  • Objective: Prompt diagnosis and management are essential for saving the adnexal organs from infarction in cases of ovarian torsion (OT). This study aimed to determine the diagnostic significance of signal peptide, complement C1r/C1s, Uegf, and Bmp1 (CUB), and epidermal growth factor-like domain-containing protein-1 (SCUBE-1) levels in cases of OT, an emergent ischemic condition, and the relationship of SCUBE-1 with oxidative stress parameters. Methods: This prospective study was conducted among 15 OT patients and 20 age- and gravidity-matched healthy women. SCUBE-1 serum concentrations were determined by using enzyme-linked immunosorbent assays. In addition, oxidative stress was evaluated by measuring the serum levels of advanced oxidation protein products (AOPP), ferric reducing ability of plasma (FRAP), and glutathione (GSH). Results: The SCUBE-1 titers were significantly higher in the patients with OT than in the controls (p=0.008). In addition, serum FRAP and GSH levels were significantly lower in the OT patients than in the controls (p<0.001 for both). Serum AOPP levels were higher in the OT patients, but this trend was not statistically significant (p>0.05). Furthermore, there were no correlations between SCUBE-1 levels and age, gravidity, parity, cyst size, and AOPP, FRAP, or GSH levels (p>0.05). Conclusion: We believe that SCUBE-1 may be a promising biomarker for the early diagnosis of OT.

  • Background : Vascular dementia occurs mainly due to cerebral vascular disease. So we performed this clinical study to investigate the incidence and characteristics of vascular dementia in stroke patients. Methods : This study was performed on the patients hospitalized from April 1, 1998 to August 31, 1998 at the department of circulatory internal medicine, hospital of Oriental medicine, Kyung-Hee University, and diagnosed cerebral infarction or hemorrhage by Brain CT or MRI. we devided the patients into two groups; vascular dementia group and non dementia group according to MMSE-K(Mini Mental State Examination Korean version), Hasegawa dementia scale. Patients were diagnosed dementia using DSM-IV. We compared general characteristics, stoke types and laboratory findings between the two groups and investigated the correlationship between MMSE-K and Hasegawa dementia scale. Results : Results showed that the incidence of vascular dementia was about 27.8% in stroke patients. The greater number of subjects with dementia were women in the lower educational classes and had lower MBI(Moderfied Bathel Index) scores. Vascular dementia were more common in patients with large brain lesion size($>20cm^3$). There was a positive correlationship between Hasegawa scores and MMSE-K.

  • The normal intracranial structures are relatively resistant to therapeutic radiation, but may react adversely in a variety of ways, and the damage to nerve tissue may be slow in making its appearance, and once damage has occured the patient recovers slowly and incompletly. Therefore, it is important to consider the possibility of either recurrent tumor or late adverse effect in any patient who has had radiotherapy. The determination o( rnorphological/pathological correlation is very important to the therapeutic radiologist who uses CT scans to define a treatment volume, as well as to the clinician who wishes to explain the patient's clinical state in terms of regress, progression, persistence, or recurrence of tumor or radiation-induced edema or necrosis, The authors are obtained as following results ; 1. The field size(whole CNS, large, intermediate, small field) was variable according to the location and extension of tumor and histopathologic diagnosis, and the tatal tumor dose was 4,000 to 6,000 rads except one of recurred case of 9,100 rads. The duration of follow up CT scan was from 3 months to 5 year 10 months. 2, The histopathologic diagnosis of 9cases were glioblastoma multiforme(3 cases), pineal tumor (3), oligodendroglioma (1), cystic astrocytoma (1), pituitary adenoma (1) and their adverse effects after radiation therapy were brain atrophy (4 cases) , radiation necrosis(2), tumor recurrence with or without calcification (2), radiation·induced infarction (1). 3. The recurrent symptoms after radiation therapy of brain tumor were not always the results of regrowth of neoplasm, but may represent late change of irradiated brain. 4. It must be need that we always consider the accurate treatment planning and proper treatment method to reduce undesirable late adverse effects in treatment of brain tumors.

