  • We describe here the mass death of predatory carp, Chanodichthys erythropterus, in Korea induced by plerocercoid larvae of Ligula intestinalis as a result of host manipulation. The carcasses of fish with ligulid larvae were first found in the river-edge areas of Chilgok-bo in Nakdong-gang (River), Korea at early February 2016. This ecological phenomena also occurred in the adjacent areas of 3 dams of Nakdong-gang, i.e., Gangjeong-bo, Dalseong-bo, and Hapcheon-Changnyeong-bo. Total 1,173 fish carcasses were collected from the 4 regions. To examine the cause of death, we captured 10 wondering carp in the river-edge areas of Hapcheon-Changnyeong-bo with a landing net. They were 24.0-28.5 cm in length and 147-257 g in weight, and had 2-11 plerocercoid larvae in the abdominal cavity. Their digestive organs were slender and empty, and reproductive organs were not observed at all. The plerocercoid larvae occupied almost all spaces of the abdominal cavity under the air bladders. The proportion of larvae per fish was 14.6-32.1% of body weight. The larvae were ivory-white, 21.5-63.0 cm long, and 6.0-13.8 g in weight. We suggest that the preference for the river-edge in infected fish during winter is a modified behavioral response by host manipulation of the tapeworm larvae. The life cycle of this tapeworm seems to be successfully continued as the infected fish can be easily eaten by avian definitive hosts.

  • Purpose: The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdominal cavity sites during gastric cancer surgery. Materials and Methods: We prospectively recruited 108 patients who were clinically diagnosed with locally advanced gastric cancer (higher than cT1 stage disease). Peritoneal washing fluids were collected from the pouch of Douglas and the subphrenic area. Patients were prospectively followed up for 2 years to determine the recurrence and survival rates. Results: Thirty-three patients dropped out of the study for various reasons, so 75 patients were included in the final analysis. Seven patients (9.3%) showed positive cytology findings, of whom, three showed peritoneal recurrence. Tumor size was the only factor associated with positive cytology findings (P=0.037). The accuracy and specificity of cytology for predicting peritoneal recurrence were 90.1% and 94.2%, respectively, whereas the sensitivity was 50.0%. The survival rate did not differ between patients with positive cytology findings and those with negative cytology findings (P=0.081). Conclusions: Peritoneal washing cytology using samples harvested from two different sites in the abdominal cavity was not able to predict peritoneal recurrence or survival in gastric cancer patients. Further studies will be required to determine whether peritoneal washing cytology during gastric cancer surgery is a meaningful procedure.

  • 과일 및 채소류의 곰팡이 억제제로 개발된 captafol은 인간 및 동물에서의 독성작용은 많이 보고된 바 있으나 이들의 독작용을 완화시키거나 치료할 수 있는 제제에 대한 연구는 별로 알려진 바 없다. captafol에 의한 혈액학 및 혈청 생화화적 변화에 따른 cysteine의 방어 작용을 확인할 목적으로 랫트에 5mg/kg 용량의 captafol을 1회 복강 투여하고 동시에 5, 58, 290 및 580mg/kg cysteine을 각각 투여하고 체중의 변화, 부검소견, 절대장기중량, 혈액학 및 혈청 생화학적 소견을 비교 분석 하였다. captafol 단독 투여군에서는 체중 및 간 장기중량 감소, 복강내 장기들의 섬유소에 의한 유착 및 복수 등이 현저하였으며 적혈구 수, hemoglobin 농도, 혈청 AST의 증가가 인정되었으며 또한 혈청 인지질 함량 감소가 확인되었다. 한편, cysteine 58mg/kg 이상의 용량군에서는 복강내 장기들의 유착 및 복수가 확인되지 않았으며 장기중량, 혈액학 및 혈청 생화학적 소견에서도 정상을 나타내었다. 이 연구 결과는 captafol의 중독증상에 대해 cysteine 및 sulfhydryl군을 가진 물질은 그 증세를 감소시키거나 완화시킬 수 있는 효과가 있음을 보여주고 있다.

