Abstract

An effect of the exposure to chloramphenicol (CAP) at doses used therapeutically was studied in pigs at the age of slaughter. Pigs were treated with CAP intramuscularly (20 mg/kg b.w. two times every 24 hours). Histomorphometrical and immunohistochemical analyses of small intestine and liver were done. CAP increased the thickness of myenteron and submucosa, and the length of villi; decreased the depth of crypts in the duodenum and jejunum. CAP influenced the Auerbach plexus. A decrease in cell proliferation, an increase in the number of apoptotic cells and T lymphocytes in the CAP-treated pigs were observed. CAP induces hepatotoxicity, neurotoxicity and disturbed intestinal epithelium. It can be concluded that short exposure of pigs to CAP at doses used therapeutically results in disturbed digestion and absorption process in the intestine.

Abstract

Introduction. Type 2 diabetes is a chronic disease with an epidemic character. Its prevalence is associated with lifestyle, many environmental factors, and genetic determinants. Implementation of diet therapy is the basis for treatment of the disease.

Aim. The aim of the study was to assess health behaviours and differences in these behaviours in type 2 diabetes patients taking their age into consideration.

Material and methods. The questionnaire survey was carried out among 120 subjects diagnosed with type 2 diabetes. The original questionnaire comprised questions on selected pro-health behaviours, e.g. prophylactic behaviour or self-monitoring in the disease. The statistical analysis was performed on 111 properly completed surveys. The respondents were divided into three age groups: subjects under 60 (n=24), between 60 and 75 (n=64), and over 75 years old (n=23).

Results. Regardless of their age, the patients with type 2 diabetes indicated mainly arteriel hypertension as a coexisting complication. The basic element of patients’ self-monitoring was checking the blood pressure and glycaemia. Half of the patients declared body weight control, however, a majority were characterised by excessive body weight and abdominal fat deposits, irrespective of their age. Walking was the most popular form of physical activity chosen by the respondents. Regardless of their age, the type 2 diabetes patients exhibited similar readiness for self-education related to their disease.

Conclusions. The surveyed respondents exhibited similar behaviours undertaken to keep healthy. The increase in the regularity of doctor appointments and in the use of pharmacotherapy was closely related to age of the respondents. The advanced age of the respondents had an impact on the regularity of foot inspection. Respondents over 75 years of age adhered to recommendations on the schedule of food and medicine intake, but used diet therapy less frequently.

Abstract

Introduction. Foodstuffs of special nutritional use and dietary supplements, especially in the case of sportsmen, have been known and widely used in human nutrition, nourishment, and convalescence for many years. Aim. The aim of the study was to assess the nutritional value of two groups of special dietary formulations and, in particular, to compare the nutrient and energy content declared by producers with that revealed by the present analyses. Material and methods. The nutritional value of two groups of formulations was assessed. The first group comprised formulations for undernourished subjects or those with contraindications to use diets with normal content of proteins and/or fats. The second group of formulations included products intended for strengthening the organism and targeted mainly at sportsmen. Samples of purchased products were analyzed for the content of basic components: dry matter, total protein, crude fat, crude ash, and structural carbohydrates. The content of carbohydrates and energy value was calculated mathematically. Additionally, the content of selected minerals (calcium, potassium, sodium, magnesium, iron, zinc, copper, manganese) was determined. Results. The content of carbohydrates, proteins, and especially fat in the chemical composition of the analyzed products declared by the producers differed from the levels determined in this study. In the mineral composition, differences were noted in the content of macroelements, while the content of micronutrients did not differ from the declared values. Despite the differences in the composition, the declared and calculated calorific values in all formulations were similar. Conclusions. There were differences between the declared and determined contents of nutrients in the analyzed formulations. The labels of the special-purpose industrial formulations purchased in pharmacies provided more information about their composition and nutritional value, whereas the information presented on the labels of the athlete supplements were less informative. Consumption of the supplements, in particular those dedicated for sportsmen, should be supervised by a doctor or dietitian.

Abstract

Introduction. Proper and healthy nutrition during pregnancy is one of the strongest external determinants of normal development of the foetus. Due to its health-enhancing properties, organic food is its desirable element. Therefore, the analysis of the consumer behaviour associated with organic food among pregnant women seems relevant, in particular given the small number of scientific reports addressing this problem.

