Effect of 1,25-dihydroxy-vitamin D3 in experimental sepsis
BACKGROUND In addition to the regulation of calcium homeostasis, vitamin D affects the cellular immune system, targets the TNF-alpha pathway and increases vasoconstrictor response to angiotensin II. We therefore examined the effect of 1,25-dihydroxy-vitamin D(3) on coagulation and organ failure in experimental sepsis in the rat. METHODS Three series of placebo-controlled studies were conducte...
متن کاملIn vitro cellular muscle calcium metabolism. Characterization of effects of 1,25-dihydroxy-vitamin D3 and 25-hydroxy-vitamin D3.
Cultures of vitamin D-deficient chick soleus muscle and 12 day-old chick embryo myoblasts were used to characterize the effects of 1,25-dihydroxy-vitamin D3 and 25-hydroxy-vitamin D3 on muscle cell Ca metabolism. Physiological amounts of both sterols increased the rate and extent of 45Ca uptake by cultures. However, 1,25(OH)2D3 was significantly more effective than 25 OHD3. The greater potency ...
متن کاملAndrographolide disrupts meiotic maturation by blocking cytoskeletal reorganisation and decreases the fertilisation potential of mouse oocytes.
Andrographolide (AG) is a diterpenoid lactone isolated from the stem and leaves of Andrographis paniculata Nees that is used for the effective treatment of infectious diseases in Asian countries. Previous studies have reported adverse effects of AG on female fertility in rodents; however, the underlying mechanisms are unknown. The aim of the present study was to investigate the effects of AG on...
متن کاملIsolation and chemical characterization of two new vitamin D metabolites produced by the intestine. 1,25-Dihydroxy-23-oxo-vitamin D3 and 1,25,26-trihydroxy-23-oxo-vitamin D3.
Two new vitamin D metabolites were isolated in pure form from incubations of 53 nM 1,25-dihydroxyvitamin D3 with homogenates of small intestinal mucosa of vitamin D-replete chicks. The birds were injected intravenously with 8 to 9 nmol of 1,25-dihydroxyvitamin D3/100 g body weight 5 to 8 h before death. The isolation involved methanol-chloroform extraction and four successive chromatographic pr...
متن کاملConvergence of vitamin D and lysophosphatidic acid signaling in stimulating human osteoblast maturation
Vitamin D is absolutely essential for the provision of a mechanically robust, mineralized bone collagen matrix. Whilst their continues to be a debate over the precise role of this steroid in bone biology it is unequivocal that active vitamin D3 metabolites have direct effects on the control of human osteoblast (hOB) function, matrix calcification and overall bone metabolism. Indeed van de Peppe...
