Abstract

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) represent critical events in disease progression, yet their complex pathophysiology remains incompletely understood. Understanding the mechanisms underlying these exacerbations is essential for developing effective therapeutic strategies and improving patient outcomes. This literature review aims to synthesize current knowledge on the cellular and molecular mechanisms driving acute exacerbations of COPD, highlighting the importance of utilizing appropriate animal models for future research. This review identified rodent models, particularly mice (C57BL/6 strain) and rats (Sprague-Dawley) are predominantly employed due to their genetic tractability and physiological relevance, with occasional use of guinea pigs for airway hyperresponsiveness studies. Combined approaches using cigarette smoke exposure followed by inflammatory triggers (LPS, viral infections) showed the highest translational relevance. Key pathophysiological mechanisms studied include neutrophilic inflammation, oxidative stress, airway remodelling, and mucus hypersecretion. Current animal models provide valuable insight into AECOPD pathophysiology but face limitations in fully recapitulating human disease complexity. Future directions should focus on incorporating comorbidities, aging, and standardized outcome measures.

Abstract

Daun Jambu bol (Syzygium malaccense (L.) Merr. & L.M.Perry) memiliki senyawa polifenol seperti flavonoid, asam fenolat dan tannin telah dianggap sebagai antioksidan. Penelitian ini bertujuan menguji aktivitas antioksidan ekstrak etanol 70% daun jambu bol (Syzygium malaccense (L.) Merr. & L.M.Perry) berdasarkan parameter kadar malondialdehid (MDA) dan aktivitas superoksida dismutase (SOD). Mencit dibagi menjadi 6 kelompok yaitu: kelompok kontrol normal, kelompok kontrol negatif, kelompok kontrol positif diberikan vitamin C (2,6 mg/20gBB), dan 3 kelompok dosis ekstrak etanol 70% daun jambu bol (5; 10; 20 mg/20gBB). Pengukuran kadar MDA dilakukan dengan metode TBARs dan pengukuran aktivitas SOD dilakukan dengan metode Adrenochrome Assay. Hasil pengukuran kadar MDA pada kelompok normal, kelompok kontrol negatif, kelompok kontrol positif, kelompok dosis 5 mg/20gBB; 10 mg/20gBB; 20 mg/20gBB secara berturut-turut adalah 2,4814 nmol/mL; 5,0557 nmol/mL; 3,0153 nmol/mL; 4,7122 nmol/mL; 4,1289 nmol/mL; 3,5013 nmol/mL sedangkan untuk hasil pengukuran aktivitas SOD pada hati mencit adalah 124,9967 U/mL; 60,34 U/mL; 188,76 U/mL; 129,31 U/mL; 148,85 U/mL; 168,9667 U/mL. Kesimpulan hasil yang didapatkan adalah ekstrak etanol 70% daun jambu bol (Syzygium malaccense (L.) Merr. & L.M.Perry) memiliki potensi antioksidan dengan menurunkan kadar MDA dan meningkatkan aktivitas SOD.

Abstract

Allergic airway inflammation is commonly associated with eosinophilic infiltration and epithelial remodeling, which impair respiratory function and contribute to tissue damage. This study investigated the therapeutic potential of the ethanol extract of Nigella sativa in an ovalbumin-induced rat model of allergenic airway response. Ethanol extracts were tested in an ovalbumin-induced rat model using Sprague-Dawley rats (n=36), comparing normal, negative controls, 0.009 mg/g BW salbutamol (positive control), and three inhaled extract doses (12.25, 24.50, 49 g/kg BW). Comprehensive analysis included physiological parameters (oxygen saturation), inflammatory biomarkers (lung eosinophil count), and pulmonary histopathology (epithelial thickness). The highest dose (49 g/kg) matched salbutamol in improving oxygen saturation (86.75% vs. 88%, p=0.9917) and reducing epithelial thickness (81.50 µm vs. 81.75 µm, p=0.9999), while suppressing eosinophil infiltration (0.73 vs. 1.45 cells/field, p=0.3348). These results confirm Nigella sativa’s efficacy in attenuating airway inflammation via eosinophil-targeted mechanisms without structural epithelial alterations. The study validates traditional applications of Nigella sativa and proposes an evidence-based framework for integrating phytotherapy into respiratory medicine.

Abstract

Daun lobak (Raphanus sativus L.) mengandung senyawa flavonoid yang memiliki aktivitas sebagai antioksidan. Penelitian ini bertujuan untuk menguji efek antioksidan ekstrak etanol 70% daun lobak (Raphanus sativus L.) berdasarkan parameter kadar malondialdehid (MDA) dan aktivitas superoksida dismutase (SOD). Penelitian menggunakan mencit dibagi menjadi 6 kelompok yaitu: kelompok kontrol normal (I), kelompok kontrol negative (II), kelompok kontrol positif (III) (vitamin C 2,6 mg/20 gBB), dan 3 kelompok (IV,V,VI)dosis ekstrak etanol 70% daun lobak (Raphanus sativus L.) (5,6; 11,2; 22,4 mg/20 gBB). Pengukuran kadar MDA dilakukan dengan metode Wills dan pengukuran aktivitas SOD dilakukan dengan metode Adrenochrome Assay dan Analisa menggunakan uji ANOVA. Hasil pengukuran kadar MDA pada kelompok normal, kelompok kontrol negatif, kelompok kontrol negatif, kelompok kontrol positif, kelompok dosis 5,6 mg/20 gBB; 11,2 mg/20 gBB; 22,4 mg/20 gBB secara berturut-turut adalah 2,1617 nmol/mL; 5,3075 nmol/mL; 2,3331 nmol/mL; 4,5583 nmol/mL; 3,5957 nmol/mL; 2,6702 nmol/mL sedangkan untuk hasil pengukuran aktivitas SOD hati mencit adalah 124,2383 U/mL; 65,64 U/mL; 176,7583 U/mL; 106,045 U/mL; 134,34 U/mL; 153,53 U/mL. Kesimpulan penelitian ini adalah terdapat perbedaan bermakna antara kelompok III dengan kelompok IV,V,VI  dalam peningkatan aktivitas SOD dan penurunan kadar MDA (p<0,05) yaitu memiliki potensi antioksidan yang sama seperti vitamin C.
