Reassessment of data used in setting exposure limits for hot particles

Description: A critical review and a reassessment of data reviewed in NCRP Report 106 on effects of hot particles'' on the skin of pigs, monkeys, and humans were made. Our analysis of the data of Forbes and Mikhail on effects from activated UC{sub 2} particles, ranging in diameter from 144 {mu}m to 328 {mu}m, led to the formulation of a new model for prediction of both the threshold for acute ulceration and for ulcer diameter. A dose of 27 Gy at a depth of 1.33 mm in tissue in this model will result in an a… more

Acute skin lesions due to localized ``hot particle`` radiation exposures

Description: Purpose of the studies was to determine incidence and severity of lesions resulting from localized deposition of dose to the skin from small (<0.5 mm) discrete radioactive particles. Hanford mini-swine were exposed to localized doses from 0.2 to over 600 Gy (averaged over 1 cm{sup 2} at 70{mu}m depth) from isotopes having max beta particle energies from about 0.3-3 MeV. Incidence of erythema and scabs (indicating ulceration) were scored routinely for up to 71 days post-irradiation. Responses fo… more

Hog Prices: Questions and Answers

Description: This report discusses price changes in the pork industry. In late 1998, the lowest hog prices in decades created a crisis in the pork industry and prompted the U.S. Department of Agriculture (USDA) and Congress to take a series of actions to assist producers, including direct cash payments, and the purchase of extra pork products to reduce market supplies. The industry sought additional aid as low prices persisted into 1999.

The Relationship Between the Surface Appearance and Depth of Damage of Subfabric and Bare Skin Burns Produced by Radiant Thermal Energy

Description: In a series of 600 cutaneous burns in swine produced by radiant thermal energy at 0.5 and 5.0 sec exposure time, the relationship of thc surface appearance and the depth of damage of bare skin and subfabric burns was investigated. The fabrics used were a black and a gray sateen weighing 8 to 9 oz/ yd/sup 2/. It was found that there is no significant difference in the 1+ burns whether produced on bare skin or beneath fabric, either at 0.5 or 5.0 sec exposure. However, the 2+ subfabric burns aver… more

Studies on Large Area Sub-Fabric Burns: The Effect of an Air Space Between a Two Layer System

Description: It is well known that protection against radiant energy burns afforded by fabrics may be increased by creating an air space between the fabric and the underlying skin. Earlier work in this laboratory has also shown that if one layer of fabric is in contact with skin, protection of a two layer fabric system increases progressively as the space between the fabrics changes from two to five millimeters. With the magnesium source, large area sub-fabric burns were produced to determine the cffects of… more

Estimates of dose to systematic organs and GI tract based on data from miniature swine orally intubated with a single dose of Am-241 citrate

Description: A model is presented for the internal radiation dose to the small intestine wall of miniature swine given Americium 241 citrate by oral intubation. The model incorporates the uptake of the Am-241 by the intestinal wall. About equal contributions of dose to the small intestine were observed from the intestinal contents and the wall itself. (ACR)

Natural iodine and iodine-129 in mammalian thyroids and environmental samples taken from locations in the United States

Description: From symposium on enviromnental surveillance around nuclear installation; Warsaw, Poland (5 Nov 1973). Bovine and other mammalian thyroids, air, precipitation, water, grass, and milk samples from selected locations were analyzed for their natural iodine and iodine-129 content. Particle filters and activated charcoal beds were used to collect the particulate and gaseous iodine fractions from the air. Anion exchange was used for the separation of iodine from liquid samples. Cumbustion methods wer… more

Whole-genome analyses of the speciation events in the pathogenic Brucellae

Description: Despite their high DNA identity and a proposal to group classical Brucella species as biovars of B. melitensis, the commonly recognized Brucella species can be distinguished by distinct biochemical and fatty acid characters as well as by a marked host range (e.g. B. suis for swine, B. melitensis for sheep and goats, B. abortus for cattle). Here we present the genome of B. abortus 2308, the virulent prototype biovar 1 strain, and its comparison to the two other human pathogenic Brucellae species… more

Serological testing for trichinosis in pigs

Description: A test system suitable for rapid and economical screening of large numbers of swine for antibodies to Trichinella spiralis is being developed. It was demonstrated that the soluble antigen-fluorescent antibody (SAFA) test can detect T. spiralis antibodies earlier and in swine fed fewer larvae than other tests. An enzyme-labeled antibody test (ELA) is being developed which is similar in principle to SAFA, but was shown to be more sensitive than SAFA by comparison in a double blind test on sera fr… more

Prospects for use of the ELA test in control of trichinellosis in swine

Description: A practicable system for examining food animals at the time of slaughter to detect the presence of humoral antibodies against diseases of significance to human or animal health would be a valuable adjunct to meat inspection. Trichinosis, which has the characteristics of many of the disease problems that are of interest to the Meat and Poultry Inspection Program, was selected as a model for this purpose. Preliminary work indicated that the enzyme-labeled antibody test (ELA) could be used for det… more

Serum fractions associated with positive and false positive reactions in the ELA test for trichinellosis in swine. [Accuracy of packinghouse tests for Trichinella in pork]

Description: A considerable number of packinghouse swine sera give false positive results in the enzyme-labeled antibody (ELA) test for Trichinosis. Efforts to understand the nature of this problem directed toward isolation and identification of a serum factor responsible for the false positive reactions are discussed.

Cell kinetics of differentiation of Na/sup +/-dependent hexose transport in a cultured renal epithelial cell line

Description: Fully differentiated cells of the renal proximal tubule have the capability of taking up hexoses across their apical borders by transport coupled to the Na/sup +/-electrochemical gradient. This property is also found in postconfluent cultures of the cloned cell line LLC-PK/sub 1/, a morphologically polarized line of renal cells. Postconfluent cells develop the Na/sup +/-dependent capacity to transport hexoses at their apical surface. This function is not observable during the growth phase of th… more
