The effect of both isomers of niguldipine, a highly selective alpha 1-adrenoceptor antagonist and dihydropyridine calcium channel blocker, on noradrenaline-stimulated inositol phosphate (IP) accumulation and adenosine 3':5'-cyclic monophosphate (cyclic AMP) potentiation was examined. Both isomers inhibited noradrenaline-stimulated IP accumulation. (+)-Niguldipine was 100 fold more potent than (-)-niguldipine. Potentiation of beta-adrenoceptor-stimulated cyclic AMP by noradrenaline was only partially inhibited by both isomers. The dihydropyridine, israpidine, did not inhibit either second messenger response. This study provides further evidence that the alpha 1-adrenoceptors mediating IP accumulation and cyclic AMP potentiation are different.     

鼻咽癌的癌基因表达与其生长倾向及放射敏感性关系探讨

目的 验证鼻咽癌的癌基因表达与鼻咽癌生长倾向和放射敏感性的关系。方法 检测我院６１例鼻咽癌病人的Ｐ５３，Ｐ２１，ＮＭ２３，ＰＣＮＡ，并分析鼻咽癌病人临床肿瘤生长方式和放射治疗结果。结果 鼻咽癌上行性生长者Ｐ５３、Ｐ２１，ＮＭ２３阳性率较高，而ＰＣＮＡ阳性率较低。
