两种驱虫糖片驱除鞭虫的效果观察

采用甲苯达唑糖片３００ｍｇ，４００ｍｇ２天分服驱除鞭虫，疗毕３周虫卵阴转率分别为７７．１９％和６９．７７％。采用阿苯达唑糖片相同的剂量和治疗方案，虫卵的阴转率分别为５２．０８％和７７．１２％上述所有观察组虫卵减少率在９１．４７～９８．６３％之间，本次观察大多数鞭虫患者均轻度感染，驱出的成虫数量中蟾较少，虫卵阴转率也不十分理想，但虫卵减少率较高，从流行病学的观点看，已大大降低了鞭虫的传播动力，因此，

Selective breeding for the control of nematodiasis in sheep

Genetic manipulation of sheep by selective breeding offers a means to reduce the current reliance on chemotherapy for the control of gastro-intestinal nematodes. Simulated epidemiological studies support this view as, compared to lambs of 'normal' susceptibility, those 'selected' for resistance to Trichostrongylus colubriformis have lower worm burdens and reduced production losses. Considerable genetic variation exists both between and within breeds of sheep, and a number of breeding programmes have demonstrated that selection for animals with heightened levels of resistance to nematodes is feasible. Animals from these selection experiments are currently being used to investigate the nature of this genetic regulation and the economic benefits that can be achieved. An understanding of the mechanisms of resistance, facilitated by having animals with defined extremes of responsiveness, is crucial for studies into the specificity of selection, identification of predictive markers with resistance, and determination of suitable vaccines and vaccination strategies in unselected populations. Immunity plays a major role in host resistance to parasites, and from studies with selected animals, it appears that a broad range of immune responses are under genetic control. Genetic diversity within the parasite population may manifest itself in adaptation to withstand host resistance mechanisms. Such an occurrence could limit the effectiveness of the genetic approach.

Intrauterine contraception with Nova-T and Copper-T-200 during three years

A randomized comparative trial on the clinical performance of two copper-releasing IUDs (Nova-T and Copper-T-200) was performed simultaneously in Denmark, Finland and Sweden. After three years the cumulative pregnancy rate was 1.9 for Nova-T and 5.0 for Copper-T. This difference in efficacy was statistically significant (p < 0.001). Copper-T had a lower expulsion rate (p < 0.05) in the total series but not in postmenstrual insertions. Differences between the two devices in other termination rates were not statistically significant. Analysis according to age and parity demonstrated that the pregnancy rate of Nova-T was lower than that of Copper-T in every age and parity group. The pregnancy rate of Nova-T was not affected by age or parity whereas the pregnancy rate and the expulsion rate of Copper-T decreased with increasing age and parity. The removal rate because of infection decreased markedly after the first year of use for both devices. The cumulative rate of removals for infection during the three years of use was not significantly correlated to age and there was no correlation to parity. The continuation rates increased with age and parity. The continuation rates of nulli- and primiparous women were almost identical with both devices and lower than continuation rates of women with 2 or three or more children. Only 11% of the women were lost to follow-up during 36 months. Nova-T had superior effectiveness in preventing undesired pregnancies when compared with Copper-T. The performance of Nova-T is less affected by age and parity than the performance of Copper-T. The silver core in copper wire gives a prolongation of the life-span for Nova-T. For these reasons, Nova-T appears to meet the requirements for an ideal IUD.     

三部门合作控制医疗保险费用的机制和措施

对于过度上涨的医疗费用实施适度控制是医疗保险制度改革的目标之一 ,也是各级医疗保障部门在实际工作中的难点。从近期来看 ,过高的医疗费用会使刚刚建立而没有积累的医疗保险基金无法实现收支平衡的目标。从长期来看 ,医疗保险的筹资与职工工资收入水平同步变动 ,而医疗费用增长远远超出社会经济和工资收入增长速度 ,在这种情况下 ,任何医疗保险方案都将面临收不抵支的风险。为了化解经济低速增长与费用高速增长之间的矛盾 ,促进医疗保障体制的持续、平稳运作 ,必须大力推进“三项改革” ,建立医疗卫生、药品监督与医疗保障三部门密切合作…
