sero-epidemiology of the epstein-barr virus: preliminary analysis of an international study - a review.samples of chinese, indian, african and caucasian populations, randomly selected in hong kong, singapore, the west nile district of uganda, and nancy, france, were titrated for antibodies to ebv, viral capsid (vca) and complement-fixing soluble (cf/s) antigens. the age-specific prevalence of infection (as reflected by the proportion of vca-positive individuals) varied greatly up to the age of 10 years in the four populations studied, the west nile district of uganda being outstanding in having a ...1975191375
absence of detectable hepatitis b antigen (hbag) in the commercial oyster, crassostrea gigas thunberg, in hong kong.the locally grown commercial oyster in hong kong, crassostrea gigas thunberg, is faecally polluted particularly in the summer months at a time when oyster consumption and the incidence of viral hepatitis similarly increase. whole oysters and isolates of tissues including the digestive diverticula and mantle fluids, in unconcentrated or concentrated forms were examined by counterimmunoelectrophoresis for the presence of the hepatitis-b antigen (hbag); no antigen was detected in samples examined o ...19751221500
epidemiology of influenza in the elderly: evidence of virus recycling.during the hong kong influenza epidemic of 1968-1969 the attack rate among persons born prior to 1890 was about one-third the rate among persons born after 1899. during an asian influenza epidemic in the same community two years earlier there was no apparent age effect. most persons born before 1890 had detectable pre-epidemic antibody against a/hong kong/68 whereas most persons born after 1899 had no detectable pre-epidemic antibody. the lower attack rate in the older age group is consistent wi ...19761251831
clostridia isolated from faeces.clostridia were isolated from human faecal samples from england, scotland, wales, usa, hong kong, uganda and japan. strains were identified on the basis of various biochemical reactions and on the type of fatty acid produced from glucose. analysis of these acids was by gas-liquid chromatography. clostridium paraputrificum was common in stool samples from england, scotland, wales, and usa, but rare in samples from hong kong, uganda and japan.19761263249
light microscopic morphology of viral hepatitis.the histopathology of acute and chronic infections associated with viral hepatitis is reviewed and illustrated. particular attention is directed to changes that help to differentiate chronic persistent from chronic active viral hepatitis. features that help to identify the intravenous drug abuser who has hepatitis, whether acute or chronic, include the presence of particulate birefringent material (usually talc) in reticuloendothelial cells, as well as tissue eosinophilia. ground-glass hepatocyt ...1976802746
an influenza simulation model for immunization studies.a stochastic simulation epidemic model based on discrete time intervals and appropriate for any infectious agent spread by person-to-person contacts is presented. the population is highly structured, allowing for five age groups and for subgrouping mixing in families, neighborhoods, schools, and preschool playgroups as well as total community mixing. with proper choice of relative susceptibility by age, length of latency and infectivity periods, pathogenicity and withdrawal patterns, and the rel ...1976814808
some observations on the needs of ergonomics in industries in hong kong.the author's interest in ergonomics lies in the common ground it shares with occupational health, since ergonomics aims to make work easier, safer, and more productive and to promote efficiency, comfort, and health. in hong kong, owing to lack of natural resources and guaranteed markets, industrialization has not taken a smooth course. only light industries exist, and one industry flourishes after another. occupational health and safety tends to be neglected not only by the employers but by the ...19761030445
mucin histochemistry of human cholangiocarcinoma.histochemical studies of mucins were carried out on 17 autopsy specimens of cholangiocarcinomas associated with clonorchiasis. all tumours produced epithelial mucins which were mixtures of neutral and acid mucopolysaccharides without any histochemically demonstrable components of sialic and uronic acids. the mucins were qualitatively similar to that secreted by normal and clonorchis-infested bile ducts. however carboxymucins were reduced and sulphomucins were absent or present only in trace amou ...1976131185
results of virological and serological studies of three influenza a hong-kong epidemics in leningrad.an analysis of morbidity of the population in the course of 3 influenza a/hong-kong epidemics showed a pronounced decrease in influenza affection of adult population in the last epidemic in 1971--1972. comparative studies of the diagnostic value of cfr and hit demonstrated identical sensitivity of cfr as a method of influenza diagnostics in both the epidemic and interepidemic periods. hit was suitable for the detection of influenza only in the epidemic period. in the interepidemic period, the pe ...1976135027
