1. Effects of NS-1619, an opener of large conductance Ca2+-activated K+ (BK) channel, on intracellular Ca2+ concentration ([Ca2+]i) and membrane potential were examined in single myocytes freshly isolated from porcine coronary artery. 2. Under current clamp mode, the application of 1-30 microM NS-1619 hyperpolarized the membrane in concentration-dependent manner. The NS-1619-induced hyperpolarization was abolished by the presence of 100 nM iberiotoxin. 3. Application of 1-10 microM NS-1619 hyperpolarized the membrane by approximately 6 mV or less but did not change significantly the [Ca2+]i. When membrane hyperpolarization of 12 mV or so was caused by 30 microM NS-1619, [Ca2+]i was unexpectedly increased by approximately 200 nM. This increase in [Ca2+]i and the concomitant outward current activation were also observed under voltage-clamp at holding potential of -40 mV. 4. The increase in [Ca2+]i by 30 microM NS-1619 occurred mainly in peripheral regions than in the centre of the myocytes. The removal of extracellular Ca2+ affected neither the membrane hyperpolarization nor the increase in [Ca2+]i. 5. In the presence of 10 mM caffeine and 10 microM ryanodine, the increase in [Ca2+]i by 30 microM NS-1619 was not observed and the membrane hyperpolarization was reduced to approximately 67% of the control. 6. These results indicate that the opening of BK channels by NS-1619 at 30 microM, which is the most frequently used concentration of this agent, is partly due to Ca2+ release from caffeine/ryanodine-sensitive intracellular storage sites but is mainly due to the direct activation of the channels.

Escape deficits induced by inescapable shock and metabolic stress are reversed by adenosine receptor antagonists.

We examined the relationship between metabolic stress, brain adenosine regulation, and the learned helplessness effect in four experiments in rats. Glucoprivation and metabolic inhibition were induced by treating previously restrained (nonshocked) rats with 2-deoxy-D-glucose (2DG) shortly before escape testing. Experiment 1 demonstrated that 2-deoxy-D-glucose impairs escape performance in a dose-dependent manner. Experiment 2 showed that 2-deoxy-D-glucose and shock induced escape deficits are completely reversed by peripheral administration of the adenosine receptor antagonist caffeine. This result indicates that both inescapable shock and 2-deoxy-D-glucose result in compensatory adenosine regulation which, in turn, mediates the behavioral impairment. Experiment 3 determined that 8-[p-sulfophenyl]-theophylline, a peripheral adenosine receptor antagonist, fails to reverse the escape deficit resulting from metabolic stress, whereas centrally acting theophylline does. Experiment 4 showed that the behavioral impairments from both 2-deoxy-D-glucose and inescapable shock are reversed by intracranial ventricular (icv) caffeine treatment. The results of Experiments 3 and 4 indicate that the enhanced adenosine regulation and the ensuing performance deficit resulting from 2-deoxy-D-glucose treatment occurred in the central nervous system. These data are discussed in terms of the metabolic demands of neuronal over-activation during escape testing in inescapably shocked rats and the loss of normal behavioral function due to compensatory adenosine regulation in the brain.

We have investigated the endothelium-independent vasorelaxant effect of the new flavonoid dioclein (5,2',5'-trihydroxy-6-7-dimethoxyflavanone) in the rat aorta. In endothelium-denuded vessels, dioclein induced a concentration-dependent relaxation of aortic rings precontracted with noradrenaline (IC50 = 3.5+/-0.89 x 10(-4) M and KCl (IC50 = 5.2+/-1.2 x 10(-4) M). In the absence of extracellular calcium, dioclein reduced the contraction induced by noradrenaline (maximal reduction approximately 33%) but not that induced by caffeine. Dioclein also produced a concentration-dependent inhibition of the sustained contractions induced by the phorbol ester 12-O-tetradecanoyl phorbol-13-acetate in normal (IC50 = 4.0+/-0.2 x 10(-4) M) and Ca2+-free solution (IC50 = 4.0+/-0.3 x 10(-4) M). The results indicate that the endothelium-independent vasorelaxant effect of dioclein may be explained by inhibition of contractions dependent on activation of protein kinase C, voltage-dependent Ca2+ influx and on the release of intracellular Ca2+ stores sensitive to noradrenaline.

Loss of hair changes the appearance of a person, and the identity of the person in social context to a certain extent.
Hair growth is a complex biological process, which has not yet been completely understood. A multitude of therapeutic measures, including drugs, surgery, and suppelements have been made available, and used. However, due to the diversity of the problems underlying hair loss, there is no single solution for all hair loss cases. Most of chemical drugs and hair transplantation surgeries are not free from varying degrees of undesirable side effects on health.
Hair Million is an alternative solution to hair loss problems. Albeit only anecdotally, it has demonstrated efficacy in
the improvement for age-related hair thinning and hair loss for a significant fraction of people who take it
as recommended. We do not know the mechanisms of action as to how Hair Million works to help stop hair loss, and promote hair growth. We only know by
anecdotal observations. There has been no clinical trials nor placebo controlled statistical analysis.
DHEA is a natural hormone, and it is produced in our body by the adrenal glands.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
