Abstract
An eigenvalue equation is derived for stratified metallic optical slab waveguides with any number of layers. The equation is solved using the numerical zoom analysis (NZA) method. The analysis is applied to various metallic optical slabs and the propagation characteristics of the guided waves are determined, which may be useful for optimizing the design parameters. It is found possible, with proper optimization, to design a polarizer having hundreds of decibels of extinction ratio at. the cost of a fraction of a decibel of insertion loss. Examples of optimizations with respect to wavelength, relative refractive indices, core/clad geometries, etc. are demonstrated for slabs with single or double metal layers. Guidelines for determining the metal film thickness have been formulated and tabulated for many useful metals.

Abstract
Several SV40 transformed REF52 cell lines were found to accumulate 5 to 10 times more cholesteryl esters compared to their parent line REF52 when cultured in 10% serum. Under this culture condition, the cholesteryl ester to phospholipid ratio was 0.4:1 and 2.0:1 to 3.8:1 for normal and SV40 transformed cells, respectively. The mechanism underlying cholesteryl ester accumulation in SV40 transformed lines was investigated. We found that 1) the rate of the de novo cholesterol and cholesteryl ester synthesis was roughly equal in normal and transformed derivatives; 2) the accumulation of cholesteryl esters in the transformants would not occur when cultured in lipoprotein-deficient medium and reappeared upon their return to low density lipoprotein-containing medium; 3) the transformants expressed twice as many low density lipoprotein receptors and were less sensitive to LDL-induced receptor down regulation compared to their nontransformed counterparts. The results indicate that SV40 transformed lines exhibited an accelerated lipid uptake from the culture medium due to an altered regulation of low density lipoprotein receptor activity.

Abstract
This study was undertaken to determine whether the measurement of CA125 could effect an early diagnosis and a method for monitoring the course of gynecologic tumors. CA 125 in serum of 195 patients, including 15 apparently healthy women; 39 benign gynecologic tumors; 2 borderline ovarian tumors; 139 malignancies were measured by CENTOCOR cancer antigen 125 kits. Diagnosis of all patients was confirmed by pathology. None of the healthy women; 10% of benign tumors; 78% of epithelial ovarian cancers; 31% of endometrial adenocarcinomas and one out of five adenocarcinoma of uterine cervix had CA 125 level over 65 U/ml. In addition, 23 cases of ovarian cancer were monitored serially up to 9 months. In more than 80% of these patients, CA 125 levels were correlated with the regression or progression of the disease. The significance of this assay for early diagnosis and monitoring the course of ovarian cancer is discussed. It is considered that CA 125 is a promising and useful antigenic marker for monitoring the course of ovarian cancers.

Abstract
Different responses of spinach and kidney bean plants to various concentrations of NO(2) in the light and in the dark were shown. Spinach is more resistant than NO(2) than kidney bean. It is not only due to its greater tolerance to NO(2)(-) accumulated in leaves, but also to its stronger ability to metabolize NO(2)(-). The injury of spinach induced by the exposure to high concentration NO(2) in the light was not caused by the accumulation of NO(2)(-), but concerned the large amount of accumulated NH(3). The primary causes of NH(3) accumulation were that the activity of nitrite reductase was not affected by the fumigation on the one hand, and the activities of glutamine synthetase and glutamate synthase were inhibited on the other.

Abstract
This paper summarizes data obtained during a screening program involving 11,563 persons from the Silk Road region in China. The mean incidence of thalassemia is 1.62% with an increase from east to west. The incidence in the Hui population (3.01%) is higher than in Kazaks (2.92%), and in Uygur (2.22%). The Han population also has a higher incidence (0.98%) than seen for other regions in Northern China. The thalassemias observed are classified into seven groups; beta-thalassemia accounts for 89.48% of the total, and alpha-thalassemia for 10.52%.

Abstract
62 patients with advanced epithelial ovarian adenocarcinoma (37 stage III, 4 stage IV and 22 recurrent lesions) were treated in our hospital from 1977 to 1981, 38 patients underwent surgery. 25 with inoperable tumor initially received preoperative chemotherapy (VCF protocol: vincristine + cyclophosphamide + fluorouracil chiefly) followed by surgery. The response rate of chemotherapy was 48%. Apart from 1 progressive tumor during chemotherapy, 24/25 were explored. There were 10/24 with residual tumor less than 2 cm in diameter, giving a resection rate of 41.7% as compared with the resection rate of 42.1% (16/38) in the operation group. It is shown that the preoperative chemotherapy improves the resection rate. 44 patients received postoperative chemotherapy and 12, radiotherapy combined with chemotherapy or radiotherapy only. The overall 2.3 and 5 year survival rates of these 63 patients were 39.7%, 31.7% and 23.8%. The 2 and 3 year survivals were 41.9% and 32.3% in 31 patients with postoperative chemotherapy using VCF protocol. The results indicate that VCF protocol is effective for advanced epithelial ovarian cancer, especially patients with residual tumor less than 2 cm in size. Chemotherapy with more than 3 courses has better effect.
