To observe whether the measurement of enzyme activity has any critical role in assesment of diagnostic value, beta-glucuronidase and lactic dehydrogenase activities in neoplastic tissue of stomach were compared with those in the stomach at the stomach mucosa at the antrum and body which was uninvolved by tumor. And then activities of those enzymes were also compared with differentiated and undifferentiated carcinomas. The stomach tested were obtained by gastrectomy in Pusan National University Hospital during the months from March to June in 1983. The results were summarized as follows: 1) beta-glucuronidase activity in the neoplastic tissue of stomach was higher than that in the antral and body mucosa, and this enzyme activity in the antral mucosa with intestinal metaplasia was higher than that in the body mucosa of stomach. 2) Lactic dehydrogenase activity in the neoplastic tissue of stomach was similar to that in the antral mucosa with intestinal metaplasia, and was higher than that in the body mucosa of stomach. 3) Acitivities of both enzymes in the neoplastic tissue of differentiated carcinoma were slightly higher than that of undifferentiated one, but did not found statistically significant difference. 4) In the neoplastic tissue of the stomach there was no significant correlation between beta-glucuronidase and latic dehydrogenase activities. Above results support that the measurement of gastric juice enzymes is useful in the diagnosis of stomach carcinoma and may be of value in the identification of high-risk groups.

Ganglia in soft tissue are common and usually occur in close relations with joints, tendon sheaths, or tendons. However, intra-osseous ganglia are very rare. We report a case of intra-osseous ganglion arising from the right sided proximal humerus in a 33 year-old woman. It was multiple cysts surrounded by thin rims of sclerotic bone in the subchondral epiphysis without other features of degenerative joint disease or destruction of adjacent soft tissue.

We report a case of extraskeletal osteosarcoma in view of rarity, and a brief review of the literature related to this type of tumor is presented. The patient was a 31-year-old Korean woman, who had noticed a bean-sized hard mass in the right thigh progressively enlarged to become egg-size during about 7 months, followed by pain and tenderness. There was neither recognizable previous lesion nor causable agent about the mass on history taking. Physical examination revealed another palpable mass on the inguinal area. The right thigh and inguinal masses were simply excised and histologically confirmed to be an extraskeletal osteosarcoma and metastatic one, respectively.

This sutdy was performed to find out a LD isoenzyme pattern in neoplastic tissue of gastric carcinoma and in gastric mucosa with intestinal metaplasia, which has been known as premalignant lesion. The specimens used in this study were 18 stomachs with caarcinoma and 8 stomachs with peptic ulcer as control, and wer obtained by subtotal or total gastrectomy at Pusan National University Hsopital from Oct. 1987 to Sept. 1988. Total LD activity and its isoenzymes in body and antral mucosae and neoplastic tissue of stomach were assayed, and analysed statistically from several points of view. The results obtained were summarized as follows: 1) There was no significant difference in total LD activity between univolved body and antral mucosae of stomach with carcinoma, and between mucosa of stomach with peptic ulcer and univolved mucosa of stomach with carcinoma. 2) Total LD activity in the neoplastic tissue of gastric carcinoma was significantly higher than those of univolved body and antral mucosae of stomach with carcinoam or that of stomach with peptic ulcer, but no significant difference was observed among histological types of gastric carcinoma. 3) The uninvolved body mucosa of stomach with carcinoma or peptic ulcer showed a pattern of LD1 predominance and increas of H to M ratio, while the antral mucosa of stomach with carcinoma or peptic ulcer showed a pattern of LD3 predominance and decrease of H to M ratio. 4) The LD4 and LD5 fractions in antral mucosa with moderate to severe intestinal metaplasia were slightly increased than those of antral mucosa with nil to mild intestinal metaplasia, but did not show statistically significant difference. 5) Marked increase of LD5 fraction was found in neoplastic tissue of gastric carcinoma, and thus ratio of H to M subunit in neoplastic tissue was significantly lower, as compared with body or antral univolved mucosa of stomach. In conclusion, the neoplastic tissue of gastric carcinoma and gastric mucosa with intestinal metaplasia show substantially predominant "M" subunit as well as increased total LD activity.

