血液采集和单采期间不良反应的发生率:一项单中心研究

通常认为异体血液采集的献血者发生不良反应和损伤的发生率低,但自体献血者不良反应发生率的数据则自相矛盾,单采不良反应的发生率和预测献血者反应的因素还知之甚少。 本文分析了作者输血中心1998年1月到2001年6月记录的血液和单采献血者的所有不良反应。作者对发生不良反应与未报告任何不良反应的献血者之间的人口统计学和身体特征进行比较,以便确定不良反应预测因素的存在。     

RELATIONSHIP BETWEEN SOME REPRODUCTIVE PARAMETERS AND BIOCHEMICAL PROPERTIES OF BLOOD SERUM IN RAMS

The objective of the present study was to describe the relationship between some reproductive parameters, hormonal levels, and some biochemical properties of blood serum in rams under the Afyon province conditions. The total protein and globulin were positively (P?<?0.01) correlated with sperm motility and sperm concentration in all of rams. Total lipid was negatively (P?<?0.05) correlated with sperm motility and concentration in Daglic, and it was positively (P?<?0.01) correlated with percentage of abnormal spermatozoa in Chios rams. Total lipid and cholesterol was positively (P?<?0.01) correlated with triiodothyronine in all of rams and was negatively (P?<?0.05) correlated with testosterone in Daglic rams. Percentage of abnormal spermatozoa were negatively (P?<?0.01) correlated with alanine amino transaminase (ALT) level, but were positively (P?<?0.01) associated with aspartate amino transaminase (AST) level and AST/ALT ratio in all of rams.     

儿童输注ABO主侧不合血小板的效果弱于输注血型相合的血小板

由于血小板只有5天的保存期,库存压力导致经常输注ABO血型不合的血小板.为了避免血小板过期,首先输注的是库存时间最长的血小板,包括输注ABO血型不合的血小板.AABB和英国血液学标准委员会建议,输注红细胞时必须要求ABO主侧相合,而输注血小板并没有要求ABO血型匹配.     

Labial Adhesion with Acute Urinary Retention Secondary to Bartholin's Abscess

Labial adhesions are usually seen in early childhood or in the postmenopausal years, but this clinical entity is rarely seen in the reproductive years. We report a case of labial adhesion with acute urinary retention secondary to Bartholin's abscess in a reproductive‐aged woman with normal menstrual periods. We emphasize the possible occurrence of labial adhesion following Bartholin's abscess in the reproductive years with normal estrogen levels.     

Androgen receptor YAC transgenic mice carrying CAG 45 alleles show trinucleotide repeat instability

X-linked spinal and bulbar muscular atrophy (SBMA) is caused by a CAG repeat expansion in the first exon of the androgen receptor (AR) gene. Disease-associated alleles (37-66 CAGs) change in length when transmitted from parents to offspring, with a significantly greater tendency to shift size when inherited paternally. As transgenic mice carrying human AR cDNAs with 45 and 66 CAG repeats do not display repeat instability, we attempted to model trinucleotide repeat instability by generating transgenic mice with yeast artificial chromosomes (YACs) carrying AR CAG repeat expansions in their genomic context. Studies of independent lines of AR YAC transgenic mice with CAG 45 alleles reveal intergenerational instability at an overall rate of approximately 10%. We also find that the 45 CAG repeat tracts are significantly more unstable with maternal transmission and as the transmitting mother ages. Of all the CAG/CTG repeat transgenic mice produced to date the AR YAC CAG 45 mice are unstable with the smallest trinucleotide repeat mutations, suggesting that the length threshold for repeat instability in the mouse may be lowered by including the appropriate flanking human DNA sequences. By sequence-tagged site content analysis and long range mapping we determined that one unstable transgenic line has integrated an approximately 70 kb segment of the AR locus due to fragmentation of the AR YAC. Identification of the cis - acting elements that permit CAG tract instability and the trans -acting factors that modulate repeat instability in the AR YAC CAG 45 mice may provide insights into the molecular basis of trinucleotide repeat instability in humans.
