PURPOSE: Preterm very low birth weight infant have high rate of adverse neurodevelopmental sequale. Recently, there have been lots of reports that human umbilical cord blood transplantation ameliorates functional deficits in animal models as hypoxic ischemic injury. This pilot study was undertaken to determine the clinical efficacy and safety of autologous umbilical cord blood cell transplantation for preventing neurodevelopmental sequale in perterm VLBW. METHODS: Subjects were 26 preterm infants whose birth weight are less than 1,500 g and delivered under the intrauterine period 34 weeks. Autologous umbilical mononuclear cells (about 5.87x10(7)/kg) were injected to neonate via the umbilical vein on the postnatal 24-48 hour. The therapeutic efficacy was assessed by numbers of nucleated RBC, urinary uric acid/creatinine ratio, concentration of neuron specific enolase (NSE), interleukin 6 (IL6), interleukin-1beta (IL-1beta), and glial cell derived neurotrophic factor (GDNF) in serum and cerebrospinal fluid on day 1 and 7. RESULTS: There were no significant differences in the numbers of the nucleated RBC, urinary uric acid/creatinine ratio, concentration of creatine kinase between the transplanted infants and controls. But the nucleated RBC is more likely to be rapidly discharged in the transplanted group. In the transplanted group, the concentrations of IL6, IL-1beta, and GDNF were no significant difference between day 1 and 7, although GDNF seemed to be elevated. Serum NSE concentration was significantly elevated after transplantation, but not in CSF. CONCLUSION: It is suggested that autologous umbilical cord blood transplantation in preterm very low birth weight infant is safe to apply clinical practice. Long term follow up study should be needed to evaluate the potential therapeutic effect of umbilical cord blood transplantation for neuroprotection.

Near-infrared spectroscopy is a device used to determine whether traumatic intracranial hemorrhage has occurred and is primarily used for screening in emergency situations. In this study we examined the applicability of this equipment in postmortem inspection. This study included 124 autopsy cases and 59 postmortem inspection cases performed in the National Forensic Service from July 2017 to October 2018. We carried out the test using Infrascanner Model 2000 (Infrascan Inc.). Autopsy cases were divided into four groups (epidural hemorrhage or subdural hemorrhage group, traumatic subarachnoid hemorrhage or cerebral contusion group, nontraumatic intracerebral hemorrhage group, and control group) and analyzed. There was no difference in the test results according to the presence and type of intracranial hemorrhage. The possibility that variables related to postmortem change affected the test results was considered. In conclusion, this study confirmed that near-infrared spectroscopy is not suitable for the detection of traumatic intracranial hemorrhage in postmortem inspection.
