The first case of Pseudallescheria boydii meningjitis in China — Electron microscopic study and antigenicity analysis of the agent

Summary Reported in this paper is the first case of isolation ofPseudalle-Scheria boydii from cerebral spinal fluid of a boy with meningitis in China. Morphology and culture were observed by light microscopy, electron scanning microscopy and transmission electron microscopy. In addition, mycelium antigen prepared by SDS-PAGE was compared with that of the other strain of Scedosporium apiospermum. Both of the strains showed more than 40 peptide lines. Their molecular weight was very similar. On the CS-930 Dual-Wavelength TLC Scanner the peaks of both antigens showed to lie in nearly the same position. It could be concluded thatPseudallescheria boydii andScedosporium apiospermum belong to the same genus, but they are of different strains and reproductive phases.

小剂量生长抑素激动剂SMS201—995对正常成人胆囊收缩...

Recently, a long-acting, somatostatin analogue, SMS201-995(SMS), has been developed and extensively investigated. It has been proved to be remarkably effective in treating many diseases, including active acromegaly. We observed the effect of SMS on gallbladder contractility in normal adults using the fatty meal test. Our results show that gallbladder contractility was inhibited significantly for 6 hours after the subcutaneous injection of SMS in dosages of 50, 25, 12.5, and 5 micrograms. We conclude that it is not practical to avoid gallbladder disfunction during long-term SMS treatment by decreasing the dosages of SMS.     

The effect of bile duct ligation and bile diversion on FK506 pharmacokinetics in dogs.

Mongrel or beagle dogs were submitted to bile duct ligation, or to extraenteric biliary diversion by means of choledochoureterostomy. The kinetics of intravenously administered FK506 was not changed from control status two weeks after bile duct ligation, but the bioavailability of orally administered FK506 was nearly quadrupled. Following oral administration, the absorption of FK506 was highly variable. The results indicate that in dogs FK506 is absorbed from the intestine just as efficiently in the absence of enteric bile and in presence of exogenous bile salt supplement when compared with its absorption in presence of normal bile drainage. These findings with FK506 are different from those with cyclosporine after biliary obstruction or diversion and will have important practical as well as experimental ramifications.     

Association and linkage with quantitative traits

This paper examines two approaches for the analysis of quantitative traits: (1) association studies and (2) linkage studies. The trait studied was Q1 from simulated Problem 2 data set in Genetic Analysis Workshop 9. Our purpose was to evaluate associations present in the data, to identify nongenetic and genetic predictors of the trait, and to explore the simulated genome for linkage. Through the association study, we found evidence for the primary major gene associated with this trait. The linkage study found evidence of residual genetic effect acting through other traits. Adjustments of Q1 for Q2 and Q3 led to a failure to find significant effects of MG2 and MG3. This supports the suggestion that adjustment for genetically influenced traits for effects of other genetic traits can reduce the power to detect major gene effects. In summary, we detected the major gene directly associated with the trait of interest through association studies. Linkage analysis detected evidence for two other genes associated to a lesser degree with the trait. © 1995 Wiley-Liss, Inc.     

护生自身练习护理操作的伦理问题及对策

自身练习护理操作就是以护生作为练习对象,相互间在各自身上完成注射、输液等操作练习项目,以达到教学要求[1]。在基础护理的教学中,自身练习对于调动护生的参与感,增加真实感,满足成就感方面起着十分重要的作用。但是,也必须看到在积极效果背后的种种矛盾以及由这些矛盾可能导     

Macrophages are activated by 17beta-estradiol: possible permission role in endometriosis.

On the basis of the common occurrence of high concentration of estrogen and activated macrophages in patients with endometriosis, we postulate that interaction between 17beta-estradiol and macrophage may be an important affair in endometriosis. So our study was focused on the effect of 17beta-estradiol on macrophage. First morphology of macrophages was examined with environmental scanning electron microscopy. Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17beta-estradiol treated macrophages. Then Nitrate and nitrite level in the supernatant was measured by the method of Griess and iNOS expression was analyzed using immunohistochemical staining. It showed that 17beta-estradiol could induce NO release from peritoneal macrophages and expression of iNOS was increased. Also more TNF-alpha in supernatant that was measured by MTT via L929 cell was produced by macrophages under the inducing of 17beta-estradiol. Furthermore, [Ca2+]i, which was viewed by microscope in a laser scanning confocal unit, elevated 39.8% in peritoneal macrophages after 17beta-estradiol 100 nmol/L treated. The results above demonstrated that peritoneal macrophage had been activated in both morphology and cytokine line when interaction with 17beta-estradiol, which indicated that macrophage activated by 17beta-estradiol might play a permission role in development of endometriosis.
