We investigated the history and indications of Toenho, Kinseiho, and Cho-Sanshaku-Shinteiho, which are different formulae with the same name of seishoekkito. According to the description in “Futsugoyakushitsuhokankuketsu” written by Sohaku Asada, Kinseiho exhibits an immediate effect, while Toenho has preventive effects. However, according to the original text, Kinseiho was formulated such that it could be administered regularly in the summer for prophylaxis. Furthermore, Kinseiho is regarded as a simplified formula with the central structure of Toenho. This implies that Kinseiho is composed of selected crude drugs used in Toenho that are responsible for the main effects of Toenho, such as invigorating spleen energy, clearing fever and generating body fluids. Moreover, there is an instruction to arrange Kinseiho to fit each patient’s condition. In this study, it was found that Cho-Sanshaku-Shinteiho described in “Futsugoyakushitsuhokankuketsu” is a modification of Kinseiho prescribed by Katsuki Gyuzan for patients with fever, consistent with the concept of personalized medicine. The medical extract preparation seishoekkito, which is currently widely used, is Kinseiho. We may use it with heat-clearing formula, fluid-regulating formula or some modifications to make the appropriate formulation based on the patient's symptoms.

Soshikokito has long been used to treat cough in frail patients with cold sensation in their feet, based on the Japanese traditional Kampo textbook “Iryo-Shuhou-Kiku”. In many old documents including “Wazai-Kyokuho,” where soshikokito was first described, it is suggested that airways obstructed by a large quantity of watery expectoration should be the proper indication for the use of this formula. However, in the five cases that we successfully treated, the quantity of sputum was relatively small. To determine the practical indications for this, we examined their abdominal strength and the presence or absence of “cold feet” sensation. In addition, we investigated the nature of sputum in the past clinical reports in which successful treatment using soshikokito was described. It has become clear that we can prescribe soshikokito as an antitussive regardless of the patients' physical fitness as deduced from the abdominal strength. The “cold feet” sensation was not an essential symptom and was regarded as one of the symptoms of qi counterflow. Regarding the properties of sputum, it was viscous and small in quantity. In the cases where soshikokito was effective, it was speculated that viscous sputum would result in airway obstruction, coughing, and wheezing. These conditions will be ameliorated by the antitussive and expectorant effect of this formula, which improves qi counterflow and mildly tonifies water. In the treatment of cough with respiratory distress, “sputum with high viscosity and hard to discharge” is considered to be the targeted symptom in the practical usage of soshikokito.

The rectal tonsil is a rare polypoid lesion exclusively found in the rectum and is considered a reactive proliferation of the lymphoid tissue. Although this lesion is benign, we recommend that it should be differentiated from carcinoid or polypoid type of mucosa-associated lymphoid tissue lymphomas, based on gross findings. In this case report, we describe a case of rectal lesions with a unique appearance in a 41-year-old man. Colonoscopy revealed two 5-mm-sized nodules located opposite from each other on the left and right sides of the lower rectum. Endoscopic mucosal resection was conducted. Histopathologically, both lesions were mainly located in the submucosa and consisted of prominent lymphoid follicles with germinal centers of various sizes. No immunoreactivity of Bcl-2 was seen in the germinal centers. Immunohistochemical staining for kappa and lambda light chains revealed a polyclonal pattern. Therefore, these lesions were diagnosed as rectal tonsils.

We report a case of prolonged lumbago with severe cold intolerance successfully treated with keppuchikuoto and uzushakusekishigan. The patient was a 71-year-old female with lumbar spinal canal stenosis which was refractory to several nerve and intervertebral disc block therapies and oral medications. She had been also suffering from constipation, leg cramps, intermittent chest pains, and severe cold intolerance. We prescribed keppuchikuoto for chronic blood stagnation and deficiency and uzushakusekishigan for intermittent chest pains in order to improve those symptoms all together. The severity of her lumbago and severe cold intolerance were remarkably reduced after the administration of the two formulas. This case suggests that the two formulas exerted their effectiveness by ameliorating chronic severe cold intolerance, blood stagnation, and blood deficiency and resulted in remarkable improvement in lumbago.

BACKGROUND: The purpose of our study was to compare the characteristics of medical practitioners who prefer using the Internet as their information resource and those who prefer using printed materials.
METHODS: From December 2002 to January 2003, a non-anonymous questionnaire was sent out by post to members of the Japanese Medical Association (JMA) and physicians working in hospitals. Contributing factors were examined by using logistic regression analysis.
RESULTS: The response rates for the questionnaires were 18.7% (n=1868) for JMA physicians and 68.0% (n=5901) for hospital physicians. Factors associated with the preference for using the Internet were: ‘younger age’; ‘use of the Internet to solve clinical problems and uncertainties’; ‘use of personal computers at work’; and, ‘use of personal computers at home’.
CONCLUSION: The results of this study show that, although some younger physicians prefer printed materials, providing medical information via the Internet is better suited for younger physicians who are making full use of computers. In contrast, older physicians prefer printed materials because they tend to be less familiar with using computers and may have limited accessibility to the Internet. Therefore, using both the Internet and printed materials to provide medical information is necessary to meet the needs of the larger physician population.

Though preoperative autologous donation is not acceptable for all cases partly because some are preoperatively in a severe condition, intraoperative predonation is possible in almost all cases. We retrospectively evaluated the major factors related to the prevention of homologous blood transfusion by intraoperative predonation in 25 cases following valvular surgery without preoperative autologous donation. Homologous blood was not transfused in 18 cases {Group-(-)} but in 7 cases only after CPB {Group-(+)}. The male/female ratio, type of operation, body weight, CPB dilution, CPB duration, and perioperative change in hematocrit were comparable in the 2 groups. However, the autologous blood pooled before CPB in Group-(-) was significantly more than in Group-(+) (11.3±2.5 vs 7.3±1.8ml/kg, p<0.001). In conclusion, homologous blood transfusion may be prevented by appropriate intraoperative predonation during surgery for valvular disease.

