The present study was undertaken to evaluate the cardioprotection potential and underlying molecular mechanism afforded by a selenium (Se) polysaccharide (Se-AVP) from Aloe vera in the ischemia-reperfusion (I/R) model of rats in vivo. Myocardial I/R injury was induced by occluding the left anterior descending coronary artery (LAD) for 30 min followed by 2-h continuous reperfusion. Pretreatment with Se-AVP (100, 200, and 400 mg/kg) attenuated myocardial damage, as evidenced by reduction of the infarct sizes, increase in serum and myocardial endogenous antioxidants (superoxide dismutase (SOD), glutathione peroxidase (GSH), and catalase (CAT)), and decrease in the malondialdehyde (MDA) level in the rats suffering I/R injury. This cardioprotective activity afforded by Se-AVP is further supported by the decreased levels of cardiac marker enzymes creatine kinase (CK) and lactate dehydrogenase (LDH), as well as the rise of myocardial Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities in I/R rats. Additionally, cardiomyocytic apoptosis was measured by terminal-deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) staining and the result showed that the percent of TUNEL-positive cells in myocardium of Se-AVP-treated groups was lower than I/R rats. In conclusion, we clearly demonstrated that Se-AVP had a protective effect against myocardial I/R injury in rats by augmenting endogenous antioxidants and protecting rat hearts from oxidative stress-induced myocardial apoptosis.

Background: Aloe vera is more effective than routine treatment alone to improve symptoms of phlebitis. However, few studies have been conducted in Indonesia to explore the effectiveness of aloe vera on phlebitis among hospitalized children with wide-ranged of age. The purpose of this study was to evaluate the effectiveness of aloe vera in reducing the degree of phlebitis among hospitalized children in Indonesia.Methods: This study was conducted using a quasi-experimental design, a pretest-posttest design with a control group. The sample of this study was 42 children (21 respondents in both groups) with phlebitis that hospitalized in one general public health in West Java, Indonesia from May to July 2019. The intervention group was provided a compress of extract aloe vera (5 ml) and the control group was provided a compress of 70% Alcohol. The instrument used in this study was Visual Infusion Phlebitis (VIP) score. The Mann Whitney test was used to evaluate the difference of degree of phlebitis between intervention and control group and Wilcoxon test used to evaluate the difference before and after the intervention.Results: The majority of respondents were in the infant stage (45.23%), having normal nutrition status (54.76%). On average, the length of stay in the hospital was seven days and receive intravenous therapy solution non-electrolyte and antibiotics. The average score for the post-test score was decreased in both classes. There is a statistically significant difference between the phlebitis score both in the Aloe Vera and 70% baseline-specific experimental classes, during 8, 16, 32, 40, 48 hours of treatment implementation (p

Background Aloe’s reported bioactivities (anticancer, anti-inflammatory and wound healing) suggest they might inhibit a subgroup of matrix metalloproteinases (MMPs) called gelatinases (MMP-2 and MMP-9). The goal of the present study was to compare the MMP inhibitory potential of two Aloe species, A. vera and A. arborescens. Methods Different types of extraction were tested and specific bioactive compounds were quantified. Cancer cell invasion inhibitory activities were measured in vitro using the wound healing assay in human colon cancer cells (HT29). Effects on gelatinase activities were further assessed by dye-quenched gelatin and gelatin zymography. Results Different types of extraction yielded significantly different levels of bioactivities and of bioactive compounds, which might be due to a greater amount of extractable bioactive compounds such as anthraquinones. Both A. arborescens and A. vera have potential as inhibitory agents in cancer cell proliferation via MMP-9 and MMP-2 enzymatic activity inhibition, being able to reduce colon cancer cell proliferation and migration but A. arborescens showed to be a more effective inhibitor of cancer cell migration than A. vera. Conclusion This work opens novel perspectives on the mode of action of Aloe species in cancer cell migration and may provide clues as to why there are so many conflicting results on Aloe’s activities.

