QUANTIFICATION OF HEAVY METALS, STEROIDS, AND THEIR HEALTH RISK ASSESSMENT IN LOCALLY MARKETED FACE WASH OF PAKISTAN Dua Fatima The widespread use of face wash products in Pakistan requires a detailed investigation into their chemical composition and potential health effects, especially regarding undeclared hazardous substances. This research addresses a significant public health and environmental issue by measuring heavy metals, including Cadmium (Cd), Chromium (Cr), Copper (Cu), Nickel (Ni), and Lead (Pb), as well as steroids, in locally marketed face wash products. It also evaluates the associated risks to human health and the environment. The purpose of the study is to establish the level of contamination, health risks, evaluate environmental effects, and recommend improvements in the regulation. This was done with a survey of consumer awareness, physicochemical study, and proper quantification of heavy metals through atomic absorption spectrophotometry as well as steroid (Betamethasone and Hydrocortisone) by High-Performance Liquid Chromatography (HPLC). Health risk assessment was carried out in the form of calculation of the Chronic Daily Intake (CDI) and Hazard Quotient (HQ). PP. 75; ill

STUDY OF ANTIOXIDANT AND ANTIEMETIC POTENTIAL OF WILDLY GROWING HERBS (Parthenium hysterophorus & Coronopus didymus) Uniba Tariq Herbs are the plants which have aromatic and fragrant properties which are either grown as food or to treat various illnesses. Use of herbs and natural resources of medicines leads to a system of treatment and prevention which is much more effective and has lesser side effects. These herbs also have antioxidants in them which have been proven highly beneficial for a lot many purposes. Antioxidants are the compounds that inhibit oxidation reactions. These antioxidants stabilize the unstable free radicals in order to put a stop to the damage and adverse effects that these free radicals or molecules may cause. This study contains two major parts which is evaluation of antioxidant activity and antiemetic activity. Vomiting or emesis is an involuntary, forceful expulsion of the contents of the stomach through the mouth and sometimes the nose. Emesis is mostly induced by the side effects of chemotherapy, sickness of motion, anesthetics, opioid analgesic or any other illnesses and emesis is usually treated by antiemetic agents which efficiently work against emesis. The main objective of this study is to determine the antioxidant and antiemetic activity of two herbs i.e. Parthenium hysterophorus and Coronopus didymus in order to find out their medicinal use.

Effect of Antioxidant Fractions of Convolvulus arvensis and Fumaria officinalis on Hematological Parameters of Rabbit Masooma Mehmood Plant extracts are used extensively to treat many diseases. Many herbs extracts possess antimicrobial activity against a wide range of bacteria, yeast, molds and viruses due to phytochemical constituents. In this study extracts of Fumaria officinalis and Convolvulus arvensis were used. The main objectives of this study were to examine the in-vitro antioxidant and in-vivo hematological parameters of Convolvulus arvensis and Fumaria officinalis, to evaluate the effects of antioxidant fractions of two herbs on hematological parameters of rabbits, to evaluate the medicinal use and value of selected herbs. Various fractions were used to determine the antioxidant activities using Hydrogen peroxide, Phosphomolybdenum and DPPH assays. In H2O2 assay, methanolic extract of F. officinalis and C. avensis showed a pretty good percentage of antioxidant activity 82% to 90% at the highest concentration i.e, 1 mg/ml. Both C. arvensis and F. officinalis showed 88% of antioxidant effect through DPPH radical scavenging assay. PP. 49 ill;
