in recent years, great efforts have been devoted to the design of drug delivery systems. many polymeric excipients have been studied in order to make drug release fit the desired profiles. the aim of this work was to design a theophylline oral suspension, as sustained release pharmaceutical preparation in order to decrease the plasma level fluctuations and adverse effects of theophylline. micro...

Abstract Coal dust is a primary threat to underground coal miners. The most common approach control hydraulic methods, such as water spray and seam injection. To improve the suppressant efficiency of novel chemical composite suppressant, called NCZ, was prepared in this study using calcium chloride (CaCl 2 ), magnesium (MgCl nonionic surfactants thermal synthesis method. water-retaining propert...

to investigate the influence of salinity and calcium (ca) on some properties of plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in jiroft, south of kermanprovince, iran. three salinity levels of 0, 100 and 200 mm nacl and ca levels of 0, 5 and 10 mm calcium nitrate wereapplied as the first and second factors, respectively. ...

one of the problems encountering gerbera production is the decreasing flower quality and yield especially when grown in non-standard greenhouse coditions. in this research the effect of weekly humic acid (ha) (500 mg/l) spray was studied and compared with application of 2 solutions containing 3.5 and 7 meq/l of calcium along with the same concentration of ha on gerbera jamesonii l. it was demon...

backgrounds and aims: stroke incidence rate has increased during the past 2 decades. the question of whether calcium, chloride, potassium, sodium levels are associated with stroke has remained controversial. the present study aimed to evaluate the serum levels of potassium, sodium, calcium, and chloride within stroke patients. materials and methods: the study participants consisted of 53 cconse...

today, the use of coatings is common to maintain the quality of fruits in storage period. previous studies have shown that the calcium compounds can improve and preserve the strength of fruit’s cell wall. in this research, the effect of calcium chloride dehydrate (cacl2*2h2o) concentration on two varieties of apple (golden delicious and red delicious), was studied. the apples were immersed in t...