A plethora of publications have reported several cytotoxic effects associated with chronic consumption of thermoxidized palm oil. This research aims to investigate the effects of garlic and Aloe vera on liver function and hepatic cytoarchitecture in rats fed thermoxidized palm oil diet.,Thirty-five male albino Wistar rats weighing 150-180 g were used for this study. They were randomly assigned into five groups (n = 7): control, thermoxidized palm oil diet fed (TPO), TPO plus garlic juice (TPO + G), TPO plus Aloe gel (TPO + A) and TPO plus garlic/Aloe gel (TPO + G + A). The TPO diet was prepared by mixing 15 g of cooled thermoxidized palm oil with 85 g of rat feed. The juice and gel were orally administered at doses of 2.00 ml/kg and 19.12 ml/kg, respectively. After 3 months of feeding and administration, the animals were sacrificed using standard methods and blood collected via cardiac puncture for analysis.,Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase were significantly increased (p < 0.001) in the TPO group compared to the control. This increase was reduced (p < 0.001) in all the treated groups compared to TPO, with the greatest decrease (p < 0.001) seen in TPO + A. Total bilirubin was increased (p < 0.001) in the TPO group compared to the control, whereas there was a significant decrease (p < 0.001) in all the treated groups. Serum proteins and plasma fibrinogen were lowered (p < 0.001) in the TPO group compared to the control but increased progressively in all the treated groups. TPO induced prominent histopathological derangements of the liver tissues. However, there were marked improvements following treatment with garlic and Aloe vera.,The results obtained in this study have revealed that chronic consumption of thermoxidized palm oil is hazardous to health by inducing hepatotoxicity, as seen in increased ALT, AST and total and unconjugated bilirubin and decreased total protein. However, these debilitating effects were seen to be greatly ameliorated following garlic juice and Aloe vera gel administration. If these results are to be extrapolated to humans, then the chronic consumption of thermoxidized palm oil diet should be seriously discouraged.

Aloe vera is a traditional wound‑healing medicine used for the treatment of skin disorders. Aloe polysaccharide (APS) is the main macromolecule of Aloe vera, which contributes to its function. Psoriasis is an immune‑mediated chronic inflammatory disease, which affects 2‑3% of the general population. The conventional remedies used to treat psoriasis demonstrate limited effects; therefore, natural products, including Aloe vera, are being taken into consideration. However, the effects of APS on the treatment of psoriasis and the underlying mechanisms remain to be elucidated. The human keratinocyte cell line HaCaT was used to determine the effects of APS on psoriasis. Cells were randomly divided into five groups: i) Negative control group; ii) tumor necrosis factor (TNF)‑α stimulated psoriasis model group; and iii) APS (20, 40 and 80 µg/ml) pretreated psoriasis groups. Cell viability and proliferation were investigated using the CCK‑8 assay. ELISA and western blotting were applied to study the abundance of interleukin (IL)‑8 and IL‑12 in TNF‑α‑incubated culture medium and APS‑treated HaCaT cells, respectively. In addition, the mRNA expression levels of p65, and the protein expression levels of nuclear factor (NF)‑κB inhibitor‑α (IκBα) and phosphorylated‑p65, were detected by reverse transcription‑quantitative polymerase chain reaction and western blotting, respectively. APS was revealed to significantly reduce TNF‑α‑stimulated elevation of HaCaT cell proliferation in a dose‑dependent manner. The expression levels of inflammatory factors, including IL‑8 and IL‑12, were increased in response to TNF‑α. In addition, the mRNA and protein expression levels of p65 were increased following treatment with TNF‑α. Notably, treatment with APS was demonstrated to significantly attenuate the aforementioned effects in a dose‑dependent manner. Furthermore, IκBα protein expression levels were significantly reduced following treatment with TNF‑α, which was significantly reversed following treatment with APS. In conclusion, these results suggested that APS inhibited TNF‑α‑induced proliferation of keratinocytes and overactivation of the NF‑κB signaling pathway.

Background: The prevalence of diabetes is rapidly rising worldwide at an alarming rate. Over the last 30 years, the status of diabetes has changed from being considered as a mild disorder of the elderly to one of the major causes of morbidity and mortality affecting the youth and middle aged people. Aloe vera has been used in folk medicine as a remedy for various diseases. It is extensively studied in treating diabetes mellitus. Aims and Objectives: This study evaluates the hypoglycemic effect of A. vera leaf dried powder and compares it with standard Metformin in alloxan-induced diabetic rats. Materials and Methods: Diabetes mellitus was experimentally induced in rats by intraperitoneal injection of alloxan monohydrate at a dose of 150 mg/kg. A pure extract of A. vera leaf was given orally once daily for 5 weeks in three graded doses of 100, 200, 400 mg/kg and compared with control (2 ml distilled water) and standard (metformin 50 mg/kg). Results: The elevated blood glucose levels in diabetic rats were reduced by the treatment with A. vera leaf extract at doses of 200 mg/kg and 400 mg/kg which was comparable to 50 mg/kg of metformin with no statistically significant difference (P < 0.0001). Conclusion: Our study concludes that A. vera leaf extract has a favorable effect in reversing alloxan induced hyperglycemia in rats.
