As a health care measure for the people in the prime of life, the Ministry of Health and Welfare (now the Ministry of Health, Labor and Welfare) of the Japanese government started off the first 5-year program for the senior citizens in 1983 with the enforcement of the Law Concerning Health and Medical Services for the Aged, followed by the second five-year program in 1988 and the third eight-year program in 1992. The screening project for colon cancer was incorporated in the third program with a target set of holding an increasing rate of morbidity at zero in a year-to-year comparison. The response rate to colon cancer screening (the ratio of the number of participants responding to colon cancer screening to the total number of qualified persons) was also to be raised steadily to reach a target of 30% in 1999. In Gifu Prefecture, the total number of examinees in 1999 increased twice the figure in 1992, but the response rate was 14.8%, which was only about half the target and below the national average of 15.3%. The detection ratio of colon cancer and the early cancer ratio in the prefecture were much the same as the national average. It could be taken that there is nothing wrong as far as the precision of screeming and management are concernd. To decrease the rate of mortality from cancer of the colon, the most important is to raise the response rate. For this purpose, we would like to propose that the cost should be covered by national health insurance in those health screening projects approved of by the competent authorities.

Daikenchuto is recorded in Kampo textbooks as a prescription for abdominal disorders. We considered fukuchukan (coldness in the abdomen) as equaling a sensation of coldness centering on the navel, and we examined the usefulness of using Daikenchuto as a medication for this symptom. We administered Daikenchuto to 90 patients who presented with coldness of the navel. The patients were divided into 2 groups:the first group had accompanying digestive symptoms, the second had no accompanying digestive symptoms. We then examined their response rates, and improvement rates for coldness centering on the navel. We also examined the abdominal strength and pulse strength for responders and non-responders, respectively.The Digestive Symptoms group consisted of 64 patients. In this group, the response rate was 81.3%.The improvement rate of coldness centering on the navel was 92.3% in responders and 41.7% in non-responders, and the difference was highly statistically significant (p<0.001). The Non-digestive Symptoms group consisted of 26 patients. In this group, the response rate was 38.5%. The improvement rate of coldness centering on the navel was 100% in responders and 43.8% in non-responders, and the difference was statistically significant (p=0.022).In a comparison of all 90 responder and non-responder cases, weak abdominal strength was 62.9% in responders and 42.9% in non-responders, intermediate abdominal strength or above was 37.1% in responders and 57.1% in non-responders, and the difference between abdominal strength and response rate (p=0.076) was non-significant. Weak pulse was 54.8% in responders and 40.7% in non-responders, intermediate pulse strength or above was 45.2% in responders and 59.3% in non-responders, and the difference between pulse strength and response rate (p=0.221) was non-significant. 13 of these cases were above intermediate, for both abdominal strength and pulse strength.We conclude that for patients presenting with a sensation of coldness centering on the navel, there is a strong possibility that the efficacy of Daikenchuto-syo is suggested, regardless of whether or not there are other digestive symptoms. Moreover, Daikenchuto proved effective in 13 cases where both abdominal strength and pulse strength were above an intermediate level, suggesting that a sensation of coldness centering on the navel can be the key to finding the sensho of Daikenchuto-sho.
