A 14-day-long stay of carp in blue, yellow, and red aquaria caused statistically significant increase of ACTH and cortisol in the blood of the fish studied, compared to the initial state and to the aquarium in natural colours.
The present studies revealed that the transportation and the associated change of environment, causing statistically significant cortisol level rise, led to the increase of sodium- and chloride-ion levels and osmolarity; as well as to the fall of potassium-ion concentration in the blood of carp. Despite the persistence of the high level of cortisol in the blood of carp, throughout the whole 7-day-long monitored period, the levels of Na+, Cl-, and the blood osmolarity came back to normal. The exception were potassium ions, whose concentration on the 7th day after the transfer were still statistically lower than the initial values.
The study was aimed at determining the blood glucose, lipid, and lipoprotein levels in post-mastectomy women treated with Tamoxyphene. The women's eating habits and effects of health-promoting education on the blood parameters were analysed. A 4-month-long health-promoting education aimed at improving the participants' carbohydrate-lipid metabolism resulted in a statistically significant (P˂0.05) decrease in triacylglycerol (from 145.8±87.9 to 121.3±46.0 mg/DL) and LDL cholesterol (from 135.0±33.8 to 120.8±19.7 mg/DL) levels as well as in a desired individual normalisation of glucose and total cholesterol levels. Additional effects included a slight body weight reduction and changes in BMI (Body Mass Index; from 26.6±4.1 to 26.3±3.6) and WHR (Waist/Hip Ratio; from 0.82 ±0.05 to 0.79 ±0.05). Evaluation of the nutritive value of daily food rations showed an appropriate total protein consumption at a reduced caloric value, the animal protein contribution being, however, still to high. Carbohydrate intake was in a lower part of the recommended range, while fat consumption exceeded the recommended range. A too low intake of dietary fibre, beta karo tene, vitamin B6, and Ca + +, Mg+ + , and Zn++ was revealed. Following the nutrition course, the diets' caloric value increased slightly, consumption of complex carbohydrates with fibre increasing as well. Additionally, an increase was recorded in consumption of the vitamins and minerals taken into account.
The effect of health-promoting education in nutrition and the resultant changes in incorrect eating habits on levels of insulin, triacylglycerols, total cholesterol and its LDL (low density lipoprotein) and HDL (high density lipoprotein) fractions, as well as reduction of body weight and changes in the values of BMI (body weight index) and WHR (waist/hip ratio) indices were examined in obese women being in climacterium. It was found that the correction made to diet and the change in eating habits consisting in the first place in normalisation of timing, volume and type of consumed meals, and in adjustment of amounts of specific nutrients to individual needs, brought a statistically significant (P≤0.01) decrease in the level of insulin (from 27.2 to 21.9/µIU/mL), triacylglycerols (from 124.4 to 86.1 mg/dL), total cholesterol (from 226.7 to 181.2 mg/dL) and its LDL fraction (from 150.4 to 119.2 mg/dL) and a statistically significant (P≤0.05) decrease in the level of HDL cholesterol fraction (from 52.6 to 45.1 mg/dL). After four months of using modified diet, another decrease was observed in the level of insulin (to 16.9 mg/dL) and triacylglycerols (to 69.9 mg/dL), with further reduction of the total cholesterol level and a slight increase in the level of LDL cholesterol, and returning the level of HDL cholesterol almost to the initial state. This was accompanied by a slow but consistent reduction of body weight (10.26±4.53 kg, with 0.57±0.18 kg/week on the average) and a decrease in the value of BMI (from 36.15 to 32.20) and WHR (from 0.84 to 0.80) indices.
W prozdrowotnej edukacji uczestniczyło 187 kobiet zawodowo pracujących, w wieku 45-52 lat, których BMI > 30,0 i > 40,0 wskazywał na otyłość 11° i 111°. Informacje o żywieniu zebrano dwukrotnie, przed i po zakończeniu edukacji. Badane kobiety, po odpowiednim poinstruowaniu na bieżąco notowały czas, rodzaj i ilość spożywanej żywności w 3 losowo wybranych dniach tygodnia. Wielkość porcji oceniano przy użyciu „Albumu porcji, produktów i potraw". Zebrane dane opracowano przy użyciu komputerowego programu „Dietetyk" wersja 2.5. Oceniane jadłospisy pochodziły z pierwszych dni października i połowy stycznia. Stwierdzono, że 4-miesięczna prozdrowotna edukacja żywieniowa spowodowała: unormowanie czasu, ilości i rodzaju spożywanych posiłków; statystycznie istotne p < 0,01 obniżenie kalorycz- ności diety, spożycia białka ogółem i korzystną zamianę białka zwierzęcego na roślinne, spożycia tłuszczów ogółem w tym tłuszczów nasyconych i spożycia sacharozy oraz statystycznie istotny p <0,01 wzrost spożycia węglowodanów złożonych, włókien pokarmowych, witamin Bs, PP, C, wapnia oraz płynów. Towarzyszyła temu powolna ale systematyczna redukcja masy dala i obniżanie się wartości wskaźników BMI i WHR.
