In living organisms lead is classified as potential toxic metal, and in high concentration can produce intoxication with the alteration of some vital organs, especially liver and kidney. In aquatic environment lead can be absorbed by fishes and other organisms, with different distribution in various tissues. Our aim of experiment was to verify and demonstrate the protective effect of lyophilized garlic and chlorella against bioaccumulation of lead in fishes living in aquatic environment deliberated polluted with lead. Thus, lyophilized garlic and chlorella administrated as supplements in fodder for fishes (Carassius gibelio) diminished the antagonistic effect of lead against zinc in all tested tissues: liver, kidney, heart, brain, ovary, testis, muscles myotome � epaxial, skin � with scales, gills, and intestine.

Toxic Potential

Living organisms take nutrients from the environment, and together with them, substances with toxic potential � such as heavy metals. Lead is one common metal pollutant especially in aquatic environment, from where the fish can be intoxicated very easily. Bioavailability, distribution, toxic action, synergistic and antagonistic effects are characteristics which can alter the fish health. Our experimental study followed the effects of lead overload in water on iron distribution, in different tissues sample Carassius gibelio Bloch fish. We performed the experiment in four different fish groups: control C; lead � Pb (administration of lead in water 0.075mg/mL of water, as Pb(NO3)2 x � H2O); lead (the same dose) and 2% of freeze-dry garlic incorporated into fishes� food � Pb+garlic; lead (the same dose) and 2% chlorella incorporated into fishes� food � Pb+chlorella, for 21 consecutive days. The iron concentration was analysed with AAS (Atomic Absorption Spectroscopy) from gills, muscle, skin (and scales), intestine, liver, heart, brain, ovary, testicles, and kidney. The obtained data presented a significantly decrease of iron content in all tested tissue samples that demonstrated, alteration of iron homeostasis, explained by a strong antagonistic effect of lead on iron. Our experiment showed that biologic active principles from garlic and chlorella act like natural protectors, and potentiate the iron deficiency even in the case of lead overload in aquatic environment, for fish.

Carassius Gibelio

Minerals are involved in the most metabolic pathways and are necessary for living organisms in different concentrations. When the concentration of these biominerals is unbalanced due to different factors, the metabolic processes are disturbed and the organism tries to find recovery solutions. Cu is one mineral indispensable for living organism, also for fishes, and its concentration it could be drastically reduced by the presence of high concentration of some heavy metals � like Pb, due to antagonistic effect. Our research evaluates the Pb toxic potential on Carassius gibelio Bloch on Cu distribution in different tissues and two natural solutions for potentiation of antagonistic effect of Pb on Cu. We worked on four different fish groups: control group (C); and for three experimental groups we add 75 ppm Pb � as Pb(NO3)2 x �H2O into the water from aquarium. To potent the Pb toxicity we add into the grounded fish feed 2% lyophilized garlic to E3 group and 2% chlorella to E4 group. Every group had 30 fishes in separate aquarium, the fishes were fed every 2 times a day and had 12h alternate light and dark. After 21 days of experiment the fishes were euthanized with cloves oil and the tissue samples were collected (brain, gill, gonads, intestine, kidney, liver, striated muscle � epaxial myotomes, cardiac muscle, and skin). The samples were analytical prepared for AAS in order to determinate the Cu concentration in all tissue samples. The results presented the best protection of garlic against antagonistic effect of Pb on Cu in brain and testicles, and the lowest protection in muscle-striatal; while chlorella best protection was observed in heart muscle, brain, kidney and liver, and lowest protection in muscle-striatal.

Mercuric Mercury

This paper reviews the growing literature dealing with the antagonistic effect of selenium (Se) compounds on the toxicity of mercury (Hg) compounds in higher animals and organisms present in the aquatic environment. It covers both laboratory and field studies and summarizes the possible mechanisms that explain the protective action of Se compounds on mercuric mercury (Hg2+) and methylmercury (CH3Hg+) toxicity. The review is subdivided according to the molecular form of Hg and the organisms in which the antagonism has been studied. Many authors suggest that the protective effect of selenite on the toxicity of Hg2+in mammals is due mainly to the in vivo formation of mercuric selenide (HgSe), a stable and biologically inert complex. The detection of HgSe has been confirmed in several studies in support of this mechanism. Possible mechanisms that may be involved in the antagonism between Se compounds and CH3Hg+in mammals and aquatic organisms are also presented. The possibility of adding Se compounds to contaminated lakes and reservoirs as a remediation technique to limit the bioaccumulation of Hg2+and CH3Hg+is critically discussed.

Chromium (Cr) is recognized as a toxic metal that has detrimental effects on living organisms; notably, it is discharged into soil by various industries as a result of anthropogenic activities. Microbe-assisted phytoremediation is one of the most emergent and environmentally friendly methods used for the detoxification of pollutants. In this study, the alleviative role of Staphylococcus aureus strain K1 was evaluated in wheat (Triticum aestivum L.) under Cr stress. For this, various Cr concentrations (0, 25, 50 and 100 mg·kg−1) with and without peat-moss-based bacterial inoculum were applied in the soil. Results depicted that Cr stress reduced the plants’ growth by causing oxidative stress in the absence of S. aureus K1 inoculation. However, the application of S. aureus K1 regulated the plants’ growth and antioxidant enzymatic activities by reducing oxidative stress and Cr toxicity through conversion of Cr6+ to Cr3+. The Cr6+ uptake by wheat was significantly reduced in the S. aureus K1 inoculated plants. It can be concluded that the application of S. aureus K1 could be an effective approach to alleviate the Cr toxicity in wheat and probably in other cereals grown under Cr stress.

Apple contains high concentration of phenolic compounds that protect cells from oxidative stress. The prolong exposure of free radicals may induce cell damage and premature cell aging. Both local and imported apple contain flavonoid, saponin, tannin, steroid, and terpenoid. The extract of local and imported apples showed low toxicity on NIH3T3 fibroblast cells, with IC50 value of 529 and 463 µg/mL, respectively. Both apple extracts (50 – 250 µg /mL) protected three-day-H2O2 induced-cell damage and cell death. Protective effect was observed as the viability increase of treated cells compared to untreated ones. The protective effect of both extracts were higher than the effect of vitamin C as standard antioxidant at this study. Both apple extracts could reverse cell damage caused by three-hour-high concentration H2O2 exposure, similar with vitamin C. Low concentration of both extracts (50 µg /mL) induced the increase of fibroblast cells’ proliferation kinetics. The extract of imported apple showed higher properties of protective, cell recovery and proliferation of fibroblast cells tha local apple, but not statistically significance. This study concludes that the extract of local and imported apples have high potency in cytoprotective effect and cell recovery of damaged cells caused by free radicals induction. Both apple extracts have high potency to be developed the candidate of antiaging and cells’ regeneration agent.Key words: antiaging, cell recovery, cytoprotective, NIH3T3 cells
