1. The effect of glyburide (glibenclamide) treatment in vivo on the adipose tissue glycogen synthase activity of type II diabetic rats has been studied. 2. Three week treatment of diabetic animals with glyburide (5 mg/kg orally, in saline) increased adipose glycogen synthase activity and decreased blood glucose levels. 3. These results demonstrate that the sulfonylurea glyburide is capable of exerting direct insulin-like effect on adipose glycogen-synthase activity of type II diabetic rats in vivo. 相似文献

电动汽车是我国新能源战略重点之一,国家电网公司为此积极展开电动汽车充电站的建设。国家电网将按照换电为主、插充为辅,集中充电、统一配送为基本商业模式,加快电动汽车充换电站的布局和建设。不论是插充方式还是集中充电,电动汽车的普及都离不开充电智能化,而BMS与充电桩或其他充电设备的无缝连接正是实现充电智能化的必要条件。文章提出了BMS管理系统与充电桩之间的通信设计方案,利用CANBUS实现BMS管理系统与充电桩的通讯,介绍了CAN通讯的硬件设计和软件设计,并经过与充电桩的反复测试,实现了BMS管理系统与充电桩的通信。 相似文献

In existence for more than 100 years, the schools of medicine and dentistry of Howard University and Meharry Medical College have been responsible for training the majority of African-American physicians and dentists. The dissolution of the doctrine of "separate but equal" has resulted in the acceptance of larger numbers of African-American health professionals to America's medical and dental educational institutions. The University of Tennessee School of Dentistry is a primary example of a formerly segregated institution that has changed its policies and presently possesses a respectable number of African-American dental alumni. In a recent acknowledgment of this fact on Alumni Day, black graduates of this University celebrated and sponsored a program to increase the number of African-American matriculants at the school. 相似文献

The cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channel has been identified in the cardiac muscle of a number of mammalian species, including humans. The goal of this study was to begin quantifying the structural requirements necessary for arylaminobenzoate block of the CFTR channel. The cardiac cAMP-dependent Cl- current (ICl) was measured using the whole-cell arrangement of the patch-clamp technique in guinea pig ventricular myocytes during stimulation of protein kinase A with forskolin. At drug concentrations below the IC50 value for channel block, reduction of ICl by the arylaminobenzoates occurred in a strongly voltage-dependent manner with preferential inhibition of the inward currents. At higher drug concentrations, block of both the inward and outward ICl was observed. Increasing the length of the carbon chain between the benzoate and phenyl rings of the arylaminobenzoates resulted in a marked increase in drug block of the channel, with IC50 values of 47, 17, and 4 microM for 2-benzylamino-5-nitro-benzoic acid, 5-nitro-2-(2-phenylethylamino)-benzoic acid, and 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB), respectively. Increasing the carbon chain length further with the compound 5-nitro-2-(4-phenylbutylamino)-benzoic acid, caused no additional increase in the potency of drug block (IC50 = 4 microM). Inhibition of ICl by the arylaminobenzoates was modulated by the pH of the external solution; increasing the pH from 7.4 to 10.0 greatly weakened NPPB block, whereas decreasing the pH to 6.4 enhanced block. In addition, block of ICl was observed during intracellular dialysis of NPPB, and this action was not affected by raising the external pH. 相似文献
