In vitro secretion of human chorionic gonadotrophin by bladder tumour cells

Effect of bromodichloromethane on chorionic gonadotrophin secretion by human placental trophoblast cultures.

Bromodichloromethane (BDCM) is a trihalomethane found in drinking water as a by-product of disinfection processes. BDCM is hepatotoxic and nephrotoxic in rodents and has been reported to cause strain-specific full-litter resorption in F344 rats during the luteinizing hormone-dependent phase of pregnancy. In humans, epidemiological studies suggest an association between exposure to BDCM in drink...

Sildenafil Effect on Nitric Oxide Secretion by Normal Human Endometrial Epithelial Cells Cultured In vitro

Analysis of chorionic gonadotrophin secreted by cultured human blastocysts.

Embryos produced in an in-vitro fertilization (IVF) programme, but which were unsuitable for transfer to patients because they originated from one (1PN) or three pronuclear (3PN) oocytes or because they originated from two pronuclear (2PN) oocytes but cleaved normally, were maintained in tissue culture. The embryos that progressed to blastocytes were cultured to day 14 of development in order t...

Secretion of vascular endothelial growth factor/vascular permeability factor from human luteinized granulosa cells is human chorionic gonadotrophin dependent.

Vascularization is a prominent event during corpus luteum formation, providing low density lipoproteins for steroid biosynthesis and enabling transport of secreted steroids. The process of vascularization is controlled by specific regulators. Vascular endothelial growth factor (VEGF), otherwise named vascular permeability factor (VPF), induces endothelial cell proliferation as well as angiogene...

Modulation of in vitro proliferation and cytokine secretion of human lymphocytes by Mentha longifolia extracts

Objective: Mentha longifolia L. Hudson has been used in folk medicine for various purposes especially for its anti-inflammatory effects. Lymphocytes play a central role in development of inflammation. In the present study, we investigated the immunomodulatory effects of different extracts of M. longifolia on human peripheral blood lymphocytes (PBLs), as main players in development of inflammati...