influenza a neuraminidase antibodies in children and young adults studied by serum absorption.a study is described of influenza a anti-neuraminidase antibodies in the sera of young people of three different groups. each serum was individually absorbed with viruses containing the n2 neuraminidases of 1957, 1968 and 1972. rabbit antisera prepared against the viruses were similarly absorbed. results obtained with the animal sera suggested that these neuraminidases were antigenically distinct, but the human sera had a broader range of anti-neuraminidase activity and gave indication of asymme ...1977265343
salmonella in pig carcasses for human consumption in hong kong: a study on the mode of contamination.a very high proportion (75%) of the pigs slaughtered in hong kong were found to be infected with salmonellas. seven serotypes including salmonella choleraesuis were isolated but the majority (91%) were s. anatum and s. derby. these serotypes, especially s. anatum and s. derby, had been isolated frequently from clinical cases, symptomless carries and in this study from abattoir workers, suggesting that the pig was a significant source for human salmonella infection. the majority of pigs slaughter ...1977265345
cold lymphocytotoxic antibodies in nasopharyngeal carcinoma.sera from patients with nasopharyngeal carcinoma (npc), a disease associated with epstein-barr virus (ebv), were found to be cytotoxic at 15% degrees c in the presence of complement for a panel of human lymphocytes, with a higher frequency than those of matched controls. the cold lymphocytotoxic antibodies (lta) responsible for this activity have the same properties as those described in sera from individuals with acute viral infections. the frequency and geometric mean titres (gmt) of lta varie ...1977192260
neutralizing ebv-specific iga in throat washings of nasopharyngeal carcinoma (npc) patients.throat washings from 26 nasopharyngeal carcinoma (npc) patients from hong kong and tunisia were studied for the presence of transforming ebv. only six (23%) were found positive which led to the hypothesis of a neutralizing factor in such salivas. the search for ebv-specific antibodies showed that npc saliva contained neutralizing vca and ea iga (54 and 27% respectively) and vca and ea igg (73 and 54% respectively). both transforming and non-transforming throat washings contained virus particles ...1977193801
acute haemorrhagic conjunctivitis in hong kong 1971-1975.acute haemorrhagic conjunctivitis occurred in epidemic in hong kong in 1971 and 1975 respectively. two picornaviruses, the enterovirus type 70 and an antigenic variant of coxsackie virus type a24, were isolated during the 1971 outbreak, while only the latter virus was detected in the 1975 outbreak. in 1972 and 1974, sporadic cases of conjunctivitis associated with enterovirus type 70 were observed. serological survey in late 1975 showed a high proportion of the population might still be suscepti ...1977196351
comparative studies on immunity to ebv-associated antigens in npc patients in north america, tunisia, france and hong kong.this study compared the relative antibody titers to ebv-related antigens in patients with nasopharyngeal carcinoma (npc) and controls from a high-incidence (hong kong), an intermediate incidence (tunisia), and two low-incidence (france, north america) areas to determine which of several ebv antibodies best differentiated npc patients from controls. antibodies measured include anti-virus capsid antigen (vca), anti-early antigen (ea), anti-soluble antigen by complement-fixation (cf) and antibody-d ...1977198381
histocompatibility leukocyte antigen patterns and nasopharyngeal carcinoma.incidence patterns indicated the prominent role of genetic factors in this type of cancer. a histocompatibility leukocyte antigen (hla) profile of a2 and b-locus antigen, singapore 2 (sin 2), was identified. an association between these genes and increased risk for nasopharyngeal carcinoma (npc), was confirmed. the risk was restricted to the "co-occurrence" of a2, b-sin 2, suggesting that the genotype predisposing to the development of npc was the a, b-sin 2 haplotype. similar associations were ...1977613232
identification of a swine influenza virus (hsw1n1) isolated from a duck in hong kong.an influenza a virus isolated from a duck during a recent surveillance study on commercial poultry from the people's republic of china and the new territories, hong kong, was shown to possess hswl antigens related to that of the swine (hsw1n1) influenza virus. the isolation of an hsw1n1 influenza virus from ducks indicates that avian species, as well as pigs, may serve as a reservoir of this potential pathogen for humans. the virus was avirulent for ducks, turkeys, chickens, and pigs.1978712123
