Subcutaneous tissue calcification in rheumatic diseases usually occurs in connective tissue diseases, such as systemic lupus erythematosus, scleroderma, and dermatomyositis. Domestic cases of calcification in rheumatoid arthritis have not been reported. The mechanism of subcutaneous tissue calcification may differ depending on the cause and it can develop on all parts of the body. Calcification occurring in rheumatic diseases is a major mechanism of tissue damage caused by chronic inflammation. No standard therapy for calcification has been established; however, many studies have reported on medical and surgical treatment. We report on subcutaneous tissue calcification in a rheumatoid arthritis patient tissue calcification on both sides of the buttocks, the upper limbs, and the lower limbs.

Arterial tortuosity syndrome (ATS) is a very rare autosomal recessive connective tissue disease characterized by generalized elongation and tortuosity of the medium- to large-sized arteries, and other systemic connective tissue manifestations. To date, this disease entity has not been reported in Korea. We report a case of ATS diagnosed in a neonate who presented with severe elongation and tortuosity of the aorta and its major branches, as well as the intracranial arteries. Additionally, the patient presented with a tortuous dilatation of the inferior vena cava, an aneurysmal dilatation of the extra-hepatic bile ducts, and an inguinal and sliding hiatal hernia. The diagnosis was confirmed using DNA sequencing analysis, and the patient demonstrated a compound heterozygosity for two novel mutations (c.738delG [p.Gln247Serfs*33] and c.362T>C [p.Ile121Thr]) in exon 2 of the SLC2A10 gene. Genetic analysis also confirmed that both parents were heterozygous carriers of the responsible mutations. Owing to such clinical manifestations, ATS is often misdiagnosed as other connective tissue diseases including Loeys-Dietz syndrome, Marfan syndrome, and Ehlers-Danlos syndrome. In patients presenting with a high index of suspicion, thorough clinical evaluation and screening for ATS including computed tomography or magnetic resonance angiography and target gene analysis are necessary for early diagnosis and management.

Exaggerated acute and late toxicities following radiotherapy have been reported in patients with pre-existing connective tissue diseases, such as systemic lupus and scleroderma. Behcet's disease (BD) is a relapsing multisystem connective tissue disease characterized by vasculitis in the mucocutaneous, ocular, gastrointestinal, respiratory, neurologic, urogenital, articular, and cardiovascular systems. Data concerning the relationship between radiotherapy toxicity and BD are limited in the literature. Here, we report a case of lung cancer treated with radiotherapy (60 Gy) in a patient with BD. No severe radiation-induced toxicity was observed. Radiation-induced toxicity in patients with BD has also been discussed.

The present paper deals with mortality and pathogenetic investigation of the oysters Crassostrea gigas cultured by tile coventional bamboo and hanging method in Kimhae and Koje-Do in 1969. The results of the investigation may be summarized as follows: 1. Mortality of the oysters by the bamboo method in Kimhae was $9.5\%$ in June, $10.2\%$ In July, $12.3\%$ in August and $12.1\%$ in September, respectively, 2. Mortality of the oysters cultured by the hanging method in Koje-Do was $2.4\%$ in June, $2.9\%$ in July, $30.7\%$ in October, $37.3\%$ in November and $30.0\%$ in December, respectively 3. The diseased oysters had severe inflammation, necrosis and multiple abscess in the epithelia of stomach, mid-gut, digestive tubules, blood vessels and gonads, mucous membrane and surrounding tissue. 4. From August gram negative bacteria were found in the nodules of connective tissue and multiple abscess of the diseased oysters. Particularly the connective tissue of the diseased oysters contained more bacteria than epithelia. 5. Since the bacteria are less abundant in the region of digenerated tissue, mortality of the oysters is not caused only by the infectious bacteria but seems that is also caused by other environmental factors such as extreme temperatures and salinities.

Objectives : This paper aims to examine situations that were conceived as incurable at the time of publication of the 『Huangdineijing』. Methods : The texts of the 『Huangdineijing』 were searched for contents which included 'cannot be cured.' Next, the verses were examined within their context, after which those that specifically indicated 'incurability' were selected. These were categorized according to content, then organized to better show the situations that were seen as incurable to the authors of the 『Huangdineijing』. Results : The conditions deemed incurable in the 『Huangdineijing』 were bloody and purulent stool, ascites, tumors, some purulent inflammation, some infectious diseases with fever, wasting thirst, chronic kidney disorder, some diseases of the connective tissue, epilepsy, cardiac infarction, and cerebrovascular diseases. Internal damage due to acupuncture and poor patient attitude could also contribute to incurability. Conclusions : The authors of the 『Huangdineijing』 were unable to cure some conditions that are currently being cured by Korean Medicine.

