To investigate the infection status of pigs with Cryptosporidium parvum, 589 fecal samples were collected from pigs raised at farm in Chungcheongbuk-do and Chungcheongnam-do. Of the 589 pig fecal samples, 62 (10.5%) were positive for C. parvum. The area showing the highest positive rate was Dangjin-gun, Chungcheongnam-do (14.0%), and the lowest (0%) Salmi-myon, Chungcheongbuk-do. The positive rate of C. parvum in Judok-eup increased from 12.7% in the winter to 22.1% in the summer. The results of this study suggest that the pigs may be a source of human C. parvum infection.

The mesenchymal stem cell ( MSC ) is an important component of the hematopoietic microenvironment .In the process of stem cell transplantation (SCT), MSC can restore the hematopoietic microenvironment , improve the capacity of hematopoiet-ic reconstitution, reduce the incidence of graft versus host disease (GVHD).MSC has been widely used in hematopoietic stem cell transplantation, immune therapy, tissue engineering and many other fields .The distribution and colonization of MSC in vivo directly af-fect the effectiveness of transplantation .Improving the homing and engraftment of MSC may obtain a better therapeutic effect .Further research on the mechanism and influential factors of MSC homing may lead to the development of therapies and promote clinical applica -tions of MSC.This paper reviews the recent progress in homing mechanism of MSC .

Amyotrophic lateral sclerosis(ALS)is a rare progressive motor neuron disease.Sialorrhoea is one of the common symptoms which influenced the patient's quality of life.This paper reviewed the treatments for sialorrhoea in ALS patients.

Objective To establish the nursing care for the patients with pulse steroid therapy, and to investigate its effect. Methods 78 patients who accepted pulse steroid therapy in the past 4 years were analyzed retrospectively, in which, 42 within past 2 years （2008 and 2007) were as pulse steroid nursing care group, and other 36 patients before 2 years (2007 and 2006) were as routine nursing care group. Results 3 weeks after the pulse steroid therapy, in pulse steroid nursing care group, proximal muscle weakness were found in 8 patents, insomnia in 18 patients; while in routine nursing care groups, proximal muscle weakness were found in 16 patents, and insomnia in 25 patients（P<0.05）. Conclusion Pulse steroid nursing care can reduce the incidence of muscle weakness and insomnia after pulse steroid therapy significantly.

Objective struclured clinical examination (OSCE) is a kind of examination which could objectively evaluate the students′clinical skills.Nowadays,OSCE are wildly applied in medical educational field throughout the world.Timely discussion and analysis on the problems existed in the implementation process of OSCE is necessary.Measures should be taken to improve the OSCE examination and to meet the requirements of higher clinical practice training level such as increasing clinical skill simulation training hardware investment,optimizing settings and conlents of the examination and the test stations as well as introducing standardized patients (SP) and other measures.

Aim To further research into the antithrombotic mechanism of scorpion venom active peptides (SVAP). Methods Human umbilical vein endothelial cells (HUVEC) were cultured with enzyme digestive method. After the cultured HUVC was incubated in conditioned media for 1 hour, the effects of SVAP on the concentration of 6-Keto-PGF 1? and NO of HUVEC were determined with radioactive-immunolygic and nitrate reduction enzyme method respectively. Results As compared with control, SVAP in the doses of 1,5,10, 20 mg?L -1 had the distinctive increase of 54%, 68%,72%,79% of the concentration of 6-Keto-PGF 1? and SVAP in the doses of 10, 20 mg?L -1 had the significantly increased of 27%, 46% of the concentration of NO. Regression anylysis showed that the release levels of PGI 2 and NO in HUVEC induced by SVAP was of positive correlation. Conclusion Antithrombotic mechanism of SVAP is related to the increase of PGI 2 and NO released from HUVEC and synergistic and mediating action between NO and PGI 2.
