OBJECTIVE To observe the effects of fenvalerate on calcium homeostasis in rat ovary. METHODS Female Sprague-Dawley rats were orally given fenvalerate at daily doses of 0.00, 1.91, 9.55, and 31.80 mg/kg for four weeks. The ovary ultrastucture was observed by electron microscopy. Serum free calcium concentration was measured by atomic absorption spectrophotometry. The activities of phosphorylas...

BACKGROUND Significant impairment in health-related quality of life (HRQOL) among dialysis patients could be partly explained by some co-morbid disorders, such as chronic kidney disease-mineral and bone disorder (CKD-MBD). Also disturbance in calcium and phosphorus metabolism would increase mortality and morbidity. Therefore, further efforts to treat these abnormalities may improve the survival...

BACKGROUND The purpose of the present study was to determine the effect of additional calcium carbonate treatment on fibroblast growth factor 23 (FGF23) levels in patients treated with calcitriol. METHODS In this randomized, open-labeled, and parallel-group study, a total of 30 patients with early chronic kidney disease (CKD) and vitamin D deficiency were randomly assigned to two groups and r...

In 1923, Salvesen and Linder (1) pointed out that hypoproteinemia in the nephrotic type of Bright's disease is associated with hypocalcemia, the calcium content of the serum tending to parallel the total serum protein level. Marrack and Thacker (2) and Hastings, Murray and Sendroy (3) subsequently expressed this proportionality between total calcium and total protein more precisely in the form ...

considering the fact that early hypocalcemia is the most common type of neonatal hypocalcemia which manifests during the first few days of iife (72 hours) and that hypocalcemia in low birth weight neonates is very common, this descriptive study on hypocalcemia was conducted to determine the frequency of hypocalcemia in low birth weight neonates in the city of kashan in the first 9 months of the...

Background: Iran is one of the major consumers of opium and opiate substances in the world. Addiction has become a very important issue in the 21st century and an urgent one in Iran. The consumption of this substance leaves a variety of impacts on the human body. The goal of this study is to investigate the changes of the biochemical parameters derived from opiate substances in addicts during t...

BACKGROUND The aim of this cross-sectional study was to examine the association between serum calcium and the components of metabolic syndrome (MetS). METHODS As a part of the national prevention program of diabetes in Finland (FIN-D2D), a randomly selected study population of 4500 middle-aged men and women were recruited from three central hospital district areas. Anthropometric measurements...
