  • Objective : The inappropriate or excessive apoptosis has been known to be associated with neurodegenerative disorders including intracranial hemorrhage(ICH). Paeoniae radix, in traditional Korean medicine, has played its role as blood­nourisher and yin-astringent. In the present study, the effect of Paeoniae radix on the inhibition of neurodegeneration in the brain of rats after artificial ICH and on the resulting apoptosis was investigated. Methods : 30 rats were divided into 6 equal groups ; the sham-operation group, the hemorrhage-induction group, the hemorrhage-induction with 10, 50, 100, and 200 mg/kg Paeoniae radix-treated group, respectively. Stereotactic surgery was performed and collagenase was infused to induce ICH in the region of CA1 of hippocampus of rats. The sham group took only saline infusion. For 7 days after the surgery, 4 testing groups had intraperitoneal injections of Paeoniae radix extract. The step-down inhibitory avoidance task, measurement of neurodegeneration degree in the CA1 region of the hippocampus, and detection of caspase-3 and newly generated cells in the dentate gyrus were done after animal sacrifice. Results : Rats receiving Paeoniae radix extract showed increased latency time in the inhibitory avoidance task. The extension of neuron-deprived areas in the CA1 region was significantly suppressed in the Paeonia treated groups. Also expressions of caspase-3 in the CA1 region and cortex were significantly inhibited in the Paeonia treated groups. The cell proliferation was evaluated by means of BrdU methods and proved to be decreased in the Paeonia treated groups. Conclusion : These results suggest that Paeoniae radix has potential to suppress short-tenn memory loss after devastating neurologic accidents. Also it was proved that Paeoniae radix has a neuroprotective effect and alleviates central nervous complications following intracerebral hemorrhage. Furthermore, it may imply that this medicinal plant can be widely used for vascular dementia and other neurodegenerative disorders.

  • Objectives : ICH breaks down blood vessels within the brain parenchyma, which finally leads to neuronal loss, drugs to treat ICH have not yet been established. In this experiment, we measured the effect of Woowhangchongshim-won (WWCSW) on intracerebral hemorrhage (ICH) in rat using microarray technology. Methods : We measured the effect of WWCSW on ICH in rat using microarray technology. ICH was induced by injection of collagenase type IV, and total RNA was isolated. Image files of microarray were measured using a ScanArray scanner, and the criteria of the threshold for up- and down-regulation was 2 fold. Hierarchical clustering was implemented using CLUSTER and TREEVIEW program, and for Ontology analysis. GOSTAT program was applied in which p-value was calculated by Chi square or Fisher's exact test based on the total array element. Results : WWCSW-treatment restored the gene expression altered by ICH-induction in brain to the levels of 76.0% and 70.1% for up- and down-regulated genes, respectively. Conclusion : Co-regulated genes by ICH model of rat could be used as molecular targets for therapeutic effects of drug including WWCSW. That is, the presence of co-regulated genes may represent the importance of these genes in ICH in the brain and the change of expression level of these co-regulated genes would also indicate the functional change of brain tissue.

  • Objective : The purpose of this study was to investigate the prognostic factors in patients who suffered an intracerebral hemorrhage(ICH) due to a ruptured middle cerebral artery(MCA) aneurysm. Methods : Among 148 case of ruptured MCA aneurysm, ruptured MCA aneurysm with ICH was compared with ruptured MCA aneurysm alone. According to factors, the prognosis in these two groups was analyzed. Prognosis was evaluated postoperatively by applying Glasgow Outcome Scale(GOS) at discharge. Prognostic factors were evaluated with Chi square test, Mann-Whitney test and ANOVA test with differences being considered significant for value less than 0.05. Results : Ruptured MCA aneurysm alone revealed better consciousness on admission and final outcome than those combined with ICH. Ruptured MCA aneurysm alone showed 74% in H-H grade I, II and 82% in GOS I, II. But ruptured MCA aneurysm with ICH showed 63% in H-H grade IV, V and 52% in GOS IV, V. Age, sex, lesion site, aneurysmal size, temoporary clipping time, interval to operation, operative approach were statistically not significant in prognosis(p>0.05). But H-H grade on admission(p<0.05), complication(esp. cerebral infarction)(p<0.05), preoperative ICH volume and site(p<0.01), preoperative midline shifting(p<0.01), remained ICH volume(p<0.05) showed significance statistically. Conclusion : Prognostic factors are helpful to neurosurgeon to estimate clinical and neurological outcome postoperatively. We suggest that the good prognostic factors in ruptured MCA aneurysm with ICH were good H-H grade on admission, cerebral infarction(-), preoperative ICH volume <25cc, temporal and intrasylvian ICH, preoperative midline shifting <5mm, remained ICH volume <10cc.

