GLOBULAR RESISTANCE MODIFICATION ON RATS CONSECUTIVELY TO Al2(SO4)3 ADDITION FOR TWO GENERATION

Some of the major modifications on membranes produced by the oxygen reactivespecies are membranal structure and functions modifications, lipids peroxydation,membranal protein alterations and transportation disturbances thru membranes.A series of xenobotics like oxidant pollutants, lead, aluminium and others directlyor indirectly are producing thru metabolization free radicals which interact withcells components and alterate their functions. The purpose of this paper was torelieve the impact of aluminium cumulative addition onto globular resistance onrats. Has been administrated three levels of aluminium (200ppb, 400 ppb şi 1000ppb) as Al2(SO4)3 ad libidum in water. Was followed their toxicity impact on theglobular resistance for two generations. The results indicate a decrease ofglobular resistance directly correlated with the aluminium addition

Cadmium level in some tissues and organs from wild boar

The wild boar (Sus scrofa) is one of the most common species of Romanian wild game. It’s meat is found often on the market and in peoples menu list. One of the most dangerous heavy metals is cadmium. It has several toxic effects on: kidneys, liver, testes, bones [2, 5]. The study was carried out in three different areas regarding the contamination level with heavy metals: Forest District M., Forest District. C and Forest District S. Cadmium concentration was directly correlated with the pollution degree of the three different areas Forest District M. >Forest District C.> Forest District T. Cadmium concentration in wild boar tissues and organs was: in Forest District C. between 0.009 ppm and 0.341 ppm; in Forest District M. between 0.011 ppm and 5.346 ppm and in Forest District T. between 0.007 ppm and 0.123 ppm

Acid-base status broiler fed with different levels of BY-ethanol plant (DDGS) in feed mixtures

Provedenim istraživanjem htjeli smo dokazati utječu li različite koncentracije DDGS-a u krmnoj smjesi na pokazatelje acidobaznog statusa u krvi kod tovnih pilića. DDGS je nusproizvod proizvodnje etanola, a karakterizira ga značajan izvor aminokiselina, energije i fosfora u hranidbi peradi. Održavanju acidobazne ravnoteže unutar fizioloških granica u organizmu životinje ključnu ulogu imaju krvožilni i respiratorni sustav. Provedeni pokus se sastojao od tri skupine tovnih pilića hibrida Cobb 500 po 40 tovnih pilića po skupini. Pokus je trajao 42 dana. Kontrolna skupina (K) bila je bez DDGS-a, pokusnoj skupini (P1) dodano je 15 % DDGS-a i pokusnoj skupini (P2) 25 % DDGS-a u smjesu. Ovim istraživanjem utvrđeni su parametri acidobazne ravnoteže u krvi tovnih pilića te su izračunom dobivene vrijednosti anionskog procjepa (AG) i razlike jakih iona (SID) u kontrolnoj i obje pokusne skupine. Jedino je pCO2 vrijednost kontrolne skupine pokazala statistički značajnu manju vrijednost (P<0,05) u odnosu na drugu pokusnu skupinu (P2), ostali parametri nisu pokazali statistički značajna odstupanja. Izračunom vrijednosti anionskog procjepa i razlike jakih iona kontrolna skupina je imala manje vrijednosti no obje pokusne skupine. Tovni pilići su 10 dana nakon uzimanja krvi žrtvovani. Tokom života tovni pilići nisu pokazivali nikakve znakove narušenog zdravstvenog stanja, navedena odstupanja se mogu pojaviti uslijed stresa te proljevaThe research which was conducted aimed at showing whether the different concentration of DDGS in broiler feed affects acido - base balance. DDGS is a byproduct of ethanol production, and it is a significant source of amino acids, energy, and phosphorus, which are important in poultry feed. In preservation of acid balance within the physiological range circulatory and respiratory system have a crucial role. The experiment included three groups of 40 hybrid broiler chicks Cobb 500. The research lasted for 42 days. The control group (K) was without DDGS, experiment group (P1) was added 15%, and the second experiment group (P2) was added 25% DDGS in the mixture. With this reasearch we gathered information about acido-base balance in the broilers blood and the calculation values obtained anion gap (AG) and the strong ion difference (SID) in the control and both experimental groups. Only pCO2 values of the control group showed a lower value (P <0.05) compared to the second experimental group (P2), other parameters did not show statistically significant deviation. The calculation of the value of anion gap and difference of strong ions, control group had a significantly lower value than either of experimental groups. Broilers were 10 days after the blood was taken sacrificed. Broiler did not show that there's a damaged health during their life time. Indicated deviations may occur due to stress and diarrhea

Aronia Melanocarpa Antioxidant Potential against Chromium VI Induced Morphological Changes in Endocrine Pancreas

AbstractHexavalent chromium is known as strong oxidizing agent, enters the cells easily and generates reactive oxygen species. It was demonstrated that Cr VI is toxic for liver, kidney, skin, nervous system, female and male reproductive systems. However, chromium effects on pancreas are less studied.Aronia melanocarpa fruits are rich in phenolic constituents: anthocyanins, procyanidins and phenolic acids, which demonstrated to have anti-oxidative, anti-viral, anti-mutagenic, anti-cancer, anti-inflammatory activities.Considering the aforesaid the present study was carried out in idea to see if Cr VI induces structural changes in pancreas, given it’s property of inducing ROS formation in cells, and if aronia extract can play a protective role.The study was carried out on white Wistar rats divided in 5 groups and exposed as follows: C - control -distilled water, Cr group - potassium dichromate, hexavalent chromium compound, in distilled water, 75 ppm for three months; CrA group - 75 ppm Cr VI + extract of A. melanocarpa for three months; Cr2 group - 75 ppm Cr VI for three months followed by one month of distilled water; CrA2 group 75 ppm Cr VI for three months followed by one month of extract of A. melanocarpa. At the end of exposure period pancreas was collected and prepared for histological analysis.Hexavalent chromium administration induced morphological and functional changes in endocrine pancreas cells. Microscopic examination of histological slides from pancreas revealed the size and number reduction of Langerhans islets and presence of degenerative lesions. Experimental group that received Cr VI combined with aqueous extract of Aronia presented almost normal architecture of endocrine cells, even more vascular changes occurred too, probably responsible for repairing phenomena

Lead levels in soil-water-plant chain from a foresty ecosystem

Lead level was determined in soil (20 cm and 40 cm deep), water (water sources for wild game) and plants from three Forest Districts placed in areas with different degree of pollution. Determination of lead concentration was made in forestry ecosystem to see the impact of heavy metals (lead) on wildlife. In soil lead concentration was in limits at both depths (20cm and 40 cm) for all three Forest Districts, in water samples lead level exceeded the maximum admitted limit for drinking water (0.01 ppm) and for surface water (0.01 ppm) and from ecological point of view were in the Vth quality class. Lead concentration was under the maximum admitted limits for plants in all three Forest Districts

Some aspects regarding the traceability of food products

The traceability of food products is of major interest for ensuring the composition quality and protecting the consumers. The improvement of traceability control methods is based on preliminary stages of checking the purity of the component ingredients, technologies / biotechnologies for which analytical, bioanalytical and biophysical methods are used. A brief presentation of the specific methods for traceability control is presented in this paper
