Abstract : Acne vulgaris is the most commonly encountered dermatological disease of pilosebaceous unit. Androgens, which increase during puberty, stimulate the sebaceous gland to produce sebum and cause retention of keratinocytes around the sebaceous hair follicle orifice causing partial to complete blockage and leading to colonization with Propionibacterium acnes, which participates in the production of pro inflammatory mediators. For treatment of acne one of the approaches is to reduce sebum production, the main stimulus to acne; then all other pathogenic factors will diminish. A comprehensive approach combining the natural medicine with anti - androgenic activity would be fruitful area for anti - acne therapy. In this context the well documented anti - androgenic herbs like liquorice and saw palmetto were selected and screened in Syrian hamster ear model using spironolactone as standard. -
Effect of Vitamin C on Bisphenol a Induced Hepato& Nephrotoxicity in Albino Rats
Haroun et al. 57 EFFECT OF VITAMIN C ON BISPHENOL A INDUCED HEPATO& NEPHROTOXICITY IN ALBINO RATS Marcelle R. Haroun,M.D.*, Ibrahim S. Zamzam, M.D.*,Eslam S. Metwally, M.D.*, and Rabab Sh. EL-Shafey, M.S.C. * *Forensic Medicine & Clinical Toxicology Department, Faculty of Medicine, Benha University, Egypt [email protected] [email protected] [email protected] [email protected] ABSTRACT Bisphenol-A (BPA) is a worldwide used endocrine disruptor that is incorporated in many plastic industries. The exposure of humans to that substance starts early during the fetal life. Many agencies raised warnings against the excessive use of such substances. The present study aimed to evaluate the oxidative stress effect of BPA on liver and kidney of albino rats, and whether co-administration of vitamin C can ameliorate this oxidative damage. Albino rats were divided into six groups: -ve control group,+ve control group,vitamin C (60mglkg) treated group, BPA treated group, BPA+ high dose of vitamin C (60mglkg) treated group, and BPA+ low dose of vitamin C (5.5mglkg) treated group The oxidative stress arising from BPA was evaluated in liver and kidney tissues. In addition, serum creatinine, uric acid levels, (AST) and (ALT) activities as markers of kidney and liver function were measured. Biochemical analysis revealed significant reduction in activities of enzymatic antioxidants in BPA treated group and BPA + vitamin C treated groups in high & low doses as compared to control group. In addition, there were significant increase in AST, ALT, uric acid, and creatinine levels in BPA treated group and reduction in their concentrations BPA + vitamin C treated groups in high & low doses as compared to control group. -

Current available therapeutic approaches are not applicable enough for the reason of intolerable side effects, low patients’ compliance due to the short half-life, and biopharmaceutical limitations. Therefore discovery alternative and multi-targeted therapeutic approaches are sought. Crocus sativus is a distinguished medicinal plant with a wide range of biological and pharmacological belongings, exclusively antioxidant and anti-inflammatory possessions. Following PRISMA guidelines, a systematic review was conducted by search in Electronic databases comprising Scopus, PubMed, Web of Science, and Embase using the keywords cognitive OR cognition OR memory OR nootropic OR Alzheimer OR amnesia OR dementia AND “Crocus sativus” OR saffron OR crocin OR crocetin OR safranal until 21st February 2020. The results display that saffron and its major constituents are capable of having remarkable properties on memory and cognitive deficiency. -

Abstract: Alzheimer’s disease (AD) is the leading cause of dementia and cognitive function im- pairment. The multi-faced character of AD requires new drug solutions based on substances that incorporate a wide range of activities. Antioxidants, AChE/BChE inhibitors, BACE1, or anti-amyloid platelet aggregation substances are most desirable because they improve cognition with minimal side effects. Plant secondary metabolites, used in traditional medicine and pharmacy, are promising. Among these are the monoterpenes—low-molecular compounds with anti-inflammatory, antioxidant, Citation: Wojtunik-Kulesza, K.; enzyme inhibitory, analgesic, sedative, as well as other biological properties. The presented review Rudkowska, M.; Kasprzak-Drozd, K.; focuses on the pathophysiology of AD and a selected group of anti-neurodegenerative monoterpenes Oniszczuk, A.; Borowicz-Reutt, K. and monoterpenoids for which possible mechanisms of action have been explained.

What Are Soy Isoflavones? Figure 2: Soy Isoflavones Reduced Plasma Isoprostanes Soy Isoflavones Are a Class of Natural Bioactive Compounds in Soybeans
TECHNICAL REPORT Purina Veterinary Diets® OM Overweight Management® brand canine dry formula and the Beneficial Role of Isoflavones Introduction Approximately 35% of adult dogs in the U.S. are overweight or obese1. A markedly greater incidence of overweight and obesity was observed in neutered male (59% higher) and female dogs (40% higher)1. Chronic obesity can increase the risk of, or complications from, several chronic diseases including diabetes, hypertension, pulmonary and cardiovascular disease, and degenerative joint disease2. Obesity produces chronic, mild inflammation and increases oxidative stress, which, in turn, contributes to the development of the above-mentioned chronic diseases.3,4 Therefore, reducing obesity and oxidative stress can promote a long life span and improved quality of life in dogs. What are Soy Isoflavones? Figure 2: Soy Isoflavones Reduced Plasma Isoprostanes Soy isoflavones are a class of natural bioactive compounds in soybeans. Natural a Marker of Oxidative Stress soy isoflavones include three chemical compounds: daidzein, genistein, 5 Plasma Isoprostanes (ng/ml) and glycitein. Many health benefits have been associated with regular consumption of soy products. In humans, soy has been found to reduce the 4 risk of cardiovascular disease and certain types of cancer (breast and prostate cancer); relieve a number of problems in post menopausal women including 3 hot flashes, osteoporosis, and decline in cognitive function; reduce cholesterol and triglycerides in plasma; improve symptoms of hypertension; and reduce 2 abdominal fat accumulation.5,6,7 1 Why Did Nestlé Purina 0 Control Isoflavones* Choose Isoflavones? *P<0.01 for Control vs. Isoflavones Soy isoflavones provide a number of benefits for managing dogs with obesity, and reducing rebound effects after weight loss. -