BACKGROUND: physicians' awareness regarding evidence-based medicine (EBM), clinical practice guidelines, and clinical information resources were rarely examined in Japan. We need to know them prior to the initiation of the Medical Information Network Distribution Service (Minds) by the Japan Council for Quality Health Care (JCQHC) .
METHODS: A total of 10, 000 directors/owners of private clinics (CDs: clinic physicians) affiliated with the Japan Medical Association (JMA) and 8682 physicians working for hospitals certified by the JCQHC (HDs: hospital physicians) were randomly selected and surveyed by a mailed questionnaire.
RESULTS: The response rate to the questionnaire was 18.7% (n=1865) among CDs and 67.8% (n=5885) among HDs. The percentage of respondents who uses internet was 39.9% among CDs and 69.3% among HDs. The information resource most commonly used by all respondents was medical journals, followed by textbooks. The percentage of respondents who used medical literature database was 10.8% among CDs and 49.7% among HDs, respectively. Approximately 80% of all respondents approved implementing EBM in daily practice. Fifty percent of all respondents indicated to have used clinical practice guidelines, and 90% of all the guideline users replied that clinical practice guidelines are useful tools for clinical decision-making. Over half of HDs required to access to the abstracts of the literature cited in the guidelines.
CONCLUSIONS: Many physicians who responded to the survey acknowledged that EBM will contribute to improving the quality of medical services. They are positive in using clinical practice guidelines that include a series of recommendations proposed by specialists in the relevant field (s) in accordance to the reviewed evidence.

Three main factors that sway the postoperative prognosis of stomach cancer are, the curability of the surgical operation, the depth of the cancer lesion and the stage of the disease. With these factors in mind, we further studied what other factors could influence the long-term prognosis of stomach cancer.
We picked up two categories of patients from our file of stomach cancer cases. Category one; those patients who survived five years or longer after surgery, although the operations for them were not curative, or the depth of the lesion in these patients reached to the serosa, or the cancer was in stage IV. Category two; those patients who died of stomach cancer within five years after surgery, although the operations were curative, or the depth of the lesion reached only the submucosal layer, or the cancer was in stage I.
By comparing these two groups, we found out the factors that influence the prognosis.
1) In the cases of absolutely curative operations, the factors that made the prognosis worse, were that the lesion was advanced, that the lesion existed in the C region, and that the lesion was poorly differentiated histologically.
2) In the cases of noncurative operations, caused by P1, H1, ow (+) or aw (+), factors that brought a good prognosis were, that the lesion was not of diffuse type, that there was no lymph node metastasis, and that lymph node dissection was done effectively.
3) In the cases of early gastric cancer, lymph node metastases made the prognosis worse. Even when the lesion reached the serosa, prognosis was favorable if cancer cells did not invade other organs, had no peritoneal dissemination, or if lymph node dissection was perfect.
4) In the cases of stage I histologically, prognosis was poor when the cancer looked advanced to the naked eye.
5) In the cases of stage IV, when the degrees of lymph node metastasis was slight and lymph node dissection was done adequate, prognosis was good.

During the twelve years from January 1978 to December 1989, a total of 1, 409 cases of gastric cancer were treated in the surgical department of Tsuchiura Kyodo Hospital, located in the southern agricultural district of Ibaraki Prefecture.
Observations on these cases revealed: 1) Cases of gastric cancer tend to decrease, 2) Results of surgical treatment are improving remarkably, in terms of the resection rate and five-year survival rate, and 3) Most of the patients who survived more than five years after surgery are in satisfactory conditions.
The main factor contributing to the improvement of the results of surgical treatment of gastric cancer was increased detections of cancer in relatively early stages through mass survey or total check-up in the asymptomatic stage.
The decline of the morbidity rate of gastric cancer is reported to be more prominent in younger generations. This fact and the aging of the population in our society, especially in rural areas, will increase the number of elderly gastric cancer patients.
The future of surgery of gastric cancer depends on how early we can detect cancer and treat elderly patients. For this purpose, mass survey and total check-up on older people will be the most effective means.

During the eleven years from January 1978 to December 1988, we experienced 1, 287 cases of gastric cancer, hospitalized in the surgical department of Tsuchiura Kyodo Hospital which is located in the southern agricultural district of Ibaraki Prefecture.
Among these 1, 287 cases, 1, 233 patients were operated on. Gastric resection was performed in 1, 059 cases including 337 cases of total gastrectomy with the resection rate of 85.9 percent (1, 059/1, 233). In 863 cases, resection gave histologically satisfactory results, and our curative resection rate was 70.0 percent (863/1, 233). Direct mortality rate was 2.35% in all operated cases and 1.32% in resected cases.
The five-year survival rate over the period from 1978 to 1983 was 57.7% in all resected cases and 69.3% in curatively resected cases.
Annual follow up observation showed increases in resection rate, curative resection rate, and five-year survival rate. However, there were no remarkable changes in the rate of total gastrectomy, rate of combined resection of other organs, and degree of lymph nodes dissection.
The main factor contributing to the improvement in the results of surgical treatment of gastric cancer was the increase in the detection rate of cancer in relatively early stages, through gastric mass survey or total check-up in the asymptomatic stage.
