ジャーナル フリー近年, 緑膿菌を中心とするグラム陰性桿菌によるOpportunistic infectionの増加に伴い, アミノ配糖体剤 (AGs) 使用の機会は増加している。特に, AGsは腎から尿中への移行が極めて良好であり, 基礎疾患を有する難治性の尿路感染症においては, 抗緑膿菌作用を有するAGsが第1選択となる場合も少なくない。本邦では, AGsの投与経路として臨床上筋注だけしか許可されていないが, 欧米では抗緑膿菌作用を有するAGsの静注も許可されている1)。出血傾向のある患者や, 重症例については, 明らかに静注のほうが望ましい投与法と考えられ, 本邦においてもここ数年来AGsの静注投与に関する基礎的, 臨床的検討が行われている2～4)。
今回, 我々は複雑性尿路感染症患者13例を対象として, Micronomicin (MCR) の点滴静注による治療を行い, その臨床効果並びに安全性について検討を加えたので報告する。抄録全体を表示PDF形式でダウンロード (776K) -

ジャーナル フリーSUTHERLAND1) and WEISS et al.7) reported cases of newborn human deaths or GRAY syndrome after overdosage of chloramphenicol. In general, it has been reported that the acute toxicities of drugs are enhanced in immature animals compared with adult animals.
The objective of this study was to determine the LD50 values in infant (5-day-old) and young adult (5-week-old) male and female mice after single subcutaneous and oral administration of MOM, noncrystalline solid and to estimate the toxicity ratio of those LD50 values.
LD50 values of MOM, non-crystalline solid, were more than 5,000mg/kg and the lethal toxicity was the same in infant and adult mice. Toxicity ratios were not obtained.抄録全体を表示PDF形式でダウンロード (441K) -

ジャーナル フリーIn the present acute toxicity studies on MOM, non-crystalline solid, with infant male and female rats (5-day-old) and young adult male and female rats (5-week-old), it is confirmed as follows:
1. LD50 values were estimated more than 5,000mg/kg in both cases of subcutaneous and oral administrations.
2. MOM, non-crystalline solid, did not exhibit any toxic effects similarly as previously reported with infant male and female mice and young adult male and female mice.
3. There might be no definite age difference in toxicity between young and adult rats as LD50 values were estimated more than 5,000mg/kg in independence upon the age.
4. There might be no definite species difference in toxicity between mice1) and rats.抄録全体を表示PDF形式でダウンロード (341K) -

ジャーナル フリーMiocamycin (MOM) is a derivative of midecamycin, a macrolide antibiotic isolated from a culture broth of Streptomyces mycarofaciens. The objective of this study was to determine the effect of MOM on reproductive performance in rats and rabbits. MOM, non-crystalline solid, was suspended in 0.1% CMC solution immediately before use.
In this study, reproductive performance was studied according to the following designs:
1. Fertility test (Segment I) in Wistar rats
2. Teratogenicity test (Segment II) in Wistar rats
3. Peri-and post-natal tests (Segment III) in Wistar rats
4. Behavioral test in rat newborns in Segments II and III
5. Teratogenicity test (Segment II) in New Zealand white rabbits
In conclusion, MOM, non-crystalline solid, might have no teratogenesis and little influence on dams and their fetuses and offsprings.抄録全体を表示PDF形式でダウンロード (8009K)
