The fibrillar coat of Candida albicans is of interest as its significance in antigenicity, antiphagocytosis, and adherence to host tissues. The partial biochemical properties and ultrastructure of fibrillar coat induced by rabbit sera were examined. The induced fibrillar layer was destroyed by treatments of lyticase, proteinase K and dithiothreitol. The total protein concentration of fibrillar cell wall lysate was higher than that of non-fibrillar cell wall lysate, but the total sugar concentration was similar. On SDS-PAGE analysis, the protein profiles between in fibrillar cells and in non-fibrillar cells were shown to be different. In fibrillar cells, the major bands of cell wall lysate were 83, 66, 54, 47, 33, and 26 kDa in dithiothreitol-treated lysate. The proteins of 26 and 19 kDa were predominant in lyticase-treated lysate. Although the fibrillar thickness and protein amount of cell wall lysate were increased in according to the incubation time, the protein profiles did not changed. These results suggest that the proteins of 83, 66, 54, 47, 33, 26, and 19 kDa may be major constituents of fibrillar coat in C. albicans.

OBJECTIVES: This research aimed to understand the popularity of topics in the field of women's health through analysis of online news articles which were chronologically classified and examined to determine how women's health and diseases had changed over time. METHODS: Women's health and disease news articles were collated from a popular news website between 1993 to 2015 and preprocessed using gynecological medical terminology, Korean words and nouns (excluding general nouns not related to women's healthcare topics). The resultant articles (N = 7,710) were analyzed using the Latent Dirichlet Allocation algorithm and major topics were extracted. Topic trends were analyzed by year and period for women's health. RESULTS: It was observed that most of the women's health articles were focused on “Healthcare”, and 9 other topics were identified that represented a relatively small proportion in 1993–2000. In 2001–2005, most of the articles were focused on “Medical Services” and “Dietary Supplements” with some specific topics that peaked people's interest, as compared to those focused on “Healthcare” in the 1990s. It was also observed that differences in the proportion of each topic was small after 2011. CONCLUSION: Changes in topics related to women's disease were not clearly distinguished in the 1990s but this changed from 2001where articles related to “women disease” appeared as articles on the topics of various diseases.

PURPOSE: To assess the usefulness of CT scanning in the differentiation of stage T3a from T2 in renal cell carcinoma. MATERIALS AND METHODS: Among patients with pathologically proven renal cell carcinoma, 114 at stages T2 and T3a were divided into three groups, as follows: intact capsule (T2) n=40, capsular involvement (T2) n=38, and capsular penetration (T3a) n=36. By referring to contrast-enhanced CT scans, we retrospectively compared the groups in terms of tumor margin, the frequency with which a tumor bulged more than 3 cm beyond the renal contour, the presence or absence of peritumoral collateral vessels, thickening of Gerota 's fascia, and perinephric strands. RESULTS: An irregular margin was more common in the capsular penetration group than in the other two groups (p<0.05). With regard to frequency of tumor bulging, the presence of peritumoral collateral vessels, thickening of Gerota 's fascia, and perinephric strands, these characteristics were more frequently noted in the capsular penetration group (T3a) and capsular involvement group (T2) (p<0.05) than in the intact capsule group. The difference between the capsular penetration group (T3a) and the capsular involvement group (T2) was not significant, however (p>0.05). CONCLUSION: In determining the tumor stage of renal cell carcinoma, CT is not helpful in differentiating between a tumor with capsular penetration (T3a) and one with capsular invasion (T2), though differentiation of the T3a stage from the T2 stage, without capsular invasion, is reliable. When a tumor has an irregular margin, however, the possibility that it is at stage T3a should be considered.

Phenobarbital is a long-acting barbiturate causing generalized depression of neuronal activity in the brain. Its effect is primarily achieved through enhanced GABA-mediated synaptic inhibition. Its use as an antiepileptic agent was first described in 1912. Before the introduction of phenytoin, phenobarbital is used as sedative-hypnotics. It is used for the treatment of epilepsy and status epilepticus. All barbiturates, including phenobarbital, have a high potential far abuse. They were frequently used for suicide attempts in the past, but they have in large part been replaced by benzodiazepines. the onset of symptoms depends on the drug and the route of administration. Mild to moderate barbiturate intoxication resembles ethanol inebriation with slurred speech, ataxia, and lethargy. Severe acute barbiturate intoxication is life threatening. Early deaths are generally cardiovascular-related. Hypotension, shock, pulmonary edema, and cardiac arrest that occurs with large doses are caused by depression of central sympathetic tone and as well as by direct depression of cardiac contractility. The potentially fatal oral dose of phenobarbital is 6-l0g. We describe an 23-year-old woman with pulmonary edema and cardiac arrest after ingestion of 18 grams of phenobarbital. She was completely recovered by successful cardiopulmonary resuscitation and hemoperfusion. We report a case with literature review.

Isoniazid(Isonicotinic acid hydrazide) is an antimicrobial drug used since 1952 as a fast line agent for the prophylaxis and treatment of tuberculosis. Isoniazid is well known for problems in population having a high prevalence of isoniazid use for prophylaxis or treatment of tuberculosis. But intentional or accidental isoniazid overdose is uncommon. The ingestion of toxic amounts of isoniazid causes recurrent seizures, profound metabolic acidosis, coma and even death. In adults, toxicity can occur with the acute ingestion of as little as 1.5g of isoniazid. Doses larder than 30mg per kg often produce seizures. When ingested in amounts of 80-150mg per kg or more, isoniazid can be rapid fatal. 40-year-old woman having previous pulmonary tuberculosis ingested 7 gram of isoniazid(140mg/kg) to attempt suicide approximately 30 minutes prior to visit to our emergency medical center. She had recurrent generalized tonicclonic seizures and metabolic acidosis. We report one patient treated with pyridoxine, which was equivalent to the amount of isoniazid ingested and administered as a intravenous dose and oral dose.

