Phytochemical screening, antioxidant, immunomodulatory and analgesic potential of aqueous-ethanolic extracts of Euphorbia prostrata ait. and Crotalaria burhia Buch-Ham.

Euphorbia prostrata (E. prostrata) and Crotalaria burhia (C. burhia) are widely found in flora of the Cholistan Desert of Bahawalpur, Pakistan and are traditionally used to treat pain and chronic disease. The current study aimed to evaluate their phytochemical screening, antioxidant activity, in-vivo phagocytic activity, and analgesic activity. Both the plant extracts were investigated for phytochemical screening, Fourier Transform Infrared (FTIR) analysis, in-vitro antioxidant by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) method, in-vivo immunomodulatory activity by macrophages phagocytosis using carbon clearance rate assay and analgesic activity by acetic acid produced writhing method. Phytochemical screening showed the presence of carbohydrates, saponins, tannins, phenols, quinines, proteins, terpenes, glycosides, and alkaloids. FTIR analysis revealed the existence of different functional groups in both extracts. The DPPH method showed that E. prostrata exhibited a high antioxidant potential with an IC50 of 62.5 µg/ml whereas C. burhia showed a lower antioxidant potential. At the dose of 200 mg/kg body weight (b. wt), both the extracts showed a significant increase in the phagocytic index by 5.2 ± 0.2, and, 4.8 ± 0.1 (p < 0.001) respectively which was close to the 100 mg/kg b. wt of the standard drug (Levamisole) 5.4 ± 0.2. Both the extracts at the dose of 200 mg/kg b. wt also significantly reduced the writhing (abdominal contractions) count by 13.7 ± 0.3 and, 25.3 ± 1.5 (p < 0.001), showing 71.8% and 47.6% of reduced analgesic activity compared to the standard drug dicloran (diclofenac sodium), respectively. In conclusion, extracts of both plants indicate their role in the management of various disorders to relieve pain and modulate the immune system.

Electrochemical Methodologies for Investigating the Antioxidant Potential of Plant and Fruit Extracts: A Review.

In recent years, the growing research interests in the applications of plant and fruit extracts (synthetic/stabilization materials for the nanomaterials, medicinal applications, functional foods, and nutraceuticals) have led to the development of new analytical techniques to be utilized for identifying numerous properties of these extracts. One of the main properties essential for the applicability of these plant extracts is the antioxidant capacity (AOC) that is conventionally determined by spectrophotometric techniques. Nowadays, electrochemical methodologies are emerging as alternative tools for quantifying this particular property of the extract. These methodologies address numerous drawbacks of the conventional spectroscopic approach, such as the utilization of expensive and hazardous solvents, extensive sample pre-treatment requirements, long reaction times, low sensitivity, etc. The electrochemical methodologies discussed in this review include cyclic voltammetry (CV), square wave voltammetry (SWV), differential pulse voltammetry (DPV), and chronoamperometry (CAP). This review presents a critical comparison between both the conventional and electrochemical approaches for the quantification of the parameter of AOC and discusses the numerous applications of the obtained bioextracts based on the AOC parameter.

Astaxanthin, a Marine Carotenoid, Maintains the Tolerance and Integrity of Adipose Tissue and Contributes to Its Healthy Functions.

Recently, obesity-induced insulin resistance, type 2 diabetes, and cardiovascular disease have become major social problems. We have previously shown that Astaxanthin (AX), which is a natural antioxidant, significantly ameliorates obesity-induced glucose intolerance and insulin resistance. It is well known that AX is a strong lipophilic antioxidant and has been shown to be beneficial for acute inflammation. However, the actual effects of AX on chronic inflammation in adipose tissue (AT) remain unclear. To observe the effects of AX on AT functions in obese mice, we fed six-week-old male C57BL/6J on high-fat-diet (HFD) supplemented with or without 0.02% of AX for 24 weeks. We determined the effect of AX at 10 and 24 weeks of HFD with or without AX on various parameters including insulin sensitivity, glucose tolerance, inflammation, and mitochondrial function in AT. We found that AX significantly reduced oxidative stress and macrophage infiltration into AT, as well as maintaining healthy AT function. Furthermore, AX prevented pathological AT remodeling probably caused by hypoxia in AT. Collectively, AX treatment exerted anti-inflammatory effects via its antioxidant activity in AT, maintained the vascular structure of AT and preserved the stem cells and progenitor's niche, and enhanced anti-inflammatory hypoxia induction factor-2α-dominant hypoxic response. Through these mechanisms of action, it prevented the pathological remodeling of AT and maintained its integrity.

Development of herbal formulation of medicinal plants and determination of its antihyperuricemic potential in vitro and in vivo rat's model.

