Tc-99m labeled leukocytes: preparation and use in identification of abscess and tissue rejection.

A simple and reproducible method for the preparation and labeling of leukocytes with Tc-99m has been developed. Leukocytes were separated from blood, incubated with stannous pyrophosphate, and then with 20-30 mCi (740-1110 MBq) of 99mTcO-4. In leukocytes separated from human blood, the labeling efficiency was 81% +/- 6% (n = 4). Experiments on dogs with abscesses showed accumulation of the Tc-99m-labeled leukocytes in the infected sites, indicating the viability of the labeled leukocytes. Additional studies showed that rat lymphocytes that were labeled with Tc-99m, using the same technique, localized in heart transplant tissue that was being rejected.

Psoriasis associated with human immunodeficiency virus in an infant.

Psoriasis is commonly reported in association with HIV in adults. A 3-month-old girl with HIV presented with a widespread eruption and was diagnosed with psoriasis. This is the first infant reported with psoriasis in association with HIV infection. The relationship between the two entities is discussed, as is the role of treatment with zidovudine.

Urine cannabinoid analysis: an integrated multi-method approach.

The Enzyme Multiplied Immunoassay Technique (EMIT) Urine Cannabinoid Assay (Syva) was adapted for automated analysis on a centrifugal analyzer allowing for cost-effective, rapid, high-volume urine testing. Confirmation of positive EMIT results was accomplished by a modification of a recently published high performance liquid chromatographic (HPLC) technique for 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH). Further confirmation of the presence of THC-COOH was achieved by high efficiency thin layer chromatography (HETLC). The reported protocol was applied to urine samples obtained from an emergency toxicology population and a drug counseling population. Results indicated that specimens testing positive by all three methods suggest valid forensic evidence for the presence of THC-COOH.
