    cadmium
    Opis:
    Cadmium is a dangerous occupational and environmental toxin. It accumulates in the human organism mainly in liver and kidneys. Cadmium half-life is about 10 years, so the symptoms of cadmium intoxication may occur several years after the exposure. Until now in treating intoxication with this metal chelating compounds have been used, burdened with numerous undesirable symptoms. In our investigations anthocyanins from Aronia melanocarpa were used to reduce the harmful results caused by cadmium. Administering anthocyanins with cadmium chloride resulted in a statistically significant decrease of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity, concentration of bilirubin and urea in blood serum and decreased cadmium cumulation in liver and kidneys in relation to animals receiving cadmium chloride only.

Eksperyment obejmował dziewiętnaście 20-minu-towych ekspozycji drganiami (nazywanych dalej treningami), w kolejnych dniach roboczych o stałej porze dnia dla każdej osoby. W trakcie każdego tre-ningu rejestrowano wytypowane parametry fizjologiczne przed i po tre-ningu, prowadzono stały monitoring pulsu HR i saturacji SpO2. Przed eksperymentem i po jego zakończeniu przeprowadzono badania biochemiczne.
    The effects of infrasound exposure were investigated at the Institute of Human Bio-physiology of the Academy of Physical Education in Kraków. The research program involved nineteen 20 min vibrations exposure sessions in the subsequent working days, at the same time of day for each participant. During each session selected physiological parameters were registered before and after the exposure, the heart beat rate HR and saturation levels SpO2 were monitored on the constant ba-sis. The research program was supported by the biochemical analysis before and after the experi-ments.

    sex difference
    Opis:
    Before blood constituents data can be applied as a diagnostic tool, general patterns related to sex, season and collection of fish and location need to be well documented and understood. The sex of the fish may also influence the blood parameters. In turn, the values of the different blood biochemical parameters significantly influence the physiological factors and sex of the fish. Hence, there is a need to assess before reporting the biochemical indices of the fish species. The present study was undertaken to know the difference between male and female blood biochemical parameters of the fish, Notopterus notopterus. The blood biochemical measurements included glucose, protein, total cholesterol, HDL and LDL-cholesterol, triglycerides, creatinine, enzymes-SGPT, SGOT and alkaline phosphatase. Furthermore, the electrolytes - sodium, potassium, calcium and phosphorous were compared with regard to sex. Moreover, the effect of sex on quantitative changes in fish blood was studied. The blood parameters between the sexes indicated that male fishes consistently had higher level of all biochemical parameters than did the female fishes, and this study may be a proposal as means of sexing fish. This indicates that the male fish is biochemically and nutritionally richer than the female; in female fish this effect may come about because much of the metabolites and nutrients are continuously being exhausted in the development of gonads (ovary). The results of this study could be used for monitoring the health and the physiological condition of the fish, Notopterus notopterus in a particular aquatic body.

    Opis:
    Introduction. Nicotine is an alkaloid that affects the functioning of the central nervous system and produces dependence. In low doses, it acts as a stimulant and relaxant. Nicotine was reported to have pro-cognitive effects in humans and animals. However, high doses of nicotine are harmful for many organs.The aim of the study was to check whether a 30-day exposure to transdermal nicotine affects memory and biochemical parameters in mice. Materials and method. A total of 32 mice (16 males and 16 females) were used in the experiment. Mice were divided into 4 groups of 8 animals each: I control-females receiving placebo patches for 30 days, II females receiving nicotine patches for 30 days, III control-males receiving placebo patches, IV males receiving nicotine patches. Spontaneous alternation and locomotor activity were examined weekly in a Y-maze. Body mass was recorded daily. On day 30, venous blood samples were obtained and the animals were anaesthetized with CO2. Their blood was used to measure alanine transaminase (ALT), asparagine transaminase (AST), cholesterol, creatinine and glycosylated haemoglobin (HbA1C). Results. Nicotine significantly improved memory in male mice on day 8. It increased ALT and AST activities in males and females, as well as the concentration of cholesterol in their blood sera. Conclusions. In conclusion, transdermal nicotine may produce transient improvement in fresh spatial memory in male mice, but it is not a long-term effect and therefore nicotine does not seem to be appropriate for use in the treatment of neurodegenerative disorders. It elevates blood cholesterol level and thus may increase the risk of atherosclerosis and cardiovascular events; moreover, it negatively affects liver enzymes. Nicotine use is therefore not recommended.

