Small intestinal transit (SIT) has often been regarded as an index of pathophysiological state of postoperative ileus (PI) in rats. The reliability of SIT as an index of PI was examined in the present study. PI was induced via abdominal surgery (i.e., laparotomy with evisceration and manipulation) in rats. For one group of PI-induced rats, SIT of a charcoal test meal was measured. When necessary, the physical state (i.e., severity and site of distension) of the gastrointestinal (GI) tract in each rat was visually examined. For another group of PI-induced rats, abdominal X-ray radiographs were obtained after introducing the barium sulfate suspension. The abdomen was then opened and the physical state of the GI tract was visually examined. The SIT was decreased in most of the PI-induced rats, and the GI distension was observed, with substantial intersubject variations, in all of the PI-induced rats. However, no linear relationship was evident between the SIT and the severity of GI distension (e.g., at 20 h after PI induction). Instead, the severity and site of GI distension could be monitored by the X-ray radiology. Therefore, the use of SIT as an index of PI should be substantially limited.

Chicken carcass microflora were evaluated for aerobic microorganisms after defeathering, evisceration, washing, chilling, and sanitizing during a commercial chicken processing and storage at wholesale and retailsale levels. Sampling was at between December 1997, and March, 1998. Tap water washing and sanitizing with 25 ppm chlorine for 10 sec significantly (P<0.05) reduced aerobic plate counts (APC) and gram-negative bacterial counts (GNC) on chicken carcasses from a commercial chicken-processing plant. After 4 days at $2{\pm}2^{\circ}C$, APC and GNC on chicken carcasses in retailsale store rapidly increased compared to those in wholesale store (P<0.05). Chicken wings from retailsale store significantly (P<0.05) decreased generation time (GT) compared to other chicken carcasses.

Production of free radicals of superoxide anion in tissues by cadmium, activities of superoxide dismutase and catalase to protect tissue damages caused by the free radicals and ATPase that plays an important role in energy metabolism at cellular level were investigated. Experiments in vivo were conducted with liver, kidney and testicle tissue homogenates of rats adding $0.05{\sim}0.50mM$ cadmium chloride, and in vivo experiments administering single dose of 5 mg of cadmium/kg of body weight in 0.1% cadmium chloride solution intraperitoneally 48 hours prior to evisceration. Production of superoxide radicals in liver and testicle increased with addition of cadmium in vitro, but not in kidney. In vivo experiments, however, superoxide radicals slightly increased in liver and kidney but not in testicle. Superoxide dismutase (Cu, Zn-SOD and Mn-SOD), catalase and ATPase (total, $Mg^{++}-\;&\;Na^+,\;K^+-$) activity decreased in the presence of cadimium in dose dependent manner. Reduction of these enzyme activities varied not only with dosage of cadmium but also with type of tissue and between in vitro and in vivo experiment.

The records of 10 patients with traumatic diaphragmatic hernia seen from November 1977 through July 1987 were reviewed. All the patients had a transdiaphragmatic evisceration of abdominal contents into the thorax. We treated 7 male and 3 female patients ranging in age from 3 to 62 years. In 8 patients, diaphragmatic hernia followed blunt trauma and in 2 patients, stab wounds to the chest. The herniation occurred on the right side in 3 patients and on the left side in 7. All the patients sustained additional injuries: rib fractures [7 patients], additional limb, pelvic and vertebral fractures [6], closed head injury [2], lung laceration [1], liver laceration [1], renal contusion [1], ureteral rupture [1], and splenic rupture [1]. Organs herniated through the diaphragmatic rent included the omentum [6 patients], stomach [4], liver [4], colon [3], small intestine [1], and spleen [1]. For right-sided injuries, the liver was herniated in all 3 patients and the colon, in 1. in the initial or latent phase, dyspnea, diminished breath sounds, bowel sounds in the chest were noted in 4 patients, and in the obstructive phase, nausea, vomiting, and abdominal pain were found in all 3 patients. Two patients had a diagnostic chest radiograph with findings of bowel gas patterns, and an additional 8 had abnormal but nondiagnostic studies. Hemothorax, pleural effusion or abnormal diaphragmatic contour were common abnormal findings. Three patients were operated on during the initial or acute phase [immediately after injury], 4 patients were operated on during the latent or intermediate phase [3 to 210 days], and 3 patients were operated on during the obstructive phase [10 to 290 days]. Six patients underwent thoracotomy, 2 required thoracoabdominal incision, and 2 had combined thoracotomy and laparotomy. Primary suture was used to repair the diaphragmatic hernia in 9 cases. One patient required plastic repair by a Teflon felt. Empyema was the main complication in 2 patients. In 1 patient, the empyema was treated by closed thoracostomy and in 1, by decortication and open drainage. There were no deaths.

