The rostrocaudal organization of motoneurones of the cat's m.peroneus longus (PerL) was investigated with respect to motoneuronal size (soma diameter) as well as muscle unit contractile properties (twitch speed,
fatigue
resistance, maximum force). Sizes of cell bodies were measured after retrograde labelling with horseradish
peroxidase
. Other properties were studied by aid of electrical stimulation of rostro-caudally distinct subfilaments of ventral roots. A weak but significant tendency was found for units to become somewhat slower and more
fatigue
-resistant at caudal than at more rostral levels within the pool. Neurones of different sizes and unit properties were, however, very widely intermingled at all levels of the pool. Rostro-caudally distinct root filaments gave rise to differentially located electromyographic signals in the muscle. The experimental results led to the following main conclusions: a type-specific intraspinal innervation of PerL motoneurones is unlikely to be arranged predominantly on topographical principles; and the intraspinal site of PerL motoneurones is related to the intramuscular site of their muscle fibres.

There have been few reports of acute leukemia presenting with a hypocellular bone marrow. All patients diagnosed as having acute leukemia were identified during a recent six-year interval who had blast cells plus promyelocytes of greater than 30% and marrow cellularity of needle biopsy less than or equal to 50%. Of 195 patients analyzed, 15 (7.7%) fulfilled the criteria. Ten patients were men and five women; the median age was 68 years with a range of 40-82. Seven complained of
fatigue
of 6-12 months duration, five were seen with occult infection, and three were asymptomatic. Hepatosplenomegaly was absent in 93% and none had lymphadenopathy. Fourteen patients were pancytopenic with median leukocyte count at presentation of 1.5 X 10(9)/liter, hemoglobin of 9.0 g/dl, and platelet count of 55 X 10(9)/liter. Circulating blast cells were not observed in ten patients; in the other five they were less than 0.7 X 10(9)/liter. The morphology of all cases appeared myeloid and Auer rods were seen in three patients; however, in one the
peroxidase
was negative. Classification according to FAB criteria revealed ten to be M1, three to be M2, one M4, and one L2. Median survival of the entire group was seven months. Of seven patients receiving no chemotherapy, two survived longer than 1 year (14, 24.5 months), one is alive at 7+ months, and the median survival was seven months. Eight patients with life-threatening complications received various combination regimens including an anthracycline, cytosine arabinoside, 6-thioguanine, vincristine, and prednisone. Five died of treatment complications; two achieved durable complete remission and are free of disease at 17 and 27 months. It can be concluded that hypoplastic acute leukemia is a distinct nosologic entity affecting primarily older patients with myeloid leukemia. Remission induction therapy in patients who are seriously ill has a low success rate, and in some patients prolonged survival is possible with supportive care alone.

The specialized jumping muscle of the locust, the metathoracic extensor tibiae (ETi), is innervated by four physiologically different motoneurons, including FETi, a phasic excitor, SETi, a tonic excitor, and CI, a tonic common inhibitor. FETi neuromuscular junctions were examined in three phasic ETi bundles innervated by FETi. FETi terminals were characterized by patchy contacts on to granular sarcoplasm. The ETi accessory extensor, innervated by both SETi and CI, contains two morphologically different types of axon ending. When this muscle was soaked in horseradish
peroxidase
, stimulation of SETi led to selective uptake in vesicles in terminals similar to those of FETi axons but containing smaller vesicles, while stimulation by CI caused increased uptake into terminals with more extensive contact directly on to fibrillar sarcoplasm. As has been observed in excitatory and inhibitory synapses in some crustacean and vertebrate nervous systems, the synaptic vesicles in the locust excitatory endings are round and electron-lucent while those in the inhibitory endings are more irregular in shape. The tonic neuromuscular junctions, SETi and CI, are more densely packed with vesicles, larger in cross-sectional area and appear to be of more complex shape than the smaller, vesicle-sparse, phasic FETi terminals. Following long duration stimulation at 10 Hz, the tonic neuromuscular junctions showed little morphological change. FETi endings, which
fatigue
within minutes at the same stimulation frequency, showed a 20% decrease in synaptic vesicle density and an increase in irregularly shaped membrane inclusions.

