PIP: A review of population trends in northeastern Brazil is presented for the period from 1980 to the present, and estimated up to 2005. The analysis is undertaken separately for each of the region's 127 micro-regions. Prospects for demographic aging and the concentration of the population in the coastal regions are assessed.

Different formulations of Trivalent Oral Poliomyelitis Vaccine were tested, in order to obtain better thermostability, reduce corrosion of machinery and improve production costs. Magnesium chloride, sucrose, arginine and 199-Hank's medium were used in the formulations. The most appropriate formulation was a mixture of MgCl2 and arginine, which was highly thermostable, and had low production costs.

Magnesium chloride, sucrose, arginine and 199-Hank's medium were used in the formulations. The most appropriate formulation was a mixture of MgCl2 and arginine, which was highly thermostable, and had low production costs. The low corrosive formulation was rejected, due to low thermostability on storage
