background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...
We studied the effects of lidocaine and tetrodotoxin (TTX) on hypoxic changes in CA1 pyramidal neurons to examine the ionic basis of neuronal damage. Lidocaine (10 and 100 microM) and TTX (6 and 63 nM) delayed and attenuated the hypoxic depolarization and improved recovery of the resting and action potentials after 10 min of hypoxia. Lidocaine (10 and 100 microM) and TTX (63 nM) reduced the num...
Studies were undertaken in man to evaluate the roles of volume depletion and of the parathyroid glands in mediating the changes in serum and urinary calcium which follow the administration of hydrochlorothiazide, 100 mg twice daily, for 4 days, 42 studies were carried out in 16 normal subjects, 9 patients with hyperparathyroidism, and 7 vitamin D-treated subjects with hypoparathyroidism. In six...
in this investigation, the effects of the precooking (cooking with saturated steam, microwave and oven) and sterilization (115, 120 and 130 ° c, with same sterilization value) on the amount of iron, zinc, copper, calcium, sodium, of silver carp was studied during canning process. the results of measuring elements in the raw and precooked fish were ranged from 3.05 to 4.19 for copper, 71.45 to 8...
normal 0 false false false en-us x-none ar-sa background: experimental studies provide evidence of a relationship between stroke and mineral intake but this information in human are still limited and inconsistent. the purpose of this study was to investigate sodium, calcium and iron intake and stroke in iranian patient and control population. materials and methods: in a case-control study with ...
Background: Calcium-antagonists (CA) are heterogeneous group of drugs with different efficacy in migraine prophylaxis. Several studies have firmly demonstrated flunarizine (FLU), and verapamil as the proven calcium-antagonists for migraine prophylaxis. Cinnarizine (CIN), is another CA with less complications and less antihistaminic action. There is very few studies to show the effect of this dr...
Earlier work with rat arteries has resulted in a widely held assumption that resistance artery smooth muscle will not contract on exposure to a reduced transplasmalemmal sodium gradient. In view of the well-recognized low sensitivity of rat tissue to cardiac glycosides, we have investigated the effects of altering the transplasmalemmal sodium gradient on vascular smooth muscle tone by using hum...
یک سری پنج تایی لیگاند چهار دندانه سولفور دهنده: en-bis-dtcna = ethylenebisdithiocarbamate sodium salt pn-bis-dtcna = propylenebisdithiocarbamate sodium salt bu-bis-dtcna = butylenebisdithiocarbamate sodium salt he-bis-dtcna = hexylenebisdithiocarbamate sodium salt oc-bis-dtcna = octylenebisdithiocarbamate sodium salt تهیه شده است. این لیگاندها به روش های ir ,1h-nmr و تجزیه عنصری شن...
Voltage clamp studies with the squid giant axon have shown that changes in the external calcium concentration (Frankenhaeuser and Hodgkin, 1957) shift the sodium and potassium conductance versus membrane potential curves along the potential axis. Taylor (1959) found that procaine acts primarily by reducing the sodium and, to a lesser extent, the potassium conductances. Both procaine and increas...
Mesoporous phosphosilicate nanoparticles of hollow sphere architecture have been prepared hydrothermally for the first time under acidic pH conditions and this material is found to be efficient in encapsulating an antibiotic drug and its controlled release at physiological pH for possible cargo delivery applications.
