    Notes: Abstract. Objective: The purpose of this study was to analyze the biochemical characteristics of synovial fluids after treatment of patients with rheumatoid arthritis (RA) with intra-articularly injected hyaluronate (HA).¶Treatment: In a double-blind study, 13 patients received intra-articular injections of 1% HA in phosphate buffered saline (PBS) while 13 other patients were injected 0.01% HA in PBS, as the control group. Injections were administered once a week for five weeks.¶Methods: Clinical efficacy and characteristics of synovial fluid were compared between groups.¶Results: Significant clinical improvement was observed in the HA-treated group compared to the control group. The viscosity of retained synovial fluid increased. Stringing and HA concentration increased significantly whereas the concentrations of protein and chondroitin sulfate 4 and 6 decreased significantly. The HA molecular weight remained the same in both groups.¶Conclusion: Intra-articular HA injection altered the properties of synovial fluid and proved efficacious for patients with RA.

    Notes: Abstract Bucillamine [SA96: N-(2-mercapto-2-methylpropanoyl)-l-cysteine], a synthetic SH compound, has recently been developed as remission-inducing agent for rheumatoid arthritis (RA), and its clinical usefulness for RA has been proved in Japan. Bucillamine suppressed the mitogen-induced proliferation of murine lymphocytesin vitro. The present study was undertaken to clarify the effect of bucillamine primarily on the release of interleukin (IL)-1 from monocytes and on the proliferation of T cells. Bucillamine significantly inhibited IL-1-induced thymocyte proliferation in a dose-dependent manner. And, bucillamine also inhibited IL-2-induced proliferation at the concentration of 1×10−4 M, but augmented proliferation at the concentration of 1×10−5 M. In contrast,d-penicillamine (an analogous SH compound to bucillamine) did not show any significant effect at similar concentrations.

    Notes: Abstract A 71-year-old male suffering from an intraductal papillary tumor of the pancreas was admitted to our hospital for further investigation. Diagnostic trials, including endoscopic retrograde pancreatography, did not produce an adequate ductography because of a large amount of mucinous fluid. Therefore, we performed endoscopic ultrasonographic-guided punctured pancreatic ductography (EPPD). This procedure was safely performed without any complications. We report this initial and successful trial of EPPD.

    Notes: Abstract Adaptation of solitary corals, Fungia repanda and F. echinata, and their zooxanthellae to low light and ultraviolet light B (UV-B) was studied with respect to changes in their protein contents, photosynthetic pigment contents and the photosynthesis-irradiance (P-I) curves. The corals were collected from 1 to 50 m depths in the Republic of Belau (Paulau) in 1990 and 1991. The chlorophyll a content in a unit surface area of the coral did not change significantly with the depth of the habitat, whereas cellular chlorophyll a in the algae increased with the depth. Zooxanthellae density and protein content in a unit surface area of Fungia spp. decreased with the depth. Photosynthetic parameters normalized by a unit surface area of the Fungia spp., maximum gross photosynthetic rate (P gmax area-1) and dark respiration rate (R area-1), were negatively correlated with the depth, while initial slope of the P-I curve (α) did not show significant correlation with the depth. Compensation light intensity (Ic) decreased with the depth. In isolated zooxanthellae, P max chl a -1, and R chl a -1 decreased with the depth, while αchl a was constant. P gmax cell-1 and R cell-1 did not change significantly but αcell increased with the depth. Ic decreased with the depth as in the intact corals. Reduction of protein content in a unit area of the coral from deeper habitat implies decrease of host animal tissues. Reduction of Ic can be explained by decrease of R area-1, which may be due to the diminution of animal tissues. The photoadaptational response to low light intensity of intact Fungia spp. was found to be a combination of the photoadaptation of symbiotic algae and the decrease of host animal tissue. In order to study their adaptation to ultraviolet (UV) radiation, P-I curves of Fungia spp. and isolated zooxanthellae were analyzed before and after UV-B irradiation. 1 h UV-B irradiation showed no effect on the photosynthetic rate of the shallow water (1 m) corals, while it inhibited the photosynthesis of the deep water (30 m) corals and zooxanthellae isolated from both shallow and deep water corals. These results indicate that the host, Fungia spp., in shallow water have protective mechanism for intense UV-B in their habitat. These photoadaptational mechanisms seem to allow the Fungia spp. to have wide vertical distribution where light intensity spans more than two orders of magnitude.

    Notes: Abstract. Organic molecules adhered to the point of a micropipette were transferred onto the surface of a polymer film by pulsed laser light guided through a quartz optical fiber which was inserted into the micropipette. Controlled by a high-resolution piezoelectric driver designed for scanning probe microscopy, the distance between the micropipette point and the polymer surface was kept to a few tens of nm. After laser irradiation, the deposited molecules on the polymer surface were examined with optical transmission, fluorescence, atomic force, and scanning near-field optical microscopy. It was demonstrated that various kinds of organic molecules can be implanted into sub-micrometer regions at the surfaces of polymer films without their decomposition. The hypothetical mechanism of the molecular transfer is discussed in relation to the morphology of crystalline molecules adhered at the micropipette apertures.

    Notes: Summary The plasma (or serum) protein binding of disopyramide (DSP) in five haemodialysis patients was studied using an ultrafiltration technique. There was an increase in the free fraction of DSP in the plasma on dialysis days in comparison to the levels on interdialysis days, which was associated with an elevation of the free fatty acid levels in the plasma together with the increase of the free fraction of DSP. The inhibitory effect of free fatty acids on DSP binding in an in vitro study was enhanced in proportion to their concentrations, and was shown to be due to competition at one binding site by experiments with oleic acid as a representative displacer. Certain endogenous organic acids, such as indoxyl sulphate, 2-hydroxyhippuric acid and hippuric acid, which are characteristically elevated in chronic renal failure, scarcely affected the protein binding of DSP. The findings indicate that free DSP should be monitored in patients with elevated plasma free fatty acid levels, such as those on haemodialysis therapy.
