Cím:Orally delivered sour cherry seed extract (SCSE) affects cardiovascular and hematological parameters in humans / Zoltan Csiki, Agnes Papp-Bata, Attila Czompa, Aniko Nagy, Istvan Bak, Istvan Lekli, Andras Javor, David D. Haines, Gyorgy Balla, Arpad Tosaki

Megjegyzések:In the present study, we investigated the effects of sour cherry seed extract (SCSE) on a variety of systemic processes that contribute to general health and viability of human subjects. The experiments were conducted according to a double-blind protocol in which six healthy individuals were administered 250-mg/day SCSE for 14 days, while four were treated with placebo. Peripheral blood was collected before and after the treatment period. Samples were analyzed for levels of selected cells, enzymes, or metabolites. Subjects that received SCSE showed increases in the values of mean cell volume, serum transferrin, mean peroxidase index, and representation of peripheral blood lymphocytes. On the other hand, decreases were observed in circulating neutrophils and ferritin levels. Changes observed in the present study do not fit into a clear pattern that might yield additional in-depth understanding of SCSE-mediated alterations in physiologic responses. The most encouraging result of the present study is the absence of any indication of toxicity by subjects consuming the extract.

Cím:Aged (Black) versus Raw Garlic against Ischemia/Reperfusion-Induced Cardiac Complications / Attila Czompa, Kitti Szoke, Jozsef Prokisch, Alexandra Gyongyosi, Istvan Bak, Gyorgy Balla, Arpad Tosaki, Istvan Lekli

Megjegyzések:Background: Recent evidence of studies suggests that aged black garlic also has health beneficial effect. The major aim of the present study is to compare the effect of raw and aged black garlic on postischemic cardiac recovery. Methods: Male Sprague Dawley rats were randomly divided into three groups. Animals of the first group were fed with raw garlic, animals of the second group received aged black garlic, while the third group served as vehicle treated control. At the end of the treatment, isolated hearts were undertaken to ischemia/reperfusion. Heart function and infarct size were measured and the level of HO-1 and iNOS were studied. Results: We have found superior postichemic cardiac function and reduced infarct size in both garlic treated groups compared to the drug-free control group, indicating cardioprotective effects. However, no significant differences between the garlic treated groups were observed. Our Western blot analysis revealed that raw garlic enhanced the level of HO-1 before ischemia, while in ischemic samples we found elevated HO-1 expression in both garlic treated groups. The level of iNOS was the same before ischemia in all groups, however, a markedly reduced iNOS level in ischemic/reperfused hearts originated from control and raw garlic treated animals was observed. In samples from aged black garlic treated animals, the level of iNOS was not significantly reduced after ischemia/reperfusion.Conclusion: Taken together our results indicate that not only raw but also aged black garlic also possesses cardioprotective effect.

Cím:The Cellular Autophagy Markers Beclin-1 and LC3B-II are Increased during Reperfusion in Fibrillated Mouse Hearts / Gregory Meyer, Attila Czompa, Cyril Reboul, Evelin Csepanyi, Andras Czegledi, Istvan Bak, Gyorgy Balla, Jozsef Balla, Arpad Tosaki, Istvan Lekli

Megjegyzések:Autophagy is an intracellular bulk degradation process for elimination of damaged macromolecules and organelles. In the past decades, the scientific community has gained increasingly detailed understanding of the role of autophagy in myocardial homeostasis, although still many controversies remain. In the ischemic myocardium, autophagy appears to be beneficial for survival, whereas upon reperfusion the process may induce cell death. However, the overall effect of autophagy seems to depend on the duration and intensity of stress, as along with the extent of autophagy within myocardial tissue. Reperfusion of an ischemic heart maybe harmful, but it is an essential process for myocardial survival. One of the major adverse consequences of reperfusion is the occurrence of ventricular fibrillation (VF). In the present study, we investigated the possible connection between autophagy and VF. Isolated mouse hearts were subjected to ischemia/reperfusion (I/R) and divided into two groups based on the development of VF at the beginning of reperfusion. Western blot analysis was conducted for autophagy-associated proteins LC3B, ATG-5, ATG-7, ATG-12, Bcl-2 and Beclin-1 proteins. Significantly higher level of Beclin-1 and LC3B-II/LC3B-I ratio (both definitive autophagy biomarkers) was observed in the fibrillated myocardium, versus tissue from the nonfibrillated hearts. Interestingly, although Bcl-2 is a major regulator of Beclin-1, level of this protein was not significantly altered in tissue from fibrillated, versus non-fibrillated hearts. Moreover, Atg7 expression showed a trend, albeit non-significant, towards elevation in fibrillated versus non-fibrillated hearts. Results of the present investigation demonstrate a possible link between VF and autophagy. Studies by authors of this report to evaluate potential etiologic relationships between the two processes are ongoing.

Cím:Cardiovascular effects of low versus high-dose beta-carotene in a rat model / Evelin Csepanyi, Attila Czompa, David Haines, Istvan Lekli, Edina Bakondi, Gyorgy Balla, Arpad Tosaki, Istvan Bak

Megjegyzések:?-carotene (BC), a lipid-soluble tetraterpene precursor to vitamin A, widely distributed in plants, including many used in human diet, has well-known health-enhancing properties, including reducing risk of and treatment for certain diseases. Nevertheless, BC may also act to promote disease through the activity of BC derivatives that form in the presence of external toxicants such as cigarette smoke and endogenously-produced reactive oxygen species. The present investigation evaluates the dose-dependent cardioprotective and possibly harmful properties of BC in a rat model. Adult male rats, were gavage-fed BC for 4 weeks, at dosages of either 0, 30 or 150 mg/kg/day. Then hearts excised from the animals were mounted in a "working heart" apparatus and subjected to 30 minutes of global ischemia, followed by 120 minutes of reperfusion. A panel of cardiac functional evaluations was conducted on each heart. Infarct size and total antioxidant capacity of the myocardium were assessed. Heart tissue content of heme oxygenase-1 (HO-1) by Western blot analysis; and potential direct cytotoxic effects of BC by MTT assay were evaluated. Hearts taken from rats receiving 30 mg/kg/day BC exhibited significantly improved heart function at lower reperfusion times, but lost this protection at higher BC dosage and longer reperfusion times. Myocardial HO-1 content was significantly elevated dose-responsively to both BC dosage. Finally, in vitro evaluation of BC on H9c2 cells showed that the agent significantly improved vitality of these cells in a dose range of 2.5-10 ?M.Although data presented here do not allow for a comprehensive mechanistic explanation for reduced cardioprotection at high dose BC, it is speculated that since Fe2+ produced as a metabolite of HO-1 activity, may determine whether BC acts as an antioxidant or prooxidant agent, the strong induction of this enzyme in response to ischemia/reperfusion-induced oxidative stress may account for the high-dose BC loss of cardioprotection.
