Abstract
The surface features of circulating cells from 5 patients with typical Sezary's Syndrome (SS) are described using scanning electron microscopy (SEM). Sezary cells prepared by different methods, with and without prior fixation in cell suspension, showed similar surface architectures. SS cells were mostly spherical and moderate to markedly villous in appearance, and in this respect, resembled the majority of circulating lymphocytes from patients with chronic lymphocytic leukaemia (CLL). A proportion of cells were larger and more irregular in shape while others had small extensions of cytoplasm resembling small uropods with clusters of polarised microvilli. Despite the latter findings, most SS cells cannot be distinguished from CLL cells on the basis of their surface architecture under the SEM.

Abstract
Mononuclear cells from hairy cell leukemia have been studied in three cases by ultrastructural immunocytochemistry. Cells have fairly detectable surface immunoglobulins, without monoclonal distribution however. In addition these cells have a peroxidatic activity which is revealed in the perinuclear space and strands of endoplasmic reticulum.

Abstract
The distribution of the A receptors was studied among 'agglutinated' and 'free' populations of A variant RBC (A3, AX, Aend) known to be either partially or weakly agglutinated by human anti-A reagents. Following separation of the red cell populations and disaggregation of the clumps by mild treatment with soluble blood group substances, it was shown after appropriate controls, that among A3 ARBC, the 'agglutinated' RBC have at least five times as 'free' RBC, these latter however being strongly A positive. The differences between the A antigenic content of the AX RBC were less pronounced. The most striking result was obtained with the Aend RBC, where two populations are clearly demonstrated; the first, including 5-10 per cent of the RBC, strongly agglutinates with anti-A and contains erythrocytes of high antigenic content (140,000 A receptors per cell). The second, including the majority of RBC could not be differentiated from the control O RBC. A wide heterogeneity of antibody binding capacity of the various populations of A3, AX and Aend red cells, was also demonstrated following ultrastructural examination by immunoelectron microscopy with peroxidase-conjugated antibodies. Such study reveals furthermore an heterogeneity of labelling from one cell to another in the same population of red blood cells. Comparison of 'week A' RBC and O RBC enzymatically converted into A RBC, demonstrates a similar pattern of reactivity between these cells, and supports the general relationship between antigen site density and red cell agglutination. It is concluded that the typical pattern of agglutinability of A3 and AX RBC arises both from their heterogeneous antigenic content and from the occurrence of an antigenic threshold below which red cells become non-agglutinable. The typical mixed-field agglutination pattern of Aend RBC merely reflects the occurrence of a probably true dual population of RBC. Finally, the mechanisms of inheritance of such well-known Mendelian characters, enabling the production of highly heterogeneous blood cell populations in the same individual, remains to be elucidated.

Abstract
The degrees of autolysis attained by five different genera of filamentous fungi during an incubation period of 60 days, under the same culture conditions were: 87.3% for Penicillium oxalicum; 65.9% for Neurospora crassa; 62.7% for Polystictus versicolor; 51.7% for Aspergillus niger and 23.5% for Nectria galligena. N. crassa, A. niger and P. versicolor reached the end of the autolysis during this incubation period (60 days), whereas P. oxalicum and N. galligena did not. The excretion of the lytic enzymes beta-N-acetylglucosaminidase, beta -1-3 glucanase, chitinase, invertase and acid phosphatase into the culture medium during growth and autolysis was investigated. The excretion of these enzymes was consistent with the degree of autolysis reached, the maximum excretion belonging to P. oxalicum and the minimum to N. galligena. The N. crassa invertase was excreted into the culture liquid at levels very much higher than the other enzymes studied, and at levels very much higher than the invertases excreted by the other fungi.

Abstract
A and A1 antigen were detected on human blood erythrocytes by immunoelectron microscopy using peroxidase-conjugated antibodies. Cells were obtained from various normal A subgroups, including rare weak A phenotypes and infant (cord blood) samples. Erythrocytes were fixed prior to incubation with specific reagents. The detection of surface antigens was carried out by an indirect method involving anti-A and anti-A1 antibodies and conjugated anti-immunoglobulin antibodies. The surface labelling was seen as a diffuse dense layer. Haemperoxidase-like activity resulted in a faint background which did not interfere at the level of ultrathin sections, with surface staining due to exogeneous peroxidase. The most significant finding was the existence, in a given sample, of several populations of cells as revealed by their antibody-binding capacity. The distribution of the various populations varied from one sample to another according to its subgroup. The progressive weakening of phenotype expression which characterizes the various subgroups from A1 to A weak was paralleled by a decreasing number of "antigen rich" cells, which were still detectable in weak phenotypes as a minor population. This study confirms that a given normal phenotype in fact represents a mixture of antigenically different populations of erythrocytes.