Hyperuricemia is a common metabolic disorder and several herbal formulations are being used for its treatment. The study aimed to develop herbal formulation (Urinil B) and find its hypouricemic effects in vitro and in vivo. Urinil B was prepared by taking Trachyspermum ammi, Piper nigrum and Berberis vulgaris equally. In vitro Dissolution test and xanthine oxidase inhibition assay was performed for checking capsule absorbance and IC50 calculation respectively. For in vivo experimentation, the study comprised of 14 groups of rats (n=6). Results showed that significant xanthine oxidase inhibition was shown by herbal formulation with IC50 of 586±1.5µg/mL. Oral administration of Urinil B 250, 500 and 1000 mg/kg decreased serum and liver uric acid levels of hyperuricemic rats in dose and time dependent manner. 3 day and seven day administration of Urinil B reduced serum and liver uric acid level more significantly as compared to one day administration. However, allopurinol normalized serum and liver uric acid levels in all study groups. The present study indicated marked hypouricemic effects of Urinil B in hyperuricemia induced by potassium oxonate in rats. However, due to caveat of small sample size in this study, clear conclusion regarding hypouricemic potential of Urinil B can't be made.

Bofutsushosan improves gut barrier function with a bloom of Akkermansia muciniphila and improves glucose metabolism in mice with diet-induced obesity.

Obesity and insulin resistance are associated with dysbiosis of the gut microbiota and impaired intestinal barrier function. Herein, we report that Bofutsushosan (BFT), a Japanese herbal medicine, Kampo, which has been clinically used for constipation in Asian countries, ameliorates glucose metabolism in mice with diet-induced obesity. A 16S rRNA sequence analysis of fecal samples showed that BFT dramatically increased the relative abundance of Verrucomicrobia, which was mainly associated with a bloom of Akkermansia muciniphila (AKK). BFT decreased the gut permeability as assessed by FITC-dextran gavage assay, associated with increased expression of tight-junction related protein, claudin-1, in the colon. The BFT treatment group also showed significant decreases of the plasma endotoxin level and expression of the hepatic lipopolysaccharide-binding protein. Antibiotic treatment abrogated the metabolic effects of BFT. Moreover, many of these changes could be reproduced when the cecal contents of BFT-treated donors were transferred to antibiotic-pretreated high fat diet-fed mice. These data demonstrate that BFT modifies the gut microbiota with an increase in AKK, which may contribute to improving gut barrier function and preventing metabolic endotoxemia, leading to attenuation of diet-induced inflammation and glucose intolerance. Understanding the interaction between a medicine and the gut microbiota may provide insights into new pharmacological targets to improve glucose metabolism.

Astaxanthin stimulates mitochondrial biogenesis in insulin resistant muscle via activation of AMPK pathway.

BACKGROUND: Skeletal muscle is mainly responsible for insulin-stimulated glucose disposal. Dysfunction in skeletal muscle metabolism especially during obesity contributes to the insulin resistance. Astaxanthin (AX), a natural antioxidant, has been shown to ameliorate hepatic insulin resistance in obese mice. However, its effects in skeletal muscle are poorly understood. The current study aimed to investigate the molecular target of AX in ameliorating skeletal muscle insulin resistance. METHODS: We fed 6-week-old male C57BL/6J mice with normal chow (NC) or NC supplemented with AX (NC+AX) and high-fat-diet (HFD) or HFD supplemented with AX for 24 weeks. We determined the effect of AX on various parameters including insulin sensitivity, glucose uptake, inflammation, kinase signaling, gene expression, and mitochondrial function in muscle. We also determined energy metabolism in intact C2C12 cells treated with AX using the Seahorse XFe96 Extracellular Flux Analyzer and assessed the effect of AX on mitochondrial oxidative phosphorylation and mitochondrial biogenesis. RESULTS: AX-treated HFD mice showed improved metabolic status with significant reduction in blood glucose, serum total triglycerides, and cholesterol (p< 0.05). AX-treated HFD mice also showed improved glucose metabolism by enhancing glucose incorporation into peripheral target tissues, such as the skeletal muscle, rather than by suppressing gluconeogenesis in the liver as shown by hyperinsulinemic-euglycemic clamp study. AX activated AMPK in the skeletal muscle of the HFD mice and upregulated the expressions of transcriptional factors and coactivator, thereby inducing mitochondrial remodeling, including increased mitochondrial oxidative phosphorylation component and free fatty acid metabolism. We also assessed the effects of AX on mitochondrial biogenesis in the siRNA-mediated AMPK-depleted C2C12 cells and showed that the effect of AX was lost in the genetically AMPK-depleted C2C12 cells. Collectively, AX treatment (i) significantly ameliorated insulin resistance and glucose intolerance through regulation of AMPK activation in the muscle, (ii) stimulated mitochondrial biogenesis in the muscle, (iii) enhanced exercise tolerance and exercise-induced fatty acid metabolism, and (iv) exerted antiinflammatory effects via its antioxidant activity in adipose tissue. CONCLUSIONS: We concluded that AX treatment stimulated mitochondrial biogenesis and significantly ameliorated insulin resistance through activation of AMPK pathway in the skeletal muscle.

