PURPOSE: This study was a systematic review to evaluate the effects of aromatherapy on menopausal symptoms, perceived stress and depression in middle aged-women. METHODS: Eight databases were searched from their inception September 8, 2015. Two reviewers independently performed the selection of the studies, data abstraction and validations. The risk of bias was assessed using Cochrane criteria. For analysis of the data, a meta-analysis of the studies was performed. RESULTS: From the electronic databases, 73 articles were selected, and 19 removed due to duplication. After two reviewers read the abstracts of 54 studies, 34 studies were selected. Complete papers for 34 original articles were read and, 12 studies which met selection criteria were reviewed and the effects of aromatherapy on menopausal symptoms, stress and depression analyzed using meta-analysis with RevMan. In the 2 studies which included Randomized Controlled Trials testing of aromatherapy on menopausal symptoms and comparison of control and placebo groups were done. Aromatherapy massage was favorably effective in reducing the menopausal symptoms compared to the control group (n=118, MD=-6.33; 95% CI -11.51 to -1.15), and compared to the placebo group (n=117, MD=-4.14; 95% CI -7.63 to -0.64). Also aromatherapy was effective in reducing stress (n=72, SMD=-0.64; 95% CI -1.12 to -0.17) and depression (n=158, MD=-5.63; 95% CI -10.04 to -1.22). CONCLUSION: There is limited evidence suggesting that aromatherapy for middle-aged women may be effective in controlling menopausal symptoms, perceived stress and depression.

Changes in plasma level of arginine vasopressin (AVP), arterial pressure, and urine flow were studied before, during and after cardiopulmonary bypass (CPB) in 11 patients with congenital heart disease. Anesthesia was induced with thiopental sodium (3-5 mg/kg) and was maintained with enflurane (1.0-1.5%), 50% N2O in O2 and morphine (0.5 mg/kg). Concentration of plasma AVP increased slightly from 3.8 +/- 1.5 pg/ml after induction and increased 3-fold after sternotomy. Plasma AVP level increased to 132 +/- 26 pg/ml and 218 +/- 54 pg/ml after 5 and 60 min on CPB, respectively. When the circulation returned to normal, plasma AVP level decreased gradually but was still significantly higher at 24 hr (13.4 +/- 2.5 pg/ml). Marked osmolar diuresis was induced with mannitol in the priming solution used during the CPB: increases in urine flow, Na excretion and osmolar clearance. Possible mechanisms of marked increase in AVP release and differences of AVP responses during CPB reported by other investigators are discussed.

A 78-year-old woman was referred to Chonbuk National University Dental Hospital complaining of facial palsy and palpable mass on the right parotid gland area. Clinical examination showed non-specific findings of the intraoral region, but showed asymmetrical facial appearance. Panoramic view showed a large amorphous calcified mass on the posterior to the mandibular ramus and thin cortical plate of the posterior ramus. Sialogram showed constriction of the main duct and no further filling of striated, intercalated ducts and parenchymal areas. CT scans demonstrated an irregular, infiltrating mass with slight enhancement in the right parotid gland. The mass showed necrotic areas and calcifications. Bone scan showed marked accumulation of (99m)Tc-MDP on the right posterior maxilla. Microscopic findings demonstrated the minimal morphologic alterations and rare mitotic figures within tumor cells, and diagnosed as adenocarcinoma (NOS, Grade II). This report could be aid in the diagnosis of calcified lesions of the salivary gland.

BACKGROUND: The differential diagnosis of Kaposi sarcoma includes many disease that range from benign disease to malignant tumors. However, little information is available about the immunohistochemical characteristics of Kaposi sarcoma. METHODS: The expressions of 13 various proteins (HHV-8 LNA-1, Ki-67, bcl-2, p53, CD31, CD34, factor VIII, D2-40, vimentin, SMA, S-100, EMA, and c-kit) were evaluated immunohistochemically in 49 vascular tumors including 16 Kaposi sarcomas, 8 angiosarcomas, 2 hemangioendotheliomas, and 23 benign vascular tumors with using the tissue array method. RESULTS: All 16 cases of Kaposi sarcoma showed nuclear staining for HHV-8 LNA-1, whereas all the cases of angiosarcoma and benign vascular lesions were negative for HHV-8 LNA-1 (p<0.001). All Kaposi sarcoma were positive for D2-40, which is a marker of lymphatic differentiation, but 25% of the benign vascular lesions and 30.4% of the angiosarcoma were positive for D2-40 (p<0.001). The mean proliferation index as assessed by Ki-67 immunostaining revealed no difference between the benign and malignant vascular lesions (p>0.05). No Kaposi sarcoma showed a bcl-2 expression, but 62.5% of the angiosarcomas and 21.7% of the benign vascular tumors had bcl-2 expressions (p=0.005). CONCLUSIONS: Immunohistochemical detection of HHV-8 LNA-1 and D2-40 are useful tools to differentiate Kaposi sarcoma from other vascular tumors.