Abstract
Surface associated immunoglobulins (s.Ig) have been detected on human lymphocytes, in normal individuals and in disease, by an immunoelectron microscopic method using peroxidase-labeled antibodies. Experiments have been carried out on fixed cell suspensions, in order to avoid membrane alterations induced by anti-immunoglobulin antibodies. Normal human blood B lymphocytes have a villous surface. However this relationship between microvilli and detectable s.Ig, as found in the normal state, is not confirmed by examinating various T and B cell proliferative states. Thus surface morphology alone is not sufficient for classifying cells in disease. The precise nature of mononuclear cells from hairy cell leukemia remains nuclear.

Abstract
Similarities between reproductive processes in humans and chimpanzees have led to speculation that the chimpanzee might be an excellent reproductive-endocrine model of humans. Data comparing patterns and concentrations of serum gonadotropins, prolactin, and sex steroids in female humans, chimpanzees, and rhesus monkeys sustain this concept. The striking evidence that levels of estrone, estradiol, estriol, progesterone, and chorionic gonadotropin are similar during human and chimpanzee pregnancy support the contention that chimpanzees, like humans but unlike rhesus monkeys, have a definitive fetoplacental unit. Likewise, during normal menstrual cycles serum patterns of LH, FSH, progesterone, and estradiol are similar in women and chimpanzees, but differ in rhesus monkeys. Thus by using the chimpanzee it may be possible to accurately assess the safety for human use of compounds that might affect reproductive-endocrine processes without direct exposure to humans.

Abstract
A and A1 antigens have been detected on cells of the human erythrocyte series by immunoelectron microscopy. These antigens have been revealed by an indirect method involving various anti-A and anti-A1 antibodies (allo, auto, hetero-antibodies) and peroxidase-conjugated anti-immunoglobulin antibodies. Immunologic labelling has been carried out with erythrocyte or bone marrow cell suspensions which were fixed prior to incubation with reagents. Cells from various A phenotypes were examined. A and A1 antigens were visualized on maturing normoblasts, at every developmental stage. In addition cell to cell variations of the surface labelling of erythrocytes was found in normal phenotypes, suggesting the existence of several populations of cells according to antigenic load.

Abstract
An adenomatoid tumor from the round ligament of a 50-year-old woman was studied by light and electron microscopy. Ultrastructurally the tumor was remarkably similar to normal as well as neoplastic mesothelium, thus lending further support to the concept of a mesothelial origin of adenomatoid tumors. Comparative histochemical and ultrastructural studies revealed presence of acid mucopolysaccharides mainly along the luminal borders of the tumor cells, thus indicating likely production of this material by the tumor cells as opposed to the stromal cells. The stroma was rich in elastic fibers and there was evidence of active elastogenesis. This paper represents the first unequivocal demonstration of elastogenesis in an adenomatoid tumor.

Abstract
Peroxidase conjugated antibodies were applied to cell suspensions in order to detect surface associated immunoglobulins. Cell suspensions were fixed prior to incubation with reagents, a procedure avoiding membrane alterations induced by antibodies to surface component. By immunoelectron microscopy an identification of B lymphocytes could be made with simultaneous observation of their surface architecture. Basic findings were that normal circulating human B lymphocytes had a villous surface. This relationship was not confirmed however by examinating samples from various B and T cell proliferations establishing that surface morphology is not sufficient to categorize cells in disease. Specimens from hairy cell leukemia were also examined. Despite salient surface characteristics as revealed by the present method, the categorization of cells remains unclear.

Spherical protoplast-like structures were released from Neuropsora crassa mycelia under the influence of cell-wall-lytic enzymes obtained from autolyzed cultures of this fungus, in 50 mM borate-citrate-phosphate buffer, pH 5.5 with 0.5-0.8 M mannitol for appropriate osmotic pressure. The protoplasts retain their morphological aspect for several days at 4 C, or for a longer time when they are washed by centrifugation and incubated with 0.8 M mannitol. The free protoplasts are sensitive to osmotic shock and lyse immediately when placed in distilled water; the vacuoles and other cytoplasmatic material remain intact for some time.

