Thyroidal iodine metabolism was studied in four inbred strains of mice and two groups of F1 hybrids by use of radioiodine. Significant strain differences were found in both the 48-hour thyroidal retention of I131 and its output rate constant. Three closely related groups studied were C57BL/6, C57BR/cd and BBF1, their F1 hybrid. The other three groups included A/Jax, BALB/c and CAF1, their F1 hybrid. C57BL/6 mice had a significantly faster output rate and lower 48-hour I131 retention than any other group. The first three groups listed had a more rapid output rate and lower 48-hour retention than the last three. In intergroup comparisons and inverse relationship between I131 output rate and 48-hour retention was clearly shown. The results indicate that in mice pituitary TSH output, as indicated by thyroidal I131 output rate and thyroidal iodine pool size, is controlled by separate genetic factors.

The immune responsiveness of (NZB x NZW) F1 hybrid mice (NZB/W) has been compared with that of three other strains of mice, A/J, BALB/c, and CBA/J. The antigens used included sheep red blood cells (SRBC), keyhole limpet hemocyanin (KLH), bovine serum albumin (BSA), and human γ-globulin (HGG). It was found that important strain differences existed in the amount of antibody produced, but the relative immune responsiveness depended very much upon the nature of antigen. By comparison with the other strains tested, NZB/W mice had a higher antibody production to some antigens (SRBC and BSA) but were low responders to others (KLH). Induction of unresponsiveness to HGG by treatment with ultracentrifuged HGG was studied in the strains cited above. NZB/W mice became tolerant after injection of HGG ultracentrifuged at 100,000 g for 2 hr. Similar experiments carried out with another preparation of HGG (centrifuged at 20,000 g for 30 min) failed to reveal any abnormal behavior of NZB/W mice as compared to BALB/c or A/J mice. These results do not support the concept that NZB/W mice possess a general immune hyperreactivity or a relative inability to be made tolerant to protein antigens. However, they do not rule out the possibility that these mice have a genetically determined hyperresponsiveness to some antigens, in particular to nuclear antigens.

Visual Monitoring System

Recently, in the loading tests for steel members, the deformation value is measured by calculating a distance of both cross-heads. This measuring method encounters a test error due to various environmental factors, such as initial slip, etc.. Especially, in the case of welded members, the non-uniform deformation behavior in welded joints is observed because of the effect of welding residual stress and weld metal. This is mainly responsible for a test error and a loss of the reliability for used test instruments. Therefore, to improve the accuracy and the applicability of measuring system, it is necessary to employ a visual monitoring system which can accurately measure the local and overall deformation of welded members. In this paper, to accurately measure a deformation of welded members, a visual monitoring system (VMS) was developed by using three-dimensional digital photogrammetry. The VMS was applied to the loading tests of a welded member. The accuracy and the applicability of VMS was verified by comparing to the deformation value measured by a test instrument (MTS-810). The characteristics of the behavior near a welded joint were investigated by using VMS.

Designing the three dimensional (3D) GIS software used in monitoring mineral pipeline transporting system. The software can truly show and restore the geography of project and the features of terrain .The operator can not only examine and grasp the true situation of the distribution of pipeline, but also keep watch on the secure running of the pipeline by real-time remote video in the remote control room. The practical application indicates that the pipeline can run safely, stably and efficiently with the monitoring system.
