genomic dna with transformation-related activity and melanoma antigen expression.we have analyzed the mouse melanoma antigen with monoclonal antibodies established by syngeneic immunization. to further understand the structure of this antigen at a molecular level, we have cloned the genomic dna controlling the expression of melanoma antigen by cosmid library transfection and a monoclonal antibody. in the process of analyzing this dna fragment we found that it contained a gene related with transformation, which was proved by tumor formation in nude mice inoculated with nih/3t ...19892715661
the effects of six environmental variables on pasteurella multocida populations in water.the effects of protein, ph, temperature, sodium chloride (nacl), clays, sucrose, and their interactions on the survival and growth of pasteurella multocida were evaluated. pasteurellae populations declined rapidly in waters maintained at 2 c, compared to 18 c. increasing water soluble proteins by 175 micrograms/ml, and nacl by 0.5%, greatly enhanced survival of p. multocida, whereas variations in ph, clays, and sucrose had relatively minor effects. pasteurella multocida survived for over 1 yr in ...19892716103
epizootiological features of avian cholera on the north coast of california.an avian cholera (pasteurella multocida) epizootic was observed among wildfowl at the centerville gun club, humboldt county, california (usa) in january 1978. compared to their live populations and use of the area, coots (fulica americana) died in proportionately greater numbers than any other species. coots collected by gunshot were evaluated for sex and age composition, and morphometry from november 1977 through mid-january 1978 at this site. there was no substantial difference in the sex, age ...19892716104
the effect of arterial oxygen content on the results of radiation therapy for epidermoid bronchogenic carcinoma.anemia is believed to be an important prognostic factor in treating cancer patients by radiation therapy. one possible explanation for this is tumor oxygenation. with respect to tumor oxygenation, the arterial oxygen content (cao2) may be of more importance than the hemoglobin (hb) level. this study shows the relationship between the cao2 and tumor response to radiation therapy. forty-two patients with epidermoid bronchogenic carcinoma, treated by irradiation alone between april 1982 and march 1 ...19892722590
field trial of a live streptomycin dependent pasteurella multocida serotype a:12 vaccine in rabbits.a live, streptomycin dependent, pasteurella multocida (sdpm) serotype a:12 vaccine was evaluated for preventing pasteurellosis in two commercial rabbitries. rabbits were inoculated intranasally at 5 weeks old with either 0.25 ml of vaccine containing 10(8) colony forming units/ml or 0.25 ml of diluent (control). a proportion of rabbits received a second intranasal inoculation 1 month later. partial protection against p. multocida infection was observed 1 and 2 months after inoculation in rabbits ...19892724923
