    Notes: Room temperature continuous wave operation of ZnSe-based blue/green laser diodes grown homoepitaxially on conductive ZnSe substrates with threshold current densities as low as 176 A/cm2 has been demonstrated. This is the lowest reported threshold among all short wavelength lasers in the blue/green region. Lifetimes at room temperature of up to 2.1 h have been obtained for lasers with pre-existing defect densities lower than 3×104 cm−2. © 1998 American Institute of Physics.

    Description / Table of Contents: Résumé La perfusion continue hyperthermique (CHPP) avec une solution contenant 30 mg de mytomycine C (MMC) et 300 mg de cisplatine (CDDP) a été utilisée comme traitement prophylactique pour prévenir la récidive péritonéale chez 79 patients avec un cancer gastrique avancé réséqué. Un groupe composé de 81 patients avec un cancer gastrique avancé qui ont eu une chirurgie à visée curatrice pendant la même période de temps a servi de contrôle. La CHPP, perfusion de MMC et de CDDP mélangés au sérum physiologique réchauffé à 43.5°C par un appareil spécial, était administrée pendant 60 minutes. Lorsque l'envahissement séreux a été confirmé par l'examen anatomopathologique, la survie des patients ayant eu la CHHP était significativement plus longue que lorsque les patients n'avaient pas eu de CHHP. La survie des patients classés stade IV était également améliorée. Il n'y avait aucune amélioration, par contre, de la survie lorsque la couche séreuse n'était pas envahie. Des effets secondaires ont été observés chez quatre patients qui ont une CHHP: un a développé une aplasie médullaire sévère, alors que les trois autres n'ont eu qu'une hyperazotémie transitoire. Il n'y avait, en définitive, aucune différence de mortalité ou de morbidité entre les deux groupes. Ces résultats indiquent que la CHPP est sûre et facilement disponible comme thérapie prophylactique contre la récidive péritonéale après résection de cancer gastrique.
    Abstract: Resumen La perfusión hipertérmica peritoneal continua (CHPP) con una solución que contiene 30 mg de mitomicina C y 300 mg de cisplatino ha sido introducida como tratamiento profiláctico para prevenir recurrencia peritoneal luego de la resección curativa en 79 pacientes con cáncer gástrico avanzado. El grupo control consistió en 81 pacientes con cáncer gástrico avanzado que fueron sometidos a cirugía curativa en el mismo período de tiempo. La CHPP fue realizada durante 60 minutos con solución salina con MMC y CDDP calentada a 43.5°C por medio de un sistema de CHPP. En los pacientes con invasión serosa confirmada histológicamente, la tasa de sobrevida del grupo CHPP fue significativamente mayor que la del grupo control. También se detectó una ventaja de sobrevida en los pacientes en estado IV tratados con CHPP. Sin embargo, no se encontró ventaja en cuanto a sobrevida entre el grupo CHPP y el grupo control en los pacientes con tumores negativos para invasión serosa. Efectos adversos fueron registrados en 4 pacientes con CHPP:1 desarrolló severa depresión de la médula ósea, e hiperazotemia transitoria fue observada en los otros 3 pacientes. Sin embargo, no se halló diferencia en cuanto a mortalidad y morbilidad entre los dos grupos. Estos resultados indican que la CHPP es una modalidad terapéutica segura y fácilmente disponible para prevenir la recurrencia peritoneal luego de cirugía por cáncer.
    Notes: Abstract Continuous hyperthermic peritoneal perfusion (CHPP) with a solution which contains 30 mg mitomycin C and 300 mg cisplatin has been introduced as a prophylactic treatment for peritoneal recurrence after curative resection of 79 advanced gastric cancers. The control group consisted of 81 patients with advanced gastric cancer who underwent curative surgery during the same period. CHPP was performed for 60 minutes by perfusing MMC- and CDDP-containing saline solutions warmed at 43.5°C by a special CHPP device. In patients with pathologically confirmed serosal invasion-positive tumors, the survival rate of the CHPP group was significantly higher than that of the control group. A survival advantage for stage IV patients was also obtained by CHPP. However, there was no survival advantage between the CHPP group and the control group with serosal invasion-negative tumors. Adverse effects were observed in four patients who underwent CHPP: One developed severe bone marrow suppression, and transient hyperazotemia was ebserved in the other three. There was no difference in the incidence of mortality and morbidity between the two groups. These results indicate that CHPP is a safe, readily available prophylactic therapy for peritoneal recurrence after gastric cancer surgery.

    Notes: Abstract. An 11-month-old girl with congenital heart disease developed infective endocarditis. Blood cultures revealed an unusual gram-negative rod, Rahnella aquatilis. The patient was successfully treated with a combination of netilmicin and ceftazidime. This is the first case report of infective endocarditis caused by this organism. R. aquatilis should be recognized as a clinical pathogen capable of causing life-threatening infection in children and adults.

    Notes: Abstract Effects of E-5110, a novel non-steroidal antiinflammatory drug, on interleukin-1 (IL-1) generation from human monocytes were studiedin vitro. E-5110 reduced the amounts of extra- and intracellular IL-1 activity induced by lipopolysaccharide (LPS, 1 μg/ml) in a dose-dependent manner (1–10μM). E-5110 also inhibited the IL-1 generation induced by antigen-antibody complexes, opsonized zymosan and silica particles. It was suggested that the inhibition of IL-1 generation by E-5110 was independent of the inhibitory effects on arachidonate cyclooxygenase and/or lipoxygenase because indomethacin, piroxicam, BW755C and AA861 had no effects on IL-1 generation. Hydrocortisone (IC50:0.084 μM), aurothioglucose (11.5 μM) and lobenzarit (75.0 μM), which are clinically effective antirheumatic drugs, also inhibited IL-1 generation, like E-5110 (1.21 μM). It is expected that E-5110 will be superior to classical non-steroidal antiinflammatory drugs in medical treatment of rheumatoid arthritis.

