Abstract:
If the occurrence of certain agents and their possible doses is human body could be shown by environmental monitoring, then their actual loads in human body could be estimated by human biological monitoring (blood, urine, hair, tissue and organ, etc). Hence the exposure levels of human body to these agents could be evaluated, especially certain materials such as trace elements and organic chlorine compouads. Based on the monitoring of pulmonary trace elements composition, it was preliminarily considered that the results of adult pulmonary monitoring could practically reflect the features of atmospheric inorganic elements is inabited areas.

Abstract:
Four strains of monoclonal antibody (McAb) secreting hybridoma cell were established through fusion of mouse myeloma cell and BALB/C mouse splenic cell immunized with Ogawa strain (18001)of Vibrio cholerae (biotype El Tor).These cells, no matter when they were cultured in vitro or in vivo, were shown to be able to produce McAb against Ogawa, Inaba and Hikojima strains of V.cholerae,with high specificity. The immunoglobulin of one cell line belonged to IgG2b subclass, while those of the other three cell lines, nll Ieloaged to IgM.

Abstract:
Five strains of Aeromonas hydrophila(A.h.) and one strain of Plesiomonas shigelloides(P.s.)were isolated from patieats with acute diarrhea from August to October 1983 in the city of Wuhan, Hubei Province. Biochemical reactions and other characteristics of the isolates were consistent with those of the typical species.The isolatioa rates for A.h. and P.s. were 6.3% and 1.3% respectively.Relative importance of A.h. among the enteropathogenic bacteria was only next to ETEC and Shigellae.

Abstract:
The distribution of serum antibody to Legionella pneumophilla type B1 in the general population of the city of Harbin, Heilongjiang Province was observed.The results showed that the antiboty positivity rate was 4.98% in population of that city and the GMT was 1:1.63. Both the antibody positivity rate and the GMT were not significantly different between two sexes,but both of them increased with the increase in age. Among different professionals, the antibody positivity rate and the GMT were highest in transport, hotal and theater workers and were lowest in office workers.

Abstract:
Observations on the incubation period of artificial infection of Plasmodium vivax is the temperate zone in the northwestern part of Yunnan Province aad the tropics-subtropics of southern part of the were carried out in 1982-1984.It was demonstrated for the first time that the length of the same province incu- bation period of tertian malaria in both the tropics to the south of Tropic of Cancer and the temperate zone at 27º13' N.latitude was similar.The plasmodia causing different incubation periods belong to the same strain.

Abstract:
Deltamethrine is a new insecticide. This paper deals with the toxicity of this drug to larvae, pupae and adults of Culex tritaeniorhynchus and C.pipien.The LC50 of deltnmethrine for the larvae of C.tritaeniorhynchus is 8.4 × 10-7 ppm and for the pupae 5.02 × 10-7 ppm, and that for the larvae and pupae of C.pipien is 9.55 × 10-6 ppm and 5,02 × 10-6 ppm respectively.

Abstract:
In order to study the relationship between zinc and copper and common diseases of the middle and old aged persons, the levels of serum zinc and copper and their ratio in 2339 workers and inhabitants of 50 years and older years of age in an inhabited area and a high school of Haidian district in Beijing were measured is 1984. The persons examined were divided into the following groups: 1) diseased (hypertension, borderline hypertension, coronary heart disease,anemia,diseases of bones and Ioints) comprised 1359 indivi- deals below 60 years of age and 447 persons of 60 years and older, 2) healthy com prised 457 persons belo w 60 years of age and 76 persons of 60 years and older.The results of measurtment indicated that the values of zinc and copper of the healthy group were within the normal range as those usually reported.
