Opis:
Background. Arsenic is widely distributed in the environment. The main routes of absorption of inorganic arsenic compounds are the lungs and the gastrointestinal tract. Arsenates both (III) and (V) are absorbed from the gastrointestinal tract in 55-95%, while the organic arsenic compounds in 75-85%. Arsenic poisoning leads to damage the activities and morphological changes in the stomach and intestines, causing the occurrence of nausea, vomiting and diarrhoea. Arsenic compounds may also be the cause of the development of certain cancers (lung, skin and liver). The first changes caused by arsenic poisoning usually remain unnoticed. Arsenic affects haematological and both lipid and carbohydrate metabolism. It also causes changes in the organs involved in metabolism, so biochemical parameters or enzymes activity are therefore a good indicator of poisoning changes. Objective. The aim of this study was to examine the influence of protein and fat content in diet on selected biochemical blood parameters in rats. Materials and Methods. Rats (11 groups n = 88) were fed with 5 types of diet: control, low-protein, high-protein, low- fat and high-fat. Animals received water without arsenic (control group) or water with 10 or 20 μg As/mL. Results. In animals fed a low protein diets, regardless of the dose of arsenic, it was a decreasing of total cholesterol, triglycerides, and glucose in serum observed, compared to the control group. In the groups fed with low-protein diet revealed a significantly less damage in the liver as compared to the control group. In animals fed high-protein diets and with varying addition of arsenic a significant higher concentration of various biochemical parameters were found, in comparison to the respective control groups. In animals fed the high protein diet and poisoned with 20 μg As/mL of the arsenic significantly higher liver damage were found, compared to control group. Conclusions. Symptoms of arsenic hepatotoxicity measured with enzyme activity were highest in the groups of animals fed with low-protein diet. The parameters of lipid and carbohydrate metabolism depended mostly on diet than the dose of arsenic.
Wprowadzenie. Arsen jest pierwiastkiem szeroko rozpowszechnionym w środowisku człowieka. Głównymi drogami wchłaniania nieorganicznych związków arsenu są płuca oraz przewód pokarmowy. Arseniany (III) i arseniany (V) wchłaniają się z przewodu pokarmowego z wysoką wydajnością rzędu 55-95%. Organiczne związki arsenu ulegają wchłanianiu z przewodu pokarmowego z wydajnością 75-85%. Zatrucia związkami arsenu prowadzą do uszkodzenia czynności oraz zmian morfologicznych w żołądku i jelitach, powodują wystąpienie nudności, wymiotów i biegunki. Związki arsenu mogą być również przyczyną rozwoju nowotworów (płuc, skóry i wątroby). Cel. Celem badań była ocena wpływu zawartości białka i tłuszczu w diecie szczurów na wybrane parametry biochemiczne krwi szczurów zatruwanych arsenem. Materiał i metody. Szczury (11 grup samców n=88) karmiono 5 rodzajami diet: kontrolną, nisko- i wysokobiałkową oraz nisko- i wysokotłuszczową, oraz zatruwano arsenem w ilości 10 i 20 μg/ml. Wyniki. U szczurów karmionych dietami niskobiałkowymi, niezależnie od dawki arsenu, stwierdzono tendencję do obniżania się stężenia cholesterolu ogółem, triglicerydów i glukozy w surowicy krwi w porównaniu do grupy kontrolnej. W grupach oxazwierząt, które spożywały dietę niskobiałkową wykazano istotnie statystycznie mniejsze uszkodzenie wątroby w porównaniu do grup kontrolnych. U zwierząt karmionych dietami wysokobiałkowymi oraz z różnym dodatkiem arsenu stwierdzono istotne statystycznie wyższe stężenie poszczególnych parametrów biochemicznych w porównaniu do odpowiednich grup kontrolnych. U zwierząt karmionych dietą wysokobiałkową zatruwanych arsenem w ilości 20 μg/ml wykazano istotnie większe uszkodzenie wątroby w porównaniu z grupą kontrolną. Wnioski. Objawy hepatotoksyczności arsenu mierzone aktywnością enzymów były największe w grupie zwierząt karmionych dietą niskobiałkową. Na parametry gospodarki lipidowej i węglowodanowej większy wpływ miała zastosowana dieta niż dawka arsenu.

