    Notes: Abstract Summary An injection of a local anesthetics in the paravertebral region produces an analgesic field on the same side of the body, a paravertebral block. One point in question about this block is whether the local anesthetic spreads from the thoracic to the lumbar level of the paravertebral region. The purpose of this study was to find how the anesthetic fluid traveled to the lumbar paravertebral region, if at all. Twelve cadavers were used in this study. 15 ml of crimson dye was injected into the paravertebral region at the 11th thoracic level. The viscerae were removed so that we could examine the dye spread. While the crimson dye spread in the endothoracic fascia posterior to the parietal pleura, it also spread downward in the fascia mostly along the splanchnic nerves. At the upper surface of the diaphragm the dye spread laterally in the fascia, and entered the abdominal cavity through the medial and lateral arcuate ligaments. In the abdominal cavity, the dye was found to have spread so widely in the transversalis fascia that the subcostal, iliohypogastric, ilioinguinal, genitofemoral, lateral femoral cutaneous and femoral nerves were involved. We concluded that the dye in the thoracic paravertebral region can enter the abdominal cavity through the medial and lateral arcuate ligaments. This study explained possible fluid communication between the thoracic and lumbar paravertebral regions and confirmed our former clinical observations. The result is important for the future clinical application of paravertebral anesthesia.

    Notes: Summary Frozen sections of eight primary malignant lymphomas of the brain were examined by the immunohistochemical methods using a panel of monoclonal and heterologous antibodies to B lymphocyte (immunoglobulins, BA-1, Leu-12 and HLA-DR), T lymphocyte (OKT-11 and Leu-1) and monocyte (OKM-1) surface markers. Paraffin sections were also used in the examination of cytoplasmic immunoglobulins. Surface and/or cytoplasmic immunoglobulins (Ig) were observed in seven cases,four of which were shown to be distinctly monoclonal and the other three less so. The remaining 1 case showed no distinct staining for Ig. BA-1, Leu-12 and HLA-DR stainings were positive in four, four and five cases, respectively. The marker phenotypes of (BA-1, Leu-12, HLA-DR) were shown to be (+,+,+) in one lymphoma, (+,-,-) in three, (-,+,+,)in three, and (-,-,+) in one. Thus, it was demonstrated that the present lymphoma cases showed a marked immunological heterogeneity, and it was shown that all of them including the Ig-negative case revealed one or more of these three additional B cell markers, indicating B cell lineage of these cases. Examination of T cell and monocyte markers revealed positive staining in normal or reactive lymphoid cells distributed around blood vessels or sporadically in tumor tissues, but not in lymphoma cells. Epstein-Barr virus (EBV)-associated nuclear antigen was not demonstrated in the seven cases examined, making it unlikely that these lymphomas were related with EBV infection.

    Notes: Summary Frozen cerebral and renal tissue sections of an autopsied “neoplastic angioendotheliosis (NAE)” case were investigated immunohistochemically using monoclonal and heterologous antibodies to lymphocyte, monocyte, endothelial, epithelial and histiocytic antigens. In both tissues, positive stainings for surface immunoglobulin (sIg) μ and ϰ, but not λ, were observed in most of the neoplastic cells. These cells were also positive for other B cell markers (BA-1, Leu-12 and HLA-DR). No distinct staining was observed in the neoplastic cells with antibodies to T lymphocyte (OKT-11 and Leu-1) or monocyte (OKM-1) markers. Posive stainings were observed only in some small round lymphoid cells which were distributed sporadically in and around blood vessels and were considered to be reactive. No positive staining was observed in the neoplastic cells with antibodies to endothelial (factor VIII), epithelial (cytokeratin) or histocytic (lysozyme) antigens. Thus, our NAE case was shown to be of monoclonal B cell lymphoma in nature.

    Notes: Summary Using the Southern blot hybridization technique, four cases of the primary malignant lymphomas of the brain, histologically diffuse large cell lymphoma, were examined for the immunoglobulin gene rearrangements. In three lymphomas, the rearrangements were observed in both heavy and light chain genes, providing strong evidence for a B cell lineage of these tumors. On the other hand, in the remaining lymphoma, the rearrangement was observed only in the heavy chain gene. Despite this, immunohistochemical examination revealed positive stainings for heavy and light chain immunoglobulins in tumor cells, suggesting the occurrence of light chain gene rearrangement at the undetectable level. Thus, B lymphocytic differentiation at the gene level was demonstrated in three, or possibly all, of the primary intracerebral malignant lymphomas examined. Since no more than two rearrangements were detected in each immunoglobulin gene, these lymphomas were considered to be monoclonal in nature.

