Objective: To further analyze and identify effective components of anti-asthma in acupuncture serum.

Methods: Changes of eosinophils in the peripheral blood of rats with eosinophilia were observed for 10 days after intravenous injection of the different segments of serum (serum: normal saline = 1:20, 2.5 mL/kg, from the first day of the model establishment, for 3 consecutive days).

Results: After intravenous injection of different segments of serum, the eosinophil counts in the peripheral blood decreased significantly from the 3rd day as compared with those of the model group (P<0.05).

Conclusion: The effective components of acupuncture serum from asthmatic rats treated by acupuncture for eosinophils are not a single component, and acupuncture stimulation may produce many kinds of components of anti-asthma.

Low-Dose Oral Ginger Improves Daily Symptom Scores in Asthma.

Pharmaceuticals (Basel)

December 2024

Department of Medicine (Pulmonology, Allergy and Critical Care), Columbia University Vagelos College of Physicians and Surgeons, New York, NY 10032, USA.

A significant number of individuals with asthma have poorly controlled daily symptoms and utilize dietary supplements such as ginger in a quest for improved symptom control; however, its effectiveness at improving the control of symptoms is unproven. We questioned whether low-dose oral ginger would improve subjective and objective measurements of asthma control in mild-to-moderate asthmatics. We performed a randomized, placebo-controlled, double-blinded study of a low dose (1 g twice daily) of a dietary supplement of ginger in 32 mild-to-moderate uncontrolled asthmatics over a 2-month trial period while maintaining daily conventional asthma therapies.

Adjuvant Effect of in Sublingual Immunotherapy of Asthmatic Mice.

Pharmaceuticals (Basel)

November 2024

Department of Pathogen Biology and Microecology, School of Basic Medical Sciences, Dalian Medical University, Dalian 116044, China.

: Sublingual immunotherapy (SLIT) has shown promise in mitigating allergic asthma symptoms; nevertheless, its high dose and prolonged duration of treatment raise safety concerns. This study explored the potential of () to enhance the effectiveness of SLIT in a mouse model of allergic asthma. : Allergic asthma was induced in Balb/c mice following sensitization and challenge with a house dust mite (HDM) allergen.

Der p1 is one of the major allergens causing house dust mite (HDM) allergy. Pathological Der p1-specific B cells play a key role in allergic inflammation as producers of allergen-specific antibodies. Crosslinking the inhibitory FcγRIIb with the B cell receptor triggers a high-affinity suppressive signal in B cells.

Eosinophils are central inflammatory cells in asthma; however, a portion of patients with chronic obstructive pulmonary disease (COPD) have blood or sputum eosinophilia, a condition termed eosinophilic COPD (eCOPD), which may contribute to the progression of the disease. We hypothesize that eosinophilic inflammation in eCOPD patients is related to Type 2 (T2)-high inflammation seen in asthma and that serum mediators might help us to identify T2-high inflammation in patients and choose an appropriate personalized treatment strategy. Thus, we aimed to investigate ten serum levels of T2-high inflammation mediators in eCOPD patients and compare them to severe non-allergic eosinophilic asthma (SNEA) patients.

A Combined Extract from and Mitigates PM-Induced Respiratory Damage by NF-κB/TGF-β1 Pathway.

Antioxidants (Basel)

December 2024

Division of Applied Life Science (BK21), Institute of Agriculture and Life Science, Gyeongsang National University, Jinju 52828, Republic of Korea.

This research evaluated the protective role of a combined extract of and (DBZO) against respiratory dysfunction caused by particulate matter (PM) exposure in BALB/c mice. The bioactive compounds identified in the DBZO are catechin, astragalin, 6-gingerol, 8-gingerol, and 6-shogaol. DBZO ameliorated cell viability and reactive oxygen species (ROS) production in PM-stimulated A549 and RPMI 2650 cells.