Several detailed aspects of medical care services during one year (Aug 1, $1982{\sim}$July 31, 1983) were compared between two community health sub-centers; one (A) was served by a local clinician, the other (B) by a trainee of preventive medicine. The results were analysed as follows: 1. Total spells of medical services during the same period in 'A' sub-center was 4,087 and that in 'B' 2,347. Medicaid visitors in 'A' was 1,051 (25.7% of the total), that in 'B' was 250 (10.7%). Significant difference was observed. 2. Average number of visits for the same case in 'A' was 2.0, that in 'B' was 1.4. Average duration of service by day for the same case in 'A' was 3.9, that in 'B' 3.0. 3. Average cost of service for a case in 'A' was 6,770 won, that in 'B' 4,230 won. 4. Difference in age distribution of visitors in the two sub-centers was insignificant. $0{\sim}9$ year group was 38.5% of the total. Difference in distribution by sex (between two sub-centers) was minimal. Male utilisers more than female by ca. 10%. 5. Concerning distribution of visitors by month, utilisation in July, August and September was the highest; the sum of them was 32.7% of the total in 'A' and 32.9% in 'B'. 6. Distribution by diagnoses in 'A' in decreasing order of frequency was Respiratory system diseases (26.1%), Digestive system diseases (23.0%), Diseases of skin and subcutaneous tissue (17.4%), Accidents and poisoning (11.5%) and Diseases of musculoskeletal system and connective tissue (5.4%). That in 'B' was Respiratory system diseases (39.0%), Digestive system diseases (23.0%), Diseases of skin and subcutaneous tissue (14.2%), Accidents and poisoning (10.9%) and Infection and parasitic diseases (9.1%). 7. The 10 most frequent diagnoses comprised 68.5% of the total in 'A' and 65.5% in 'B' 8. Utilisation by accessibility to each sub-center was studied. It is shown that the nearer the distance or the easier the accessibility, the more visits to services. The distinct pattern is manifested in the utilisation in 'A'-Myun.

Matrix metalloproteinases (MMPs) are a family of host-derived proteolytic enzymes and implicated in the remodeling and degradation of extracellular matrix under both physiological and pathological conditions. Connective tissue degradation in periodontal diseases is thought to be due to excessive MMP activities over their specific inhibitors. The effects of lipopolysaccharide (LPS) from Prevotella intermedia, one of the major putative pathogens of periodontitis, on the expression of mRNA for MMPs and tissue inhibitors of metalloproteinases (TIMPs) in human gingival and periodontal ligament fibroblasts were examined by reverse transcriptase-polymerase chain reaction (RT-PCR). The expression of mRNAs encoding MMP-1, -2, -3, -10, and -14 was increased in human gingival fibroblasts treated with p. intermedia LPS, whereas MMP-11 and TIMP-2 mRNA expression was decreased in these cells stimulated with LPS. P. intermedia LPS increased the MMP-1, -2, -10, -11, and -14 mRNA expression and decreased TIMP-1 and -2 mRNA expression in human periodontal ligament fibroblasts. These findings imply that P. intermedia LPS may play an important role in the connective tissue degradation in periodontitis.

Fever of unknown origin (FUO) has been a convenient term used to classify patients who warrant a particular systemic approach to diagnostic evaluation and management. The greatest clinical concern in evaluating FUO is identifying patients whose fever has a serious or life-threatening cause when a delay in diagnosis could jeopardize successful intervention. Thorough history and complete physical examination are critical to uncover the etiologic diagnosis. Most cases of FUO in children are caused by atypical presentations of common diseases rather than by typical manifestations of rare disorders. Selection of diagnostic tests and speed of investigation should be guided by a knowledge of the disease severity, patient age, epidemiologic and geographic information, and any positive findings from a detailed history and physical examination. The three most common causes of FUO in children are infectious diseases, connective tissue diseases, and malignancy. In general, the prognosis of FUO in children is better than that of adults. Although the outcome is dependent on the primary disease process, fever abates spontaneously in most cases in whom the cause of fever remains unclear.

The gingiva consists of an epithelial layer and an underlying connective tissue layer. The oral epithelium is a keratinized, stratified, squamous epithelium. The epithelium can be divided into the following cell layer: basal layer, prickle cell layer, granular cell layer and keratinized cell layer. The desquamative disease of gingiva means exfoliative diseases of epithelial layer on the gingiva. The chronic desqumative gingivitis is usually related to the dematologic disorders that produce cutaneous and mucous membrane blisters. The cicatricial pemphigoid and lichen planus are representative diseases of the dermatologic cases. Patients may be asymptomatic or symptomatic. When symptomatic, their complaints range from a mild burning sentation to an severe pain. The clinical examination must be considered with a thorough history, and routine histologic and immunofluorescence studies. A systemic approach needs to achieve accurate diagnosis and treatment of the gingival desquamative diseases.

Periodontal disease is an inflammatory disease that affects the destruction of the bone supporting the tooth and connective tissues surrounding it. Periodontal ligament fibroblasts (PDLFs) induce overexpression of matrix metalloproteinase (MMP) involved in periodontal disease's inflammatory destruction. Osteoclasts take part in physiological bone remodeling, but they are also involved in bone destruction in many kinds of bone diseases, including osteoporosis and periodontal disease. This study examined the effect of baicalin on proteolytic enzymes' production and secretion of inflammatory cytokines in PDLFs and RAW 264.7 cells under the lipopolysaccharide (LPS)-induced inflammatory conditions. Baicalin inhibited the expression of the protein, MMP-1 and MMP-2, without affecting PDLFs' cell viability, suggesting its possibility because of the inhibition of phosphorylation activation of mitogen-activated protein kinase's p38, and the signal transduction process of nuclear factor κB (NFκB)-related protein. Also, baicalin reduced the expression of MMP-8 and MMP-9 in RAW 264.7 cells. This reduction is thought to be due to the inhibition of the signal transduction process of NFκB-related proteins affected by inhibiting p65RelA phosphorylation. Also, baicalin inhibited the secretion of nitric oxide and interleukin-6 induced by LPS in RAW 264.7 cells. These results suggest that baicalin inhibits connective tissue destruction in periodontal disease. The inhibition of periodontal tissue destruction may be a therapeutic strategy for treating inflammatory periodontal-diseased patients.
