Remodeling of the extracellular matrix of the liver in mice with BCG-induced granulomatosis after 2-month course of intraperitoneal injections of isonicotinic acid hydrazide, oxidized dextran conjugated with isonicotinic acid hydrazide, dextrazide, and its liposome-encapsulated form manifested in modification of the proteoglycan composition and hydroxyproline fractions associated with changes in hyaluronidase and MMP activities. The antifibrotic effect of dextrazide and its liposome-encapsulated form manifested in reduction of hydroxyproline fractions that reflected the process of collagen synthesis. Administration of isonicotinic acid hydrazide was followed by a decrease in hydroxyproline fractions reflecting collagen synthesis (antifibrotics effect) and degradation (profibrotic effect), which can be explained by its hepatotoxic activity.
在腹腔注射异烟肼、异烟肼偶联氧化葡聚糖、右旋糖酐及其脂质体包封形式2个月疗程后,卡介苗诱导肉芽肿病小鼠肝脏细胞外基质的重塑表现为蛋白聚糖组成和羟脯氨酸组分的改变,这与透明质酸酶和基质金属蛋白酶活性的变化相关。右旋糖酐及其脂质体包封形式的抗纤维化作用表现为反映胶原合成过程的羟脯氨酸组分减少。异烟肼给药后,反映胶原合成(抗纤维化作用)和降解(促纤维化作用)的羟脯氨酸组分均降低,这可由其肝毒性活性来解释。