A 53 year old man first presented with a mild anti-neutrophil cytoplasmic antibody (ANCA), type (
MPO
-ANCA) associated microscopic polyangiitis. Approximately one year later, he presented with
fatigue
, fever, cough, sore muscles and erythrocyturia. At admission he was uraemic. Kidney biopsy showed in LM extracapillary glomerulonephritis and in immunofluorescence microscopy linear deposition of IgG along the glomerular basement membrane (GBM).
MPO
-ANCA was still positive, but antibodies against GBM were now also present. Retrospective analysis revealed the presence of anti-GBM antibodies nine months before clinical illness. Pr3-ANCA (C-ANCA) was negative during the whole course. In spite of decreasing anti-GBM antibody levels during treatment, his condition aggravated, and he died from complications. Thus, coexisting anti-GBM antibodies may explain suddenly deteriorating renal function in patients with ANCA associated vasculitis.

Diverse immunologic abnormalities have been described in women who received silicone breast implants. However, most studies have focused on either a limited number of patients or a small panel of autoantibodies. We report the analysis of 20 autoantibodies in 116 women with implants and 134 controls. The patients ranged from 26- to 66-years-old, with a mean of 45.7 +/- 8.3 years; breast prostheses were in place for a mean of 15 +/- 5.6 years, with a range of 4 to 30, the chief complaints of the 116 patients included polyarthralgias,
fatigue
, myalgias, morning stiffness, and decreased memory. All 250 sera were tested blindly using a panel of 20 autoantigens including SS-A, SS-B, RNP, cardiolipin (CL), collagen types I, II and IV, phosphatidylserine (PS),
myeloperoxidase
(
MPO
), sulfatides (sulf), thyroglobulin (TG), gangliosides (GDIa;GM2), proteinase-3 (PR3), Jo-1, Sm, HPRPP-ribosomal phosphate, histones (H2AH2B), Scl-70 and glomerular basement membrane (NC-1). Values from individual patients were considered positive only when greater than 3 SD above the control mean. There was a statistically significant greater frequency of autoantibodies in women with implants for 15 of the 20 autoantigens; these were particularly striking for anti-H2AH2B, HPRPP, SS-A, SS-B, Scl-70, CL, PS, GM2, and NC-1. Many patients harbored several autoantibodies; 20% had four autoantibodies; 8% had six autoantibodies. The association of autoantibodies and implants suggests an adjuvant action of silicon/silicone byproducts.

A 30-year-old female was admitted to our hospital complaining of high fever and
fatigue
. Laboratory findings showed as follows; WBC 41,500/microliter (40% of blasts), Hb 8.5g/dl, platelets 4.4 x 10(4)/microliter. Cytochemical staining of blasts was positive for
peroxidase
and non-specific esterase with NaF inhibition. Chromosome analysis showed 46, XX, inv (16p+,q-). AML with eosinophilia was diagnosed. During myelosuppression after remission induction therapy, she developed high fever, and did not respond to transfusions. Marrow smears showed the presence of phagocytic histiocytes consisting of 18% total nuclear cells. A diagnosis of reactive histiocytosis (RH) was made. She recovered spontaneously, but suffered two episode of recurrence during subsequent chemotherapy. Reactive histiocytosis is characterized by proliferation of histiocytes which phagocyte blood cells in immunodeficient cases, e.g. a myelosuppressive state after chemotherapy. RH causes high fever and prolonged myelosuppression. It is considered to be one of the poor prognostic factors in AML during chemotherapy, and spontaneous recovery is rare. In this report, the effect of hydrocortisone on histiocytes derived from patient marrow was also investigated in vitro.

