Early detection of infiltration is one of the most important tasks of nurses to minimize skin damage due to infiltration. For subjects receiving invasive intravenous treatment, the bioelectrical impedance (impedance) were measured in the frequency range of 5 to 500 kHz using bioelectrical impedance spectroscopy (BIS). After attaching electrodes at both ends of a transparent dressing mounted on the skin in which IV solution was infused into the vein, the change in impedance was measured as a function of time and frequency before and after infiltration. The experimental results are described as follows. When IV solution was properly infused into the vein, the impedance was nearly constant over time and decreased with increasing frequency. However, when infiltration occurred, the impedance decreased significantly and thereafter gradually decreased with time. In addition, impedance decreased with time for all applied frequencies. In this study, when IV solution penetrated into the surrounding skin and subcutaneous tissue by infiltration, impedance was quantitatively analyzed for as a function of time and frequency. This suggests a method for early detection of infiltration using BIS.

Backgrounds & Objectives: Many acute and chronic lung disorders with variable degrees of pulmonary inflammation and fibrosis are collectively referred to as interstitial lung diseases. Idiopathic pulmonary fibrosis (IPF) is one of several idiopathic interstitial pneumonias with the pathogenesis unclear. Astragali Radix is known to inhibit the Th2 immune response. The effects of Astragali Radix on bleomycin-induced lung fibrosis were evaluated. Materials and Methods: Astragali Radix extract was daily given to the normal rats, control (bleomycin) and treated (bleomycin and Astragali Radix extract, 24.0 mg/10g body weight) rats for 14 days. After 14 days, we observed the change of total leukocyte count and percentage, IFN-gamma and IL-4 in BALF (Bronchoalveolar lavage fluid), and of semiquantitative histological index (SHI). Results: Compared to the control group, Astragali Radix decreased total leukocyte count (p<0.05), lymphocyte (p<0.05), neutrophil (no significance) percentage, SHI (p<0.05), IFN-gamma and IL-4 (p<0.05). Otherwise, macrophage percentage was increased (p<0.01). Conclusion: This study showed that Astragali Radix reduced the incidence of inflammatory cells and cytokines and prevented the fibrosis of tissue in bleomycin-induced lung fibrosis rats.

Pulmonary sequestration is an uncommon congenital pulmonary malformation characterized by presence of nonfunctioning lung tissue which receives its blood supply mostly from the anomalous systemic arteries - descending thoracic aorta or abdominal aorta, subclavian artery, innominated artery and internal mammary artery, etc. In our country, 39 cases were reported previously. The patient was a 40 years old woman and admitted due to productive cough for 1 year. The chest X-ray and chest C-T showed a dense mass containing a large cavity with air-fluid level and multiple radiolucent cysts in the right lower lung field. On the operative field, we could identify an aberrant large artery [ $\phi$7mm which arose directly from the descending thoracic aorta at eighth thoracic spinal level and fed the sequestrated portion of the right lower lobe. The aberrant artery was double ligation after division. Only sequestrated lobe on the superolateral lesion of the right lower lobe was resected because of nonseparated lobes in all the right lobes. An abnormal vein and bronchiole were ligated with black silk. The patient`s postoperative course was unevenful.

A ganglion cyst contains clear high viscous fluid within dense fibrous connective tissue wall communicating with joint or tendon sheath, but is not frequent around the knee joint. A hard mass at the medial side of the knee joint of the 73 years old woman, mimic to hard tumor mass was diagnosed as the ganglion using ultrasonography. Ultrasonography was a useful diagnostic tool of the cystic lesion although the consistency of the mass was hard enough to be suspected as a tumor mass.

We have earlier reported on the cloning and identification of bft-k from an enterotoxigenic strain of Bacteroides fragilis 419, which was isolated from the blood of a Korean patient who suffered from systemic infections [4,5]. The bft-k gene encodes a 397-amino-acids metalloprotease enterotoxin, and the protein has been identified as a new isoform of B. fragilis enterotoxins (BFTs), which are cytopathic to intestinal epithelial cells to induce fluid secretion and tissue damage in ligated intestinal loops [4, 6, 18, 20]. This report describes the cloning and sequencing of the enterotoxin pahogenicity islet of B. fragilis 419 which contains the bft-k gene. the cloned enterotoxin pathogenicity islet was found to have 6,045 bp in length and to contain 120bp direct repeats near its end. In the pathogenicity islet, in addition to the BFR-K, two putative open reading frames (ORFs) were identified; (1) the t-3 gene encoding a 396-amino-acids protein of a putative metalloprotease; (2) the third gene encoding an ORF of a 59-amino-acids protein, whose function has not yet beenn characterized. The expression of the t-3 gene in B. fragilis 419 was verified by western blot analysis.

