Background: Hepatotoxicity was one of the major side effects associated with doxorubicin treatment in cancer chemotherapy. The synthesized silver nanoparticles (AgNPs) from natural products such as algae especially green algae is one of the favorable means to minimize the deleterious effects of the chemotherapy. Thus, this study aimed to evaluate the preventive role of AgNPs synthesized by Ulva fasciata (U. fasciata) against doxorubicin-induced hepatotoxicity and oxidative stress in the liver of male Wistar rats.  Materials and Methods: In the present study, the green macroalga U. fasciata ethanolic extract was used as reducing agents to reduce Ag ions to Ag0. Doxorubicin-injected male Wistar rats were concomitantly treated with U. fasciata ethanolic extract and AgNPs synthesized by U. fasciata extract (AgNPs/U. fasciata) 3 times/week by oral gavage for 6 weeks. Results: The results showed that male Wistar rats injected with doxorubicin showed a significant increase in ALT, ALP and GGT activities and total bilirubin level as well as a reduction in the serum albumin level. The concurrent treatments of doxorubicin-injected rats with U. fasciata ethanolic extract and AgNPs/U. fasciata significantly abrogate these alterations. The altered levels of tumor biomarkers CA19.9 and AFP as well as pro-inflammatory cytokine, TNF-α, and anti-inflammatory cytokine, IL-4, in doxorubicin-injected animals were significantly ameliorated by concurrent treatment with U. fasciata and AgNPs/U. fasciata. Moreover, the elevated mRNA expression of p53 significantly decreased by treatment. In association, the doxorubicin-induced deleterious histological changes represented by severe hydropic degenerative changes, steatosis, inflammatory cell infiltration, Kupffer cell proliferation and apoptosis were remarkably improved by concurrent treatment with U. fasciata extract and AgNPs/U. fasciata which was more potent. Conclusion: Based on results of this study, it can be concluded that U. fasciata extract and AgNPs/U. fasciata counteracts doxorubicin-induced toxicity by suppression of inflammation, oxidative stress and apoptosis. AgNPs/U. fasciata was the most potent in improving hepatocyte integrity and liver histological architecture.  Graphical Abstract

Fractures are a serious health problem in Indonesia due to increasing prevalence. The healing process of fracture is disturbed by the oxidative stress that caused by imbalance quantity of free radical and antioxidant. An antioxidant such as polyphenol, which can be found in cocoa, is needed to suppress oxidative stress. The study aimed to investigate the effect of the ethanolic extract of cacao on fracture healing process in a rat model through MDA concentration and histopatological appearance. This study is in vivo experimental study with post-test only controlled group design. 30 male Wistar rats were randomized and divided into 5 groups. 1 group was rats without fractured. The negative control and three treatment groups were rats with fractured manually on left tibia under anesthesia and immobilized by bandage. The treatment groups treated with cocoa ethanolic extract in a dose of 125 mg/kgBW, 250 mg/kgBW, and 500 mg/kgBW orally for 21 days. The result showed that there was a significant different between the treatment groups and the negative control group on MDA concentration and histopatological appearance (p>0,05). The corelation between them were strong and had negative direction (R=-0,771). The study concluded that cocoa ethanolic extract had a positive effect to supress oxidation stress and increases the number of osteoblast on fracture healing process. Key words: cocoa ethanolic extract, polyphenol, fracture healing process, oxidative stress

Enhydra fluctuations an edible semi-aquatic vegetable plant are widely used in the traditional system of medicine. Ethanolic extract of Enhydra fluctuans was screened for analgesic & anti-inflammatory activity. Analgesic activity was evaluated by the hot plate method and anti-inflammatory activity was evaluated by formalin induce paw edema in Wistar rats (male). Ethanolic extract dose of 300 mg/kg reduce formalin induce paw inflammation and also increased the pain threshold in rats evidenced by hot plate method. The experimental results concluded that Enhydra fluctuans have significant analgesic and anti-inflammatory activity may due to flavonoid and phenolic compound content.

Syzygium campanulatum and Syzygium aromaticum contains antioxidant components suchas flavonoids, phenolic, and terpenoids. May have hepatoprotective properties in reducing SGPT and SGOT activity. This research wants to determine the potency of hepatoprotective of ethanolic extract of Syzygium campanulatum (Korth) and Syzygium aromaticum leaf compared with curcuma tablets. This research uses 24 male Wistar rats divided into 6 groups: I, II, III (as a normal, induction, and compared control), group IV, V, VI were treated 105, 210, and 420 mg/kg BW respectively. The study was conducted for 9 days. After 7 days of treatment, treated groups were exposed by hepatotoxic dose of paracetamol (2000 mg/kg BW). The SGPT and SGOT activity of all groups was measured by enzimatic assay. The result can be concluded that Syzygium campanulatum extract was found to be active as hepatoprotective agent with 210 mg/kg BW dosage (SGPT 21.76 ± 3.98 U/L and SGOT 7.32±6.74U/L) as eff ective as with the curcuma tablets (SGPT 23.91 ± 4.41 U/L and SGOT 14.12±5.37 U/L) and the hepatoprotective activity of Syzygium campanulatum extract at a dosage 420 mg/kg BW better than curcuma tablets (SGPT 12.43 ± 6.51 U/L and SGOT 6.64 ± 5.88 U/L).

Background: Growing evidence has shown that the apoptosis of cells plays an important role in the advancement of the Diabetic nephropathy (DN). Objectives: This study attempted to discover the therapeutic potential of Peganum harmala leaf extract in the apoptosis of diabetic kidney disease. Methods: In the present experimental research, 32 male Wistar rats were studied, and diabetes was induced by streptozotocin (STZ) (65 mg/kg). The animals were randomly divided into four groups (n=8, in each group) as follows: control, diabetic, control+leaf extract, diabetic+leaf extract. For our purposes, the methanolic extract of P. harmala leaves (150 mg/kg) was given by gavage for 28 days. Flow cytometry and real-time polymerase chain reaction (PCR) analyses were utilized to determine the percentages of apoptotic cells. Also, histological alterations and blood biochemical parameters were evaluated. Results: The P. harmala leaf extract has a high amount of flavonoids (25.84%), a lower percentage of alkaloids (0.14%), and some antioxidant properties. Serum urea (P<0.001) and apoptosis (P<0.05) significantly elevated in diabetic rats relative to the control ones. The mean of fasting blood creatinine, urea, and albumin level was not significantly changed in diabetic+leaf extract rats as compared to the diabetic ones. Histopathological results also displayed that diabetic complications in the kidney could not be improved following treatment by the leaf extract of P. harmala. In addition, the leaf extract could not significantly reduce the apoptosis and caspase-3 expression compared to diabetics in renal cells. Conclusion: Based on our findings, the leaf extract of P. harmala is unable to inhibit apoptosis in the diabetic kidney model.
