The effect of water intake prior to blood sampling on subsequent packed cell volume (PCV) was investigated in ewe lambs (8 months of age) of the Dohne Merino, Merino and Letelle flocks at Grootfontein Agricultural Development Institute. On the afternoon of the day before the experiment was conducted, a blood sample for a baseline PCV value (R) was taken from each animal. The following day, 15 ewes of each breed (n=45) were dosed with 1 litre of water and another 15 of each (n=45) were used as a control. Blood samples for PCV were taken concurrently for both the control and water treatment groups before the dose (0), and at 15, 30 and 60 minutes after dosing . PCV were subsequently determined with the microcapillary centrifuge technique. Baseline PCV of Letelle ewes was higher (32.4 + 0.6) than that of the Dohne Merino (29.7 + 0.6) and Merino (28.7 + 0.6) ewes. Furthermore, recovery rate at 30 minutes after treatment also differed among breeds. Although there were significant differences between the control and water treatment groups at R and 0 minutes, which were probably due to inherent animal differences, there were no significant differences between PCV of the 2 groups during the remainder of the experimental period. Overall it can be concluded that water intake before blood sampling for the determination of PCV has no significant effect on haematocrit. Differences among breeds were more pronounced than those between treatment groups.

Drinking Water Sources

The study focused on existing condition of drinking water and evaluates the performance of pond sand filters (PSFs) as a safe drinking water source of three selected Union of Dacope Upazila, Khulna in south-west coastal part of Bangladesh. This study exposed that the un-treated pond water is the main drinking water sources (54 %) in the study area. Other options for drinking water are PSF (43 %) and rain-water harvesting (RWH) systems (3%). The people who are using pond water directly as drinking water are suffered (67%) from various water-borne diseases in different times of the year. Most of the PSF users satisfied with the existing system of PSF. In most cases 85% the beneficiary’s willingness to pay for maintaining of PSFs. The water qualities were tested for the raw and treated water at various steps of the treatment process. The laboratory analysis showed that turbidity, pH, nitrate (NO3), ammonia (NH3), total dissolved solid (TDS), elec-trical conductivity (EC) and phosphate (PO4) of the PSFs water meet the Bangladesh standard, but the microbial contaminations are failed to meet the Bangladesh standard. In the raw water from three PSFs, the fecal coliform ranges are 64,122 and 136 CFU/100ml. After the treatment the fecal coliform ranges were 9, 19 and 38 CFU/100ml respectively. The outcome of the study provided information to ensure safe and adequate quantity of drinking water system in a disaster-prone coastal area of Bangladesh. It seems that if the PSF installs more in this region and takes action in regular monitoring and proper management, therefore, it will be one of the most sustainable drinking water sources for this coastal region.

Background: High dietary salt intake from food is a major risk factor for raised blood pressure (BP) worldwide.  In the context of Bang ladesh , information regarding salinity in water and blood pressure especially in the  adolescent population is very scarce.  This study  was conducted  to  assess  the  blood  pressure  status  of  adolescent  school  children in coastal area of Bangladesh. Methods: A one-year school based cross-sectional study was carried out among 528 students of class 8-10 at schools of Bajua Union, Dacope Upazilla, saline prone zone of Khulna district. Relevant data were collected by using pre tested semi-structured questionnaire with face to face interview & checklist. Blood pressure was mea sured in a controlled environment and Collected water sources were analyzed by DPHE, Water Testing Laboratory. The study was conducted in the schools of Bajua Uni on, Dacope Upa zilla of the saline prone zone of Khulna district in between a one-year time frame. Results:  Among 528 participants most of them  were male (353, 66.9%) with an age of 14 years (185  ,  35.0%).  Most of them were read in class 8 (185 , 35.0%). Prevalence of paternal, maternal, paternal grandparents' and maternal grandparents' history of hypertension were found significant. About 72.3% regularly took extra salt during meal and 43.9% took salt preserved fish with  meal. Mean of systolic blood  pressure  of respondents were 114.2197 ± 7.61448  mm of Hg. Mean of diastolic blood pressure of respondents were 75.1 780 ± 5.45959 mm of Hg. Mean of pulse pressure of respondents were 39.0417 ± 6.56430. Mean of mean arterial pressure of respondents  were 88. I 9  I 9  ±  5.44267 mm of Hg. Sodium concentration of pond were approximately in between 500-600 mg/I, whereas in  tube  wells approximately in between 700-1 I 00 mg/I. Conclusion: Drinking water sodium is an important source of daily sodium intake , and therefore a risk factor for increased BP in salinity prone coastal areas. This adds to the cardiovascular health risks associated with food sodium intake in Southeast Asian populations. Low- saline alternative drinking water sources could effectively help to prevent high BP and hypertension-related morbidity and mortality in these coastal populations. New technologies for the supply of such alternative sources, including safeguarding the microbial quality , should be further studied. JOPSOM 2020; 39(1): 60-66