Aim. The aim of the study was to analyse pregnant women’s behaviour and attitudes towards organic food. The investigations included opinions of the entire group of respondents and was intended to show differences between individual groups of women classified in terms of having children already or not.

Material and methods. The survey involved 100 pregnant women living in Lublin and its surroundings, which were assigned into two survey groups: women already having children and those without children. An anonymous questionnaire designed as part of the study was the research tool. The questions were focused on indication of the motivations in the purchase and sources of information about organic food as well as consumer behaviour on the organic food market.

Results. A majority of pregnant women assessed their financial situation as satisfactory. The main motive behind buying organic food was their wish to take special care of their health during the pregnancy period and the need to take care of the family. The women were familiar with the concept of organic food. Commercials were the frequent source of information among women expecting the first child and the Internet was the main source of information for those already having children. As specified by the pregnant women, health benefits, naturalness and the absence of chemical contamination are the characteristic features of organic food. Most of the respondents declared an intention to feed their children with organic food to minimise the exposure to chemical contamination.

Conclusions. There were differences in the use of sources of information about organic food or the importance of individual determinants of their purchase by the pregnant women. This knowledge can be used on the organic food market to develop marketing solutions, which will be useful in satisfying the needs of this group of consumers more effectively.

Abstract

The use of metal nanoparticles as supplements of animal diets does not always bring unambiguous results. There are many reports in the literature about the multifaceted effects of this type of supplementation on the animal organism. Therefore, the aim of the paper is to present the current knowledge of the possible application of nanometal forms in animal nutrition and its potential benefits and threats. The positive effect of nanoparticles used as feed additives has most frequently been reflected in an increase in body weight, higher average daily gain, or improvement of the FCR value. In some cases, however, the effect of nanoparticle addition to diets was indiscernible. The potent antibacterial activity of nanoparticles, especially against Gram-negative bacteria and Gram-positive bacteria, is regarded as a positive effect. In turn, the probability of their toxicity is a potential risk in application thereof. Supplementation of diets with nanometals has been accompanied by pathological changes in animal tissues, primarily in the pancreas, kidney, liver, rumen, abomasum, small intestine, adrenal glands, and brain. Additionally, at the the cellular level, nanoparticles were found to induce toxicity, inflammatory excitation, and cell death. Oral administration of nanoparticles induced a risk of malfunction of the nervous system and even impairment of cognitive processes in animals. The increasing knowledge of the possible toxic effects of nanoparticles on the animal organism suggests caution in their use in animal production and necessitates further precise investigations in this area.

Abstract

Faba bean (FB) seeds can be a good protein-energy component in animal feed. However, the presence of anti-nutritional substances is a negative feature of FB seeds. The aim of this study was to examine the influence of different levels of unprocessed FB seeds in feed on the gut-bone axis and metabolic profile in broilers. Ninety six, 1-day-old Ross 308 broiler chickens were randomly selected to one of the 3 dietary treatments (32 chickens in each, divided into 8 pens with 4 birds per each pen): the control group fed standard diet with soybean meal and without FB seeds, group I fed 8/15% (starter/grower) of high-tannin FB seeds, and group II fed 16/22% of high-tannin FB seeds. Bone mechanical examination, hematological and serum biochemical analysis as well histomorphometry of small intestine and liver tissue were performed. The intake of high-tannin FB seeds, irrespective of their amount, did not alter the bone geometric, mechanical and densitometric parameters nor influenced basal hematological parameters, however it resulted in: decreased serum concentration of total cholesterol and calcium; a reduced longitudinal myenteron of small intestine; increased mucosa and villus epithelium thickness, villus length, thickness and absorptive surface in duodenum; increased number of active crypts in jejunum; unchanged collagen area, intercellular space, and total cell number in the liver; decreased number of multinuclear hepatocyte cells. Moreover, the livers of birds fed the higher dose of high-tannin FB seeds had lymphocytic infiltrates in portal tracts and sinusoids. Feeding of unprocessed high-tannin FB seeds exerted an influence on the gastrointestinal tract by increased absorptive surface. In conclusion, the dietary inclusion of unprocessed high-tannin FB seeds had no negative effects on broiler growth, tibial bone mechanical properties and intestinal characteristics. Unprocessed high-tannin FB seeds may be used in broiler diets, but their dietary levels should not be higher than those discussed.
