Article: A pilot study on effectiveness of music therapy in hospice in Japan.
[show abstract] [hide abstract]
ABSTRACT: This study aims at determining the effectiveness of music therapy in a hospice setting. We employed the salivary cortisol level, which is widely used to measure stress level, as an objective and physical indicator and the Mood Inventory, which measures mood change, as the subjective and psychological indicators. Though many preceding studies have demonstrated that listening to music lowers cortisol levels and reduces stress, no study seems to have included hospice patients. This study measured, with the consent of 10 hospice inpatients, their salivary cortisol levels. Individual interviews, according to the Mood Inventory, were conducted before and after a small-group session. Since all the participants had terminal cancer, the 40-minute live session of songs of seasons and the participants' requests was given in a mostly passive manner considering their physical strength. Results showed significant lowering of salivary cortisol levels after the therapy session. As for the parameters of mood, refreshment was significantly increased. Though fatigue remained unchanged, anxiety and depression decreased while the score for excitement tended to increase. Thus, it was indicated that music therapy in a hospice setting reduces the stress level of patients and thereby plays a positive role in improving patients' quality of life.Journal of music therapy 02/2009; 46(2):160-72. · 0.80 Impact Factor -
Article: Garlic as an anti-fatigue agent.
[show abstract] [hide abstract]
ABSTRACT: More than three thousand publications in the past have confirmed the efficacy of garlic for the prevention and treatment of a variety of diseases, acknowledging and validating its traditional uses. Garlic is also used for the treatment of fatigue, although the mechanism involved remain unclear. The anti-fatigue function of garlic may be closely related to its many favorable biological and pharmacological effects. In animal studies, garlic has been shown to promote exercise endurance. Differences in the methods of processing garlic result in differences in the intensity of its anti-fatigue effect, and the most favorable form of processing has been shown to be extraction of raw garlic followed by its natural aging for a long period in a water-ethanol mixture. In human studies, it has been confirmed that garlic produces symptomatic improvement in persons with physical fatigue, systemic fatigue due to cold, or lassitude of indefinite cause, suggesting that garlic can resolve fatigue through a variety of actions. Recently, primarily in Japan, attempts have been made to measure the intensity of fatigue objectively and quantitatively using biomarkers. Currently available data strongly suggest that garlic may be a promising anti-fatigue agent, and that further studies to elucidate its application are warranted.Molecular Nutrition & Food Research 12/2007; 51(11):1329-34. · 4.30 Impact Factor -
Article: Muscle IGF-I Ea, MGF, and myostatin mRNA expressions after compensatory overload in hypophysectomized rats.
[show abstract] [hide abstract]
ABSTRACT: To determine whether IGF-I Ea, MGF, and myostatin mRNAs are related to GH-independent overload-induced muscle growth, we examined the expressions of IGF-I Ea and MGF mRNAs in the plantaris muscle after compensatory overload in hypophysectomized rats. The muscles were divided into four groups: normal-control, normal-overloaded, hypophysectomized-control, and hypophysectomized-overloaded. The weights of the plantaris muscle in the normal-overloaded were significantly higher than those of the normal-control. The weights of the hypophysectomized-overloaded were also significantly higher than those of the hypophysectomized-control. IGF-I Ea and MGF mRNAs in normal-overloaded and hypophysectomized-overloaded 3 days after overload were significantly higher than those of normal-control and hypophysectomized-control, respectively. Myostatin mRNAs in normal-overloaded and hypophysectomized-overloaded 3 days after the overload were significantly lower than those of normal-control and hypophysectomized-control, respectively. Thus, it was shown that IGF-I Ea, MGF, and myostatin mRNAs were expressed in association with muscle enlargement after compensatory overload independently of pituitary state. These observations suggest that the expression of IGF-I Ea, MGF, and myostatin mRNAs due to compensatory overload would be associated in a growth-hormone-independent manner.Pflügers Archiv - European Journal of Physiology 12/2006; 453(2):203-10. · 4.46 Impact Factor -
Article: Aged garlic extract ameliorates physical fatigue.
