A clinical analysis was performed on 383 cases of chest injurjes experienced at Department of Thoracic Surgery, Seoul National University Hospital during 21 year period from 1957 to 1977. Of 383 patients of chest injuries, 209 cases were result from nonpenetrating injuries whereas 175 were from penetrating injuries, and there were 258 cases of hemothorax or/and pneumothorax, 162 of rib fracture, 33 of foreign body, 26 of clavicle fracture, 26 of lung contusion, 17 of diaphragmatic laceration, 14 of hemopericardium, 14 of flail chest and others. Stab wound was the most common in penetrating injuries and followed by gunshot and shell fragments. The majority of nonpenetrating chest injury patients were traffic accident victims. and fails accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 16 and 50 years, and 321 patients were male comparing to 62 of female. In blunt chest injuries the patients with five or more rib fractures had a 85 per cent incidence-of intrathoracic injury and 19 per cent had an intraabdominal organ damage, whereas those with four or less rib fractures had a 69 per cent and a 6 per cent incidence respectively. The principal associated injuries were cerebral contusion on 19 cases, renal contusion on 10, liver laceration on 7, peripheral vessel laceration on 5, spleen laceration on 3 and extremity fracture on 18 patients. The principles of therapy for early complications of chest trauma were rapid reexpansion of the lungs by thoracentesis [46 cases] and closed thoracotomy [125 cases] but open thoracotomy .had to be done on 90 cases [23-5%] because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic laceration and bronchial rupture. The over all mortality was 2.87 per cent [11 among 383 cases], 8 cases were from penetrating injuries and 3 from nonpenetrating injuries.
Objectives : in recent years, there have been some case reports about liver injuries suspected to be caused by Heshouwu, the root of Polygonum multiflorum. So, I investigated liver function tests of patients who had taken Heshouwu, to know whether Heshouwu was hepatotoxic. Methods : I surveyed whether Heshouwu caused liver injury in patients, who had been admitted and taken Heshouwu at Dongguk University International Hospital, from May 2005 to July 2008. I looked over all the liver function tests of those patients, done during medication and 30 days after. Results : Among 1,449 inpatients, there were 124 patients who had taken Heshouwu. Among those 124 patients, 14 cases whose liver function tests were abnormal before medication were excluded. 69 cases who did not take liver function test 30 days after were also excluded. As a result, 41 patients were enrolled, and their mean dosage was 14.04(8-24) g/day, and the mean medication period was 13.8 (1-89) days. During and after medication, there were no abnormal liver function test results at all, in the enrolled cases. Conclusions : Roughly speaking, according to the above results, it seems that taking Heshouwu for about two weeks as per the commonly taken dosage did not cause hepatotoxicity, though we needs more laboratory and clinical research to reach a more definitive conclusion.
Background: The first 3 ribs are anatomically well-protected, shielded by the large thoracic muscles, the shoulder girdle, and the arm. A significant force is required to fracture these ribs; thus, such fractures suggest a high-energy trauma and are associated with injuries to vital organs of the thorax, such as the aorta, the heart, the lungs and the great vessels. Methods: A retrospective analysis was conducted over a 10-year period at a single hospital. The study assessed patients with fractures of the second rib, including their concurrent injuries and the overall severity of their trauma. Results: Among the 76 patients included in the study, the average age was 47.35 years, 81.5% were men, and 19.5% were women. Thirteen patients (17.1%) survived their injuries. The most common causes of injury were road traffic accidents (63%) and pedestrian injuries (22%). The patients who did not survive sustained injuries to an average of 5 additional organs, while survivors had injuries to an average of 2.07 additional organs. Left rib fractures were the most frequently observed (46%). The most serious concurrent injuries reported were to the aorta (5.26%), heart (10.52%), lung (52.36%), head (57.89%), liver (30.2%), spleen (26.31%), and kidney (17.1%). Conclusion: As indicators of serious injury to vital endothoracic organs, isolated fractures of the second rib should be considered equal to first rib fractures in clinical importance.
