An experimental study of 300 mice exposed to pitch(3 gm.dissolved in 10 ml.of 80% benzene solution)obtained from 4 different sources,name- ly Anshan coal-tar pitch,Yu-men petroleum pitch,Dairen petroleum pitch or commonly known as Russian crude oil and the Asia Oil Company, USA,was carried out over a period of 350 days. From the beginning a group of these experimen- tal animals was exposed to artificial sun-ray for 2 hours a day.The results of our experiment indicate that pathological changes of different degrees of severity,such as chronic dermatitis and tumor formation,were the commonest effect of pitch on skin both in the exposed and non-ex- posed groups while the control group(exposed to 80% benzene only)showed only slightly acute dermatitis. The pathological changes as observed both in gross appearances and histological findings are given in detail. The course of tumor formation as found in both the exposed and the non-exposed groups may be classified in the order of time sequence as benign squamous papilloma,malignant squamous papilloma and finally squamous-celled carcinoma; also a few cases of sarcoma and a few cases of so- called“Myoblastoma”. Through the action of photosensitivity to the exposed group,the prolongation of the latent period of tumor formation,the effectiveness in the development of dermatitis and malignant changes in tumors were clearly observed in the process of the pathological changes. The relative potency of the carcinogenic pitch obtained from the above sources has been calculated by means of the statistical analysis of both the incidence and the length of time for the development of the cutaneous tumors.

(一)四种来源不同的沥青(鞍山煤焦油沥青、西北玉门石油沥青、大连石油沥青、和美国亚细亚公司石油沥青)经涂抹小白鼠的实验证明具有引起皮肤各种的病理变化的作用。其中包括慢性渗出性皮炎;慢性炎性上皮结缔组织增生;良性皮肤乳头状瘤;皮肤鳞状细胞癌。此外也引起了少数的肉瘤和“肌母细胞痛”。皮肤瘤发生的潜伏期由62天至406天不等。(二)光感作用可以加剧及加速煤焦油沥青皮肤炎的进展,和发炎皮肤的角化现象。至于对沥青致癌作用本实验未能证实其有显著的影响。(三)根据四种来源不同的沥青所引起皮肤良性与恶性病变的发病率和潜伏期的长短,可将其毒性的强弱顺序排列如下:(1)鞍山煤焦油沥青,(2)美国亚细亚公司石油沥青,(3)大连石油沥青(苏联原油),(4)西北玉门石油沥青。即煤焦油沥青毒性远较石油沥青为强。国产石油沥青的毒性较外产石油沥青的毒性为弱。

In this article, we described a procedure of isolation of basic proteins from brain glioma and stomach cancer, and presented the results of detecting tumor antigenicity by means of a macrophage electrophoretic mobility (MEM) test with lymphocytes isolated from 623 subjects,which consisted of 95 normal persons, 167 cases of brain tumor 65 cases of stomach cancer, 161 cases of miscellaneous malignant tumor, 25 cases of benign tumor and 120 cases suffering from other diseases.Using"glioma basic protein" (GBP)...

In this article, we described a procedure of isolation of basic proteins from brain glioma and stomach cancer, and presented the results of detecting tumor antigenicity by means of a macrophage electrophoretic mobility (MEM) test with lymphocytes isolated from 623 subjects,which consisted of 95 normal persons, 167 cases of brain tumor 65 cases of stomach cancer, 161 cases of miscellaneous malignant tumor, 25 cases of benign tumor and 120 cases suffering from other diseases.Using"glioma basic protein" (GBP) as an antigen, the incidence of positive reactions in the MEM test was 1.2% (1/85) in normal persons, 92 % (145/158) in brain tumors, 94% (16/17) in stomach cancers,91.1% (92/101) in miscellaneous malignancies, 20% (5/25) in benign tumors and 9.1% (8/88) in the rest cases. When using "stomach cancer basic protein"(SBP)as antigen,the positive incidence was found as follows :0% in 10 normal persons, 89% (8/9) in brain tumors, 95% (36/38) in stomach cancers, 92% (55/60) in miscellaneous malignancies and 6.3% (2/32) in the others.The above results demonstrated that more than 90% lymphocytes from patients with brain tumor, stomach cancer, or miscellaneous malignancies, when allowed to react with GBP or SBP, displayed a slowing effect on MEM while that from normal persons or non-tumor patients more than 90% did not show such an effect. Our results are broadly in accord with the observations of Field et al but contrary to that of Forrester et al.

