Morphological types of ganglion cells in the dog and wolf retina.

The morphological types of ganglion cells in the dog and wolf retina were studied by intracellular staining with Lucifer Yellow. These retinae contain a range of ganglion cell types that closely correspond to those found in cat retina: alpha cells with large somata and large, relatively densely branched dendritic trees; beta cells with medium-sized somata and small, densely branched dendritic trees; and a variety of other types with smaller somata and varying dendritic branching patterns and dendritic field sizes. The correspondence of canine and cat ganglion cell types strengthens the view that there is a common set of ganglion cell types in carnivores. Alpha and beta cell dendritic trees of dog and wolf are monostratified in either the inner or the outer part of the inner plexiform layer, suggesting an on/off dichotomy in the response to light. Dendritic field sizes of dog alpha and beta cells increase from the central area to peripheral retina: alpha cell fields from 160-200 microns to about 1,100 microns diameter, and beta cell fields from 25 microns to about 360 microns diameter. These sizes are quantitatively very similar to those found in cat retina. The close qualitative and quantitative morphological correspondence of cat and dog ganglion cells suggests that they are also functionally very similar. It is likely that dog alpha cells have brisk-transient (Y), and dog beta cells brisk-sustained (X) concentric receptive fields. From the smallest beta cell sizes it is concluded that the visual acuity of the dog may be as good as that of the cat.     

急性白血病形态学与免疫学分型

目的：分析急性白血病形态学分型(FAB分型)与免疫学分型的相互关系。方珐：选择我院2000～2002年确诊的169例初诊急性白血病进行形态学与单克隆检测免疫学分型比较。结果：106例FAB分型为急性髓细胞白血病(AML)，免疫学特征有M3 HLA-DR(-)，M4、M5有CD14( )特征，及有淋系相关抗原表达；63例FAB分型为急性淋巴细胞白血病(ALL)，免疫学分型有单纯髓系4例，B-ALL18例，T-ALL5例，变异型23例，混合型13例。结论：在AML中(除M0、M7)，不如形态学直观、分型仔细。对于ALL病FAB分型不如免疫学分型，对于M0、M7，只有依靠免疫学分型。FAB分型与免疫学分型两者要相互结合，互相补充，才能更好地反映急性白血病的状况，对临床治疗方案的选择及判断预后有重要意义。

弹性义齿修复的临床效果观察

目的：了解弹性义齿修复的临床效果，为临床应用提供参考。方法：152例门诊缺牙患者，制作弹性义齿修复体188件，上颌130件，下颌58件。Kennedy一类缺损修复6件，Kennedy二类缺损修复4件，Kennedy三类缺损修复102件，Kennedy四类缺损修复76件。通过1－4年的观察，从形态和功能、固定和稳定、颜色和美观以及对组织保健判断对义齿的满意程度，并进行临床效果评价。结果：79例95件弹性义齿具有良好的美观效果，颜色满意，感觉舒适，满意和较满意率达100％，Kennedy三、四类缺损修复率为94．74％。弹性义齿对Kennedy一类缺损修复的满意和比较满意率为66．67％；对Kennedy二类缺损修复的满意和比较满意率为50．00％；对Kennedy三类缺损修复的满意和比较满意率为96．15％；对Kennedy四类缺损修复的满意和比较满意率为84．21％。结论：(1)弹性义齿是一种美观、舒适、对基牙预备甚少的可摘局部义齿修复形式。（2）弹性义齿较适合咀嚼压力小而缺牙数目不多的前牙和前磨牙缺失的修复。     

脑梗死OCSP分型和预后

目的了解脑梗死患者OCSP临床分型的构成及不同亚型与预后及复发的关系。方法采用回顾性队列研究,登记2002年1月~2005年6月第四军医大学西京医院神经内科确诊的617例脑梗死患者,按照OCSP标准分型并进行随访,分析各亚型与预后及复发的关系。结果OCSP各亚型构成比分变为:TACI占7.3%,PACI23.3%,POCI6.0%,LACI63.4%,分型与预后明显相关,TACI的预后最差,POCI和LACI预后相对较好,PACI次之,卒中复发与分型无明显相关。结论OCSP分型作为一种脑梗死临床分型方法,可以为脑梗死的预后判断提供参考依据。     

Placental malaria. I. Pathological classification

Pregnant women are more likely to contract malaria than their non-pregnant counterparts. The aim of this study was to develop a simple classification system for the histopathological diagnosis of placental malaria infection applicable to placentas collected in field conditions. The placentas were classified into four groups depending on the presence and disribution of parasites and malaria pigment: active infection, active-chronic infection, past-chronic infection, not infected. The frequency of parasitized placentas (26.4%) was in keeping with the prevalence of placental parasitaemia documented in epidemiological studies. An additional 29.8% placentas showed pigment in fibrin only, indicating pastchronic infection. Chronic placental malaria infection was most common in primigravidae, possibly reflecting ineffective clearance of parasites from the placenta. Seasonal fluctuations between infection categories support progression of placental infection with delayed clearance of pigment from fibrin. The proposed classification system has allowed diagnosis of different categories of placental malaria infection by two independent observers. A stadardized method of diagnosis may enhance understanding of placental pathology and reduced birth weight in malaria infection during pregnancy.     

Axes: Focus of Taxonomy II

A number of persistent issues in the nursing diagnosis community have challenged the ability of one nursing diagnosis taxonomy to account for nursing's practice. The North American Nursing Diagnosis Association (NANDA) Taxonomy Committee, charged with the preparation of one taxonomy for all, has struggled with some of these issues and has initiated dcvelopment of axes. The issues, figuratively speaking, become the axes. The axes are intended to describe the dimensions of the human condition. This article, third in a series of four, describes the process and development of the proposed axes.
