The present study examined the ability of two analogs of human/rat corticotropin-releasing factor (h/rCRF), [Met18, Lys23, Glu27,29,40, Ala32,41, Leu33,36,38] h/rCRF9-41 (alpha-hel CRF9-41) and [D-Phe12, Nle21,38, C alpha MeLeu37] h/rCRF12-41 (D-Phe CRF12-41), to antagonize CRF- and stress-induced behavioral changes in rats. The potency and duration of(More)
Quantitative receptor autoradiography was used to examine the effect of chronic cocaine exposure on the density of alpha1-, alpha2- and beta-adrenergic, 5-HT1A- and 5-HT2-serotonergic, and D1- and D2-dopaminergic receptors in the fetal guinea pig cerebral wall which contained forming motor area of the cerebral cortex. The pregnant guinea pig received two(More)
Previous film autoradiographic studies demonstrated that, during corticogenesis, dopamine receptors of the D1 class are abundant in the embryonic primate cerebral wall. In the present study, we expand these findings by identifying the cellular elements of the fetal occipital cerebral wall expressing D1 and D5 subtypes of the D1 dopamine receptor class. We(More)
BACKGROUND Sutherlandia frutescens (L) R.Br. is one of traditional herbal medicines that formed the basis of primary health care systems since the earliest days and is still widely used. Sutherlandia is prescribed for people with tuberculosis (TB), but is still not known which compound(s) acts against M. tuberculosis and its mode of action. The aim of this(More)
