it demonstrates very low muscle activity during the plank exercise. The role of the ES in the plank ex- ercise is limited as the plank exercise resists body weight and gravity with the anterior surface of the trunk. Despite the weak muscle activity of the ES, the plank exercise can be used to evaluate and strengthen the core muscles, mainly fo- cusing on the transversus abdominis (TrA). Mok et... Objective: This study compared the muscle activities of the erector spinae (ES), the external oblique (EO), and the rectus abdominis (RA) on three different surfaces. The purpose of this study was to determine which surface induces the highest muscle activity during the plank exercises. The information from this study can be used to recommend plank exercises to athletes and patients with weak core muscles. Design: Cross-sectional study. Methods: The subjects include 20 adult males attending S... -

and 2) increased lymphatic pressure in the gut due to different factors. In our dogs, both mechanisms could be implicated. Rupture of intestinal villous lacteals that appeared as “rice-grain” spots in duodenum in our study indicated lymph leakage into the intestinal lumen with other components such as chylomicrons, lymphocytes, and proteins [20,22]. Although some lymph constituents can be... compared to LPE dogs without white spots (p = 0.039). There was a significant correlation between white spots density and lymphatic dilatation histological scores (p = 0.023; ρ = 0.481). These results suggest that the presence of white spots in the duodenal mucosa of dogs is not a finding exclusive for intestinal lymphangiectasia. Low serum protein and albumin concentrations together with lymphatic dilatation seem to be related to the presence of white spots in the duodenal mucosa of LPE dogs. -

developed pressure and claimed that EGCG represents a positive inotropic effect via the nitric oxide pathway [9]. Given the low bioavailability of EGCG, it is unlikely that EGCG had an inotropic effect in our experimental system. In this study, we demonstrated that EGCG (approximately 30 mg EGCG/kg body weight) prevents the development of cardiac hypertrophy induced by pressure overload. It has... Pressure overload diseases, such as valvular stenosis and systemic hypertension, manifest morphologically in patients as cardiac concentric hypertrophy. Prevention of cardiac remodeling due to increased pressure overload is important to reduce morbidity and mortality. Epigallocatechin-3 gallate (EGCG) is a major bioactive polyphenol present in green tea which has been found to be a nitric oxide-mediated vasorelaxant and to be cardioprotective in myocardial ischemia-reperfusion injury. Therefore,... -

Correlation between the regurgitant stroke volume (RSV) obtained by the proximal isovelocity surface area (PISA) method and by quantitative Doppler echocardiography in patients with chronic mitral regurgitation (A). The difference of regurgitant stroke volume (RSV) between the PISA and... present study was performed to determine the accuracy and reproducibility of calculating the mitral regurgitant orifice area with the proximal isovelocity surface area (PISA) method in dogs with experimental mitral regurgitation and in canine patients with chronic mitral insufficiency and to evaluate the effect of general anesthesia on mitral regurgitation. Eight adult, Beagle dogs for experimental mitral regurgitation and 11 small breed dogs with spontaneous mitral regurgitation were used. In 8... -
Regulatory Mechanisms of Angiotensin II on the Na+/H+ Antiport System in Rabbit Renal Proximal Tubule Cells. I. Stimulatory Effects of ANG II on Na+ Uptake

in blood pressure through the actions of the renin-angiotensin system. Indeed the AN G 11 antagorst (Sar-Thr-angiotensin 11) has been shown to reduce blood pressure in this model of hypertension (Cogan， 1990). The role of ANG II in the renal involvement for initiating or maintaining hypertension is certainIy important. ANG 11 has been reported to stimulate the activity of the Na+jH+ anti... to examine signaling pathways of low dose of ANG II on the Na+ uptake of primary cultured rabbit renal proximal tubule cells (PTCs) in hormonally defined serum-free medium. The results were as follows: 1) 10-11 M ANG II has a significant stimulatory effect on growth as compared with control. Alkaline phosphatase exhibited significantly increased activity. However, leucine aminopeptidase and γ-glutamyl transpeptidase activity were not significant as compared with control. In contrast to 10-11 M... -

Thus, this study was undertaken to examine the gene expression of renal renin, angiotensinogen, and AT1 subtypes (AT1A and AT1B) in rats with diabetic nephropathy, and the influences of lipopolysaccharide (LPS)-induced septicemia on the gene expression. Four weeks after streptozotocin (STZ) treatment (55 mg/kg, i.p.), rats were randomly divided into LPS-treated (1.6 mg/kg, i.p.) and... -

was done by gently rubbing the intimal surface with a cotton ball. And successful removal of the en- dothelium was confirmed later by the inability of acetylcholine (10- 6 M) to induce relaxation. Statistical analysis Differences in various parameter were compared by using Student's t-tests procedure. Correlation between blood pressure and endothelium-dependent contraction was analyzed by... pressure was suppressed. 4. In aortic rings from 1K,1C-GBH rats, endothelium-dependent contractions by acetylcholine were augmented as compared with WKY. 5. There is good relationship between the value of blood pressure and magnitude of endothelium-dependent contraction. Thus, it is suggested that increased endothelium-dependent contraction in hypertensive rats may he due to the high blood pressure and endothelium-dependent contraction may not be a cause of the initiation of hypertension in SHR.... -

high pressure (Owens & Reidy, 1985). Endothelial turnover rate has been suggested to indicate endothelial damage or disruption better than visual examination of the endothelial surface (Owens & Reidy, 1985). It could be suggested that the function of damaged and newly developed endo- thelium is depressed and the production of EDRF is decreased, compared with normal endothelium. In contrast... phenylephrine and serotonin between the high pressure-exposed vessels and the low pressure-exposed vessels. However, the endothelium-dependent relaxation to acetylcholine and nitroprusside-induced relaxation showed significant differences between the high pressure-exposed and the low pressure-exposed subclavian arteries. From the above results, we suggest that the contractility of vascular smooth muscle is unchanged by the elevated pressure per se. However, the endothelium-dependent relaxation...
