Recently, considerable attention has been focused on studies of membrane structure and function--involvement of cell surface components in intercellular interaction, in translocation of ligands and receptors across cell membranes, and in the immunological properties of cells and gene expression and regulation. These investigations have led to the development of powerful technical tools which can be of immense value in the study of animal and human reproduction. The investigations of problems such as gamete interaction, fertilization, embryo implantation, and development have reached a stage where further meaningful progress in their understanding does not seem likely unless the conventional ...
Our understanding of the functional mechanisms relating dopamine activity to normal and abnormal behavior has been turned "upside-down" by the recent developments described in the chapters of this volume. Heretofore, it was generally agreed that all of the pharmacological and behavioral properties ascribed to dopamine systems were mediated via activation or inhibition of the subtype of dopamine receptors termed D2. The properties of these receptors were first characterized in 1975 following their identification by receptor binding techniques utilizing 3H-butyrophenones, potent antipsychotic drugs, used in the treatment of schizophrenia. Although another subtype of dopamine receptor had alrea...
Human epilepsy is a major public health problem affecting approximately 2 persons per 1000. It is particularly frequent in ohildren where convul sions may lead to brain damage and subsequent seizure activity in adulthood. Temporal lobe epilepsy (synonyms include limbic epilepsy. psychomotor epilepsy and complex partial epilepsy) is the most devastating form of epilepsy in the adult population since: a) it is often extremely resistant to currently available anticonvulsant drugs (i.e •• it is more resistant than tonico-clonic or grand mal seizures) and b) it includes loss of consciousness. thereby limiting performance of many normal functions and leaving the individual susceptible to bodil...

Rapid advances have taken place in various aspects of reproductive biology during the last decade. These advances have centered around several organ systems that comprise the reproductive system and encompass molecular events and structure-function relationships. It becomes important to review these advances in knowledge, at periodic intervals, with respect to feedback systems and regulatory loops that control reproductive processes in vivo. Towards this end, a workshop entitled "Functional Correlates of Hormone Receptors in Reproduction" sponsored by the National Institute of Child Health and Human Development and the Reproductive Biology Study Section of the Division of Research Grants, Na...
