In pregnancy, the decidual cells produce and secrete large amounts of macrophage colony-stimulating factor (M-CSF). M-CSF stimulates the proliferation and differentiation of trophoblasts. In addition, it stimulates them in a dose-dependent manner to produce certain hormones, such as human chorionic gonadotropin and human placental lactogen. Based on these facts, M-CSF is considered to be an essential cytokine for placental maintenance. Because placental dysfunction may sometimes result from preeclampsia, ascertaining blood M-CSF levels in preeclamptic patients would be of interest. The blood was collected from 33 subjects, of whom 19 were normal pregnant women and 14 were preeclamptic patients. The M-CSF level was determined by the sandwich enzyme-linked immunosorbent assay method using three antibodies. The investigators measured peripheral blood M-CSF levels in preeclamptic subjects and compared them with levels in subjects with normal pregnancies. This study showed that peripheral blood M-CSF levels were significantly higher in preeclamptic patients in the 30th and 38th weeks of pregnancy (P < .005). This is the first report concerning high M-CSF blood levels in preeclamptic patients.
Cisplatin affected the levels of NAG, beta 2MG, uCr and TP without influencing BUN and sCr levels. Fosfomycin, therefore, may be useful as a supplemental treatment for reducing cisplatin nephrotoxicity, especially proximal tubular damage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
