RESUMO

OBJECTIVE: Jatropha mollissima is one of the most valuable medicinal plants used for the treatment of hepatic disorders. It is evident that 500 mg/kg of sodium valproate causes the hepatotoxicity, ototoxicity, gastrotoxicity, bone marrow suppression, and inflammation. This study was designed to explore the medicinal uses of Jatropha mollissima in hepatic disorders. METHODS: Hepatotoxicity was induced in Wister albino rats by injecting sodium valproate at the rate of 500 mg/kg once daily for fourteen days. Six male rats, each weighing 220-270 g, were placed into four separate groups for the study. The first group was treated with normal saline. Treatment of the second group was carried out by SVP for four days consecutively together with saline for three weeks. Group three and four were treated with sodium valproate and Jm hydroalcoholic extract applied in the concentrations of the 200 mg/kg and 400 mg/kg for the period of the three weeks. Phytochemical screening and HPLC analysis were conducted to identify the phytochemical nature and polyphenols in extract, respectively. DPPH, SOD, and NO tests were performed to measure the antioxidant activity. RESULTS: With the initial dose of treatments to rats, anatomic, physiological, or histopathologic abnormalities were detected. After three weeks, extract of Jatropha mollissima was used to treat the valproic acid-induced hepatotoxicity (P < 0.05). CONCLUSION: It was concluded that sodium valproate (SVP) and Jm extract were administered together. The hepatoprotective effects were extraordinarily high, with high concentrations of 400 mg/kg.

RESUMO

Murraya koenigii (Mk) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. The excessive use of cisplatin (Cis> 50 mg/m2) is associated with nephrotoxicity, ototoxicity, gastrotoxicity, myelosuppression, and allergic reactions. Remedial measures are needed for the protection of nephrotoxicity against cisplatin. Thus, we have investigated Mk leaf extract's nephroprotective effects to prevent cisplatin-induced nephrotoxicity in Wistar albino rats. The presence of polyphenols, phenolic compounds, tannins, and saponins was revealed during phytochemical investigation, and antioxidant activity was recorded. There were no toxicological symptoms in the treated rats, and no anatomical, physiological, or histological abnormalities were found compared to the control rats. The results of correcting cisplatin-induced nephrotoxicity revealed that the extract has a significant ability to treat kidney damage, with most parameters returning to normal after only three weeks of therapy. It was concluded that co-administered cisplatin with Mk leaves extract showed exceptional nephroprotective effects at a 400 mg/kg dose ratein Cis-induced nephrotoxicity.

RESUMO

In recent years, pH-sensitive hydrogels have been developed for the delivery of therapeutic agents to specific target sites that have a defined pH range. The use of pH-responsive polymers in hydrogels allows drug delivery to the desired pH range of the target organ. The primary aim is to increase the retention time of the drug in the small intestine by utilizing the swelling mechanism of the hydrogel at intestinal pH. In this study, polyethylene glycol (PEG) was used as a polymer to formulate a pH-sensitive hydrogel of Ezetimibe to deliver the drug to the small intestine where it inhibits the absorption of cholesterol. Design Expert software was applied to design and optimize the trial formulations in order to obtain an optimized formulation that has all the desired characteristics of the hydrogels. The PEG/Acrylic Acid hydrogels showed the maximum swelling at pH 6.8, which is consistent with the pH of the small intestine (pH 6-7.4). The maximum entrapment efficiency of the hydrogels was 99%. The hydrogel released 80-90% of the drug within 24 h and followed first-order release kinetics, which showed that the release from the drug was sustained. Hence, the results showed that the choice of a suitable polymer can lead to the development of an efficient drug-loaded hydrogel that can deliver the drug at the specific pH of the target organ.

