[Method] An inflammation model was established by xylene-induced inflammation test and carrageenan- induced inflammation test to analyze the anti-inflammatory effect of compound sarcandra aerosol. By bacteriostasis test in vitro, the antibacterial effect of compound sarcandra aerosol against five common pathogens of pharyngitis was investigated. Blood samples were collected from Wistar rats in different compound sarcandra aerosol groups and control group to compare blood routine indicators and interleukin-1 (IL-1) levels. [Result] Three different concentrations of compound sarcandra aerosol could reduce degrees of xylene-induced ear edema in mice and carrageenan- induced paw edema in rats, but the anti-inflammatory effect of compound sarcandra aerosol was reduced as the concentration declined. In bacteriostasis test in vitro, the minimum inhibitory concentration of compound sarcandra aerosol against Streptococcus pneumoniae, Streptococcus hemolytis, Corynebacterium diphtheriae, Staphylococcus aureus and Salmonella typhimurium was 76, 105 38, 65 and 30 mg/ml, respectively. Compound sarcandra aerosol reduced white blood cell count, neutrophil count and lymphocyte percentage in pharyngitis model rats. Moreover, interleukin-1 level in watermelon frost lozenge group and different compound sarcandra aerosol groups was lower compared with control group. [Conclusion] Compound sarcandra aerosol can effectively treat pharyngitis by exerting anti-inflammatory and antibacterial effect and reducing interleukin-1 level. This study laid a solid foundation for clinical application of compound sarcandra aerosol.展开更多

The infection is associated with a number of hepatobiliary diseases, including cholangitis, obstructive jaundice, hepatomegaly, cholecystitis and cholelithiasis. Multi-factorial etiology of cholangiocarcinoma, mechanical damage, parasite secretions, and immunopathology may enhance cholangiocarcinogenesis. Moreover, both experimental and epidemiological evidences strongly implicate liver fluke infection as the major risk factor in cholangiocarcinoma, cancer of the bile ducts. The liver fluke infection is induced by eating raw or uncooked fish products that is the tradition and popular in the northeastern and northern region, particularly in rural areas, of Thailand. The health education programs to prevent and control opisthorchiasis are still required in the high-risk areas.展开更多

Many of the genetic insults driving this MDC sequence have recently been characterized, providing targets for candidate biomarkers with potential clinical utility to stratify risk in individual patients. Many clinical risk factors have been investigated, and associations with a variety of genetic, specific gastrointestinal and other modifiable factors have been proposed in the literature. This review summarizes the current understanding of the mechanisms involved in neoplastic progression of BE to EAC and critically appraises the relative roles and contributions of these putative risk factors from the published evidence currently available.展开更多

We report the curative treatment of a case of pineal parenchymal tumor of intermediate differentiation with spontaneous apoplectic hemorrhage. This case is shown through computed tomography and magnetic resonance imaging of the brain, and is confirmed via histopathological studies. Recurrent upward gaze paresis was observed after the stereotactic biopsy. The paresis required an expeditious tumor resection. The mechanism of the pineal apoplectic hemorrhage remains unclear although it has been observed in different pineal region lesions. Clinical and radiological evidence of the cure 5 years post-surgery is available.展开更多

Purified further by avicel column chromatography and preparative thin layer chromatography. Combretin was investigated for anti-mycobacterium and anti-cancer activities. Combretin was inactive against Mycobacterium tuberculosis but showed anti-cancer activities against human hepatocarcinoma (Hep G2) ATCC HB-8065 and human caucasian colon adenocarcinoma (Caco2) ATCC HTB-39 at concentration greater than 300 mcg/ml in DMSO (Dimethyl sulfoxide).展开更多

METHODS: We conducted a population-based, large- scale case-control study including 2213 GCs, 1829 CRCs, and 1699 controls. Null and non-null genotypes of GSTM1 and GSI-F1 were determined using realtime PCR. RESULTS: The null genotypes of GSTM1 and GSTT1 were not significantly associated with elevated risk of gastric (OR = 1.070, 95% CI = 0.935-1.224; OR = 1.101, 95% CI = 0.963-1.259, respectively) or colorectal cancer (OR = 1.065, 95% CI = 0.923-1.228; OR = 1.041, 95% CI = 0.903-1.200, respectively). The frequency of the combined null GST genotype was not different between the two cancer groups and controls. Moreover, smoking, drinking, and age did not modify the association between these genotypes and the risk of gastric or colorectal cancer. CONCLUSION: GSTM1 and GSCI-1 null genotypes were not associated with increased risk of GC or CRC in Koreans.展开更多
