Reflections on the Education of Humanities Concern to the Oral Medical Students / 昆明医科大学学报

Humanistic spirit advocates the concern for human,and the medical value of people foremost.Now status quo of oral medical students' humanities concern is worrying.This paper aims to analyze the reason,and the best way to culture oral medical students' humanities concern is not only to have an aim of training medical professionals who have oral medical knowledge and skills,but also to look upon the education of medical humanistic spirit as important educative content,to improve teachers' humanities diathesis,to enhance the contact between medical students' and society or patients,to foster affection,to train skills,and to establish the good environment of humanities education.

THE EFFECTS OF A CONTROLLED pH ENVIRONMENT ONPOLYSACCHARIDE SYNTHESIS BY AUREOBASIDIUM PULLULANS / 微生物学通报

The effect of pH on the extracellularpolysaccharide synthesis by Aureobasidium pullulans was studied by addding CaCO3and HCI. Cultivated in P2 liquid medium for 24h,pH dropped to 3. 6 because of strongly producing acid. Under this low pH environment, further fermentation for 120h,only 5. 9g/L of polysacharide was obtained. When grown in MP2 medium contaning0. 5 % CaCOs,the pH was kept above 5.0 during 144 hours,production of polysaccharide increased to 31g/L. The detailed information of effects of controlled pH on polysaccharide production showed an optimal pH value 5. 0 must be maintained through the fermentative period.

THE EFFECTIVENESS AND TOLERANCE OF ORAL SODIUM PHOSPHATE FOR COLONOSCOPIC PREPARATION / 中华消化内镜杂志

For investigating the effectiveness and safety of oral sodium phosphate in preparation for colonoscopy,108 cases from both outpatient and inpatient clinics from June,1995 to March,1996 were randomized and blinded to receive either oral sodium phosphate or standardized electrolyte lavage solu- tion as control.The questionaire was designed for scoring by patients and doctors regarding to its toler- ance,taste,side effects and cleaning degree etc.Results showed that the tolerance rates in oral sodium phosphate and electrolyle lavage were 87.5% and 69.2% and the rates of preference in using them were 32.2% and 15.4% respectively(P
