In practice is not always possible to determine which virus caused the aggravation of asthma and, accordingly, to study its effect on the course of the disease. In experimental studies have shown that viruses (particularly intense rhinovirus) increase bronchial reactivity, a key feature of asthma. Bronchial hyperreactivity after rinovirusnoy infection can be up to 15 days to
buy amoxicillin; rinovirusnaya infection increases the risk of late allergic reactions and the severity of components such as increased secretion of mast cells, increased influx of eosinophils in the bronchial mucosa, decreased sensitivity of beta-adrenergic receptors. Viruses can increase cholinergic activity by increasing the response to airway vagal stimulation, non-specific triggers.
To date, there is a view that children with rhinovirus causes obstruction, have to
buy amoxicillin online, and the virus causes the manifestation of the disease, worsens the disease. In the diagnosis of asthma in this group of children help to the following criteria: recurrence of obstruction during the year, more than three times, the protracted nature of obstruction, a good response to bronchodilator therapy, often burdened by heredity of allergic diseases, early allergic manifestations in the child
buying amoxicillin.
