N/A To evaluate the diagnostic accuracy of serum complement level as an early diagnostic tool of hepatocellular carcinoma in cirrhotic patient, we examined 22 cases of liver cirrhosis and 16 cases of liver cirrhosie with hepatocellular carcinama. The results are as follows; 1) In liver cirrhosis with hepatocellular carcinoma, serum complement level was higher than liver cirrhosis. 2) When the serum cornplement levels, C3; 61 mg/dl and C4; 41 mg/dl, were indicated as the cutoff value in differential diagnosis of liver cirrhosis and hepatocellular carcinoma with liver cirrhosis, the poeitive predictive value, negative predictive value, and accuracy were 90%, 75%, and 79%, respectively. 3) When in serum AFP level, the cutoff value was disclosed as 400 ng/ml, the positive predictive value, negative predictive value, and accuracy of serum alpha fetoprotein were 100%, 31%, and 74% respectively, 4) Considering combination of above described data of serum C3, C4 and AFP, the positive predietive value, negative predictive value, accuracy were 92%, 81%, 84% respectively. Based on these data, serum complement level may be used as a valuable tumor marker in the die oais of hepatocellular carcinoma in cirrhotic patient eapecially when it is considered together with rum alpha fetoprotein level.

The new South Korean administration initiated the ‘Vision 3000: Denuclearization and Openness’ plan which stipulates that if North Korea undertakes verifiable and complete dismantlement of its nuclear programs and chooses the path to openness and reform, South Korea, along with the international community, will help the North improve its economy, education, finance, and welfare systems and raise its per capita GDP up to the $3000 level within 10 years. So, it is imperative that North Korea should give up its nuclear program before it gets any help from South Korea and international communities. It means that the future of Korean peninsula and inter-Korean cooperation lies in the progress of North Korean nuclear problems. The central government, which is hardly free from international variables and constraints, should consider strategic and security issues when it pursues any business with North Korea. However, the local government, relatively less constrained by the political and security calculations, can engage in various inter-Korean cooperations in non-political and non-military areas. Namely, local governments need to focus on establishing durable relations with the North to maintain mutual trust. Local governments can acquire the maximum effects with their limited resources, as they place an emphasis on social and cultural exchanges and humanitarian aid. This kind of two-track approach might be too simple and too mechanical. Nevertheless, it can optimize the role of local government in inter-Korean cooperation.

N/A For evaluating the efficacy of teprenone for gastric ulcer, we prescribed 50 mg of teprenone orally three times daily for 16 gastric ulcer patients and done follow up studies including gastric and biochemical tests. The results obtained were as follows: 1) Gastroscopic examination revealed remarkable improvement in 31.3% and moderate improvement in 25.0% of patients during 8 weeks. 2) Subjective symptoms such as epigastric pain, nausea, vomiting, anorexia and belching were subsided from 68.8% to 100% of patients. 3) No remarkable side effect were noted. These results suggest that teprenone is one of effective therapeutic drugs for gastric ulcer patients.
