Eating habits of 40-year-old women (n=592) were evaluated in the study. The women were participants of the programme “Prophylaxis of cardiovascular diseases in the population of 40-year-old citizens of Wrocław” carried out under the auspices of the Health Department of the City Office of Wrocław. In the study, use was made of a 24-h recall method and history of nutrition that included, among other things, average daily number of meals, frequency of meal consumption and food preferences. The examined women were also subjected to analyses of concentrations of total cholesterol, HDL cholesterol fraction and blood glucose as well as measurements of blood pressure and calculations of Body Mass Index (BMI). The study demonstrated the presence of overweight in 27% of the women examined, obesity in 10% of the women, elevated blood level of total cholesterol in 51.7% of the women, elevated blood glucose level in 17% of the women, and elevated systolic blood pressure in 15% of the women. The statistical analysis indicated a significant, unfavourable effect of BMI index on blood pressure and some lipid indices. In the group of women examined (n=592), the risk of cardiovascular disease was estimated in a 10-year period of observations based on Framingham Heart Study criteria. A high risk, i.e. 11–30%, was demonstrated for 25 women.
The study was carried out on 4200 turkey broilers Big 6, from which after a 3-week breeding an experimental group was separated. The group was receiving an addition of bioplex-Cu 0.5g/L of drinking water till the end of the experiment. The haematological and biochemical factors were examined in the 8th week of the turkeys life, in blood taken from the wing vein of 10 randomly chosen birds (5 cocks and 5 hens) from both experimental and control group. In the obtained samples, Ht, total protein level, a-NH2 nitrogen, glucose, and the Cu, Fe, Zn and Ca level were determined. Also, in the bioplex-Cu and in the feeds used, Cu, Fe, Zn and Ca were determined by the spectrophotometry of atom absorption method after dry mineralization. The applied bioplex-Cu statistically significantly increased the haematocrit and glucose level. The addition of Cu also caused an increase in the concentration of this element in the plasma of turkey blood. The significantly increased Cu level did not cause interaction with other components of the feed and did not disturb the Fe, Zn and Ca absorption to the turkey blood.
In order to compare the effect of organic and mineral fertilization of various soil types, long-term fertilization experiments frequently use indices, being a function of various parameters considered simultaneously; the content of organic carbon, microbiological parameters and soil enzymatic activity. The aim of the present research was to define soil fertility based on the values of Biochemical Soil Fertility Index (B). The index has been formulated based on the research results obtained: enzymatic activity, content of organic carbon and total nitrogen. The research material was sampled from topsoil of a many-year experiment which included varied organic and mineral fertilization, established on typical lessive soil. Soil samples were collected in 1998 from winter wheat stand, four times over the vegetation period. The following enzymes were determined: dehydrogenases, alkaline phosphatases, proteases and amylases. Additionally Corg and Ntotal and pH in 1 M KC.
A study was undertaken to determine the effect of a synthetic immunomodulator, i.e. methisop- rinol applied in ovo, upon the hatchability of turkey poults under conditions of a standard hatchery as well as on their health status evaluated based on analyses of selected biochemical indices in their blood serum. Experiments were conducted on 5 groups of BUT 9 turkeys at the age of 5 days (35 birds in each group) hatched from eggs to which methisoprinol (VetAgro, Lublin, Poland) was applied in ovo at a dose of 5 mg (group I), 10 mg (group II) or 20 mg per egg (group III) on the 26th day of incubation. Turkeys hatched from eggs to which a physiological solution of NaCl was applied on the same day at a dose of 0.1 ml per egg (group IV) as well as those hatched from eggs without in ovo injection (group V) served as controls. Five hundreds eggs were used in each group. Hatchability was evaluated based on the number of hatched poults in respect of the number of eggs with live embryos transferred from the setting compartment to the hatching compartment, that were subjected to in ovo administration of the preparations according to the experimental design. Blood serum of the 5-day-old turkey poults was analyzed for activities of AST, ALP, LDH-L, CK, lysozyme and cerulop- lasmine as well as for total protein and albumin contents. Analyses were also conducted for the immune system organ index - percentage contribution of organs of the immune system (spleen, thymus and the bursa of Fabricius) in the body weight of turkeys. The study demonstrated that methisoprinol administered to turkey embryos in ovo on day 26 of incubation at doses of 5, 10 or 20 mg per embryo did not induce any disturbances in the hatching process or affect its final result. In addition, it was shown not to exert any negative effect on the health status of the reared turkey poults.
Badaniem objęto 25 krów rasy czarno-białej, w wieku 4-8 lat, o wysokiej wydajności mlecznej (średnia wydajność mleczna krów wynosiła 5123). W dziennej dawce żywieniowej krowy otrzymywały 30 kg kiszonki z kukurydzy, 20 kg buraków, 3 kg siana oraz paszę treściwą do 2 kg dziennie. Wszystkie krowy były badane klinicznie, a materiał - krew i mocz - od nich pobrany poddano analizom laboratoryjnym. Badania prowadzono czterokrotnie: 2 tygodnie przed poro­dem, tydzień, miesiąc i 2 miesiące po porodzie. Jednorazowo przeprowadzono badania koproskopowe i badanie moczu. W zakresie badań hematologicznych oznaczano Ht, Hb, Erys, w zakresie badań biochemicznych - poziom białka całkowitego i jego frakcji, aktywność AspAT, GGTP, AP, ChE, stężenie glukozy, WKT i związków ketonowych. Uzyskane wyniki wskazują na istnienie zaburzeń u badanych krów, polegających na zachwianiu gospodarki energetycznej. Oznaczane wskaźniki okazały się wystarczające do ich diagnozowania. Powyższe badania dały podstawę do prowa­dzenia postępowania zapobiegawczego i terapeutycznego.