  • The current experiment was carried out to investigate the analgesic effects of several herbal drugs in acetic acid - induced pain model. In a single drug group : after administration of herbal drugs(1g/kg or 3g/kg) orally for 30 minutes, 1% acetic acid $(250{\mu}l)$ was administered into abdominal cavity of mouse. And then the number of times of writhing response was measured for 30 minutes. In a combination drug group : after administration of herbal drugs (1g/kg and it's compound 2g/kg) orally for 30 minutes, 1% acetic acid $(250{\mu}l)$ was administered into abdominal cavity of mouse. And then the number of times of writhing response was measured for 30 minutes. The results were summarized as follows; 1. Water extracts of Akebiae caulis(木通) and Stephaniae tetrandrae radix(防己) decreased significantly the number of writhing response. 2. Methanol extracts of Achyranthis bidentatae radix(牛膝), Carthami flos(紅花), Akebiae caaulis(木通), Stephaniae tetrandrae radix(防己), Myrrha(沒藥), Corydalidis tuber(玄胡索) and Persicae semen(桃仁) decreased significantly the number of writhing response. 3. Water extracts of Achyranthis bidentatae radix(牛膝) plus Akebiae caulis(木通), Achyranthis bidentatae radix(牛膝) plus Stephaniae tetrandrae radix(防己) and Achyranthis bidentatae radix(牛膝) plus Ledebouriellae radix(防風) decreased the number of writhing response significantly. 4. Methanol extracts of Achyranthis bidentatae radix(牛膝) plus Myrrha(沒藥), Achyranthis bidentatae radix(牛膝) plus Stephaniae tetrandrae radlx(防己) and Achyranthis bidentatae radix(牛膝) plus Ledebouriellae radix(防風) decreased the number of writhing response significantly.

  • Paragonimiasis is a parasitic disease caused by Paragnonimus species. The primary site of infection is the lung, and extrapulmonary involvement is also reported. When infected with Paragonimus westermani, which is the dominant species in Korea, the central nervous system is frequently involved along with the liver, intestine, peritoneal cavity, retroperitoneum, and abdominal wall. Ectopic paragonimiasis raises diagnostic challenge since it is uncommon and may be confused with malignancy or other inflammatory diseases. Here, we report an ectopic paragonimiasis case initially presented with recurrent abdominal pain. The patient developed abdominal pain 3 times for the previous 3 years and the computed tomography (CT) of the abdomen revealed fluid collection with wall enhancement. Recurrent diverticulitis was initially suspected and part of the ascending colon was resected. However, the specimen showed intact colon wall without evidence of diverticulitis and multiple parasite eggs and granulomas were found instead. The size of about $70{\mu}m$, the presence of an operculum and relatively thick egg shell suggested eggs of Paragonimus species. With appropriate exposure history and a positive antibody test, the definitive diagnosis was made as peritoneal paragonimiasis.

  • Endometriosis is defined as the presence of functioning endometrial tissue outside the uterine cavity, and the standard treatment is extensive surgical excision. Cesarean scar endometriosis is a type of cutaneous endometriosis arising on or near a Cesarean section scar. A 44-year-old woman presented with a $9{\times}6$ cm sized dark-brown, stony-hard, irregular, lower abdominal mass of four years duration. The patient had a history of two Cesarean deliveries, 14 and 16 years ago. Suspecting endometriosis, we excised the tumor conservatively rather than extensively to prevent incisional hernia considering the benign nature of the tumor and the low possibility of recurrence because the patient's age was near menopause, along with simultaneous bilateral salpingo-oophorectomy that was performed in this case. On reconstruction, mini-abdominoplasty was adopted to avoid possible wound complications and cosmetic deformities. The patient was satisfied with the cosmetic results, and neither recurrence nor functional problems occurred during the 1-year follow-up period. Plastic surgeons should keep in mind the possibility of cutaneous endometriosis in an abdominal mass of a female of reproductive age with a previous history of pelvic or intra-abdominal surgery. An optimal result from oncological, functional, and cosmetic standpoints can be achieved with conservative excision followed by mini-abdominoplasty of extensive Cesarean scar endometriosis.

  • An intact male, 3-year old, Sapsari, weighing 29 kg with a history of respiratory distress, anorexia, abdominal distension, and depression for 1 day was referred. Radiographic findings included a C-shaped soft tissue mass in the mid-abdominal cavity and loss of serosal detail. Ultrasonographs showed splenomegaly with hypoechoic coarse parenchyma, loss of venous flow in the dilated splenic veins, and thrombi. Based on image findings, acute isolated splenic torsion was diagnosed. Splenectomy and prophylactic gastropexy was performed. Another case was a spayed female, 8-year old, Shih-tzu, weighing 3.7 kg with a history of intermittent abdominal pain and a palpable abdominal mass for 1 year. Radiographic findings showed splenomegaly characterized by a soft tissue round mass. Ultrasonographs revealed displaced splenic hilum and absence of venous flow in the dilated splenic vein. Chronic isolated splenic torsion was diagnosed and also splenectomy and gastropexy was performed. Two dogs were recovered normally after surgery without any complications. Acute form of isolated splenic torsion showed acute systemic clinical signs, severe C-shaped splenomegaly on radiographs, and loss of all of splenic venous flow, perivenous hyperechoic triangle sign, and thrombi on ultrasonographs. Chronic form of isolated splenic torsion showed chronic obscure clinical signs, moderate splenomegaly on radiographs, and partial loss of splenic venous flow on ultrasonographs.
