Abstract
BACKGROUND Eugenol has various curative properties. It affects the dilatation of cerebral arteries through voltage-dependent Ca2+ channel inhibition. This study is the first to explore the impact of eugenol on neuroprotection and vasospasm in an experimental subarachnoid hemorrhage (SAH) model. METHODS Twenty-four adult male Sprague-Dawley rats were indiscriminately separated into 3 groups: the control group (n = 8), the SAH group (n = 8), and the eugenol group (n = 8). A double-bleeding method was used. The eugenol group received intracisternal eugenol (Sigma-Aldrich, St. Louis, MO, USA) at 30 μg/20 μl after induction of SAH. On the day 7, all groups were euthanized. Measurements were taken for basilar artery wall thickness, lumen diameter, serum endothelin-1 (ET-1), and caspase-3 levels. RESULTS The eugenol group exhibited significantly lower wall thickness, ET-1, oxidative stress index, and caspase-3 levels compared to the SAH group. In comparison to the control group, the eugenol group showed a higher oxidative stress index along with higher ET-1 and caspase-3 levels, but these differences were not statistically significant. Wall thickness was significantly higher in the eugenol group than in the control group. CONCLUSIONS This study represents the first literature exploration of intrathecal eugenol's impact on vasospasm induced after experimental SAH. Administration of intrathecal eugenol demonstrates a positive effect on the treatment of experimental vasospasm as well as on the reduction of oxidative stress and apoptosis.

Abstract
The main reasons for disability and death in aneurysmal subarachnoid hemorrhage (aSAH) may be early brain injury (EBI) and delayed cerebral ischemia (DCI). Despite studies reporting and progressing when DCI is well-treated clinically, the prognosis is not well-improved. According to the present situation, we regard EBI as the main target of future studies, and one of the key phenotype-oxidative stresses may be called for attention in EBI after laboratory subarachnoid hemorrhage (SAH). We summarized the research progress and updated the literature that has been published about the relationship between experimental and clinical SAH-induced EBI and oxidative stress (OS) in PubMed from January 2016 to June 2021. Many signaling pathways are related to the mechanism of OS in EBI after SAH. Several antioxidative stress drugs were studied and showed a protective response against EBI after SAH. The systematical study of antioxidative stress in EBI after laboratory and clinical SAH may supply us with new therapies about SAH.

Abstract
BACKGROUND One of the antioxidant mechanisms is the dynamic balance between thiol and disulfide, which, in subarachnoid hemorrhage and other chronic diseases, is disrupted in favor of the latter. The two most commonly used oxidative stress (OS) biochemical markers are the oxidative stress index (OSI) value, which indicates the total oxidant status (TOS) and total antioxidant status (TAS) balance, and the thiol-disulfide (TDS) value, which indicates the total thiol (TT) and native thiol (NT) balance. High OS levels require further investigations. We aimed to investigate the OS level in aneurysmal SAH (aSAH) patients. METHODS In this clinical prospective study, blood samples were collected from 50 consecutively treated patients with aSAH and 50 volunteers. Serum TOS, TAS, TT, and NT levels were measured using Erel's method via a spectrophotometer. The Glasgow Coma Scale (GCS) scores, Fisher grades, length of hospital stay (LOS), and the Glasgow Outcome Scale (GOS) scores were recorded. Consequently, the OSI and TDS values were calculated in all participants. RESULTS A statistically significant difference was observed in the TAS, TOS, OSI, and TDS values between the aSAH patients and the controls. The TT and NT values were significantly lower in aSAH patients than in the controls. A correlation was identified between the OSI values and the GCS scores. Although a correlation was observed between the TDS values and the LOS, no correlation was found between the OSI and the TDS values. CONCLUSION The OSI and TDS, which are OS indicators, might serve as the additional objective nominal data to evaluate the treatment efficacy and follow-up for SAH patients. Moreover, decreasing the OSI values and increasing the TT values can be used as improvement indicators in the treated aSAH patients. If we can reduce the OS at the early stage of SAH, it could improve the prognosis by reducing both the morbidity and mortality rates. Further randomized investigations are required to prove the findings in this prospective study.

