  • Objectives: The study investigated the effect of Korean medicine treatment on a hemiplegic patient with conscious and cognitive disorders due to hemorrhagic transformation after interventional reperfusion therapy of anterior circulation infarction. Case presentation: The patient was treated with acupuncture, moxibustion, cupping, and herbal medicine in combination with Western medicine and physical therapy. The effects on clinical symptoms were evaluated using the Manual Muscle Test (MMT), Glasgow Coma Scale (GCS), Korean Mini-Mental State Examination (K-MMSE), Korean Nursing Delirium Screening Scale (Korean Nu-DESC), and Modified Bathel Index (MBI). After the treatment, the MMT grade increased from Gr.0-1 to Gr.0-3, the GCS score increased from 10 to 15, the K-MMSE score increased from 8 to 15, the Korean Nu-DESC score decreased from 3 to 1, night delirium disappeared, and the MBI score increased from 13 to 26. Conclusions: Complex Korean medicine treatments were effective for improving the clinical symptoms of hemorrhagic transformation after interventional reperfusion therapy for anterior circulation infarction in a patient with hemiplegia and conscious and cognitive disorders. However, further studies are needed.

  • Objective : Hemorrhagic transformation (HT) can be occurred after acute cerebral infarction. HT can worse symptoms in severe cases and adversely affect long-term prognosis. As bone and vascular smooth muscle are composed of type 1 collagen, we aimed to identify a potential relationship between bone mineral density (BMD) and HT after acute cardioembolic stroke. Methods : As an indicator of BMD, we used mean frontal skull Hounsfield unit (HU) values on brain computed tomography (CT). Multivariative hazard ratios were calculated using Cox regression analysis to identify whether the osteoporotic condition was an independent predictor of HT after acute cardioembolic stroke. Results : This 11-year analysis enrolled 506 patients who diagnosed as acute cardioembolic infarction. The first tertile of skull HU value was an independent predictor of HT development compared to the third tertile (hazard ratio, 2.12; 95% confidence interval, 1.13-3.98; p=0.020). We observed no interactions between age and skull HU with respect to HT statistically. Conclusion : The results of this study revealed an association between osteoporotic conditions and HT development after acute cardioembolic stroke. A convenient method to measure the cancellous bone HU value of the frontal skull using brain CT images may be useful for predicting HT in patients with acute cerebral infarction.

  • While a delayed intracerebral hemorrhage at the site of a ventricular catheter has occasionally been reported in literature, a delayed hemorrhage caused by venous infarction secondary to ventriculoperitoneal shunting has not been previously reported. In the present case, a 68-year-old woman underwent ventriculoperitoneal shunting through a frontal burr hole, and developed a hemorrhagic transformation of venous infarction on the second postoperative day. This massive venous infarction was caused by bipolar coagulation and occlusion of a large paramedian cortical vein in association with atresia of the rostral superior sagittal sinus. Thus, to eliminate the risk of postoperative venous infarction, technical precautions to avoid damaging surface vessels in a burr hole are required under loupe magnification in ventriculoperitoneal shunting.

  • Swine endothelial cells are commonly used as an in vitro model for studying features of the blood-brain barrier and some hemorrhagic diseases. However, primary cultures of swine cells have finite lifespans. To establish immortalized swine umbilical vein endothelial cells (SUVECs) using human telomerase reverse transcriptase (hTERT), the plasmid pCI-neo-hTERT was transfected into SUVECs by lipofection. Clones were selected for G418 resistance, and positive clones were amplified. One of the clones was cultured for up to 50 passages. Factor VIII-related antigen and CD34 were detected. The immortalized cells shared the properties of normal cells, such as contact inhibition, serum requirement and anchorage dependence. Karyotype analysis revealed that the immortalized cells were in the diploid range. In addition, both in vivo and in vitro assays of tumorigenicity showed no neoplastic transformation. Furthermore, NO, $PGI_2$, and ET-1 concentrations in the transfected cells were normal. These results suggest that the SUVECs immortalized by hTERT retain their original characteristics.

  • Susceptibility-weighted imaging (SWI) is well known for detecting the presence of hemorrhagic transformation, microbleeds and the susceptibility of vessel signs in acute ischemic stroke. But in some cases, it can provide the tissue perfusion state as well. We describe a case of a patient with hyperacute ischemic infarction that had a slightly hypodense, patchy lesion at the left thalamus on the initial SWI, with a left proximal posterior cerebral artery occlusion on a magnetic resonance (MR) angiography and delayed time-to-peak on an MR perfusion performed two hours after symptom onset. No obvious abnormal signals at any intensity were found on the initial diffusion-weighted imaging (DWI). On a follow-up MR image (MRI), an acute ischemic infarction was seen on DWI, which is the same location as the lesion on SWI. The hypointensity on the initial SWI reflects the susceptibility artifact caused by an increased deoxyhemoglobin in the affected tissue and vessels, which reflects the hypoperfusion state due to decreasing arterial flow. It precedes the signal change on DWI that reflects a cytotoxic edema. This case highlights that, in some hyperacute stages of ischemic stroke, hypointensity on an SWI may be a finding before the hyperintensity is seen on a DWI.

  • In order to use nervous necrosis virus (NNV) virus-like particles (VLPs) as a delivery tool for heterologous antigens or plasmids, we attempted to produce red-spotted grouper nervous necrosis virus (RGNNV) VLPs displaying a partial region of viral hemorrhagic septicemia virus (VHSV) glycoprotein at the surface and VLPs that are harboring DNA vaccine plasmids within the VLP. A peptide encoding 105 amino acids of VHSV glycoprotein was genetically inserted in the loop region of NNV capsid gene, and VLPs expressing the partial part of VHSV glycoprotein were successfully produced. However, in the transmission electron microscope analysis, the shape and size of the partial VHSV glycoprotein-expressing NNV VLPs were irregular and variable, respectively, indicating that the normal assembly of capsid proteins was inhibited by the relatively long foreign peptide (105 aa) on the loop region. To encapsulate by simultaneous transformation with both NNV capsid gene expressing plasmids and DNA vaccine plasmids (having an eGFP expressing cassette under the CMV promoter), NNV VLPs containing plasmids were produced. The encapsulation of plasmids in the NNV VLPs was demonstrated by PCR and cells exposed to the VLPs encapsulating DNA vaccine plasmids showed fluorescence. These results suggest that the encapsulation of plasmids in NNV VLPs can be done with a simple one-step process, excluding the process of disassembly-reassembly of VLPs, and NNV VLPs can be used as a delivery tool for DNA vaccine vectors.
