A purpose of the research was to analyze chosen dietary recommendations suggested by Carolyn Mein, who has worked out the diet idea based on body typology. According to the results a lot of differences have been showed between mentioned dietary advices and directives of the rational nutrition. The 24 hours energy need, defined by Carolyn Mein, mostly occurred to stay under suggested norms. More over there were other mistakes including: broad quantity ranges for the basic nutrition ingredients, huge share of proteins in diet, small of carbohydrates and proportionally big share of fats as well as the identical values of caloric demands for each type. Exerted in the analysis small far too share of plant oils, grain products as well as vegetables and fruits, together with the often suggestions of consumption of products consisting of saturated fat acids can be the reason of increased risk of civilization diseases, most of all the blood system ones and diabetes among group of people following the Mein's diet. Broad quantity ranges of the basic nutrition ingredients and not precise description of the product feeding frequency may cause difficulties in practical diet suggestions usage.

Almost 80% of Polish consumers declare to know the term „organic food". Majority of the respondents associated organic food production with „clean environment" and „exclusion of agrochemicals" One can assume that Polish consumers do not have sufficient knowledge on organic criteria since they tend to believe that it is possible to use minimum level of agrochemicals in organic food production. Consumers perceive organic food as „natural", „healthy" and „safe". They have positive association with organic food in terms of its health safety and potential positive impact on human health.

W niniejszej pracy zmierzono tempo podstawowej przemiany materii 6 młodych dorosłych osób i porównano je z wartościami obliczonymi ze wzorów. Pomiary wykonano aparaturą respirometryczną firmy Maihak w pomieszczeniu termostatowanym istniejącym w Katedrze Dietetyki SGGW. Uzyskane wyniki są zbieżne z danymi zawartymi w normach żywieniowych opublikowanych w USA, gdzie poziom wartości energetycznej diety zalecanej na przykład dla mężczyzn w wieku 23-50 lat i o masie ciała 70 kg waha się w granicach od 2300 kcal/d do 3100 kcal/d, czyli uwzględnia różnice indywidualne rzędu 30%.

The starting point for energetic value of the diet is basic metabolism rate (BMR). It's value is evaluated with the formulas proposed by WHO which have been applied in Poland since 1995 [4]. These formulas take into account sex, age and body mass of human. These formulas present average values which arc representative for multimillion populations of people who arc of different nationality but have similar parameters as above mentioned. There is very few published data about variability between and within individuals in the discussed scope. Experts' Commission of FAO/WHO/UNU [7] published that variability factor which characterizes variability of weekly metabolism of people with similar parameters which were taken into account is 12,5 %, and analogical factor calculated for the same persons examined on different days varies between 10 to 6 % . In this research basic metabolism rate of 6 young adult persons was measured and compared with values calculated with formulas. The measurements were performed with respirometry equipment produced by Maihak company in thermostatic room which is in Department of Dietetics of Warsaw Agriculture University. It was shown that standard deviation of 6 differences calculated between individual theoretic values of B M (calculated with formulas) and real values which were measured were as 4,13 % of arithmetical average of results which were taken into account. In some cases that difference was over 1000 kJ/d which is 13,4 % of value calculated with formulas. If we take into account that we often increase that value by about 50% to estimate 24 hour energy expenditure which takes into account thermogenesis effected by nutrition and energetic cost of movement activity, the discussed difference between the value calculated with formulas and real value which was individually measured increases to the level of 20 % of the former value (calculated with formulas). Received results are similar with data included in nutrition standards published in USA [6], where the energetic value of recommended diet e.g. for man (m) of age 23-50 years and body mass 70 kg varies between 2300 kcal/d to 3100 kcal/d, and is taking into account individual differences in the rank of 30%. The differences in the rank of 20% proved in this relatively small research, which were between values estimated on the commonly applied formulas and real values which were measured states that there is so low preciseness of commonly performed estimation of 24 hour human energy expenditure, that it truly discredits appropriateness of this type of dietary guidance.

