导入AGPase基因的转基因可育水稻及其经济性状的研究

以农杆菌介导法将淀粉合成关键酶AGPase(腺嘌呤二磷酸葡萄糖焦磷酸化酶）基因导入云南地方优质水稻合系35，38，39，41，42中，获得了大量的可育转基因植株。PCR扩增检测，外源基因已稳定整合进水稻基因组中。大量的农艺性状及淀粉含量研究表明，转基因水稻种子的千粒重比对照明显提高，但总淀粉含量没有显著变化。

祁连山水源涵养林综合效能的计量研究

以马克思级差地租理论,建立了祁连山水源涵养林综合效能的评价模型:E=E_d+E_e+E_s;以E与生产投资I的比值为计量水源林的效能指数T,T=E/I。并以祁连山寺大隆森林生态定位研究站实测资料和社会调查数据为计量评价参数,确定其经济评价指标体系和计量系统。结果表明:祁连山水源涵养林综合效能指标为11.93;其中生态效能和社会效能分别是直接经济效能的4.51倍和6.05倍。说明祁连山水源涵养林现行的保护、发展和综合利用的经营方针是正确的。建议河西各受益部门应按水资源效能总收入的0.5％缴作水源林再生产费,以确保国民经济建设的长远发展。     

犬瘟热病毒的静水压灭活

以250MPa的静水压力对犬瘟热病毒（CDV）处理30min之后，CDV被灭活，由其制成的灭活疫苗诱导犬产生中和抗体的能力明显优于传统的福尔马林灭活疫苗，免疫保护率达90％。电镜观察显示，经不同程度静水压力处理后的CDV粒子均发生变形，表面呈现凸起，但CDV H基因部分片段的RT－PCR扩增结果揭示，高达510MPa的静水压力作用30min也未能使其基因片段受到破坏。     

国外松芽流脂病发生与防治

近年来,浙江省局部地区国外松纯林受芽流脂病危害较为严重.通过定点现察、分离培养、光镜检查、电镜现察、微量元素测定和用硼砂防治罹病松树等方法,基本查清国外松芽流脂病在浙江省的发生情况,明确了国外松芽流脂病的3种症状顶芽枯死型、丛枝型和枯梢型.国外松芽流脂病是由于松树自身和土壤中的微量元素--有效硼含量不足引起的生理性病害.用喷洒3.0g@kg-1或5.0g@kg-1硼砂溶液防治该病效果显著,防治区病情指数与对照相比平均下降38.5,松树的年平均高生长量也比对照大14.8cm.表4参4     

Investigation of Cervical Patency and Uterine Appearance in Domestic Cats by Fluoroscopy and Scintigraphy

The cervical patency of six domestic female cats was monitored under sedation by infusion of contrast medium (Omnipaque) into the cranial vagina during early oestrus, mid‐oestrus, late oestrus and interoestrus or a radiopharmaceutical (^99mTc‐HSA) during mid‐ and interoestrus in a non‐ovulatory oestrous cycle. The transport of the contrast medium or the radiopharmaceutical through the cervix and within the uterine horns was observed under fluoroscopy and with the aid of scintigraphy. In three of the queens, transcervical transport of contrast medium was demonstrated in all stages of oestrus, in one queen during mid‐oestrus, late oestrus and 1 day after oestrus, and in two queens only during late oestrus. The relations between the cervical patency to the contrast medium and the oestrous behaviour, cornification of the vaginal cells and the serum oestradiol‐17β concentration were evaluated, and a relationship was found between the cervical patency and the degree of vaginal cornification. Transcervical transport of the radiopharmaceutical was observed in three queens during mid‐oestrus. When the cervix was open, hysterography under a fluoroscope and hysteroscintigraphy were performed. The fluoroscopic and scintigraphic recordings revealed the patterns of the uterine contractions during oestrus in both ascending and descending directions, and the movement of the uterine contents back and forth between the uterine horns. The hysterograms were classified according to the shape of the uterine horns and the appearance of the endometrial lining. Spiral‐shaped uterine horns with a smooth inner contour were observed in two queens, and a corkscrew appearance with irregular filling defects in the uterine lumen was shown in two queens that had developed subclinical cystic endometrial hyperplasia. These findings demonstrated that fluids or particles deposited in the cranial vagina of the cat can be transported into the uterus during some stages of the oestrous cycle. The fluoroscopic and scintigraphic techniques developed in this study may be further modified to permit more detailed studies of uterine contractile patterns and sperm transport in the feline female reproductive tract. Hysterography proved useful to diagnose uterine disease. The information on cervical patency is of value also for the development of techniques for artificial insemination in this species, and should be studied also in the ovulatory cycle.     

辛夷油的药理学研究

向大白鼠胸腔注入角叉菜胶诱发胸膜炎,8h后处死动物，测定其胸腔渗出液中白细胞数、蛋白质及前列腺素E2（PGE2）的含量，体内白细胞介素1（IL-1）和肿瘤坏死因子（TNF）的含量。结果显示，事先灌服辛夷油的试验组动物，其胸腔渗出液中白细胞数、蛋白质和PGE2的含量均显著小于模型对照组；IL-1和TNF的含量也明显小于模型组，说明辛夷油能抑制炎症介质的产生，具有抗炎效应。
