②Effect of exercise on the androgen of regulated calcium: Calcium and phosphate metabolism and bone reconstruction are regulated by parathytin, 1α, 25(OH)2D3 and calcitionin.
The calcium,calcium and manganese could increased the activity of SOD,POD and CAT,decreased the O_2~- production rate and accumulation of H2O2. At the same time ,manganese treatment also increased the activity of SOD and POD,so it could reduced the injury of O_2~-.
and H2O2 on the peach fruit,but it restrain the activity of CAT ,and accumulated the content of H_2O_2.The calcium, calcium and manganese treatments bated the activity of PPO and decreased hydroxybenzend content,reduced the incidence of fruit decay and brown.
⑤Simvastatin group(n=9). The measurement of plasma levels of cholesterol, triglyceride and calcium, calcium content in artery and bone, and pathologic observations of arteries were made.
The paper summarizes recent data about the mechanisms that determine the kinetics and amplitude of transient elevations in the intracellular level of free calcium ("calcium signals") in excitable cells.
In isolated rat pancreatic acinar cells, cholecystokinin octapeptide (cck-8) and carbachol increased free cytosolic calcium calcium concentration [Ca~(2+)]i)(as measured by the fluorescent probe fura 2). The maximal [Ca~(2+)] i values were 360±32 nmol/L for 1 nmol/L cck-8 stimulation and 380±20nmol/L for 1 mmol/L carbachol. Basal [Ca~(2+)]i level was 122±8 nmol/L. The action of cck-8 and carbachol were in a concentration-dependent manner with apparent half maximal concentration of 0.45 nmol/L an...
Two experiments were conducted in order to observe the effects of dietary calcium and zinc on the metallothioneine (MT) contents in liver and kindeys in layers. In the 1st experiment, 150 30-day-old healthy Rose chickens were randomly allotted to 3 groups (Ⅰ-1, Ⅰ-2, Ⅰ-3). All these chickens were fed with the basal feed containing 30 ppm of zinc in the form of zinc sulfate and supplemented with 0.72%, 3.0% and 6.0% calcium (calcium carbonate) for groups Ⅰ-1, Ⅰ-2, and Ⅰ-3 respectively. 220 d...
Reaction characteristics of artificial marmatite at high temperature were tested. Results show that marmatite has good thermal stability only in the presence of carbon reductant, and is easily decomposed by calcium oxide. The reduction between marmatite and calcium calcium goes even more rapidly in strong reducing at mosphere crcated by carbon reductant. Parameters and mechanism of marmatite decomposition and made out.
