During the first countrywide outbreak of dengue hemorrhagic fever in Bangladesh, we conducted surveillance for dengue at a hospital in Dhaka. Of 176 patients, primarily adults, found positive for dengue, 60.2% had dengue fever, 39.2% dengue hemorrhagic fever, and 0.6% dengue shock syndrome. The Dengue virus 3 serotype was detected in eight patients.

Human DNA helicase IV, a novel enzyme, was purified to homogeneity from HeLa cells and characterized. The activity was measured by assaying the unwinding of 32P labeled 17-mer annealed to M13 ss DNA. From 440g of HeLa cells we obtained 0.31 mg of pure protein. Helicase IV was free of DNA topoisomerases, DNA ligase and nuclease activities. The apparent(More)
Dopoamine-β-hydroxylase (DBH) is a catecholamine-synthesizing enzyme which catalyzes the formation of norepinephrine from dopamine. Fifty nine Long-Evans rats of 1 week-old were used to grow on normal diets in 7 different developmental stages, viz., 15 rats in 1 week-old group, 9 rats in 2 weeks-old group, and the remaining 35 rats were divided equally into(More)
Dopamine-β-hydroxylase (DBH) is a neurotransmitter (catecholamine)-mediating enzyme, which catalyzes the formation of norepinephrine from dopamine. The levels of DBH activity, its coenzyme (ascorbic acid) and cofactor (Cu(++)) and other biochemical parameters were measured in the serum of 32 arsenicosis patients of Bangladesh at three different age groups,(More)
