background: osteopenia is common problem in premature infants. low-birth weight babies do not receive adequate amounts of calcium and phosphorus through breast feeding. this study examines the effect of calcium and phosphorus supplements on osteopenia in premature infants. methods: this clinical trial included 42 premature infants hospitalized at razi hspital in kermanshah. all the babies had a...

Desensitization of adenylate cyclase-coupled beta-adrenergic receptors in avian erythrocytes results in a 40-65% decrease in agonist-stimulated adenylate cyclase activity and correlates with increased phosphorylation of beta-adrenergic receptors. To assess the role of phosphorylation in desensitization, membranes from isoprenaline- and dibutyryl cyclic AMP-desensitized turkey erythrocytes were ...

BACKGROUND This study was performed in an attempt to assess serum calcium, phosphorus, and alkaline phosphatase in adolescent girls and calcium supplementation in subjects with abnormal serum findings. METHODS A randomized, cross-sectional, cluster sampling, prospective, and descriptive trial was conducted from January through March 2003 for measurement of serum calcium, phosphorus, and alkal...

The hypothesis that the colonic epithelium is diffusely abnormal in ulcerative colitis was examined by comparing disease related responses in expression of markers of differentiation by colonic crypt cells to culture with and without butyrate. Cells were isolated from patients with normal colon (15), cancer (24), ulcerative colitis (19), or Crohn's disease (16). Alkaline phosphatase activities ...

Insulin affects the expression of brush border enzymes by villus cells in vitro and in vivo. Physiological (lactation) and surgical (jejunoileal bypass) models of hyper- and hypoplasia were established so that insulin receptor characteristics could be related to villus histology, expression of sucrase and alkaline phosphatase, and plasma insulin concentrations. In lactating rats, villus height ...

zeolites a, x and hs were synthesized from natural iranian kaolinite by alkaline fusion,,followed by refluxing the mixture. the transformation of zeolites x to hs and y to p were studied at different time intervals by x-ray diffraction and scanning electron microscopy (sem). it was revealed that in solution, zeolites hs and p are more stable than zeolites x and y respectively

The effect of nasal douching in 40 patients with chronic rhinosinusitis was tested, and two different preparations compared: 19 receiving traditional alkaline nasal douche and 21 receiving a sterile sea water spray, in addition to their regular treatment. Douching per se improved endoscopic appearances (p = .009), and quality of life scores (p = .008). These measures did not change in a control...