  • Objective : An advantage of surgical treatment over conservative treatment of spontaneous intracerebral hemorrhage (ICH) is controversial. Recent reports suggest that contrast extravasations on CT angiography (CTA) might serve as a crucial predictor of hematoma expansion and mortality. The purpose of this study was aimed at investigating the efficacy of surgical treatment in patients with spot sign positive ICH. Methods : We used our institutional medical data search system to identify all adult patients who admitted for treatment of ICH between January 1, 2007 and January 31, 2012. Patients were classified two groups into a surgical group (n=27) and a conservative treatment group (n=28). Admission criteria were the following: age 20-79 years, spontaneous supratentorial ICH, Glasgow Coma Score Ranging from 9 to 14, ICH volume ${\geq}20mL$, and treatment within 24 hours. Results : Fifty-five patients were analyzed. There was no significant difference in the ICU stay between the conservative treatment group ($7.36{\pm}3.66days$) and the surgical treatment group ($6.93{\pm}2.20days$; p=0.950). There was a significant difference in the in-hospital stay between the conservative treatment group ($13.93{\pm}8.87days$) and the surgical treatment group ($20.33{\pm}6.37days$; p=0.001). Overall mortality at day 90 after ICH was 36.4%; this included 16 of 28 patients (57.1%) in the conservative group and 4 of 27 patients (14.8%) in the surgical group. In univariate analysis, there was a positive effect of the surgical treatment in reducing mortality at 90 days (p=0.002), Glasgow Outcome Scale (GOS) at 90-day (p=0.006), and modified Rankin Scale (mRS) at 90-day (p=0.023). In multivariate logistic analysis, there was a significant difference in mortality (odds ratio, 0.211; 95% confidence interval, 0.049-0.906; p=0.036) between the groups at 90-day follow-up. However, there was no significant difference in GOS (odds ratio, 0.371; 95% confidence interval, 0.031-4.446; p=0.434) and mRS (odds ratio, 1.041; 95% confidence interval, 0.086-12.637; p=0.975) between the groups at 90-day follow-up. Conclusion : In this study of surgical treatment of supratentorial ICH in patients with spot sign positive in CTA was associated with less mortality despite of long duration of in-hospital stay. We failed to show that clinical outcome benefit of surgical treatment compared with conservative treatment in patients with spot sign positive ICH.

  • Objectives : This study aimed at evaluation of the effects of Rhodiola rosea on brain edema and expressions of matrix metalloproteinases (MMPs) related to blood-brain barrier (BBB) disruption. Methods : Brain edema following intracerebral hemorrhage (ICH) was induced by the stereotaxic intrastriatal injection of bacterial collagenase type VII in rats (Sprague-Dawley). Then ethanol extract of Rhodiola rosea was treated once a day for 3 days. Brain edema % and water contents, and BBB leakage were examined. Immunohistochemistry was processed for MMP-9, MMP-12, and iNOS expressions in the brain sections and each immuno-labeled cells were analyzed with image analysis software. Results : 1. Ethanol extract of Rhodiola rosea reduced brain edema following ICH in rats significantly. 2. Ethanol extract of Rhodiola rosea reduced excessive brain tissue water contents following ICH in rats significantly. 3. Ethanol extract of Rhodiola rosea reduced BBB leakage in the cerebral cortex following ICH in rats. 4. Ethanol extract of Rhodiola rosea reduced cellular edema of neurons in peri-hematoma and the cerebral cortex following ICH in rats significantly. 5. Ethanol extract of Rhodiola rosea reduced MMP-9 positive cells in the cerebral cortex following ICH in rats significantly. 6. Ethanol extract of Rhodiola rosea reduced MMP-12 positive vessels in the cerebral cortex following ICH in rats significantly. 7. Ethanol extract of Rhodiola rosea reduced iNOS positive cells in the cerebral cortex and external capsule following ICH in rats significantly. Conclusions : These results suggest that Rhodiola rosea reveals protective effect against brain edema and cytotoxic edema of neurons by means of down-regulation of MMPs and iNOS expressions, and inhibition of BBB leakage.

  • Objectives: The aim of this study is to describe the effects of traditional Korean medicine treatment on a patient with an intracerebral hemorrhage (ICH) at the left basal ganglia, thalamus, and posterior limb of the internal capsule. Methods: The patient was treated with acupuncture, moxibustion, Hyangsayukgunja-tang, and Samul-tang-gami. The effect of these treatments were evaluated using the manual muscle test (MMT), modified Barthel index (MBI), and National Institutes of Health Stroke Scale (NIHSS). Results: After the treatments, the patient's status improved, as shown by his MMT grade, which increased from 1/1 to 4/4. In addition, the patient's MBI score improved from 0 to 77, and his NIHSS score declined from 16 to 2. In addition, the patient's Levin tube and Foley catheter were removed. Conclusion: The results suggest that traditional Korean medicine may be effective in the treatment of patients with ICH.

