Background and Objectives: Asthma is one of the most common respiratory diseases. Inhaled particles that may trigger allergic reactions and air routes are important factors contributing to asthma. This study aimed to determine the abundance of allergens in children with asthma in Gorgan, Iran.
Methods: In this retrospective study, we randomly collected records of all asthmatic patients over five years of age referred to asthma and allergy clinic in Gorgan, Iran. Furthermore, data related to skin prick test were recorded.
Results: The severity of asthma differed significantly between males and females. There was a direct relationship between age and reaction to one allergen. In addition, 18 of 25 (72 %) patients with severe asthma were allergic to more than two allergens. Moreover, the most common allergen was mite (56%).
Conclusion: Mites are the most common allergen among children with asthma in the study area.

Background: This study investigated the impact of a 3-week detraining period, followed by 10 weeks of aerobic training, on the serum levels of osteocalcin and alkaline phosphatase (ALP) in asthmatic males.
Methods: Thirty adult males with asthma were randomly divided into experimental and control groups. The experimental group engaged in a 10-week aerobic training program, which included running sessions 3 times per week for 30-60 minutes each, maintaining a target heart rate range of 55%-75% of their maximum heart rate (HRmax). In contrast, the control subjects did not participate in any exercise activities during the study period. Fasting blood samples were obtained at baseline, after aerobic training, and after detraining to measure the levels of osteocalcin and ALP in both groups.
Results: The 10-week aerobic training program led to a significant increase in levels of osteocalcin and ALP in the experimental group, but following the detraining period, these variables returned to their pre-training levels.
Conclusion: The effectiveness of continuous aerobic training on bone formation markers in asthmatic patients will disappear after a relatively short period of detraining. This evidence emphasizes the lack of stopping aerobic exercise in the presence of inhaled corticosteroids with the aim of improving bone metabolism in asthmatic patients.
