Abstract
To compare left ventricular filling variables as derived by transmitral pulsed Doppler echocardiography (tpDE) and hemodynamic variables as assessed at right heart catheterization (RHC), 104 ICU patients (64 male, 40 female) aged 26 to 73 yr (mean 54.6 +/- 10.3) without valvular heart disease were examined. Simultaneously with RHC, transmitral flow velocity profiles were obtained by tpDE, and the ratio of the velocity-time integrals of late diastolic active (A wave) and early diastolic passive inflow into the left ventricle (E wave) was calculated (A/E ratio). Invasively determined pulmonary capillary wedge pressure (WP) ranged from 3 to 36 mm Hg (median 13.35, 5%/95% 6/31 mm Hg). Linear regression analysis showed a highly significant correlation between the A/E ratio and WP (r = .98, p less than .001, standard error of the estimate [SEE] = 0.10). The A/E ratio also correlated with other hemodynamic variables such as cardiac output (r = -.68, p less than .001, SEE = 0.33), cardiac index (r = -.74, p less than .001, SEE = 0.31), and stroke volume index (r = -.68, p less than .001, SEE = 0.34). The interobserver agreement (derived by intraclass correlation analysis between two examiners) on the A/E ratio was high (r = .95, p less than .001, n = 26). We conclude that WP can be accurately determined noninvasively by tpDE. For the assessment of systolic ventricular function, tpDE is of limited diagnostic value.

Abstract
An immunomorphometric study was performed on bone marrow biopsies from 40 patients with primary osteomyelofibrosis--OMF, (agnogenic myeloid metaplasia) by employment of a monoclonal antibody against glycoprotein IIIa (Y2/51) to determine the number of pro-megakaryoblasts. Specimens from 15 individuals without any hematological disorder served as controls. With reference to the pertinent literature on megakaryocyte precursors and following a pilot study on corresponding smears, in tissue sections pro-megakaryoblasts were characterized by a size of 42.1 +/- 2.6 microns 2 (diameter 7.5 +/- 0.3 microns). In comparison with controls, in OMF no relevant increase in the number of pro-megakaryoblasts per square and cubic millimeter bone marrow was evaluable. The relative frequency of these precursors was significantly reduced due to an increase in the total amount of conspicuously large and abnormal megakaryocytes. Statistical analysis failed to reveal any correlations between counts for pro-megakaryoblasts or the total number of Y2/51--positive megakaryocytic elements with the density of argyrophilic fibers (determined by morphometry) or the platelet values. Our findings imply that in OMF the marked increase in circulating progenitor cells of the megakaryocyte lineage may be generated by extramedullary, probably splenic hematopoiesis. Moreover, the evolution of medullary fibrosis is thought to be associated with the striking predominance of large atypical, possibly overaged and hyperpolyploid megakaryocytes and not with an increase in precursor cells.

Abstract
On routinely processed trephine biopsies of the normal human bone marrow derived from 15 patients, immunostaining with a monoclonal antibody against platelet glycoprotein IIIa (Y2/51) and morphometric measurements were performed for the determination of megakaryocyte precursor cells. Based on cell sizes and on comparison with (1) specimens stained by the periodic acid-Schiff reaction and (2) smears, the smallest elements clearly identifiable as belonging to the megakaryocyte series were classified as promegakaryoblasts. Promegakaryoblasts had a frequency of 1.7/sq mm and 140/cu mm of bone marrow and constituted about 8% of the total positively stained megakaryocytic elements; they were characterized by a size of 41.5 sq microns, a diameter of 7.7 microns, a high nuclear-cytoplasmic ratio (0.32) and a nearly circular outline of their nuclear and cellular perimeters.

Abstract
A morphometric study was performed on trephine biopsies of bone marrow in patients with chronic myeloid leukemia (CML) accompanied by myelofibrosis and in so-called primary (idiopathic) osteomyelofibrosis/-sclerosis (OMF) to evaluate distinctive features of megakaryopoiesis. The periodic acid Schiff reaction (PAS) and a monoclonal antibody against glycoprotein IIIa were employed for the identification of megakaryocytes including precursor cells and Gomori's silver impregnation to determine the density of argyrophilic fibers. All patients with CML revealed a slight to moderate degree of medullary fibrosis and were compared with early hyperplastic stages of OMF showing an identical fiber count. Statistical analysis disclosed that distinctive features existed between these two subgroups. Amongst these variables were sizes of megakaryocytes and corresponding nuclei, frequency of bare nuclei, emperipolesis and numbers of isolated nuclear fragments as well as the circular deviation of cell and nuclear perimeters. Immunomorphometry also included immature elements (pro- and megakaryoblasts) of the megakaryocyte series. Consequently higher cell counts were calculable in both groups combined with smaller sizes and a more rounded aspect of nuclei. However, following immunostaining, significant differences in several megakaryocytic parameters (frequency, size, shape of nuclei) were still demonstrable between CML and OMF cases.

