Effects of blood sugar level on rat transient focal brain ischemia consecutively observed by diffusion-weighted EPI and (1)H echo planar spectroscopic imaging.

The effects of blood sugar level on transient focal brain ischemia were examined by consecutive diffusion-weighted EPI and (1)H echo planar spectroscopic imaging. A remote-controlled rat intraluminal suture middle cerebral artery occlusion (MCAO) model was prepared. Animals were divided into three experimental groups: control, 1 g/kg, and 2 g/kg glucose groups (n = 6 for each). Saline or glucose was infused intraperitoneally 30 min prior to MCAO. The glucose-loaded groups showed increased lactate accumulation and marked decreases in average diffusion coefficient in the ischemic region during 40-min MCAO. These changes were correlated with blood sugar levels at the onset of MCAO. After reperfusion, all rats in the control and 1 g/kg groups recovered from the ischemic changes, but three rats with marked hyperglycemia in the 2 g/kg group showed irreversible changes. The adverse effects of hyperglycemia on transient focal brain ischemia were clearly demonstrated by sequential 2D images. Magn Reson Med 42:895-902, 1999.     

Serial change in123I-MIBG myocardial scintigraphy in non-insulin-dependent diabetes mellitus

PURPOSE: We performed 123I-MIBG (MIBG) myocardial scintigraphy twice in patients with non-insulin-dependent diabetes mellitus (NIDDM) to investigate whether MIBG distribution was improved by pertinent clinical control. To determine the influential factors for MIBG distribution, we investigated the association between various clinical parameters and the serial change in MIBG uptake parameters. PATIENTS AND METHODS: Twenty NIDDM patients with no cardiac disorders were evaluated. Planar images were taken at 30 minutes (early) and 3 hours (delayed) after MIBG injection. The heart-to-upper-mediastinum uptake ratio (H/M) and washout ratio (WR) were calculated as parameters for estimating cardiac sympathetic function. Patients were divided into two groups, eight in the improved group and twelve in the unimproved group, according to the serial change in H/M. The mean interval between the baseline and the follow up study was 2.1 +/- 0.6 year. Differences between the means of the laboratory data in patients in both groups were compared for the baseline and the follow up study by using the paired t-test. As a means of determining the influential factors for a serial change of MIBG uptake, Fisher's exact test was performed to evaluate the association between the serial change in cardiac MIBG parameters and changes in other clinical parameters, such as blood sugar (BS) control, BS control method (insulin therapy), serum cholesterol control, and severity of diabetic complications. We also analyzed the association between the changes in CV(R-R) (coefficient variance of R-R intervals at rest ECG) or NCV (velocity of posterior tibial nerve) and those of other clinical parameters. Associations among these neurological parameters (MIBG parameters, CV(R-R) and NCV) were also analyzed. RESULTS: Paired t-tests showed a significant decrease in fasting blood sugar and fructosamine in the improved group in the follow up study compared to those in the baseline study. Nevertheless, Fisher's exact test showed no significant association between FBS, HbA1C, fructosamine and the improvement in cardiac MIBG uptake. The only significant association was observed between the serial change in H/M and the BS-control method (insulin therapy). Within the neurological parameters, a significant association was noted between the serial changes in H/M and CV(R-R). CONCLUSION: Although BS control was likely to be an important factor, it did not always ameliorate cardiac MIBG uptake. Based on the significant association between the BS-control method (insulin therapy) and MIBG uptake change, the severity of diabetes mellitus was likely to be a more influential factor. It was suggested that cardiac MIBG uptake could improve within the mild stage if controlled by diet therapy or an oral hypoglycemic agent in NIDDM.     

急性运动对肥胖大鼠下丘脑ghrelin和obestatin的影响

目的:初步探讨一次性跑台运动影响肥胖大鼠摄食的神经内分泌机制。方法:10周成功建模营养性肥胖SD大鼠46只,分为对照组(C)和运动后即刻组(E0)、1小时组(E1)、3小时组(E3)、12小时组(E12)和24小时组(E24)。各运动组大鼠在专用电动跑台上进行一次性运动,跑台坡度5%,速度20m/min,时间为40min。分别于运动后即刻、1h、3h、12h和24h观察大鼠摄食量、血糖、血脂指标;采用放射免疫法测试血浆和下丘脑ghrelin和obestatin蛋白表达,RT-PCR方法测试下丘脑ghrelin受体GHSR-1α、obestatin假定受体GPR-39的基因表达。结果:一次性跑台运动后,与对照组相比,E1、E3、E12和E24组大鼠摄食量下降,血糖和血脂也有不同程度的下降趋势,其中E1组血糖和E12组血脂下降显著;与对照组比较,运动后不同时间段大鼠血浆ghrelin和obestatin无明显变化,而运动后即刻下丘脑ghrelin和obestatin显著下降(P<0.01),在12h和24h又明显上升(P<0.01);与对照组相比,运动后各组下丘脑GHSR-1α基因表达无明显差异,且未见下丘脑GPR-39基因表达。结论:Ghrelin影响大鼠摄食和能量代谢调节可能是通过下丘脑中枢机制,而与外周血ghrelin无关。     

Use of iodine-123 metaiodobenzylguanidine scintigraphy to assess cardiac sympathetic denervation and the impact of hypertension in patients with non-insulin-dependent diabetes mellitus.

