Intrapleural and intravenous Corynebacterium parvum in patients with resected stage I and II non-small cell carcinoma of the lung

Summary A prospective randomized trial compared the administration of intrapleural plus intravenous Corynebacterium parvum (C. parvum) versus placebo in patients with resected Stage I and Stage II non-small cell bronchogenic carcinoma. Treatment consisted of 7 mg C. parvum injected into the pleural space and 7 mg C. parvum intravenously once between days 6 and 12 postoperatively and 7 mg intravenously every 3rd month during the 1st year. Intrapleural administration of 35 cc of saline served as the placebo and the flush after intrapleural C. parvum.Of the 303 patients entered into this study, 286 were evaluable, with an average follow-up time of 3.5 years. More complications, especially fever, were observed in patients receiving C. parvum. A fever greater than 38 °C was observed in 9% of the patients assigned to placebo and 76% of the patients assigned to C. parvum. There was no significant difference between the treatments with respect to disease-free interval or survival.M. Kaufmann, J. Stjernswärd**, A.

正常月经周期妇女卵泡液中激素水平的变化

本文测定了24例正常月经妇女在不同时相、不同大小卵泡的卵泡液中雌二醇(E_2)、孕酮(P_0)、雄烯二酮(A)、睾酮(T)、卵泡刺激素(FSH)、黄体生成素(LH)和催乳素(PRL)的含量,并分析其与外周血中相应激素浓度的关系。测定结果显示:小卵泡的卵泡液中E_2、Po,FSH,LH水平低于大卵泡中水平,而A和T水平则相反。排卵前大卵泡中E_2(9815nmol/L),P_0(3316nmol/L),FSH(1.34IU/L)和LH(3.9lIU/L)达最高值。A(280nmol/L)和T(137nmol/L)却较小卵泡中水平低(相应为692nmol/L和176nmol/L)。PRL水平在大小卵泡中无显著性差异。卵泡液中甾体激素水平高于外周血7—20.000倍,FSH、LH水平为外周血的10—80％,PRL水平为60％—3倍。     

Search for the possible role of ‘immunotherapy’ in operable bronchial non-small cell carcinoma (stage I and II): A phase I study with Corynebacterium parvum intrapleurally

Summary The possibility of giving C. parvum intrapleurally (i.p.) was investigated. C. parvum was given post-operatively either i.p. only or i.p. and intravenously (i.v.) simultaneously. The dose varied from 0.1–10 mg i.p. All patients had been operated for a bronchial carcinoma. Results: (1) Subjective complaints of either dyspnoea, thoracic pain, chills or nausea occured in 31 of 63 patients. No clear dose relation was found. A feeling of discomfort and fever could occur for another 3–4 days after the above more acute symptoms had disappeared. (2) Increased fever (0.5° C) occurred in 71% of the patients injected i.p. only. (3) No anaphylactic reaction was observed. (4) Increased total white blood cell counts (<20%) occurred in 38 patients. The WBC increase was mainly due to higher number of neutrocytes and granulocytes. Total lymphocyte, monocyte, eosinophilic, and basophilic granulocytes values per mm³ circulating blood remained unchanged, except at the dose of 7 mg C. parvum i.p. when monocyte values were increased significantly from 576±247 to 1100±578/mm³. (5) Moderate to severe effusions were observed radiologically in three patients after C. parvum intrapleurally.The study group is: M. Kaufmann, J.

用PO4细胞为靶细胞检测人血清中Epstein-Barr病毒IgA/MA抗体以诊断鼻咽癌

近年来,常用未经丙酮固定的、由丁酸和巴豆油激活的B95-8细胞或P3HR-1细胞为靶细胞,检测人血清中EB病毒IgA/MA抗体以早期诊断鼻咽癌,效果良好。但由于B95-8细胞含有多种EB病毒抗原,不能用丙酮固定,需多次离心沉淀,在浮悬状态下检测,技术比较复杂。     

天然来源抗肿瘤化合物作用于MAPK通路的机制

天然来源抗肿瘤活性产物是抗肿瘤药物先导化合物的重要资源。促分裂原活化蛋白激酶(MAPK)通路是细胞内重要的信号转导系统,可以调节细胞的生长、凋亡、黏附、迁移等过程,继而影响肿瘤的发生、发展、侵袭、转移,是潜在的抗肿瘤药物作用靶点之一。本文将对天然来源化合物作用于MAPK信号通路的靶点分子及生物效应进行阐述,为肿瘤的化学预防及治疗提供启发。     

Variation in cancer risks, by mutation position, in BRCA2 mutation carriers

Cancer occurrence in 164 families with breast/ovarian cancer and germline BRCA2 mutations was studied to evaluate the evidence for genotype-phenotype correlations. Mutations in a central portion of the gene (the "ovarian cancer cluster region" [OCCR]) were associated with a significantly higher ratio of cases of ovarian:breast cancer in female carriers than were mutations 5' or 3' of this region (P<.0001), extending previous observations. The optimal definition of the OCCR, as judged on the basis of deviance statistics, was bounded by nucleotides 3059-4075 and 6503-6629. The relative and absolute risks of breast and ovarian cancer associated with OCCR and non-OCCR mutations were estimated by a conditional likelihood approach, conditioning on the set of mutations observed in the families. OCCR mutations were associated both with a highly significantly lower risk of breast cancer (relative risk [RR] 0.63; 95% confidence interval (95% CI) 0.46-0.84; P=.0012) and with a significantly higher risk of ovarian cancer (RR = 1.88; 95% CI = 1.08-3.33; P=.026). No other differences in breast or ovarian cancer risk, by mutation position, were apparent. There was some evidence for a lower risk of prostate cancer in carriers of an OCCR mutation (RR = 0.52; 95% CI = 0.24-1.00; P=.05), but there was no evidence of a difference in breast cancer risk in males. By age 80 years, the cumulative risk of breast cancer in male carriers of a BRCA2 mutation was estimated as 6.92% (95% CI = 1.20%-38.57%). Possible mechanisms for the variation in cancer risk are suggested by the coincidence of the OCCR with the RAD51-binding domain.