Opis:
The current methods of preventing calcium deficiency during the periparturient period are based primarily on a diet low in calcium and acidifying the rumen content before parturition, as well as on oral administration of liquid preparations or boluses. The available literature does not provide information on whether these forms of prevention are effective only immediately after the parturition, or whether they also affect an organism throughout the initial lactation period. The aim of the study was to examine the effects of three methods for the prevention of postpartum hypocalcaemia on selected indicators of mineral and energy metabolism, as well as on functional parameters of the parenchymal organs during the two week period following parturition in dairy cows diagnosed with low calcium concentrations before parturition, induced by a lower dietary mineral content. The study was conducted in 60 HF cows, aged 3-6 years old, fed TMR. The animals were divided into three groups: the first group received only a mineral preparation contained in the feed, adjusted to the physiological stage and milk production level; the second group received three additional doses (directly before the parturition, then 24 hours and 48 hours after the delivery) of an oral fluid preparation containing 62.5 g of Ca; while the third group received an intraruminal bolus containing 43 g of pure calcium (immediately after parturition). This research showed that physiological hypocalcaemia occurred at the beginning of lactation in the groups which had received additional calcium preparations (groups II and III), whereas in group I blood collection one week and two weeks after the parturition demonstrated subclinical hypocalcaemia. A statistically significant increase in magnesium and a decrease in phosphorus concentrations were also observed in the latter group, as well as an excessive GGTP activity and high bilirubin concentrations. Using only one complex mineral supplement in high yielding milk cows after parturition does not ensure the expected prophylactic effects, especially in the long term.

Opis:
In gilts, the period of early pregnancy occurring from the time of fertilization to the beginning of implantation is sensitive to any environmental disruptions, including an unbalanced diet of a future mother. Previously, we found that due to the undernutrition in gilts during this period, the endocrine intrauterine microenvironment and DNA methylation in the uterus have been changed. These distortions may diminish the success of pregnancy. In this study we focused on the influence of a restricted diet used in gilts during the first days of pregnancy on their biochemical and haematological parameters in peripheral blood. The applied restrictive diet vs. normal diet covered only 70% of the nutritional demands of early pregnant gilts. Normal (n = 4 gilts) or restrictive (n = 5 gilts) diets were used from the day of the first signs of the estrus until day 9 of pregnancy and biochemical and haematological parameters in blood plasma were determined during peri-implantation period, e.g. on days 15 to16 of pregnancy. In restrictive vs. normal fed gilts significantly lower plasma phosphorus, calcium and total cholesterol as well as the tendency to increasing concentrations of triglicerydes and asparate aminotranserase were found. Haematological parameters did not differ between the studied gilts. Thus, it seems that the availability of nutritional factors became suboptimal in restrictively fed early pregnant gilts. Even short-lasting undernutrition of females during the peri-conceptional period may cause a disruption of biochemical homeostasis during the peri-implantation period and probably affect the success of pregnancy.

Opis:
The effect of the Panax ginseng powder extract on reproduction, growth, renal and liver functions and some blood biochemical indices of Japanese quails were investigated. Panax ginseng powder extract at 2 mg and 4 mg/bird daily increased egg number per hen, average egg weight and hatchability. It slightly improved the efficiency of feed utilization and increased the levels of serum total protein, alkaline phosphatase and aspartate amino transferase (AST). The extract decreased significantly the levels of albumin, total lipids, triacylglycerols, cholesterol and glucose, and had no effect on body weight and the levels of serum bilirubin, urea and creatinine. This suggests that long term studies should be done on many different biochemical and physiological parameters and laboratory animals.
