    While paying a due attention to the change in heat-coagulability of the serum of cancer patient, the author estimated the fluctuations of heat-resistant non-coagulating substance in the serum with polarography, and applying it on cancer diagnosis, studied the relationship between anemia, the leucocyte count, the rate of erythrocyte sedimentation, and the liver function In addition, with the cases with gastric cancer the author studied the relationship between the fluctuations above mentioned and various supposed to exert in fluences on the height of the polarographic wave; and obtained the following results: 1. In the patients with gastritis, gastric and duodenal ulcers the polarography gives the negative cancer reaction in 100 per cent. 2. Gastric cancer patients show the positive cancer reaction in the polarograph in 92.9 per cent. 3. In the patients with malignant tumors other than gastric tumor the cancer reaction is positive in 79.2 per cent. Negative cases are found frequently in the cases with malignant tumors such as those of mammary glands and thyroid glands not belonging to the digestive system. 4. In various diseases other than malignant tumors (excepting gastric cancer) 73 per cent of them show negative cancer reaction, but positive raction can be frequently encountered in tuberculous disease, occlusion ileus, extensive disorders in the digestive system, and diseases of the reticulo-endothelial system. 5. No direct relationship can be recognized between the heat-resistant non-coagulation reaction of serum (Tsuda-Okujima's method) and the polarographic cancer reaction. 6. Neither any direct relationship can be observed between this cancer reaction and anemia, the leucocyte count, the plasma protein content, the rate of erythrocyte sedimentation, the liver functon, and jaundice. 7. As for the cases with gastric cancer: a. No relationship can be recognized between existence or non-existence of free hydrochloric acid in gastric juice and the height of polarographic wave. b. The greater the size of gastric cancer the higher is the height of the polarographic wave. c. There is no relationship between the site of gastric cancer and the height of polarographic wave. d. In the macroscopic classification (Borrmann) of tumors, it has been found that the height of polarographic weve increases along wirh the progress of the disease from type I to type IV. e. In those histologically suggesting undifferentiation and a higher degree of malignancy, the height of the polarographii wave is higher. f. Summarily viewing the course of progress in the symptoms of gastric cancer, as the disease progresses from the early stage to the terminal stage, the height of polarographic wave becomes higher

    It is well known that the serum of cancer pationt possesses a specific coagulability to heat. By estimating heat-resistant non-coagulating substances of the serum in the rabbits previously injected with cancer tissue extract and benign gastric mucosa extract by Tsuda-Okujima's method the author pursued changes in these substances as well as inves tigated the relationship between the erythrocyte count, leucocyte count, and plasma protein content. The following are the results. 1. Rabbits given intravenous injection of cancer tissue extract to the ear-lobe show marked differences from those similatly injected with benign mucosa extract. 2. Observation for a long period of time is possible when extract is given intraperitoneal, and those injected with cancer tissue extract show a marked increase in heat-resistent non-coagulating substances when compared with those injected with benign mucosa extract. 3. There is a certain relationship between the change of the erythrocyte count and that of the hemoglobin content, namely, between the degree of anemia and the change of heatresistant non-coagulating substances in serum, but in the strict sense it is not a parallel relationship. 4. Between the leucocyte count and heat-resistant noncoagulating substance not any relatinoship can be recognized. 5. No completely parallel relationship can be recognized between the plasma protein content and heat-resistant noncoagulating substance. 6. Likewise no parallel relationship can be seen between tyrosine excreted in urine and heat-resistant non-coagulating substance

Lett. 62, 3250 (1993) and may be found at https://doi.org/10.1063/1.109089.Multiple quantum well structure consisting of alternating layers of organic 8‐hydroxyquinoline aluminum (Alq3) and aromatic diamine (TPD) has been grown by organic molecular beam deposition. The multiple quantum well structure was determined by x‐ray diffraction, optical absorption, and photoluminescence. Photoluminescence peak of Alq3 shifts to higher energy with decreasing layer thickness, suggesting a quantum size effect. An electroluminescent diode has also been fabricated by using Alq3/TPD multiple quantum well structure

The EL emission from the multilayer structure shows spectral narrowing and the emission energy has been observed to shift to higher energy compared with that in the monolayer structure. Mechanism of spectral narrowing and the emission energy shift in the diode with the multilayer structure have been discussed

Emission colors could be selected either blue or red by changing the polarity of the applied voltage. By driving with an ac biased electric field, both emission colors were observed and the intensity ratio of each emission color was modulated by the frequency of the applied ac field