The objectives of this clinical study using iodine-123 metaiodobenzylguanidine (MIBG) scintigraphy were (a) to evaluate cardiac sympathetic denervation in non-insulin-dependent diabetes mellitus (NIDDM) patients with and without hypertension and (b) to investigate the relation between cardiac sympathetic denervation and prognosis in NIDDM patients. We compared clinical characteristics and MIBG data [heart to mediastinum (H/M) ratio and % washout rate (WR)] in a control group and NIDDM patients with and without hypertension. MIBG scintigraphy was performed in 11 controls and 82 NIDDM patients without overt cardiovascular disease except for hypertension (systolic blood pressure >/=140 and/or diastolic blood pressure >/=90 mmHg). After MIBG examination, blood pressure was measured regularly in all NIDDM patients. There were significant differences between 65 normotensive and 17 hypertensive NIDDM patients with respect to age (55+/-11 vs 63+/-12 years, respectively, P<0.05), prevalence of diabetic retinopathy (12% vs 35%, respectively, P<0.05) and systolic blood pressure (120+/-12 vs 145+/-16 mmHg, respectively, P<0.001). The H/M ratio in hypertensive NIDDM patients was significantly lower than in the control group (1. 81+/-0.29 vs 2.27+/-0.20, respectively, P<0.01). During the follow-up period (18+/- 12 months), 17 NIDDM patients newly developed hypertension after MIBG examination. There were no significant differences in their clinical characteristics compared with persistently normotensive or hypertensive NIDDM patients. %WR in patients with new onset hypertension was significantly higher than in the control group (30.88%+/-16.87% vs 12.89%+/-11.94%, respectively, P<0.05). Moreover, in these patients %WR correlated with duration from the date of MIBG scintigraphy to the onset of hypertension (r=-0.512, P<0.05). Five NIDDM patients died during the follow-up period (four newly hypertensive patients and one normotensive patient). There were significant statistical differences between the control group and non-survivors in terms of age (54+/-11 vs 73+/-11 years, respectively, P<0.01), H/M ratio (2. 27+/- 0.20 vs 1.64+/-0.36, respectively, P<0.01) and %WR (12. 89%+/-11.94% vs 42.52%+/-22.39%, respectively, P<0.01). In conclusion, cardiac sympathetic denervation using MIBG scintigraphy observed in hypertensive NIDDM patients, and was more profound in non-survivors. MIBG scintigraphy proved useful for the evaluation of NIDDM patients with new onset hypertension, and it was found that NIDDM patients with abnormalities on MIBG scintigraphy needed to be observe carefully.

Prognostic value of cardiac I-123 metaiodobenzylguanidine imaging in patients with non-insulin-dependent diabetes mellitus

BACKGROUND: 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy is a useful tool for diagnosing cardiac autonomic neuropathy (CAN) in non-insulin-dependent diabetes mellitus (NIDDM). However, the long-term prognostic value for cardiac events or mortality in NIDDM has not been clarified. METHODS AND RESULTS: We investigated the long-term prognostic value of cardiac MIBG imaging for both cardiac event and mortality owing to a variety of causes of death in NIDDM. 144 NIDDM patients were analyzed retrospectively with the end-points of a cardiac event and various causes of mortality. The heart-to-mediastinum uptake ratio on the delayed image (H/M [d]) was obtained from anterior planar imaging. The mean follow-up period was 7.2+/-3.2 years. Seventeen patients had a cardiac event onset and 7 patients died during observation. During the same observation course, 16 patients died, including some who died of cardiac event. Both multivariate and univariate analyses revealed that decreased H/M (d) (<1.7) was the independent predictor of long-term mortality for a variety of causes of death. Although the value of H/M (d) was not a significant prognostic factor for predicting a cardiac event, CAN, diagnosed by a combination of H/M (d) and coefficient variance of RR interval, was an independent predictor for the cardiac event in NIDDM. CONCLUSION: MIBG myocardial scintigraphy was useful for predicting cardiac events and long-term mortality in NIDDM.
