Abstract

AbstractThe aim of this study was to determine the prevalence of dental erosion among 10-12 year old children in Mosul city, mean erosion in teeth and surfaces, amount ofcarbonated beverages and fruit juice consumed in the sample, and the correlationbetween dental erosion and some variables. Total sample consisted of 400 childrenderived from different primary schools in the city center. Examination was performedaccording to tooth wear index by Smith and Knight 1984 modified by Millword et al1994.Results showed that dental erosion was highly prevalent 74.2% in the sample,increasing with increasing age, with boys showing a higher prevalence in dentalerosion compared to girls with significant difference. Mean erosion scores for primaryteeth were slightly less then permanent teeth, with a significant difference between 10and 12 years of age for both dentitions.Buccal/labial surfaces exhibited more erosion, followed by lingual/palatal andfinally occlusal /incisal surfaces, with boys showing more erosion in all surfaces thangirls. A large proportion of the sample consumed carbonated beverages 3-5 /weekwith boys consuming more than girls as seen in the erosion group, fruit juice was alsolargely consumed by the sample, especially the group that showed erosion. A positivecorrelation was found between erosion, level of father’s education, time of drinking,method, amount of carbonated beverages and fruit juice consumed.Preventive measures are considered to be the only effective course of managementof dental erosion, by reducing intake of carbonated beverages and fruit juice, alsomodification of erosive drinks, medicines and foods may prove to be an acceptable future strategy world wide

Abstract

Forward osmosis (FO) process was applied to concentrate the orange juice. FO relies on the driving force generating from osmotic pressure difference that result from concentration difference between the draw solution (DS) and orange juice as feed solution (FS). This driving force makes the water to transport from orange juice across a semi-permeable membrane to the DS without any energy applied. Thermal and pressure-driven dewatering methods are widely used, but they are prohibitively energy intensive and hence, expensive. Effects of various operating conditions on flux have been investigated. Four types of salts were used in the DS, (NaCl, CaCl2, KCl, and MgSO4) as osmotic agent and the experiments were performed at the concentration of the salts in the DS ranged (3.5 – 20% by wt), the temperature of DS ranged (20 – 50oC), and the flow rate of the FS and DS ranged (1 – 4 lit/min). It was observed that the optimum operating conditions are: concentration of salt = 20% by wt for CaCl2, temperature of DS = 50oC, and the flow rate of FS = 4 lit/min where at these conditions the maximum flux was obtained equal to 13.2 lit/m2.h or the total volume of the water transferred from the juice (during 3 hours and membrane area of 0.0135 m2) was 0.535 lit. NaCl performed much higher efficiency as osmotic agent than the others salts up to the concentration of 15.2%, but after 15.2% the CaCl2 was the best.

Abstract

This study was conducted to evaluate the anticancer effect of Eriobotrya japonica (loquat) fruit juice on cancer cell lines (in vitro) and its antioxidant activity. Study was performed on two cancer cell lines, human cervical cancer (Hela), rhabdomyo sarcoma (RD), and rat embryogenic fibroblast (REF) as a normal cell, at concentrations of 62.5, 125, 250, 500 and 1000 µg/ml of fruit juice were measured at 24, 48, and 72-hr. with three replicates. Free radical 1,1Dyphenyl-2-picrylhydrazyl radical (DPPH) was used for testing the ability as antioxidant on 25, 50, 75, 100, 150 µg/ml concentration of the loquat fruit juice. The results revealed that the juice of E. japonica had high antioxidant influence (100%) in 150 µg/ml concentration, followed by 88% in 100 µg/ml concentration. Effect of growth inhibition of cancer cells was depended on juice concentration. The effect of juice on Hela cell line was more than on RD, while the highest effect of juice on Hela was shown on concentration of 500 µg/ml the 48 hr. The cytotoxic effect of exhibited that had a significant effect (P<0.05).

صممت هذه الدراسة لتقدير تأثيرعصير ثمار نبات الينكي دنيا Eriobotrya Japonica كمضاد على الخطوط السرطانية (خارج الجسم الحي) والفعالية المضادة للاكسدة. شملت الدراسة خارج الجسم الحي على نوعين من الخطوط السرطانية (Hela) و(RD) والخط الطبيعي (REF). ان فترة تعرض الخطوط الخلوية لتراكيز العصير 62.5 أو125 او250 او500 او1000 µg/ml كانت 24 أو 48 أو 72 ساعة خلوي ولثلاث مكررات لكل تركيز. استعمل الجذر الحر radical 1,1Dyphenyle-2-picrylhydrazyl (DPPH) في اختبار مار كمضاد للاكسدة عند التراكيز 25 أو50 أو75 أو100 أو150 µg/ml. اظهرت النتائج ان لعصير الثمار فعالية مضادة للاكسدة 100% عند التركيز 150 µg/ml ثم تبعها 88% عند التركيز 100 µg/ml. ان تأثير العصير على تثبيط نمو الخلايا السرطانية يعتمد على التركيز وفترة التعرض له ونوع الخلايا السرطانية فقد تفوق تأثير العصير على الخط الخلوي Hela على الخط RD)) فكان اعلى تأثير للعصير على (Hela) عند التركيز 500 µg/ml بعد 48 ساعة تبعها 24 ساعة عند نفس التركيز. اما الخط الخلوي الطبيعي (REF) فكان تأثير ثمار النبات على الخلايا واطيء جداً مقارنة بتأثير على الخطوط السرطانية. ان التأثير السمي العالي للعصير قد أعطى تأثيراً معنوياً (0.05>P).

Abstract

This study focused on estimating levels of some heavy metals in five brands of fruit. Heavy metals was determined by Atomic absorption spectrometry ( AAS). Concentrations of the studied metals varies between (15.01 ± 2.45) PPm for Fe, (4.23 ± 1.50) PPm for Cu, (1.25± 0.002) PPm for Pb, (0.55± 0.002)PPm for Cd, (1.46 ± 0.47) PPm for Zn. The levels of these metals exceeded statutory safe limits except for Zn
