Abstract
It has been found that the effects of opiates and opioid peptides on RVD are of two types. Compounds of the first type such as Etor, Eton, fentanyl and prodine derivatives, Met- and Leu-Enk and DADL are biphasic in nature. At lower concentrations (10(-8)-10(-5) M) they have inhibitory effects and at higher concentrations (10(-5)-10(-4) M) they are excitatory. Compounds of the second type, such as Mor, benzomorphan derivates, Cyc and SKF and the antagonist Nx have virtually no or only weakly inhibitory effects but may antagonize the inhibitory effect produced by the first group of compounds at lower concentrations. MC belongs to the second type, but it cannot antagonize the inhibitory effect of beta-End. The results are discussed in terms of multiple receptors, the high and low affinity binding sites, and the interrelationship between receptors.

Abstract
5-Oxo-L-prolinase catalyzes a reaction in which the endergonic cleavage of 5-oxo-L-proline to form L-glutamate is coupled to the exergonic cleavage of ATP to ADP and Pi. In the present research, the enzyme present in a strain of Pseudomonas putida isolated from soil by enrichment culture was found to be composed of two protein components. Neither component alone could catalyze the 5-oxoprolinase reaction, but the reaction was effectively catalyzed when they were mixed. One component (A) exhibited 5-oxo-L-proline-dependent ATPase activity indicating that Component A can interact with both ATP and 5-oxo-L-proline. The other component (coupling protein; B) does not exhibit ATPase activity nor is there evidence that it binds 5-oxo-L-proline. The findings are consistent with (but do not prove) the hypothesis that the Component A catalyzes an initial step in the reaction which involves 5-oxoproline and ATP, such as phosphorylation of 5-oxoproline. The coupling protein (B) may function as a catalyst that converts a phosphorylated form of 5-oxoproline to glutamate, or it might alter the conformation of Component A so as to facilitate the reaction.

Abstract
Mitochondrial DNA of the liver from Peking duck was cleaved by restriction endonucleases EcoRI, BamHI, PstI and BglI into 1, 2, 4 and 5 fragments, respectively, while the BglII was without any cleavage. The restriction map of this mtDNA was constructed by measuring the length of restriction fragments using both electrophoresis analysis and electron microscopy. The position of D-loop and the direction of replication of the mtDNA were also determined.

Abstract
Serological mass surveys were carried out in Zangwu County, China, using an immunoenzymatic test. 3,533 persons were found to have Epstein-Barr virus (EBV) IgA/VCA antibody among 148,029 persons age 30 years and older who were tested during 1978-1980. Among the IgA/VCA antibody-positive persons, 55 nasopharyngeal carcinoma (NPC) cases were detected. Follow-up studies were carried out yearly on the IgA/VCA antibody-positive persons for 1-3 years, and 32 additional NPC patients were diagnosed. IgA/VCA antibody was detected 8-30 months (average, 13 months) prior to the clinical diagnosis of stage I NPC. There was no marked difference in geometric mean titers of IgA/VCA antibody between the period before onset of NPC and after diagnosis at stage I, but antibody titers were higher during stages II-IV. The NPC detection rates for all persons tested serologically and for IgA/VCA antibody-positive persons, respectively, was 2- and 82-fold the annual incidence of NPC in the general population of the same age group. These data further indicate that serological testing is valuable for the diagnosis of NPC, especially in its early stages, and that EBV may play an important role in the development of NPC.