Effects of medicinal plants on Alzheimer's disease and memory deficits.

Alzheimer's disease is an age-related neurodegenerative disorder characterized by memory deficits. Various studies have been carried out to find therapeutic approaches for Alzheimer's disease. However, the proper treatment option is still not available. There is no cure for Alzheimer's disease, but symptomatic treatment may improve the memory and other dementia related problems. Traditional medicine is practiced worldwide as memory enhancer since ancient times. Natural therapy including herbs and medicinal plants has been used in the treatment of memory deficits such as dementia, amnesia, as well as Alzheimer's disease since a long time. Medicinal plants have been used in different systems of medicine, particularly Unani system of medicines and exhibited their powerful roles in the management and cure of memory disorders. Most of herbs and plants have been chemically evaluated and their efficacy has also been proven in clinical trials. However, the underlying mechanisms of actions are still on the way. In this paper, we have reviewed the role of different medicinal plants that play an important role in the treatment of Alzheimer's disease and memory deficits using conventional herbal therapy.

Review: Comprehensive review on treatment of HIV.

HIV or AIDS is a major threat for humanity in the world especially in developing countries. The causative factor of the syndrome is HIV, which infects and destroys one of the cellular components of the immune system, the T cells, causing deficiency in the immunological surveillance and ultimately leading to AIDS. According to WHO, around 35 million people were living with HIV in 2013 and since the start of epidemic 39 million people have died due to AIDS. Center for disease control and prevention estimated in 2014 that 1,201,100 people aged 13 and above were suffering from HIV infection Worldwide. The most effective approach is the highly active antiretroviral therapy (HAART) containing the combined use of drugs having different mechanisms of action. However, complete eradication of HIV from the body does not occur by HAART, but it lead to long term toxicity occurs and emerges as drug resistant. Despite the recent development of various new antiretroviral compounds, there is still a need to develop need to search for new alternatives which are equally efficient and less expensive as compared to the contemporary treatment available. This review provides an overview and a summary of herbal medicines for HIV infection and summarized the efficacy and medicinal use of different plants used in the treatment of HIV infection. The objective of this review is to enlighten the recent advances in the exploration of medicinal plants used for treatment of HIV/AIDS.

Ways to manage hepatitis C without cirrhosis: Treatment by comparison of coded eastern medicine hepcinal with interferon alpha 2b and ribavirin.

Hepatitis C virus (HCV) infection is a serious and significant global health problem in the Pakistan and elsewhere. In majority of cases HCV infection remains asymptomatic but in advance cases it may progress to fibrosis of liver, shrinkage of liver cells or failure of liver. The hepatitis C may progress to cause liver cirrhosis that mostly develop in 20% of the affected patients in 20 years with an increased risk in male, alcoholic drink, immune-compromised and who acquire HCV infection after the age of 40 years. This was an open-label prospective study conducted on 66 clinically and immunologically diagnosed cases of HCV infection. In Hepcinal treated group, there were significant improvement in HCV associated symptoms compared to control group (p<0.05). While Interferon therapy resulted in significant improvement in serological response (55.88%) compared to Hepcinal treated patients (46.88%). It was concluded that Hepcinal has shown better clinical response but no significant serological response (p=0.3244) and it might be an alternative therapy to treat hepatitis C infection and to prevent its progression into chronic ailment.

Comparative clinical efficacy and safety of coded herbal medicine Dermovix in the management of patients with atopic dermatitis versus allopathic medicine.

Atopic dermatitis (AD) is defined as a chronic, highly pruritic inflammatory condition of skin. It is estimated that this disease may lead significant morbidity and also adversely affects the quality of life. Atopic dermatitis responds well to home treatment. Proper skin care reduces the need for medicines. Topical creams and oral antihistamines can be used to suppress the symptoms. The clinical trial was conducted on 60 patients in which 30 are control and 30 are test by taking written consent from them. Dermovix significantly improved skin symptoms associated with AD. This Dermovix ointment was safe and well tolerated in specified age group patients. Overall results of individual group were analyzed by using Paired sample t-test and level of significance of all the symptoms was calculated. Both the drugs showed similar efficacy and the calculated p value was p<0.05. Except in case of dry skin the test drug had shown not significant p value i.e. 0.407. When we compare all these and their effects and patients' complaints then Test group have shown better results because of no side effects.
