The role of saliva in maintaining oral health and homeostasis is based on its physicochemical properties and biological activities of its components, including salivary immunoglobulin A (IgA). Both salivary rates and immunological status of saliva are found to be compromised in smokers. The aim of this study was to investigate the acute time-dependent effect of smoking and black currant consumption on the salivary flow rate (SFR) and salivary IgA secretion rate (sIgA SR) in healthy smokers. SFR, sIgA levels in saliva, and sIgA SRs were determined in healthy smokers (n = 8) at eight times of assessment within three consecutive interventions: at the baseline; 5, 30, and 60 min after smoking; 5, 30, and 60 min after black currant consumption (100 g), followed by smoking; and 5 min after black currant consumption. Smoking induced a significant delayed effect on SFR measured 60 min after smoking (P = .03), while black currant consumption preceding smoking prevented that effect. Salivary IgA concentrations and sIgA flow rates were not acutely influenced by smoking. Black currant consumption preceding smoking induced a significant decrease in sIgA concentrations 5 min after the intervention compared with the baseline (P = .046), with a further increasing trend, statistically significant, 60 min after the intervention (P = .025). Although smoking cessation is the most important strategy in the prevention of chronic diseases, the obtained results suggest that the influence of black currant consumption on negative effects of tobacco smoke on salivary flow and immunological status of saliva could partly reduce the smoking-associated risk on oral health.

Berry fruits are a rich source of polyphenols, especially anthocyanins: well-known potent anti-oxidant phytochemicals. The purpose of this study was to evaluate beneficial effects of long-term consumption of polyphenol-rich organic chokeberry juice on different markers of antioxidant/pro-oxidant status in healthy female volunteers. Twenty-nine women, aged 25–49, were included in the study. Serological markers of oxidative stress and antioxidant defence, blood pressure, routine biochemical, and anthropometric parameters were analyzed at baseline and after twelve weeks of regular chokeberry juice consumption. Significant decrease in thiobarbituric acid-reactive substances level (TBARS; P < .001) and pro-oxidantantioxidant balance (PAB; P < .05), as well as increase in paroxonase-1 activity toward diazoxon (P < .01) were found. Total oxidative status and sulphydryl groups levels were not significantly influenced by the intervention. Anthropometric, biochemical parameters, and blood pressure values were within the referent values for all subjects and were not influenced by the chokeberry juice consumption. However, we found positive correlation between age, body mass index, waist circumference, body fat percent, blood pressure, and analyzed marker of lipid peroxidation, which was influenced by the consumption. In conclusion, the fine modulation of several antioxidant/pro-oxidant status biomarkers observed in healthy subjects indicates putative prophylactic effects of polyphenol-rich chokeberry juice and supports its importance as part of an optimal diet.

In recent times interest has increased in the complementary medicine of cancer patients. Two herbal mixtures were prepared from 17 and 12 plants, respectively. The goal of this study was to examine the in vitro cytotoxic and cell cycle effects of the aqueous-ethanol extracts (Extract 1 and Extract 2) obtained by maceration of the mixtures. The two extracts investigated exhibited significant antiproliferative activity toward two human breast cancer cell lines (MDA-MB-361 and MDA-MB-453) and a human cervix carcinoma cell line (HeLa) with 50% inhibitory concentration (IC50) values ranging from 9.92 to 17.38μL/mL. The extracts did not exert any significant cytotoxicity toward healthy human peripheral blood mononuclear cells. In vitro antitumor activites were accompanied by an important apoptotic fraction of all cell lines after treatment with the extracts. The amount of total phenols was similar in both extracts, whereas the concentration of total tannins was significantly higher in Extract 1. Extract 1 was also found to be a stronger free radical scavenger, with an IC50 value of 13.4μg/mL. Both extracts contained rosmarinic acid, while ursolic acid was identified in Extract 2.
