Research priorities for tobacco control in developing countries: a regional approach to a global consultative process.

Objective: To develop regional tobacco control research agendas for developing countries through a consultative process.

Methods: Research for International Tobacco Control, located at the International Development Research Centre in Ottawa, Canada, convened three regional meetings for Latin America and the Caribbean, South and Southeast Asia, and Eastern, Central and Southern Africa. Participation by researchers, policymakers, and advocates from a wide range of disciplines ensured an accurate representation of regional issues.

The development and implementation of a revised municipal bylaw to control environmental tobacco smoke.

A bylaw to regulate the contamination of the environment by tobacco smoke was introduced in the Capital Regional District, Victoria, British Columbia as of January 1st, 1991. This smoking control bylaw rigorously limits smoking in all public premises and restricts size, ventilation and location of designated smoking areas. As of January 1st, 1992 all workplaces in this area have become completely smoke-free.

Gel-filtered human platelets. Ultrastructure, function, and role of proteins in inhibition of aggregation by aspirin.

Gel filtration of human platelet-rich plasma (PRP) on columns of Sepharose 2B removed at least 99.85% of the plasma proteins from platelets when a column 10 cm in height was used and a plasma volume 11 to 14% of the gel-bed volume was applied. ADP and ATP levels in gel-filtered platelets (GFP) were not significantly different from those in PRP.

Ultrastructure of platelets in Bernard-Soulier syndrome.

The platelets of a patient with the Bernard-Soulier syndrome were studied by electron microscopy. The main abnormalities were the presence of giant and often round platelets, hypertrophic and frequently widely dilated open canalicular system, disorganized microtubules, and platelets with sparse or absent granulation. Although well defined, these ultrastructural morphologic aberrations are not considered diagnostic or pathognomonic of the syndrome.