    Notes: Summary An immunohistochemical study was performed on small lymphoid cells present in frozen tissue sections of seven cases of primary B cell malignant lymphomas of the brain by using monoclonal antibodies to T cell (Leu-1, OKT-11, Leu-3a, and Leu-2a) and B cell (BA-1 and Leu-12) surface markers. In all the seven cases, positive reaction for Leu-1 and OKT-11 was seen in the majority of the small lymphoid cells which were dispersed among the lymphoma cells or clustered around blood vessles. The large neoplastic cells were unstained by these antibodies. Staining for T cell subsets with antibodies to Leu-3a and Leu-2a showed heterogeneous staining in each case. The ratio of Leu-3a+ to Leu-2a+ cells was less than one in six cases, demonstrating a suppressor/cytotoxic phenotype predominance. Most of these small lymphoid cells were negatively stained by antibodies to BA-1 and Leu-12. From these findings, it was shown that the small lymphoid cells observed in primary B cell lymphomas of the brain were of T cell lineage, distinct from the neoplastic cells, and probably reactive in nature. The implications of these findings are discussed.

    Description / Table of Contents: Résumé L'injection d'un anesthésique local dans la région paravertébrales entraîne une analgésie unilatérale localisée (bloc paravertébral). On pouvait se demander si l'anesthésique local diffusait du niveau thoracique au niveau lombaire de la région paravertébrale. Le but de cette étude était de définir comment le liquide anesthésique gagnait la région paravertébrale lombaire, s'il le faisait. 12 cadavres ont été utilisés dans cette étude. 15 mm de colorant rouge ont été injectés dans la région paravertébrale des cadavres au niveau de la 11ème vertèbre thoracique. Les viscères ont ensuite été enlevés pour permettre l'examen de la diffusion du colorant. Le colorant diffusait dans le fascia endothoracique en arrière de la plèvre pariétale, puis vers le bas à l'intérieur du fascia, principalement le long des nerfs splanchniques. A la face supérieure du diaphragme, il diffusait latéralement dans le fascia, et pénétrait dans la cavité abdominale au-dessous des ligaments arqués médial et latéral. Dans la cavité abdominale, le colorant diffusait largement dans le fascia transversalis de telle sorte qu'il atteignait les nerfs subcostal, ilio-hypogastrique, ilio-inguinal, génito-fémoral, cutané latéral de la cuisse, et fémoral. Nous en avons conclu que le colorant pouvait passer de la région paravertébrale thoracique dans la cavité abdominale au-dessous des ligaments arqués médial et latéral. Cette étude montre la communication possible des liquides entre les régions paravertébrales thoracique et lombaire, et corrobore nos observations cliniques préalables. Le résultat en est important pour l'utilisation clinique ultérieure des blocs paravertébraux.

    Notes: Abstract      The highly radioresistant Rubrobacter radiotolerans, contains red pigments. Since the pigments could not be extracted by usual methods, a new method was developed in which the pigments were extracted with organic solvents after addition of 10 N KOH to the intact cells, followed by neutralization. These pigments were also extracted after treatment with achromopeptidase, but not with lysozyme. The extracted pigments separated into two main spots by TLC (48.6% and 22.6%), and were confirmed to be carotenoids by chemical tests. The two major pigments had 13 conjugated double bonds as determined from the main maximum wavelength of the light absorption spectra. Their molecular weights were determined to be 740 and 722 by mass spectrometry. The mass spectra of their TMS-derivatives revealed that they contained four and three tertiary OH groups, respectively. Confirming their identical light and IR spectra, these pigments were determined to be bacterioruberin and monoanhydrobacterioruberin, respectively, the characteristic carotenoids of halophilic bacteria. The existence of these pigments in bacteria other than halobacteria provides interesting new evidence on the distribution of these compounds.

    Notes: Abstract The SRY (sex-determining region Y) gene encodes a transcription factor characterized by a DNA-binding motif termed the HMG (high mobility group) domain. The SOX (Sry-box) genes comprise a large family related by homology to the HMG-box region. We isolated a cDNA clone with an open reading frame encoding a putative protein of 384 amino acids, which shared 83% identity to the mouse Sox18 protein. Northern blot analysis revealed that a 1.9-kb band of human SOX18 messenger RNAs was predominantly expressed in heart, although weak signals were seen in brain, liver, testis, and leukocyte. By polymerase chain reaction (PCR)-based analyses with both a human/rodent monochromosomal hybrid cell panel and a radiation hybrid panel, the gene was mapped to the chromosome 20q13.33 region.

    Notes: Abstract Members of the RAB protein family are important regulators of vesicular fusion and trafficking. A putative new member of the RAB family of genes was identified through a public database search, and its full-length cDNA was isolated from a human fetal brain cDNA library. The predicted protein product of the gene consists of 190 amino acid residues and has 87% identity with rat Rab26. Thus, we designated this gene as the human RAB26-related gene. Reverse transcription-coupled polymerase chain reaction (RT-PCR) demonstrated that the RAB26-related messenger RNA was predominantly expressed in adult and fetal brain. Furthermore, an RT-PCR experiment for brain subregions showed that the mRNA was highly expressed in the amygdala, cerebellum, caudate nucleus, and hippocampus. By PCR-based analysis with both a human/rodent monochromosomal hybrid cell panel and a radiation hybrid panel, the gene was mapped to the chromosome 16p13.3 region between markers WI-7742 and WI-3061. The RAB26-related gene consists of eight exons that span about 44 kb of the genome DNA.
