Seasonal level of hemoagglutinin inhibitinlt and its 2-mercaptoethanol sensitive antibody in the sera of swine (Epidemiological Study on Japanese Encephalitis, 67)

Seasonal level of hemoagglutinin inhibiting and its 2 -mercaptoethanol sensitive antibody in the sera of swine were researched and the following results were obtained. 1. The positive rate of hemoagglutination inhibit reaction (HI reaction) on swine showed 100% at maximum in the middle of September. 1980. The positive rate of 2-ME sensitive antibody showed the titer of over 1 : 40 with all swine examined in the middle of August, 1980. 2. The positive rate of HI reaction of inhabitants at Mukaiyama in Kurashiki City was 76.0% (on 8th in July, 1980) indicating the rather big decrease being compared with annual value of 90.6%, in 1976. Date indicated that increase In JE virus in swine as source of infection thought to be a vector of JE, caused a genuine case of JE, in 1980, as described below. 3. Higher positive rate of HI reaction and 2-ME sensitive positive rate of swine were observed in 1980. 4. One patient who suffered from JE was found In Kurashiki City in 1980. 5. Henceforth and continuously, Japanese Encephalitis should be investigated, above all on its occurance order with the number or Ct or the positive rate of hemoagglutination inhibit reaction in inhahitants and swine, etc. considering that J.E. has a high lethality rate and often leaves the terrible J. E. residue to patients

Pharmacokinetic drug interactions of antimicrobial drugs:a systematic review on oxazolidinones, rifamycines, macrolides, fluoroquinolones, and Beta-lactams

Like any other drug, antimicrobial drugs are prone to pharmacokinetic drug interactions. These drug interactions are a major concern in clinical practice as they may have an effect on efficacy and toxicity. This article provides an overview of all published pharmacokinetic studies on drug interactions of the commonly prescribed antimicrobial drugs oxazolidinones, rifamycines, macrolides, fluoroquinolones, and beta-lactams, focusing on systematic research. We describe drug-food and drug-drug interaction studies in humans, affecting antimicrobial drugs as well as concomitantly administered drugs. Since knowledge about mechanisms is of paramount importance for adequate management of drug interactions, the most plausible underlying mechanism of the drug interaction is provided when available. This overview can be used in daily practice to support the management of pharmacokinetic drug interactions of antimicrobial drugs

Variation in the incidence and causal factors of Japanese Encephalitis in Okayama Prefecture from 1950 to 1989

Variation in the incidence and causal factors of Japanese Encephalitis in Okayama Prefecture from 1950 to 1989 were surveyed, with results revealing, first, that incidence rates of Japanese Encephalitis peaked first in 1950 and then again in 1956 and 1964, with cases of Japanese Encephalitis rarely found since 1971. Second, positivity rates of hemoagglutination inhibition antibody tests decreased after July 1967. Third, the numbers of swine per pigsty has increased annually, indicating that large-scale pigsties have been constructed. Fourth, the prevalence of culex tritaeniorhynchus decreased beginning in 1965 though it has gradually recovered since 1974. Fifth, the vaccination rate of the inhibitants of the area increased beginning in 1957, peaked in 1967, and has since gradually declined. Finally, the relationship between changes in causal factors of Japanese Encephalitis and the declining incidence of the latter in Okayama Prefecture since 1966 are discussed
