Purpose: The purpose of this study was to determine whether a higher Injury Severity Score (ISS) could serve as an indicator of splenectomy in patients with traumatic splenic lacerations. Methods: A total of 256 cases of splenic laceration were collected from January 1, 2005 to December 31, 2018. After the application of exclusion criteria, 105 were eligible for this study. Charts were reviewed for demographic characteristics, initial vital signs upon presentation to the emergency room, Glasgow Coma Scale, computed tomography findings, ISS, and treatment strategies. The cases were then divided into nonsplenectomy and splenectomy groups for analysis. Results: When analyzed with the chi-square test and t-test, splenectomy was associated with a systolic blood pressure lower than 90 mmHg, a Glasgow Coma Scale score lower than 13, active bleeding found on computed tomography, a splenic laceration grade greater than or equal to 4, and an ISS greater than 15 at presentation. However, in multivariate logistic regression analysis, only active bleeding on computed tomography showed a statistically significant relationship (P=0.014). Conclusions: Although ISS failed to show a statistically significant independent relationship with splenectomy, it may still play a supplementary role in traumatic splenic injury management.

To evaluate the influence of hepatic oxygen free radical systems on liver injury by topical p-phenylenediamine (PPD) application on rat skin, PPD (25 mg/16.5 $\textrm{cm}^2$) was topically applied to the abdominal region 5 times every other day and sacrificed. By PPD treatment, increasing rate of liver weight/body weight (%), serum activities of alanine aminotransferase and aspartate aminotransferase and decreasing rate of microsomal glucose-6-phosphatase activity were higher in the rats fed tungstate supplemented diet than those fed a standard diet. These findings indicate that group fed tungstate supplemented diet have more severe liver injury compared with group fed standard diet on topical PPD application. However, the activities of oxygen free radical generating enzymes such as xanthine oxidase (XO) and cytochrome P450 dependent aniline hydroxylase and those of oxygen free radical scavenging enzymes were not found to be different between these two animal groups. In the present study, a novel monitoring method to detect the generating of oxygen free radicals in liver extract was devised. Throughout this method, the oxidized PPD produced by oxygen free radicals was determined colorimetrically. The increasing rate of PPD oxidation by liver homogenate was higher in tungstate fed animals than in standard diet fed ones. Among the fractionations of liver extract, the mitochondrial and postmitochondrial fractions in the liver extract of tungstate fed animals led to a higher availability of PPD oxidation by PPD treatment compared with standard diet fed ones. In conclusion, these results suggest that an enhanced liver injury in tungstate fed animals treated with PPD may be due to oxygen free radicals produced in other systems except oxygen free radicals generating from cytosolic XO system. Especially, oxidative availability by PPD can be used for oxygen free radical detection in some tissue.

The case of a patient with a transfusion-related acute lung injury (TRALI) to whom extracorporeal membrane oxygenation (ECMO) had been applied is reported. A 55-year-old male injured with liver laceration (grade 3) without chest injury after car accident. He received lots of blood transfusion and underwent damage control abdominal surgery. In the immediate postoperative period, he suffered from severe hypoxia and respiratory acidosis despite of vigorous management such as 100% oxygen with mechanical ventilation, high PEEP and muscle relaxant. Finally, ECMO was applied to the patients as a last resort. Aggressive treatment with ECMO improved the oxygenation and reduced the acidosis. Unfortunately, the patient died of liver failure and infection. TRALI is a part of acute respiratory distress syndrome (ARDS). The use of ECMO for TRALI induced severe hypoxemia might be a useful option for providing time to allow the injured lung to recover.

Post-concussion syndrome (PCS) following mild traumatic brain injury (mTBI) is a major factor that contributes to the increased socioeconomic burden caused by TBI. Myelin loss has been implicated in the development of PCS following mTBI. Diffusion tensor imaging (DTI), a traditional imaging modality for the evaluation of axonal and myelin integrity in mTBI, has intrinsic limitations, including its lack of specificity and its time-consuming and labor-intensive post-processing analysis. More recently, various fast MR techniques based on multicomponent relaxometry (MCR), including QRAPMASTER, mcDESPOT, and MDME sequences, have been developed. These MCR-based sequences can provide myelin water fraction/myelin volume fraction, a quantitative parameter more specific to myelin, which might serve as a surrogate marker of myelin volume, in a clinically feasible time. In this review, we summarize the clinical application of the MCR-based fast MR techniques in mTBI patients.

