PURPOSE: The aim of this work was to study the change in antioxidant activity depending on storage temperature and storage period in romaine and cherry. METHODS: The plant material was stored at 0.7 +/- 0.6degrees C, 3.5 +/- 2.8degrees C, and 4.7 +/- 1.4degrees C. Cherry and romaine were stored for a period of 9 days and 7 days, respectively. The cherry was taken from each group of samples at regular intervals of days and the romaine was taken from each group of samples at regular intervals of 2days. Vitamin C, total polyphenol, and total flavonoid stability and antioxidant capacity including DPPH, total antioxidant capacity (TAC) were measured. RESULTS: For cherry, the levels of TAC and flavonoid were higher at the 0.7 +/- 0.6degrees C condition than other conditions (p < 0.05). The polyphenol and vitamin C levels were not significantly different among storage conditions. In the case of romaine, the level of TAC was highly preserved until 7 days at the 0.7 +/- 0.6degrees C condition. Vitamin C level was significantly lower at the 3.5 +/- 2.8degrees C condition (p < 0.05). DPPH activity was highest at the 0.7 +/- 0.6degrees C condition (p < 0.05). DPPH activity was shown in order of 0.7 +/- 0.6degrees C > 4.7 +/- 1.4degrees C > 3.5 +/- 2.8degrees C. CONCLUSION: The results indicated that the narrow differences and fluctuation in temperature were associated with antioxidant capacity and it might enhance the nutritional shelf life of vegetables and fruits.

The use of near infrared (NIR) spectroscopy was proved to be a useful tool for quality analysis of fruits. A bifurcated fiber type NIR spectrometer, with a detection range of 800~2500 nm by InGaAs detector, was used to evaluate the firmness of peaches. Anisotropy of NIR spectra and firmness of peaches in relation to detecting positions of different parts (including three latitudes and three longitudes) were investigated. Both spectra absorbency and firmness of peach were influenced by longitudes (i, ii, iii) and latitudes (A, B, C). For modeling, two thirds of the samples were used as the calibration set and the remaining one third were used as the validation or prediction set. Partial least square regression (PLSR) models for different longitude and latitude spectra and for the whole fruit show that collecting several NIR spectra from different longitudes and latitudes of a fruit for NIR calibration modeling can improve the modeling performance. In addition, proper spectra pretreatments like scattering correction or derivative also can enhance the modeling performance. The best results obtained in this study were from the holistic model with multiplicative scattering correction (MSC) pretreatment, with correlation coefficient of cross-validation r(cv)=0.864, root mean square error of cross-validation RMSECV=6.71 N, correlation coefficient of calibration r=0.948, root mean square error of calibration RMSEC=4.21 N and root mean square error of prediction RMSEP=5.42 N. The results of this study are useful for further research and application that when applying NIR spectroscopy for objectives with anisotropic differences, spectra and quality indices are necessarily measured from several parts of each object to improve the modeling performance.

OBJECTIVETo develop an UPLC method of determining the characteristic chromatographic profile of Persicae Semen for controlling the drug quality quickly and accurately.

METHODThe UPLC characteristic chromatographic profiles of fifteen batches of Persicae Semen were determined on an HSS T3 column (2.1 mm x 100 mm, 1.8 microm) eluted with the mobile phase consisted of acetonitrile-water containing 0.05% phosphoric acid in gradient mode and the detection wavelength was at 254 nm.

RESULTThe common mode of the UPLC characteristic chromatographic profile was set up. There were 12 common peaks in the fingerprints of fifteen samples, six of which were identified, and the similar degrees of the fifteen batches to the common mode were between 0.884-0.996.

CONCLUSIONThe method was quick and accurate. The characteristic chromatographic profile of Persicae Semen with high specificity can be used to control the quality of Persicae Semen.

Contact urticaria designates a local immediate and/or delayed urticaria reaction, with swelling and redness at the sites of contact with certain agents. Fruits are the frequently causative agent for immunologically mediated contact urticaria. We report herein a contact urticaria occurring in a 20-year-old male immediately aftar contact with peach and plum, and after ingestion of plum, peach and apple. Swelling and itching sensation of lips and oral cavity, and tightness of chest were also developed ofter ingestion of plum, peach and apple.

The authors present seven cases of Democidiosis in rosacea type and the subject of human demodetic infestation has been reviewed. According to our experience, demodex folliculorum, although a normal inhabitant of the sebaceous glands in small numbers, when encouraged to multiply by the patients excessive use of facial cream and avoidance of soap, can produce democidiosis. The diagnosis was easily confirmed by characteristic clinical appearance and simple microscopy. The characteristie clinical appearances are indurated non-comedous papules and pustules with unique cherry pinkish red erythema. The response to treatment, consisting of daily soap and water cleansing of the face, followed by the local application of a suitable antiparasitic remedies is simple and gratifying. But the erythema was not respond to antiparasitic preparation.

The purposes of this study were to determine phenolic compounds and to evaluate antioxidant activities of plums (Soldam, Oishiwase and Formosa). Soldam contains the highest amount of total phenolics among cultivars (Formosa: 4.0%, Oishiwase: 3.3%, Soldam: 6.4% for total phenolic) as well as the total flavonoids of which constituents were mainly myricetin and anthocyanidin. The antioxidant activities were measured by DPPH, ABTS radical scavenging, and SOD-like activities. The DPPH radical scavenging activity of Korean plum extracts (200 microg/mL) showed more than 43%, and the Soldam turned out to be the highest : ID50 value: 160-177 microg/mL for Formosa and Oishiwase; 58-64 microg/mL for Soldam. The ABTS radical scavenging activity of Korean plum extracts (200 microg/mL) was found to be more than 50%. The SOD-like activity of Korean plum extracts (200 microg/mL) showed more than 70%. Among three kinds of cultivars, Soldam had the highest antioxidant activity. The nitrite scavenging activity of Soldam was 61.5%, which is the highest, compared with that of the other cultivars, about 50%. From these results, Korean plums turned out to be phytochemical rich fruit as well as to show high antioxidant activities.

Glassy cell carcinoma (GCC) of the uterine cervix is a rare and highly malignant tumor, accounting for only 1%~2% of all cervical carcinomas. It is typically composed of malignant cells having a moderate amount of cytoplasm with "ground glass" appearance, distinct cell membranes that stain with eosin or periodic acid-Schiff, and large nuclei with prominent nucleoli. Since its original description in 1956 by Glucletmann and Cherry, 200 - 250 cases of GCC of the uterine cervix have been listed in the literature. We report here the clinicopathological study of one case of glassy cell carcinoma with brief review of the literature.

Cardiac papillary fibroelastoma rarely occurs. A 63-year-old otherwise healthy man presented with sudden loss of consciousness and right hemiparesis. Echocardiography showed a small freely movable round mass attached to the septal side of the left ventricular outflow tract. At surgery, it was revealed to be a small round mass with a thin elongated stalk resembling a cherry. The pathologic findings were characteristics of a papillary fibroelastoma.

Atrophic dermatofibrosarcoma protuberans is a rare variant of DFSP, which presents as a depressed violaceous scar like lesion with atrophic plaque. Although atrophic DFSP is identical to classical DFSP in location, treatment, prognosis and histology, clinical diagnosis is sometimes difficult for the atrophic lesion. We report a 36-year-old male presented with asymptomatic firm violaceous depressed atrophic lesion and a skin colored almond shaped, subcutaneous nodule on the left subclavicular area. Histopathologically the tumor shows the spindle-shaped cell arranged in cart wheel pattern. The tumor cells were stained positively for CD 34 on immunohistochemical stain.
