Hepatic energy metabolism on rats by six traditional Chinese medicine with hot property / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the common rule of hepatic energy metabolism on rats by six traditional Chinese medicine (TCM) with hot property.</p><p><b>METHOD</b>The activity of Na(+)-K(+)-ATPase, Ca2(+)-ATPase and succinate hydrogenase (SDH), the content of hepatic glycogen and the mRNA expression of hepatic uncoupling protein2 (UCP2) were measured after the rats were administrated with water extracts of Radix Aconiti Lateralis Preparata, Rhizoma Zingiberis, Rhizoma Alpiniae Officinarum, Pericarpium Zanthoxyli and Cortex Cinnamomi, Fructus Evodiae at the dose of 10.5, 8.4, 6.0, 4.0, 3.5, 4.2 g x kg(-1). respectively in 30 days, twice a day.</p><p><b>RESULT</b>The activity of Na+(-)K(+)-ATPase has been increased by the six TCM and the statistical significance has been observed in Rhizoma Alpiniae Officinarum, Pericarpium Zanthoxyli, Fructus Evodiae groups. The raising tendency of Ca2(+)-ATPase activity has been observed by the six TCM and the statistical significance has been obtained in Rhizoma Alpiniae Officinarum group. The activity of SDH has been increaseded by six TCM while statistical significance has been observed except in five groups of the six groups except in Radix Aconiti Lateralis Preparata group. The content of hepatic glycogen has been decreased significantly by six TCM. No signiticant change of the mRNA expression of UCP2 has been found.</p><p><b>CONCLUSION</b>TCM has good effects on hepatic energy metabolism by raising the activity of mitochondria SDH to increase the production of ATP and by increasing the activity of Na(+)-K+)-ATPase, Ca2(+)-ATPase to increase the consumption of ATP.</p>

Effect on factors of energy metabolism in rats skeletal muscle by cold traditional Chinese medicine / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the effect of six cold traditional Chinese medicine on the energy metabolism factors in rats skeletal muscle.</p><p><b>METHOD</b>The activity of Na(+)-K(+) -ATPase, Ca(2+) -ATPase and succinate dehydrogenase (SDH), the content of muscle glycogen, and the mRNA expression of skeletal muscle uncoupling protein 3 (UCP3) were measured after rats having been administrated with water extracts of Radix Sophorae Flavescentis, Fructus Gardeniae, Cortex Phellodendri, Radix Scutellariae, Rhizoma Coptidis, and Radix Gentianae respectively at the dose of 6.0, 7.0, 8.4, 6.0, 7.0, 4.0 g x kg(-1) for 30 days.</p><p><b>RESULT</b>The activity of Na(+) -K(+) -ATPase has been depressed significantly and the content of skeletal muscle glycogen has been increased remarkably by six cold traditional Chinese medicine. The decreased tendency has been found on activity of Ca(2+) -ATPase and SDH, only the Radix scutellariaeg group decreased the Ca(2+) -ATPase activity significantly (P < 0.05), the SDH activity was decreased high significantly by Radix scutellariae, Cortex Phellodendri, Radix Gentianae and significantly by Rhizoma Coptidis. The mRNA expression of UCP3 has been decreased high significantly by all five cold traditional Chinese medicine except Cortex Phellodendri group with the decreased tendency of UCP3 mRNA expression.</p><p><b>CONCLUSION</b>The cold traditional Chinese medicine has the significant effects on the skeletal muscle energy metabolism by decreasing the utlization of the glucose and the activity of mitochondria SDH to reduce the production of ATP, and depressing the activity of Na(+)-K(+) -ATPase and Ca(2+) -ATPase to cut down the consumption of ATP, by decreasing the mRNA expression of UCP3 to decrease the heat production.</p>

Study of hepatic energy metabolism on rats by six cold property traditional Chinese medicines / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the common rule hepatic energy metabolism on rats by six cold property of traditional Chinese medicines (TCM).</p><p><b>METHOD</b>The activities of Na+ - K+ - ATPase, Ca2+ - ATPase and SDH, the content of hepatic glycogen, and the mRNA expression of hepatic uncoupling protein 2 (UCP2) were measured after the rats and been administrated with water extracts of Radix Sophorae Flavescentis, Fructus Gardeniae, Cortex Phellodendri, Radix Scutellariae, Rhizoma Coptidis, Radix Gentianae respectively at 6.0, 7.0, 8.4, 6.0, 7.0, 4.0 g x kg(-1) doses for 30 days, twice a day.</p><p><b>RESULT</b>The activities of Na+ - K+ - ATPase, Ca2+ - ATPase and SDH were depressed significantly by six cold property TCM. The decreased tendency of SDH was observed by six cold property of TCM, while statistical significance was obtained in Cortex Phellodendri, Radix Scutellariae, Rhizoma Coptidis, Radix Gentianae. The increased tendency of hepatic glycogen content was found by six cold property TCM, while statistical significance was not obtained in six groups. The decreased tendency of the mRNA expression of UCP2 was found by six cold property TCM, while statistical significance was obtained in Radix Sophorae Flavescentis, Cortex Phellodendri, and Radix Scutellariae groups.</p><p><b>CONCLUSION</b>The six cold property TCM have the good effects on hepatic energy metabolism by decreasing the activity of mitochondria SDH to reduce the production of ATP by decreasing the activities of Na+ - K+ - ATPase, Ca2+ - ATPase to cut down the consumption of ATP, by decreasing the mRNA expression of hepatic UCP2 to decrease the heat production.</p>
