Liver Changes

The plant Solanum nudum has been used by the community of Tumaco (Nariño, Colombia) as a cure for malaria. Our group has confirmed the in vitro antimalarial activity against the strain of Plasmodium falciparum FCB-2. During our in vivo studies on the therapeutic effect of Solanum nudum extracts on mice infected with Plasmodium berghei, we observed yellowish tint in the palms of mice treated with the aqueous extract via ip at a concentration of 2.4% w/vol. This findings suggested the need to carry out a histology study of the liver. Plasmodium berghei infection produces liver changes such as the deposit of pigment inn sinusoids, leucocytes infiltration, esteatosis and necrosis of hepatocytes. These changes were also observed when the mice were treated with methane and hexane extracts from Solanum nudum; however necrosis of hepatocytes in mice infected with malaria decreased 47–65% when they were administered wither with queous extract, or tumacoside A and degraded diosgenone, compounds from methane and hexane extracts of Solanum nudum respectively.

Study Results

Background: Diabetes mellitus is major issue to public health as its prevalence is rising day by day. Synthetic agents available for the diabetic treatment are expensive or produce undesirable side effect on chronic use and some of them are not suitable during pregnancy. Herbal medicines accepted widely due to side effects and low cost. Objective: The aim of present study was to evaluate the activity of Withania coagulans extract using In-vitro and In-vivo model. Methods: Different three types of Withania coagulans extract were prepared using aqueous (W1), Alcohol (W2) and hydro-alcoholic (50:50) mixture (W3). In-vitro Anti-diabetic activity of the all three extracts evaluated using RINm5F Pancreatic beta cells.Further, n-vivo anti-diabetic evaluation performed by administering 50 mg/kg (p.o) aqueous extract for 7 days in Streptozotocin (STZ)-induced mice. Body weight of the animals was also determined to perform acute toxicity study. Results: The results of in –vitro cell based study indicated that among all three extract, aqueous extract (W1) of Withania coagulans showed potential increase in inulin release. The EC50 of the W1 (249.6 µg/L) which is compared with standard (Glibenclamide) EC50. From the results of In-vitro study, W1 subjected for acute toxicity study and the acute toxicity study results indicated LD50 of 50mg/kg. Diabetic rats treated with W1 extract at oral dose of 50 mg/kg for 7 days showed 34.17% reduction in blood glucose in comparison to untreated diabetic (STZ-induced) rats. Blood glucose levels of Standard treated (Glibenclamide) and control untreated. Conclusion: In conclusion, results of pancreatic beta cell based study showed increase in insulin release by administration of extract. Further aqueous extract (W1) was potentially reduced blood glucose level in STZ induced diabetic mice.

The use of insects as a feasible and useful natural product resource is a novel and promising option in alternative medicine. Several components from insects and their larvae have been found to inhibit molecular pathways in different stages of cancer. This study aimed to analyze the effect of aqueous and alcoholic extracts of Vespa orientalis larvae on breast cancer MCF7 cells and investigate the underlying mechanisms. Our results showed that individual treatment with 5% aqueous or alcoholic larval extract inhibited MCF7 proliferation but had no cytotoxic effect on normal Vero cells. The anticancer effect was mediated through (1) induction of apoptosis, as indicated by increased expression of apoptotic genes (Bax, caspase3, and p53) and decreased expression of the anti-apoptotic gene Bcl2; (2) suppression of intracellular reactive oxygen species; (3) elevation of antioxidant enzymes (CAT, SOD, and GPx) and upregulation of the antioxidant regulator Nrf2 and its downstream target HO-1; (4) inhibition of migration as revealed by in vitro wound healing assay and downregulation of the migration-related gene MMP9 and upregulation of the anti-migratory gene TIMP1; and (5) downregulation of inflammation-related genes (NFκB and IL8). The aqueous extract exhibited the best anticancer effect with higher antioxidant activities but lower anti-inflammatory properties than the alcoholic extract. HPLC analysis revealed the presence of several flavonoids and phenolic compounds with highest concentrations for resveratrol and naringenin in aqueous extract and rosmarinic acid in alcoholic extract. This is the first report to explain the intracellular pathway by which flavonoids and phenolic compounds-rich extracts of Vespa orientalis larvae could induce MCF7 cell viability loss through the initiation of apoptosis, activation of antioxidants, and inhibition of migration and inflammation. Therefore, these extracts could be used as adjuvants for anticancer drugs and as antioxidant and anti-inflammatory agents.

Anastatica hierochuntica L. ( A. hierochuntica), a folk medicinal plant, was evaluated for mutagenic potential via in vitro and in vivo assays. The in vitro assay was conducted according to modified Ames test, while the in vivo study was performed according to Organisation for Economic Co-operation and Development guideline for mammalian erythrocyte micronucleus assay. Four groups ( n= 5 males and 5 females per group) Sprague Dawley rats were randomly chosen as the negative control, positive control (received a single intramuscular injection of cyclophosphamide 50 mg/kg), 1000 and, 2000 mg/kg A. hierochuntica aqueous extracts. All groups except the positive control were treated orally for three days. Findings of the in vitro assay showed mutagenic potential of AHAE at 0.04 and 0.2 mg/ml. However, no mutagenic effect was demonstrated in the in vivo study up to 2000 mg/kg. No significant reduction in the polychromatic and normochromatic erythrocytes ratio was noted in any of the groups. Meanwhile, high micronucleated polychromatic erythrocytes frequency was seen in cyclophosphamide-treated group only. These findings could perhaps be due to insufficient dosage of A. hierochuntica aqueous extracts to cause genetic damage on the bone marrow target cells. Further acute and chronic in vivo toxicity studies may be required to draw pertinent conclusion on the safety aspect of A. hierochuntica aqueous extracts consumption. Impact statement In this paper, we report on the mutagenicity evaluation of Anastatica hierochuntica aqueous extract. This is a significant research in view of the popularity of this herb consumption by the people across the globe despite of limited scientific evidence on its toxicity potential. This study is intended to encourage more extensive related research in order to provide sufficient evidence and guidance for determining its safe dosage.
