Interleukin-6 as a Director of Immunological Events and Tissue Regenerative Capacity in Hemodialyzed Diabetes Patients.

Hemodialyzed patients have innate immunity activation and adaptive immunity senescence. Diabetes mellitus is a frequent cause for chronic kidney disease and systemic inflammation. We studied the immunological pattern (innate and acquired immunity) and the tissular regeneration capacity in two groups of hemodialyzed patients: one comprised of diabetics and the other of non-diabetics.

Neurotrophin-3, TNF-alpha and IL-6 relations in serum and cerebrospinal fluid of ischemic stroke patients.

Pro-inflammatory cytokines and neurotrophins in the central nervous system (CNS) have been recognized as mediators of both neurodegenerative and neuroprotective mechanisms in a number of CNS pathologies. A rapid, sustained elevation of these molecules was recently reported after traumatic and ischemic brain injury. Inflammatory mechanisms and immune activation have been hypothesized to play a role in the pathogenesis of cerebral ischemia.

Ethanol-induced dysfunction of hepatocytes and leukocytes in patients without liver failure.

The repeated intake of a great amount of ethanol is followed by functional and organic changes in the body. The intestinal absorption of alcohol is accompanied by an increased absorption of Gram negative bacteria endotoxins in the portal blood. In the liver, endotoxins stimulate CD14 receptors on the membrane of Kupffer cells, with a secondary inflammatory liver response, consisting in the secretion of proinflammatory cytokines and acute phase proteins.

Oxidative aggression in atherosclerosis associated to degenerative psychoorganic disturbances.

We had in view the effect of the oxidative aggression as determinant factor in atherogenic process associated with degenerative psychoorganic disturbances. It was studied a group of old people distributed in two subgroups: a) 51 old people with atherosclerosis (AS) and b) 57 old people with atherosclerosis associated with degenerative psychoorganic disturbances determined by chronic ethylism. The results were compared to those of a 40 healthy adults group.
