ABSTRACT
Pork, beef and chicken meat samples were collected from slaughter houses, poultry-processing plants and meat shops. Rates of incidence of Salmonella spp., Campylobacter jejuni and C. coli with respect to the sample size were compared and the most probable number for these species were determined. Salmonella spp. were detected in 69 (24.1%) of 286 chicken meat samples, in three (3.2%) of 94 pork samples, and in one (1.9%) of 52 beef samples. With chicken meat, the rates of detection were: 19.9% in 25-g, 15.7% in 10-g, and 12.2% in 1-g samples. The populations in most probable numbers, that gave positive results in 31 (20.8%) of 149 samples, ranged from 30 to 10(4) per 100 g, the majority (93.5%) being between 30 and 10(3) per 100 g. C. jejuni and C. coli were detected in 106 (67.9%) of 156 chicken meat samples, in two (2.1%) of 94 pork samples, and none of 52 beef samples. The results obtained with different sample sizes of chicken were compared. Positive rates were 55.8%, 39.7%, 27.6% in 10 g, 1 g, and 0.1 g, respectively. The most probable numbers in 107 (68.6%) positives out of 156 chicken samples examined ranged from 30 to 10(6) per 100 g: 46 (29.5%) contained between 10(2) and 10(3) per 100 g, 22 (14.1%) between 10(3) and 10(4) per 100 g, and the other 19 samples (12.2%) between 10(4) and 10(5) per 100 g.

Renography and renal imaging with 123I-orthoiodohippurate (OIH) were performed in 29 patients with various renal diseases, and a comparison made with 131I-OIH. In all patients, renograms and images with 123I-OIH were superior to those with 131I-OIH, because of the increased density and image excellence of 123I-OIH. In addition, dynamic images to evaluate renal blood flow, as well as high quality sequential excretion images, can be obtained with 123I-OIH. From our clinical results, 123I-OIH is expected to replace 131I-OIH in renal function studies.

Two cases of primary pulmonary non-Hodgkin lymphoma were presented. Case one had diffuse, homogeneous consolidation with air bronchogram in rt. upper lobe. Case two had a mass-like shadow with air bronchogram in rt. middle lobe. Both had no significant symptom, pleural effusion and lymphadenopathy. Patients with this entity had good prognosis.
