TL;DR: In March, 1975, and January, 1978, there were outbreaks of Korean haemorrhagic fever among staff in the animal laboratory of the clinical research building of Tohoku University hospital, and Epidemiological studies suggest that laboratory rats were the source of the infection.

TL;DR: A total of 53 patients infected with Taenia solium were treated with praziquantel in two different dose levels and all cases except one were completely cured, revealing a cure rate of 100 per cent.
Abstract: A total of 53 patients infected with Taenia solium were treated with praziquantel in two different dose levels. Twenty-six cases were treated with praziquantel in a single oral dose of 5 mg/kg body weight. All cases except one were completely cured. The cure rate was 96.2 per cent. The other 27 cases were treated with a single dose of 10 mg/kg body weight. All cases were completely cured and revealed a cure rate of 100 per cent. Side effects were mild and transient. About half of the cases complained of a mild abdominal pain. Soft stool or diarrhea and dizziness were observed in some cases. Tests on clinical hematology, serum biochemistry and urinalysis were performed immediately before and one day after treatment in all cases. There were no significant abnormalities detected in these tests.

TL;DR: In this article, high resistivity N-type silicons produced from high purity P-type silicon by neutron transmutation doping are used for fabrication of surface barrier detectors, and it has been shown that the materials tested have properties as good as those produced by the conventional floating-zone (FZ) method.
Abstract: High resistivity N-type silicons produced from high purity P-type silicon by neutron transmutation doping are used for fabrication of surface barrier detectors. It has been shown that the materials tested have properties as good as those produced by the conventional floating-zone (FZ) method. The resistivity distribution in a silicon rod produced by this method is expected to be better compared with those obtained by the FZ method, and the resistivity itself is also easily controlled by an irradiation dose of neutrons. The radiation damage produced by neutron bombardments seems to be removed by an annealing treatment. The residual radio-activity induced by irradiation of neutrons has almost negligible effects on the performance of the detector except for low background applications.

TL;DR: Thirteen guinea pigs and 23 rabbits were challenged with 300 metacercariae of Clonorchis sinensis each and the recovery of adult worms and egg counts in feces were compared at 11~13 weeks post-infection in guinea pig and rabbits and at 7~9 weeksPost- Infection in rabbits.
Abstract: Thirteen guinea pigs and 23 rabbits were challenged with 300 metacercariae of Clonorchis sinensis each and the recovery of adult worms and egg counts in feces were compared at 11~13 weeks post-infection in guinea pigs and at 7~9 weeks post-infection in rabbits. The recovery rate of adult worm was 23.5 percent in guinea pigs and 20.l~30.5% in rabbits. The mean E.P.G. of these animals in above period of infection was 106 in guinea pigs and 121 in rabbits. When one hundredth of E.P.G. was expressed as X and the number of adult worms as Y, the relationships between X and Y were as follows; Y=0.8X+10.8 in guinea pigs and Y=0.7X+6 in rabbits.

TL;DR: In this article, the healing length and other properties of helium films were analyzed in terms of a soft-potential model, and the roton gap and sound velocity may depend on the film thickness below 2.89 atomic layers.
