Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular lesion that is characterized by proliferation of small to medium-sized vascular structures lined by histiocytoid or epithelioid endothelial cells and often accompanied by an inflammatory infiltrate comprising lymphocytes, plasma cells and eosinophils. A 34-year-old man without any generalized systemic conditions presented with a slowly enlarging painless swelling in the buccal area. An excisional biopsy was conducted and the diagnosis of Angiolymphoid hyperplasia with eosinophilia was confirmed. We report a case of angiolymphoid hyperplasia with eosinophilia of the buccal area in oral cavity and review the previously reported cases and literatures of angiolymphoid hyperplasia with eosinophilia.

Deep Ocean Water is formed within restricted area including polar sea (high latitude) by cooling of surface seawater and globally circulated in the state of insolation with surface seawater. Although not as obvious as estuaries mixing, Brine groundwater is mixture of recirculated seawater and groundwater. Seawater having high osmotic pressure infiltrate into unconfined aquifer where is connected to the sea. The ions dissolved in seawater are present in constant proportions to each other and to the total salt content of seawater. However deviation in ion proportions have been observed in some brine groundwater. Some causes of these exception to the Rule of constant proportions are due to many chemical reactions between periphery soil and groundwater. While Deep Ocean Water (DOW) have a large quantity of functional trace metals and biological affinity relative to brine groundwater, DOW have relatively small amount of harmful bacteria and artificial pollutants.

Mycoplasma Pneumonia is a main cause of primary atypical pneumonia and may present in a variety of ways. One auther has stated that the infiltrate is of a lobar segmental type, while others have found the infiltrates to be mainly reticular or interstitial. We experienced a case of mycoplasama pneumonia, which progressed to ARDS pattern rapidly an6 recovered completely after ventilator care.

Diffuse sclerosing papillary carcinoma(DSPC), a variant of papillary carcinoma of the thyroid, is characterized by diffuse involvement of one or both thyroid lobes, and histologic features such as prominent sclerosis, intense lymphocytic infiltrate, numerous psammoma bodies, and squamous metaplasia together with the characteristic cytoarchitectural pattern of classical papillary carcinoma. We experienced a case of fine needle aspiration cytologic(FNAC) findings of DSPC, which was confirmed by histologic examination of the thyroidectomy specimens. The patient was 26 years old female who presented with diffuse firm enlargement of the thyroid gland with enlargement of many cervical lymph nodes. FNAC smears showed numerous psammoma bodies, many lymphocytes, metaplastic squamous cells, absence of stringy colloid, and epithelial cells showing classical features of papillary carcinoma, such as nuclear grooves, intranuclear unclusions, and ground glass chromatin pattern.

Idiopathic acute eosinophilic pneumonia (IAEP), characterized by acute febrile respiratory failure associated with diffuse radiographic infiltrates and pulmonary eosinophilia, is rarely reported in children. Diagnosis is based on an association of characteristic features including acute respiratory failure with fever, bilateral infiltrates on the chest X-ray, severe hypoxemia and bronchoalveolar lavage fluid >25% eosinophils or a predominant eosinophilic infiltrate in lung biopsies in the absence of any identifiable etiology. We present a 14-month-old girl who was admitted to our pediatric intensive care unit because of acute respiratory distress. She had a fever, dry cough, and progressive dyspnea for 1 day. Chest X-ray showed multifocal consolidations, increased interstitial markings, parenchymal emphysema and pneumothorax. IAEP was confirmed by marked pulmonary infiltrates of eosinophils in the lung biopsy specimen. Most known causes of acute eosinophilic pneumonia, such as exposure to causative drugs, toxins, second-hand smoking and infections were excluded. Her symptoms were resolved quickly after corticosteroid therapy.