Abstract
Echocardiography was performed before and after inhalation of 0.9 mg nicotine in 21 patients (6 women and 15 men with a mean age of 51.8 [38-73] years). All of them had angiographically confirmed coronary heart disease (stenosis greater than 50%) and smoked 20-50 cigarettes daily for at least 5 years. In addition, left ventricular filling parameters were determined by transmitral pulsed Doppler ultrasonography. In this technique the flow profile across the mitral valve is divided into the passive, early diastolic inflow (E wave) phase and the active, late diastolic inflow phase caused by atrial contraction (A wave). Isovolumetric relaxation time was measured by simultaneous M-mode recordings over the aortic and mitral valves. The following significant changes were noted after the dose of nicotine (medians; one-sided Wilcoxon test; P less than 0.05): peak velocity of the E wave decreased from 43 to 34.4 cm/s; the ratio between A and E wave peak velocities increased from 1.02 to 1.37; the velocity/time integral of the E wave decreased from 4.77 to 3.57 cm; the ratio between the velocity/time integrals of the A and E waves rose from 0.66 to 1.15; isovolumetric relaxation time increased from 90 to 121 ms. - In cigarette smokers with coronary heart disease, acute administration of nicotine hence caused a decrease in early diastolic transmitral blood flow and an increase in isovolumetric relaxation time. These changes point to significant impairment of left ventricular diastolic function.

Abstract
A histomorphometric (planimetric) study was performed on trephine biopsies of the bone marrow taken at presentation from 65 patients (31 males and 34 females, with a median age of 48 years) with chronic myeloid leukemia (CML). Specimens from 20 patients (9 males and 11 females, with a median age of 53 years) without any hematologic disorders served as controls. Of the various histologic variables tested, only the counts of neutrophilic granulocytes per 1 sq mm, the ratio of granulocytopoiesis to megakaryopoiesis and the density of reticulin (argyrophilic) fibers revealed a significant correlation with the prognosis. The CML patients were separated into two groups with different survival patterns. Group I (34 patients with a median survival of 24 months) mostly contained cases with the so-called "megakaryocytic subtype" of CML, which is accompanied by variable degrees of fibrosis; group II (31 patients with a median survival of 36 months) mainly contained cases with the "granulocytic subtype," which is not accompanied by myelofibrosis. Among the morphometric parameters, a positive correlation existed between the megakaryocyte count and the reticulin fiber density, which underlines the important role of that cell lineage in fibrillogenesis. There were multiple interrelationships between the histomorphometric variables and the laboratory data. Consequently, multivariate regression methods (using Cox's proportional hazards model) were applied to assess the relative predictive value of the patient characteristics for survival. The derived prognostic model divided the patients into two risk groups, with median survivals of 14 and 41 months, respectively. In order of their entry into the regression model, these variables were percentage of neutrophils in the differential blood count, amount of granulopoiesis, liver size, percentage of peripheral myeloblasts and density of reticulin fibers in the bone marrow. In comparing the two patient groups, based on bone marrow histomorphometric parameters, this model revealed that two of those factors (amount of granulopoiesis and density of reticulin fibers) had a significant correlation with the prognosis.

Abstract
An immunomorphometric study was performed on trephine biopsies of the bone marrow in 41 patients with chronic myeloid leukemia (CML) to determine number and size of megakaryocytic precursor cells (pro- and megakaryoblasts). For specific staining, a monoclonal antibody against platelet glycoprotein IIIa (Y2/51) was employed which is applicable on routinely fixed and paraffin embedded tissue. In comparison with control specimens from 15 patients, in CML morphometric analysis revealed an increase in the total amount of megakaryocytes per square and cubic millimeter marrow tissue, but particularly in patients with thrombocythemia. Moreover, a non-disorderly expansion of the megakaryocyte precursor pool was recognizable by showing a relative frequency of pro- and megakaryoblasts in congruence with the normal value. In this context a significant correlation between the counts for Y2/51-positive megakaryocytic elements and promegakaryoblasts with the corresponding platelet values was encountered. The more mature stages of megakaryopoiesis (pro- end megakaryocytes) disclosed a relevant shift to smaller cell forms with rounded cell perimeters and a more compact aspect of their nuclei. Additionally, in 6 patients with CML, evolution into a subacute and manifest (micro)-megakaryoblastic transformation accompanied by myelofibrosis could be demonstrated by a retrospective review of file material.

