RESUMO
The self-designed experiments of extract preparations is practiced in pharmacy teach-ing. Students work in groups, first consulting literature material, selecting the prescription and devis-ing a plan. Then, if the plan has carried on the feasible proof, students begin to purchase raw materi-als, complete the extraction and separation of effective components, the preparation of molding and the analysis of experimental results and finally form their self-evaluation. This experiment can strengthen students' experiment skill and promote their comprehensive application ability of all the subjects in the pharmacy field. At the same time it can also play an important role in the improvement of the students' social practice ability and the cultivation of students' creative thinking.
RESUMO
The only extract preparations listed in either the “Shokan-ron” or the “Kinki-yoryaku” are the “Daio-oren-shashin-to.” It is thought that the term “extract preparation” is used because of the speed of efficacy required of these formulas. The author tried three different varieties of these percolate extracts, “Daio, ” “Oren, ” and<br>“Ogon, ” in a group of hypertensive patients (5 men, 27 women). Blood pressure was measured both 30 minutes before and after administration. As a result, an antihypertensive effect of 10mmHg systolic blood pressure or more was seen across 68.8% of the group. There was even an antihypertensive effect in those not normally considered “Yo-jisshou” (resistant and robust constitution). And with this administration, none of the patients developed diarrhea. Extract preparations seemed to have more of an enhancing effect on sedative action, rather than on purgative action. And they are considered effective as antihypertensive agents in emergency cases of elevated blood pressure.
