Abstract

Aim: This research aimed to evaluate the effects of pomegranate extract standardized to 40% ellagic acid on the incised wound in albino rats.

Materials and Methods: Fifty albino rats were divided into 10 treatment groups. The five groups were sacrificed on the 8^th day, while the others were sacrificed on the 15^th day. Two groups of albino rats with incised wound were not treated at all (P0), the other two groups of albino rats with incised wound were treated with Betadine® (P1) ointment, and the rest of the groups were treated with pomegranate extract standardized to 40% ellagic acid with a concentration of 2.5% (P2), 5% (P3), and 7.5% (P4). The treatments were carried out twice a day with an interval of 12 h for 7 and 14 days. At the end of the research, the skin tissue of those albino rats had been taken for histopathologic preparations before H and E staining was performed.

Results: Collagen deposition, polymorphonuclear neutrophils (PMN) infiltration, angiogenesis, and fibrosis degree in Group P4 treated with 7.5% pomegranate extract standardized to 40% ellagic acid for 14 days were significantly different from those in Groups P0, P1, P2, and P3, especially in the case of PMN inflammation (p<0.05).

Conclusion: The administration of 7.5% pomegranate extract standardized to 40% ellagic acid for 14 days on incised wounds of those albino rats can accelerate the wound healing process characterized by collagen deposition improvement, PMN infiltration in the wound area, angiogenesis, and fibrosis degree.

Abstract

Aim: The objective of this research was to study and to prove the effectiveness of hyperbaric oxygen therapy (HBOT) starting time on liver morphofunctional changes after ischemia-reperfusion in the hind limb of rabbits.
Materials and Methods: This research used a complete randomized design with 4 groups and 6 repetitions on each. After 6 h artery femoral is ligation, reperfusion was performed for 100 min (G1), HBOT for 90 min after 10 min reperfusion (G2), 10 min reperfusion (G3), and HBOT 90 min after 60 min reperfusion (G4). Then, all of the rabbits were sacrificed. The liver and blood were taken for histopathological changes examination as well as for measuring the level of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The statistical test using Kruskal-Wallis and Mann-Whitney showed that the score of degeneration, necrosis, and portal inflammation in groups without HBOT (G1 and G3) were not significantly different, as well as in group with HBOT (G2 and G4) (p>0.05). However, the scores of histopathological changes in G1 and G3 were significantly different from those in G2 and G4 (p<0.05). The levels of AST and ALT in the groups without hyperbaric therapy (G1 and G3) were not significantly different from those in the groups treated with hyperbaric therapy (G2 and G4) (p>0.05).
Results: Hind limb ischemia injury reperfusion can trigger damage for liver morphology, but not lead to liver dysfunction. Reperfusion can trigger increased activity of neutrophils, while neutrophil infiltration in the organ will lead to dysfunction. HBOT can inhibit the activity of neutrophils and the dysfunction of organs caused by ischemic reperfusion.
Conclusion: HBOT for 90 min, both 10 and 60 min after the reperfusion, can protect hepatocytes from damage.

Abstract

Aim: Skin burn is a health problem that requires fast and accurate treatment. If not well-treated, the burn will cause various damaging conditions for the patient. The leaf extract of Madeira vine (Anredera cordifolia (Ten.) Steenis), or popularly known as Binahong in Indonesia, has been used to treat various diseases. The purpose of this research is to determine the effects of leaf extracts of Madeira vine (A. cordifolia (Ten.) Steenis) on skin burn healing process in rats as an animal model.

Materials and Methods: In this research, there were four treatment groups: G0, G1, G2, and G3, each consisting of five rats. All these rats were given skin burns, using hot metal plates. Then, sulfadiazine was given to G0, 2.5% leaf extract of Madeira vine was given to G1, 5% extract was given to G2, and 10% extract was given to G3, for straight 14 days topically, 3 times a day. At the end of the treatment period, skin excisions were conducted, and histopathological examination was carried out.

Result: Microscopic observation on the wound healing process on the collagen deposition, polymorphonuclear infiltration, angiogenesis, and fibrosis showed that G2 had a significant difference with G0, G1, and G3 (p<0.05), while group G0 was significantly different from G1 and G3 (p<0.05). The better burn healing process on G2 allegedly because of the activity of flavonoid, saponin, and tannin, contained in the Madeira vine, which have the antioxidant, anti-inflammatory, and antibacterial effects.

Conclusion: The ointment from the 5% leaf extract of Madeira vine (A. cordifolia (Ten.) Steenis) has been proven to be effective to be used for topical burn therapy.