BACKGROUND: Flood is the most common natural disaster in our country. Lots of victims occurred during the period of flood in the northern territory of Kyoungkido on August 5, 1998. We tried to describe the characteristics of the flood-related injury and illness, management and medical requirements. METHODS: We interviewed the patients admitted to 8 hospitals in Ujungbu and reviewed medical records from aug 5 to Aug 14, 1998. RESULTS: There were total 102 patients, male were 52%and women were 48% Most of patients were between 30's and 60's. Most of them were minor, and less than 3%of them needed critical care. The diagnosis were laceration(39.2%, contusion(22.5%, fracture(13.7%, infectious disease(7.8%, ligament rupture(7.8%, aggravation of chronic illness(5.9%, dermatitis(2.0% and traumatic hyphema(1.0%. The laceration occurred in the foot(37.9%, lower leg(27.0%, thigh(16.2%, hand(10.8% and head(8.1%. The location of ligament injury were achilless tendon(62.5%, hand(25% and knee(12.5%. The 67.5%of flood-related laceration patients progressed cellulitis, especially in sutured wound and a typical tetanic patient was developed. Of hospitalized patients, 2 patients showed evidence of post-traumatic stress disorder(PTSD). CONCLUSION: During flood, civils have better to be educated about prevention of injury, such as wearing of shoes and clothes. Although laceration was minor, lacerated wounds should be thoroughly irrigated, debrided the margin and considered delayed closure, tetanus immunization. Reportedly, there is an increased prevalance of PTSD and depression after disasters. Therefore mental health care will be required in the future.

Previous studies have shown that plant-based vegetarian diets, which typically contain a variety of antioxidants and dietary fiber, help reduce the risk of heart disease, diabetes, obesity, and cancer. However, some studies have reported that vegetarian diets can lead to deficiencies in protein and trace minerals compared to non-vegetarian diets. This study was conducted to compare anthropometric measurements, blood parameters, dietary intake, and hair mineral status in long-term vegetarians (MV; moderate vegan, LV; lacto-ovo vegetarian) and non-vegetarians (NV). Thirty MV (12 males, 18 females; mean age, 50.58 +/- 5.05 years), 15 LV (11 males, four females; mean age, 49.45 +/- 4.97 years), and 30 NV (15 males, 15 females; mean age, 48.90 +/- 3.62 years) participated. No significant differences were observed for age, height, weight, or body mass index, but body fat was significant lower in MV and LV males than that in NV males. White blood cell counts of MV, LV, and NV male subjects were significantly different. Dietary intake data showed that plant protein and plant iron intake were significantly higher in MV and LV than those in NV. Animal protein, animal fat, and animal iron intake were significantly higher in NV than those in MV and LV. A hair mineral analysis showed that calcium and iron were higher in the hair of MV and LV than those in NV. Zinc concentration in hair was not significantly different among the groups. The results suggest that vegetarian diets are adequate to sustain mineral status to at least the same degree as that of non-vegetarian diets.

The aim of this study was to analyze the relationship between serum pro-hepcidin concentration and the anemia profiles of rheumatoid arthritis (RA) and to estimate the pro-hepcidin could reflect the disease activity of RA. RA disease activities were measured using Disease Activity Score 28 (DAS28), tender/swollen joint counts, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Anemia profiles such as hemoglobin, iron, total iron binding capacity (TIBC), ferritin, and transferrin levels were measured. Serum concentration of pro-hepcidin, the prohormone of hepcidin, was measured using enzyme-linked immunosorbent assay (ELISA). Mean concentration of serum pro-hepcidin was 237.6+/-67.9 ng/mL in 40 RA patients. The pro-hepcidin concentration was correlated with rheumatoid factor, CRP, ESR, and DAS28. There was a significant correlation between pro-hepcidin with tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6. The pro-hepcidin concentration was significantly higher in the patients with active RA (DAS28>5.1) than those with inactive to moderate RA (DAS28< or =5.1). However, the pro-hepcidin concentration did not correlate with the anemia profiles except hemoglobin level. There was no difference of pro-hepcidin concentration between the patients with anemia of chronic disease and those without. In conclusion, serum concentration of pro-hepcidin reflects the disease activity, regardless of the anemia states in RA patients, thus it may be another potential marker for disease activity of RA.

Symptomatic hepatic cysts are infrequently seen. A 82-year-old woman was admitted because of growing abdominal mass and pain. On admission, the mass was palpated on right upper quadrant of the abdomen. Ultrasonography and computed tomography disclosed a huge cystic lesion of the liver. It measured 22.5 x 19.0 x 18.0 cm and had a thick wall that was irregular. Because of the patient's symptoms and the radiologic findings, the decision was made to aspirate the cyst percutaneously under fluoroscopic guidance. Percutaneous drainage yielded approximately 3300 cc of yellow brownish fluid. A cytologic evaluation of the fluid was negative for malignant cells, and a fluid analysis was described as predominantly inflammatory in nature. Cultures revealed a growth of Klebsiella oxytoca. After drainage of the cystic fluid, we instilled contrast medium. No communication between the cyst and bile ducts was seen. Seven days later, the patient was discharged. Four months after treatment, no reaccumulated fluid was observed by ultrasonography. Ten months after treatment, the patient is healthy without abdominal discomfort. We report a case of the infected huge hepatic cyst successfully treated with fluoroscopic-uided percutaneous drainage.
