[Follow-up study on anti-HBs levels in vaccines after two and three doses of HB vaccine (1)].

UNLABELLED: An HB prophylaxis vaccination that included a primary and secondary vaccination was carried out on persons working at this university hospital. In the primary vaccination, the subjects were inoculated the second time with a vaccine derived from human blood plasma obtained from the Kitazato Therapeutic Research Institute. The third time, they were inoculated with a vaccine from the Chemo-Sero Therapeutic Research Institute derived from a second-generation vaccine organized ferment. The vaccine used for the second inoculation was obtained from the Chemo-Sero Therapeutic Research Institute. RESULTS: A total of 254 subjects were inoculated with the HB prophylaxis vaccination. 1. Of the 216 subjects inoculated with the primary vaccination, at the time of the second inoculation, 65 subjects (30%) tested positive for antibodies 3-4 months following inoculation. There was an especially high rate among females between 20 and 50 years. Thirty-two subjects (15%) tested positive 15-16 months following inoculation with a high rate among females. 2. Among 132 subjects inoculated the third time with the primary vaccination (those who tested negative in the second inoculation of the above vaccine), 76 subjects (58%) tested positive for antibodies 8-9 months following inoculation with a generally high rate among females. Thirty-five subjects (27%) tested positive 15-16 months after inoculation with a high rate among females between 20 and 30 years and among males between 40 and 60 years. 3. Among the 38 subjects who were inoculated the second time with the secondary vaccination, 8 subjects (21%) tested positive for antibodies 5 months following inoculation, with a high rate among females in their 20's.

[Follow-up study on anti-HBs levels in vaccinees after two and three doses of HB vaccine. (2)].

An HB prophylaxis vaccination that included a primary and secondary vaccination was carried out on persons working at the university hospital. In the primary vaccination group, the subjects were inoculated the second time with a vaccine derived from human blood plasma obtained from the Kitazato Therapeutic Research Institute. The third time, they were inoculated with a vaccine from the Chemo-Sero Therapeutic Research Institute derived from a second-generation vaccine organized ferment. The vaccine used for the second inoculation group was obtained from the Chemo-Sero Therapeutic Research Institute. Results were summarized as follows: 1) The primary vaccination group: (1) The number of the 153 subjects inoculated with the primary vaccination at the time of the second inoculation, 49 subjects (32%) tested positive for antibodies 3-4 months following inoculation. Thirty-two subjects (20%) tested positive 15-16 months following inoculation with a high rate among females. (2) Among 104 subjects inoculated the third time with the primary vaccination (those who tested negative the second inoculation of the above vaccine), 61 subjects (58.7%) tested positive for antibodies 8-9 months following inoculation with a generally high rate among females. Twenty-eight subjects (26%) tested 15-16 months after inoculation with a high rate among females between 20 and 30 years and among males between 40 and years. 2) The secondary group: Among the 38 subjects who were inoculated the second time with the secondary vaccination, 8 subjects (21%) tested positive for antibodies 5-6 months following inoculation, with a high rate among females in their 20's. 3) The rate of antibodies formation.(ABSTRACT TRUNCATED AT 250 WORDS)

[Basic investigation of saliva SIgA].

Saliva, which contributes to maintaining health in the oral environment, is affected by the physiological functions of the organism and their condition. Dental caries and periodontosis, both of which are oral diseases with frequent occurrence, require the presence of bacteria to occur. SIgA (secretory IgA), an immune globulin that is found in large quantities in substances secreted during salivation, has an antibacterial action. Thus, in conducting a basic investigation on the relationship between these factors, the author investigated what effect the speed of saliva secretion, a physiological factor of the saliva component, has on the SIgA value. Results showed that, regarding the relationship between the salivary SIgA value and the speed of salivary secretion, a negative correlation exists although this is weak in terms of relevance. The fact that the correlation displayed a tendency toward scattering indicates a need to pay attention when measuring the elements in the saliva to those factors that evidently have an effect on the composition of the saliva.

[Hepatitis B virus and epidemiological study on efficacy of HBIG and vaccine for the prevention of type B hepatitis after accidental exposures among medical staffs (2)].

The best method of preventing HBV is accurate perception on the part of the patient. There is a need for sufficient care regarding patient blood with HBsAg (+), HBeAg (+) and HBc high-antibody titer. The following is a report on a follow-up survey regarding antibody titer following dosages of HBIG 2 V and 1 V and administration of a vaccine along with dosage of HBIG 1 V. 1. Dosage of HBIG 2V: (Female) Antibody titer was recognized two days following dosage. It continued for two weeks and disappeared after four weeks. (2) (Male) Antibody titer was recognized one day following dosage but disappeared after two weeks. 2. Dosage of HBIG 1 V: (Female) Antibody titer (-) was recognized two days after dosage and nine days after dosage. It continued for about one month and disappeared after five months. 3. Administration of three vaccines and dosage of HBIG 1 V: (Female) Antibody titer was recognized two days after HBIG 1 V dosage and continued for 18 days but disappeared after three months. Antibody titer was recognized again after about eight months and showed signs of continuing for 13 months.

[Basic investigation of saliva and serum SIgA].

The local immune mechanisms of which the IgA system is central are characterized by activity that is independent of the immune response of the body as a whole. Among these mechanisms, SIgA (secretory IgA) plays an important role. In measuring saliva/serum SIgA, the author used an EIA SIgA column set for saliva and for serum. Investigation of saliva SIgA concerned the correlation with saliva flow speed while investigation of serum SIgA concerned patients with oral dysfunctions and those inoculated with the HB preventive vaccine. A slightly negative correlation was observed between the saliva flow speed and the saliva SIgA value. Regarding serum SIgA, effect from the liver function was considered to be a factor among patients with oral dysfunctions. The antibody positive subjects among those inoculated with the HB vaccine are considered to reflect the response level of the antibody factor as well as individual differences in sensitivity and immune response. Among antibody negative subjects, however, there was a general tendency toward high values.