    Opis:
    Rivers are considered the most important sources of surface water on Earth. They are play a significant role in all human activities and the quality of river water is needed. Therefore, the importance of the water quality index is arising through providing data base about quality of the water source, and explain the change in the water quality over a period of time continually. This study involved determination of physicochemical and biological parameters of Lower Zab river in Kirkuk city at two different points. The objectives of the study are to assess the present water quality, through analysis of some selected water quality parameters like pH, TDS, BOD, dissolved oxygen, turbidity, EC, alkalinity, and salinity etc. and to compare the results with the Canadian Council of Ministers of the Environment and National Sanitation Foundation Water Quality Indices. Raw water samples were collected from the Lower Zab river twice a month by one sample every 15 days from each station. The water quality data include 16 different parameters. Tests were carried out following the American Public Health Association standard methods. The results show that all parameters values were within the standards of drinking water proposed by the CCME standards and Iraqi standards or the World Health Organization standards for drinking purpose, except turbidity, DO, nitrate, calcium, which were mostly higher than the standards and sometimes BOD and potassium. The results of WQI showed that the water quality at LZ3 station is lower than LZ2 station due to the polluting activity of the Lower Zab river. Furthermore, for the years 2014, 2015, and 2016, the water quality was degraded due to the ISIS war. Also, it was noted in the 2013 year that the water quality degraded more in fall and winter seasons due to that the earth has exposed to the long-dried season and then suddenly exposed to a high rainfall season which in turns leads to increase some parameters very high (i.e. turbidity). Finally, the Lower Zab river water cannot be use for drinking directly. However, a pretreatment is needed before the drinking use.

    Opis:
    This study examined the impact of oral supplementation with a new organic selenium preparation (selenitetriglycerides) on the health of camels (Camelus dromedarius). The experiment was conducted on 7 female camels, which were given 240 mg per animal per day of selenitetriglycerides with an oesophageal probe and subsequently monitored for 28 days. Blood samples for tests were collected 10 times (on day 1, 2, 3, 4, 5, 6, 7, 8, 14 and 28) and the following parameters were determined: the level of selenium, vitamin E, the activity of aspartate transaminase (AST), gamma-glutamyl transpeptidase (GGTP), lactate dehydrogenase (LDH), creatine kinase (CK) and the concentration of total protein, glucose, urea and creatinine. The following hematological parameters were determined in whole blood: white blood cell count (WBC), red blood cell count (RBC), hemoglobin level (HGB), platelet count (PLT) and packed cell volume (PCV). Selenium serum level increased significantly on the second day (from 40.18 µg l-1 to 198.79 µg l-1), peaked on day 7 (514.76 µg l-1) and remained at a statistically significant level relative to the baseline to the end of the experiment. Clinical observations and analysis of the hematological parameters, liver and kidney function parameters did not show any negative effect of selenitetriglycerides on camel health. The results indicate that selenitetriglycerides can be a safe and effective method of selenium supplementation in camels.

    Opis:
    ObjectivesThe aim of this study was to determine the physiological and biochemical changes among bakers, induced by heat exposure at the workplace.Material and MethodsInformation was collected by means of a self-administered questionnaire. Vital signs were measured and recorded by a trained nurse before and after each work shift. A venous blood sample was drawn at the end of each work shift. The mean wet-bulb globe temperature (WBGT) index in the bakeries and offices was measured.ResultsThis was a cross-sectional study involving 137 bakers working in 20 bakeries, and 107 control subjects comparable in terms of age, race, marital status, years of service, income, and cigarette smoking. There was a significant weight loss and increase in the respiratory rate, the heart rate, and oral body temperature among the bakers compared to the control group. Sodium levels were significantly lower, while blood urea nitrogen levels were significantly higher, among the bakers than in the control group. There were unfavorably hot working conditions in the bakeries: the WBGT index in the bakeries was 37.4°C while the average WBGT for the offices was 25.5°C.ConclusionsThe changes in the physiological and biochemical parameters among the bakers were found to be associated with exposure to high environmental heat in the bakeries, as judged by the WBGT index. Preventive measures should be aimed at reducing the adverse effects of heat exposure among bakers and should be directed towards the man-machine-environment triad.