  • Neurosyphilis is a rare infection of the brain and spinal cord caused by a spirochete named Treponema pallidum. We describe the magnetic resonance imaging of a 53-year-old man with syphilis who manifested as both meningovascular, and spinal meningomyelitic types, which involved the optic, trigeminal, facial and vestibulocochlear nerves, both middle and left posterior cerebral arteries, thoracic spinal cord and meninges of the lumbar spine. This case report suggests that neurosyphilis should be considered as a possible diagnosis in patients showing complex brain and spinal imaging features. These features include enhancing meningeal lesions with multiple cranial nerve involvement, stenoses in large to medium size cerebral arteries, and intramedullary and meningeal lesions of spine.

  • Ischemic stroke constitutes about 80% of all stroke incidences. It is characterized by brain cell death in a region where cerebral arteries supplying blood are occluded. Under these ischemic conditions, apoptosis is responsible for the cell death, at least in part. Goat's-beard (Aruncus dioicus var. kamtschaticus) is a perennial plant that grows naturally in the alpine regions of Korea. In the present study, we first determined whether water extract of goat's-beard (HY1646) and some of its fractions prepared by partitioning with organic solvents could improve the viability of human hepatocellular carcinoma cells (HepG2) cultured under hypoxic condition by blocking apoptotic pathways. Based on the in vitro findings, we subsequently investigated whether HY1646 and the ethyl acetate fraction (EA) selected from cell culture-based screening could attenuate brain injury in a rat middle cerebral artery occlusion (MCAO) model of ischemia (2 hr), followed by 22 hours of reperfusion. The cell number was sustained close to that initially plated in the presence of HY1646 even after 24 hr of cell culture under hypoxic condition (3% $O_2$), at which time the cell number reached almost zero in the absence of HY1646. This improvement in cell viability was attributed to the delay in apoptosis, identified by the formation of DNA ladder in gel electrophoresis. Of fractions soluble in hexane, ethyl acetate (EA) and butanol, EA was chosen for the animal experiments because EA demonstrated the best cell viability at the lowest concentration (10 ${\mu}g$/mL). HY1646 (200 mg/kg) and EA (10 and 20 mg/kg) significantly reduced infarct size, an index of brain injury, by 16.6, 40.0 and 61.0%, respectively, as assessed by 2,3,5-triphenyl tetrazolium chloride staining. The findings suggest that prophylactic intake of goat's beard might be beneficial for preventing ischemic stroke.

  • One of the treatments and preventions of strokes such as ischemic stroke is to increase cerebral blood flow. This aims to minimize the size of the stroke by increasing the quantity of blood to the cerebral region circuitously. Several ways to increase cerebral blood flow are a therapy though drugs and through surgery. However these invasive method giving a burden to the patient, the problem of inducing a number of complications were noted. In this thesis, we propose a non-invasive brain flow enhancer to complement the disadvantages of such invasive treatment methods. To compensate for the shortcomings of the existing devices, the patient's blood pressure is accurately measured and the blood pressure is applied to the extremities, thereby increasing blood flow to the femoral region to produce blood clotting treatments. Although somewhat inadequate blood flow increases compared to conventional devices, blood flow can be significantly increased, which can be selectively.

