Abstract
BACKGROUND AND PURPOSE Delayed cerebral ischemia (DCI) is a complication of aneurysmal subarachnoid hemorrhage (SAH). Arterial cerebral vasospasm (CVS) is discussed as the main pathomechanism for DCI. Due to positive effects of per os nimodipine, intraarterial nimodipine application is used in patients with DCI. Further, percutaneous transluminal balloon angioplasty (PTA) is applied in focal high-grade spasm of intracranial arteries. However, clinical benefits of those techniques are unconfirmed in randomized trials so far, and complications might occur. We analyzed the occurrence of new infarcts in patients with severe CVS treated intra-arterially to assess benefits and risks of those techniques in a large single-center collective. MATERIALS AND METHODS All imaging and clinical data of 88 patients with CVS after SAH and 188 procedures of intraarterial nimodipine infusion and additional PTA in selected cases (18 patients, 20 PTA procedures) treated at our institution were reviewed. In the event of new infarcts after endovascular treatment of CVS, infarct patterns were analyzed to determine the most probable etiology. RESULTS Fifty-three percent of patients developed new cerebral infarction after intraarterial nimodipine and additional PTA in selected cases. Hereunder 47% were caused by persisting CVS. In 6% of patients, 3% of procedures respectively, new infarcts occurred due to complications of the intraarterial treatment including thromboembolism and arterial dissection. Of those, 3% of patients, 2% of procedures respectively, were assigned to thrombembolic complications of digital substraction angiography for intraarterial nimodipine. 17% of all patients treated with PTA (3/18=17%) showed infarction as a complication of PTA (15% of all PTA procedures). In 1% of patients, etiology of new infarction remained unclear. CONCLUSION Ischemic complications occur in about 6% of patients treated intraarterially for CVS, 3% of procedures respectively. Further, to date a benefit for patients treated with this therapy could not be proven. Therefore, intraarterial treatment of CVS should be performed only in carefully selected cases.

Abstract
The pharmaceutical effects of non-steroidal anti-inflammatory drugs (NSAIDs) occur through the inhibition of prostaglandin H synthase (PGHS). Prostaglandin H2 is produced from arachidonic acid via peroxidase and cyclooxygenase cycles in PGHS. NSAIDs exhibit different levels of reactivity in these reaction cycles. To prevent the development of side effect while maintaining the beneficial effects of drugs, a therapeutic strategy should be used. A new classification of NSAIDs has been proposed based on reactivity to peroxidase. Class 1 includes the majority of NSAIDs, which react with horseradish peroxidase (HRP) compounds I and II. Also, their drugs exhibit spectral changes induced by PGHS peroxidase and diminished ESR signals of the tyrosyl radical of metmyoglobin. They reduce compounds I and II of HRP and scavenge tyrosyl radicals. The branched chain mechanism by which the porphyrin radical is transferred to the tyrosine residue of the protein might be blocked by these NSAIDs. Class 2 includes salicylic acid derivatives that react only with the porphyrin radical and do not react with HRP compound II (oxoferryl species). Class 3 includes aspirin, nimesulide, tolmetin, and arylpropionic acid derivatives, including ibuprofen and the coxibs such as celecoxib and rofecoxib, which are not substrates for HRP or PGHS peroxidase. It seems that the selectivity of NSAIDs to PGHS1 and PGHS2 depends on their reactivity with cyclooxygenase rather than with the peroxidase of PGHS. The best drug for each inflammatory disease should therefore be selected for therapy.

Abstract
Background To functionally characterize pro-inflammatory and vasoconstrictive properties of cerebrospinal fluid after aneurysmal subarachnoid hemorrhage (SAH) in vivo and in vitro. Methods The cerebrospinal fluid (CSF) of 10 patients suffering from SAH was applied to the transparent skinfold chamber model in male NMRI mice which allows for in vivo analysis of the microcirculatory response to a superfusat. Microvascular diameter changes were quantified and the numbers of rolling and sticking leukocytes were documented using intravital multifluorescence imaging techniques. Furthermore, the pro-inflammatory properties of CSF were assessed in vitro using a monocyte transendothelial migration assay. Results CSF superfusion started to induce significant vasoconstriction on days 4 and 6 after SAH. In parallel, CSF superfusion induced a microvascular leukocyte recruitment, with a significant number of leukocytes rolling (day 6) and sticking (days 2-4) to the endothelium. CSF of patients presenting with cerebral edema induced breakdown of blood vessel integrity in our assay as evidenced by fluorescent marker extravasation. In accordance with leukocyte activation in vivo, significantly higher in vitro monocyte migration rates were found after SAH. Conclusion We functionally characterized inflammatory and vasoactive properties of patients' CSF after SAH in vivo and in vitro. This pro-inflammatory milieu in the subarachnoid space might play a pivotal role in the pathophysiology of early and delayed brain injury as well as vasospasm development following SAH.

