Abstract

ED-71 is a potent analog of active vitamin D, 1,25 (OH) (2)D(3), bearing a hydroxypropoxy substituent at the 2beta-position. In ovariectomized rats, ED-71 prevented the reduction in bone mass and strength of lumber spine without causing hypercalcemia. From those results, it was suggested that ED-71 preferentially enhances bone formation with less effects on intestinal calcium absorption. In osteoporotic patients, oral daily administration of ED-71 (0.25, 0.5, 0.75 and 1.0 microg) for 6 months increased bone mineral density (BMD) at L(2-4) in a dose-dependent manner. ED-71 also exhibited a dose-depend suppression of urinary deoxypyridinoline with no significant reduction in serum osteocalcin. These results demonstrate that ED-71 can effectively increase bone mass without causing hypercalcemia, and suggest that ED-71 can be a promising candidate for the treatment of osteoporosis with prominent effect on bone formation.

[Critical appraisal: combined T3 and T4 replacement therapy is not better than replacement with T4 alone].

Conflicting results have recently been published about the benefits of combined thyroxine (T4) and triiodothyronine (T3) in treating hypothyroid patients. However these studies may have been underpowered to detect differences in psychological well-being specifically related to thyroxine replacement. We conducted a large, double-blind, randomized controlled trial of partial substitution of 50 microg of T4 by 10 microg of T3 (T3) vs placebo (T4 alone - 50 microg of T4 replaced) in 697 hypothyroid patients. Thyroid function showed a rise in the TSH (132%), a fall in Free T4 (35%, P <0.001) and unchanged basal Free T3 levels (P=0.92). At 3 months there was a large (39%) < > improvement in < > defined by the General Health Questionnaire 12 score (GHQ 12) in the control group compared with baseline and this was sustained at 12 months. Differences vs the intervention (T3) group were more modest with improvements in GHQ caseness (OR - 0.61; 95% CI: 0.42, 0.90; P=0.01) and HADS anxiety scores at 3 months (P <0.03) but not GHQ Likert scores, HADS depression, thyroid symptoms or visual analog scales of mood and the initial differences were lost at 12 months. These results may be consistent with a subgroup of patients showing transient improvement following partial substitution with T3 but do not provide conclusive evidence of specific benefit from partial substitution of T4 by T3 in patients on thyroxine replacement. They also emphasize the large and sustained < > that can follow changes in thyroid hormone administration.

[Enhanced BK(Ca) single-channel activities in cerebrovascular smooth muscle cells of simulated microgravity rats.].

The aim of the present study was to investigate the changes in single-channel currents of large conductance calcium-activated potassium channels (BK(Ca) channels) in cerebral vascular smooth muscle cells (VSMCs) of rats after 1-week simulated microgravity. Sprague-Dawley rats were subjected to tail-suspension (SUS) to simulate cardiovascular deconditioning due to microgravity. Cytosolic calcium ([Ca(2+)](i)) was examined by laser-scanning confocal microscopy with calcium-sensitive-dye Fluo-3/AM as fluorescent probe. Single-channel currents of BK(Ca) channels were measured with cell-attached membrane patches bathed in symmetrical high potassium solution. The [Ca(2+)](i)i level was significantly higher in cerebrovascular myocytes of SUS than that of control (CON) rats. The probability of open (Po) and the mean open time (To) of BK(Ca) channels in cerebral VSMCs significantly increased in SUS as compared with CON. However, there were no significant differences in the unitary conductance and mean close time (Tc) between the two groups. The results obtained suggest that both the elevated [Ca(2+)](i) and enhanced single-channel activities of BK(Ca) channels in cerebral VSMCs might be among the electrophysiological mechanisms that mediate the increased vasoreactivity and hypertrophic change in cerebral arteries during adaptation to simulated microgravity in rats.

[Angiotensin-converting enzyme inhibitors potentiate subthreshold preconditioning through NO and mitoK(ATP) channel.].

The aim of the present study was to determine whether angiotensin-converting enzyme inhibitors (ACEI) could contribute to the protective effects of preconditioning, and to explore its underlying mechanism. The Langendorff model of isolated rat heart was used. Cardiac contractility and lactate dehydrogenase (LDH) in the coronary effluent were measured, and infarct area of hearts after 30 min of ischemia followed by 120 min of reperfusion was analyzed. We found that: (1) The subthreshold preconditioning (2 min of ischemia and 10 min of reperfusion), captopril (an ACEI with sulfhydryl groups) or perindoprilate (an ACEI without sulfhydryl groups) alone did not protect the hearts from being injured by 30 min of ischemia and 120 min of reperfusion. (2) However, the combination of captopril or perindoprilate with subthreshold preconditioning could decrease left ventricular end-diastolic pressure (LVEDP), increase left ventricular developed pressure (LVDP) and coronary flow compared with the subthreshold preconditioned group. The combination treatments also inhibited the release of LDH from ischemia/reperfusion hearts, and reduced the infarct area in ischemic heart after 2 h of reperfusion (P<0.05). (3) By using NOS inhibitor L-NAME (100 mumol/L) before combined administration of ACEI with subthreshold preconditioning, the protection effect triggered by the combination treatment was significantly reduced. Pretreatment of the hearts with mitochondrial ATP-sensitive potassium (mitoK(ATP)) channel inhibitor 5-HD (100 mumol/L) also abolished the protection effect (P<0.05). (4) Subthreshold preconditioning, captopril or perindoprilate alone could enhance the NO content in coronary effluent (P<0.05), but the combination of captopril or perindoprilate with subthreshold preconditioning could further augment the NO content compared with the subthreshold preconditioned group (P<0.05). The results indicate that ACEIs with or without sulfhydryl groups may potentiate the subthreshold preconditioning to trigger cardiac protection effect against the ischemia/reperfusion injury. This protection effect in the heart is possibly mediated by the generation of NO and the activation of mitoK(ATP) channel.
