4.Effects of E 4031 on isolated cardiac function and resting Ca2+ level of myocardial cells from rats with chronic heart failure.
Chinese Journal of Applied Physiology 2014;30(4):364-367
OBJECTIVETo investigate the effects of E 4031, a sodium calcium exchanger (NCX) agonist, on the isolated cardiac function and resting Ca2+ level in myocardial cells from rats with chronic heart failure.
METHODSRats chronic heart failure model was established by abdominal aorta coarctation with; Isolated heart perfusion by Langendorff apparatus was used to detect heart function and the effects of E 4031 on haemodynamic indexes; Myocardial cells of rats in the model group were extracted quickly and co-incubated with calcium fluorescent indicator fluo3/AM and the impact of E 4031 on the fluorescence intensity in myocardial cells were evaluated by confocal microscopy.
RESULTSHeart function of rats in the model group detected by Langendorff perfusion was significantly reduced after 12 weeks, E 4031 at 10 micromol/L could improve their left ventricular developed pressure(LVDP) and systolic / diastolic maximum rate (+/- dp/dtmax). Compared with the control and sham operation groups, the resting Ca2+ fluorescence intensity of the myocardial cells of rats in model group was at a higher level and went through a process of transient rise and drop, then stably remaining at a low level after co-incubated with 10 micromol/L E 4031.
CONCLUSIONE 4031 can improve the isolated heart function of rats with chronic heart failure, which may be associated with its enhancing the activity of NCX in the myocardial cell membrane and stabilizing intracellular Ca2+ level.

BACKGROUND:Studies on the inhibitory mechanism of Avastin for early diabetic retinopathy rats are mostly confined to the vascular endothelial growth factor, while connective tissue growth factor and pigment epithelium-derived factor also play an important role in the disease.
OBJECTIVE:To evaluate the changed cytokines of aqueous humor and significance of Avastin intravitreous injection in early diabetic retinopathy rats.
METHODS:Rat models of early diabetic retinopathy were established by inducing with streptozotocin for 10 weeks. Avastin (1.25 mg and 2.5 mg) and physiological saline were injected in the vitreous space.
RESULTS AND CONCLUSION:Enzyme linked immunosorbent assay results revealed that compared with the physiological saline injection group, mass concentration of vascular endothelial growth factor was reduced, mass concentrations of pigment epithelium-derived factor and connective tissue growth factor was increased in aqueous humor of the two Avastin injection groups (P<0.05), but no significant difference in concentration of above cytokines was detected between the two groups (P>0.05). Results verified that Avastin intravitreous injection decreased vascular endothelial growth factor levels, decreased pigment epithelium-derived factor mass concentration and increased connective tissue growth factor levels in rat models of early diabetic retinopathy.
