Pilot Study of Trace Elements in the Infusion of Medicinal Plants Used for Diabetes Treatment.

The purpose of this study was to evaluate trace element contents in different medicinal plants used for diabetes treatments by residents in Asir region. Five medicinal plants-Tut leaves (), olive leaves (), clove (), Luban Dhakar (), and Karela or bitter melon ()-were collected from two cities, Khamis Mushait and Abha, in the Asir region, Saudi Arabia. Infusions (hot water extracts) were obtained from each plant, and elemental analysis was conducted using inductively coupled plasma mass spectrometry (ICP-MS).

Phytochemicals, Trace Element Contents, and Antioxidant Activities of Bark of Taleh (Acacia seyal) and Desert Rose (Adenium obesum).

Acacia seyal and Adenium obesum are used in traditional medicines by indigenous communities of the Asir region of Saudi Arabia. The present study aimed to acquire the phytochemical profiles, quantify the trace element contents and the total phenolic (TPC) and flavonoid (TFC) contents, and evaluate the antioxidant activity of the two species. Phytochemical screening was conducted to detect the presence of the phytochemical constituents.

Prediction models for evaluating heavy metal uptake by L. in soil amended with sewage sludge.

The present study aims to develop prediction models for estimating the potential uptake of 10 heavy metals (HMs) (cadmium, Cd; cobalt, Co; chromium, Cr; copper, Cu; iron, Fe; manganese, Mn; molybdenum, Mo; nickel, Ni; lead, Pb; zinc, Zn) by the tissues of (root, shoot and pod) grown in soil amended with sewage sludge (SS) under greenhouse conditions. Soil organic matter (OM) was estimated by loss-on-ignition at 550 °C for 2 h. The pH was determined by shaking the soil and pure water at a 1:5 ratio.

Cytological changes in oral mucosa induced by smokeless tobacco.

Introduction: This study investigated the cellular changes in the mouth of smokeless tobacco (shamma) users among Saudi citizens from the Najran region.

Methods: Healthy 61 shamma users and healthy 61 non-users participated in this study after informed consent. A mouth swap was taken from each study subject and investigated for cellular changes using a Papanicolaou stain.

Estimated dietary intake of essential elements from four selected staple foods in Najran City, Saudi Arabia.

The estimated dietary intake EDI) of essential elements selenium (Se), zinc (Zn), manganese (Mn) and copper (Cu) has not been previously investigated for Najran city, Saudi Arabia. This type of information can be valuable for protecting public health. The aim of this study was to estimate the EDI of these elements.

Evaluation of Selected Essential Elements in Khalas Dates from Date Palm Determined by Inductively Coupled Plasma-Mass Spectrometry.

In terms of nutrition, dates are an important commodity because they are a source of carbohydrates and minerals. Saudi Arabia is the second largest producer of dates worldwide. Khalas is the tenth most popular date type in the Kingdom of Saudi Arabia (KSA), but only limited information related to the levels of essential nutrients in Khalas dates is available.

Levels of Essential Elements in Different Medicinal Plants Determined by Using Inductively Coupled Plasma Mass Spectrometry.

The objective of this study was to investigate the content of essential elements in medicinal plants in the Kingdom of Saudi Arabia (KSA). Five different medical plants (mahareeb , sheeh , harjal , nabipoot , and cafmariam ) were collected from Madina city in the KSA. Five elements Fe, Mn, Zn, Cu, and Se were determined by using inductively coupled plasma mass spectrometry (ICP-MS).

Estimated Dietary Intakes of Toxic Elements from Four Staple Foods in Najran City, Saudi Arabia.

Exposure of the inhabitants of Najran area in Saudi Arabia to the toxic elements As, Cd, Cr, and Pb through foods has not been previously investigated. Exposure to such elements is an important public health issue, so the study described here was performed with the aim of determining estimated dietary intakes (EDIs) for these metals in Najran area. The As, Cd, Cr, and Pb concentrations in four staple foods (rice, wheat, red meat, and chicken) were determined by inductively coupled plasma-mass spectrometry.

Toxic Elements in Different Medicinal Plants and the Impact on Human Health.

Local medicinal plants from Madina, Saudi Arabia, are used to cure various diseases. However, some can cause adverse health effects. Five different medicinal plants were collected in the city of Madina: mahareeb (), sheeh (), harjal (), nabipoot (), and kafmariam ().

Detection of cytological changes in oral mucosa among users of smokeless tobacco (shamma) in the KSA.

Background And Aim: Smokeless tobacco (ST) use is a major cause of cytological changes in the oral mucosa. ST products, such as shamma, which is prevalent in southern Saudi Arabia, raise concerns about the adverse health effects among its users. We evaluated the cytological changes in the oral mucosa of users and nonusers of shamma in the city of Najran, using Papanicolaou staining.

Determination of Metal Levels in Shamma (Smokeless Tobacco) with Inductively Coupled Plasma Mass Spectrometry (ICP-MS) in Najran, Saudi Arabia.

Objective: The use of Shamma (smokeless tobacco) by certain groups is giving rise to health problems, including cancer, in parts of Saudi Arabia. Our objective was to determine metals levels in Shamma using inductively coupled plasma mass spectrometry (ICP-MS). Methods: Thirty-three samples of Shamma (smokeless tobacco) were collected, comprising four types: brown Shamma (n = 14.

Estimation of the 5-methyltetrahydrofolate apparent volume of distribution in humans.

The fractional absorption of a stable isotope-labeled folate dose can be estimated from the subsequent short-term temporal changes in the concentration of labeled L-5-methyltetrahydrofolate (L-5-methyl-THF) in plasma using mathematical modeling. However, the model is dependent on the use of an accurate value for the apparent volume of distribution of L-5-methyl-THF. Previous studies that estimated the apparent volume of distribution of L-5-methyl-THF used large (nonphysiological) doses of unlabeled folates that are not found to any great extent in the circulatory system.

Effect of fasting on the pattern of urinary arsenic excretion.

Millions of people in some of the poorest regions of the world are exposed to high levels of arsenic through drinking contaminated water. It has been reported that development of cancer caused by arsenic exposure in such populations is dependent on dietary and nutritional factors which can modulate arsenic metabolism. Many people in arsenic exposed regions of Bangladesh and India practice fasting for at least one month every year when they refrain from consumption of food and fluid during daylight hours.

Understanding arsenic metabolism through a comparative study of arsenic levels in the urine, hair and fingernails of healthy volunteers from three unexposed ethnic groups in the United Kingdom.

Very little is known about arsenic (As) metabolism in healthy populations that are not exposed to high concentrations of As in their food or water. Here we present a study with healthy volunteers from three different ethnic groups, residing in Leicester, UK, which reveals statistically significant differences in the levels of total As in urine and fingernail samples. Urine (n = 63), hair (n = 36) and fingernail (n = 36) samples from Asians, Somali Black-Africans and Whites were analysed using inductively coupled plasma mass spectrometry (ICP-MS) and graphite furnace atomic absorption spectroscopy (GF-AAS).
