Histiocytosis X. S-100 protein, peanut agglutinin, and transmission electron microscopy study.
Twenty-seven cases of histiocytosis X (HX) for which paraffin blocks were available were studied with the use of S-100 protein immunohistochemistry, peanut agglutinin affinity histochemistry, and transmission electron microscopy. The results show that these techniques did enable identification of Langerhans'-type histiocytes in 88.5%, 75%, and 47.4% of cases, respectively. All techniques were proved to be of some diagnostic value for HX, but none was able to confirm the diagnosis in all instances and none could foretell the prognosis of the patients. This study shows that besides the Langerhans' cells, the indeterminate cells of the skin and the interdigitating dendritic reticulum cells of the lymph node may also be involved in this process. Moreover, some multinucleate giant cells and foamy cells may be derived from Langerhans' and related cells.

Induction of alpha-calcitonin gene-related peptide mRNA expression in rat dorsal root ganglia by heat stress involves the heme oxygenase-1/carbon monoxide pathway.
SD rats were pretreated with whole body hyperthermia (rectal 42 degrees C) for 15 min. The level of calcitonin gene-related peptide (CGRP) in plasma, and alpha- and beta-CGRP mRNA as well as heme oxygenease-1 and heme oxygenase-2 mRNA in dorsal root ganglia were determined by radioimmunoassay and semi-quantitative reverse-transcription polymerase chain reaction, respectively. Heat stress induced only the expression of alpha-CGRP or heme oxygenease-1 but not beta-CGRP or heme oxygenase-2 mRNA, and the release of CGRP and induction of alpha-CGRP mRNA expression were abolished by pretreatment with Zinc protoporphyrin IX, the heme oxygenase inhibitor, or methylene blue, the inhibitor of soluble guanylate cyclase. These results indicate that induction of alpha-CGRP mRNA expression in rat DRG by heat stress involves the heme oxygenase-1/carbon monoxide pathway.