[show abstract] [hide abstract]
ABSTRACT: Aged garlic extract (AGE) has recently received attention as a potent anti-fatigue agent. The principal aim of this study was to elucidate the mechanism responsible for the ameliorating effect of AGE on physical fatigue in rats caused by repeated endurance exercise on a mechanical treadmill apparatus. Rats were subjected to endurance exercise 5 times per week for 4 weeks. AGE at a dosage of 2.86 g/kg was administrated to rats 30 min before every exercise. Succinate dehydrogenase (SDH) activity in the gastrocnemius and soleus muscles and superoxide dismutase (SOD) activity, nitric oxide (NO) metabolites, and lactic acid concentration in plasma were evaluated as biomarkers of physical fatigue. SDH activity was increased 2-4-fold by repeated endurance exercise in comparison with unexercised (intact) rats, and AGE further up-regulated this activity by 40%. SOD activity was increased 5-fold, whereas AGE maintained it at a level equivalent to that in intact rats. Levels of NO metabolites were slightly decreased, whereas AGE enhanced them 2-fold. Lactic acid concentration was not changed in any of the groups. These results indicate that AGE may facilitate the turnover of aerobic glucose metabolism, attenuate oxidative stress, and promote oxygen supply based on vasodilation, suggesting that AGE ameliorates the various impairments associated with physical fatigue.Biological & Pharmaceutical Bulletin 06/2006; 29(5):962-6. · 1.66 Impact Factor -
Article: mRNA expression of fibroblast growth factors and hepatocyte growth factor in rat plantaris muscle following denervation and compensatory overload.
[show abstract] [hide abstract]
ABSTRACT: We addressed the question of whether hypertrophy induced by compensatory overload differs according to innervation status, and how fibroblast growth factors (FGF) and hepatocyte growth factor (HGF) mRNAs are expressed in the rat plantaris muscle during overload (OL) and/or denervation. Male Wistar rats were divided into four groups (Normal-Cont, Normal-OL, Denervated-Cont, and Denervated-OL). according to the plantaris denervation and/or overload. Three weeks later, plantaris weight in Denervated-Cont and Denervated-OL was significantly lower than in the Normal-Cont. The muscle weights in the Normal-OL were higher than in the Normal-Cont. The muscle weights in the Denervated-OL were higher than in the Denervated-Cont. Three days after the treatment, FGF-2, FGF-6, FGF-7 and HGF mRNAs in the Normal-OL were significantly higher than those in the Normal-Cont. FGF-2, FGF-6, FGF-7 and HGF mRNAs in the Denervated-OL were also significantly higher after 3 days than those in the Denervated-Cont. After 7 days, FGF-2, FGF-5, FGF-6, FGF-7 and HGF mRNAs were significantly higher in the Normal-OL than those in the Normal-Cont. At 21 days, FGF-1, FGF-6 and HGF mRNA levels were significantly increased. In the Denervated-OL, FGF-2, FGF-7 and HGF mRNAs at 7 days, and FGF-2 mRNA at 21 days were significantly higher than those in the Denervated-Cont. FGF-2 and FGF-6 mRNA levels decreased significantly following denervation; however, FGF-1, FGF-5, FGF-7 and HGF mRNA levels increased and maintained this increase for the 21-days treatment period. Muscle hypertrophy was thus induced by compensatory overload irrespective of innervation status, possibly in association with certain FGFs and HGF. The differential mRNA expression patterns of FGFs and HGF observed following compensatory overload and/or denervation suggest distinct roles for individual FGFs and HGF in muscle hypertrophy and/or atrophy.Pflügers Archiv - European Journal of Physiology 09/2004; 448(5):539-46. · 4.46 Impact Factor -
Article: Effect of Acanthopanax senticosus Harms on biogenic monoamine levels in the rat brain.
[show abstract] [hide abstract]
ABSTRACT: The extract of the stem bark of Acanthopanax senticosus Harms (ASH) is known to have healing and protective effects on stress-induced disturbance of mental status. We have analysed whether a single or chronic (2 week) administration of ASH can affect concentrations of noradrenaline (NA), dopamine (DA) and their metabolites in the normal rat brain. A single p.o. administration of ASH elevated the NA and DA levels in the whole brain of rats in a dose-dependent manner. A single or 2 week administration of ASH (500 mg/kg) showed a marked increase in the DA level only in the striatum. However, NA levels were increased by a single dose of ASH in a wide range of brain regions such as the cortex, hypothalamus, striatum, hippocampus, substantia nigra and pons. When administered for 2 weeks no increase in NA levels was seen in these brain regions, except for an increase in the frontal cortex and anterior hypothalamus. The present results suggest that ASH may act by regulating NA and DA levels in specific brain regions related to stress response and Parkinson's disease.Phytotherapy Research 09/2002; 16(5):474-8. · 2.09 Impact Factor