Objectives : The purpose of this study was to evaluate the hepatoprotective effect of Hovenia dulcis extract on acute and chronic liver injuries induced by alcohol and $CCl_4$ in mice and rats. Methods : In acute alcohol-induced liver injury, mice were administered Hovenia dulcis extracts (60 and 200 mg/kg) orally before and after alcohol administration. In chronic alcohol-induced liver injury, mice were administered alcohol containing liquid diet for 4 weeks. The mice were administered H. dulcis extracts (60 and 200 mg/kg) mixed with the liquid diet. In acute $CCl_4$-induced liver injury, rats received a single dose of $CCl_4$ (2 mL/kg in olive oil, intraperitoneally). Rats were administered H. dulcis extracts (30, 100 and 300 mg/kg) before and after $CCl_4$ administrations. After the ends of the administrations, the serum levels of AST and ALT were measured using chemical analyzer, and ${\gamma}$-GTP levels were measured using spectrophotometer. Results : In acute alcohol-induced liver injury, H. dulcis extracts treated group showed significant reduction in ALT levels compared to those of control group. In chronic alcohol-induced liver injury, it inhibited weight-loss compared to normal group and showed significant reduction in AST, ALT and ${\gamma}$-GTP levels compared to control group. In acute $CCl_4$-induced liver injury, it also showed significant reduction in AST, ALT levels compared to control group. Conclusions : The results show that H. dulcis extract has hepatoprotective effect in acute and chronic alcohol-induced liver injury and acute $CCl_4$-induced liver injury. These findings suggest that H. dulcis could be a potent hepatoprotective agent.
22 Cases of traumatic diaphragmatic injuries treated at the Department of Thoracic and Cardiovascular Surgery in Chon-Buk National University Hospital from Jan. 1979 to Oct. 1988 were reviewed in this study. Of the 22 cases, 18 were male and 3 were female, a ratio of 4.5:1. This ratio revealed high incidence in male patient. The age distribution ranged from 2 to 60 years and mean age was 31 years. The modes of injury were as follows: 11 stab wound, 5 traffic accident, 2 fall down, 2 fighting injury, 1 compression wound by sand bag, and 1 slip down injury. Useful diagnostic tools were chest X-ray with or without radiopaque dye swallowing, which was the most commonly diagnostic, UGI series, and thoracoscope. Operations were performed in 22 cases, and 18 cases were through thoracotomy. The herniated organs through the ruptured diaphragm were stomach, omentum, liver, spleen, colon, and small bowel. There were associated injuries, and the most commonly associated was rib fracture. There was no postoperative death.

Penetrating gallbladder injuries are uncommon in the pediatric population. The treatment varies according to the severity of the injury and the patient's hemodynamics. We present the case of an 11-year-old male with an accidental pellet gunshot wound to the right upper abdomen that resulted in a grade III liver laceration and damage to the anterior gallbladder wall. The patient underwent laparoscopic cholecystectomy with drain placement. Postoperative radiography of the surgical specimen confirmed the presence of the pellet in the gallbladder. The patient recovered uneventfully and was discharged home on postoperative day 3. Laparoscopic cholecystectomy is a feasible treatment option for penetrating gallbladder injuries in hemodynamically stable patients.
To investigate an effect of ethanol pretreatment on the bromobenzene metabolism, the brornobenzene (400 mg/kg body wt. i. p.) was given 3 times at intervals of one day to the male rats orally pretreated with 5% ethanol throughout 2 months. In the ethanol pretreated rats, liver injuries were not demonstrated on the basis of the liver weight per body weight, serum levels of alanine aminotransferase (ALT) activity and histopathologic findings. By the bromobenzene treatment, ethanol pretreated rats showed the more decreased levels of serum ALT and liver weight/body weight(%), and decreased degree of liver damage on histopathological observation than the control group. The ethanol pretreated rats showed the more increased activities of hepatic aniline hydroxylase, glutathione Stransf erase (GST) and the more decreased contents of glutathione than the control. Concomitantly the ethanol pretreated rats showed the more decreased contents of hepatic glutathione and increased activities of GST by the bromobenzene treatment. Above results indicate that ethanol pretreatment enhance the metabolizing ability of bromobenzene in rats.
