alpha tocopherol/fever

Maternal hyperthermia induces pre-implantation embryo death, which is accompanied by enhanced physiological oxidative stress. We evaluated whether the administration of DL-alpha-tocopherol acetate (TA) to hyperthermic mothers mitigated pre-implantation embryo death. Mice were exposed to heat stress

Retinol (vitamin A), alpha-tocopherol (vitamin E), and Zn are micronutrients essential for health and performance. We determined the effects of parturition, lactation, and periparturient Ca status on plasma retinol, alpha-tocopherol, and Zn in 18 Jersey cows during the 2 wk before and after

As immune cells are often subjected to hyperthermia that can easily occur either after intense and/or prolonged exercise or during defense against pathogens, in this paper we analysed whether superoxide anion production occurred in lymphocytes exposed to high temperature and, consequently, if

The effects of high hemoglobin-oxygen affinity (HOA) on rectal temperature and lipid free radical oxidation were investigated in red blood cells, heart, liver and kidneys of male rats during fever. Fever was induced by intraperitoneal injection of Salmonella typhi lipopolysaccharide (LPS; 5.0 mg

Endogenous hyperthermia was induced in rabbits by i.v. pyrogenal administration. Hemoglobin-oxygen affinity and parameters of free radical lipid oxidation in plasma and red blood cells were measured. The content of diene conjugates, malonic dialdehyde and Schiff bases were determined at a pyrogenal

BACKGROUND Familial Mediterranean fever (FMF) is a genetically linked disorder common amongst races of the Eastern Mediterranean region. Typical symptoms include episodic pain syndrome extending throughout the chest or abdomen associated with histopathological signs of amyloidosis of the

OBJECTIVE The purpose of this study was to investigate the role of oxidant stress in the clinical process and pathogenesis of acute rheumatic fever (ARF). METHODS The study included 33 children with ARF and 20 healthy control subjects. The diagnosis of ARF was established according to the Jones

BACKGROUND Nitric oxide (NO) is one of the most important biologic messengers and takes part in the development of fever. It can influence on the body prooxidant-antioxidant balance by different ways including interaction with hemoglobin (Hb). METHODS The effects of nitric oxide synthesis inhibition

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin are widely used in the treatment of inflammation, fever and pain. However, NSAIDs cause gastric damage as a major adverse reaction. In this study, the effects of vegetable oils (corn, olive and sunflower oils) and alpha-tocopherol on

Several non-surgical tumor treatment modalities produce their cytotoxic activity by generating reactive oxygen species (ROS). Anti-oxidative enzymes such as superoxide dismutase (SOD) or exogenously supplied antioxidants may therefore reduce the efficacy of these treatments. The aim of the present

Many tumor treatment modalities such as ionizing radiation or some chemotherapy induce reactive oxygen species (ROS) resulting in therapeutic cell damage. The aim of this study was to analyze whether such ROS induction may affect the mechanical stability of solid tumor tissue by degradation of the

The role of active oxygen species and lipid peroxidation in the antitumor effect of hyperthermia was studied in an experimental rabbit model. VX2 tumors were transplanted into rabbit hind legs, and the effect of hyperthermia on tumor growth was measured at 7 and 14 days after heating. As an index of

OBJECTIVE We studied alterations of circulating antioxidant nutrients in patients with classic dengue fever in the tropical lowlands of Guatemala. METHODS In nine patients with dengue fever and 12 healthy Guatemalan control subjects, we assessed plasma concentrations of retinol, alpha-tocopherol,

Methamphetamine (MA)-induced dopaminergic neurotoxicity is believed to be associated with the increased formation of free radicals. This study examined the effect of alpha-tocopherol (alpha-TC), a scavenger of reactive oxygen species, and deferoxamine (DFO), an iron chelator, on the MA-induced