Abstract
OBJECTIVE We investigated the effects of different doses of pregabalin on the pathophysiologic changes in early brain injury after subarachnoid hemorrhage (SAH) in rats. METHODS Thirty-eight Wistar albino rats were divided into 4 groups: control (n = 8), SAH (n = 10), SAH plus 30 mg/kg/day of pregabalin (n = 10), and SAH plus 60 mg/kg/day of pregabalin (n = 10). SAH was induced with 0.3 mL of autologous blood injected to the cisterna magna of rats. Pregabalin was administered intraperitoneally. Oxidative stress markers, mRNA expression of endothelial nitric oxide synthase, hypoxia-inducible factor-1α, and vascular endothelial growth factor, and histopathological changes were evaluated. RESULTS Pregabalin increased mRNA expression of endothelial nitric oxide synthase, hypoxia-inducible factor-1α, and vascular endothelial growth factor in a dose-dependent manner. Significant improvement in the histopathological parameters was observed at 60 mg/kg, including a decrease in diffuse hemorrhagic areas, edema and apoptotic bodies in the associated cortical area, evident vacuolization in the hippocampal area, and apoptotic bodies. However, these improvements were not observed with the lower dose (30 mg/kg). In contrast, the antioxidant effect was greater with 30 mg/kg of pregabalin than with 60 mg/kg. CONCLUSIONS Although the antioxidant effect was significant with the lower dose of pregabalin, the anti-inflammatory effects via vasodilatation were more marked with the higher dose. Significant improvements in the histopathological changes were observed with the higher dose of pregabalin. The dose-dependent effects of pregabalin on SAH should be evaluated in animal studies as a function of time and in the acute and chronic phases.

Abstract
BACKGROUND The New Zealand White rabbit (NZWR) is the first small-animal experimental model of intra-arterial chemotherapy (IAC) for retinoblastoma treatment. The NZWR has dual ophthalmic arteries (OA): the external OA (EOA) arises from the external carotid artery and the internal OA (IOA) from the internal carotid artery. We describe the technique that we have refined for OA catheterization in rabbits, and describe the angioanatomical variations in the OA supply to the NZWR eye and implications for IAC delivery, which were identified as part of a larger project exploring IAC effects in a rabbit retinoblastoma model. METHODS We developed techniques to perform angiography of the external and internal carotid arteries and superselective angiography of the EOA and IOA in NZWR using transfemoral access and a microwire/microcatheter system. EOA and IOA supply to the eye was determined angiographically and recorded before selective OA catheterization and angiography. RESULTS 114 rabbits underwent carotid angiographic evaluation and OA catheterization (161 total eyes evaluated, 112 right, 49 left). Most eyes had a single dominant arterial supply; either IOA or EOA. EOA was dominant in 73% (118/161), and IOA was dominant in 17% (27/161). Co-dominant supply was seen in 10% (16/161). Of the rabbits with bilateral OA catheterization, 25/47 (53%) had bilateral dominant EOA. CONCLUSION Successful catheterization of the OA in the NZWR can be readily accomplished with nuanced technique. The external OA is the dominant arterial supply in the majority of NZWR eyes. These findings allow for successful reproduction of OA catheterization studies of IAC for retinoblastoma in NZWR.

Abstract
UNLABELLED The first results of intracisternal administration of verapamil for the prevention and treatment of cerebral vasospasm (CVS) in patients in the acute period of subarachnoid hemorrhage (SAH) after microsurgical clipping of cerebral aneurysms are presented. OBJECTIVE Safety assessment of the method of prolonged intracisternal infusion (PII) of verapamil. MATERIAL AND METHODS Over the period from May 2017 to December 2018, 42 patients were included in the study, who underwent clipping of aneurysm of the anterior segments of the Willis circle. Most patients (78.6%) were operated during the first 6 days after SAH. For each patient, a thin silicone catheter was installed, through which verapamil was infused. A prerequisite was the installation of external ventricular drainage and opening of the lamina terminalis. The daily dosage of verapamil varied from 25 to 50 mg of the drug diluted in 200-400 ml of isotonic sodium chloride solution. The indication for the use of the PII method was the presence of one of the following factors: a score on the Hunt-Hess scale from III to V, 3 or 4 points on the Fisher scale, confirmed angiographically by the CVS before the operation. RESULTS The PII procedure was performed from 2 to 5 days. The average dose of verapamil was 143.5±41.2 mg additionally, in the presence of an angiographically confirmed CVS accompanied by clinical manifestations, 14 (33.4%) patients received intra-arterial injection of verapamil in several stages, with individual selection of the drug dose. The formation of new cerebral ischemic foci of vasospastic genesis was observed in only 1 (2.4%) patient. No infectious intracranial complications were noted. The average follow-up period was 297.6±156.1 days. Long-term treatment outcomes, assessed by a modified Rankin scale from 0 to 2 points, were observed in 83.3% of patients. There were no outcomes such as vegetative status and no deaths. The frequency of liquorodynamic disorders, as well as epileptic syndrome did not exceed that among patients with SAH according to the literature. CONCLUSION The study has confirmed the safety of prolonged PII. The efficacy of the method, compared with other methods for CVS treatment requires further investigation. The first results look quite promising: the observation shows a low percentage of new foci of cerebral ischemia and the absence of deaths associated with it. In patients with severe CVS, the efficacy of the PII method is increased when combined with intra-arterial administration of verapamil.
