Effects of ranitidine on contraction and action potentials in normal and potassium depolarized isolated papillary muscles of the guinea pig

The purpose of these experiments was to investigate the possible ionicbases for ranitidine (Ran) in isolated papillary muscles of the guinea pig.Ran,when the concentration was below 300μmol/L,had no influence on contraction ofnormal muscles and only above 0.3 mmol/L,it showed weak negative inotropic ef-fect.The contractile activity elicited by histamine in potassium depolarized mus-cles was depressed by Ran markedly and dose-dependently.The IC_(50) of Ran was0.273μmol/L.This depressant effect was reversed by an elevation of externalCa~(2+)concentration to 7.7mmol/L.The contraction induced by isoproterenol inpotassium depolarized preparations was not altered by Ran.Ran at theconcentrations of 1,10 and 100μmol/L failed to show influences on fast actionpotentials.However,Ran at 0.5μmol/L time-dependently inhibited slow action po-tentials.It is concluded that the ionic mechanism of Ran might be attributed toantagonized H_2 receptor of myocardium which in turn decreases Ca~(2+) inward cur-rent.

Aqueous Extracts of Tribulus terrestris Protects Against Oxidized Low-Density Lipoprotein-Induced Endothelial Dysfunction

Objective:To investigate the role of aqueous extracts of Tribulus terrestris(TT) against oxidized low-density lipoprotein(ox-LDL)-induced human umbilical vein endothelial cells(HUVECs) dysfunction in vitro.Methods:HUVECs were pre-incubated for 60 min with TT(30 and 3 μg/mL respectively) or 10~(-5) mol/L valsartan(as positive controls) and then the injured endothelium model was established by applying 100 μg/mL ox-LDL for 24 h.Cell viability of HUVECs was observed by real-time cell electronic sensing assay and apoptosis rate by Annexin V/PI staining.The cell migration assay was performed with a transwell insert system.Cytoskeleton remodeling was observed by immunofluorescence assay.The content of endothelial nitric oxide synthase(eNOS) was measured by enzyme-linked immunosorbent assay.Intracellular reactive oxygen species(ROS) generation was assessed by immunofluorescence and flow cytometer.Key genes associated with the metabolism of ox-LDL were chosen for quantitative real-time polymerase chain reaction to explore the possible mechanism of TT against oxidized LDL-induced endothelial dysfunction.Results:TT suppressed ox-LDL-induced HUVEC proliferation and apoptosis rates significantly(41.1%and 43.5%after treatment for 3 and 38 h,respectively;P0.05).It also prolonged the HUVEC survival time and postponed the cell's decaying stage(from the 69 th h to over 100 h).According to the immunofluorescence and transwell insert system assay,TT improved the endothelial cytoskeletal network,and vinculin expression and increased cell migration.Additionally,TT regulated of the synthesis of endothelial nitric oxide synthase and generation of intracellular reactive oxygen species(P0.05).Both 30 and 3 μg/mL TT demonstrated similar efficacy to valsartan.TT normalized the increased mRNA expression of PI3Kα and Socs3.It also decreased mRNA expression of Akt1,AMPKα1,JAK2,LepR and STAT3 induced by ox-LDL.The most notable changes were JAK2,LepR,PI3 K α,Socs3 and STAT3.Conclusions:TT demonstrated potential lowering lipid benefits,anti-hypertension and endothelial protective effects.It also suggested that the JAK2/STAT3 and/or PI3K/AKT pathway might be a very important pathway which was involved in the pharmacological mechanism of TT as the vascular protective agent.     

不同类型茶叶对小白鼠体质量的影响

目的：探讨不同类型茶叶对体质量的控制作用,探讨茶叶对肥胖的预防保健作用。方法：将42只体质量超过普通饲料喂养小鼠体质量20％的小鼠做为单纯肥胖模型,随机分为4组,分别为空白对照组12只,红茶喂养组、绿茶喂养组和黑茶喂养组,每组10只,共喂养45 d。实验前后观察小鼠体质量。结果：喂养45 d后,空白对照组小鼠体质量增加了37.49 g,而红茶、绿茶、黑茶组分别增加32.87、33.08、32?53 g,较空白对照组分别减少12.3％、11.7％、13.2％( P<0.05)。结论：长期坚持喂养茶叶可有效地控制生长期小鼠体质量的增长。相对而言,黑茶的效果显著,红茶次之。
