RESUMO
The results of the determination of SACE activity in recent four years were reported. It was found that the levels were 33.5?5.1, 41.6?8.6, 33.4?8.6, 37.2?4.5, 53.6?7.3 and 31.4?13.0 in the healthy persons (37 cases), silicosis (40 cases), lung cancer (30 cases), pulmonary tuberculosis (18 cases), active sarcoidosis (4 cases) and inactive sarcoidosis (3 cases), respectively. The clinical value of the SACE measurement in sarcoidosis was discussed. The results showed that the SACE measurement is helpful to the diagnosis and monitoring of sarcoidosis, because the SACE activity was significantly elevated in most cases of active sarcoidosis, decreased during the stage of remission and elevated again during exacerbation. However, sarcoidosis can not be ruled out even though a normal SACE activity is measured. In addition, the SACE activity can also be elevated in the other pulmonary or systemic diseases, but the differentiation of these diseases from sarcoidosis is not difficult clinically. The SACE measurement can not be taken as a predictor of the prognosis of sarcoidosis.
RESUMO
12 cases of severe pulmonary infection were treated with ceftizoxime, one of cepha-losporins of the third generation. Clinical observation and pharmacokinetics were carried out. The result showed that intravenous infusion was the best route of drug administration. It had the advantages of high serum concentration and prolonged maintenance of serum level. 1 gram of ceftizoxi-me, two times a day, was enough for most pathogens except Pseudomonas aeruginosa.