This study describes the purification and characterization of type II restriction endonuclease of Helicobacter pylori in order to understand the DNA restriction and modification of H. pylori. H. pylori cell extract was subjected to polyethyleneimine treatment, salt precipitation, heparine-sepharose column chromatography, and fast protein liquid chromatography (FPLC) using Resource Q column and Mono Q column to purify the type II restriction endonuclease. Hpy51-I was characterized to recognize the sequneces 5`-GT(G/C)AC-3`, yielding 5-base 5` protruding ends. The restriction sequence was identical to that of Tsp 45 I. The enzyme exhibited its maximal activity in the presence of 10-20 mM LaCl, but was inhibited completely in the presence of more than 80 mM NaCl. The enzyme showed its maximal activity in the presence of 1-10 mM MgC1(2). The optimal pH and temperature for enzyme activity was pH 9.0 and 37 degrees C, respectively. MnC1(2) could not substitute for MgC1(2) in reaction mixture. And addition of j3-mercaptoethanol and bovine serum albumin in reaction mixture led to loss of enzyme activity of Hpy51-I. The whole cell extract of H. pylori strain 51 was confirmed to carry the enzyme activity for methylation of Hpy51-I-recognised sequence. Hpy51-I digested genomic DNAs of enteric bacteria to less than I kb while it could not cut the genomic DNAs of H. pylori isolates. In this study, the type II restriction enzyme (Hpy51-I) of H. pylori was identified and characterized its biochemical properties, demonstrating that Hpy51-I might be one of the barriers for preventing the introduction of foreign DNAs into H. pylori.

Helicobacter pylori is a causative agent of type B gastritis and plays a central role in the pathogenesis of gastroduodenal ulcer and gastric cancer. To elucidate the host-parasite relationship of the H. pylori infection on the basis of molecular biology, we tried to evaluate the genomic diversity of H. pylori. An ordered overlapping bacterial artificial chromosome (BAC) library of a Korean isolate, H, pylori 51 was constructed to set up a genomic map. A circular physical map was constructed by aligning ApaI, Notl and SfiI-digested chromosomal DNA. When the physical map of H. pylori 51 was compared to that of unrelated strain, H. pylori 26695, completely different restriction patterns were shown. Fifteen known genes were mapped on the chromosome of H. pylori 51 and the genetic map was compared with those of strain 26695 and J99, of which the entire genomic sequences were reported. There were some variability in the gene location as well as gene order among three strains. For further analysis on the genomic diversity of H. pylori, when comparing the genomic structure of 150 H. pylori Korean isolates with one another, genomic macrodiversity of H. pylori was characterized by several features: whether or not susceptible to restriction digestion of the chromsome, variation in chromosomal restriction fingerprint and/or high frequency of gene rearrangement. We also examined the extent of allelic variation in nucleotide or deduced amino acid sequences at the individual gene level. fucT, cagA and vacA were confirmed to carry regions of high variation in nucleotide sequence among strains. The plasticity zone and strain-specific genes of H. pylori 51 were analyzed and compared with the former two genomic sequences. It should be noted that the H. pylori 51-specific sequences were dispersed on the chromosome, not congregated in the plasticity zone unlike J99- or 26695-specific genes, suggesting the high frequency of gene rearrangement in H. pylori genome. The genomc of H. pylori 51 shows differences in the overall genomic organization, gene order, and even in the nucleotide sequences among the H. pylori strains, which are far greater than the differences reported on the genomic. diversity of H. pylori.

Two-dimensional gel electrophoresis (2-DE) is an essential tool of proteomics to analyse the entire set of proteins of an organism and its variation between organisms. Helicobacter pylori was tried to identify differences between strains. As the first step, whole H. pylori was lysed using high concentration urea contained lysis buffer (9.5 M Urea, 4% CHAPS, 35 mM Tris, 65 mM DTT, 0.01% SDS and 0.5% Ampholite (Bio-Rad, pH 3-10)). The extract (10 mug) was rehydrated to commercially available immobilised pH gradient (IPG) strips, then the proteins were separated according to their charges as the first dimensional separation. The IPG strips were placed on Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) to separate according to molecular mass of the proteins as the second dimension. The separated protein spots were visualised by silver staining in order to compare different expression of proteins between strains. Approximately 120 spots were identified in each mini-protein electrophoresised gel, furthermore about 65 to 75 spots were regarded as identical proteins in terms of pI value and molecular weight between strains used. In addition, distinct differences were found between strains, such as 219-1, Y7 and Y14, CH150. Two representative strains were examined using strips which had pH range from 4 to 7. This strips showed a number of isoforms which were considered large spots on pH range 3-10. Furthermore, the rest of spots on pH 4-7 IPG strips appeared very distinctive compared to broad range IPG strips. 2-DE seems to be an excellent tool for analysing and identifying variations between H. pylori strains.

Objective: Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one’s physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. Methods: Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. Results: Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. Conclusion This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.
