Twelve sheep, divided into two groups of 6 animals each, were used. The first (test) group was offered herbazin -50 with the feed in the course of 90 days after which the animals were infected via the joints with Corynebacterium pyogenes. The second (control) group was also infected with the same pathogen in the same way. During the time the preparation was given and 30 days post infection the animals were kept under observation, following up their clinical, condition, and the occasional morphological and biochemical changes taking place in the blood and the immunobiologic responsiveness. It was found that sheep treated with herbazin -50 with a following infection with Corynebacterium pyogenes raised their blood levels of sugar, total protein, potassium, sodium, magnesium, SGOT, SGPT, and manifested an increased ESR, and lower calcium, inorganic phosphorus, carotene, vitamin A, and cholesterine serum level. It was also established that surgical infections brought about through such introduction of C. pyogenes developed much more rapidly and ran a much more severe course in sheep after the preliminary treatment with herbazin -50. It is believed that they emerged after suppressing the immunologic responsiveness with the use of the preparation.
选用12只绵羊,分为两组,每组6只。第一组(试验组)在90天内随饲料投喂herbazin -50,之后通过关节感染化脓性棒状杆菌。第二组(对照组)也以同样的方式感染相同病原体。在投喂制剂期间以及感染后30天内,对动物进行观察,跟踪其临床状况、血液中偶尔发生的形态和生化变化以及免疫生物学反应。结果发现,用herbazin -50处理后再感染化脓性棒状杆菌的绵羊,其血糖、总蛋白、钾、钠、镁、谷草转氨酶、谷丙转氨酶的血液水平升高,血沉加快,血清钙、无机磷、胡萝卜素、维生素A和胆固醇水平降低。还发现,在先用herbazin -50进行预处理后,通过这种方式引入化脓性棒状杆菌引起的外科感染在绵羊身上发展得更快,病程更严重。据信,这些感染是在使用该制剂抑制免疫反应后出现的。
