위대한 ( Dae Han Wi ) 대한임상독성학회 2012 대한임상독성학회지 Vol.10 No.2

Alocasia was originally distributed throughout subtropical and tropical areas. Recently, in Korea, it has been used in air cleaners and in control of humidity. Despite easy access in Korea, there are few reports on Alocasia toxicity. We report on two cases of Alocasia intoxication. One patient was a 16-month-old male, who was admitted with a complaint of irritability after biting leaves of Alocasia. Four hours later, he was discharged without any symptoms. Another patient, a 52-year-old female, complained of oral pain, numbness on the perioral area, dysphonia, swallowing difficulty, and chest and abdominal pain after eating root stuck of alocasia odora. She underwent gastrointestinal fibroscopy (GIF) due to lasting chest and abdominal pain. Finding on GIF showed erythema and swelling in the aryepiglottic fold and larynx. Her symptoms lasted 13 days; she was then discharged without any complications or sequelae.

Lysholm`s knee score는 평균 88.2±4.3점이었다. 결론: 감입형 경골 고평부 골절에서 신선 동결 동종 해면골 이식은 골유합과 기능 회복에 도움이 되며, 정복된 관절면의 유지를 위해 좋은 구조적 보강물이라고 생각된다. Purpose: To assess the behaviour of fresh frozen cancellous allograft used for supporting the reconstructed articular surface in impacted tibial plateau fractures. Materials and Methods: Between May 2004 and May 2008, 13 cases of impacted tibial plateau fracture were evaluated retrospectively. All fractures were treated with open reduction-internal fixation after restoration of the tibial plateau surface and insertion of fresh frozen cancellous allograft chips for subchondral support. Mean age was 46.6 (31∼65) years. Average follow-up period was 36 (13∼58) months. The radiological and clinical result for every patient was assessed according to the modified Rasmussen`s system and Lysholm`s knee score. Results: According to last follow-up weight bearing A-P X-ray, the fresh frozen cancellous allograft incorporated soundly in all cases and no complications such as joint depression, fracture reduction loss, angular deformity, and malunion were found. The mean time to complete bone union was postoperative 10±0.7 weeks. The mean range of motion was 135 (115∼145) degrees. The mean Rasmussen`s radiological score at last follow up was 15.3 (10 cases: excellent, 3 cases: good). The mean Lysholm`s knee score at last follow up was 88.2±4.3. Conclusion: We concluded that fresh frozen cancellous allograft in impacted tibial plateau fractures showed good results in terms of bone union and functional improvement and was considered to be a good structural supporter.

Background : It has been well known that cFos protein, one of the immediate-early gene proteins, was a cellular marker to characterize physiological or anatomical property of neural networks in mammalian brain. The purpose of this study was to evaluate quantitative change of cFos protein expression in rat brain nuclei concerned with regulation of blood pressure according to severity of hypotension and compare the spatial pattern of cFos between hemorrhagic hypotension and non-hemorrhagic hypotension elicited by vasodilatation. Methods : The mean blood pressure (MBP) in the femoral artery was recorded by using pressure transducer and polygraph. Nitroprusside was injected into the femoral vein with constant flow rate by means of osmotic pump in which the dosage was 5 ㎍ per kg a minute. Immunohistochemical staining was performed by using conventional ABC method to visualize cFos-like immunoreactive (cFLI) neurons in many brain nuclei and FLI cells were counted by image analyzer. Results : Mild hemorrhage group with MBP of 70-80 mmHg showed significant increase of cFLI expression in the paraventricular nuclei and supraoptic nuclei. In contrast, severe hemorrhage group with MBP of 50 mmHg increased significantly cFLI expression in the rostral ventrolateral medulla, periventricular thalamic nucleus, central gray matter, medial vestibular nuclei as well as the nuclei seen in mild hemorrhage group. Nitroprusside induced hypotension exhibited a similar spatial pattern of cFLI expression to severe hemorrhage group. Conclusion : These results suggest that severe reduction of blood pressure induces expression of cFLI neurons in the neural network systems that control vital organs.

Abdominal tuberculosis is described in two forms; tuberculous peritonitis and gastrointestinal tuberculosis. Abdominal tuberculosis is usually insidious onset with diverse symptoms and signs. The diagnosis is difficult, especially in areas where the disease is less common, as many patients do not have evidence of pulmonary tuberculosis or a positive skin test. Physicians should obtain a thorough history focusing on risk behaviors for tuberculosis. Delayed diagnosis is common, resulting in high mortality. In general, the same regimens are used to treat pulmonary and abdominal tuberculosis. Most intra-abdominal and other types of fluid collections are now successfully drained percutaneously under image guidance. The utility of percutaneous drainage(PCD) of tuberculous abscesses is less well established. A 43-years-old man, who had been diagnosed as pulmonary tuberculosis about 9 years ago, suffered from peritoneal abscess because of delayed diagnosis. The diagnosis of tuberculosis was confirmed by the PCR tests for the detection of Mycobacterium tuberculosis in the aspirates from the abscess. Drainage was done by catheter under ultrasound guidance and there were no procedural complications. The abscess was successfully and completely evacuated. We present our experience with a case of tuberculous peritoneal abscess which were successfully treated by PCD and antituberculous medication.
