The purpose of this study was to investigate the immunohistochemical reaction of calcitonin-gene-related peptide (CGRP) and type II collagen and also morphological changes of cartilage implants and cultured chondrocytes isolated from the articular and costal cartilages. The chondrocytes were isolated from the head of the femur and the 11th costal cartilage of the 6 months old rabbits. De novo implants were prepared from the chondrocytes cultured on the perichondrium by culturing isolated articular chondrocytes. Cultured chondrocytes and implants were evaluated by immunohistochemical staining of CGRP and type II collagen and electron microscopy. Articular chondrocytes maintained the typical phenotype in the 1st and 2nd subcultures, but the costal chondrocytes were transformed into fibroblast-like cells. The articular chondrocytes cultured on the perichondrium were more flattened and formed the cartilage. Most chondrocytes were no loss of type II collagen immunostaining by culturing. Implants replaced by the cultured articular chondrocytes were generally increased CGRP and decreased type II collagen immunoreaction. Electron microscopically the cultured articular chondrocytes had a large euchromatic nucleus, a few granules, and abundant vesicles. During culture, the nucleus became atropy and the cytoplasm contained many large vacuoles. The chondrocytes cultured on the perichondrium showed a lot of segmented rough endoplasmic reticulum and fine short microvilli. During culture, articular chondrocytes maintained typical phenotype and type II collagen reaction. The cultured articular chondrocytes had some organelles and euchromatic nucleus with prominent nucleolus. The chondrocytes cultured on the perichondrium showed active secretion of the matrix with small vesicles and well developed endoplasmic reticulum. The implanted articular chondrocytes showed the decrease of their organelles after secretion of the marix and became increased CGRP and decreased type II collagen immunoreaction.

Ethical problems in an emergency department (ED) are much more common than is usually recognized. But these difficult ethical dilemmas have not been dealt with by general medical ethicists. Most medical ethics guidelines tend to concentrate on chronic or at least relatively stable situations rather than on the acute, episodic cases that are typical in the ED. most ethical problems such as abortion, euthanasia, and professionalism can be solved after reflection and deliberation, and after a process of communication that reveals the values and interests of the patient or the patient's family. In contrast, when health care professionals in the ED recognize ethical problems, they often don't have enough time for an ethical consultation such as a Hospital Ethics Committee. Ethical principles such as autonomy, beneficence, nonmaleficence, and justice need to be applied to the unique setting of emergency medicine. Hence, it is necessary to develop ethics guidelines in emergency medicine and ethics education for health care professionals in emergency departments. At first, we collected cases involving ethical problems and reviewed the ethical and legal aspects of those cases. In this article, we summarize the ethical issues in emergency medicine, deal with actions in emergency medical services, and also consider the relationships between ethical issues and act on emergency medical services. We want to present the important factors that should be considered in ethical decision making within an emergency medicine department including patient decision making capacity, legal custody, and ethical principles.

The fine structure of cells in the trigeminal mesencephalic (Me5) nucleus in the rat was studied by transmission electron microscopy. This nucleus located in the mid-brain and the rostral portion of the pons, most neurons in the caudal part of Me5 nucleus were sufficiently large (40~50micrometer) and appeared as round-shaped unipolar cells. The Me5 neurons had a large, round, centrally located nucleus, and their cytoplasm contained numerous mitochondria, dense granular endoplasmic reticulum, abundant Golgi apparatus, groups of free ribosomes, some heterogeneous particles and neurofilaments. Cell surfaces were studded irregularly with small spinouts processes, and they contained a few fine irregularly arranged neurofilaments and some granular endoplasmic reticulum. Boutons contacting the soma of Me5 neurons were defined as axosomatic synapses and bostons contacting dendrites located between the Me5 neurons were defined as axodendritic synapses. Based on differences in bouton and vesicle morphology, the four synaptic bouton types were identified. 1. Asymmetrical as well as symmetrical synapses with small round vesicles. 2. Asymmetrical synapses with pleomorphic admixture contained predominantlyspherical vesicles. 3. Symmetrical synapses with pleomorphic vesicles of flattened, spherical and dense-core vesicles. 4. Asymmetrical as well as symmetrical synapses with heterogeneous and large dense-core vesicles. Synaptic boutons containing round vesicles and large dense-core vesicles were most frequently observed.

