In the present study we analyze the events which occur during the early stages of astrogliogenesis by examining the pattern of both GFAP and vimentin gene expression and their corresponding immunoreactive proteins during rat brain development. This study was carried out "in vivo" (whole brain) and "in vitro" (primary culture of radial glia) using(More)
Endocytosis constitutes an essential process in the regulation of the expression of cell surface molecules and receptors and, therefore, could participate in the neural-glial interactions occurring during brain development. However, the relationship between endocytic pathways in astroglial cells under physiological and pathological conditions remains poorly(More)
The aim of this study was to test the effect of lipoic acid treatment on the retina after a short diabetic insult. Diabetes was induced by alloxan and mice were divided into sub-groups; control, diabetic, diabetic+insulin and all groups received+/-lipoic acid (100 mg/kg body weight) for 3 weeks. GSH content, MDA concentration, GPx activity were measured and(More)
Ovarian cells that transcribe and translate the gene for tumor necrosis factor alpha (TNF alpha) were identified in the adult cyclic mouse by using in situ hybridization and immunocytochemistry. TNF alpha mRNA was observed in > 97% and protein was contained in approximately 53% of the oocytes of healthy follicles with two or more layers of granulosa cells,(More)
We demonstrate the presence of cytochrome P4502E1 (CYP2E1) in astrocytes in primary culture, its induction by ethanol, and the concomitant generation of free radical species. Double immunofluorescence using anti-CYP2E1 and anti-glial fibrillary acidic protein showed that CYP2E1 was distributed over the cytoplasm and processes, although labeling was more(More)
The effects of feeding an ethanol liquid diet for short (4-6 weeks) and long (48-50 weeks) periods on the extent of metabolic tolerance to the drug were studied in female rats. Appropriate pair-fed and solid-diet controls were also included. At the end of both periods of treatment, the rats (4 or 14-month-old), received an acute dose of ethanol (2 g/kg body(More)
Using astrocytes obtained from 21-day-old rat fetuses, in primary culture, we have analyzed the effect of prenatal alcohol consumption on DNA and protein synthesis of astrocytes during their development. The variation in sensitivity of astrocytes to ethanol “in vitro” during the proliferation and maturation periods was also assessed. Control astrocytes(More)
The pathophysiology of the early events leading to diabetic retinopathy is not fully understood. It has been suggested that Inflammatory processes are involved in the development of the disease; however, the concentrations of tissue retinal inflammatory mediators and their possible alteration in diabetic retinopathy have not been described. The aim of this(More)
The effect of chronic ethanol intake during gestation was studied in rats fed a liquid diet in which ethanol provided 36% of the total calories. The animals were chronically alcoholised before mating, and the body weight gain and nutritional status during pregnancy were noted. Blood ethanol levels were measured during pregnancy and parturition.(More)
Inflammation results in the production of free radicals. We evaluated the anti-inflammatory and antioxidant capacity of lipoic acid in an experimental uveitis model upon a subcutaneous injection of endotoxin into Lewis rats. The role of oxidative stress in the endotoxin-induced uveitis model is well-known. Besides, the Th1 response classically performs a(More)
