平角涡虫(Planocera reticulata)脑神经节胆碱酯酶的组织化学定位

研究了平角涡虫（Ｐｌａｎｏｃｅｒａｒｅｔｉｃｕｌａｔａ）脑神经节胆碱酯酶的组织化学定位．结果表明,胆碱酯酶阳性细胞分别分布于脑神经节的吻端腹侧面、前腹侧面、中央腹侧面和后背侧面的细胞层中,各阳性细胞在脑神经节中均为左右对称分布．前腹侧面阳性细胞的突起向背内侧延伸,经交叉后进入对侧纤维网中;中央腹侧面阳性细胞的突起向中线延伸形成联系;后背侧阳性细胞的突起向腹外侧延伸进入同侧纤维网中．神经节中央的神经纤维网中具有丰富的阳性纤维,前部反应较强,后端反应较弱．由脑神经节发出的各神经干均呈胆碱酯酶阳性反应．

中药“保健增乳乐”对围产期奶牛血液生化指标的影响

试验选用30头干奶牛随机分成试验Ⅰ组、Ⅱ组及对照组(Ⅲ),观察中药“保健增乳乐”对围产期奶牛血液生化指标的影响。在此基础上,异地选择10头干奶牛随机分成试验组(Ⅰ)和对照组(Ⅱ)进行了重复试验。结果显示:中药“保健增乳乐”能显著地降低产后奶牛血清谷草转氨酶(SGOT)、血清γ—谷氨酰转肽酶(Sγ—GT)、血清碱性磷酸酶(SALP)的活性(P<0.05),血清酮体含量(KB)、血清甘油三酯(TG)含量显著减少(P<0.01)。血糖(G)含量升高(P<0.05)。血清钙、无机磷的含量维持正常水平。结果显示中药“保健增乳乐”能有效地改善围产期奶牛的肝脏功能,维持奶牛的正常代谢,预防奶牛围产期的营养代谢性疾病。     

Going to Pieces: Paul Monette and the Fragments of the Tribe

Author of the highly acclaimed Borrowed Time: An AIDS Memoir (1988) and winner of the 1992 National Book Award for his autobiography Becoming a Man: Half a Life Story, Paul Monette died of complications from AIDS in Los Angeles on February 12, 1995. His most recent work, Last Watch of the Night: Essays Too Personal and Otherwise (1994), is his third volume in a trilogy of autobiographical writing on growing up gay, coming-out, and living with AIDS. A graduate of Phillips Academy and Yale University, Monette received a number of awards for his writing and his work as an outspoken voice in the battle against AIDS, including the National Book Award, three Lambda Literary awards, the PEN Center West Freedom to Write Award, and three honorary doctorate degrees, from Wesleyan University, the City University of New York, and the State University of New York at Oswego. A memorial service was held for Monette on Sunday, February 19, 1995, at the Directors Guild of America on Sunset Boulevard in Los Angeles. Paul Monette was 49.     

Modeling household fertility decisions with generalized Poisson regression

This paper models household fertility decisions by using a generalized Poisson regression model. Since the fertility data used in the paper exhibit under-dispersion, the generalized Poisson regression model has statistical advantages over both standard Poisson and negative binomial regression models, and is suitable for analysis of count data that exhibit either over-dispersion or under-dispersion. The model is estimated by the method of maximum likelihood. Approximate tests for the dispersion and goodness-of-fit measures for comparing alternative models are discussed. Based on observations from the Panel Study of Income Dynamics of 1989 interviewing year, the empirical results support the fertility hypothesis of Becker and Lewis (1973).