  • Objective : The spot sign is related with the risk of hematoma expansion in spontaneous intracerebral hemorrhage (ICH). However, not all spot sign positive patients undergo hematoma expansion. Thus, the present study investigates the specific factors enhancing the spot sign positivity in predicting hematoma expansion. Methods : We retrospectively studied 316 consecutive patients who presented between March 2009 to March 2011 with primary ICH and whose initial computed tomography brain angiography (CTA) was performed at our Emergency Department. Of these patients, 47 primary ICH patients presented spot signs in their CTA. We classified these 47 patients into two groups based on the presence of hematoma expansion then analyzed them with the following factors : gender, age, initial systolic blood pressure, history of anti-platelet therapy, volume and location of hematoma, time interval from symptom onset to initial CTA, spot sign number, axial dimension, and Hounsfield Unit (HU) of spot signs. Results : Of the 47 spot sign positive patients, hematoma expansion occurred in 26 patients (55.3%) while the remaining 21 (44.7%) showed no expansion. The time intervals from symptom onset to initial CTA were $2.42{\pm}1.24$ hours and $3.69{\pm}2.57$ hours for expansion and no expansion, respectively (p=0.031). The HU of spot signs were $192.12{\pm}45.97$ and $151.10{\pm}25.14$ for expansion and no expansion, respectively (p=0.001). Conclusions : The conditions of shorter time from symptom onset to initial CTA and higher HU of spot signs are the emphasizing factors for predicting hematoma expansion in spot sign positive patients.

  • Objective: To determine whether noncontrast computed tomography (NCCT) models based on multivariable, radiomics features, and machine learning (ML) algorithms could further improve the discrimination of early hematoma expansion (HE) in patients with spontaneous intracerebral hemorrhage (sICH). Materials and Methods: We retrospectively reviewed 261 patients with sICH who underwent initial NCCT within 6 hours of ictus and follow-up CT within 24 hours after initial NCCT, between April 2011 and March 2019. The clinical characteristics, imaging signs and radiomics features extracted from the initial NCCT images were used to construct models to discriminate early HE. A clinical-radiologic model was constructed using a multivariate logistic regression (LR) analysis. Radiomics models, a radiomics-radiologic model, and a combined model were constructed in the training cohort (n = 182) and independently verified in the validation cohort (n = 79). Receiver operating characteristic analysis and the area under the curve (AUC) were used to evaluate the discriminative power. Results: The AUC of the clinical-radiologic model for discriminating early HE was 0.766. The AUCs of the radiomics model for discriminating early HE built using the LR algorithm in the training and validation cohorts were 0.926 and 0.850, respectively. The AUCs of the radiomics-radiologic model in the training and validation cohorts were 0.946 and 0.867, respectively. The AUCs of the combined model in the training and validation cohorts were 0.960 and 0.867, respectively. Conclusion: NCCT models based on multivariable, radiomics features and ML algorithm could improve the discrimination of early HE. The combined model was the best recommended model to identify sICH patients at risk of early HE.

  • A 51-year-old woman presented with sudden severe headache, vomiting, and right hemiparesis at first admission. Computed tomography(CT) scans revealed an hemorrhagic density at left basal ganglia. Preoperative cerebral angiography showed no vascular lesion. Under the diagnosis of hypertensive intracerebral hemorrhage(ICH), total extirpation of hematoma was done. The postoperative neurological condition improved gradually and discharged without any neurological sequelae. Two months later, she revisited with headache, vomiting and progressive right hemiparesis. CT scans at second admission showed an irregular rim enhanced mass with central low density with surrounding edema at the initial bleeding area. Repeated craniotomy was performed and the mass was partially removed. The histopathological diagnosis of the specimen was confirmed as glioblastoma. The authors report a glioblastoma, which occurred at initial ICH site and regarded as a brain abscess with literature review.

  • Few studies have reported the effects of traditional Korean medical (TKM) therapy in patients with traumatic brain hemorrhage. The patient was a 93-year-old female who was unconscious after a traumatic intracerebral hemorrhage (ICH) and was not a candidate for any surgical treatment because of her age. We treated her with acupuncture and herbal medicine. After 28 days of treatment, we observed an improvement in consciousness on the Glasgow Coma Scale (GCS) and in other symptoms (aphasia, weakness in both legs, and headache).
