Note
The pioneering work of Bergmann (1949) on antibacterial agents from marine organisms has led to major research effortsover the past two decades to discover cures from the sea forhuman diseases. A more vigorous effort has been launched by several groups during the past five years, culminating in a recentlyexpanded effort by the National Cancer Institute for invitro screening of marine organisms against a large number ofhuman cancers and viruses.
