soil ph is one of the important chemical characteristics of soil that plays major role in growing of tea plant and affects on absorbing of food elements by plant and their usability. in this study, the effect of different calcium source was investigated on some of quantifying parameters in tea plant, ph and ec in tea soil. tea is plant with shallow roots, this shrubs grows two forms wild and fa...

i ntroduction: calcium hydroxide (ch) is one of the most common intracanal medications. corticosteroids (cs) are used in endodontics because of their anti-inflammatory activity. this study aimed to evaluate the antimicrobial effect of ch+betamethasone and ch+saline against enterococcus faecalis ( e. faecalis ) using agar diffusion test and measuring the microbial zone of inhibition (zoi). metho...

introduction: the aim of this in vitro study was to evaluate the effect of calcium hydroxide (ch) on push-out bond strength of white mineral trioxide aggregate (wmta) and calcium-enriched mixture (cem) cement in simulated furcation perforations. methods and materials: furcation perforations, measuring 1.3 mm in diameter and 2 mm in height, were created in 80 human mandibular first molars. the t...

background calcium infusion is used as a pre-treatment before calcium channel blockers to prevent hypotension. occasional cardioversion with calcium gluconate infusion is seen in patients with paroxysmal supraventricular tachycardia. several mechanisms have been suggested for mechanism. herein we report a case presenting with atrial fibrillation but cardioverted with calcium gluconate infusion,...

summer pruning and calcium spray could improve kiwifruits quality. in this study, effect of summer pruning in two times, 2 and 15 days after petal fall alone or in combination with %1 calcium chloride spray on fruit quality and mineral elements contents of ‘hayward’ kiwifruit was investigated. calcium sprayed four times 90 days after petal fall with 15 days intervals. the results showed that su...

calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. in this study, various formulations of calcium acetate tablets were prepared and their disintegrati...

Hyperphosphatemia has an important role in the development of secondary hyperparathyroidism and bone disease in patients with end-stage renal disease (ESRD). The most effective method of phosphate elimination lies with phosphate binders, the agent that more commonly used, calcium carbonate, is not an ideal binding agent. In this regard, calcium acetate has been reported to have more or at least...
