Abstract
40 cases of breast tumor (cancer group 20 cases, benign tumor group 20 cases) hospitalized from October, 1986 to April, 1987 were investigated by interview, HAMD, SCL-90 and so on. Results showed that 10 cases met diagnostic criteria of organic affective syndrome defined by DSM-III. The morbidity of depression among all cases was 25 per cent, but the morbidity of depression in breast cancer group was higher than in benign tumor group. Causes of depression in breast cancer were analysed. Authors consider that causes of depression are not relating to operation on breast, but probably relating to biological and psychosocial factors.

Abstract
A general method for the precise evaluation of the integrated effective emissivity of a diffuse frustrum-cone cavity is formulated. The mathematical expressions derived can be applied to calculate precisely the integrated emissivity of, or the irradiance of a detector from, any practical axisymmetric cavity with circular symmetry. Some typical values of integrated emissivity are presented for cylinders, cylindro-cones, double cones, and cylindro-inner-cones, and comparisons between such cavities are made.

Abstract
Three indolic alkaloidal glucosides were isolated from the polar fraction of the stems of Nauclea officinalis. Two are new, named naucleoside (Ia) and nauclecosidine (IIa) and the other is a well known alkaloid, vincoside lactam. The structures of Ia and IIa were elucidated on the basis of spectroscopic data (IR, MS, HNMR and CNMR) and chemical evidence.

Abstract
The temporal and spatial expression of the period gene of Drosophila melanogaster has been analyzed by examining the expression of a per beta-galactosidase fusion gene in transformants and by in situ hybridization experiments with wild-type flies. Several strains of Drosophila melanogaster, transformed with the fusion gene, have been generated. The gene is active in mid-late embryos in the midline of the nervous system. Thereafter, beta-galactosidase activity is undetectable until the pupal stage when the prothoracic gland-corpora allata and the optic lobes are beta-galactosidase positive. In adults a surprisingly large number of tissues stain positively, including antennae, proboscis, eyes, optic lobes, cells of the central brain, cells of the thoracic ganglia, gut, Malpighian tubules, and ovarian follicle cells. The temporal pattern of expression agrees well with previous estimates made from developmental Northern blots with RNA extracted from wild-type animals. We suggest that many of the tissues that express the per gene contain their own intrinsic oscillator activity.

Abstract
An ascitic subpopulation (Anip) was isolated from human lung adenocarcinoma cell line AGZY-83-a through serial intraperitoneal passages in nude mice. Anip manifested a much higher metastatic potential than the parent line. Spontaneous lung metastases occurred in 95% of the mice xenografted intraperitoneally, and the diffuse pattern of the metastases in the lung was very impressive. Anip also differed more or less from the parent line in morphology, growth, rate, electrophoretic mobility, platelet aggregating activity and noticeably in the chromosome histogram. The present model may be used in the study of tumor invasion and metastasis, as large amounts of well dispersed metastatic human carcinoma cells could be reproduced by ascites and much information about the biology of invasion and metastasis of human tumor cells in nude mice could be obtained.

Abstract
Effect of sodium selenite on chromosomal aberration of V 79 cells induced by MNNG and MNU was studied. Na2SeO3 alone, at the concentration of 10(-7)-10(-4) M, increased the incidence of chromosomal aberration. However, Na2SeO3 at 10(-7)-10(-5) M, having been preincubated with the cells for 4 hours, could reduce the number of cells with chromosomal aberration induced by MNNG. Na2SeO3 at 10(-7)-10(-4) M inhibited mutagenic activity of chromosomal aberration induced by MNU. The same inhibition was observed even sodium selenite was added to the medium simultaneously with this carcinogen. The results indicate that sodium selenite alone, at the concentration range used in this experiment, is an aberration-inducing agent. But when combined with the carcinogen, anti-cancer effect is obtained.

Abstract
Determination of SCE frequency, chromosomal aberration and micronucleus rate of cultured peripheral lymphocytes in 32 patients with lung cancer, 33 miners and 40 non-mining workers in Yunnan Tin Mine was carried out. The results showed that the cancer patients had higher SCE incidence, chromosomal aberration and micronucleus rate, the non-mining workers had the least and miners on an intermediate level. There was a significant difference of SCE, chromosomal aberrations and micronucleus rate between patients and non-mining workers (P less than 0.05-0.01). We also found that miners had a significant higher SCE and chromosomal aberration rate but not micronucleus rate as compared with the non-mining workers. We proposed that some carcinogens present in the Yunnan Tin Mine be responsible for the genetic damages in the miners. Chemical drugs may be considered to contribute to the genetic damage in cancer patients who had a tendency toward an increased SCE, chromosomal aberration and micronucleus rate as compared to the miners, though without reaching a statistical significance. We suggested that combination assay of SCE with chromosomal aberration or micronucleus be an useful index for screening of the high risk population and monitoring the chemical drug prevention of lung cancers in Yunnan Tin Mine.

Abstract
For 8 wk 5 groups of 10 men each were given 0.5 g/day DL-methionine, 150 micrograms Se/day as sodium selenite with or without methionine or 150 micrograms Se/day as selenomethionine with or without methionine. Twenty subjects received placebo as controls. Initially plasma Se rose more rapidly than RBC Se. Increases in Se levels were significantly greater with selenomethionine than with the selenite supplement. In the placebo and methionine supplemented groups neither plasma nor RBC Se varied significantly over the course of the study. Supplementation with selenium resulted in marked increases in plasma and RBC GSH-Px within 2 and 4 wk, respectively. Plasma and RBC GSH-Px activity did not differ significantly between Se-supplemented groups. These studies suggest that selenomethionine-Se was more effective in raising plasma and RBC Se than was selenite-Se. Methionine supplements may increase the bioavailability of selenium in severely deficient subjects.
