The effects of dimethylsulfoxide (DMSO) upon the topical absorption of vasopressin and adrenocorticotropin (corticotropin) in the rat and melanocyte stimulating hormone (MSH) in the frog were investigated. At a dose approximately 20,000 times that used intravenously, vasopressin absorption was slightly increased in one third of the rats by the application of DMSO, while corticotropin absorption was unaffected. The topical absorption of MSH in the frog was increased by DMSO in three of five experiments at a dose of MSH several hundred times that used in dorsal lymph sac injection. The small increase in topical absorption of these hormones seen in some animals after the application of DMSO, therefore, required extremely large doses.

WE have recently found that the decrease of ascorbic acid concentration of rats' adrenals due to epinephrine is smaller in rats to which pituitrin has been administered and in dehydrated rats than in normal rats1. This suggests that the posterior pituitary hormone depresses the adrenal cortical activity. The questions arise, whether the posterior pituitary hormone acts directly on the adrenal or indirectly through the depression of the anterior pituitary secretion, and which fraction of the posterior pituitary hormone, pressor or oxytocic, is responsible for this effect. The present work was undertaken to clarify these points.

507. MSH Activity in Rat Pituitaries After Pinealectomy.∗†
- Author
-
Kastin, Abba J., Redding, Tommie W., and Schally, Andrew V.
- Abstract
Pinealectomy resulted in elevation of the MSH content of the pituitary glands of albino rats. This increased level of pituitary MSH persisted for several weeks in 9-week-old rats, but for only a few days in 3-week-old rats.The authors appreciate the expert technical assistance of Mrs. Lynn Barrett and Mrs. Sharon Viosca. We also thank Dr. Akira Arimura and Dr. Edward B. Ferguson, Jr., for their assistance.

The recent discovery of EPPNB occupation at Tell Ain el-Kerkh (ca 9 400-9 200 uncal. BP) in northwest Syria provides a new perspective of the early stage of Neolithisation in the north Levant. The archaeological evidence from Kerkh shows first that the earliest Neolithic occupation in northwest Syria goes back to the EPPNB period and revises the generally accepted hypothesis that the Neolithisation in this region started in the LPPNB. In addition, the narrow naviform cores and Aswad points evidenced at Kerkh appear to be chronological markers of this period and imply the existence of other earlier PPNB sites in northwest Syria. When comparing the subsistence economy and the chipped stone industry of Kerkh with those of other contemporary sites, regional variations between the EPPNB sites become clear and possibly indicate the importance of local traditions in the development of the PPNB cultural horizon. Discovery of an EPPNB site in northwest Syria is also interesting in considering the origin of Cypriot PPN culture, but at the moment direct relationships between Kerkh and Cypriot PPN sites are rare., Au nord-ouest de la Syrie, la découverte d’occupations du niveau du PPNB ancien à Tell Ain el-Kerkh (ca 9 400-9 200 BP) fournit une perspective nouvelle sur la première étape de la néolithisation au Levant nord. Les données archéologiques de Kerkh montrent pour la première fois que l’installation néolithique la plus ancienne remonterait au PPNB ancien. Ceci modifie l’hypothèse généralement acceptée que, dans cette région, la néolithisation a commencé à partir du PPNB récent. En effet, les nucléus naviformes très étroits et les pointes d’Aswad trouvés à Kerkh seraient des marqueurs chronologiques de cette période. Leur présence sur d’autres sites suggère l’existence de sites contemporains dans le nord-ouest de la Syrie. Lorsque l’on compare l’économie de subsistance et les industries lithiques de Kerkh avec celles des autres sites contemporains, une variation régionale entre les sites PPNB ancien apparaît plus clairement. Cela peut suggérer également que des traditions locales se seraient largement développées sur l’horizon culturel du PPNB. Cette découverte d’un site PPNB ancien en Syrie du nord-ouest apporte des éléments permettant de nourrir la réflexion sur l’origine de la culture PPN à Chypre: cependant, pour l’instant les relations claires entre Kerkh et les sites PPN chypriotes restent rares., Tsuneki Akira,Arimura Makoto,Maeda Osamu,Tanno Ken'ichi,Anezaki TomokoTsuneki Akira, Arimura Makoto, Maeda Osamu, Tanno Ken'ichi, Anezaki Tomoko.

509. Editorial [Hot topic:VIP and PACAP: Novel Approaches to Brain Functions and Neuroprotection (Executive Guest Editors: Seiji Shioda and Illana Gozes)]

- Abstract
In 1970 and 1972, Sami Said and Victor Mutt identified and isolated “vasoactive intestinal polypeptide” (VIP) from porcine intestine based on its ability to increase peripheral blood flow and decrease arterial blood pressure in dogs [1,2]. In 1989 Akira Arimura and his colleagues isolated pituitary adenylate cyclase-activating polypeptide (PACAP) based on its ability to stimulate the production of cyclic AMP in rat pituitary cells [3]. VIP and PACAP serve as hormones, transmitters, modulators, and tropic factors, which act in both the central (CNS) and the peripheral nervous systems (PNS) through specific high-affinity receptors. Their actions are versatile and diverged within an organism as pleiotropic neuropeptides. In 1999, the laboratory of Illana Gozes in collaboration with the laboratory of Douglas Brenneman discovered the VIP-regulated activity-dependent neuroprotective protein (ADNP) and identified an ADNP derived peptide NAP (NAPVISPQ) [4]. NAP (davunetide) is now being developed as a drug candidate in progressive supreanuclear palsy, a rare fatal disease often misdiagnosed as Parkinson disease [5]. The various VIP and PACAP receptors are differentially expressed in discrete areas in the CNS and PNS as well as other peripheral organs and tissues. VIP and PACAP receptors have been identified in numerous tissues, and three different types are discerned. Two of these (VPAC1 and VPAC2) bind PACAP and VIP with similar high affinity. The third type, PAC1 is a PACAP specific receptor. PAC1 binds PACAP with high affinity and usually interacts with VIP only at high VIP concentration. PAC1 is also unique because it exists in at least thirteen different forms derived forms derived by alternate mRNA splicing. These different splice variants regulate receptor ligand affinity and specificity, and coupling to adenylte cylase and phosopholipase C pathways [6]. PAC1, VPAC1 and VPAC2 have been identified not only in the nervous system but in endocrine glands such as the pituitary, the thyroid, the gonads and the adrenal, as well as in the gastrointestinal tract, liver, pancreas, respiratory system, cardiovascular system, immune system, bones and tumor cells. Although a very large number of functions are described, it is likely that new roles for PACAP and VIP will be discovered followed by therapeutic applications. PACAP, VIP and its related peptides are shown to play very important roles in controlling homeostasis throughout the animal kingdom from sea squirt to humans. Both VIP and PACAP appear to play important, but distinct roles in circadian rhythms, nerve injury, ischemia and excitotoxicity, pain, epilepsy, schizophrenia, Alzheimers disease, emotional and psychomotor behavior, neurodevelopment and immune response [6, 7, 8, 9, 10, 11, 12, 13, 14). In this special issue, leading international experts discuss most relevant topics on novel potential targets for VIP, PACAP and NAP. The special issue will strongly contribute to progress not only in basic research in this field but also in translational research and it may encourage moving forward toward human translational research. Finally, we would like to thank all the contributors to this special issue for their excellent participation.
