Intravenous amphetamine abuse, primary cerebral mucormycosis, and acquired immunodeficiency

Two intravenous amphetamine abusers had fatal, rapidly progressive cerebral mucormycosis with abscess formation in the presence of absolute lymphopenia. Postmortem examination confirmed the primary nature of the fungal cerebritis, documented by postmortem culture and histology. The clinical and pathologic features of these cases are compared to previously reported occurrences of primary fungal cerebritis (and abscess) among intravenous drug abusers, including cocaine users. Primary fungal cerebritis associated with intravenous abuse of stimulant drugs is discussed as a possible variant of the acquired immunodeficiency syndrome.     

Behaviour of p-nitrophenol-glucuronide in hydrolysis with mineral acids (author's transl)]

The behaviour of p-nitrophenol and synthetic p-nitrophenol-glucuronide with mineral acids has been investigated. With sulfuric acid (33%) about 93% of the glucuronide derivative have been hydrolysed; the solution was heated in open vessel for 15 sec. With hydrochloric acid (6%) only about 65% of the conjugated p-nitrophenol have been converted to the free form. No losses were detected, when free p-nitrophenol was treated under the same conditions. Three other methods of hydrolysis have been applied.     

Animal experiments on the detection of an exposure to "chemical mace" (author's transl)]

To answer the question whether a negative result of gas chromatographic blood analysis for components of chemical mace proves that no or at most only slight tear gas exposure can have occurred, animal experiments were carried out. In the blood of 10 guinea pigs, which were exposed to the contents of chemical mace for 1--6 h, the solvants 1,1,2-trichloro-1,2,2-trifluorethane (freon 113) and 1,1,1-trichloroethane could easily be detected--even 23 h after the end of exposure or after a storage of the blood samples for 18 weeks--whereas the lacrimator chloracetophenone (CN) could not be found at all. In vitro experiments showed that CN relatively quickly reacts with components of blood. Therefore, blood samples should be analyzed for CN after withdrawal as soon as possible. In case of inhalation of the contents of chemical mace, i.e., after the comparatively mildest form of CN application, most probably no traces of the lacrimator at all can pass into the blood due to the quick reaction of CN with proteins of the respiratory surface of the lung.
