The growth and pigment production of 47 strains on casein medium were studied comparatively.T4 and Neurospora crassa AS 3.1602 were selected for their capacity of producing melanin on five different culture media. Melanin produced by T4 was investigated, and T4 was identified as Proteus mirabilis primarily.

Objective To investigate the effect of pyrrolidine dithiocarbamate(PDTC) on monocyte chemotactic protein1 (MCP-1) in rejection of cardiac allograft and its mechanisms.Methods Heterotopic cervical heart transplantation was performed by cuff-technique.The SD rat recipients were randomly divided into 3 groups:AR group (Acute rejection,n =12),both the recipients and donors were without any treatment.CsA group(n =12),the recipients were treated with 10 mg/kg cyclosporine A after transplantation.PDTC group(n =12),the recipients were treated with 100 mg/kg PDTC after transplantation.All the cardiac allografts were harvested at different time post transplantation according to requirements.We studied allograft myocardial fibrosis wih the help of Masson stain,immuno-histo-chemistry and western blot also were used to detect the expression of MCP-1.Results The survival time of the cardiac allografts was significantly longer in PDTC group than in acute rejection group and CsA group(P ＜ 0.01),and myocardial fibrosis of cardiac allografts in PDTC group was significantly decreased (P ＜ 0.01).The IOD in PDTC group was markedly lower than in CsA group (P ＜ 0.01).Conclusion As the inhibitor of NF-κB,PDTC can significantly relieve rejection of cardiac allograft by inhibiting the expression of MCp-1.

Baculovirus has many advantages as vectors for gene transfer. We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP (Ac-CMV-GFP) could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter. MTT assay suggested that both Ac-CMV-p35 and Ac-CMV-GFP did not have cytotoxic effect on human embryo kidney 293 cells. Cell growth curve showed the Ac-CMV-p35 and Ac- CMV-GFP transduced and non-transduced cells had similar proliferation rate, so baculovirus-mediated p35expression had no adverse effect on cell proliferation. In addition, baculovirus-mediated p35 gene expression protected human embryo kidney 293 cells against apoptosis induced by various apoptosis inducers such as Actinomycin D, UV or serum-free media. These results suggested that the baculovirus vector mediated p35 gene expression was functional and it could be widely used in molecular research and even gene therapy.

Objective To evaluate the cost-effectiveness of early enteral nutrition (EEN) in elder patients undergoing gastrectomy for gastric carcinoma. Methods An outcome-based retrospective review of 52 patients who had undergone gastrectomy for gastric carcinoma between July 1999 and June 2002 was performed .There were 27 patients in the EEN group, and 25 in the TPN group. Results The mean postoperative hospital days of the EEN group was significantly less than that of the TPN group (16.3 d vs. 21.3 d, t =4.6814, P

ObjectiveTo observe the effect of sport walking on heart and lungs functions in old women.MethodsForty-two old women aged from 60 to 69 had sport walking for 4 months; the speed and intensity were controlled according to their heart rate respectively. The indexes of respiration, circulation and rheoencephalography were measured before and after exercise.ResultsAfter exercise, blood-pumping function of heart improved obviously, stroke volume increased from (65.22±11.41)ml to (72.10± 10.78)ml, ejection fraction increased from (60.10±5.03)% to (68.78±6.25)%, while heart rate declined from (77.45±8.69) times/min to (7.89±8.21)times/min, capacity increased from (2.86±0.36)L to (3.34±0.53)L, and maximal voluntary ventilation for every minute increased from (96.14± 15.21)L to (114.02±16.01)L, significantly different compared with that before treatment ( P<0.01). The fluid time of rheoencephalography reduced from (0.171±0.058)s to (0.128±0.049)s ( P<0.01).ConclusionSport walking under proper intensity can improve the function of respiration and circulation system in old women, so it is a good way to keep health for the elders.

Objective The study aimed to explore the relationship between AIF related pathway and the inju-ring of cultured SGNs (spiral ganglion neurons)by glutamate toxicity,and to find AIF expression and distribution changes in SGNs.Methods SGNs of 40 newborn rats within 3 day were obtained and cultured in vitro.Cultured cells were divided into four groups:the normal control group,10 mM,20 mM and 40 mM glutamate injured group, separately.After 48 h hours culturing,optical microscopy,immune fluorescence staining and real-time fluores-cence quantitative PCR were used to observe the morphology,AIF distribution,and AIF,calpain,Caspase3 expres-sion changes in SGNs in vitro.TUNEL was used to verify the cell apoptosis.ResuIts Noticeable morphological chan-ges and cell apoptosis were occurred in 20 mM glutamate group,with AIF nuclear translocation.AIF gene expression was significantly higher than normal after glutamate administration (P<0.05);moreover,calpain gene expression increased(P<0.05);but caspase3 expression was not statistically significantly increased in all glutamate treated groups (P>0.05). ConcIusion In the process of cultured SGNs injured by glutamate,AIF participated in the cell apoptosis.Noticeable cell apoptosis were occurred in 20 mM glutamate group with AIF nuclear translocation.Calpain up-expression also contributed to excitatory neurotransmitter injury on SGNs,but Caspase 3 had no obvious effects.