Abstract
BACKGROUND AND PURPOSE Hypertensive basal ganglia hemorrhage (HBGH) accounts for 35%-44% of cases of hypertensive intracranial hemorrhage (ICH), which is one of the most devastating forms of cerebrovascular disease. In this study, intracerebral hematoma was evacuated with a burr hole craniectomy. The relationships of residue hematoma volume to brain edema, inflammation factors and the long-term prognosis of HBGH patients were studied. METHODS One hundred and seventy-six patients with HBGH were randomly divided into gross-total removal of hematoma (GTRH) and sub-total removal of hematoma (STRH) groups. The pre-operative and post-operative data of the patients in the two groups were compared. The pre-operative data included age, sex, hematoma volume, time from the ictus to the operation, Glasgow Coma Scale (GCS) scores, and the European Stroke Scale (ESS) scores. The post-operative information included edema grade, level of thromboxane B2 (TXB2), 6-keto-prostaglandin F1a (6-K-PGF1a), tumor necrosis factor-a (TNF-a) and endothelin (ET) in hematoma drainage or cerebral spinal fluid (CSF), ESS and Barthel Index (BI). RESULTS There was no statistical difference between the two groups (P>0.05) in the pre-operative data. The levels of TXB2, 6-K-PGF1a, TNF-a and ET in the GTRH group were significantly lower than those in the STRH group at different post-operative times. The ESS in the GTRH group increased rapidly after the operation and was higher than that in the STRH group. There was a significant difference between the two groups (P<0.05). The post-operative CT scan at different times showed that the brain edema grades were better in the GTRH group than in the STRH group. The BI was higher in the GTRH group than in the STRH group (P<0.05). CONCLUSIONS GTRH is an effective method to decrease ICH-induced injury to brain tissue. Such effect is related to decreased perihematomal edema formation and secondary injury by coagulation end products activated inflammatory cascade.

Abstract
INTRODUCTION Delayed cerebral vasospasm occurring after subarachnoid hemorrhage (SAH) is still responsible for a considerable percentage of the morbidity and mortality in patients with aneurysms. It has been suggested that the pathogenesis of delayed cerebral vasospasm is related to a number of pathological processes, including endothelial damage and smooth muscle cell contraction resulting from spasmogenic substances generated during lysis of subarachnoid blood clots, changes in vascular responsiveness, and inflammatory or immunological reactions of the vascular wall. It has been recognized that the endothelium plays an important role in the regulation of the cerebral vascular tone. In 1988, endothelin (ET)-1, a potent vasoconstrictor, was isolated from cultured porcine aortic endothelial cells. RESULTS ET-1, which is one of three distinct isoforms of ETs (ET-1, ET-2, and ET-3), has a more marked effect on cerebral arteries than do the other two isoforms. Elevated levels of ETs have been demonstrated in the cerebrospinal fluid and plasma of patients after SAH and cerebral infarction. ETs act by at least three different receptor subtypes, the ET(A) receptor, which is localized in vascular smooth muscle cells and mediates vasoconstriction, and two different ET(B) receptor subtypes. The ET(B1) receptor subtype is present in vascular endothelial cells and mediates the endothelium-dependent vasodilation. The ET(B2) receptor subtype is present in smooth muscle cells causing vasoconstriction. ET-1 acts from the adventitial but not from the luminal side of cerebral arteries. In vivo and in vitro ET-1 causes a dose-dependent and long-lasting vasoconstriction, similar to cerebral vasospasm after SAH. The vasoconstriction caused by ET-1 can be reversed by selective ET(A) receptor antagonists or combined ET(A) and ET(B) receptor antagonists. CONCLUSION The results of current clinical and experimental investigations support the hypothesis that ET-1 is a major cause of cerebral vasospasm after SAH. Other studies indicate that SAH causes complex changes in the ET system and increased ET-1 levels after SAH, which are not solely responsible for the development of vasospasm but may occur after cerebral ischemia. Further investigations are therefore needed to clarify these different hypotheses.

Abstract
The purpose of this study was to identity the trigger mechanism activating the 5-lipoxygenase pathway during blood-brain cell contact and to estimate the contribution of blood and brain cells to the cysteinyl-leukotriene (LT) biosynthesis observed under these conditions. Incubation of dissociated rat brain cells in Krebs-Henseleit solution for up to 60 min did not stimulate any detectable cysteinyl-LT biosynthesis. Incubation of recalcified rat whole blood in vitro for up to 60 min led to release of only small amounts of cysteinyl-LT into the serum samples. However, coincubation of dissociated rat brain cells with physiologically recalcified autologous whole blood triggered a time-dependent release of large amounts of immunoreactive cysteinyl-LT into the serum samples. By reverse-phase HPLC, immunoreactive cysteinyl-LT was identified as a mixture of LTC4, LTD4, and LTE4. The extent of the 5-lipoxygenase stimulation depended on the amount of autologous blood coincubated with the dissociated brain cells. Activation of the 5-lipoxygenase pathway also occurred with coincubation of dissociated rat brain cells with recalcified autologous plasma. Stimulation of cysteinyl-LT biosynthesis during blood-brain cell contact remained unaffected by aprotinin, but concentration-dependent inhibition by the structurally and functionally unrelated thrombin inhibitors D-Phe-Pro-Arg-CH2Cl and recombinant hirudin was seen. Finally, when dissociated rat brain cells were incubated in Krebs-Henseleit solution in the presence of human alpha-thrombin, a concentration-dependent release of cysteinyl-LT into the buffer samples was observed. These data demonstrate that, in rats, during blood-brain cell contact, stimulation of the 5-lipoxygenase pathway in brain cells proceeds via alpha-thrombin as effector molecule.