Lipedema is a chronic disease of lipid metabolism that results in the symmetrical impairment of fatty tissue distribution and storage combined with the hyperplasia of individual fat cells. Lipedema occurs almost exclusively in women and is usually associated with a family history and characteristic features. It can be diagnosed based on clinical history and physical examination. Lipedema is usually symmetrical, but spares the feet, is often painful to palpation, and is negative for Stemmer's sign. Additionally, lipedema patients can present with microangiopathies and lipomas. The well-known therapies for lipedema include complex decongestive therapy, pneumatic compression, and diet modifications. However, whether these treatments help reduce swelling is debatable. We encountered a case of lipedema that was initially misdiagnosed as lymphedema. The patient's clinical features and history were different from those typical of lymphedema, prompting a diagnosis of lipedema and she was treated with a complex decongestive therapy program.

Systemic lupus erythematosus is a multisystemic autoimmune disease in which the kidneys are frequently involved. Clinical diagnosis of SLE is based on the criteria of American Rheumatism Association (ARA). A few cases who were classified as SLE by the ARA criteria but were antinuclear antibody (ANA)-negative have been reported. It was reported that critical factor in ANA positivity is the choice of substrate. It is generally accepted that the cultured cell of human origin, especially HEP-2 cell, is better than tissue section or animal cells. Thus, the ANA test is negative only in approximately 2M of SLE patients when human tissue culture cells are used as substrate. We report a 25-year-old man admitted to our hospital because of generalized edema. He was found to have active lupus nephritis(WHO class IV), photosensitivity and pancytopenia. The result of FANA test which used HEP-2 cell as substrate was repeatedly negative, but anti-ds DNA and anti-Ro antibody were positive.

OBJECTIVES: Protein-calorie malnutrition has been shown to be prevalent among patients on chronic dialysis, And assessment of nutritional status of continuous ambulatory peritoneal dialysis(CAPD) patients has assumed greater importance because of the association of protein-calorie malnutrition with increasing morbidity and mortality. So we observed the incidence and clinical effect of protein-calorie malnutrition, and we compared the indices of nutrition with dialysis adequacy utilizing urea kinetic modeling and cretinine clearance in CAPD patients. METHODS: We performed a cross-sectional study in which eight parameters, based on anthropometry, blood chemistry and subjective symptoms, were scored according to the degree of abnormalities in 82CAPD patients. A malnutrition index was derived from these scores. We also performed comparative analysis to identify significant correlations of the indices of urea kinetic modeling and creatinine clearance with the other parameters of nutritional status. RESULTS: The malnutrition index classified 47(57%) patients as normal, 30(37%) intermediately malnourished, and 5(6%) as severely malnourished. Malnutrition index showed a significant correlation with the body mass index(BMI), triceps skinfold thickness(TSF), mid-arm circumference(MAC), mid-arm muscle area (MAMA), duration of CAPD, subjective symptoms, serum albumin, transferrin, cholesterol, and triglyceride. The malnutrition index also showed a significant correlation with residual renal function(RRF), and standardized creatinine clearance(SCCr). The TWR-Kt/V(total Kt/Vurea per week with consideration of residual renal urea clearance) was significantly lower in the severely malnourished group than in the normal group. Serum alkaline phosphatase and BUN levels were higher in the severely malnourished group than in the normal and inter-mediate groups. CONCLUSION: In assessing the nutrition status of CAPD patients, body weight, TSF, MAC, MAMA, subjective symptoms, serum albumin, transferrin, cholesterol, triglyceride, urea nitrogen, and alkaline phosphatase were considered useful parameters. There was a trend of increased BUN and decreased TWR-Kt/V in severely malnourished patients, and the value of SCCr was significantly lower in malnourished patients. However, no meaningful relationships between TW-Kt/V and malnutrition index or between NPCR(normalized protein catabolic rate) and malnutrition index were found m this cross-sectional study. As the number of patients with longer duration of CAPD or negligible RRF has increased in the malnourished patients, regular monitoring of these parameters, especially TWR-Kt/V and SCCr, may be helpful to assess dialysis adequacy to keep good nutritional status of each CAPD patient.

Acute suppurative thyroiditis(AST) and thyroid abscess are uncommon in children. The remaining pyriform sinus tract with fistula is well known underlying abnormality of AST in pediatric patients. AST or thyroid abscess in children can be caused by infection through pyriform sinus fistulae which usually originate from the tip of the left pyriform sinus. The left-sided predominance of involvement and frequent recurrence are characteristic findings. We present a case history that include a left sided thyroid lesion of a 5-year-old girl and radiologic evidence of pyriform sinus fistula. The pus culture revealed the bacterial etiology as Staphylococcus epidermidis. Our discussion focused on the etiology and the management of AST and thyroid abscess in children.