A 7-month-old intact male Maltese dog was presented with a 1.5-month history of glaucoma in the right eye (OD). Ophthalmic examinations revealed a corneal perforation with iris entrapment, corneal edema and neovascularization, and buphthalmos OD. Intraocular pressures were 33 mmHg OD and 19 mmHg in left eye (OS). The right eye was diagnosed with chronic glaucoma and corneal perforation with iris entrapment. Now that the eye was blind, implantation of intraocular silicone prosthesis (ISP) and conjunctival flap were elected to salvage the globe. The corneal perforation healed with the conjunctival pedicle flap and the cornea accommodated the ISP properly. A satisfactory cosmetic result was achieved without complications in the 15 months following the procedure. Therefore, this case report indicates the combined an ISP and a conjunctival flap would be an alternative for the treatment of glaucoma associated with corneal perforation in dogs.

Background: The nematode species belonging to genus Anisakis occur at their third larval stage in numerous marine teleost fish species worldwide and known to cause accidental human infection through the ingestion of raw or undercooked fish or squids. They may also draw the attention of consumers because of the visual impact of both alive and dead worms. Therefore, the information on their geographical distribution and clear species identification is important for epidemiological survey and further prevention of human infection. Results: For identification of anisakid nematodes species isolated from largehead hairtail (Trichiurus japonicus), polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of internal transcribed spacers of ribosomal DNA were conducted. Mitochondrial cytochrome c oxidase subunit 2 gene was also sequenced, and phylogenetic analysis was conducted. From the largehead hairtail (n = 9), 1259 nematodes were isolated in total. Most of the nematodes were found encapsulated throughout the viscera (56.2 %, 708/1259) or moving freely in the body cavity (41.5 %, 523/1259), and only 0.3 % (4/1259) was found in the muscles. By PCR-RFLP, three different nematode species were identified. Anisakis pegreffii was the most dominantly found (98.7 %, 1243/1259) from the largehead hairtail, occupying 98.7 % (699/708) of the nematodes in the mesenteries and 98.1 % (513/523) in the body cavity. Hybrid genotype (Anisakis simplex ${\times}$ A. pegreffii) occupied 0.5 %, and Hysterothylacium sp. occupied 0.2 % of the nematodes isolated in this study. Conclusions: The largehead hairtail may not significantly contribute accidental human infection of anisakid nematode third stage larvae because most of the nematodes were found from the viscera or body cavity, which are not consumed raw. But, a high prevalence of anisakid nematode larvae in the largehead hairtail is still in concern because they may raise food safety problems to consumers. Immediate evisceration or freezing of fish after catch will be necessary before consumption.

This study has been performed to measure the prevalence and microbial flora on chicken slaughtering as well as the processing process from the months of October to November. Whole-chicken rinsing technique was used in order to analyze the incidence of microorganisms on chicken carcass at the stage before chilling (after evisceration), after chilling and after cutting. The swab technique was used on processing the processed samples, such as working plates and cutting knives. Brine and cooling water from four cooling tubs were taken from each processing processes and were used as samples. Furthermore, the matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) for whole cell fingerprinting in combination with a dedicated bioinformatic software tool was used to identify the isolated microorganisms. Of the tested samples and processes, brine ($4.50{\pm}0.64$ Log CFU/mL) and chicken carcass before chilling ($4.15{\pm}0.46$ Log CFU/mL) showed the highest population of microorganisms; the predominant microbial flora of them were Moellerella wisconsensis (54.84%), a member of the Enterobacteriaceae family, and Escherichia coli (60.36%), respectively. However, the predominant microbial flora of cut carcass was changed to Staphylococcus aureus (27.32%), which is a kind of pathogenic microorganism that can cause a food-borne illness. Therefore, the slaughtering and processing procedure of chicken are needed to be controlled more hygienically.

