INCREASED HISTAMINE Hi RECEPTOR BLOCKADE BY CHLORPHENIRAMINE IN TRACHEAL CHAINS OF ASTHMATIC GUINEA PIGS
Receptor affinity and drug delivery to the receptor sites could be determinant factors for the increased bronchial responsiveness seen in asthma. Competitive antagonism blockade which is measured as dose ratio-l (DR-I) depends only on these two factors. Therefore, in this study we have examined histamine HI blockade by chlorpheniramine on isolated tracheal chains of asthmatic compared to co...
متن کاملTHE EFFECT OF ASCORBIC ACID ON BLOOD HISTAMINE LEVEL AND DELAYED-TYPE HYPERSENSITIVITY IN GUINEA PIGS
The effect of ascorbic acid on blood histamine level and delayed-type hypersensitivity was studied in thirty male guinea pigs. Animals were sensitized to B.C.G., trichophytin and mallein during the first four weeks. The diet was ad libitum during this period. After this "sensitization period" animals w er e tested intradermally with tuberculin, trichophytin and mallein. The number and diam...
متن کاملComparison of Different 2D and 3D-QSAR Methods on Activity Prediction of Histamine H3 Receptor Antagonists
Histamine H3 receptor subtype has been the target of several recent drug development programs. Quantitative structure-activity relationship (QSAR) methods are used to predict the pharmaceutically relevant properties of drug candidates whenever it is applicable. The aim of this study was to compare the predictive powers of three different QSAR techniques, namely, multiple linear regression ...

متن کاملRole of histamine H3 receptor in glucagon-secreting αTC1.6 cells
Pancreatic α-cells secrete glucagon to maintain energy homeostasis. Although histamine has an important role in energy homeostasis, the expression and function of histamine receptors in pancreatic α-cells remains unknown. We found that the histamine H3 receptor (H3R) was expressed in mouse pancreatic α-cells and αTC1.6 cells, a mouse pancreatic α-cell line. H3R inhibited glucagon secretion from...