Objective: The aim of this study was to determine the impact of the application of whole body vibration training (WBV) on the balance ability of patients with an American Spinal Injury Association (ASIA) type C or D spinal cord injury. Design: Randomized controlled trial. Methods: Twelve patients with spinal cord injury were enrolled in this study. The participants were randomized to an experimental group (n=6) or control group (n=6). The subjects in the experimental group received WBV exercise and the control group received the sham exercise without vibration. The vibrations were adjusted vertically to the patient at a 30 Hz frequency and 3 mm amplitude. The whole body vibration lasted for 16 minutes in total including 5-minutes warm-up and cool-down at the beginning and end of the program, respectively. The static sitting balance ability was assessed by measuring the postural sway while sitting on the force plate with the eyes opened or closed. Postural sway length was measured for 30 seconds with a self-selected comfortable position. Results: In the static balance test, the anterio-posterior, medio-lateral, and total postural sway length with the eyes open and closed was improved significantly before and after the intervention in the experimental group (p<0.05). The experimental group showed significantly more improvement than the control group (p<0.05). Conclusions: Our results demonstrated that WBV training has a positive effect on improving static sitting balance and enhanced control of postural sway in patients with an ASIA-C or D type spinal cord injury.

Purpose: The purpose of this study was to identify the effect of electroacupuncture(EA) and transcutaneous electric nerve stimulation(TENS) after sciatic nerve crush injury in rats. Methods: The EA for experimental group I (Exp I, n=15) and TENS for experimental group II (Exp II, n=15) was applied from post-injury day(PD) 1 to PD 14 after sciatic nerve injury using low frequency stimulator that gave electrical stimulation(15min/60Hz). In order observe the effect of EA and TENS, this study examined GAP-43 expression in rat lumbar spinal cord at the PD 1, PD 7 and PD 14. In addition, the stride length(SL) and toe out angle(TOA) were measured at the PD 7 and PD 4. Results; Exp I and Exp II had higher GAP-43 immunoreactivity than control group(PD 1, 7, 14). The SL of Exp I and Exp II were significantly higher than control group(PD 7, 14). The TOA of Exp I and Exp II were significantly lower than control group(PD 7, 14). Conclusion: EA and TENS application increased motor nerve recovery and expression of GAP-43 immunoreactivity after sciatic nerve crush injury. Therefore effect of TENS and EA had similar effect on nerve regeneration and functional recovery.

This convergence study was conducted to compare difference of risk behaviors and injury incidence between younger(under 65 years) and elderly(over 65 years). For this analysis we used law data of nation-wide community health survey data during August to October 2010. Data of drink-driving, seat belt use, injury incidence rate, type of injury, cause of injury were used for comparison. Seat belt use(85.16% vs 78.81%) was high but drink-driving(12.99% vs 13.24%) was low in elderly. Injury incidence was high especially in falls(1.07% vs 2.22%). In conclusion, elderly do less risk behaviors, but experienced much more injuries especially falls.

BACKGROUND: Liquid pig manure (LPM) has been used as an alternative for conventional fertilizers on some gramineous crops. However, its chemical properties varied widely depending on the degree of the digestion. A pot experiment was conducted to determine the responses of persimmon trees to immature (not well-digested) LPM application. METHODS AND RESULTS: Ten application levels of immature LPM, consisted of a total of 3 to 30 L in 3-L increment, were applied during summer to 5-year-old 'Fuyu' trees grown in 50-L pots. Increasing the LPM application rate caused defoliation, wilting, and chlorosis in leaves. When applied with the rate of 3 L during summer, the tree produced small fruits with low soluble solids and bore few flower buds the following season, indicating insufficient nutritional status. In trees applied with the LPM rates of 6~12 L, both fruit characteristics and above-ground growth of the trees appeared normal but some roots were injured. However, application of higher LPM rates than 27 L resulted in small size, poor coloration, or flesh softening of the fruits the current season. Furthermore, the high LPM rates caused severe cold injury in shoots during winter and weak shoot growth the following season. It was noted that the application of higher LPM rate than 9 L damaged the root, even though above-ground parts of the tree appeared to grow normally. CONCLUSION: The results indicated that an excessive immature LPM application could cause various injuries on leaves, fruits, and the roots in both the current and the following season.