    Notes: Abstract Thein vivo production of lymphocyte activating factor (LAF) activity was investigated in the exudate of the rat air-pouch inflammation model. An inflammatory reaction was induced by lipopolysaccharide (LPS) injection into the air-pouch, and the time course of LAF activity in the exudate was investigated. LAF activity in the exudate reached a peak by 6 h, and rapidly decreased at 10 to 48 h after the LPS injection. Dexamethasone revealed strong inhibitory action on LAF activity and granuloma formation. On the other hand, indomethacin could not inhibit either of the phenomena. In conclusion, LAF (IL-1) is rapidly produced after the onset of inflammation and may participate in the subsequent granuloma formation.

    Notes: Abstract The antiinflammatory activity of a novel pyrrolidone derivative E-5110 was investigated using anti-inflammatory, analgesic and antipyretic animal models in comparison to indomethacin (IND) and piroxicam (PIR). The acute antiinflammatory activity of E-5110 on carrageenin paw edema was similar to IND, and half of PIR. E-5110 inhibited the pleural exudate volume and leucocyte infiltration in a reversed passive Arthus reaction more potent than IND. The chronic inflammatory responses in the established adjuvant- and type II collagen-induced arthritis were suppressed by E-5110 similar to IND and PIR. The analgesic potency of E-5110 was similar to IND and PIR, but the antipyretic activity of E-5110 was more potent than that of IND, and slightly more potent than that of PIR. The ulcerogenic effect of E-5110 on rat gastric mucosa was less than that of the reference drugs.

    Notes: Abstract Cultured rat synovial cells generate PGE2 upon stimulation with a factor derived from rate polymorphonuclear cells (Prostaglandins27, 697, 1984). E-5110 inhibited PGE2 generation by the synovial cells. The IC50 values (μM) for inhibition of PGE2 generation were 0.026 for E-5110, 0.008 for indomethacin, 0.112 for piroxicam, 0.003 for R-830, 0.667 for BW-755C and 2.05 for benoxaprofen. Calcium ionophore A-23187-stimulated LTB4 generation by human neutrophils was inhibited by E-5110 with an IC50 value of 0.20 μM, which was similar to NDGA. The inhibition of LTB4 by E-5110 was more potent than that of R-830, BW-755C or benoxaprofen. E-5110 also inhibited superoxide generation by human neutrophils stimulated with opsonized zymosan, f-Met-Leu-Phe and phorbol myristate acetate. These results indicate that E-5110 is a potent dual inhibitor that suppresses superoxide generation.

    Notes: Summary The aim of the study was to determine the destination of the α1-antitrypsin-elastase complex, which is found in circulating blood after the peroral administration of elastase. The complex was made in vitro by mixing hog pancreatic elastase with human α1-antitrypsin and then injected intravenously into rats and mice. Tissues taken at various times after injection were subjected to histochemical staining using an antibody against elastase. Light micro-scope observations revealed dense deposition of reaction products in the elastic lamina of the arterioles; moderate or slight deposits were seen in the tissues surrounding arteries, in the tubular epithelial cells of the proximal convoluted tubules in the kidney, and in the pancreatic ducts.Immuno-electron microscopy revealed heavy deposition of the reaction product in the elastic lamina of the small arteries and arterioles; some dissolution of the elastic fibers was also evident. Pinocytic uptake of the α1-antitrypsin-elastase complex was observed on the abluminal surface of endothelial cells and in smooth-muscle cells bordering the elastic lamina of arterioles. The endothelial cells of the arteries and arterioles retained their normal morphological appearance, although local desquamation was observed in some animals. The results indicate that, when the α1-antitrypsin-elastase complex is present in the circulating blood, it is incorporated into the elastic lamina through the endothelial layer. This results in liquefaction of the lamina, desquamation of endothelial cells and leakage of the complex into the perivascular tissues via the vascular walls. However, some of the complex seems to be excreted very quickly from the kidneys.

    Notes: Summary In order to reveal the absorption process of elastase from the intestine, hog pancreatic elastase was injected into the ligated jejunum lumen of the rat, and the tissues were cytochemically observed at various times after injection. The peroxidase anti-peroxidase (PAP) method using anti-hog-elastase rabbit antibody was used for light microscopy, and the anti-elastase Fab′-peroxidase conjugate was used for electron microscopy. The tissues stained by the PAP method exhibited a dense deposition of reaction products on the luminal surface of epithelial cells and a moderate deposition in the blood and lymph capillaries of the intestinal villi. Immunoelectron microscopy revealed that the reaction product was deposited on the surface of the microvilli and in their pocketing; some was found in the pinocytotic vesicles in the terminal-web area and on the inner surface of the enlarged smooth endoplasmic reticulum. Round droplets which gave a positive reaction were found in the widened intercellular cleft and the thick basement membrane lining the blood capillaries and lymphatics. The jejunum retained its normal ultrastructure. The results indicate that the elastase molecules, which were introduced into the rat jejunum lumen, were absorbed without being decomposed through healthy intestinal epithelial cells by pinocytosis and translocated into blood and lymph capillaries.