  • Ischemic stroke, a major cause of death and disability worldwide, is caused by occlusion of cerebral arteries that, coupled with or without reperfusion, results in prolonged ischemia (hypoxia and hypoglycemia) and, ultimately, brain damage. In this study, we examined whether methanol extract of the whole plant of Cassia mimosoides var. nomame Makino that grows naturally in Korea, as well as Japan and China, and some of its fractions obtained by partitioning with organic solvents could protect human hepatocellular carcinoma cells (HepG2) under hypoxic condition by inhibiting apoptosis. We also investigated if these extracts could attenuate brain damage in a rat model of 2 hr of ischemia, generated by middle cerebral artery occlusion, and 22 hr of reperfusion. The whole extract ($100{\mu}g$/mL) maintained the cell number at more than half of that initially plated, even after 24 hr of cell culture under hypoxic condition (3% $O_2$). In the absence of the whole extract, almost all of the cells were dead by this time point. This improvement of cell viability came from a delay of apoptosis, which was confirmed by observing the timing of the formation of a DNA ladder when assessed by gel electrophoresis. Of fractions soluble in hexane, ethyl acetate (EA), butanol and water, EA extracts were selected for the animal experiments, as they improved cell viability at the lowest concentration ($10{\mu}g$/mL). The whole extract (200 mg/kg) and EA extract (10 and 20 mg/kg) significantly reduced infarct size, a measure of brain damage, by 34.7, 33.8 and 45.2.0%, respectively, when assessed by 2,3,5-triphenyl tetrazolium chloride staining. The results suggest that intake of Cassia mimosoides var. nomame Makino might be beneficial for preventing ischemic stroke through inhibition of brain cell apoptosis.

  • The purpose of this study is to report the effect of the Korean acupuncture treatment and Open Wet Dressing Therapy(OPWT) for pressure ulcer. From November 2015 to January 2020, 9 patients with 3rd or 4th graded pressure ulcer over 70 years of age who were admitted to a care hospital with underlying diseases such as cerebral infarction, brain hemorrhage, and Parkinson's disease were treated by acupuncture and OPWT. Photographs of lesions were used to evaluate the changes in condition of pressure ulcer. Acupuncture was performed 4 times a week along the border between the normal epidermal region and the pressure ulcer granulation tissue in contact with the pressure ulcer interface. OPWT to create a wet environment for wounds by washing the wounds 1-2 times a day with normal saline solution and covering them with food wrap was combined. In addition, for objective treatment progress evaluation, size, stage and condition of pressure ulcer were regularly monitored using the classification method of The National Pressure Ulcer Advisory Panel (NPUAP) according to the condition and depth of the damaged tissue and The Pressure Ulcer Scale for Healing(PUSH tool 3.0). After acupuncture treatment and OPWT, the pressure ulcer of patients was cured in as short as 66 days and as long as 274 days (average 170 days). This study shows that acupuncture treatment and OPWT were effective to treat pressure ulcer.

  • Background: Carotid endarterectomy (CEA) is used to treat carotid stenosis, which is associated with cerebral infarction and may result in neurologic deficits such as stroke, transient ischemic attack (TIA), and local nerve injury. To decrease surgery-related complications and improve patient satisfaction with esthetic outcomes, efforts have been made to minimize incision size instead of using a standard longitudinal incision. Methods: We performed a retrospective analysis of 151 cases of CEA, of which 110 used conventional incisions and 41 used high mini-skin incisions (HMIs), from March 2015 to December 2021 at a single institution. Short-term (30-day) postoperative results were evaluated for rates of mortality, stroke, TIA, and cranial/cervical nerve injuries. Risk factors for nerve injury were also assessed. Results: The HMI group showed significantly (p<0.01) shorter operative and clamp times than the conventional group. The HMI group also had significantly shorter incision lengths (5.3±0.9 cm) than the conventional group (11.5±2.8 cm). The rates of stroke, TIA, and death at 30 days were not significantly different between the 2 groups. There was no significant difference in the rate of cranial and cervical nerve injuries, and all injuries were transient. A high lesion level (odds ratio [OR], 9.56; 95% confidence interval [CI], 3.21-28.42; p<0.01) and the clamp time (OR, 1.07; 95% CI, 1.03-1.12; p<0.01) were found to be risk factors for nerve injuries. Conclusion: Use of the HMI in CEA for carotid stenosis was advantageous for its shorter operative time, shorter internal carotid artery clamp time, reduced neurologic complications, and improved esthetics.
