known for their numerous desired and also undesired side effects. Our investigations were carried out mainly using luminol-dependent CL in reactive oxygen species (ROS)-containing systems, both in the presence and in the absence of cells. ... 

Luminol-dependent CL we detected with a CL LKB 1251 luminometer (Bioorbit, Turku, Finland) connected to a PC via serial interface, and MultiUse program ver. 1.08 (BioOrbit) was used to collect data.
