The main objective of this paper is to highlight the present investment related laws and regulations in Bangladesh. An analysis has been made to depict different aspects and their impacts on formulations, promotions, incentives and facilities support provided by BOI, BEPZA, BSCIC, Ministry of Finance, Bangladesh Bank and National Board of Revenue to both local and foreign investors. The results of the study indicate that variables related to investment in Bangladesh are highly positive for economic growth and industrial development of the country.

High fatality rate in road accident of Bangladesh warrants immediate repair of the faulty roads. ... more High fatality rate in road accident of Bangladesh warrants immediate repair of the faulty roads. But due to limited amount of resources, it requires a prioritization of road improvement functions. One of the important factors for road maintenance prioritization is road safety. Road fatality risk is lavishly used for measuring road safety. Most deserving tool for measuring fatality risk exposure ? “fatalities per million kilometers traveled” requires information over road fatality and vehicles per hour in every specific links of national roads. The Road Maintenance Management System (RMMS) of Roads and Highway Department (RHD) of Bangladesh provide vehicle per hour information based on road links that belongs to multiple administrative segments of Bangladesh. On the other hand, Bangladesh Roads Transport Authority (BRTA) provides information over road fatalities corresponding to administrative segments. This creates problem in priority score calculation and allocating limited funds among many administrative segments so that the reduction of road fatalities can be achieved in best possible way. However recent adaption of geographic information system (GIS) for administrative and road information allows revealing road length data and thus approximating the information required for measuring fatality risk exposure. This research explains a methodology to identify a verified fatality index for prioritizing national road maintenance and also ranks the districts of Bangladesh using such methodology. The Ministry of Communication and Transportation, RHD and the respective district administration can use this methodology for scheduling the required maintenance of national main roads and thereby can reduce road accident fatalities in Bangladesh.

Conjunctival smears were collected from the infero-temporal-bulbar conjunctiva of each eye with a strip of cellulose acetate filter paper and transferred onto a glass slide. Venous blood was drawn at 0 and 5 h after administration of an oral dose of 1000 micrograms of retinol palmitate (relative dose response test). An increase in serum retinol concentration (> or = 20%) in the 5-h value was considered indicative of an inadequate liver store of vitamin A and hence subclinical vitamin A deficiency. Of the 34 children, 26 (76.5%) had moderate to severe protein-energy malnutrition. Only three children (9%) had abnormal conjunctival impression cytology, whereas 23 (68%) had abnormal relative dose response. Even more striking was the finding that only two of the 23 children with abnormal relative dose response had abnormal conjunctival impression cytology. The results suggest that the conjunctival impression cytology test has poor agreement with the relative dose response test results in assessing vitamin A status in young children. If relative dose response is considered an acceptable reference method for assessing vitamin A status, then the conjunctival impression cytology test cannot be considered a valid measure of subclinical vitamin A deficiency in this population.

Zinc supplementation benefits children with acute and persistent diarrhea and prevents pneumonia. Most deaths from vaccine-preventable diseases are from measles and whooping cough; pneumonia is the most common complication of measles and often the proximate cause of related deaths. Objective: We evaluated the effect of zinc supplementation on episodes of illness in children with measles accompanied by pneumonia. Design: In a double-blind, randomized controlled trial, children aged 9 mo-15 y who were admitted to the Infectious Diseases Hospital in Calcutta with clinically severe measles accompanied by pneumonia and who had been ill for ≤ 7 d were randomly assigned to receive zinc (20 mg, in elemental form as acetate, twice daily for 6 d) or a placebo. All patients received standard treatment with antibiotics and an initial 100 000-IU dose of vitamin A (as palmitate) by mouth. Results: Time-to-event analysis using the Cox proportional hazards model (42 in the zinc group and 43 in the placebo group) showed that the time needed for the resolution of fever and tachypnea, the return of appetite, and the achievement of a "much improved" or "cured" status was not different between the 2 groups. A high proportion of children had low serum retinol and zinc concentrations. Improvement in serum zinc and retinol concentrations after 6 d of treatment was not different between the 2 groups. Conclusion: Children with severe measles accompanied by pneumonia treated with antibiotics and vitamin A did not show any additional benefit from also receiving a zinc supplement.

We examined selected indicators of the nutritional status of elderly people attending the Dhaka Hospital of ICDDR,B, Dhaka, Bangladesh. The population constituted of 1,196 individuals (718 men and 478 women), aged 60 to 106 years, who attended the hospital between 1 January 1993 and 31 December 2003. Patients were recruited from a hospital-based systematic sampling, regardless of age and gender, that presented to the facility. Men were heavier, and taller than women were (p < 0.001 for both comparisons). Using MUAC cut-off of < 22 cm for females and < 23 cm for males, at least 50% of the elderly were peripherally wasted (malnourished). Among all the study population, 40% had a BMI within the optimal range (18.5-24.9 kg/m(2)). Using the chronic energy deficiency (CED) classification, at least...

Lipid peroxidation, on the other hand, induces deficiency of many important antioxidative micronutrients. Lipid peroxidations, in terms of TBARS (thiobarbituric acid reactions substances) were measured in a cohort of 10 adult male H. pylon' infected human subjects before and after eradication of this bacterium by a triple therapy regimen using omeprazole (20 mg), amoxicillin (lg) and metronidazole (400 mg) twice a day for two weeks. Presence and absence of H. pylon' were ascertained by the 13C urea breath test (UBT). Total radical antioxidant parameters (TRAP) reflecting the antioxidative protection were also measured. The TBARS (pmol/l) were reduced from 2.99 + 0.61 to 1.16 + 0.19 with concomitant increase of TRAP values (mmol/l) from 1.1 + 0.4 to 1.9 + 0.4. after eradication of H. pylori. These significant (P<O.OOl) changes of oxidant, i.e. lipid peroxidation, and antioxidant (TRAP) status suggest prevalence of oxidative stress in humans due to H. pylon' infection. Since oxidative stress is implicated in many life threatening diseases, results of this preliminary study strongly suggest prospective investigations of the association of H. pylon' with human health disorders.

To our knowledge, this is the first evidence to show the effect of body FM to aggravate toxin-induced infections leading to diarrhea. The overall results suggest further investigations to explore the possible role of body fat in infectious diseases in humans.
