[Method] Through ar- tificial injection of allantoic liquid containing ILTV into chickens to induce infectious laryngotracheitis, the clinical symptoms in infected chickens were observed; tissues of trachea, lungs, heart, liver, kidney and spleen were collected from dead chickens, and prepared into paraffin sections, followed by histopathological observation under a microscope. [Results] This disease occured in the inoculated chickens 3d later, with a morbidity rate of 95%. The main symptoms were dyspnea, asthma and coughing up of bloody exudate; yellowish-white pseudomembrane was observed on dissected larynx trachea; swelling, haemorrhage, and further erosion were observed on the in- fected tracheal mucosa, resulting in death of chickens, with the mortality rate of 25%; histopathological observation showed that parenchymal organs exhibited exuda- tive inflammation; swelling, degeneration, necrosis and shedding of epithelial cells were observed; disturbance of blood circulation occured.[Conclusion] This study pro- vides reference bases for the treatment of ILT.展开更多

Clinical research has shown that the capsule has a good curative effect on chronic gastritis related to pyrolic Helicobacterium. Among the 53 cases in the treatment group, clinical observation showed cure in 6 cases, obvious effect in 18 cases, effect in 24 cases, no effect on 5 cases, with a total effective rate of 90.5%. Of the 50 cases in the control group, cure was found in 5 cases, obvious effect in 13 cases, effect in 20 cases, no effect in 12 cases, the total effective rate being 76%. The total effective rate in the treatment group was higher than that in the control group. The rate of eliminating pyrolic Helicobacterium in the treatment group was 66.04%, similar to that in the control group. In a follow-up visit 6 months later, the recurrence rate in the treatment group was 13.33%, obviously lower than that of 41.66% in the control group.展开更多