descriptive and analytical epidemiology of nasopharyngeal cancer.information concerning the descriptive and analytical epidemiology of npc that has been reported mainly since the first international symposium on the subject in singapore in 1964 are reviewed. npc is rare in most countries in the world, with an age-adjusted incidence rate of less than 1 per 100,000, and the incidence rate is twice as high in males as in females. chinese of southern origin have a uniquely high risk, the incidence rates per 100,000 being 10--20 in males and 5--10 in females. the ...1978215514
differences in ebv antibody titres of patients with nasopharyngeal carcinoma originating from high, intermediate and low incidence areas.in order to assess the differences in serological reactivities of npc patients from high, intermediate and low incidence areas, 288 npc sera from hong kong, singapore, tunis, east africa, paris and los angeles, together with sera from patients with ear, nose and throat tumours other than npc and with those from normal individuals from the same areas, were tested 'blind' with the same batches of antigen. important differences (up to 3-fold) in the gmts of antibodies directed against vca, ea and e ...1978215529
autoantibodies (cold lymphocytotoxins, antiactin antibodies and antinuclear factors) in nasopharyngeal carcinoma patients.lta, sma and ana were found at higher frequencies in sera from npc patients than in those from matched controls. the frequency and gmts of lta-positive sera varied with the origin of the patient (chinese greater than north african greater than caucasian, thus paralleling the risk for npc in each ethnic group) and the stage of the disease (stage iv greater than stage i). a positive correlation was found between lta and anti-ebv titres with regard to anti-vca and anti-ebna antibodies. sma were spe ...1978215532

hong kong: population: legalized abortion.abortion was legalized in hong kong on february 17 when the legislative council, by a vote of 40 to 7, approved the controversial abortion bill. passage of the measure immediately drew a reaction from catholic bishop john baptist wu who denounced it as against the principles of human rights. he said that unborn children, regardless of whether or not they had a suspected handicap, have the right to live. he said that: "if we ignore or deny this right, we discriminate against the weak and the h ...198112262369
avian influenza a viruses of southern china and hong kong: ecological aspects and implications for man.continuous surveillance of the influenza viruses isolated from domestic poultry from southern china and hong kong over more than 4 years resulted in the isolation of influenza viruses possessing 46 different combinations of haemagglutinin (h) and neuraminidase (n) subtypes. of these, 43 were obtained from ducks from china. in all cases, infection appeared to be asymptomatic. the antigenic combination found most commonly in the viruses isolated was h4n6, which accounted for approximately one-quar ...19826979416
nasopharyngeal carcinoma in american children: epstein-barr virus-specific antibody titers and prognosis.seven american juvenile patients with undifferentiated or nonkeratinizing nasopharyngeal carcinoma (npc) were examined serially for epstein-barr virus (ebv)-specific antibody spectra and titers in sera. at diagnosis, all showed antibody patterns characteristic of npc: i.e., high titers of igg antibodies to viral capsid antigen (vca) and to the diffuse (d) component of the early antigen complex. six patients had iga antibodies to vca, and four to the d component. in the patients who responded to ...19826174465

antibodies to fastidious faecal adenoviruses (species 40 and 41) in sera from children.three hundred and seventy-seven single sera from children in the united kingdom, hong kong, new zealand, gambia, guatemala, and kuwait were tested for antibodies to fastidious fecal adenoviruses (species 40 and 41) by neutralisation test using a variant of ad41 (ad41a). all children were less than 12 years of age, and at least 41.1% of the total tested had antibodies. one hundred and fifty-four of these sera were collected during the 1960s from london children attending day nurseries, and 54.5% ...19836308143
forfeiture of proceeds of drug-related crimes: a british commonwealth perspective.the forfeiture of the proceeds of drug-related offences does not seem to have received much attention as yet from british commonwealth countries. whereas in some of these countries specific legislation exists in relation to forfeiture, in many other countries the act of forfeiture falls within the purview of general criminal law. forfeiture presupposes enquiry and search, two procedures which involve integral aspects of present-day human rights law, and which seem to be impeded at almost every s ...19836556074
