Summary Despite numerous defenses, the brain is vulnerable to apoptosis, mitochondrial permeability transition and oxidative stress resulting from ischemia reperfusion. poly ADP-ribose ; polymerase activation provides Excitotoxic stimulation of superoxide and nitric oxide additional mechanisms for oxidative damage and new production leads to formation of highly reactive products, targets for post-ischemic therapeutic intervention. including peroxynitrite and hydroxyl radical, which are Because oxidative stress involves multiple post-ischemic capable of damaging lipids, proteins and DNA. Use of cascades leading to cell death, effective prevention transgenic mutants and selective pharmacological treatment of ischemic brain injury is likely to require antioxidants has greatly increased understanding of the intervention at multiple effect sites. complex interplay between substrate deprivation and ischemic outcome. Recent evidence that reactive Key words: brain, ischemia, oxidative stress, antioxidant. oxygen nitrogen species play a critical role in initiation of Introduction Oxidative stress has been defined as `a disturbance in the pro-oxidantantioxidant balance in favour of the former, leading to potential damage' Sies, 1991 ; . The brain consumes a large quantity of oxygen, making it particularly susceptible to oxidative stress. Natural formation of oxidants during mitochondrial electron transport, auto-oxidation of some neurotransmitters e.g. norepinephrine, dopamine ; and initiation of events during hypoxia or ischemia, can result in oxidant formation and subsequent tissue damage. Oxidative stress can be traced primarily to formation of superoxide and nitric oxide. Both molecules have important roles in health, serving as regulators of blood flow and neurotransmission. Perturbation in the production and or metabolism of either molecule can have pathologic consequences. Principal sources of superoxide include electron leak during mitochondrial electron transport, perturbed mitochondrial metabolism and inflammatory responses to injury Halliwell and Gutteridge, 1999 ; . The brain has potent defenses against superoxide including dietary free-radical scavengers ascorbate, -tocopherol ; , the endogenous tripeptide glutathione, and enzymatic antioxidants. Enzymatic antioxidants regulate superoxide concentration by dismutation of superoxide to hydrogen peroxide superoxide dismutase or SOD; Fridovich, 1995 ; , which is then converted to water peroxidases such as glutathione peroxidase and peroxiredoxin ; or dismuted to water and oxygen catalase ; . Although increased expression of these enzymes can occur in response to ischemia Fukui et al., 2002 ; , endogenous antioxidant capacity can be overwhelmed, leading to increased superoxide and hydrogen peroxide concentrations. Nitric oxide formation is both constitutive and inducible. Ischemia-induced nitric oxide overproduction is in part caused by glutamatergic-mediated increases in intracellular calcium concentration, resulting in a calmodulin-dependent upregulation of nitric oxide synthase NOS; Dawson et al., 1991; Garthwaite et al., 1988, 1989 ; . Nitric oxide can be consumed by reacting with hemoglobin Ignarro et al., 1987; Joshi et al., 2002 ; . Flavohemoglobin-based enzymes nitric oxide reductase, nitric oxide dioxygenase ; capable of specifically metabolizing nitric oxide have been identified in bacteria Hausladen et al., 1998 ; , and flavohemoglobin-like activity has been identified in mammalian cells Gardner et al., 2001 ; . Yet, an important non-enzymatic mechanism regulating nitric oxide concentration is its reaction with superoxide yielding peroxynitrite Beckman et al., 1990 ; . Under pathophysiological conditions, excessive nitric oxide production can elicit nitrosative damage Espey et al., 2000 ; via independent nitrosylation of protein heme sites e.g. cytochrome c; Schonhoff et al., 2003 ; or through its reaction products with oxygen or other nitrogen oxides. Superoxide can cause oxidative damage of iron sulfur clusters of aconitase Gardner and Fridovich, 1991 ; , an important enzyme in the, for example, axod oral. Gestational goitrogenesis remains debatable. Ultimately, it probably depends on the extent of the deficiency in preexisting intrathyroidal iodine stores. The goal is to restore and maintain an iodine balance; this goal can be reached in most women with 100 200 g iodine day given as a supplement during pregnancy, at least in Europe. In regions with a more severe iodine deficiency, iodized oil given intraperitoneally or by a single oral dose ; has been shown to protect pregnant women from hypothyroidism for more than a year without significant side effects 159, 178 180 ; . 4. Consequences of iodine deficiency for the offspring. The functional maturation of the fetal thyroid gland follows a well characterized pattern, with the thyroid acquiring the capacity to concentrate iodine and synthesize iodothyronines by 10 12 weeks, its secretory activity becoming effective by midgestation, and total T4 levels rising progressively until term 181, 182 ; . Even though maternal and fetal thyroid functions are autonomously regulated, they are not independent of one another. There is evidence of at least some transplacental passage of maternal thyroid hormones, probably important in the early stages of fetal development. Moreover, the fetal thyroid activity depends entirely upon the availability of iodine transferred from the maternal circulation 183187 ; . In conditions with only a moderate iodine deficiency, it was reported in 1992 that although the mothers exhibited relative hypothyroxinemia at delivery, this was not the case for the newborn who had total and free T4 concentrations significantly higher than their respective mothers, which would suggest that the fetus was protected from hypothyroxinemia 188 ; . To achieve protection, and because of the very low intrathyroidal iodine stores in the fetus, the fetal thyroidal machinery is chronically subjected to an intense stimulation 189 ; . In our observations with nonsupplemented mothers, neonatal thyroidal stimulation was reflected by significantly higher TSH and TG concentrations found in cord serum, compared with TSH and TG values in mothers at delivery. These initial studies clearly indicated that only a moderate reduction in the iodine supply was sufficient to constitute a stimulus for both the maternal and neonatal thyroid glands, with relative iodine deficiency representing the common regulatory link 188 ; . The apparent paradox between subnormal free T4 in the mothers at term and normal free T4 concentrations in the newborn can partially be explained by the fact that the fetal thyroid gland is hypersensitive to alterations induced by iodine restriction. In adults with intrathyroidal iodine stores in the order of 10 20 mg and daily needs of 100 200 g iodine, the turnover rate of used iodine is 12% day. In the newborn, in contrast, intrathyroidal iodine stores are very low, representing, at most, 300 g when the iodine supply is sufficient, 50 100 g in Brussels, and as little as 25 g severely iodine-deficient areas 190 ; . Therefore, with daily needs of approximately 50 g iodine, the fetal gland turns over close to 100% of its stores to ensure the required daily hormone production, rendering both fetal and neonatal thyroid economies exquisitely sensitive to fluctuations in the iodine supply from the mother.

ULTRAM: JOHNSON & JOHNSON NYSE: JNJ ; Ultram tramadol HCl ; is a centrally acting synthetic opioid analgesic. Indicated for the management of moderate to moderately severe chronic pain, Ultram was approved in March 1995. Analgesia in humans begins approximately within one hour after administration and reaches peak levels in approximately two to three hours. While the mode of action of Ultram is not completely understood, laboratory studies suggest that at least two complementary mechanisms appear applicable: binding of parent and M1 metabolite to opioid receptors and weak inhibition of reuptake of norepinephrine and serotonin. Although different from other opioid analgesics, such as codeine or morphine, Ultram administration may produce a constellation of symptoms apart from analgesia including dizziness, somnolence, nausea, constipation, sweating and pruritus ; similar to that of other opioids. Tramadol has been prescribed in more than 21 million patients in the United States and 55 million patients worldwide. Ultram sales reached $650 million in 2001.
