2.SLIDE MAKING METHODS FOR PREDACIOUS NEMATODE FUNGI
Microbiology 1992;0(01):-
Some problems were settled in making permanent slide for predacious nematode fungi by slide cultivation and cotton blue stain. Method of small-hole culture covered with slides could obtain high quality images, which solved the problem that trapping device couldn't be observed with high-power microscopes and oil-immersion microscopes. Scraping slide technique improved the method of making temporary slides.

Objective To observe the preliminary clinical results and safety of 27-gauge microincision vitrectomy surgery for partial vitreoretinal diseases.Methods A total of 13 patients (13 eyes) who underwent 27-gauge microincision vitrectomy surgery were enrolled.The follow-up period was 6 to 12 months.Preoperative and postoperative visual acuity and intraocular,total operative time,cutting time for removing vitreous,wound healing status,intraoperative and postoperative complications were observed.Results Mean best corrected visual acuity improved from preoperative (1.26±0.66) logMAR (0.10±0.09) to postoperative (0.63±0.52) logMAR (0.35±0.24),and the difference was statistically significant (t=2.743,P=0.018).The difference of mean preoperative intraocular pressure (IOP),IOP of postoperative day 1,day 5,one month and final postoperative visit were not statistically significant (F=0.593,P>0.05).The mean total operative and cutting times were (36.38±14.97) min and (10.12±3.54) min respectively.Postoperative scleral incision showed linear closure,no cases of postoperative sclerotomyrelated complications such as wound dehiscence,vitreous incarceration and subcoujunctival fluid were observed.No intraoperative and postoperative complications of iatrogenic retinal breaks,endophthalmitis,choroidal detachment,retinal detachment and vitrous hemorrhage were observed.Conclusions The 27-gauge microincision vitrectomy surgery can improve postoperative visual acuity for treatment of vitreoretinal diseases and induce fewer sclerotomyrelated complications,which maybe a safer surgical approach.

Objective To evaluate the changes of cardiac function and myocardial perfusion by Gated 99Tcm-MIBI myocardial perfusion imaging after autologous mesenchymal stem cell implantation in patients with acute myocardial infarction at high altitude area.Methods 33 patients with anteroseptal myocardial infarction were ran- domly divided into two groups.18 patients (control group) underwent percutaneous tranluminal coronary angioplasty (PTCA) and 14 cases (transplantation group) received additional mesenchymal stem cell transplantation.Myocardi- al perfusion imaging were performed in all patients before and at 6 and 12 months after treatment.Results Com- pared to pre-implantation,LVEF of transplantation group was improved 8%~9%after 6 months.The improving lev- els of control group were lower.However,there were not statistical differences among all data.Conclusion Mesen- chymal stem cell transplantation could improve myocardial systolic function and myocardial perfusion.

Objective To assess ventricular function of early stage neonates of different gestational ages by tissue doppler imaging(TDI).Methods Pulsed wave TDI velocities were obtained in 36 cases of premature infants with gestational ages of 32 to 36 weeks(premature group) and 33 cases of full-term infants(full-term group) aged 3 to 7 days at the lateral mitral annulus(MA),basal septum,and lateral tricuspid annulus(TA) during ventricular systole(Sa),early diastole(Ea),late diastole(Aa).Tansmitral and transtricuspid inflow were also obtained through pulsed doppler echocardiography.Results Ea and Sa in all of 3 locations were lower in the premature group compared with that of the full-term group,and Ea/Aa in TA was lower in premature group,but Aa and E/Ea showed no difference between 2 groups.Ea and Sa showed a positive correlation with gestational age and birth weight.Conclusions Ventricular systolic and diastolic function in premature infants are poorer than that in full-term infants in the early stage of neonatal period,and ventricular function is related to intra-uterus growth and maturity of the newborn.Diastolic function of the left ventricle in both groups develops rapidly during the early stage of neonatal period.

Objective To investigate the changes and significance of concentration of soluble intercellular adhesion molecule-1(sICAM-1) in cerebrospinal fluid (CSF) of bacterial meningitis(BM) in rabbits. Methods A total of 36 rabbits were randomly divided into m eningitis group, meningitis cefotaxime-treated group and control group. BM indu ced by escherichia coli(Ec) via cerebellomedullary cistern inoculated. Normal sa line was injected in control group. CSF was sampled in different time. The conce ntration of CSF sICAM-1 was detected by ELISA.Results 1.There was a low concentration of sICAM-1 in CSF in 85 percent of normal rabbi ts.2.In meningitis group, there was a sharp rise in the concentration of CSF sIC AM-1 at 6 hours after Ec was inoculated, reached a peak level at 12 hours, and t here was higher concentration of CSF sICAM-1 between 6 and 24 hour than that at 0 hour.3.In meningitis cefotaxime-treated group, the concentration of CSF sICAM -1 at 6 hour and 12 hours was similar to meningitis group, the time that get pe ak level was at 24 hours that at 12 hours after making use of antimicrobial agen t.The peak level was higher than meningitis group. The concentration of CSF sICA M-1 decreased markedly at 48 hours that made use of antimicrobial agent 36 hour s later,but the concentration was still higher than the peak level of meningitis group.Afterwards, with the time of making use of antimicrobial agent lengthened ,the concentration of CSF sICAM-1 decreased gradually.4.Experimental results in dicated by correlating analysis to these data that there was positive correlatio n in the concentration of CSF sICAM-1 with the brain water content.Conclusions sICAM-1 participates in the pathological process of BM, and contributes to the damage of blood brain barrier and the formation of brain edema.There is importan t significance that drugs which can resist the discharge of sICAM-1 will be impl ied.

Phorbol ester-induced release of growth hormone (GH) and prolactin (PRL) from human somatotrophic tumors was examined in vitro. 12-O-tetradecanoyl-phorbol-13- acetate (TPA)strongly stimulated GH and PRL secretion and showed an additive effect on GH secretion if used in combination with GH releasing hormone (GHRH). In contrast, staurosporine exerted a variable inhibitory effect on GH release. There was no correlation between such effects and gsp mutations.The findings suggested that TPA doesn't act directly through cAMP signal transduction system.
