봉와직염은 대부분이 A군 연쇄구균이나 황색포도구균에 의해 발생하는 것으로 알려져있다. 저자들은 관상동맥 우회술을 위한 정맥절제술을 받았던 과거력이 있고 족부백선이 있었던 환자에게서 혈액배양검사에서 확인된 G군 연쇄구균에 의한 봉와직염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Group A streptococci and Staphylococcus aureus are responsible for the overwhelming majority of cases of cellulitis. But, streptococci belonging to other group (group C, group G, and in neonates particularly, group B) are sometimes the etiologic agents. Diagnosing the etiology of cellulitis rests on isolating an organism from blood cultures, skin biopsy, or tissue aspirate. We experienced a case of a group G streptococcal cellulitis that identified by blood cultures, which is relatively rare in Korea and treated the patient with cefazolin.

Coccidioidomycosis results from inhaling the spores (arthroconidia) of Coccidioides species (Coccidioides immitis or Coccidioides posadasii), and is endemic in the southern United States. An even smaller proportion of all infections result in illnesses related to extrapulmonary infection. We report a case of coccidioidomycosis manifested as pelvic bone and paravertebral abscess in a Korean who has visited LA. Culture and pathology from the pelvic bone and paravertebral mass revealed Coccidioides immitis, and a diagnosis of disseminated coccidioidomycosis was made. 콕시디오이데스 진균증은 미국 남서부 지역의 풍토병으로 알려져 있고 우리나라는 유행지역이 아니기 때문에 진단에 혼선 및 지연을 초래할 수 있다. 그러나 해외여행자의 증가와 함께 다른 지역에서의 발병 사례가 증가하고 있으므로 임상양상과 진단이 맞지 않는 경우 환자의 유행지역의 여행력 여부에 대한 문진이 필수적이라 하겠다. 본 저자들은 콕시디오이데스 진균증의 토착지역인 미국 LA지역을 방문한 후 발생한 골반과 척추부위를 침범한 콕시디오이데스 진균증 1예를 경험하고 항진균제 사용과 함께 수술적 치료를 병행하여 치료하여 이를 보고하는 바이다.

다운증후군은 특이한 외모, 지능 발달 저하 등의 임상상으로 나타나는 가장 흔한 상염색체 수 이상 증후군이다. 저자들은 전신 경련을 주소로 내원한 환자에서 염색체 검사를 실시하여 Robertsonian translocation에 의한 부분 삼체성의 다운증후군 및 특발성 부갑상선 기능저하증이 동반된 증례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Down syndrome is perhaps the oldest condition associated with mental retardation and the most common genetic cause of developmental disability. It is presumed that the additional gene products of the triplicated chromosome 21 cause alterations in the normal processes regulating embryogenesis. Ninety-five percent of cases are caused by trisomy 21, whereas the remainder are translocations. Mainly, the chromosomal translocation is made of Robertsonian translocation. Clinically it consists of cranio-facial abnormality, such as microcephaly, with flattening both of the occiput and face, an upward slant to the eyes with epicanthal folds, and the ears are small. Congenital heart disease, musculoskeletal abnormalities, gastrointestinal disorders, hematologic abnormalities and associated developmental disabilities. And thyroid dysfunction and infertility are the most significant endocrinologic disorders in individuals with Down syndrome. But we could not find any reported case of hypoparathyroidism associated with Down syndrome in worldwide search of literatures. Even though some cases of hereditary hypoparathyroidism, which is not associated with Down syndrome were reported. We experienced a rare case of 15-year-old male diagnosed as hypoparathyroidism associated with Down syndrome, which is diagnosed by cytogenetic chromosomal study and by radioimmunoassay for PTH wish symptoms of seizure disorder due to hypocalcemid and typical cranio-facial abnormalities.