The objective of the undertaken study was to evaluate physical measures and body composition of elderly people in connection with the degree of independence in meals preparation. Study was carried out in 2003 and 2004 on the group of 61 people (34 women and 27 men), belonging to two age groups (65-74 and 75+ years old), and living near Olsztyn. Participants were recruited using snow ball method. The evaluation of physical measures and body composition was conducted on the group of 40 people (20 women and 20 men) using anthropometric methods. The assessment of bone tissue was performed by the ultrasonographic method. Participants' involvement in meals preparation at home was determined on the basis of SENIOR FOOD QOL questionnaire. Appearance of overweight or obesity was observed in about 90% of participants, including obesity of androidal type in more than half of eases. In 34% of participants the risk of ostheopenia and in 66% of participants the risk of ostheoporosis was confirmed. It was found that there is no relation between somatic and densitometric indices and degree of independence in meals preparation in elderly people.

In this work the capillary clectrophoretic method, with liquid-liquid extraction, for the isolation and determination of the ivermectin in animal serum and tissues is presented. Ivermectin is a drug with a broad spectrum of activity against nematodes and arthropod parasites in food-producting animals such as sheep, cattle, pigs, horses. The method was statistically validated for its linearity, accurancy, precision and selectivity. A typical standard curve encompassing a range of 1 to 20 µg/kg ivermectin was linear (correlation coefficient r=0.9992). The lowest level validated in scrum and tissue by the method was 1 µg/kg and the limit of detection was 0.3 µg/kg. The average recovery from samples was 80.72%. The inter-assay precision was expressed as the mean SD and relative standard deviation (RSD). This characteristics make this method attractive when compared to classical isolation and determination procedures for ivermectin. The analytical method was successfully applied to determination for ivermectin residue in tissues and for pharmacokinetic studies.

The use of veterinary drugs (antibiotics, coccidiostatics) to treat animal disease and to promote fast, more efficient growth of livestock is a common practice in modern agriculture. In order to protect the health of the consumer of foodstuffs of animal origin, one of the most important principles laid down in the legislation is that foodstuffs obtained from animals treated with veterinary medicinal products must not contain residues of the medicine or its metabolites which might constitute a health hazard for the consumer. One of the most common anticoccidial drug used in EU to 2003 was nifursol. The aim of this study was to develop a confirmatory analysis by capillary electrophoresis (CE) for nifursol residues in edible tissues (muscle, skin with fat, liver and kidney) of turkey origin. The whole of nifursol determination procedure was validated. The described method is specific, sensitive, precise and accurate enough for determination residue of veterinary drugs in tissue of animal origin and could be used for therapeutic drug monitoring.

Methods of honey bee care against various diseases in Poland are based on usage of veterinary drugs, which can be found in bee products and cause their toxic effects on human organism. This research is focused on sulfa drugs - used as a veterinary drug against Bacillus larvae - etiological factor of American foulbrood disease. According to European Union law, any appearance of sulfa drugs is forbidden. Unfortunately Polisulfamid (mixture of three sulfonamides - sulfacetamide (SFA), sulfatiazole (SFT) and sulfadimethazine (SFM)) has used by polish beekeepers. Samples were prepared by solving 2.5 g of honey in 12.5 ml of acctic buffer (pH=5). The clean up of honey sample, mainly from sugar components, was performed on a solid phase extraction column. After a SPE percolation, clution of sulfonamides with acctonitrylc, evaporation in nitrogen stream and dilution in water was made. The prepared solution was placcd on Silica Gel for chromatography. After the thin layer chromatography is finished, the platelets arc revealed with fluoresceine and watched under UV lamp of wave length 254 nm. The method occurred to be sensitive enough to determine presence of sulfacetamide and sulfatiazole white sulfadimethazine contamination of honey bee honey in smallest quantities that previously have been determined using HPLC. It has been shown that the method is much easier to perform and cheaper for screening detection sulfonamides in natural honeys.
