Histidine Decarboxylase Activity

The distribution of mast cells in muscle and liver of dystrophic mice was studied; histamine and histidine decarboxylase activity was also measured in the same tissues. Mast cells were significantly more numerous in dystrophic muscles. On the other hand, very few cells could be counted in the liver of either control or dystrophic animals. Histamine concentration was higher in muscle and liver of dystrophic mice; no visible increase in histidine decarboxylase activity could be measured by the methods used. It is concluded that histamine-binding capacity is increased in some tissues of dystrophic mice.

Histidine Decarboxylase Activity

The histidine decarboxylase activity of Enterobacter cloacae S15/19 was studied during the production process of salchichón, a Spanish ripened sausage. Counts of fecal coliform and histidine decarboxylase bacteria decreased during the production process, showing a good correlation in both inoculated and control samples. In the samples inoculated with Enterobacter cloacae S15/19, fecal coliforms were undetectable the last day of the survey, while the population of histidine decarboxylase bacteria was over 2 log MPN/g. Despite the fact that inoculation with Enterobacter cloacae S15/19 increased histidine decarboxylase bacteria counts, no differences were observed in the histamine concentration reached, which was undetectable in most of the control and inoculated samples. In contrast, cadaverine concentration increased significantly (P < 0.01) in the inoculated samples, suggesting that cadaverine could be used as a hygienic-quality indicator of the raw materials employed in sausage processing.

Histidine Decarboxylase Activity

The histamine content and the histidine decarboxylase activity of bone marrow have been studied in guinea pigs treated with foreign protein. In some experiments the effect of 6-methylprednisolone also was observed. Treatment of guinea pigs with foreign protein resulted in a 10-fold increase of both histamine concentration and histidine decarboxylating activity in the blood and bone marrow. Histamine levels and histidine decarboxylating activity were related to the number of basophils. A fairly constant relationship was found between the histamine content and the enzyme activity per basophil. The findings suggest that histamine is formed and to a certain extent also stored in the basophilic leukocytes.
