In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

N/A Clinical studies were carried out on 14,389 cases who had taken gastrofiberscopic examination, biopsy and X-ray from May, 1969 to May, 1984 in Han-Yang University Hospital. The results obtained were as follows; 1) Of total 14,389 cases, 7,916 were male and 6,473 were female. 55.1%, of the cases were in the 3rd and 4th decade. 2) Of total 14, 389 cases, 13, 615 showed abnormal endoscopic findings. In abnormal cases, male to female ratio was l.2: l.3) The incidence of single organ involved was 84.8% and multiple organs involved was In single organ involved cases, the most common site of disease was stomach and in multiple organ involved cases, the prevalent sites of lesions were stomach and duodenum. 4) The most frequent disease of stomach was gastritis followed by gastric ulcer. In the cases of duodenum, the most common disease was duodenal ulcer and the next was duodenitis. 5) The most prevalent disease was the chronic gastritis, and the frequency of the other upper gastrointestinal diseases was acute gastritis, gastric ulcer, stomach cancer and duodenal ulcer in orders. 6) The most frequent type of chronic gastritis was superficial gastritis. 7) Among the total cases which had been taken blood-typing, the incidence of most upper gastrointestinal diseases was not related to each blood type. But blood group 0 was common in peptic ulcer disease and blood group A in stomach cancer. 8) The clinical symptoms and signs were of no significant aid for the differential diagnosis of the various upper gastrointestinal diseases.

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)
콘크리트 구조물용 GFRP리바의 기계적 특성에 관한 연구

In this paper was studied on the mechanical characteristics of Glass Fiber Reinforced Plastics(GFRP) of the steel bar it is to replace The advantage of FRP such as high strength low weight and chemical inertness or noncorrosiveness can be fully exploited. GFRP bar were successfully fabricated at 10mm nominal diameters and hollow types using a pultrusion method Tensile and bending specimens from this bar were tested and compared with behavior of GFRP rebar and steel bar.

One of the primary functions for which bones have evolved is to act as structural support. To achieve this goal, bones are remodeling throughout life so that their structure remains optimal for the prevailing mechanical environment. Bone remodeling consists of an initial phase of osteoclastic bone resorption followed by a bone formation period. Prostaglandins are potent regulators of bone formation and bone resorption that can have both stimulatory and inhibitory effects. Elevation of intracellular cAMP is an important intracellular signaling mechanism involved in the regulation of the expression of many proteins. In this study, the author examined whether PGE_2 or DBcAMP affected osteoblastic activation or osteoclastic differentiation in mouse bone marrow cells and osteosarcoma ROS 17/2.8 cells. The effect of PGE_2 and DBcAMP on the cell proliferation was measured by the incorporation of [^3H]-thymidine into DNA. From the result, PGE_2( 0.5-1 ㎍/ml ) and DBcAMP(0.1-0.5 mM) inhibited the [^3H]-thymidine incorporation into DNA. The effect of PGE_2 and DBcAMP on the induction of alkaline phosphatase(ALP) was investigated in ROS 17/2.8 cells cultured in medium containing 0.4% fetal bovine serum. PGE_2 and DBcAMP stimulated ALP activity in the cells. PGE_2 also increased the intracellular cAMPs contents with a maximal effect at 0.5 ㎍/ml. ROS 17/2.8 cells released nitric oxide upon stimulation of PGE2 or DBcAMP with interferon-γ. PGE_2 and DBcAMP increase the phosphorylation level of CREB(cAMP response element binding protein) without any change on the amount of CREB protein. Also, PGE_2 (10^-6 M) and DBcAMP (10^-4 M) significantly increase the generation of osteoclast-like cell in mouse bone marrow cell culture system. In conclusion, the results of this study suggested that PGE_2 and cAMP should appear to be an important regulatory molecule in the processes of bone formation and resorption.

Experiments had been made to evaluate more efficient method in stool examination for various helminth ova. Authors examined 2,016 nationwidely collected stool specimens by the two methods, cellophane thick smear method and brine floatation method. The results were as foliows; 1. Of 2,019 specimens examined by cellophane thick smear method, the positive rates of following helminth ova were; Ascaris lumbricoides (fertilized) 27.3% Ascaris lumbricoides (unfertilized) 13.6%, Trichuris trichiura 39.0%, Hookworm 0.1%, Enterobius vermicularis 0.05% Hymenolepis nana 0.04%, Taenla spp. 1.3% Clonorchis sinensis 1.1% and Metagonimus yokogawai 5.7%. And, A. lumbricoides (fertilized) 27.0%, A. lumbricoides (unfertilized) 3.8%, T. trichiura 38.1%, Hookworm 2.0%, Trichostrongylus orlentalis 0.6%, E. vermicularis 0.2%, H. nana 0.8%, and M. yokogawai 0.05% by brine floatation method. 2. The causes of inferior positive rates in some helminth ova by cellophane thick smear method were shortly discussed and suggest some opinions in improvement of detection ability. 3. The positive rates of following helminth ova were superior in cellophane thick smear method to those of brine floatation method: A. lumbricoides(fertilized), Taenia spp., C. sinensis and M. yokogawai. And, the positive rates of following helminth ova were superior in brine floatation method: Hookworm T. orientalis, H. nana and E. vermicularis. 4. Cellophane thick smear method has been known to be one of the most effective methods in mass stool examination. But, this method is not so effective in detection of certain species of helminth ova. Therefore, employment of brine floatation method added to cellophane thick smear method is desirable for the better result of mass stool examination.