Purpose: Acute liver failure after massive partial hepatectomy is critical condition with high mortality. To prevent postoperative liver failure from being induced by a massive partial hepatectomy, many doctors do a minimal resection on the single lobe of the liver that might cause postoperative bleeding from the remaining ruptured parenchyma. The objective of this study was to assess clinical experience with postoperative hepatic arterial embolization to control bleeding from the remaining ruptured liver during the postoperative period. Methods: This retrospective 4-year study was conducted from May 2002 to April 2006 and included consecutive patients who had sustained massive hepatic injuries and who had undergone a laparotomy, followed by postoperative hepatic arterial angiographic embolization to control bleeding. Data on the injury characteristics, the operative treatment and embolization, and the amount of transfused packed red cells (PRBC) were gathered and analyzed. In addition, data on the overall complications and survival rate were collected and analyzed. Results: Every case showed severe liver injury, higher liver injury scaling grade IV. Only ten cases involved a ruptured bilateral liver lobe. A lobectomy was done in 6 cases, a left lobectomy was done in 3 cases, and a primary suture closure of the liver was done in 2 cases. Suture closure was also done on the remaining ruptured liver parenchyma in cases of lobectomies. The postoperative hepatic arterial embolizations were done by using the super-selection technique. There were some cases of arterio-venous malformations and anomalous vessel branches. The average amount of transfused PRBC during 24 hours after embolization was $2.36{\pm}1.75$, which statistically significantly lower than that before embolization. Among the 11 cases, 9 patients survived, and 2 died. There was no specific complications induced by the embolization. Conclusion: In cases of postoperative bleeding in severe hepatic injury, if there is still a large amount of bleeding, postoperative hepatic arterial embolization might be a good therapeutic option.
The management of twenty-two children with blunt abdominal trauma was analyzed. Nineteen cases had intraabdominal injuries; involving the spleen in 7 cases, the liver in 5, the pancreas in one and the bladder in one. There were five case multiple intraabdominal organ injuries. Seventeen out of 19 patients were treated non-operatively, but one was operated upon later because of delayed bleeding. Thirteen patients required transfusion in the non operated group, the mean values of the Pediatric Trauma Score (PTS) was 11.3. The mean lowest hemoglobulin(LHb) was 9.1 g/dL. The mean value of three cases with extraabdominal injuries were 9.0 and 8.3 g/dL respectively. The average amount of transfusion was 17.3 ml/kg. In the operated group, 2 cases were transfused an average of 139.8 ml/kg and their mean PTS was 5 and LHb was 6.6 g/dL. In one out of 16 non-operated cases, intrahepatic hematoma developed and but resolved conservatively. However, two out of 3 operated cases suffer complications such as an intubation granuloma and an intraabdominal abscess with wound dehescence. In conclusion, non-operative management in child with blunt abdominal trauma was safe in Grade I and II solid organ injuries. The decision for operation should be based on the hemodynamic stability after initial resuscitation including transfusion.

Liver fibrosis is part of the wound healing process to help the liver recover from the injuries caused by various liver-damaging insults. However, liver fibrosis often progresses to life-threatening cirrhosis and hepatocellular carcinoma. To overcome the limitations of current in vivo liver fibrosis models for studying the pathophysiology of liver fibrosis and establishing effective treatment strategies, we developed a new mouse model of liver fibrosis using polyhexamethylene guanidine phosphate (PHMG-p), a humidifier sterilizer known to induce lung fibrosis in humans. Male C57/BL6 mice were intraperitoneally injected with PHMG-p (0.03% and 0.1%) twice a week for 5 weeks. Subsequently, liver tissues were examined histologically and RNA-sequencing was performed to evaluate the expression of key genes and pathways affected by PHMG-p. PHMG-p injection resulted in body weight loss of ~15% and worsening of physical condition. Necropsy revealed diffuse fibrotic lesions in the liver with no effect on the lungs. Histology, collagen staining, immunohistochemistry for smooth muscle actin and collagen, and polymerase chain reaction analysis of fibrotic genes revealed that PHMG-p induced liver fibrosis in the peri-central, peri-portal, and capsule regions. RNA-sequencing revealed that PHMG-p affected several pathways associated with human liver fibrosis, especially with upregulation of lumican and IRAK3, and downregulation of GSTp1 and GSTp2, which are closely involved in liver fibrosis pathogenesis. Collectively we demonstrated that the PHMG-p-induced liver fibrosis model can be employed to study human liver fibrosis.
