The author reviewed references of the articles published in the Journal of Korean Neurosurgical Society(J Kor Neurosurg Soc), which is the only official journal of the Korean Neurosurgical Society. The number and descriptive methods of the references, and the instructions to contributors were studied. Some faults in the articles and the instructions were pointed out to improve the journal. Overall, 555 articles(30.0%) referenced articles published in the J Kor Neurosurg Soc. The number of referenced articles publishted in the journal was 1,223. The ratio of referenced articles published in the J Kor Neurosurg Soc to the total number of references was 3.0%. The number of the articles referencing articles published in the J Kor Neurosurg Soc was one in Volume 2, but it became 64 in Volume 17. Such tendency to increase seems to be continued. However, descriptive methods of references and the abbreviations of the journals were extremely variable. For the consistant reference, some correction of the instructions were proposed.
Abbreviations

Currently we are living in an era of abbreviations. In almost every field of modern societies including government, military, hi-tech areas, and especially Internet communications, linguistic shortcuts have ever grown fast and furiously. Abbreviated words may save time and space and energy, however, may cause confusion and errors. These shortened forms of words or phrases include acronyms, clippings, contractions, blends, symbols and some slangs. Traditionally healthcare fields using rather a long terminology have utilized abbreviations and symbols in repeated and busy practices as well as in medical writings. Here how to make and use abbreviations especially in the field of medicine is reviewed and discussed. In order to coin a new abbreviation in a manuscript, it is advisable to follow certain principles to make an acceptable shortened form.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is associated with increased risk of malignant ventricular arrhythmias. Cardiac electrical inhomogeneity may be the leading cause of the increased arrhythmic risk in patients with T2DM. The peak and the end of the T wave (Tp-e) interval and associated Tp-e/QT ratio are promising measures of ventricular repolarization indicating transmural dispersion of repolarization. The aim of this study was to assess ventricular repolarization in patients with T2DM by using Tp-e interval, Tp-e/QT ratio and Tp-e/corrected QT interval (QTc) ratio. METHODS: Forty-three patients with T2DM and 43 healthy control subjects, matched by gender and age, were studied. All participants underwent electrocardiography (ECG) recording. PR, RR and QT intervals represents the ECG intervals. These are not abbreviations. In all literature these ECG intervals are written like in this text. Tp-e intervals were measured from 12-lead ECG. Rate QTc was calculated by using the Bazett's formula. Tp-e/QT ratio and Tp-e/QTc ratio were also calculated. RESULTS: Mean Tp-e interval was significantly prolonged in patients with T2DM compared to controls (79.4±10.3, 66.4±8.1 ms, respectively; P<0.001). We also found significantly higher values of Tp-e/QT ratio and Tp-e/QTc ratio in patients with diabetes than controls (0.21±0.03, 0.17±0.02 and 0.19±0.02, 0.16±0.02, respectively; P<0.001). There was no difference in terms of the other ECG parameters between the groups. CONCLUSION: Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio were prolonged in patients with T2DM. We concluded that T2DM leads to augmentation of transmural dispersion of repolarization suggesting increased risk for ventricular arrhythmogenesis.

Dear Author, You have used abbreviations that will need to be defined in the main paper, i.e. PIT1, PROP1 and MRI. This is just for your advice. Pituitary agenesis is an uncommon cause of panhypopituitarism. It has been proposed that breech delivery, or birth trauma, is a major factor causing pituitary agenesis. Recent studies have suggested that genetic defects in the PIT1 or PROP1 gene might be involved in the pathogenesis of pituitary agenesis. In this case we report on the diagnosis of a 33-years old female patient with-growth retardation and sexual infantilism. We diagnosed anterior pituitary hormones deficiencies, with the exception of adrenocorticotropic hormone, by a combined pituitary stimulation test. We observed pituitary agenesis using sella MRI. Involvement of the PIT1 or PROP1 genes in this case remains to be determined. Here we report a case of pituitary agenesis found in an adult woman together with a brief review about this disease entity.