W przeprowadzonym doświadczeniu badano wpływ zmian składu diety na zawartość i lokalizację tkanki tłuszczowej u kobiet otyłych w okresie menopauzalnym. Stwierdzono, że czteromiesięczna edukacja żywieniowa spowodowała obniżenie wartości energetycznej diety, obniżenie spożycia białka ogółem, w tym białka zwierzęcego, tłuszczów ogółem w tym tłuszczów nasyconych, cholesterołu i sacharozy. Wzrosło natomiast spożycie białka roślinnego, skrobi, błonnika pokarmowego, witamin B6, PP i beta-karotenu oraz składników mineralnych: Ca, Mg i Zn. Zmianom tym towarzyszyła powolna ale systematyczna redukcja masy ciała (średnio 6,98±1,60 kg w badanym okresie, 0,44±0,16 kg/tydzień) spowodowana utratą nie tylko podskórnej (-0,41±0,16 cm, powłoki brzuszne, pomiar na wysokości kręgu L4) ale też wisceralnej (-1,21±0,48 cm, pomiar na wysokości kręgu L4) tkanki tłuszczowej. Zmianom tym towarzyszyło obniżanie się wartości wskaźników BMI (z 36,2±4,3 do 31,1±3,9) i WHR (z 0,90±0,08 do 0,85±0,06).
The aim of the present study was to evaluate the effects of enriching the uncorrected diet of post-mastectomy women with a hull-less oat Akt cultivar on the subjects' blood glucose, triacylglycerol, total cholesterol, HDL- and LDL-cholesterol, fibrinogen, and estradiol levels. The cholesterols were assayed in a closed system, with Roche reagents in an Integra biochemical analyser. The fibrinogen level was determined, following clotting, with a Behring BCT DADE, while estradiol was assayed by chemoluminescence in a DPC Immulite instrument. The subjects consumed oat grains 3 times a week, for 4 months, in amounts constituting 10-15% of the diet energy value. Whenever consumed, oats replaced a carbohydrate product usually served for a meal (e.g. bread for breakfast, lunch or dinner, or potatoes, grits, rice, pasta etc. for lunch or dinner). The oat enrichment was found to produce a statistically significant (P<0.01) reduction in the glucose (from 98 to 90 mg/dL) and HDL-cholesterol (from 59.3 to 55.9 mg/dL) levels as well as a significant (P<0.01) increase in the fibrinogen concetration (from 280 to 361 mg/dL). The post-hysterectomy women showed a significant (P<0.05) increase in the blood estradiol level (from 10.0 to 19.5 pg/mL). Changes in triacylglycerol (from 126 to 130 mg/dL), total cholesterol (from 206 to 202 mg/dL), and LDL-cholesterol (from 122 to 115 mg/dL) levels as well as those of estradiol (from 62 to 290 pg/mL) in those subjects with intact ovaries were in significant.
The effect of health-promoting education in nutrition and the resultant changes in eating habits, with a particular reference to the substitution of sucrose with starch and a reduced lipid consumption, on the blood levels of insulin, Cortisol, glucose, triacylglycerols, and total lipids in mature obese women was analysed. The levels of all the components analysed were found to decrease statistically significantly (P≥0.01) after two months on a modified diet. The levels, except those of insulin, did not change after the subsequent two months of the diet; at the end of the fourth month, the insulin level was statistically significantly (P≤0.05) lower than that recorded after two months. In addition, while maintaining the energetic value of the adjusted diet at a level similar to that of the uncorrected one, a slow but consistent reductions of the subjects' body weight (BMI) and waist to hip ratio (WHR) were recorded.
The effects of isocaloric substitution of dietary carbohydrates from whole cereal grains with carbohydrates from white flour and sucrose on body weight gain, body chemical composition, fatty acid profiles, and concentrations of corticosterone and thyroxine (T4), two hormones enhancing or promoting lipolysis, were followed experimentally. The change in source and type of dietary carbohydrates was found to be accompanied by a reduction in the blood corticosterone concentration (from 115.3±54.6 to 44.9±29.8 ng/mL) in males only; the reduction could have facilitated adipose tissue accumulation (body weight gain from 1.22±0.97 g per 100 g standard diet to 1.68±0.58 g per 100 g modified diet). As, however, the females receiving the modified diet did show increased adipose tissue accumulation as well (from 1.32±0.47 to 2.23±0.80 g per 100 g feed consumed), with only a slight corticosterone concentration increase (from 52.2±20.0 to 67.4±336.7 ng/mL), it seems that the adipose tissue accumulation mechanism in females must have been different. No significant effect of the modified diet on thyroxine concentration was detected.
Present studies yielded the following conclusions: the transport caused statistically significant rise of ACTH and cortisol concentrations in the blood of carp reared in the thermal-effluent channel. Usage of glass tanks for accommodating the fish caused prolongation of the stress reaction and maintenance of high ACTH and cortisol levels beyond the 7-day period monitored in the present experiment.
