Urticaria developed in six patients three to ten days after the intramuscular injection of penicillin, and the condition persisted for from three to fifteen months. The suffering, disability and expense that resulted from the injection indicates that physicians should make certain that the patient who receives penicillin has a true indication for its use. 相似文献

尖镰孢胞外青霉素V酰化酶的产生 总被引:1,自引:0,他引:1
由腐殖土中分离出一株产胞外青霉素V酰化酶的尖镰孢(Fusariumoxysporum),编号FP941。研究了该菌在液体培养基中产胞外青霉素V酰化酶的条件。在以10%麦麸为碳源的培养基中,添加氮源能促进酶的形成。无机氮源优于有机氮源。(NH4)2HPO4的促进效果最佳,草酸铵次之,用量均为1%。为提高产酶量,培养基中添加诱导物是必要的、苯氧乙酸的诱导效果最佳,用量为0.1%,其次是青霉素V,用量为0.3%。最适培养条件为:培养 相似文献