PURPOSE: Mucinous gastric adenocarcinoma (MGC) is defined by the World Health Organization as a gastric adenocarcinoma with >50% extracellular mucin pools within the tumors. In this study, we attempted to analyze the clinicopathologic features of patients pathologically diagnosed as gastric cancer with lower than 50% tumor volume of extracellular mucin pool adenocarcinoma (LEMPC). We compared MGC versus nonmucinous gastric adenocarcinoma (NMGC). We were used in abbreviations LEMPC for NMGC including extracellular mucin pool. METHODS: Files of 995 patients with gastric cancer NMGC (n = 935), MGC (n = 20), LEMPC (n = 40) who underwent curative resection at Pusan National University Yangsan Hospital from December 2008 to December 2013 were retrospectively analyzed. All pathologic reports after curative resection and evaluated clinicopathologic features were reviewed to identify the effect of extracellular mucin pools in gastric cancer. RESULTS: Compared with the NMGC patients, the clinicopathological features of MGC patients were as follows: more frequent open surgery, larger tumor size, more advanced T stage and N stage, more positive lymph node metastasis, and perineural invasion. LEMPC patients showed similar features compared with NMGC patients. MGC and LEMPC patients showed similar clinicopathological features, except T stage and lymph node metastasis. CONCLUSION: LEMPC can be thought of as a previous step of MGC. It is reasonable to consider LEMPC patients in the diagnostic criteria of MGC, and to adequately treat.

In order to search for anti-Herpes simplex virus (HSV) type-1 agents from Korean medicinal herbs and Korean traditional prescriptions (herb complexes), we selected 80 medicinal herbs and 45 prescriptions, based on a review of the Korean traditional medicine books. Both methanol extracts and boiling-water extracts were tested by means of the MTT assay (tetrazolium based colorimetric assay). Ten of the 125 methanol extracts: CM-11, CM-18, CM-19, CM-21, CM-22, CM-39, MM-3, MM-18, MM-29, MM-73 (see explanation of nomenclature below), showed efficacy against HSV-1. Twelve of the water extracts: CW-2, CW-3-I, CW-3-II, CW-18, MW-3, MW-5 MW-6, MW-12, MW-47, MW-69, MW-73 and MW-75 were active. #3 (individual herb) and #73 (individual herb) were interesting because both water and methanol extracts were active. Especially, #3 is a part of composition of Hong-il-laksamd ngbang and Hojanghaedokt'ang which have anti-HSV-1 activitives. The SI value of MW-69 and CW-18 was relative high as 10.2+/-0.7 and 11.8+/-2.2. The cytotoxic effect on Vero cells of Panch' n-ch' ngbang, Taraxacum platycarpum H. Dahlst. and acycloguanosine was determined by MTT assay. Water extracts of Panch' ngch' ngbang (prescription) and Taraxacum platycarpum H. Dahlst. showed very weak cytotoxic effects on Vero cells at > 100 mug/ml but acycloguanosine showed strong cytotoxic effects on Vero cells at > 100 mu g/ml. As a result, #3, #73, MW-69 and CW-18 are considered as potentially useful for anti-HSV-1 agent and will be the focus of further research.

