Abstract
Mitoxantrone (DHAQ) we studied is a new semisynthetic antitumor drug prepared in China. This paper reports the pharmacokinetic studies of 3H-mitoxantrone in mice by liquid scintillation. The results showed that the decline of radioactivity in the plasma was a biphasic curve after intramuscular and intravenous injection in rats. The adsorption of 3H-DHAQ was ready and complete after intramuscular injection, it was widely distributed in body tissues. The concentration order of various organs was liver greater than intestine greater than kidney greater than lung greater than heart greater than muscles greater than brain. The elimination of the drug was slow, T1/2 was 42.56 h. In 72 h after administration the cumulative excretion of radioactivity in urine was 7% of the total dose, while that in feces was 43%. The main forms of the drug in urine were its metabolites.

Abstract
The author analyzed 728 cataract extractions performed through 4 mm incisions during January 1972 to January 1987. 230 of the operations were done by phaco-emulsification, 320 by lensectomy, and 178 by aspiration. 580 of the eyes were followed up 1-15 years, when 87.8% of the eyes had corrected vision of 0.06 or over, and 48.8% of 0.6 or over. The technical aspect of cataract extraction through a small incision was evaluated and corneal astigmatism thereof discussed.

Abstract
This paper reports clinical observations made during experimental Brugia malayi infection in man. This was induced by 52 infective larvae-carrying mosquitoes, Anopheles sinensis. A monkey, Maccaca mulatta, was inoculated with infective larvae from the mosquitoes infected with nocturnally periodic type of B. malayi from patients. Six months later, the monkey became a microfilaria carrier. Nine days later, the subject was experimentally bitten by mosquitoes infected from biting the monkey, with an estimated delivery of over 200 infective larvae. Seven days after the infection, general (but fluctuating) pruritus developed, followed by lymphadenitis and swelling of the hand and forearm, with a mild pyrexia for nearly 3 months. The eosinophil counts continuously increased. There were four separate attacks of lymphangitis. On day 142, microfilaraemia was first detected. After two more weeks, the subject was treated with a total dose of 15 g diethylcarbamazine (DEC) over 30 days. During this period, 28 small tender subcutaneous nodules appeared on his arms. After treatment, microfilaraemia gradually disappeared and the swelling of his arms improved. Three months later, the eosinophil count of his blood returned to normal but some temporary and scattered small pruritic erythematous patches still persisted over his left forearm. Lymphangitis has not recurred.

Abstract
This paper describes a culture system which supports the formation of B cell and some T cell colonies under serum-free conditions in peripheral blood samples of normal individuals and patients with chronic lymphocytic leukemia (CLL) of B cell type. In this system, serum is replaced by bovine serum albumin, transferrin, cholesterol, insulin and catalase or horseradish peroxidase. In addition, it is necessary to add staphylococcus protein A, mitomycin-treated T cells as feeders and phytohemagglutinin leukocyte-conditioned medium as a source of growth factors. The plating efficiency is greatly enhanced when normal cells are incubated with galactose oxidase prior to plating and when CLL cells are exposed sequentially to neuraminidase and galactose oxidase.

Abstract
This correspondence presents several parallel algorithms for image template matching on an SIMD array processor with a hypercube interconnection network. For an N by N image and an M by M window, the time complexity is reduced from O(N2M2) for the serial algorithm to O(M2/K2 + M * log2 N/K + log2 N * log2 K) for the N2K2-PE system (1 ¿ K ¿ M), or to O(N2M2/L2) for the L2-PE system (L ¿ N). With efficient use of the inter-PE communication network, each PE requires only a small local memory, many unnecessary data transmissions are eliminated, and the time complexity is greatly reduced.

Abstract
A serological mass survey was carried out in Wuzhou City in 1980, 1,136 IgA/VCA-positive persons being followed up for 4 years. Altogether 35 NPC cases were detected, of which 15 (43%) were in stage I and 17 (48.5%) in stage II, early cases (I + II) thus amounting to 91.5%. The detection rate of early cases was 2.9 times higher than in our outpatient clinic. IgA/VCA antibody could be detected 16-41 months prior to clinical diagnosis of NPC. We conclude that, if IgA/VCA-positive individuals are examined routinely once a year, NPC can be detected in the early stages of evolution. The annual detection rate of NPC in IgA/VCA antibody-positive individuals was 31.7 times higher than that of the annual incidence of NPC in the general population in the same age group, while during the 4-year follow-up period the incidence was 7.5 times higher than in the general population for the same age group. These results further indicate that EB virus plays an important role in the development of NPC, and that serological screening and follow-up studies are valuable for the early detection of NPC.

Abstract
Praelolide is a new compound which was isolated out from the gorgonian, Menella praelonga (Ridley), collected from the South Sea of China at Zhanjiang, Guangdong. The molecular formula is C28H35O12Cl. The research result by X-ray diffraction method on the crystal structure is presented. The compound is orthorhombic with space group P2(1)2(1)2, cell dimensions a = 16.936, b = 16.709, c = 10.333 A, and Z = 4. The structure has been solved by direct method and refined to R = 0.055 for 2257 unique observable reflexions by least-squares. The molecule is composed of the major conformational isomer in which the three main rings (a six-membered ring, an eight-membered ring, a six-membered ring) take separately the form of chair-chairboat-chair, a five-membered actone ring, a C1 substitution, 4 acetate groups, and a three-membered epoxide ring. The absolute configuration of the molecule has also been determined by statistics (R factor ratio R = 1.012) and Bijvoet pairs observation. For 30 pairs of the greatest anomalous contributions the residuals are R'(+) = 0.057 for the first enantiomorph and R'(-) = 0.005 for the second one, so the latter should unambiguously correspond to the absolute configuration of the molecule.