Abstract
To determine the number of megakaryocyte precursors (pro- and megakaryoblasts), an immunomorphometric study was performed on paraffin-embedded trephine biopsies of the bone marrow using a monoclonal antibody against platelet glycoprotein IIIa. Eighteen control specimens from patients with no evidence of any hematological disorder and a normal platelet count were selected and assessed together with the same number of specimens from patients with reactive thrombocytosis, polycythemia vera rubra (P. vera) or primary (essential) thrombocythemia (PTH). A strikingly proportionate increase in early megakaryocytes occurred in all patients enrolled in this study, compared with the controls. Moreover, there were no significant correlations between counts for precursors or total megakaryocytes per square millimeter of bone marrow with the corresponding values for platelets. This indicates that despite an orderly increase in immature forms in the bone marrow, the number of platelets circulating in the blood is influenced by other additional factors, such as the expanded platelet pool in the enlarged spleen. The non-disproportionate expansion of megakaryocyte precursors extends previous findings on progenitor cells of this lineage in vitro, particularly in PTH. Histological evaluation of the bone marrow of patients with P. vera and PTH indicated that megakaryopoiesis proceeded to the production of appropriate mature forms with no obvious excess of very small or blastic elements.

Abstract
In 165 patients with chronic myeloproliferative disorders (CMPD) a morphometric and histochemical study was performed on trephine biopsies of the bone marrow to elucidate osseous remodeling by assessment of trabecular bone area (planimetry) and number of osteoclasts. Osteoclastic elements were identified by the tartrate-resistant acid phosphatase method. In addition to control specimens (n = 20) subtypes of CMPD included chronic myeloid leukemia (CML, n = 65), primary (essential) thrombocythemia (PTH, n = 25), polycythemia vera rubra (P. vera, n = 25) and agnogenic myeloid metaplasia (AMM, n = 50). AMM was discriminated into a so-called early hyperplastic stage without gross myelofibrosis (n = 19) and an overt or advanced stage showing fibro-osteosclerotic changes (n = 31). Total area of trabecular bone and counts for osteoclasts (uni- and multi-nucleated cells as well as a-nuclear cytoplasmic fragments) were not significantly increased in CML, PTH, P. vera and in the initial hypercellular stages of AMM. In contrast to these results, in advanced stages of AMM there was a significant increase in total bone area associated with a high count for all osteoclastic elements and apparently also an increased number of osteoblasts. It is speculated that the marked increase in osteoclastic-osteoblastic elements in late stages of AMM possibly reflects an imbalance of calcitriol (1.25-dihydroxyvitamin D 3) on skeletal homeostasis. This abnormal osseous remodeling may be mediated by the atypical megakaryocytic proliferation in this disorder, which is always a conspicuous feature of bone marrow biopsies.

Abstract
A histomorphometric analysis was performed on trephine biopsies of the bone marrow in 55 patients with chronic myeloproliferative disorders (CMPDs) and marked thrombocytosis (platelet count exceeding 600 x 10(9)/l). This study aimed at discriminating primary (essential) thrombocythaemia (PTH) from the various other subtypes of CMPDs presenting with thrombocytosis. Following the diagnostic requirements postulated by the Polycythemia-vera-Study-Group for PTH and polycythaemia vera rubra (P.vera) and the generally accepted criteria for the establishment of chronic myeloid leukaemia (CML) and agnogenic myeloid metaplasia (AMM), our cohort of 55 patients was divided into the following subgroups: CML (16 cases), P.vera (11 cases), AMM (13 cases) and finally PTH (15 cases). Histomorphometric measurements revealed that PTH was distinguishable from the other subtypes of CMPDs with respect to several histological variables: patients with PTH had a normal amount of neutrophilic granulo- and erythrocytopoiesis as well as a non-increased content of reticulin (argyrophilic) fibers in contrast to the findings in CML, P.vera and of course AMM. Moreover, sizes of megakaryocytes and their nuclei were significantly greater in PTH and internalization of haematopoietic cells (emperipolesis) was more frequently encountered in comparison with the other subtypes of CMPDs. Deviation of the circular perimeter of megakaryocyte shape was most prominently expressed in CML and AMM, and consequently generated an increased number of a-nuclear cytoplasmic fragments. In contrast to this feature aberration of the nuclei from a circular outline occurred in a less pronounced way in CML, but was excessive in P.vera, AMM and PTH. Our morphometric evaluation demonstrates that certain histological features may serve as a valuable aid in discriminating PTH from the other occasionally thrombocythaemic subtypes of CMPDs.

Abstract
A morphometric analysis was performed on trephine biopsies of the bone marrow to identify atypical megakaryocyte proliferation following PAS staining and the immunohistological demonstration of factor VIII. This study includes nine patients with a megakaryoblastic crisis in chronic myeloid leukemia (CML), four with acute megakaryoblastic leukemia (AM) and three with myeloid dysplasia later evolving into overt acute leukemia. Comparison and statistical evaluation of the PAS reaction with anti-factor VIII staining reveals that the latter technique not only facilitates the recognition of immature and abnormal megakaryocytes, but leads to a significantly increased count for all megakaryocytic elements in the bone marrow. Thus our retrospective investigation of routinely processed and paraffin-embedded trephine biopsies shows that the diagnosis of a megakaryoblastic crisis in CML as well as AM may be easily established with the aid of the anti-factor VIII method. In all cases of megakaryoblastic proliferation in CML and AM, the appearance of blasts was associated with moderate to pronounced myelofibrosis which could be also determined by morphometry.
