ABSTRACT The characteristics and nature of the effect of growth hormone on the incorporation of radio-sulfate into the costal cartilage of hypophysectomized rats has been studied. The time-response studies indicate that a reliable estimation of growth hormone activity can be ascertained within a 24 hour period, and a reproducible dose-related response can be obtained at dosage levels ranging from 12-48 μg. Growth hormone stimulates the synthesis of organic sulfates and accumulation of inorganic sulfates within 48 hours.

This chapter examines the politics of the currency in West Africa from the beginning of the twentieth century. A public series of debates over the nature of the currency occurred in West Africa during both the colonial and independence periods. Since 1983, West African countries have been pioneers in Africa in developing new strategies to combat overvaluation of the currency and reduce the control of government over the currency supply. The chapter charts the evolution of West African currencies as boundaries and explores their relationship to state consolidation. It shows that leaders in African capitals managed to make the units they ruled increasingly distinct from the international and regional economies, but the greater salience of the currency did not end up promoting state consolidation. Rather, winning the ability to determine the value of the currency led to a series of disastrous decisions that severely weakened the states themselves.
