Abstract

Domestic chicken eggshells contain calcium and protein that could be useful in wound healing process. This research was conducted to determine whether domestic chicken eggshells can accelerate wound healing. Twenty one male Swiss-Webster mice  with 2 cm incision were divided into 3 groups. Negative control group were given Carboxymethyl cellulose 1% (CMC), positive control group were given feracrylum 1% (FER), and the eggshells group given domestic chicken eggshells powder (KT). Treatment and data mesurement was measured every day until  the 7th day. On the 7th  day the average length of the wound were analyzed and the skin tissue is taken for microscopic examination. Data analyzed using one-way ANOVA followed by Post Hoc Least Significant Difference (LSD) with p=0,05. On macroscopic examination, there were  highly significant differences between KT compared to CMC and highly significant differences between KT compared to FER. the average length of wound on the 7th day on KT 0,63 cm shorter than CMC 1,07 (p=0,000) and FER 0,81 cm (p=0,003). On microscopic examination, the degree of reepithelization on KT groups are severe, moderate for collagen density, fibroblasts density, subepithelial neutrophil density, degree of edema, and mild for angiogenesis. We conclude domestic chicken eggshells powder can accelerate wound healing. Key words: domestic chicken eggshells, incision wound, wound healing

Abstract

Background: Cardiac aging is closely associated with mitochondrial dysfunction and impaired quality control mechanism. Exercise has been shown to modulate mitochondrial homeostasis, however, its effects on cardiac mitophagy and mitochondrial dynamics during aging remain unclear. This study investigated the effects of moderate-intensity treadmill training on mitochondrial maintenance-related gene expression in the hearts of young and aged Wistar rats.Methods: Young and aged rats were divided into four groups: young control, young exercise, aged control, and aged exercise (n=6 per group). Exercise groups performed treadmill running at 20 m/min for 30 minutes/day, 5 days/week for 8 weeks. Cardiac gene expression levels of Pink1, Parkin, Mfn1, Mfn2, Opa1, Drp1, and Fis1 were analyzed using semi-quantitative polymerase chain reaction (PCR). Data were analyzed using one-way ANOVA or Kruskal–Wallis test followed by appropriate post hoc analyses.Results: Exercise significantly increased Mfn2 expression in aged exercise rats compared with aged controls (p=0.029), suggesting partial restoration of age-related decline. Expression of Mfn1 and Drp1 varied among groups but showed no significant pairwise differences. Expression levels of Opa1, Fis1, Pink1, and Parkin remained unchanged. These results indicate that moderate exercise selectively enhances mitochondrial fusion capacity while maintaining balanced fission and basal mitophagy activity.Conclusion: Moderate-intensity treadmill training promotes mitochondrial  fusion-related adaptation in aging cardiac tissue. Regular moderate exercise may represent a potential non-pharmacological strategy to support mitochondrial function and mitigate cardiovascular aging.
