Abstract

Cardiotoxicity is one of the important side effects of doxorubicin, an anthracycline antibiotic and chemotherapeutic drug. The aim of this study was to explore the potential protective effect of andrographolide (Andro), an anti-inflammatory and anti-oxidant agents, against cardiotoxicity induced by doxorubicin (DXR). Thirty Sprague Dawley rats (80-100 g) were divided into four groups: (a) Control (b) DXR (4 mg/kg intraperitoneally (IP) were made weekly for 4 weeks), (c) DXR+Andro20 (low dose andro; 20 mg/kg IP weremade daily for 4 weeks, 24 h after DXR), (d) DXR+Andro100 (high dose andro; 100 mg/kg IP were made daily for 4 weeks, 24 h after DXR). Furthermore, at the end of experimental period, all rats were euthanized and hearts were removed for hispatological analyses. Hematoxylin-eosin (HE) and Masson Trichrome (MT) staining were used to observe the histomorphological alterations and fibrosis of hearts, respectively. Our results showed that andrographolide treatment (20 mg/kg) augmented the detrimental effects of DXR such as decreased body weight and heart weight, as compared with those in DXR-treated rats. Histopathologically, heart tissue from control group showed compact myocardial architecture without any noticeable lesions. Histopathological analysis fromDXR group showed severe inflammation and fibrosis, whereas DXR+Andro20 group showed almost normal heart morphology. Andrographolide at a dosage of 100 mg/kg did not show protective effects against doxorubicin,and even aggravated myocardial inflammation, as compared with DXR-treated rats. These results indicate that low dose of andrographolide compromised doxorubicin-induced decreased body weight, heart inflammation, andfibrosis.

Abstract

African Swine Fever (ASF) is a disease affecting pigs, caused by a double-stranded DNA virus that is not transmissible to humans or other animals. It leads to significant economic losses due to high morbidity and mortality rates, particularly in densely populated pig regions like Bali Province. During the ASF outbreak from June to December 2023, this study conducted histopathological research on clinical samples. Biological materials from twelve pigs confirmed positive for ASF via qPCR examination were histopathologically analyzed. Tissue samples from various organs underwent processing and examination using hematoxylin and eosin staining. Immunohistochemistry (IHC) was employed to detect the ASF virus’s p54 protein. Clinical symptoms, anatomical pathology, and histological examination revealed characteristic acute ASF lesions. Immunohistochemistry consistently showed p54 viral antigen distribution in mononuclear cells/macrophages across various organs, with the spleen and lymph nodes being dominant sites in 12 pigs (100%). This comprehensive study demonstrates the effectiveness of IHC in detecting the ASF virus and characterizing its histopathology.Keywords: ASF; histopathology; immunohistochemistry
