The result indicated that K1 can inhibit R. Solanacearum growth entirely, at the concentration range from 1/50 to 1/5000. K2 can reach the same result at the concentration range from 1/50 to 1/50000. Compared with the control plates, K1, at the concentration 1/50000, had no significant differences, and the average number of colony per plate was 112-115. The immature tobacco shown wilt as soon as inoculated with R. Solanacearum, and recovered gradually after using K1, K2. The densities of microbial suspension, handled by K1, K2 within 10 hs, were both significantly lower than the controlled ones. The optical microscopy also shown that handled microbial body differed from the controlled, whose body was regular short, rod shape as opposed to the handled ones with irregular rod shape and damaged body. All the results indicated that K1 and K2 both had inhibitory effects on tobacco R. Solanacearum, and K2 was more efficient than K1.展开更多

In general, prognosis in such patients is poor due to the development of protein-energy wasting(PEW). Therefore, it is important to clarify the etiology of PEW and to establish better strategies to deal with this condition. Chronic Helicobacter pylori(H. pylori) infection in the gastric mucosa has a close association with not only the development of peptic ulcer disease and gastric cancer, but is also associated with abnormal plasma and gastric mucosal ghrelin levels that are seen in malnutrition. It is unclear whether H. pylori infection of the gastric mucosa is directly associated with prognosis in HD patients by affecting ghrelin levels. Recent studies show that the prevalence of H. pylori infection in HD patients is significantly lower than in subjects with normal renal function. In the natural history of H. pylori infection in HD patients, the prevalence of infection decreases as the length of time on HD increases. The severity of gastric mucosal atrophy has been suggested as the major determinant of ghrelin levels in these patients, and eradication therapy of H. pylori improves nutritional status by increasing serum cholinesterase and cholesterol levels, especially in patients with mildto-moderate gastric mucosal atrophy. Prompt H. pylori eradication to inhibit the progress of gastric atrophy may be required to prevent this decrease in ghrelin levels and subsequent PEW and improve the prognosis of HD patients by improving their nutritional status.展开更多

We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication. METHODS:One hundred and sixty-four H pylori positive patients (68 males,96 females;mean age:48±12 years) with duodenal or gastric ulcer without a smoking history were included in the study.The patients were divided into three groups according to the treatment regimens.Omeprazole 20mg,clarithromycin 500mg,amoxicillin 1g were given twice daily for 1 week (Group Ⅰ) and 2 weeks (Group Ⅱ). Patients in Group Ⅲ received bismuth subsitrate 300mg, tetracyline 500mg and metronidazole 500mg four times daily in addition to Omeprazole 20mg twice daily.Two biopsies each before and after treatment were obtained from antrum and corpus,and histopathologically evaluated. Eradication was assumed to be successful if no H pylorus was detected from four biopsy specimens taken after treatment.The effects of factors like age,sex,H pylori density on antrum and corpus before treatment,the total H pylori density,and the inflammation scores on the rate of H pylori eradication were evaluated. RESULTS:The overall eradication rate was 42%.The rates in groups Ⅱ and Ⅲ were statistically higher than that in group Ⅰ (P<0.05).The rates of eradication were 24.5%, 40.7% and 61.5% in groups Ⅰ,Ⅱ and Ⅲ,respectively.The eradication rate was negatively related to either corpus H pylori density or total H pylori density (P<0.05).The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55 yr vs 39 yr,P<0.001).No correlation between sex and H pylori eradication was found. CONCLUSION:Our rates of eradication were significantly lower when compared to those reported in literature.We believe that advanced age and high H pylori density are negative predictive factors for the rate of H pylori eradication.展开更多

There is no specific therapy for the disease at present. In the past few years, 23 cases of atrophic rhinitis were treated mainly by deep puncture at three points in the nasal region with satisfactory results. In order to find out the functional changes of the nasal mucosa, the mucociliary transport rate (MTR), surface temperature of the conchal mucosa, acid-base scale of nasal secretion, and volume of nasal secretion were determined before and after the treatment.展开更多