순환유동층(내경 0.1 m, 높이 5.3 m)에서 층물질로 FCC 입자를 사용하여 기상유속(1.5-3.5 m/s)과 고체순환 속도(10-50 ㎏/㎡s)가 축방향 고체체류량 분포에 미치는 영향을 연구하였다. 상승관내의 고체체류량은 고체순환속도가 증가할수륵 증가하였고, 기상유속이 증가함에 따라 감소하였다. 상승관내의 축방향 고체체류량 분포는 하부에 고체체류량이 높은 농후상 영역에서 상부에 고체체류량값이 거의 일정하고 낮은 희박상영역으로 높이에 따라 감소하는 형태를 나타내었다. 희박상내의 고체체류량은 기상유속, 고체순환속도와 slip factor를 이용하여 예측이 가능하였고, slip factor가 2-4의 범위내에서 실험값과 예측된 값이 잘 일치하였다. 상승관내의 축방향 고체체류량 분포에 대한 상관식을 무차원군을 이용하여 제시하였다. The effects of gas velocity(1.5-3.5 m/s) and solid circulation rate(10-50 ㎏/㎡s) on the axial solid holdup distribution have been determined in a 0.1 m-I.D.×5.3 m-high circulating fluidized bed. Solid holdup in the riser increases with an increase in solid circulation rate, but decreases with increasing gas velocity. The solid holdup decreases from the dense phase at the bottom to the dilute phase at the top section of the riser. The solid holdup in the dilute phase can be predicted from the ratio of solid to gas velocities and slip factor in the range of 2-4. The axial solid holdup distribution in a circulating fluidized bed has been correlated with the pertinent dimensionless groups.

It was regarded that the $^{31}P$ resonances of inherent nucleotides in $F_1$-ATPase (EF1), as large as 380KDa, could not be observed by $^{31}P$ NMR spectroscopy. However, our $^{31}P$ NMR spectroscopy could differentiate between different nucleotide binding sites on EF1 from Escherichia coli. When EF1 was prepared in the absence of $Mg^{2+}$, EF1 contained only ADP. Multiple $^{31}P$ resonances from $\beta$-phosphates of ADP bound to the EF1 were observed from the enzyme prepared without $Mg^{2+}$, suggesting asymmetry or flexibility amongst nucleotide binding sites. $^{31}P$ resonances from enzyme bound ATP could be observed only from EF1, when the enzyme was prepared in the presence of $Mg^{2+}$. This $Mg^{2+}$ dependent ATP binding was very tight that, once bound, nucleotide could not be removed even after removal of $Mg^{2+}$. $^{31}P$ NMR proved to be a valuable tool for investigating phosphorous related enzymes.

Alpha-fetoprotein (AFP) is well-known as a useful tumor marker, especially for hepatocellular carcinoma and yolk sac tumors, and there are many kinds of neoplasms that produce AFP, with gastric adenocarcinoma being the most common. In 1970, Bourreille et al. reported the first case of stomach cancer with an elevated AFP level. In 1985, Ishikura et al. reported that an AFP-producing gastric adenocarcinoma had features of hepatic differentiation and proposed that such gastric carcinomas should be collectively called $quot;Hepatoid Adenocarcinomas of the Stomach$quot;. We experienced a case of so-called hepatoid adenocarcinoma of the stomach in a 54-year-old male patient, who was diagnosed as double primary cancer of gastric adenocarcinoma and hepatoma and who underwent a subtotal gastrectomy and right lobectomy of the liver. We report this case with a review of the literature.

Total 210 heads of the dairy cattles imported in Chung Nam Area from Canada and others were used to obseve by the Clinico-hematological examination for the infection states of the So-called small type Piroplasmosis. The results obtained were summarized as follows; 1. The infection ratio of the Piroplasma on the imported cows were showed 15 percent of 120 heads in first year(1969), 17% fo 90 in the second (1970) and the ratio of total 210 were about 16%. 2. Comparing with Kyung Pook Area the infection ratio of the Piroplasmosis were notably obtained low results. According to the distribution of the agent "ticks" they were seemed to be the different Area. 3. The dairy cattles which have already been rearing in this country seem to be able to infect without regard to age when if they were obtained a chance of infection 4. The application of the treatment medicines "Pamaquine and others" were temporarily proved to be good effects. And about 4 weeks after, treatment will be repeated reasonable to require improvement.
