1.Protective effect of quercetin in lens
International Eye Science 2015;(1):49-51
?With the deepening study of quercetin, some studies show that quercetin can protect lens, with pharmacological activities such as antioxidation and anti-apoptosis and so on. And they can delay the occurring and developing of cataract. The development and utilization of the quercetin will be expected to be a new means of prevention and treatment of cataract. The article takes in the research progress of that quercetin on the lens with antioxidation, inhibiting aldose reductase and anti- apoptosis and its mechanisms.

Objective To explore the clinical characteristics of periampullary carcinoma in the prejaundice stage and improve early diagnosis rate and operative effects.Methods Clinical data of 27 cases with periampullary carcinoma in the prejaundice stage in our institute during the period of Jan 1998 to Dec 2005were analyzed retrospectively.Results The clinical symptom was mostly nonspecific, mainly included abdominal discomfort ( 92.6% ), abdominal pain ( 55.6% ), and irregular fever ( 29.6% ).The positive diagnosis rate with US, CT, MRCP, ERCP and EUS was 75.6%, 85.2%, 83.3%, 84.6%, and 88.9%,respectively, and they were helpful for early diagnosis.Among these 27 patients, 19 cases received regional pancreaticoduodenectomy, and 5 cases received pancreaticoduodenectomy in combination with vessel resection,3 cases received bile duct or gallbladder jejunal Roux-en-Y anastomosis, the overall resection rate was 88.9% with no operative mortality, and the post-operation complication rate was 7.4%.The 1,3, and 5 year survival rates were 100%, 70.8% and 41.7%, respectively.Conclusions The periampullary carcinoma in the prejaundice stage has its own clinical characteristics and abnormal image changes.If the diagnosis can be confirmed in the prejaundice stage, it is still an important method to improve the resection rate and prognosis.

Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.

Primary extracranial and extraspinal meningiomas are rare. Cases involving the orbit, skin, nasal cavity, paranasal sinuses, oral cavity and parotid gland have been reported. The histogenesis of primary extracranial meningioma is still nucertain, but it has been thought that this tumor originates from arachnoid cell rests in displaced during embryonal development. The authors observed a case of primary meningioma of the nasal cavity and paranasal sinuses occurring in a thirty-eight year old male patient in Feb. 1989. He suffered from bulging in the medio-superior portion of left orbit for 15 years, and left nasal obstruction and headache for 5 years, A head CT scan revealed numberous polypoid masses filling the left frontal sinus left ethmoidal sinus, left maxillary sinus and left nasal cavity. During the operation, a connection to the dura was not found. Microscopically, there were discrete lobules or netst of meningothelial cells, beneath the nasal mucosa. They showed an occasional whorling pattern and psammoma bodies. Therefore, this case was diagnosed as primary meningioma, meningotheliomatous type involving the left nasal cavity and paranasal sinuses.

This study was conducted to evaluate the blood lead levels in 141 pregnant women who were not occupationally exposed to lead and their umbilical cord, arid to identify some differences in blood lead levels by living area. ; The subjects-were all delivered at St. Benedict Hospital in Pusan and the blood lead levels were measured by graphite furance atomic absorption spectrophotometer. The summarized results were as follows. 1. The geometric mean lead levels in maternal and cord blood were 8.0+/-1.8microgram/dl, 5.0+/-0.6lmicrogram/dl respectively. 2. Lead levels in maternal (8.7+/-1.7microgram/dl) and cord blood(5.4+/-0.7microgram/dl) of industrial area(n=24) were higher than residential area(n= 124) which were 7.9+/-1.7microgram/dl and 5.0+/-0.6microgram/dl respectively (p<0.05). 3. Maternal blood lead concentration was significantly correlated to cord blood lead concentration (r=0.6090, p<0.001), but other variables (maternal age, paternal smoking, birth weight, etc) were not correlated.

Journal of the Korean Surgical Society 1999;56(4):570-578
BACKGROUND: For complicated appendicitis, in contrast to simple appendicitis, laparoscopic appendectomy (LA) is considered a relative or absolute contraindication because of the higher postoperative complication rate than that of open appendectomy (OA), especially, high incidence of intra-abdominal abscess. The purpose of this article is to assess the feasibility of LA for complicated appendicitis. METHODS: A retrospective review of 35 LA and 128 OA for the cases of gangrenous, perforated appendicitis, and periappendiceal abscess between May 1995 and June 1997 was performed. Patients were identified through the hospital pathology registry. We compared data from both groups with respect to operative times, postoperative pain, duration of ileus, length of hospital stay, and complication rate, with special attention to the incidence of intra-abdominal abscess. RESULTS: 1) The male:female ratio of LA (1:1.2) was significantly lower than that of OA (1:0.45) (p<0.05). There was no significant difference in the age distribution between both groups. 2) The mean operative time of LA (58.3 minutes) was significantly longer than that of OA (51.8 minutes) (p<0.05). 3) The mean number of injections of analgesics and the mean duration of ileus represented an advantage for LA (1.2 times and 1.8 days) than those of OA (1.6 times and 2.0 days). But these differences did not reach statistical significance. 4) The length of hospital stay of LA (6.5 days) was shorter than that of OA (7.8 dyas) (p<0.05). 5) Overall postoperative complication rate was lower in LA (11.4%) compared with OA (11.7) (p>0.05). But LA was associated with higher incidence of postoperative intra-abdominal abscess (3/35, 8.6%) than OA (3/128, 2.3%) (p=0.114). There was one serious intra-abdominal abscess in the LA, which required reoperation. The rest 2 cases in the LA and all 3 cases in the OA were treated conservatively. CONCLUSIONS: LA for complicated appendicitis could afford the merits of shorter hospital stay, reduced incidenceof wound infection, and comparable incidence of overall complication rate. To reduce the incidence of postoperative intra-abdominal abscess, copious irrigation and adequate drainage should be recommended.

PURPOSE: The purpose of our study was to assess the anomalous location and course of the superficial peroneal nerve (SPN), which were come across during exposure of distal fibula fracture. MATERIALS AND METHODS: We operated on 238 cases of ankle fractures, and examined the anomalous location and course of SPN around the distal part of the fibula. The study was performed prospectively. RESULTS: The mean length of surgical exposure was 9.8 cm. In 10 (4%) of 238 cases, the nerve was anomalous in its course, which was in parallel with the distal fibula and rapidly curved anteriorly at 3.5 cm proximal to the tip of the fibula. We found 3 cases of injury to the SPN; one was completely transected, the second was partially transected, and the third was stretched over the fracture site, at 2.5 cm, 5 cm, and 6 cm proximal to the tip of distal fibula, respectively. CONCLUSION: We emphasize the importance of a detailed neurologic examination, including sensory test for patients with ankle fractures, because of the variation in course of the SPN around the distal fibula.
