The purpose of this study was to develop an information system about drugs. The Joint Application Design Method which is popular in developing information systems was used. This system will be useful for the health care personnel and nursing students with easy access to information by using computer. The user requirements for this system were collected and analyzed through a survey of 50 nurses in a hospital and 30 students at a school of nursing. Based on this analysis, the specific contents were designed. The characteristics of this system as follows. Firstly it is the fast searching function which uses not only names of drugs(generic name, functional name, commercial name), but also names of diseases. Secondly, it is the function which maintains an updated database by the way of adding, updating and deleting the data. Thirdly, this system is useful for the education. In teaching and learning process, Computer-Assisted Instruction(CAI) is considered as one of the outstanding method bacause the individual differences in learners are respected and thus educational effect in pharmacology is expected.

BACKGROUND: The claudins are a family of transmembrane proteins associated with tight junctions and they are critical for maintaining cell-to-cell adhesion in sheets of epithelial cells. However, their role in the progression of cancer remains largely unexplored. The aims of this study were to evaluate the expression patterns of claudin-1 and -4 in benign lesions and invasive ductal carcinomas (IDC) of the breast, and relationships between the expression of these markers and the clinicopathological characteristics in IDC patients. METHODS: We examined the claudin-1 and -4 protein expressions by performing immunohistochemical stainings in 54 benign lesions and 120 IDCs via the tissue microarray method. We evaluated the correlation between the expression of these markers and the clinicopathological characteristics of IDC. RESULTS: The expressions of claudin-1 (p=0.099) and -4 (p=0.000) were up-regulated in IDCs as compared with benign lesions. The claudin-1 expression correlated with the loss of estrogen receptor (p=0.036) and progesterone receptor (p=0.011). The claudin-4 expression correlated with lymph node metastasis (p=0.043), the nuclear grade (p=0.030), the histologic grade (p=0.007), and the loss of estrogen receptor (p=0.001) and progesterone receptor (p= 0.029). CONCLUSIONS: These results suggest that claudin-1 and -4 may play a significant role in the carcinogenesis of IDC of the breast and these may represent novel markers for this disease.

In this study, we developed an educational content for learning the nervous system of human body which is one of the educational topics in basic nursing science. We also developed and operated Homepage program based on that content. This program was designed for providing learning contents consistently to the nursing students and nurses regardless of the education system or location. The strengths of the present study are as follows: 1) Learning contents of the study were systematically developed by the methodological research method, 2) The students who could access the program would be broadened because the program is internet-based, 3) The students and teachers could have effective communication via a visiting list or bulletin board. In the future, it is expected that similar internet based learning programs are developed continuously in many other areas in the basic nursing science as well as the nervous system of human body.

Background: This is an observational study to analyze an emergency department (ED) utilization pattern of coronavirus disease 2019 (COVID-19) vaccinated in-hospital healthcare workers (HCWs). Methods: We included 4,703 HCWs who were administered the first dose of the COVID-19 vaccine between March 4 and April 2, 2021, in a tertiary hospital in Korea where fast-track and post-vaccination cohort zone (PVCZ) were introduced in ED. We analyzed data of participants' age, sex, occupation, date and type of vaccination, and their clinical information using SPSS v25.0. Results: The sample comprised HCWs, who received either the ChAdOx1 (n = 4,458) or the BNT162B2 (n = 245) vaccines; most participants were female (73.5%), and 81.1% were under 50 years old. Further, 153 (3.3%) visited the ED and reported experiencing fever (66.9%) and myalgia (56.1%). Additionally, 91(59.5%) of them were in their 20s, and 106 (67.5%) were assigned to the PVCZ. Lastly, 107 (68.2%) of the patients received parenteral management.No patient required hospitalization. Conclusion In conclusion, vaccinated HCWs who visited the ED with adverse events had a high incidence of fever and a low likelihood of developing serious illnesses. As the COVID-19 vaccination program for Korean citizens continues to expand, strategies to minimize unnecessary ED overcrowding should be put into effect.

PURPOSE: For the atypical cases of fine needle aspiration (FNA) cytology of thyroid nodules, ultrasonographic findings are a primary guideline for the surgical treatment. However, they have the intrinsic risk of overtreatment, as well. In this study we examined whether the Bethesda system could provide a real effect on the diagnostic rate of atypical cytology, and thereby reduce the number of cases diagnosed as atypical from FNA cytology. METHODS: We reviewed 166 cases diagnosed as atypical by FNA cytology at this institute between the years 2005 to 2010. We classified these cases on the basis of ultrasonographic and cytological findings and compared them with the histological results. RESULTS: Ultrasonographically, findings suspicious for malignancy and indeterminate were associated with 83.7% and 47.2% of malignancy rates, respectively. Cytopathologically, the malignancy rates varied according to the main cytological features and the highest malignancy rate was 77.3%. Based on the Bethesda system, 39.2% of the cases diagnosed as atypical could be grouped into the category of suspicious for malignancy and yielded a malignancy rate of 76.9%. CONCLUSION: Although ultrasonography provides an excellent guideline for the surgical treatment of atypical cases, it also showed considerable risk of overtreatment. The Bethesda system did not offer definitive effects on the rate of atypical cytology, but this system seemed to provide stricter boundaries for the atypical cytology and to aid in reducing the rates thereof. This in turn may permit that more limited cases are allotted to ultrasonographic decision making.

In this study the effect of insulin and aminoguanidine on the expression of iNOS and the development of insulitis in the multiple low dose streptozotocin (SZ) induced diabetic (LDSD) mice was evaluated. Eighty mice (Charles-River CD-1 mice) were divided into four groups. Group I received SZ for five days. Group II received SZ for five days and was followed by insulin treatment. Group III received SZ for five days and was followed by aminoguanidine treatment. Group IV was normal control group. The blood glucose level and body weight were measured weekly. On the 35th day, pancreat ic sections were observed to evaluate the frequency and the severity of insulitis in addition to the immunohistochemical expression of iNOS in the pancreatic islets. Blood glucose levels of group IV were significantly lower than other experimental groups on the 21st, 28th, and 35th day. The difference in blood glucose levels was not statistically significant. Incidence of the insulitis was lower in group II than in groups I and III. The severity of insulitis correlated with the increase in blood glucose level only in group II. The expression of iNOS was more pronounced in group I than in groups II and III. Aminoguanidine did not inhibit development of the insulitis but decreased expression of iNOS in the pancreatic islets. Therefore it is speculated that iNOS production is one of the factors and other pathogenetic mechanisms might be involved in the development of insulitis.

BACKGROUND: The p73 is a recently identified homologue of the tumor suppressor gene, p53, and it has been found to induce apoptosis and inhibit cell proliferation. However, its role in the development of tumors is unclear. This study examined the expression of p73 in patients with non-small cell lung carcinomas (NSCLCs) to determine its clinical significance and association with the expressions of p53, pRb, and mdm2. METHODS: A total of 183 NSCLCs were analyzed immunohistochemically using a tissue microarray. RESULTS: The p73 protein was expressed in the cell nuclei in 156 (85.2%) out of the 183 cases. There was no correlation between the p73 expression and the clinicopathological variables. However, there was a correlation between the p73 expression and the mdm2 and pRb expressions. Multivariate Cox survival analysis identified tumor size and lymph node metastasis to be independent prognostic factors, but the p73 expression was not found to be associated with the patients' survival. CONCLUSIONS: p73 is commonly expressed in NSCLC and it might, in conjunction with pRb and mdm2, be involved in the development of these tumors.
