Summary: | To observe changes of [Ca2+]i concentration and CaM, CaMK II and p-CaMK II of Ca2+/CaMK II signaling pathways in skeletal muscle tissue of rats with spleen-qi deficiency and intervention of Sijunzi decoction and extract of Hedysarum polybotrys.
Rats were randomized into four groups: normal control group, spleen-qi deficient model group, extract from Hedysarum polybotrys group and Sijunzi decoction group, ten rats in each group. After the spleen-qi deficient models were built by comprehensive application of rhubarb, exhaustive and hungry methods, and treatment groups were treated with extract from Hedysarum polybotrys at 6 g/(kg . d) or Sijunzi decoction at 20 g/(kg . d) for 21 d. Then, general existence,gastrointestinal hormones GAS and MOT levels, and activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase of skeletal muscle were evaluated. Also, confocal laser technology was used to test cellular[Ca2+]i concentrations in skeletal muscle and Western blotting technique was used to test CaM, CaMK II and p-CaMK 11 exp |
