This study was carried out to investigate air pollution by total suspended particulate(T.S.P.), benzene soluble matter and benzo(a)pyrene in Seoul city. The sampling areas were divided into commercial(Kwang Hwa Moon), industrial(Ku Ro Dong) and residential area(Shin Chon). Sampling was undertaken by High Volume Air Sampler for four seasons from January 1977 to November 1977. The T.S.P. was extracted with Soxhlet apparatus by benzene and benzo(a)pyrene was separated by column chromatography and thin layer chromatography. The concentrations of benzo(a)pyrene were measured by means of fluorophotometer, and following results were obtained. 1. Arithmetic average concentration for 1-day averaging time of total suspended particulate were 275.6 microgram/m3 in Kwang Hwa moon, 325.9 microgram/m3 in Ku Ro Dong and 193.0 microgram/m3 in Shin Chon. 2. The seasonal variance of total suspended particulate at Ku Ro Dong and Shin Chon were 102.7 microgram/m3 99.6 microgram/m3 respectively and at Kwang Hwa Moon 39.9 microgram/m3. And the concentration of autumn is higher than of that spring at Ku Ro Dong and at Shin Chon, but at Kwang Hwa Moon, the seasonal variance is very little. 3. The concentrations of 50% frequency from geometric mean for 1-day averaging time were 264 microgram/m3 and 178 microgram/m3 at Kwang Hwa Moon, Ku Ro Dong and Shin Chon. And geometric standard deviation were 1.27, 1.38 and 1.41 respectively. 4. The concentrations of benzene soluble mater were 26.9 microgram/m3 Kwang Hwa Moon, 22.7 microgram/m3 at Ku Ro Dong and 15.5 microgram/m3 at Shin Chon, and the ratios to the T.S.P. were 9.8%(range 5.6-14.8%), 7.0%(range 2.4-14.4%) and 8.0%(range 5.5-22.1%) respectively. 5. The concentrations of benzo(a)pyrene were 8.5 microgram/m3 (range 0.8-29.9 microgram/m3 ) at Kwang Hwa Moon 10.9 microgram/m3 (range 1.1-52.0 microgram/m3 ) at Ku Ro Dong and 5.8 microgram/m3 (range 1.5-11.4 microgram/m3) at Shin Chon. 6. The results of this investigation were relatively high in compared with the recommended standards of suspended particulate in air of U.S. Environmental Protection Agency and observed levels of Benzo(a)-pyrene in U.S. city.

In order to investigate air pollution by heavy metals in Seoul city, the suspended particulates in the atmosphere were sampled with high volume air sampler in industrial area(Ku Ro Dong), commercial(Kwang Hwa Moon) and residential(Shin Chon Dong) from January to November, 1977. The sampled suspended particulates were digested and extracted from suspended particulates with the acidic solution by reflux-extraction technique, and were measured by atomic absorption spectrophotometry. And Mercury was measured by mercury analyzer applying the reducing sublimation technique. Among heavy metals analyzed, the iron was identified at th highest level in the suspended particulates and the chromium was the least. Through the surveyed area, the concentration of heavy metals of the industrial area was comparatively high among others and the commercial was the second. It was detected that lead was the most concentrated in the suspended particulate of the commercial area, that might be caused of the traffic emissions. The seasonal variations were analyzed and the correlations among heavy metals and total suspended particulate were also calculated. Especially, the iron was highly correlated with total suspended particulate in all the surveyed areas.

We must be assured that sympathetic ganglion block interrupts a vicious cycle of nerve impulses. Therefore, it prevents vasospasm and improves local circulation. The sympathetic ganglion block is effective in acute stage of herpes zoster and reduces the incidence of post-herpetic neuralgia. Herpes zoster is more often involved in an immunosuppressive imbalance. Three cases of herpes zoster were treated by repeated sympathetic ganglion block with 1% proved. Duration from onset of pain was 1 week, 1 month and 2 months, respectively. The block decreased the degree of pain markedly and dried up the vesicle in the early stage. Two of these three cases had suffering from diabetes melitus.

The pancreatic pseudocyst as a sequela of pancreatitis or pancreatic trauma can occur at any site in the abdomen. Its detection seems to be increasing with modern imaging tools such as abdominal ultrasound or abdominal CT scanning. But recently, we experienced a case of a pseudocyst due to a ruptured pancreatic pseudocyst which was misdiagnosed as a simple hepatic cyst by abdominal ultrasonography or abdominal CT scan. A 12-year-old male presented with recurrent epigastric pain during the past 4 years. On the abdominal ultrasound and abdominal CT scan, there was an 8x7.5 cm sized sharply defined thin-walled cyst in the left lobe of the liver. First, percutaneous (cather) drainage guided by ultrasonography was done. An exploratory laparotomy was performed because of signs of hemoperitoneum. A 8x7.5 cm sized cyst was found at the left subhepatic space, which communicated with another smaller cystic lesion in the pancreatic head. Microscopic finding of the cyst showed infiltration of inflammatory cells and granulation tissue without ephithelial lined cells which is compatible to a pseudocyst. So we report this case with a review of literatures.