Neurocysticercosis is the most common parasitic disease of the central nervous system in humans, caused by infection of the larval stage of the pork tapeworm, Taenia solium. However, cerebellar involvement is rarely reported. We report of a case of racemose cysticercosis in the cerebellar hemisphere. A 44-year-old man presented with headache and dizziness. Magnetic resonance imaging showed hydrocephalus and an ill-defined, multicystic cerebellar mass with hypersignal on T2-weighted images, hyposignal on T1-weighted images and rim enhancement after gadolinium injection. The patient underwent endoscopic third ventriculostomy and the cyst resection was done through a craniotomy. In surgical field, cysts were conglomerated in a dense collagen capsule that were severely adherent to surrounding cerebellar tissue, and transparent cysts contained white, milky fluid. Histological findings confirmed the diagnosis of cysticercosis. He received antiparasitic therapy with praziquantel after surgery. Racemose cysticercosis is rare in the cerebellar hemisphere but neurocysticercosis should be taken into consideration as a differential diagnosis of multiple cystic lesions in the cerebellum.

Allergic asthma is a chronic pulmonary inflammatory disease characterized by reversible airway obstruction, hyperresponsiveness and eosinophils infiltration. Toll-like receptors (TLRs) signaling are closely associated with asthma and have emerged as a novel therapeutic target in allergic disease. The functions of TLR3 and TLR4 in allergic airway inflammation have been studied; however, the precise role of TIR-domain-containing adapter-inducing interferon-${\beta}$ (TRIF), the adaptor molecule for both TLR3 and TLR4, is not yet fully understood. To investigate this, we developed a mouse model of OVA-induced allergic airway inflammation and compared the severity of allergic airway inflammation in WT and $TRIF^-/^-$ mice. Histopathological assessment revealed that the severity of inflammation in airway inflammation in TRIF-deficient mice was comparable to that in WT mice. The total number of cells recovered from bronchoalveolar lavage fluid did not differ between WT and TRIF-deficient mice. Moreover, TRIF deficiency did not affect Th1 and Th2 cytokine production in lung tissue nor the level of serum OVA-specific IgE, $IgG_1$ and $IgG_{2c}$. These findings suggest that TRIF-mediated signaling may not be critical for the development of allergic airway inflammation.

In this paper, we checked health problems of patients who suffered from arthritis. After assessing each patients condition, in order to alleviate their sufferings, we introduced several methods of aromatherapy as a holistic approach to these health problems. Aromatherapy is used of essential oils, which are obtained from aromatic plants, can be defined as a nature-friendly complementary/alternative method, has its great merit in its each way of application. If the arthritis condition is localized, massage,compress or poultices, and hand or foot baths are most effective. Many of essential oils in the recipe have dual benefits, as anti-inflammative and analgesic agents. The Juniper and carrot seed aid in eliminating fluid and toxin accumulation in the joint and surrounding tissue. There are many different courses available and health professional should choose one that is relevant to clinical practice. Considering the future of nursing as a major contribution in the consumer-centered structure of medical health service, aromatherapy as a complementary/alternative method is expected to contribute not only to establishing more effective health service but also to resolving chronic health problems of arthritis.

A 7-year-old, castrated, male Maltese dog presented with hyporexia and depression for 3 days. Elevated serum amylase, lipase activities, and liver enzyme values were found upon blood examination. An abdominal mass was seen on radiographs caudal to the gastric body in the left middle abdomen. In the left middle abdomen, abdominal ultrasonography also revealed a massive, irregularly marginated, heterogeneous mass of unknown origin, and in the right cranial abdomen, heterogeneously hypoechoic pancreatic tissue and hyperechoic change of adjacent mesenteric fat were observed. Contrast-enhanced computed tomography showed an irregular contour of the left pancreatic limb as well as heterogeneously enhanced parenchyma. A low-attenuating peripancreatic fluid collection with a thin and irregular wall was also seen. Based on these findings, an atypical pancreatic abscess with necrotizing pancreatitis which manifested as walled-off necrosis was suspected. The mass was excised, and the pancreatic abscess was confirmed by histopathologic examination. No complications were found in the patient after two months of follow-up examination.

We present reconstruction of a complicated scalp-dura defect using acellular human dermis and latissimus dorsi myocutaneous free flap. A 62-year-old female had previously undergone decompressive craniectomy for intracranial hemorrhage. The cranial bone flap was cryopreserved and restored to the original location subsequently, but necessitated removal for a methicillin-resistant Staphylococcal infection. However, the infectious nidus remained in a dermal substitute that was left over the cerebrum. Upon re-exploration, this material was removed, and frank pus was observed in the deep space just over the arachnoid layer. This was carefully irrigated, and the dural defect was closed with acellular dermal matrix in a watertight manner. The remaining scalp defect was covered using a free latissimus dorsi flap with anastomosis between the thoracodorsal and deep temporal arteries. The wound healed well without complications, and the scalp remained intact without any evidence of cerebrospinal fluid leak or continued infection.
