Objectives: Liver diseases are among the health challenges facing many people and health care providers worldwide. In their search for solution to these problems, researchers are increasingly advocating the use of herbal preparations with proven efficacy in protecting against hepatic disorders. They also investigate medicinal plants with the aim of developing new drugs.  Russelia equisetiformis is a plant which contains phytoconstituents that were reported to have biological activities, such as anti-inflammatory, antidiabetic, and membrane-stabilizing properties. In this study, the effect of methanol extract of R. equisetiformis (MEREQ) on paracetamol-induced hepatotoxicity was investigated in rats. Method: Rats were pretreated orally with graded doses (100 – 400 mg/kg b.w) of MEREQ for 7 days. On the 8th day, hepatotoxicity was induced in the pretreated rats with a single intraperitoneal injection of paracetamol (2 g/kg b.w). Rats were sacrificed on the 15th day; blood samples were taken for biochemical analysis, and the liver was excised for histopathological study. Biochemical parameters analyzed are alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total protein, albumin, and bilirubin. Results: Administration of paracetamol in the rats resulted in significant increase (p<0.05) in the serum levels of AST, ALT, ALP, and bilirubin compared with the control. Treatment with MEREQ significantly reduced (p<0.05) the levels of these parameters in a dose-dependent manner, compared with the untreated rats. No significant changes were observed in the serum levels total protein and albumin. Histopathological examination showed that administration of paracetamol caused distortions in the architecture of the liver, but the degree of degeneration of hepatocytes was reduced in the MEREQ-treated rats. Conclusion: From the results obtained in this study, it is concluded that methanol extract of R. equisetiformis has protective effect on paracetamol-induced hepatic injury.                                 Peer Review History: Received 8 November  2020; Revised 14 Decembe; Accepted 3 January, Available online 15 January 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

Introduction: Autism Spectrum Disorders (ASD) are among the severe developmental disorders, but have no specific treatments available. Ginkgo biloba (GK) has been reported to affect the neurotransmitter system and have anti-oxidant and anti-inflammatory properties that could impact the pathogenesis of valproic acid-induced autistic features. Aim: To identify the neuromodulatory effects of Ginkgo biloba extract on ASD induced by valproic acid in mice. Materials and Methods: A total of 24 male Wistar albino mice, 14-day-old, were used and divided into four groups (6 mice/group): Control, Ginkgo biloba extract-treated group {received GK at a dose 100 mg/kg via intraperitoneal injection once daily from Postnatal Day (PND) 13 to PND 40}, Valproic acid-treated group (VPA) (received Sodium Valproate at a dose 400 mg/kg via subcutaneous injection once on PND14), and Valproic acid + Ginkgo biloba extract-treated group (received VPA on PND14 and GK from PND 13 to PND 40). Neuro-behaviour tests (Open field, Social approach (three-chamber) test and T-maze spontaneous alternation) of mice were assessed. Biochemical tests (brain tissue malondialdehyde (MDA), Glutathione (GSH), Interleukin-6 (IL-6), Transforming Growth Factor-Beta (TGF-β1) and serum interleukin-17 (IL-17) were done. Also, histopathological, immunohistochemical and morphometric studies for the cerebellum were done. Analysis of Variances (ANOVA) was used for statistical analysis of the different groups followed by a post-hoc Tukey test. Results: VPA showed significant neuro-behavioural changes with a significant increase of (MDA, IL-6 and IL-17) and a significant decrease in (GSH and TGF-β1). Histopathological results revealed widespread neuronal affection, specifically of the Purkinje Cells (PCs) layer with a significant decrease in the expression of Myelin Basic Protein (MBP) and Serotonin. Ginkgo biloba ameliorated significantly VPA-induced autistic changes. Conclusion: Ginkgo biloba extract can ameliorate the autistic changes in mice through its anti-inflammatory and anti-oxidant activities in addition to its ability to modulate serotonin and MBP expression. It can be concluded that GK can be used as a potential disease-modifying treatment for Autism.

SummaryThe effect of alfa-tocopherol on the cell-cell interactions at the vessel wall were studied, using an in vitro model of human umbilical vein endothelial cell cultures (HUEC). Immune triggered granulocytes (PMN) will adhere to and damage HUEC and platelets enhance this PMN mediated endothelial injury. When HUEC are cultured in the presence of vitamin E, 51Cr-leakage induced by complement stimulated PMN is significantly decreased and the enhanced cytotoxicity by platelets is completely abolished (p <0.001).The inhibition of PMN induced endothelial injury is directly correlated to a diminished adherence of PMN to vitamin E- cultured HUEC (p <0.001), which may be mediated by an increase of both basal and stimulated endogenous prostacyclin (PGI2) from alfa-tocopherol-treated HUEC (p <0.025). The vitamin E-effect is abolished by incubation of HUEC with the irreversible cyclo-oxygenase inhibitor, acetylsalicylic acid, but the addition of exogenous PGI2 could not reproduce the vitamin E-mediated effects.We conclude that vitamin E exerts a protective effect on immune triggered endothelial damage, partly by increasing the endogenous anti-oxidant potential, partly by modulating intrinsic endothelial prostaglandin production. The failure to reproduce vitamin E-protection by exogenously added PGI2 may suggest additional, not yet elucidated vitamin E-effects on endothelial metabolism.

Background: Gentiana lutea (GL), commonly known as yellow gentian, bitter root, and bitterwort, belongs to family Gentianaceae. GL belongs to genus Gentiana, which is a rich natural source of iridoids, secoiridoids, xantones, flavonoids, triterpenoids, and carbohydrates. Medicinal plants from Gentiana species have anti-oxidant, anti-inflammatory, anti-mitogenic, anti-proliferative, and lipid-lowering effects, as well as a cardioprotective, hypotensive, vasodilator and anti-platelet activities. Objective: We reviewed the recent literature related to the effects of Gentiana species, and their active components on vascular diseases. Methods: Data used for this review were obtained by searching the electronic database [PUBMED/MEDLINE 1973 - February 2020]. The primary data search terms of interest were: Gentiana lutea, Gentienacea family, phytochemistry, vascular diseases, treatment of vascular diseases, anti-oxidant, anti-inflammatory, anti-atherogenic. Conclusion: Gentiana species and their constituents affect many different factors related to vascular disease development and progression. Therefore, Gentiana-based therapeutics represent potentially useful drugs for the management of vascular diseases.
