BACKGROUND: It is known that left ventricular(LV) wall motion is not uniform even in normal heart, and the restoring forces make phase differences between LV wall motion and mitral flow velocity during rapid filling period. METHOD: To investigate the regional nonuniformity and restoring forces in 46 patients with hypertension(HT)(group:normal wall thickiness.n=12,II:LVH with fractional shortening(FS)>25%. n=22. III:FS<25%.n=12). We measured the time intervals from A2 to peak thinning rate point of LV posterior wall(A2-(-)dpw/dt).to mitral flow starting point (IRT).and to peak mitral flow velocity(A2-E) by M-mode and Doppler echocardiography. RESULTS: The noniformity((-)dpW/dt-dL/dt)and phase differance((-)dpw/dt-E) were increased in HT(control:HT.22+/-7.8 vs. 49+/-5.2msec, 63+/-4.5 vs, 86+/-6.2msec, p<0.05 respectively).In group comparison, nonuniformity increased in group II and III(group I: group II, III, 35+/-5.1 vs. 50+/-7.1,70+/-14msec, p<0.05 respectively). but phase difference increased only in group II(groupII: group I, III, 93+/-6.0 vs. 75+/-5.2, 80+/-20msec, p<0.05, respectively). CONCLUSION: We interpreted these data that in HT with hypertrophy or not, the nonuniformity of LV wall motion working on the restoring forces which can be expressed as phase difference between LV wall motion and mitral flow. But in HT with hypertensive heart failure group, no significant changes of phase difference and it's suggest that other mechanism could be also working on early diastolic filling.

BACKGROUND: A regional wall motion nonuniformity and a phase difference between LV posterior wall motion and transmitral flow are present during normal rapid filling period and are thought to be an evidence for involvement of ventricular restoring forces. To assess the role of nonuniformity on diastolic funtional impairment of asymmetric septal hypertrophy(ASH), the time relations between left ventricular regional wall motions and filling velocity were studied. METHOD: We measured the time intervals from A2 to peak rate of LV posterior wall(short axis) thinning(A2-(-)dpw/dt), peak rate of medial mitral annulus (long axis dimension) lengthening(A2-dL/dt) and peak mitral flow(A2-E) by M-mode and Doppler echocardiography. Result: In ASH patients, A2-(-)dpw/dt(106+/-6msec, mean SE) and the regional wall motion nonuniformity((-)dpw/dt-dL/dt, 89+/-11msec, mean SE) were increased significantly when compared with normal control values(88+/-4, 28+/-5msec, mean SE, p<0.01,respectively).In normal controls, peak mitral flow velocity lagged peak rate of regional wall motion, so the phase differences were present((-)dpw/dt-E :71+/-8msec, dL/dt-E:44+/-6msec). In ASH patients, (-)dpw/dt-E was present(90+/-16msec) but dL/dt-E was not present or reversed(-21+/-18 msec). So these chacteristic phase differences were disturbed. CONCLUSION: These data suggested that the relaxation nonuniformity of regional wall motion in ASH may act as an energy dissipating factor of restoring forces during rapid filling period.

BACKGROUND: Sex steroid hormones are believed to play an important role in the genesis and growth of uterine myoma. Several studies suggest a possible role of insulin-like growth factor(IGF) as a mediator of estradiol in uterine myama. We have recently demonstrated that some IGF binding proteins(IGFRPs) messenger ribonucleic acid(mRNA) expressions in myoma are dependent on the in vivo esttogen status. The purposes of this study are to evaluate the in vitro effects of sex steroid hormones including estrogen on the IGFBPs gene expression in tissues from uterine myoma and adjacent normal myometrium. METHODS: Tissues from myoma and adjacent normal myometrium of patients with uterine myoma during early proliferative phase of menstrual cycle were cultured in the absence(control) and presence of 17b-estradiol(10M/L) or/and progesterone(10M/L) for 3 days. The IGFBPs mRNA expressions in these explants were analyzed by Nothern blot using specific human complementary deoxyribonucleic acid(cDNA) probes. RESULTS: The addition of 17b-estradiol, progesterone alone and in combination to conditioned media of explants from myoma and adjacent normal myornetrium did not result in any changes in the expression of IGFBP-2, IGFBP-4, IGFBP-5, and IGFBP-6 mRNA. With progesterone addtion, lGFBP-3 rnRNA expression was significantly reduced in myoma explant but not in adjacent ncemal myometrium explant. There was no significant change in the IGFBP-3 mRNA expression with 17b-estradiol and with the combination of both 17b-estradiol and progesterone. CONCLUSION: 17b-estradiol does not affect IGFBPs gene expression in the myoma and adjacent normal myometrium explant regardless of the presence of progesterone in vitro. However progesterone alone induces a decrease in IGFBP-3 synthesis in myoma explant.
