convulsion is one of the most common problems in children and hypocalcemia is one the most frequent etiological items in children’s convulsion. corrected qt (qtc) in ekg is prolonged in hypocalcemia, so it can be a useful tool for evaluation of serum ionized calcium. in three groups (first seizure, multiple seizures, without seizure or control ) every 25 cases, qtc, serum ionized ca, total ca, ...

introduction : this investigation evaluates the effects of mineral trioxide aggregate (mta), calcium hydroxide (ch) and calcium enriched mixture (cem) as pulp capping materials on dental pulp tissues. materials and methods: the experimental procedures were performed on eighteen intact dog canine teeth. the pulps were exposed. cavities were randomly filled with cem, mta, or ch followed by glass ...

Background: This study investigated the effects of estradiol on plasma calcium and prolactin cells of Heteropneustes fossilis kept in calcium-deficient and normal freshwater. Methods: Fish were deprived of food and divided into groups A-D. Group A and B were kept in artificial freshwater with normal electrolytes. Group C and D were maintained in calcium-deficient freshwater. Vehicle was admin...

studies show that there is a substantial gap between the recommended daily calcium intake and what people actually consume. calcium food fortification is an effective method to increase daily calcium consumption. in the present study, the influence of three calcium salts at different levels was evaluated on physicochemical properties of set yoghourt such as ph, acidity, incubation time and syne...

background:   objective: in this study, we supplemented a chemically defined medium with different combinations of selenium, calcium and calcium ionophore concentrations to obtain the best rate of human oocytes maturation, survival, and fertilization.   materials and methods: as an experimental study, three combinations of [selenium (5 μg/ml), calcium (5 μg/ml) and calcium ionophore (1 μg/ml)],...

BACKGROUND Haemorrhoids are variceal dilatations of the anal and perianal venous plexus and often develop secondary to the persistently elevated venous pressure within the haemorrhoidal plexus (Kumar 2005). Phlebotonics are a heterogenous class of drugs consisting of plant extracts (i.e. flavonoids) and synthetic compounds (i.e. calcium dobesilate). Although their precise mechanism of action ha...
