Erythrocyte protoporphyrin test for occupational lead exposure.

Determination of erythrocyte protoporphyrin levels was performed in workers who are occupationally exposed to lead. The level of erythrocyte protoporphyrin was easily measured with microsamples of blood by utilizing a fluorescent assay. The log of erythrocyte protoporphyrin level was closely correlated to blood lead level (r = .72) in lead-exposed workers. The erythrocyte protoporphyrin test is especially useful in the detection of mild increases in blood lead concentration under conditions of occupational exposure.

Recovery of catalase activity after inhibition with aminotriazole in acatalasemia mice.

The kinetics of catalase synthesis and degradation were determined in acatalasemia and normal mouse livers during recovery of catalase activity after inhibition with aminotriazole. Catalase turned over with a half life of 10.0 hr in acatalasemia mice and of 19.2 hr in normal mice. The rate of catalase synthesis (Ks) was 0.168 (PU/mg protein/hr) in acatalasemia mice and 0.271 in normal mice. The rate of catalase degradation (KD) was 0.069 and 0.036 per hour in acatalasemia and normal mice, respectively.

[Characterization of Mycoplasms isolated from imported nonhuman primates (author's transl)].

Mycoplasms were isolated from 35 (16%) of 215 specimens collected from 20 crab-eating monkeys (Macaca irus), 9 green monkeys (Cercopithecus aethiops) and from 9 common squirrel monkeys (Saimiri sciurea). All these animals had been imported from South-East Asia, Africa and South America being apparently healthy. A total of 38 large and 20 small colony-mycoplasma strains were isolated from the nasal and oral cavity, urethra, vagina and rectal feces. The large colony-mycoplasmas could be differentiated into 5 groups on the basis of their biological and serological characteristics. Six and 7 of them were identified as M. orale 2 and M. salivarium, respectively. Twenty strains were clearly distinguished not only from M. orale 2 and M. salivarium, but also from such arginase positive species as M. orale 1, M. fermentans, M. hominis, M. arthritidis, M. maculosum and M. gateae. These were divided into 2 groups, comprising 9 and 11 strains, respectively, by growth inhibition as well as various biological tests. The remaining 5 strains were not identified serologically. The small colony-mycoplasmas were found to be urease-positive and appeared to be T-mycoplasmas, while not examined serologically.
