Evaluation of influenza A/New Jersey/76 split-product virus vaccine in a summer camp.

An evaluation of two doses of split-product A/New Jersey/76 virus vaccines was conducted at a boys' summer camp. Two doses of either 200 chick cell-agglutinating (CCA) or 400 CCA units of vaccine were administered four weeks apart. There were no significant side effects. Of 60 subjects, 59 developed a significant titer of serum antibody after two doses. There was no correlation between titer of antibody and total dose of vaccine. Younger subjects developed a higher titer than older subjects. A single dose of vaccine was insufficient to achieve a protective level of antibody.

[Complications of resuscitative measures with special regard to liver damage (author's transl)].

Dissection material comprising 71 cases (total material evaluated: 3,082 post-mortem examinations) in which resuscitation measures are known to have been carried out in the case history showed 46.5% resuscitation damage, including an incidence of liver ruptures of 8.5% (6 cases), which are given special prominence. In the event of substantial haemascos and temporarily successful resuscitation rupture of the liver has been found to be a significant factor in the advent of death. Liver rupture cannot always be avoided during external cardiac massage even if performed professionally. The fact that the ruptured liver is attributable to resuscitation does not warrant the conclusion that external cardiac massage has been carried out incompetently.

[Post mortem temperature equilibration of the structures of the head. I. Thermometric techniques and principal investigations (author's transl)].

Special thin and flexible thermometric probes showing a diameter of 1 mm and a sharp end were used for post mortem (p.m.) thermometric studies in several tissues. Brain temperatures were measured by inserting a double probe through the superior orbital fissura thus allowing to record the central and the peripheral brain regions separately. Another probe was inserted into the galea and a fourth into the liver. Temperature changes were recorded simultaneously. Many variables of the human head were measured. Sixteen corpses were investigated. The results were as follows: 1. Of all temperature curves registered those of the central brain regions showed the smallest variance. 2. The p.m. temperature curve of the brain shows a sigmoid shape with a rather short "plateau" in the beginning. 3. In the early p.m. phase there is an increasing difference of temperatures between central and peripheral brain regions amounting to 2-4, 6 degrees C in the time period between 78th and 128th minute. 4. The insertion of the thin probes does not cause visible damages. Thus it should be considered for use in forensic practice. 5. Some artificial "head models" were constructed and temperature decrease recorded after warming. The curves showed the same type of sigmoid shape as those obtained from the corpses. 6. Of the possible variables measured that could influence the temperature decrease only the density of the hair seems to be of interest.

Production of rats in synchronised batches.

Successful synchronisation of copulations and births for the 1st parity permit continued synchrony of parturitions in subsequent parities. Foetal implantation after post-partum copulation was delayed by multiples of the oestrous cycle; both season and number of sucking neonates influenced the time of implantation. Post-weaning matings gave a high conception rate with a parturition spread of 36 hours for 94% of the original group.

Error rates in cervical cytological screening tests.

In an attempt to clear up the confusion evident in the literature concerning some aspects of cervical cytological screening tests, the principle is stated upon which the data acquired in a series of tests should be tabulated. The table is used to define several rates or probabilities, most of which express the rates at which errors occur. Certain rates are distinguished as of basic importance, others playing only a secondary role. The inter-relations of the rates are displayed as equations and reference is made to a set of conversion tables constructed from the equations. As an illustration, the data from a particular published paper is treated in detail, showing how the various rates can be calculated or estimated, and, in passing, also demonstrating their high degree of uncertainty.
