Topiramate attenuates motor deficits after hypoxiaischemia in a rodent model of PVL White matter injury in the premature human infant presents as clinical spastic diplegia in the growing child. Because topiramate at 30 mg kg attenuated the histological white matter injury in the immature rat, we evaluated whether these cellular changes might be correlated with improvement in observable motor deficits. Muscle strength and coordination were evaluated by the ability of the rats to climb a variably inclined plane. We found that a significant contralateral limb dysfunction exists in the rat at P21 after UCL hypoxia at P7, consistent with the results of others Tomimatsu et al., 2002 ; , as well as a significant decrease in motor deficit in rats treated with topiramate for 48 hr after hypoxia Fig. 3 ; . All normal P21 rats can scamper up a 30 incline score of 4 ; and climb up a 45 incline without sliding score of 3 ; . After UCL hypoxia at P7, animals tested at P21 performed significantly worse than controls mean score, 2.75 0.01 at 30 o and 1.88 0.12 at 45 o ; and had significantly improved scores with topiramate treatment mean score, 3.64 0.11 at 30 o and 2.68 0.12 at 45 o; p 0.001 for all comparisons; one-way ANOVA with post hoc pair-wise analysis ; . Topiramate treatment at P79 30 mg kg every 12 hr for 2 d; n 5 ; normal littermates did not alter behavior at P21. These data demonstrate that topiramate can improve functional outcome after hypoxiaischemia. NBQX and topiramate attenuate excitotoxicity, kainateevoked currents, and Ca 2 influx in pre-OLs in vitro Excitotoxicity induced by OGD or kainate in pre-OLs in vitro has been shown to be Ca -mediated and secondary to AMPA kainate receptor activation Fern and Moller, 2000; Yoshioka et al., 2000; Deng et al., 2003 ; . Thus, we evaluated the effects of NBQX and topiramate on kainate or OGD-induced excitotoxicity and Ca 2 influx in pre-OL cultures. Pre-OLs were incubated with NBQX or topiramate, or both, each at concentrations ranging from 0 to 100 M, and exposed to either kainate 300 M ; or OGD 2 hr ; , with cell survival assessed at 24 hr. Topiramate or NBQX each attenuated kainate-induced pre-OL death in a dosedependent manner, with EC50 values of 28.9 3.0 and 12.3 1.8 M, respectively Fig. 4 A ; . OGD-induced pre-OL death was significantly reduced by topiramate EC50 12.4 2.4 M; p 0.05 ; or NBQX EC50 9.26 1.6 M; p 0.05 ; Fig. 4 B ; . Moreover, the effects of topiramate and NBQX were additive when the two agents were applied together at the concentrations that were not saturated for each compound. Thus in these paradigms, topiramate appears to be acting in a manner similar to the AMPA kainate receptor antagonist NBQX; however, because topiramate is known to have multiple mechanisms of action, we next determined what other mechanisms might play a role in the protection. Using the OGD model on pre-OLs in vitro, we evaluated the individual and combined effects of compounds that mimic each of the additional known mechanisms for topiramate: GABAA receptor agonist activity, blockade of Na and voltagegated Ca 2 channels, and carbonic anhydrase inhibition White, 1997; Schneiderman, 1998; Shank et al., 2000; Skradski and White, 2000 ; . No protection was observed with nontoxic dose ranges of the Ca 2 channel blockers nimodipine 2.5100 M ; and nifedipine 10 100 M ; , for GABA 0.12 mM ; , for the Na channel blocker tetrodotoxin TTX; 0.1 0.5 mM ; , or for the carbonic anhydrase inhibitor acetazolamide 0.11 mM ; when each was applied alone. In addition, there was no protection with combined administration of TTX 200 M ; , nimodipine 10 M ; , GABA 200 M ; , and acetazolamide 200 M ; . Taken together, these data strongly support the. 40 IU PMSG was unaffected Table 1 ; . Apart from one rat group, which showed little stimulation treatment and nicotine. Diagnosis of vasospasm begins by ruling out other potential causes, such as hydrocephalus, cerebral edema, seizure activity, hyponatremia, hypoxia, and sepsis. Onset generally occurs between 4 and 14 days post SAH. Although the gold standard of testing is cerebral angiogram, large-vessel spasm may also be detected utilizing transcranial Doppler TCD ; . TCD is a noninvasive cerebral artery velocity evaluation. Utilization of hand-held Doppler technology through temporal bone windows enables monitoring of large cerebral vessels. Because major vessels are the only arteries assessible with this technology, TCD should be used as a screening tool and angiograms employed as the definitive form of evaluation. Once diagnosed, or if increased risk is suspected, several treatment options can be implemented to prevent or minimize sequelae from vasospasm. An initial prevention strategy is the use of nimoxipine Nimotop ; . This calcium channel blocker is the only pharmacologic agent found useful in vasospasm treatment Kassell et al., 1990 ; . The dose is 60 mg orally every four hours; if hypotension occurs, 30 mg every two hours may be given for 21 days. Hyperdynamic or triple-H therapy is another vasospasm treatment option. The use of hypertensive therapy as a treatment against vessel narrowing was first noted in 1951. Further evaluation of this concept was not achieved until the late 1960s, when the use of volume expanders and vasopressors to raise blood pressure were noted to reverse or minimize neurologic symptoms Molyneux et al., 2005 ; . More widespread use of triple-H therapy began with the "early treatment of aneurysm" trend. In the late 1970s, a small cohort of patients with symptomatic vasospasm was treated with colloids and phenylephrine Neosynephrine ; to induce hypertension, and their.

Discussion Concerning the results obtained in our in vivo study, chronic exposure to nimodipine is not associated with genotoxic effects because no significant increases in the frequency of SCE and MN were found in patients as compared with controls T-1. The results of the in vitro study were quite different. Ninodipine at a concentration similar to that achieved during in vivo therapy was incapable of inducing SCE in peripheral lymphocytes after exposure in vitro. However, nimodipine led to a statistically significant enhancement of the two variables studied in the MN assay, total number of MN and total number of BNMN. These data suggest that in vitro exposure to nimodipine results mainly in induction of chromosome loss. This suggestion was confirmed by FISH analysis using an -satellite probe for all human centromeres. The statistically significant differences in CN MN between controls T-1 and. Study selection and data extraction: basic pharmacology data were extracted from animal studies; pharmacokinetic data were extracted from human studies, for example, hematoma. N March 13, 2006, six participants in a London drug trial were sent to the hospital within hours of receiving the first dose of a trial medication. All had multiple organ failure and nearly died, and all may have permanent immune system damage. The most critically injured man was still hospitalized more than 10 weeks later, and gangrene has caused sloughing of some of his fingers and toes. A subsequent inquiry by the United Kingdom's Medicines and Healthcare Products Regulatory Authority MHRA ; concluded that these disastrous results from the monoclonal antibody TGN1412 were caused by "[a] previously unknown biological effect on humans that did not arise in any of the animal testing phases." TGN1412 is directed against a specific class of immune cell receptors, and animal studies convinced the German drug manufacturer TeGenero AG that TGN1412 was and noroxin.
