Using cd, cu, zn and cr as experimental toxicants and crucian as experimental creature, we employed the environmental biotechniques ( flame atomic absorption spectrophotometry, the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure. through which, we intended to fully and systemically study the toxic influence of heavy metals to fish, and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual, organ, tissue, cell and molecule. thus we tried to provide scientific evidence to establish preventative management measures, avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time
隨后以這幾種重金屬作為實驗毒物,以鯽魚為實驗動物,應用環境生物技術、火焰原子吸收分光光度法、鄰苯三酚自氧
化法、透射電鏡等技術研究了重金屬cu 、 zn 、 cd和cr對鯽魚的急性毒性及其安全濃度評價、混合重金屬在鯽魚幼體組織內的積累和分佈、 cd對鯽魚鰓和肝
臟中sod活性的影響、 cd對鯽魚肝細胞和腎細胞超微結構的影響等,全面和系統地研究了水環境中重金屬暴露對魚類的毒性影響,初步探討了重金屬污染對魚類的個體? ?器官? ?組織? ?細胞? ?分子等各水平層次的影響,為制定漁業生產上預防性的管理措施提供科學依據,及時避免或減輕重金屬污染對水生生態系統造成的損害。
Trial 2, effect of supplemental copper of different type on nutrition and specific immunity of mice - ii the grouping of trialt animal was the same as trial 1, at the first day, second day, third day, one mouse was injected with pha brine fluid for 10mg / kg avoirdupois after weighing in the same time in each repeat, following the 7d, 14d, 21d, 8d feeding period, after weighing, blood was made, wrigh - giemsa coloration, counting the number of lymphocyte female cell and overage lymphocyte, index of immune organ, copper concentration in liver and spleen
試驗二,不同形式銅對小鼠營養與特異性免疫功能的作用-試驗動物分組同試驗一,進入正式試驗期后,在每周第1天、 2天、 3天同一時間每重復選取1隻小鼠,稱重后每天按10mg kg體重肌肉注射一次植物血凝素生理鹽水溶液,並於試驗第7天、 14天、 21天、 28天稱重后尾尖取血,姬姆薩-瑞氏染色,計算t淋巴細胞轉

When the consumption of novel flavored food is followed by internal malaise, such as queasiness, diarrhea, bellyache and so on, animals will decrease or avoid ingesting the food with the same gustatory feature on the subsequent exposures. this type of behavioral change is referred to as conditioned taste aversion ( cta )
動物攝取某種具有新異味覺的食物后,如果導致惡心、嘔吐、腹瀉等內

Yherefore, many researchers have shown great concern with the development of vaccines to against schistosomiasis. at early stage, the research of vaccines of schitosomiasis was centered on dead vaccine and athenuated cercaria of schistosomes while molecular vaccine and athenuated cercaria of schistosomes while molecular vaccine is currently the focus of research with anti - infection protective immunity as its main concern. guan xiaohong and zhao weixian ( 1986 ) certified that the allergen of egg granulonma of schistosoma japonicum might firstly come from gut associated antigen ( gaa ) of schistosomula and adult worm and that daa had cross reaction with soluble egg antigen ( sea ) and membrane associated antigen ( maa ) ; and the gaa of schistosoma japonicum might play a sensitizing role in egg granuloma formation