Abstract
CSF eicosanoid levels are raised following subarachnoid haemorrhage but not sufficiently to be vasoactive per se within the cerebral circulation. Rebleeding and intraventricular haemorrhage are two factors associated with a worse outcome after aneurysmal SAH. We have examined the effects of these two factors on the CSF levels of TXB2 (TXA2 metabolite), PG6-keto F1 alpha (prostacyclin metabolite), PGF2 alpha and PGE2 in 44 patients following subarachnoid haemorrhage. In 15 patients who had received no non-steroidal anti-inflammatory agent or dexamethasone, intraventricular haemorrhage increased the median levels of all four eicosanoids in ventricular CSF by 2.1-5.1-fold. In 4 patients who rebled, the CSF median levels of all four eicosanoids were raised up to 250-fold over the normal range. These concentrations are just sufficient to have cerebrovascular and neuromodulatory effects.

Abstract
Experimental delayed cerebral vasospasm was produced in 16 adult mongrel dogs by the "two-hemorrhage" method of intracisternal injections of autologous arterial blood. Group 1 was a control group. Group 2 was a treatment group that received an intravenous injection of ONO-1078, a novel potent leukotriene antagonist, once a day for 7 days just after the first cisternal injection of the blood. Angiography was performed on Days 0 and 7, and the cerebrospinal fluid levels of leukotriene C4 (LTC4) were measured on Days 0, 3, and 7. The cisternal levels of LTC4 increased after subarachnoid hemorrhage in both groups. But the cerebrospinal fluid levels of LTC4 in the treatment group were significantly lower than those in the control group (P less than 0.05). The angiographic vasospasm after subarachnoid hemorrhage was partially prevented with the treatment of intravenous injections of ONO-1078 (P less than 0.001). These results suggest that LTC4 may play a role in the pathogenesis of delayed cerebral vasospasm, directly or indirectly, and ONO-1078 may have a therapeutic effect on the prevention of the development of delayed cerebral vasospasm.

Abstract
We studied platelet function in 41 patients with subarachnoid hemorrhage who were randomized to receive either nimodipine or placebo in a double-blind fashion. Nimodipine was given to 21 patients, intravenously for 7-10 days and then orally until 21 days after the subarachnoid hemorrhage. The other 20 patients received placebo in a similar manner. Nimodipine did not significantly influence platelet aggregability. For the first 1-5 days after the subarachnoid hemorrhage, nimodipine treatment did not have any notable effect on adenosine diphosphate-induced platelet thromboxane B2 release, but a significant (p less than 0.05) inhibitory effect was observed thereafter. During intravenous administration, nimodipine prevented the increase in thromboxane release otherwise observed after subarachnoid hemorrhage. Concomitant with the decrease in thromboxane release, nimodipine increased the platelet count both before and after surgery so that the capacity for thromboxane formation per liter of blood decreased less than expected on the basis of thromboxane release per 10(7) platelets. Our study suggests that nimodipine might diminish the chance of cerebral ischemia by inhibiting platelet thromboxane release.

Abstract
The purpose of our study was to compare the ability of intraluminally and extraluminally administered nimodipine to inhibit serotonin-induced cerebral vascular responses in vitro and in situ. No difference was noted in the ability of nimodipine, whether administered intraluminally or extraluminally, to reduce the contractile response of extraluminally administered serotonin in a closed, pressurized, in vitro bovine middle cerebral artery preparation; histologic studies indicated that the tight endothelial junctions normally found in cerebral arteries remained intact in this preparation. In cats, pretreatment with nimodipine did not significantly reduce the ability of intracisternally injected serotonin to decrease cerebral blood flow; however, nimodipine did reduce the changes in cerebral artery diameter normally noted angiographically after serotonin injection. Although minor differences were noted between the intraluminal and extraluminal routes of administration of nimodipine in situ, in general the effects were comparable.

Abstract
Nimodipine, a calcium-channel antagonist with a relatively selective vasodilatory effect on cerebral blood vessels, has recently been approved for improvement of neurologic deficits due to spasm following subarachnoid hemorrhage. Nimodipine has low oral bioavailability (2.7-27.9 percent), a short half-life (2 h), is highly protein bound (98-99 percent), and is hepatically metabolized. Clinical studies have evaluated topical, intravenous, and oral administration of nimodipine for the treatment of cerebral artery spasm associated with subarachnoid hemorrhage. These studies document some benefit of the drug in reducing the occurrence of severe neurologic deficit, although this effect is not universal. Few adverse effects have been noted. Further studies are necessary to evaluate the pharmacologic and pharmacokinetic characteristics, the appropriate dose and route of administration, adverse effects, drug interactions, and the therapeutic efficacy of nimodipine before routine use can be recommended.
