METHODS: Monoclonal antibody PD4, which specifically recognizes a distinct protein from mycoplasma hyorhinis, was used to detect mycoplasma infection in different paraffin embedded carcinoma tissues with immunohistochemistry. PCR was applied to amplify the mycoplasma DNA from the positive samples for confirming immunohistochemistry. RESULTS: Fifty of 90 cases (56%) of gastric carcinoma were positive for mycoplasma hyorhinis. In other gastric diseases, the mycoplasma infection ratio was 28% (18/49) in chronic superficial gastritis, 30% (14/46) in gastric ulcer and 37% (18/49) in intestinal metaplasia. The difference is significant with gastric cancer (chi(2) = 12.06, P 【 0.05). In colon carcinoma, the mycoplasma infection ratio was 55.1% (32/58),but it was 20.9% (10/49)in adenomarous polyp (chi(2)=13.46, P 【 0.005). Gastric and colon cancers with high differentiation had a higher mycoplasma infection ratio than those with low differentiation (P 【 0.05). Mycoplasma infection in esophageal cancer, lung cancer, breast cancer and glioma was 50.9% (27/53), 52.6% (31/59), 39.7% (25/63) and 41% (38/91), respectively. The mycoplasma DNA was successfully amplified with the DNA extracted from the cancer tissues that were positive for mycoplasma infection (detected with antibody PD4). CONCLUSION: There was high correlation between mycoplasma infection and different cancers, which suggests the possibility of an association between the two. The mechanism involved in oncogenesis by mycoplasma remains unknown.展开更多

METHODS:Seventy-two lung cancer patients(55 males and 17 females,aged 58.2±11.7 years)and 68,age and gender-matched,control subjects were enrolled.All subjects underwent an enzyme-linked immunosorbent assay IgG serologic test for Hpylori diagnosis. RESULTS:A correlation between age and HpyloriIgG level was detected for both lung cancer patients(r=0.42, P=0.004)and controls(r=0.44,P=0.004).Seropositivity for Hpyloridid not differ significantly between patients with lung cancer and controls(61.1% vs 55.9%,P>0.05). Concerning the mean serum concentration of IgG antibodies against Hpylori,no significant difference between the two groups was detected(32.6±19.1 vs 27.4±18.3 U/mL, P>0.05). CONCLUSION:No significant association between Hpylori infection and lung cancer was found.展开更多

For this reason, many physicians have dismissed ozone therapy and limited funds have been delegated to furthering the knowledge of its therapeutic effects. However, there is evidence that suggests that ozone does have various therapeutic effects that range from disinfection of pathogens, anticancer properties, and treatment of back ailments. In this paper, we have collected the more promising studies that suggest the efficacy and safety of ozone therapy primarily focusing on autohemotherapy. This paper is designed to promote awareness of ozone therapy and to show some supporting evidence of its efficacy. Clinically, ozone therapy is often used adjunctively and combined with other treatment modalities to enhance or encourage a desired mechanism of action. Since the efficacy of ozone alone is still contentious, it is important to note that ozone therapy should be used in conjunction with other various treatments with very few exceptions.展开更多

Clinical suspicion arose due to the need for supplementary oxygen and persistent fever during treatment for community-acquired pneumonia. The diagnosis was confirmed by chest computed tomography. Although necrotizing pneumonia typically requires major surgical intervention upon diagnosis, we chose conservative management with antimicrobials and chest drainage alone. The patient experienced significant improvement and resolution of pneumonia with conservative management.展开更多
