1) The historical development to date of the systems of medical education and medical licensure were reviewed, and the quantitative and qualitative evolution of medical schools was divided into 7 stages.2) In the early Meiji era, persons who had already practiced medicine could apply to receive a medical license. Until the Taisho era, medical licenses were granted either to graduates of medical universities and relevant special schools or to those who passed the national examination. Thus, the criteria for medical license were not uniform during this period.3) Before the end of World War II, medical schools aimed to improve the quality of medical education so that their graduates could receive medical licenses without taking the national examination and to raise their status to the level of universities. However, because the types of medical schools during this period varied and included imperial universities, colleges, and specialty schools, the quality of medical education also varied.4) After World War II, the introduction of the state examination for the license to practice medicine and a new university system standardized medical education to guarantee its quality.5) The quantitative expansion of the medical education occurred mainly in the 12 years after 1919, in the 7 years after 1939 and during the war, and in the 10 years after 1970, and, except for the years of violent change before 1887, the number of medical schools has otherwise remained stable.

This study was conducted to shed light on the actual conditions of home care and quality-of-life factors related to the burdens on families. For this purpose, a survey was carried out on main caretakers in the families who were using our home care support service. Fundamental information about the main caretakers and those who need care were garnered. In addition, WHO/QOL-26 and burdens for main caretakers were checked up on.The survey found that those who have looked after the sick or invalid for less than six months and those over five years keenly felt that they were shouldering a heavy burden. With the progression of dementia, the caretakers increasingly felt the burden getting heavier. Physical factors in QOL were linked to the burden which caretakers feel has to be borne, but psychological and social factors were not. This finding might have been ascribed to the fact that the persons surveyed were residents of the provincial city, part of which is rural. They were mostly old women and must have gained the support of their relatives. It is easy to assume that their role perception and sense of responsibility together with regional characteristics were reflected in psychological and social QOL factors.

Prostaglandin E₁ (PGE₁) was used continuously in adults from immediately after induction of anesthesia, during extracorporeal circulation, to the acute phase after open heart surgery. Using blood flow in the toe determined by laser Doppler flowmeter and the temperature difference between periphery and core as indices, the effects of afterload reduction and improvement of peripheral circulation were investigated. Subjects were 17 adults who underwent open heart surgery. PGE₁ was used in 7 patients and not used in 10. In the group using PGE₁, continuous injection of 0.015μg/kg/min of PGE₁ was started immediately after induction of anesthesia and was maintained during extracorporeal circulation until the acute phase after surgery. During extracorporeal circulation, perfusion pressure was kept at 50∼60mmHg and PGE₁ injection was controlled within the range of 0.015∼0.030μg/kg/min. At completion of extracorporeal circulation, the dose was fixed at 0.015μg/kg/min again. The degree of improvement of peripheral circulation was evaluated on the basis of hemodynamics, blood flow in the toe determined by laser Doppler flowmeter and the temperature difference between periphery and core, at induction of anesthesia (before using PGE₁) on completion of extracorporeal circulation, and in the acute phase after surgery. The value of blood flow in the toe determined by laser Doppler flowmeter was significantly higher in the PGE₁ group than in the non-PGE₁ group, from completion of extracorporeal circulation to the acute phase after surgery. Moreover, peripheral temperature was significantly higher in the PGE₁ group than in the non-PGE₁ group at completion of the extracorporeal circulation as well as immediately after surgery, and the temperature difference between periphery and core was significantly smaller. Continuous injection of PGE₁ enabled smooth control of perfusion pressure during extracorporeal circulation. Although there was no significant difference in peripheral vascular and total pulmonary resistance, the coefficients tended to be lower in the PGE₁ group. The use of PGE₁ during open heart surgery seems to be an effective method to improve peripheral circulation.