In December 1993, a 76-year-old Japanese male presented with general
fatigue
. Peripheral blood (PB) examination indicated marked leukocytosis (WBC count, 19.8 x 10(4)/microliter; leukemic blast differential, 89.5%). Leukemic blasts were positive for CD33, and negative for lymphoid antigens, with 2% of the blasts being positive for
myeloperoxidase
staining. On admission, chromosome analysis of leukemic cells in PB showed 45, X,-Y, t (9;22) [12/15]/46, XY, t (9;22) [3/15]. Southern blot analysis of the DNA from PB showed a rearrangement at the M-BCR region and germline configurations of both TCR beta and IgH chain genes. The patient was diagnosed as Philadelphia-positive chronic myelogenous leukemia (CML) in blast crisis. We commenced treatment with daunorubicin (DNR; 20 mg/day x 1 IV) and daily prednisolone (PSL; 60 mg/day PO). Leukemic blasts disappeared rapidly from PB, while the promyelocytes showed a transient increase, peaked 7 days after the start of therapy, and then disappeared. Myelocytes and metamyelocytes also showed transient increases. Without a period of severe myelosuppression, the patient reverted to the chronic phase of CML and karyotypic analysis of bone marrow cells showed 45, X,-Y, t (9;22) [33/35]/46, XY, [2/35]. Consolidation chemotherapy with DNR and BHAC was started, but the patient's condition deteriorated due to bacterial infection and he died of hepatic failure on March 1994. In this case, reversion to the chronic phase of CML in blast crisis may be accomplished by the cytodifferentiating effects of small-dose DNR and oral PSL to the leukemic blasts.

A 67-year-old female was admitted with
fatigue
. Peripheral blood examination showed severe pancytopenia. Bone marrow biopsy revealed hypoplastic marrow. She was diagnosed as having aplastic anemia. Steroid pulse therapy was not effective. After treatment with erythropoietin (EPO) and granulocyte colony-stimulating factor (G-CSF), blasts which were positive for CD13, CD33, CD34 and HLA-DR and negative for
myeloperoxidase
appeared in the peripheral blood. At this time, bone marrow biopsy revealed myelofibrosis with increased blasts. Chromosome analysis showed 46XX, add (1) (p36), add (1) (q44), -2, -5, del (7) (q11), -12, +3mar. She died of pneumonia despite chemotherapy with etoposide. Administration of EPO and G-CSF may have led to the rapid development of leukemia and myelofibrosis.

A 60-year-old Japanese woman was admitted to our hospital because of
fatigue
, weight loss and abdominal distension. Myelofibrosis was diagnosed, based on anemia, huge hepatosplenomegaly, leukoerythroblastosis and bone marrow fibrosis. Following treatment with ranimustine, anemia and splenomegaly improved. Seven months after initial therapy of ranimustine, however, polycythemia (RBC 7.39 x 10(6)/microliter; Hb 19.1 g/dl, Ht 65.9%) developed gradually, then RBC decreased to normal level following venesection (total 1,200 ml). After 32 months, blastic transformation occurred. The blasts were negative for
myeloperoxidase
. By flow cytometric analysis, the cells were positive for CD2, CD13, CD33 and HLA DR. Thus, AML (M0) was diagnosed. Despite of treatment with multicytotoxic agents, she died of DIC 36 months after the initial diagnosis of myelofibrosis. The progression from myelofibrosis to polycythemia is rare and only 15 cases have been reported so far. In addition, although a chromosomal abnormality, 46, XX, t(3; 12) (q25; p11), was present at the time of first diagnosis of myelofibrosis, the development of an additional abnormality, del(11) (q-), might be related to the transformation to AML.

Recently group A Streptococcus toxic shock like syndrome (TSLS) has been reported, but as for group B streptococcus (S. agalactiae) infection, there have been little documentation in the literature. We report a case of fluminant septic shock due to Streptococcus agalactiae (S. agalactiae). A 72-year-old male was admitted to our hospital because of general
fatigue
and azotemia. He was diagnosed as having
MPO
-ANCA related glomerulonephritis and treated with steroid therapy. Gradually he was doing well. On the 228th hospital day, he suddenly had tachypnea, transient conscious disturbance, and profound hypotension. About 16 hours later, he died despite intensive treatment. S. agalactiae was isolated from the blood. Autopsy revealed bilateral bronchopneumonia and shock liver. To our knowledge, this is the first report of septic shock caused by S. agalactiae.
