Chronic myelogenous leukemia in the monosomic cell line of a fertile turner syndrome mosaic (45,X/46,XX)

Malignancy in patients with constitutional chromosome abnormality is of interest not only because it permits insights into the relationship between chromosome abnormality and cancer, but also because it provides opportunities to address such questions as the clonality and evolution of tumors. We report Ph¹-positive chronic myelogenous leukemia (CML) in a 50-year-old mosaic (45,X/46,XX) Turner syndrome patient whose leukemia was restricted to the monosomic cell line. Our extensive cytogenetic studies of this patient demonstrated that non-leukemic normal cells persisted in the marrow and were able to proliferate during a period of temporary suppression of the leukemic clone following aggressive treatment.     

The familial prevalence in second-degree relatives of patients with anxiety neurosis (panic disorder)

A family history study of second-degree relatives of 19 patients with anxiety neurosis (panic disorder) and 19 controls showed a morbidity risk of 9.5% among the former compared with 1.4% among the latter. These risks were approximately half those found among first-degree relatives. Female relatives were at higher risk for anxiety neurosis. The risk for other psychiatric illnesses did not differ between the relatives of anxiety neurosis and controls.     

Monoclonal antibody identification of mononuclear cells in endomyocardial biopsy specimens from a patient with rheumatic carditis

A 17-year-old woman with rheumatic carditis underwent endomyocardial biopsy both prior to and following treatment with prednisone and aspirin. Frozen sections from the endomyocardial biopsy specimens were studied with monoclonal antibodies by an indirect immunofluorescence technique to define the composition of the inflammatory infiltrate in the myocardium and to determine whether the composition of the infiltrate is distinctive and diagnostically useful. The specimen from the initial biopsy contained a heterogeneous infiltrate composed of T lymphocytes, macrophages, B lymphocytes, and mast cells. T lymphocytes predominated, and the ratio of T-helper to T-cytotoxic/suppressor cells was 2.0. Following treatment the overall cellularity of the infiltrate was diminished, but the infiltrate remained heterogeneous; T cells predominated, and the T-helper to T-cytotoxic/suppressor ratio was reversed, to 0.59. The composition of the inflammatory infiltrate in this case of rheumatic carditis distinguishes it immunologically from other "idiopathic," presumably virus-associated, forms of myocarditis.

实弹射击考核对不同特质焦虑新兵T淋巴细胞亚群及ACTH的影响

目的：研究急性应激对不同特质焦虑新兵的T淋巴细胞亚群及ACTH的影响。方法：状态一特质焦虑问卷（STAI）将新兵分成高、低特质焦虑组各16人。用流式细胞仪及ELISA测定被试基础期（打靶前4d）、应激期（打靶时）、恢复期（打靶后5d）的CD4^＋、CCD8^＋及ACTH浓度。结果：①高特质组3个时期的CD4^＋、CD4^＋／CCD8^＋比值均低于低特质组。CD8＋高于低特质组；高特质组应激期CD4^＋显著下降（P〈0．05）、CD4^＋／CCD8^＋比值与恢复期有显著差异（P〈0．01）．而低特质组仅应激期CD4^＋定量与恢复期有显著差异（P〈0．01）。②实弹射击前、中、后的ACTH浓度，高特质组变化呈极显著差异（P〈0．001），而低特质组应激期与基础期呈显著差异（P〈0．05）。结论：①急性应激影响新兵的CD4^＋、CCD8^＋及其比值，其程度与特质焦虑有关。②应激时高特质组ACTH浓度下降显著大于低特质组，且随应激源消除不易恢复。

Growth of diploid cells from breast cancers

Cell cultures were derived from normal and cancerous breast tissues and from metastases by methods that selected for relatively adherent epithelial aggregates. Karyotypic analyses of first or second passage cultures yielded predominantly normal diploid cells. Nonclonal aberrations were more common in tumor-derived than in normal cultures. Three of the cultures that originated from metastases were characterized by abnormal clones. These results support observations based on DNA content, which indicate that a considerable fraction of breast cancers are composed predominantly of diploid cells. They differ greatly from chromosomal findings in long-term cultures of tumor effusions and thus emphasize the karyotypic diversity that can be found in tumors from a single tissue of origin--the breast.
