Abstract
1,25 Dihydroxyvitamin D3 is a differentiation inducer for monocytic cell. It can induce a monoblastic cell line U937 to differentiate. In this paper, we report that by inducing the differentiation of U937, 1,25-dihydroxyvitamin D3 increased urokinase activity expression on U937 cell surfaces. After incubation of the cell with various concentrations of 1,25-dihydroxyvitamin D3, the cell line showed a remarkable progressively increasing membrane-associated urokinase activity in a dose dependent manner. On the contrary, plasminogen activator inhibitor activity which was found in the culture medium is not modified by the 1,25-dihydroxyvitamin D3 induction. This results suggests another role of 1,25-hydroxyvitamin D3 in the treatment of myelofibrosis, since enhanced plasmin generation can accelerate the activation of procollagenase. The induced plasmin and collagenase activities surrounding the monocytic cells may participate in the physiological and pathological events, especially in the connective tissue degradation.

Abstract
The Barbash strain of spotted fever group rickettsia was reexamined in this study by the microimmunofluorescence test with mouse antisera and with monoclonal antibodies. Protein immunoblotting was performed for comparison of purified antigens of R. rickettsii, R. sibirica, R. conorii and Barbash strain. Comparison of Barbash strain, R. rickettsii (Sheila Smith strain), R. conorii (Malish 7 strain), and R. sibirica (strains 232, 246 and Jinghe-74) of the spotted fever group in the microimmunofluorescence test of Philip et al. revealed that Barbash strain has antigens that yield homologous titers with the R. conorii strains and differ from R. sibirica and R. rickettsii. Monoclonal antibodies specific for R. conorii react at identical titres with the Barbash strain, and a monoclonal antibody specific for R. sibirica does not react with the Barbash strain. Likewise, T-cell hybridomas reactive with R. conorii but not R. sibirica yield a strong response when stimulated by Barbash strain antigens. Western immunoblotting with the same polyclonal and monoclonal antibodies confirmed the presence of specific protein antigens of R. conorii and different protein antigenic composition of R. sibirica when compared with Barbash strain. Thus, Barbash strain is a strain of R. conorii.

Abstract
The rat fibroblast cell line Rat 1 was transfected with total DNA of a gastrocarcinoma cell line, BGC-823. The transforming gene was cloned from the genomic library of the secondary transformants using in situ hybridization with a probe of the human Alu repeat sequence. This cloned gene is homologous to the protooncogene c-Ha-ras. The activation lesion of the transforming gene was identified by sequence analysis as a single nucleotide substitution of thymine for guanine in the 12th codon. This results in the substitution of valine for glycine at the 12th amino acid of the Mr 21,000 protein.

Abstract
Gamma interferon (IFN-gamma) plays an important role as a host defense in rickettsial infection. Swiss Webster mice, which are resistant to Rickettsia conorii (Malish 7 strain) infection, were treated with a monoclonal antibody against mouse IFN-gamma. When the antibody-treated mice were inoculated with 12 50% tissue culture infective doses of R. conorii, the mortality was 47% and the morbidity was 100%. None of the control mice, which received the same dose of R. conorii, died or became ill. The enumeration of rickettsiae in organs by direct immunofluorescence in paraffin sections demonstrated higher quantities of rickettsiae in the spleen had liver of IFN-gamma-depleted mice as compared with those of the infected controls. The kinetic analysis of IFN-gamma levels in sera showed depletion in the treated mice. These results indicate that IFN-gamma plays an important role as a host defense in the early stage of rickettsial infection. Survival of some mice despite continued treatment with antibody to IFN-gamma suggests that other immune mechanisms may also be important.

Abstract
A new postcolumn derivatization method for the fluorometric determination of streptomycin in serum by high-performance liquid chromatography is described. The serum was treated with 3.5% perchloric acid to precipitate proteins and the supernatant was directly injected into the chromatograph. Streptomycin was separated by reversed-phase, ion-pair chromatography with a mobile phase containing ninhydrin as a fluorogenic reagent, octanesulfonate, and 1,2-ethanedisulfonate as counterions, and was detected by fluorescence using continuous-flow, postcolumn derivatization in an alkaline stream with ninhydrin in the mobile phase. This method is sensitive to 1.0 microgram/ml using only 100 microliter of serum. Comparison with a fluorescence polarization immunoassay gave a good correlation coefficient of 0.976.

Abstract
DNAs of three cell lines of human gastrocarcinoma (MGC-803, BGC-823 and PACM-82) and two fresh solid tumors of human stomach cancer were used to transfect NIH3T3 and Rat-1 cells. The transformed cells were selected with high concentration of glucose and low concentration of serum, or with medium containing Geneticin (G418) after co-transfection of pSVneo and DNAs of stomach cancer cell line or primary transformants. From the second round transfection, we had obtained transformants which could grow with high colony forming efficiency in soft agarose and were tumorigenic in nude mice. The southern blot analysis showed that the cellular DNA of the transformants contained human Alu repeat sequence and the transformed gene from stomach cancer cell line (BGC-823) and was homologous to proto-oncogene c-Ha-ras. The transforming gene is able to induce neoplastic transformation of NIH3T3 and Rat-1 cells.