Purpose: Despite the high incidence of abdominal stab injuries, the rate of nontherapeutic laparotomies and the predictors of therapeutic laparotomies have rarely been studied in low-income settings. Methods: This multicenter retrospective study involved three of the largest academic medical centers in central Ethiopia. All patients who sustained an anterior abdominal stab injury and underwent exploratory laparotomy, regardless of the intraoperative findings, were included over the 3-year course of the study. Results: Of the 117 patients who underwent exploratory laparotomy, 35 patients (29.9%) underwent nontherapeutic laparotomies. Three factors predicted therapeutic laparotomy: hollow viscus evisceration (adjusted odds ratio [AOR], 5.77; 95% confidence interval [CI], 1.16-28.64; P=0.032), localized and generalized peritonitis (AOR, 4.77; 95% CI, 1.90-11.93; P=0.001), and white blood cell count ≥11,500/mm³ (AOR, 2.77; 95% CI, 1.002-7.650; P=0.049). The overall positive predictive value of the therapeutic predictors was 80.2%, while the negative predictive value of all predictor-negative patients was 58.1%. The predictors would have prevented 51.4% of the nontherapeutic laparotomies. Conclusions: Close to one-third of the patients had a nontherapeutic laparotomy. The clinical predictors of therapeutic laparotomy were shown to have a high positive predictive value despite a lower negative predictive value. Further prospective studies that involve all patients who sustain anterior abdominal stab injuries are needed to potentially improve on the negative predictive value of the predictors suggested by our study.

Purpose: A classic approach to abdominal stab wounds has been a routine laparotomy for the purpose of diagnosis or treatment. However, management protocols for abdominal stab wounds are still contentious in most trauma centers. We examined the relationship between the character of the stab wound and the injured intraabdominal organs by retrospectively analyzing the medical records of patients with abdominal stab wounds admitted to Gil hospital, and the findings for our patients are then confronted with a review of the literature. We aimed to propose proper management protocols to approach abdominal stab wounds. Methods: The medical records of all 80 patients sustaining abdominal stab wounds, admitted at the Department of Surgery, Gil Hospital, Gachon Medical School, from January 2004 to December 2008 were retrospectively reviewed. All the abdominal stab wounds were collated based on the site and the character of the injury, investigations performed on admission, results of investigations, operations performed and findings at the time of the operation. Results: The most prevalent age group was patients in their forties and the average age of the patients was 41 years for both genders. The stab wounds were most commonly located at the periumbilical area (16.9%), followed by the epigastric area (15.6%), and 18.2% of the patients had multiple wounds. The most commonly eviscerated organ was the omentum (9 out of 16 cases); 61.7% of non-eviscerated patients underwent a therapeutic laparotomy while 81.3% of eviscerated patients underwent a therapeutic laparotomy. The small bowel was the most commonly injured organ (22.7%, 17 out of 75 injuries). The review revealed a relatively common diaphragmatic injury in abdominal stab wound patients (8 cases, 10.5%). The average hospital stay was 11 days. Conclusion: This review revealed commonly eviscerated and injured intraabdominal organs in abdominal stab wound patients and their relationship with a therapeutic laparotomy. Although the management is still controversial, the authors suggest indications for an immediate laparotomy and a protocol for managing abdominal stab wounds. Hemodynamic instability and peritoneal irritation signs are definite indicators for an immediate laparotomy, but the review revealed intraabdominal organ evisceration alone not to be a statistically significant factor. In addition, the authors suggest that abnormal CT findings can be valuable for making a decision on management of hemodynamically stable stab wound patients. Further study may clarify a role for a more selective approach to operative intervention and for a more extensive use of selective observation.

This study was carried out to evaluate the microbiological quality of poultry carcasses at different slaughtering process in large (>50,000 chicken/day) and small (<30,000 chicken/day) scale slaughtering houses. Whole bird rinse technique was used to analyze the incidence of microorganisms on poultry carcasses in each process of before visceration, after evisceration, after final wash, after main chilling and in cold room. In summer time, small scale slaughterhouse showed lower incidence of aerobic microorganisms (10$\^$4/ CFU/mL) than those of large scale slaughterhouse (10$\^$5/ CFU/mL) at the process of after main chilling and in cold room. But small scale slaughterhouse showed higher incidence of E. coli (10$^2$-10$^4$ CFU/mL) than those of large scale slaughterhouse (10$\^$-2/ CFU/mL) at each slaughtering process observed. During autumn and winter time, small scale slaughterhouse showed similar incidence of aerobic microorganisms as large scale slaughterhouse (10$\^$5/ CFU/mL after evisceration, 10$^4$ CFU/mL after main chilling and cold storage). Samples from carcasses during autumn and winter time in cold room showed no difference in E. coli counts (10$^2$ in autumn time and 10$^3$ CFU/mL in winter time) between large and small scale slaughterhouse. In spring time, small scale slaughterhouse showed lower incidence of aerobic microorganisms than those of large scale slaughterhouse at each slaughtering process observed except after main chilling. Small scale slaughterhouse showed higher incidence of aerobic microorganisms in final cooling water than large scale slaughterhouse during spring time.