Abstract
Immunoelectron microscopy was applied to human lymphocytes exposed to purified peroxidase-conjugated anti-immunoglobulin. Indeed, detectable surface immunoglobulins are a salient feature of so-called " B " lymphocytes. On living cells, a rapid and massive internatization of the labelled membrane is observed. Prior glutaraldehyde cell fixation avoids such a phenomenon. Thus, exposure of fixed cells to conjugated anti-immunoglobulin allows the visualization of a dense and continuous specific membrane labelling. Immunoglobulin-bearing lymphocytes have a characteristic membrane surrounded with numerous microvilli. On the other hand, non-labelled lymphocytes have a smooth membrane. Intermediate forms are also noted among these extreme morphological features.

Abstract
Surface immunoglobulins (sIg) were detected on human lymphocytes by immunoelectron microscopy with peroxidase-conjugated antibodies. Blood, marrow, and thymus cells from normal individuals and patients with lymphoproliferative disorders were examined. Samples were fixed before exposure to specific reagents. Normal lymphocyts with detectable sIg, i.e. B lymphocytes, were characterized by a villous surface; nonlabeled blood lymphocytes and thymocytes were smooth cells. Intermediate cells were also found which in sections appeared moderately villous and labeled, thus identified as B lymphocytes. Further evidence for a relationship between villous surface and sIg was given by the finding of a few lymphocytes with polar concentration of labeled microvilli. In chronic lymphocytic leukemia patients, most cells exhibited a villous surface with parallel variations of the number of microvilli and of anti-immunoglobulin-binding capacity. However, some labeled smooth blastic cells were also observed. On the other hand, abnormal lymphocytes from Sézary's syndrome which could exhibit segments of villous membrane had no detectable sIg. This study confirms that in most cases human B lymphocytes have a characteristic surface appearance and that the detection of sIg in normal lymphocytes correlates with the presence of microvilli.

Abstract
Rosettes obtained by mixing blood mononuclear cells from patients with rheumatoid arthritis and rabbit IgG-coated erythrocytes were examined after micromanipulation. When leucocytes were fractionated by filtration on polyamide fibres, rosettes were all formed by lymphocytes which had an homogeneous morphological appearance. They contained monoribosomes, dense lysosomes and exhibited some degree of membrane activity giving rise to small cytoplasmic projections which firmly bound red cells. On some occasions ingestion of small erythrocyte fragments could be seen. When rosette formation was carried out with cells isolated by centrifugation on Ficoll, a great number of rosette-forming cells appeared to be monocytes. These cells had numerous finger-like projections which deformed and phagocytosed red cells. The detection of monocytes in this system is interpreted as resulting from the presence of surface receptors for IgG molecules. The ultrastructural features of the rosette-forming lymphocytes are discussed with respect to their content in organelles related to protein synthesis and pinocytosis, and also to their membrane activity induced by interaction with IgG-coated erythrocytes.

Abstract
1. As cultures of the fungus Sclerotinia fructigena autolysed, the filtrates contained increasing quantities of a beta-N-acetylglucosaminidase. 2. The enzyme was purified up to 42-fold by a combination of isoelectric focusing and gel filtration. 3. It ran as a single band in cellulose acetate strip electrophoresis and in isoelectric focusing (pI3.76). 4. The enzyme did not readily hydrolyse chitin or a glycopeptide with terminal N-acetylglucosamine residues, but rapidly degraded the N-acetylglucosamine dimer NN'-diacetylchitobiose; the monomer was readily utilized by the fungus as a nitrogen source. The K(m) value for hydrolysis of p-nitrophenyl beta-2-acetamido-2-deoxy-d-glucopyranoside at 37 degrees C was 2.0mm. The Sclerotinia enzyme was generally less susceptible to inhibition by 2-acetamido-2-deoxygluconolactone and other related sugars than the corresponding enzyme from other sources. Inhibition by excess of substrate was observed. 5. The culture filtrate also contained N-acetylgalactosaminidase activity; conflicting evidence was obtained as to whether the same enzyme was responsible for both hexosaminidase activities.
