전분중에 함유된 Amylose와 Amylopectin의 분리에 관한 연구(Ⅰ)
張慶貞 배화여자대학 1983 培花論叢 Vol.2 No.-
The chemical compositions, blue value and alkali number of starch were measured in such grains as rice, glutinous rice, barely, wheat, potato, mung bean. The potato starch was chosen for the separation of amylose and amylopectin in this experiment. In the purification process, (1) the concentration of methanol and butanol on separation of amylose and amylopectin; (2) the changes in blue value and alkali number of amylose and amylopectin were measured. 1. The following results were obtained in regards to the chemical composition and blue value & alkali number as follows. (1) Moisture; 11.76% in rice, 12.65% in glutinous rice, 9.88% in barley, 12.6% in. wheat, 81.2% in potato, 11.9% in mung bean. (2) Ash; 0.46% in rice, 1.45% in glutinous rice, 1.63% in barley, 1.8% in wheat, 3.245% in mung bean. (3) Protein; 5.83% in rice, 7.2%in glutinous rice, 8, 75% in barley, 11.5% in wheat, 1.75% in potato, 23.58% in mung bean. (4) Reducing sugar; 11% in rice, 11.1% in barley, 10.8% in wheat, 0.98% in. potato, 0.15% in mung bean. (5) Alkali number; 9.6 in rice, 3.6 in glutinous rice, 9.0 in barley, 8.2 in wheat, 4.8 in potato, 10.6 in mung bean. (6) Blue value; 0.316 in rice, 0.065 in glutinous rice, 0.647in barley, 0.652 in wheat, 0.374 in potato, 0.438 in mung bean. 2. The result from the separation of amylose and amylopectin from potato starch were as follows; (1) The complete precipitation of amylose was at the addition of 80m1 butanol per 10g of centrifuged precipitation. (2) The complete precipitation of amylopectin was at the addition of 70ml Methanol per 10ml of centrifuged precipitation. (3) The blue values of amylose from the 2nd purification showed much difference from those of the initial purification but there was little differences between the blue values of 2nd and 3rd purification. (4) Blue value of amylopectin showed little difference between each progressing purification. (5) Amylose showed the progressively increasing alkali numbers whereas amylopectin showed the gradually decreasing alkali numbers through a complete purification process. Based upon the results obtained, it was necessary to conduct a minimum of three progressive purifications of amylose and amylopectin in order to complete a thorough purification process.

It is important for nurse to take meticulously care the patient who has suffered from severe lumbago and sciatica. Conservative TX has net always been successful for such patients who were diagonsed as the vertebral disc herniation. There for, surgical intervention has been routine procedure in neurosurgical field. A total number, of 405 cases with ruptured or protruded lumbar intervertebral disc operated on from August 1964 to July 1973 is analysed in this report: Male is dominantly affected in this group. Among the age range from 17 to 78 years old, young adult, 31∼40 years of age, is involved most often. Nursing care including psychological approach has been most important before, during and after surgery, because the patient is always allert during the surgery under local anesthesia. O. P. table nurse must pay attention in catching every complaint and information from patient in order to relieve patient's temper during surgery.
