Lipopolysaccharides (LPSs) from Leptospira interrogans serovar hardjo (reference strain hardjoprajitno and strain hardjobovis) were prepared by the hot phenol-water procedure. High yields of LPSs were found in the phenol phase. Gel electrophoresis of the phenol phase LPSs showed similar patterns for all strains in contrast to the different patterns found in(More)
AIMS To evaluate long-term results of patients with small solitary hepatocellular carcinoma (HCC) and well-preserved liver function who received radiofrequency ablation (RFA) as first-line treatment. MATERIALS AND METHODS Between November 1999 and June 2007, 247 patients with solitary HCC ≤5 cm and liver status scored as Child-Pugh class A were enrolled.(More)
OBJECTIVE Coronary heart disease (CHD) is a frequent medical condition in developed countries and is one of the most serious diseases threatening patients' lives. Perioperative myocardial infarction is the major cause of perioperative cardiac death and cardiac arrest, but is difficult to be precisely identified by observing clinical symptoms or assessing(More)
Since 1955, Leptospirosis has been recognized as a notifiable infectious disease in China. According to the data gathered from 26 provinces of China (except for Taiwan) in 1955-1993, the average morbidity and mortality were 7.08/10(5) and 1.02% respectively. Distribution of the disease involved 26 provinces in China (not including Taiwan). The trend of the(More)
A magnetically stabilized fluidized bed (MSB) is a highly efficient filter that takes the advantage of both fluidized beds and fixed beds. This paper presents the research to collect aerosol in airflow with a MSB. The filtering model of MSB is established with its parameters including magnetic field intensity, gas superficial velocity, average grain-size,(More)

Seventy-nine sero-samples from patients with leptospirosis were tested by dot-ELISA and microscopical agglutination test (MAT). Results showed that the accordance rate was 96.19%. 20 sero-samples obtained from healthy people, 4 from hepatitis B(HBV) and 4 from epidemic hemorrhage fever (EHF) were negative by dot-ELISA. We believe dot-ELISA is a simple,(More)
Urine samples of Leptospires from cattle were detected by polymerase chain reaction (PCR) and isolation. Positive rates by Southern-blot and agarose gel electrophoresis of PCR amplification productions were 13% and 11% respectively. Positive rate of isolation was 3.1%. Various positive rates by PCR for cattle urine from different areas were discovered.(More)