This study was performed for the purpose of evaluation of plasma PGE2, levels in patients with gastric carcinomas. To carry out this study twenty-one gastrectomy patients with gastric carcinoma were selected. Serial plasma PGE2 levels were measured before and after operation by radioimmunoassay. Plasma PGE2 was also measured in five normal healthy volunteers or of patients with gastric ulcer. The conclusion drawn therefrom were as followed: 1) In normal healthy volunteers, plasma PGE2 level was 50.2+/-16.5 pg/ml which ws higher than that of parients with gastric ulcer, 20.7+/-15.4 pg/ml, (p<0.001). 2) In patients with diffuse type of gastric carcinoma, preoperative and postoperative plasma PGE2 levels were 25.7+/-12.1 pg/ml, and 23.1+/-8.7 pg/ml, rewpectively. In parients with intestinal type of gastric carcinoma, preoperative and postoperastive plasma PGE2 levels were 26.2+/-8.9 pg/ml and 24.1+/-11.2 pg/ml, respectively. In both types of gastric carcinoma, plasma PGE2 levels were lower than that of normal healthy volunteers and there was no significant difference compaired with the levels in patients with gastric ulcer. 3) In diffuse and intestinal types of gastric carcinoma, postoperative PGE2 levels were lower that those of preoperative state but it was not significant. 4) In early and advanced gastric carcinoma, preoperative PGE2 levels were 29.0+/-11.7 pg/ml and 24.8+/-9.9 pg/ml, respectively. There was no significant difference by the depth of invasion. From the result as mentioned above, it is concluded that plasma PGE2 levels of patients with gastric carcinoma and it is presumable that there is a factor decreasing plasma PGE2 levels in patients with gastric carcinoma or ulcer.

Health services on industrial noisy environment have been provided only for noise-induced hearing loss management until now. But gradually, modern diseases and death have come to be related to stress and mental health deeply, therefore noise-induced mental disorder, like a stress became very important. In this point, the purpose of this study was to analyze the relationship between noise exposure level in worksite and workers' stress symptoms. This study included a survey of 786 manual workers selected from 89 worksites in 21 factories in Puchon. The results were as follows: 1. For demographic characteristics, most of the workers were males(80.8%), the 20~29 years old were 34.5% and those who graduated from high school were 65.3%. The workers whose monthly income ranged from 500,000 to 800,000 won were 37.5% and who have a religion were 47.9%. 2. For occupational characteristics, workers who had worked 1~5 years in the factories were 33.0%. Those who felt much for them workload were 43.9% and who worked more than 8 hours a day were 73.9 %. Those who were dissatisfied with their job and pay were 31.9% and 50.6%. The workers who responded ventilation condition of their worksites were bad were 51.9% and the dissatisfied with working environment of their wofksites were 45.9%. 3. Workers who were suffering from tinnitus were 53.3% and those who perceived hearing loss were 50.l%. Persons who reported they always wore earplugs at work were 35.4%. Those who felt earplugs bigger than their ears were 30.6% and those who experienced eardiseases caused by earplugs were 25.6%. 4. For the noise exposure level in worksite, workers who were exposed to 80-90dB were 30.3%, 90-100dB were 26.4% and 50~70dB were 19.2%. 5. workers' stress symptoms were significantly related to marital status and their monthly income p< 0.05). Workers who were single and had lower monthly income showed higher PSl (Psychiatric symptom Index) scores than those who were married and had higher monthly income. Higher PSl scores were also significantly related to l~2 days night-work per week, much for them workload, dissatisfaction with their job, and bad relationship with their bosses and coworkers. 6. Higher PSl scores were significantly related to severe tinnitus and perceived hearing loss p<0.001). Workers who felt the earplugs they use did not fit their ears showed significantly higher PSl scores(p<0.01). Workers who reported that they did not feel they need earplugs showed significantly higher PSl scores(p<0.05). Increased experience of eardisease caused by earplugs that did not fit were also significantly related to higher PSl scores(p<0.001). 7. The higher noise exposure level in worksite from 80dB was, the more severe stress symptoms including PSl subparts were reported; Anxiety, Anger, Depression, and cognitive disorder(p<0.001). 8. According to the results of stepwise multiple regression analysis, factors affecting workers' PSl scores were perceived hearing loss(R2=0.160), noise exposure level jn worksite(R2=0.110), relationship with coworkers, amount of workload, monthly income and relationship with bosses orderly and the total R2 of this 6 factors was 0.371. 9. The most significant factors that have impact on manual workers' stress symptoms were perceived hearing loss and noise exposure level in worksite, especially noise exposure level in the worksite was the most affective factor on the depression symptom.

We describe a case of traumatic aortic dissection associated with cardiac compression in a patient with anaphylactic cardiac arrest who underwent cardiopulmonary resuscitation (CPR). A 54-year-old man who was scheduled to undergo surgery for gastric cancer went into cardiac arrest caused by an anaphylactic reaction to prophylactic antibiotics in the operating room. Veno-arterial extracorporeal membrane oxygenation (ECMO) was performed. CPR, including chest compressions, was performed for 35 minutes, and the patient was transferred to the intensive care unit (ICU) after spontaneous circulation returned. The patient received ECMO for 9 hours until confirmation of normal cardiac function on transthoracic echocardiography. Twenty days after cardiac arrest, an aortic dissection and fractures in the left fourth and fifth ribs due to chest compression were detected by abdominal computed tomography. The DeBakey type III aortic dissection extended from the distal arch of the thoracic aorta to the proximal level of the renal artery, involving the celiac trunk. It was considered an uncomplicated type B aortic dissection with no sign of malperfusion of the major vessels. This case demonstrates the potential traumatic injuries that can occur after CPR and encourages proper management of mechanical complications in cardiac arrest survivors.
