A NEW ESTROGENIC SUBSTANCE PRESENT IN THE NEUTRAL FRACTION OF HUMAN PREGNANCY URINE     

Dorfman RI 《Science (New York, N.Y.)》1940,92(2399):585-586

In addition to the well-defined phenolic estrogens in human pregnancy urine there appears to be another estrogenic substance which is a neutral non-ketonic compound.  相似文献

漳河水库入库洪水抗误差预报方案     

雒文生  易赛莉  俞淞  李莉红  张青  宋星原 《中国农村水利水电》2004,(12):47-50

漳河水库由观音寺水库和鸡公尖水库通过半天然明槽相互连通组成，因受库水位观测、明槽输水计算、动库容计算误差等的复杂影响，以往多次建立的洪水预报方案均未达到可供应用的水平。在分析漳河水库入库洪水误差产生特点的基础上，通过建立抗误差产汇流预报模型和自适应实时校正技术，使漳河水库洪水预报方案平均确定性系数达91.09%，洪峰合格率达100%，峰现时间合格率达90.91%；观音寺水库洪水预报方案的平均确定性系数达90.63%，洪峰合格率达100%，峰现时间合格率达100%，终于建立了达到甲等水平的漳河水库洪水预报应用方案。  相似文献   

Primary and secondary bone tumours in the dog   总被引：1，自引：0，他引：1  

S.-K. Liu  H. D. Dorfman  A. I. Hurvitz  A. K. Patnaik 《The Journal of small animal practice》1977,18(5):313-326

During a 14-year period (January 1962 to December 1975), 394 primary and secondary tumours or tumour-like lesions affecting bones were diagnosed in the dog. The most frequently occurring tumour was osteosarcoma (183, 46.5%), followed by chondrosarcoma (forty-four, 11.2%), squamous cell carcinoma (thirty-nine, 10%), fibrosarcoma (thirty-one, 7.8%), multiple myeloma (fourteen, 3.6%), haemangiosarcoma (fourteen, 3.6%), malignant melanoma (thirteen, 3.3%), synovioma (nine, 2.3%), lymphosarcoma (eight, 2.0%), cartilage analogue of fibromatosis (seven, 1.8%), adaman-tinoma (five, 1.3%), osteocartilaginous exostosis, ossifying fibroma, rhabdomyosarcoma (four each), polyostotic cyst, haemangiomatosis (three each), odontoma, tumoral calcinosis (two each), and osteoma, chondroma, desmoid fibromatosis, and malignant mesenchymoma (one each).
Of these, desmoid fibromatosis, malignant mesenchymoma, and haemangiomatosis have not been previously reported in the dog.  相似文献   

The effect of footrot on body weight and wool growth of sheep   总被引：1，自引：0，他引：1  

DJ MARSHALL  RI WALKER  BR CULLIS  MF LUFF 《Australian veterinary journal》1991,68(2):45-49

Body weight and traits associated with production of wool were measured over a 2-year period between 1985 and 1987 in south-western New South Wales in a flock of Merino wethers experimentally infected with footrot. The disease was allowed to spread freely amongst 150 of the flock but kept at very low prevalence in the remaining 50 by preventive footbathing during transmission periods. Severe, underrunning footrot had a significant adverse effect on body weight, for each year of the trial. Body weight was most severely reduced at times of the year when footrot was spreading among animals and lesions were severe. The mean body weight of the infected group at the end of the 2 years of observation was 7.3 kg (11.6%) below that of the control group. Footrot also depressed wool growth, with the mean clean fleece weight of the infected group being 0.4 kg (8%) lighter than that of the controls at each of the 2 annual shearings. There were no consistent differences between the groups for the other wool characteristics measured.  相似文献

Cultures of skin fiibroblasts from a patient with Fabry's disease showed an accumulation of the glycolipid, galactosyl-galactosyl-glucosyl ceramide. Such cells also showed metachromasia on staining with toluidine blue and a markedly elevated acid mucopolysaccharide content.  相似文献   

Individual tumors of multifocal EB virus-induced malignant lymphomas in tamarins arise from different B-cell clones   总被引：10，自引：0，他引：10  

M L Cleary  M A Epstein  S Finerty  R F Dorfman  G W Bornkamm  J K Kirkwood  A J Morgan  J Sklar 《Science (New York, N.Y.)》1985,228(4700):722-724

Cotton-top tamarins were inoculated with sufficient Epstein-Barr virus to induce multiple tumors in each animal within 14 to 21 days. The tumors consisted of large-cell lymphomas that contained multiple copies of the Epstein-Barr virus genome and generated Epstein-Barr virus-carrying cell lines showing no detectable consistent chromosomal abnormality. Hybridization of tumor DNA with immunoglobulin gene probes revealed that each lymphoma was oligo- or monoclonal in origin and that individual tumors from the same animal arose from different B-cell clones. Thus the virus induced multiple transformation events in tamarins in vivo to cause malignant tumors resembling the Epstein-Barr virus-associated lymphomas of patients with organ transplants.  相似文献   

Studies on Immunological Effect and Immunological Mechanism Avian Encephalomyelitis Oil Emulsion Inactivated Vaccine     

CHENG Zi-qiang  ZHAO Zhen-hua  RI Mudema 《中国农业科学(英文版)》2002,1(7):811-815

Oil emulsion inactivated vaccine was prepared by susceptible embryos, with different strains of AEV. Four groups of normal chickens of 2 - 7 days of age were given injections for immunization, respectively. Another group was used as control. This study was expected to evaluate the immunological effect and discuss the immunological mechanism by means of five different experiments, i.e. the agar-gel precipitin test,the isolation of lymphokine, the isolation, purification and analysis of blood serum IgG, embryo-susceptibility test, and clinical and pathological examination. The results of these experiments indicated that oil emulsion inactivated vaccine is safe and effective. The chickens were normal when inoculated with AE strong virus after immunity at 4 and 37 weeks. Immunological mechanism is that the humoral immunity played an important role and celluar immunity exists, but it is not important in the process of the resistance to AEV.  相似文献   

Jejunal incarceration by an omental tear in a dog.     

G Hosgood  M Bunge  M Dorfman 《Journal of the American Veterinary Medical Association》1992,200(7):947-950

A 2-year-old male mixed-breed dog was examined after being hit by a car, and exploratory celiotomy revealed jejunal incarceration through an omental tear. The affected intestinal segment was distended and black, and had small serosal tears. Clinical signs of disease and hematologic, serum biochemical findings during surgery were consistent with concurrent diagnosis of sepsis. The dog responded to supportive treatment and resection of the affected intestinal segment by jejunal end-to-end anastomosis.  相似文献
