  • We present a fatal case of cerebral arterial thrombosis after corona virus disease 19 (COVID-19) vaccination with ChAdOx1 nCOV-19. The deceased was a 63-year-old woman with no relevant medical history. She presented symptoms of nausea, fatigue, and headache immediately after vaccination. Ten days after vaccination, she suddenly started vomiting and developed high blood pressure. The patient eventually died 23 days after vaccination. Autopsy findings showed that the cerebral arteries and internal carotid arteries were fully enlarged and were compacted with thrombi. The brain stem showed ischemic necrosis, and extravasation from this necrotic lesion led to focal subarachnoid hemorrhage around the brain stem where large blood clots still remained. No aneurysms or atherosclerotic changes were found in these arteries. We note the following three facts. Firstly, all symptoms occurred immediately after vaccination; secondly, the main cause of death was consistent with known side effects of the vaccine; and lastly, the mechanism of thrombus formation in this case goes beyond the general category of thrombogenesis known so far. While the authors know that this case does not fall into known categories of vaccine side effects, we presenting this case to demonstrate that a comprehensive review of various possibilities related to vaccine side effects is needed to establish a COVID-19 defense system.

  • Purpose: To examine effects of application of bronchodilators after endotracheal suction on peak air way pressure (PAP), lung compliance (Cdyn), oxygen saturation ($SpO_2$), heart rate (HR), blood pressure (BP), and respiration rate (RR) in cardiac surgery patients. Method: Data were collected from October 2007 to March 2008. Participants were patients who were treated with bronchodilators through mechanical ventilators in the SICU. At each suctioning, bronchodilators were applied immediately, and at 5, 10, and 15 minutes after suctioning. Besides PAP, Cdyn, $SpO_2$, HR, BP, RR, data on the frequency of side effects were also collected at 15, 30, 60 minutes after nebulization. Data were analyzed using the SAS program. Results: For application of bronchodilator right after suctioning and after, 5, 10 and 15 minutes, PAP and Cdyn did not show any significant differences although PAP was persistently decreased for 15 to 30 minutes and Cdyn increased at 15 minutes and decreased gradually after nebulization. Besides $SpO_2$, HR, BP, and RR, frequency of side effects did not show any significant difference. Conclusion: Bronchodilators can be applied at any time. However, the positive effects of bronchodilation right after suctioning on PAP and Cdyn, as also shown in previous reports, indicate it is a more efficient clinical process to maintain an adequate airway.

  • Dielectric constant of ferroelectric ceramics with poling is important in relation to the mechanism of dielectric breakdown. From the research about the dielectric constant variation with poling in tetragonal and rhombohedral phase PZT ceramics, it is known that the dielectric constant after poling is determined by competing effects between increasing effects (compressive stress induced by electrostriction of piezoelectric effects) and decreasing increase in large grain size with poling is smaller than in small grain size.

  • Background: In view of the safety and effectiveness of butorphanol as a postoperative analgesic, we designed to compare its activity and side effects with those of ketoprofen, when administered intramuscularly. Methods: Ninety four patients, scheduled for elective total abdominal hysterectomy, received either ketoprofen 100 mg (ketoprofen group) or butorphanol 2 mg (butorphanol group) intramuscularly after surgery. For the first six hours after injection of butorphanol or ketoprofen, the patients were asked to reevaluate the intensity of pain, using numeric rating scale (NRS) and pain score. If the pain score was above 2, supplemental ketoprofen was administered IM. Incidence of side effects were also checked. Results: Butorphanol group showed lower NRS and pain score for the first four hours compared to ketoprofen group, but the incidence of drowsiness was higher in butorphanol group. There were no significant difference in the incidence of other side effects such as nausea and dizziness. In both group, there were neither respiratory depression nor pruritus. Conclusions: Butorphanol gave better relief of postoperative pain compared to ketoprofen. Butorphanol might be a useful drug for postoperative analgesia after hysterectomy with minor side effects.

  • Purpose: The Purpose of this study was to evaluate the effects of antioxidant vitamins and minerals supplementation on blood pressure and lipids in the elderly with hypertension. Methods: This study adopted a unequivalent control group pretest-posttest design. For this study, 79 subjects with hypertension were selected among the home visiting clients of public health centers. The experimental group received 12-weeks' treatment with antioxidant vitamin A, C, E, carotene, magnesium and selenium and the control group did not take any antioxidant vitamin and mineral. Results: There were statistical differences in systolic blood pressure and diastolic blood pressure between the experimental group and the control group after the intervention. In the experimental group, systolic blood pressure decreased from 145.4mmHg before the intervention to 135.7mmHg after the intervention, and diastolic blood pressure decreased from 88.3mmHg before the intervention to 81.9mmHg after the intervention. However, there were no statistical differences in total cholesterol and triglyceride between the experimental group and the control group after the intervention. Conclusions: A short-term supplementation with antioxidant vitamins & minerals can reduce blood pressure in the elderly with hypertension. The continuous effects of the supplementation and its beneficial effects on the prevention of cardiovascular diseases still need to be studied further.

  • Clonidine, an antihypertensive drug, stimulates postsynaptic alpha-2 adrenergic receptors in the central nervous system and lowers arterial pressure through the effects on both cardiac output and peripheral resistance. However, many patients experience that sedation and xerostomia occur upon oral administration of clonidine. These side effects are due to high plasma peak concentration and can be avoided when clonidine is given transdermally. In this study, we tested the antihypertensive effects of trandermal administration of clonidine patch on spontaneously hypertensive rat (SHR) which is a model animal for human essential hypertension. Forty eight SHR (male) were divided into six groups according to the dose levels, respectively. After transdermal administration of clonidine patch of each dose, systolic blood pressure and heart rate were measured. Clonidine patch produced maximal antihypertensive and bradycardiac effects 48 hrs after administration and antihypertensive effects showed dose-dependency. We suggest that antihypertensive effects of clonidine patch are similar to those of orally given clonidine and clonidine patch can be used instead of clonidine tablet.