OBJECTIVES: Although acronyms and abbreviations in clinical text are used widely on a daily basis, relatively little research has focused upon word sense disambiguation (WSD) of acronyms and abbreviations in the healthcare domain. Since clinical notes have distinctive characteristics, it is unclear whether techniques effective for acronym and abbreviation WSD from biomedical literature are sufficient. METHODS: The authors discuss feature selection for automated techniques and challenges with WSD of acronyms and abbreviations in the clinical domain. RESULTS: There are significant challenges associated with the informal nature of clinical text, such as typographical errors and incomplete sentences; difficulty with insufficient clinical resources, such as clinical sense inventories; and obstacles with privacy and security for conducting research with clinical text. Although we anticipated that using sophisticated techniques, such as biomedical terminologies, semantic types, part-of-speech, and language modeling, would be needed for feature selection with automated machine learning approaches, we found instead that simple techniques, such as bag-of-words, were quite effective in many cases. Factors, such as majority sense prevalence and the degree of separateness between sense meanings, were also important considerations. CONCLUSIONS: The first lesson is that a comprehensive understanding of the unique characteristics of clinical text is important for automatic acronym and abbreviation WSD. The second lesson learned is that investigators may find that using simple approaches is an effective starting point for these tasks. Finally, similar to other WSD tasks, an understanding of baseline majority sense rates and separateness between senses is important. Further studies and practical solutions are needed to better address these issues.

BACKGROUND: The root of the plant Rosa rugosa has been reported to have an anti- hyperglycemic and anti-hyperlipidemic effect in experimental animals. But its definite anti-hyperglycemic and anti-hyperlipidemic substance has not yet been identified. In this study, we found the hydrolysable tannins of the hot water extract of the Rosa rugosa root had those effects, and named it as Rosanin. And its mode of actions were evaluated. METHODS: Three groups of streptozotocin-injected rats and two groups of buffer-injected control rats were given 10 mg/Kg/ml of Rosanin, or glibenclamide, or water by nasogastric tubes for three weeks. Blood sugar, insulin, triglyceride and GLUT4 mRNA levels were checked in the fasting state. Liver, kidney and pancreatic specimens were observed by light microscopy. RESULTS: All the water-treated, glibenclamide-treated and Rosanin-treated diabetic rats had significantly higher blood sugar levels compared to that of normal control rats (p< 0.001, p< 0.001 and p< 0.05, respectively); but Rosanin-treated diabetic rats had significantly lower blood sugar level compared to those of glibenclamide-treated and water-treated diabetic rats (p< 0.05 and p< 0.001, respectively). In the Northern blot analysis from the experimental rats' hind limb skeletal muscle RNA, all the diabetic rats showed variously decreased levels of GLUT4 mRNA compared to those of normal control rats. The water-treated diabetic group showed a 66% decline (p< 0.001); the glibenclamide-treated diabetic group led with a 2% decline; and the Rosanin-treated diabetic group revealed a 23% decline (p< 0.05). All three groups of diabetic rats had significantly lower insulin levels compared to that of normal control rats (p< 0.01), but glibenclamide-treated diabetic rats and Rosanin-treated diabetic rats had significantly higher insulin level compared to that of water-treated diabetic rats (p< 0.05, each). Furthermore, Rosanin treatment significantly decreased plasma blood triglyceride levels of streptozotocin-injected diabetic rats compared to water-treated and glibenclamide-treated, streptozotocin-injected diabetic rats (p< 0.05 and p< 0.01, respectively). The light microscopic observation of pancreatic specimens of the Rosanin-treated diabetic group showed more intact islet cells than the water-treated diabetic groups. Liver specimens of the Rosanin-treated diabetic group showed a normal appearance, but those of the water-treated diabetic groups showed severe spotty hepatic necrosis and many regenerating hepatic cells. CONCLUSION: Rosanin has an anti-hyperglycemic effect. This effect is due, in part, through the enhancement of the GLUT4 mRNA expression, the stimulation of insulin secretion in hyperglycemia, and through the preservation of pancreatic beta cells from the destructory damages of the streptozotocin. Further, it has anti-hypertriglyceridemic and hepatotoxicity-relieving effects in streptozotocin-injected diabetic animals. Abbreviations : Rosanin, the high molecular weight hydrolysable tannins of the hot water extract of the Rosa rugosa root; has an average molecular weight of about 830,000; it mainly consists of D-glucose units linked by the 1-->4 gulcoside bonds and phenolic acids, such as ellagic and gallic acid1).