本文介绍了从人脑胶质瘤和胃癌中提取硷性蛋白的方法,并用总数为623人的淋巴细胞(包括健康人95人、脑瘤167例、胃癌55例、其他部位癌肿161例、良性肿瘤25例以及非肿瘤性疾病120例),对以上两蛋白制剂的肿瘤抗原性进行巨噬细胞电泳试验(MEM)的检查。 用脑胶质瘤硷性蛋白(GBP)作为抗原时,MEM试验的阳性率为:正常人为1.2%(1/85)、脑瘤为92%(145/158)、胃癌为94%(16/17),其他部位癌症为91.1%(92/101)、非肿瘤性疾病为9.1%(8/88)、良性肿瘤为20%(5/25)。当用胃癌硷性蛋白(SBP)作为抗原时,其阳性率为:正常人为0%(0/10)、脑瘤为89(8/9)、胃癌为95%(36/38),其他部位癌症为92%(55/60)、非肿瘤性疾病为6.3%(2/32)。 上述结果表明90%以上脑瘤、胃癌及其他部位癌症病人的淋巴细胞,当接触GBP或SBP时,有使巨噬细胞电泳减缓的作用;而在相同条件下90%以上的正常人及非肿瘤性疾病患者无此作用。以上结果初步看来与Field等人所观察到的结果相一致,而与Forres-ter等人的结果却相反。

In part Ⅰ of this ariticle, 61 cases from 10 kinds of animals malignant neoplasms were reported by the authors.these cases were examined from 668 animals in kwangtung in the past three years.They were sow's nasopharyngeal carcinoma (NPC),sow's carcinoma of nasal cavity and sow's carcinoma of accessory nasal siuneses, hen's esophugeal carcinoma (Squamous cell carcinoma in situ), hen's lymphocytic leukemia, hen's leukosarcoma ,hen's ovarian carcinoma and hen's fibrosarcoma,deer's carcinoma of vulva,bovine and...

In part Ⅰ of this ariticle, 61 cases from 10 kinds of animals malignant neoplasms were reported by the authors.these cases were examined from 668 animals in kwangtung in the past three years.They were sow's nasopharyngeal carcinoma (NPC),sow's carcinoma of nasal cavity and sow's carcinoma of accessory nasal siuneses, hen's esophugeal carcinoma (Squamous cell carcinoma in situ), hen's lymphocytic leukemia, hen's leukosarcoma ,hen's ovarian carcinoma and hen's fibrosarcoma,deer's carcinoma of vulva,bovine and pig's lymphos.urcorna.Some of these tumors (such as pig's NPC and carcinoma of sphenoidalissiuns) have not been reported in the world literature, and the discovery of sow's NPC in Kwangtung area is of particulary importance because this malignant neoplasm is prevalent among inhabitants in this area.In part Ⅱ of this article,the authors report some other tumors examined from the same 668 animals.There are 63 cases from 12 kinds of tumors(G cases from 4 kinds belonging to benign tumors and 57 cases from 8 kinds belonging to malignant tumors) .They are primary liver cancer (sow, duck and hen),carcinoma of oral cavity (sow), carcinoma of colon (pig),carcinoma of small intestine(hen) ,fibroma(bovine and pig), papilloma of bladder (bovine),carcinoma of breast (dog and pig),rotundo-cell sarcoma (fish) ,Marek's disease (chicken),carcinoma of kidney (hen) and teratoma(bovine).The sow's carcinoma of oral cavity,pig's carcinoma of colon,hen's carcinoma of small intestine, pig's carcinoma of breast and hen's carcinoma of kidney arc examined in China for the first time, The primary liver cancer of, the animal has its signifacance for the analysis of the etiology of this kind of tumor in man. The cotundo-ccll sarcoma examined from fish shows a wide distribution of the neoplasm in nature.The authors also discribe the clinical characteristics, macroscopic and microscopic appearances,and discuss the epidemiology and etiology of these neoplasms.

作者报告了在广东省各地于668例动物中检出了一批肿瘤,其中10种肿瘤计64例已整理于本文的第一报中,这64例全部均为恶性肿瘤,其中比较重要的肿瘤有鼻咽癌、鼻腔癌、副界窦癌和食管癌等。涉及的动物有猪、牛、家禽和野生动物。 在本文(第二报)中,作者继续报告了从这688例动物中检出的第二批肿瘤计12种共63例(恶性肿瘤8种57例,良性肿瘤4种6例),受这些肿瘤侵害的除哺乳动物和卵生动物外,还有鱼类。其中比较重要的肿瘤有原发性肝癌、小肠癌、结肠癌、肾癌、口腔癌和乳腺癌等。作者指出,在人群原发性肝癌发病率很高的广东省各地,于各种动物中相应地发现了这种恶性肿瘤,有助于对肝癌的流行病学与病因学的深入研究。肾癌、口腔癌、小肠癌、结肠癌和乳腺癌这些罕见的肿瘤首次在我国检出,有重要的研究价值。在鱼类首次检出了圆形细胞肉瘤,反映了动物间肿瘤的分布的日益广泛。作者报告了上述这些肿瘤的临床症状、病理形态特征和其他有关资料,并对其中的一些肿瘤的流行病学和病因学问题进行了讨论。
