        The purpose of this study was to evaluate the effects of pulsed ultrasound on wound healing and observe during the wound healing process the distribution of mast cells according to histopathologic findings. Eighty Sprague Dawley rats which were divided into 4 groups received full thickness skin wounds on the back. Each of the 5 animals was sacrificed immediately and then sacrificed again 1, 3, 6, and 12 days after injury. Specimens from the wounds were removed during healing and routinely processed with a hematoxylin-eosin stain and a toluidine blue stain. The authors then observed the distribution of mast cells under a light microscope. The results of this study were as follows: The rate of wound healing and the length of the wounds of the pulsed ultrasound group II was significantly faster than group I on day 6 and day 12 (p<.001). Group III showed the most significant effect after12 days (p<.001). Group IV also showed a significant effect at 12 days (p<.01). A low-intensity ultrasound .5 resulted in a fast healing rate. During the wound healing process mast cells had a tendency to decrease in the acute inflammatory phase. During the wound healing process mast cells were thought to contribute to the healing of the wound.

        Kim, Kyung Suk. 2004. The Portrayal of Korea in an English- English Dictionary. The Sociolinguistic Journal of Korea, 12(2). This paper examines the sentences relevant to Korea which were found in a search of an English-English dictionary to see how they portray Korea. One hundred nineteen sentences were obtained from the CD-ROM version of Collins-Cobuild English Dictionary for Advanced Learners (2001) and they were judged as to whether they present positive, neutral, or negative images. The majority of the sentences (73/119) have neutral portrayals. Among the remaining sentences, 12 are positive and 34 are negative. When the data are sub-categorized into three groups, it becomes obvious what the positive and negative sentences in the data reflect in general. Nine positive sentences out of the total 12 positive ones are relevant to the activities/people of the Republic of Korea. Twenty-four of the negative sentences include the generic expressions of Korea referring to both South and North Korea (e.g., Korean peninsula or Koreans) or phrases referring to North Korea more explicitly. When we look more closely at the negative sentences, it is found that they are mostly related to the political tension or military conflicts between South and North, which happened quite a while ago and which we have fully recovered from. In order to prevent those sentences from leaving a potentially bad imprint on the users of the dictionary, we need to give feedback to the publisher about the results of this line of research and ask them to replace the sentences with positive/neutral sentences when they update the dictionary.

        The purpose of this study was to investigate the dietary and the living habits of 606 university students located in the Chonnam area. The subjects included 290 freshmen (47.9%) and 316 undergraduate students (52.1%). This survey was conducted using a self-administered questionnaire. Most students (73.9%) skipped breakfast because of lack of time (65.8%) of the cases. Self-reported eating habits problems were eating irregular meal (52.8%), overeating (21.1%), unbalance diet (13.0%) and skipping meal (7.3%). The type of favorite snack was biscuit (31.8%) and cup Ramyon(31.8%). The weight control was higher in freshmen compared to undergraduate. The rates of smoking in freshmen and undergraduate were 21.0% and 26.6% respectively. The coffee intake and alcohol drinking frequency was higher in undergraduate compared to freshmen. The living habits of undergraduate students were undesirable. Therefore they should have a nutritional program to improve their food habits and the dietary behaviors for students' health. And nutritional education program should be organized practically and systematically.

        Atrial natriuretic peptide (ANP), a circulating peptide hormone with 28 amino acids secreted from cardiac atria, plays an important role in the maintenance of fluid and electrolytes homeostasis. The actions of ANP appear to be mediated by specific receptors on target cells. However, the specific antagonist for ANP receptors is not yet to be defined. The present study was undertaken to evaluate the antagonistic effects of water extract obtained from the gardenia (Gardenia jasminoides Ellis) on the natriuretic peptide receptor system in the kidney. In the kidney of Sprague Dawley rats, specific 125I-ANP binding sites were localized in glomerulus, inner medulla, intrarenal artery, and vasa recta bundle by using quantitative in vitro receptor autoradiography. These specific bindings were competitively displaced in a dose dependent manner by water extract obtained from the gardenia. Moreover, productions of 3',5'-cyclic guanosine monophosphate (cGMP) via activation of particulate guanylyl cyclase (GC) by ANP were increased in receptor proteins from the glomerulus and inner medulla of rat kidney. These cGMP productions were inhibited in a dose dependent manner by water extract obtained from the gardenia. The inhibitory effect of water extract obtained from the gardenia on activation of GC was quantitatively more potent rather than on 125I-ANP bindings to these renal structures. From affinity cross-linking study on the specific receptor proteins, the water extract obtained from the gardenia inhibited the 125I-ANP labeling of GC-coupled natriuretic peptide receptor from renal glomerulus of rat. Intravenous infusion of ANP elicits the potent diuresis, increment of urine osmolariry, and excretions of urinary chloride, creatinine and PAH in New Zealand White rabbit. These renal effects of ANP were inhibited by the intravenous pre-treatment of water extract obtained from the gardenia without changes in systemic hemodynamics including mean arterial blood pressure and heart rate. These results indicate that the water extract obtained from the gardenia may could be block the GC-coupled natriuretic peptide receptor, and suggest that the extract may contain a natural antagonistic molecule regulating the renal natriuretic peptide system.

        The present study was undertaken to evaluate the antagonistic effects of water extracts of Chinese gooseberry (Actinidia chinensis P.) root on the natriuretic peptide receptor system in the rat kidney. By using in vitro receptor autoradiography, specific 125I-atrial natriuretic peptide (125I-ANP) binding sites were localized in glomerulus, inner medulla, intrarenal artery, vasa recta bundle, and renal pelvis of Sprague Dawley rat kidney. These specific bindings were competitively displaced by water extracts of Chinese gooseberry root in a dose dependent manner. Also, productions of 3',5'-cyclic guanosine monophosphate (cGMP) by activation of particulate guanylyl cyclase (GC) were stimulated by ANP in the glomerular and inner medullary membranes from rat kidney. These cGMP productions were inhibited by water extracts of Chinese gooseberry root in a dose dependent manner. The inhibitory effect of water extracts of Chinese gooseberry root on activation of GC was more potent rather than on 125I-ANP bindings to these renal structures. From affinity cross-linking study, the water extracts of Chinese gooseberry root inhibited the 125I-ANP labeling of GC-coupled natriuretic peptide receptor from renal glomerulus. Intravenous infusion of ANP elicits a potent diuresis, and urinary sodium and chloride excretions in New Zealand White rabbit. The pre-treatment of intravenous water extracts of Chinese gooseberry root infusion decreased competitively various renal effects of ANP with out changes in systemic hemodynamics. These results indicate that the water extracts of Chinese gooseberry root specifically inhibits the GC-coupled natriuretic peptide receptor subtypes (NPR-A), and suggest that the water extracts of Chinese gooseberry root may contain an antagonistic molecule regulating the biological functions of ANP system in the kidney and other organs.