Authors report a very rare case of primary Hodgkin's lymphoma limited to the cerebellum. A 64-year-old female patient presented with headache, nausea, and vomiting. Magnetic resonance imaging of the brain revealed a nodular enhancing mass in the left cerebellar hemisphere. Tumor was removed totally with retromastoid suboccipital approach. Diagnosis was Hodgkin's lymphoma of mixed cellularity type, consisting of a dense mixed inflammatory infiltrate containing scattered large atypical mononuclear Hodgkin's cell and multinucleated Reed-Sternberg cells. Systemic work-up for the Hodgkin's lymphoma was followed with negative result. Postoperative radiation therapy was given and the patient is disease-free at 16 months after the operation.

Angiolymphoid hyperplasia with eosinophilia(ALHE) is an uncommon idiopathic condition that presents with isolatedor grouped cutaneous plaques or nodules of the head and neck. Extracutaneous involvement is rare. ALHE is a distinct pathologic entity marked by a proliferation of blood vessels with distinctive large endothelial cells accompanied by a characteristic inflammatory infiltrate that includes eosinophils. The lesion is benign but may be persistent and difficult to eradicate. The authors have recently experiecned a case of angiolymphoid hyperplasia with eosinophilia in a 52-year-old male who had a painless enlarging mass in his right preauricular area and external ear canal for several years. We present this case with the review of literatures.

Al$_{2}$O$_{3}$ ceramic coating layer by gas flame spraying was very porous, therefore it could not have wear and corrosion resistance at all. To get a dense and strong coating layer, a method to infiltrate an alloy into the pores of $Al_{2}$O$_{3}$ ceramic coating was investigated. Cu-Ti alloys, which had good wettability and reactivity with $Al_{2}$O$_{3}$ ceramic, were examined for infiltration. Infiltration of the alloys was performed in vacuum at 1100.deg.C. The melt of Cu-50 at % Ti alloy was well penetrated through the porous $Al_{2}$O$_{3}$ coating and tightly sealed the pores, unbounded area and microcracks in the coating. The alloy melt in the pores reacted with $Al_{2}$O$_{3}$ ceramic to produce a suboxide phase, Cu$_{2}$Ti$_{4}$O. This composite layer which was composed of $Al_{2}$O$_{3}$ and Cu$_{2}$Ti$_{4}$O phase had good microstructure and wear and corrosion resistance. Additionally, microstructures at interfaces between coating layers were greatly improved owing to the effect of vacuum heat treating.

The aim of this work is to show the way of manufacturing the SiC mechanical seal at the low temperature of 130$0^{\circ}C$ using clay and frit as source of secondary phase. $\alpha$-SiC and $\beta$-SiC powder which showed different distribution of particle were used as starting materials, i.e. average particle size of $\alpha$-SiC was larger than that of $\beta$-SiC. The mechanical and tribological properties of two groups of specimen, i.e. one contained mainly larger $\alpha$-SiC powder and the other mainly fine particle $\beta$-SiC, were measured. The specimen consisted of larger $\alpha$-SiC exhibited lower density flexural strength and wear resistance is comparison with these of sample containning mainly $\beta$-SiC . This difference could be originated from the dependence of capillary force on the particle size. For the larger SiC particle, the liquid phase may not fill the whole pores during sintering, due to low capillary force, whereas the liquid phase can infiltrate into the small ores surrounded small $\beta$-SiC particle. Thus, the course of high flexural strength and high wear resistance of specimen prepared using small particles can be explaced from the easy infiltration of liquid phase.

Subacute necrotizing lymphadenitis is characterized by cervical lymphadenpathy in young patients and mistaken for malignant disease both clinically and histologically. Microscopically, there is a varying degree of effacement of the lymph node architecture and necrosis with an infiltrate of histiocytic cells and absence of polymorphs. We have experienced 4 cases of cervical lymphadenopathy accompanied by fever. All cases had complete recovery to conservative treatment only. The excised lymph nodes were moderately enlarged and typically showed varying degree of necrotizing lesions, and abundant karyorrhectic debris, scattered fibrin deposits, aggregates of large mononuclear cells, and a paucity of plasma cell and neutrophils. For investigating the etiology and pathogenesis of this lesion, further clinical study and stepwise pathologic and immunologic planning would be valuable.