RESUMO

BACKGROUND AND PURPOSE: Despite many liver disorders, clinically useful drugs are scarce. Moreover, the available therapies are facing the challenges of efficacy and safety. Alhagi camelorum has been used in folk medicine globally for millennia to treat several ailments. Alhagi camelorum (Ac) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. Our goal was to determine the hepatoprotective activity of Alhagi camelorum against valproic acid induced hepatotoxicity using an animal model. EXPERIMENTAL APPROACH: The animals were segregated in 4-groups (6 male rats each) weighing 250-290 g. Group-1 animals were treated with normal saline, Group-2 animals were treated with VPA at the dose of 500 mg/kg i.p for 14 days consecutively, while Group-3 and 4 were treated with valproic acid (VPA) at the dose of 500 mg/kg i.p for 14 days along with 400 mg/kg and 600 mg/kg of Ac hydroalcoholic extract respectively. Subsequently, blood serum samples and liver tissues were collected for biochemical and histopathological analysis. Phytochemical screening was carried out to screen for phytochemical classes and HPLC analysis was conducted to screen polyphenols. The antioxidant activity was carried by different assays such as DPPH, SOD, NO etc. KEY RESULTS: The administration of Ac showed hepatoprotection at the doses of 400 and 600 mg/kg. Ac significantly reduces the elevated serum levels of liver biomarkers compared to the valproic acid-induced hepatotoxic group. These findings were confirmed with histopathological changes where Ac was capable of reversing the toxic effects of valproic acid on liver cells CONCLUSION: It is concluded that Ac showed significant hepatoprotective effects at different doses in the animal model used in this study.

RESUMO

Alhagi camelorum (AC) is an old plant with a significant therapeutic value throughout Africa, Asia, and Latin America. The overuse of cisplatin (Cis > 50 mg/m2) is associated with observed nephrotoxicity, ototoxicity, gastrotoxicity, myelosuppression, and allergic reactions. Remedial measures are needed for the protection of nephrotoxicity against cisplatin. Thus, we investigated the nephroprotective effects of AC plant extract to prevent cisplatin-induced nephrotoxicity in albino Wistar rats. The presence of polyphenols, phenolic compounds, tannins, and saponins was revealed during phytochemical investigation, and a significantly intense antioxidant activity was recorded. There were no toxicological symptoms in the treated rats, and no anatomical, physiological, or histological abnormalities were found compared to the control rats. The results of correcting cisplatin-induced nephrotoxicity revealed that the extract has a significant ability to treat kidney damage, with most parameters returning to normal after only three weeks of therapy. It is concluded that co-administration of cisplatin with AC extract showed exceptional nephroprotective effects at a dose of 600 mg/kg for Cis-induced nephrotoxicity.

RESUMO

Non-Alcoholic Fatty Liver Disease (NAFLD) is characterized by the accumulation of fats in the liver. Relatively benign NAFLD often progresses to fibrosis, cirrhosis, and liver malignancies. Although NAFLD precedes fibrosis, continuous lipid overload keeps fueling fibrosis and the process of disease progression remains unhindered. It is well known that TGF-ß1 plays its part in liver fibrosis, yet its effects on liver lipid overload remain unknown. As TGF-ß1 signaling has been increasingly attempted to manage liver fibrosis, its actions on the primary suspect (NAFLD) are easily ignored. The complex interaction of inflammatory stress and lipid accumulation aided by mediators scuh as pro-inflammatory interleukins and TGF-ß1 forms the basis of NAFLD progression. Anticipatorily, the inhibition of TGF-ß1 signaling during anti-fibrotic treatment should reverse the NAFLD though the data remain scattered on this subject to date. TGF-ß1 signaling pathway is an important drug target in liver fibrosis and abundant literature is available on it, but its direct effects on NAFLD are rarely studied. This review aims to cover the pathogenesis of NAFLD focusing on the role of the TGF-ß1 in the disease progression, especially in the backdrop of liver fibrosis.

RESUMO

Given the substantial benefits of grape seed extract (GSE) in reducing oxidative stress, the study aimed development, characterization and comparative analysis of GSE-based formulations. The development entailed extraction of GSE from Vitisvinifera L. HPLC confirmed catechin, epicatechin, gallic acid, epicatechingallate and procyanidin dimers. Storage of Formulations observed, Stability & rheological parameters determined. Olive oil used as a permeability enhancer. Presence of the highest oleic acid content (65-86%) in Olive oil, skin permeability within the stratum corneum was enhanced hence better transdermal skin absorption. Using two-way ANOVA, and T-test, efficacy of formulations and impact on slowing down skin aging by countering exogenous factors of oxidative stress determined. Non-invasive biophysical technique showed emulgel substantially reduced roughness, scaliness, winkles, and sebum content by 55%, 26%, 23.9% and 30.3% respectively enhancing elasticity and hydration by 50% and 32.2% respectively. Emulsion reduced roughness, scaliness, winkles and sebum content 14%, 13%, 21% and 26.13% respectively enhancing elasticity and hydration 45.3% and 29.85% respectively. The formulations significantly offset exogenous factors of aging and impact on free radicals and oxidative stress and may be safe to incorporate bio-active botanical antioxidants for evaluation of derma cosmetic benefits in management of dehydrated and aged facial skin.
