Unicrop seed meal and five of its fractions on different parameters of blood, plasma/serum and liver were studied in two experiments. Groups of four growing rats were pair-fed for 10 days on diets that contained the same amounts of ...

The case study at Bagerhat, Bangladesh revealed that almost all the water samples were contaminated by a hazardous level of arsenic that exceeding the World Health Organization recommended value of 0.05 mg/L for Bangladesh. Arsenic concentration of all the water samples ranged from 0.09 to 0.87 mg/L. The concentrations in soil and aurum samples were found to be in the range of 2.22-35.21 and 0.07-0.73 mg/kg, respectively. A positive correlation between arsenic concentrations in soil and water samples was observed. Aurum sample was found to be contaminated by arsenic to a harmful level if the corresponding water sample was also highly contaminated.

Method: The study was conducted among 46 somatization disorder patients and 45 healthy volunteers. Each patient was selected from different hospitals by random sampling. Serum trace elements concentrations were determined by flame atomic absorption spectroscopy. Statistical analysis were done using independent t-test, Pearson's correlation analysis, regression analysis and ANOVA. Result: Mn, Zn and Cu concentrations of somatization disorder patients were 1.133±0.45 (mg/L), 1.216±0.352 (mg/L) and 1.491±0.499 (mg/L), while these were 0.987±0.216 (mg/L), 1.209±0.277 (mg/L) and 0.962±0.684 (g/L) in control subjects respectively. The serum concentration of Mn and Cu increased significantly (P=0.00; P=0.022 respectively) in somatization disorder patients while the concentration of Zn (P=0.954) remained unchanged. Socioeconomic data reveals that most of the patients were poor, middle-aged and unmarried. Mean BMI of the patients (20.26±3.04) and the control subjects (23.56±2.03) was in normal range. Pearson's Correlation analysis suggested that only Cu concentration of patients had a significant inverse correlation with the BMI (r = −0.462, p = 0.010), which was further justified from the regression analysis (R 2 = 46.3%; t = −2.876; p = 0.003) and one-way ANOVA test (F = 8.135; p = 0.010). Conclusion: This study depicted a significant increase in the serum concentration of Cu and Mn in somatization disorder patients than that of its control counter parts, which may provide prognostic tool for the diagnosis of this disease. Still the authors suggest further studies to confirm these findings (German J Psychiatry 2007; 10: 41-45).

It has been estimated that nearly 50.6 million under-five children are malnourished, and almost 90% of these children are from developing countries. Bangladesh is one of the countries with the highest rate of malnutrition. The recent baseline survey by the National Nutrition Programme (NNP) showed high rates of stunting, underweight, and wasting. However, data from the nutrition surveillance at the ICDDR,B hospital showed that the proportion of children with stunting, underweight, and wasting has actually reduced during 1984-2005. Inappropriate infant and young child-feeding practices (breastfeeding and complementary feeding) have been identified as a major cause of malnutrition. In Bangladesh, although the median duration of breastfeeding is about 30 months, the rate of exclusive breastfeeding until the first six months of life is low, and practice of appropriate complementary feeding is not satisfactory. Different surveys done by the Bangladesh Demographic and Health Survey, United Nations Children's Fund (UNICEF), and Bangladesh Breastfeeding Foundation (BBF) showed a rate of exclusive breastfeeding to be around 32-52%, which have actually remained same or declined over time. The NNP baseline survey using a strict definition of exclusive breastfeeding showed a rate of exclusive breastfeeding (12.8%) until six months of age. Another study from the Abhoynagar field site of ICDDR,B reported the prevalence of exclusive breastfeeding to be 15% only. Considerable efforts have been made to improve the rates of exclusive breastfeeding. Nationally, initiation of breastfeeding within one hour of birth, feeding colostrum, and exclusive breastfeeding have been promoted through the Baby-Friendly Hospital Initiative (BFHI) implemented and supported by BBF and UNICEF respectively. Since most (87-91%) deliveries take place in home, the BFHI has a limited impact on the breastfeeding practices. Results of a few studies done at ICDDR,B and elsewhere in developing countries showed that the breastfeeding peer-counselling method could substantially increase the rates of exclusive breastfeeding. Results of a study in urban Dhaka showed that the rate of exclusive breastfeeding was 70% among mothers who were counselled compared to only 6% who were not counselled. Results of another study in rural Bangladesh showed that peer-counselling given either individually or in a group improved the rate of exclusive breastfeeding from 89% to 81% compared to those mothers who received regular health messages only. This implies that scaling up peercounselling methods and incorporation of breastfeeding counselling in the existing maternal and child heath programme is needed to achieve the Millennium Development Goal of improving child survival. The recent data showed that the prevalence of starting complementary food among infants aged 6-9 months had increased substantially with 76% in the current dataset. However, the adequacy, frequency, and energy density of the complementary food are in question. Remarkable advances have been made in the hospital management of severely-malnourished children. The protocolized management of severe protein-energy malnutrition at the Dhaka hospital of ICDDR,B has reduced the rate of hospital mortality by 50%. A recent study at ICDDR,B has also documented that home-based management of severe protein-energy malnutrition without follow-up was comparable with a hospital-based protocolized management. Although the community nutrition centres of the NNP have been providing food supplementation and performing growth monitoring of children with protein-energy malnutrition, the referral system and management of complicated severely-malnourished children are still not in place.

The study was conducted among 30 schizophrenic male patients and 30 healthy male volunteers. Patients were recruited from Bangabandhu Sheikh Mujib Medical University by random sampling. Hair trace element concentrations were determined by flame atomic absorption spectroscopy and analyzed by independent t test, Pearson's correlation analysis, regression analysis, and analysis of variance (ANOVA). Mn, Zn, Ca, Cu, and Cd concentrations of schizophrenic patients were 3.8±2.31 μg/gm, 171.6±59.04 μg/gm, 396.23±157.83 μg/gm, 15.40±5.68 μg/gm, and 1.14±0.89 μg/gm of hair sample, while those of control subjects were 4.4±2.32 μg/gm, 199.16±27.85 μg/gm, 620.9±181.55 μg/gm, 12.23±4.56 μg/gm, and 0.47±0.32 μg/gm of hair sample, respectively. The hair concentration of Zn and Ca decreased significantly (p=0.024; p=0.000, respectively) and the concentration of Cu and Cd increased significantly (p=0.021; p=0.000, respectively) in schizophrenic patients while the concentration of Mn (p=0.321) remain unchanged. Socioeconomic data reveals that most of the patients were poor, middle-aged and divorced. Mean body mass indices (BMIs) of the control group (22.26±1.91 kg/m 2 ) and the patient group (20.42±3.16 kg/m 2 ) were within the normal range (18.5−25.0 kg/m 2 ). Pearson's correlation analysis suggested that only Ca concentration of patients had a significant positive correlation with the BMI (r= 0.597; p=0.000) which was further justified from the regression analysis (R 2 =44%; t=3.59; p=0.002) and one-way ANOVA test (F=3.62; p=0.015). A significant decrease in the hair concentration of Zn and Ca as well as a significant increase in the hair concentration of Cu and Cd in schizophrenic patients than that of its control group was observed which may provide prognostic tool for the diagnosis and treatment of this disease. However, further work with larger population is suggested to examine the exact correlation between trace element level and the degree of disorder.
