Abstract

One of an ecological hazardous agent Chromium; Cr (VI), The present experimentin vitro design to examine the mechanism of Leydig cell functions of Cr (VI) in ramtestis, Cr (VI) treated groups demising cell growth behavior of exponential phase wasupset of feeding time to Leydig cell in a dose-dependent manner, and inducedmitochondria-dependent ATP depletion and subsequently apoptosis. Cr (VI) effectmay be attributed, at least in part to DNA fragmentation increase DNA tail numberand tail length of COMET as compared with control group. Furthermore, theproperties of cell-specific regulation of cell membrane integrity had reduced anddeterminant cell concentration drop an.d reflected on the testosterone concentrationwere decreased as concentration-dependent manner, In conclusion, our results displaythe Cr (VI) is cytotoxic and impairs both viability and steroidogenic functions ofLeydig cells in ram testis via actually different pathway direct affecting of viabilityand indirect on steroidogenic activity, succeeding in testicular performance. However,the definite modes of action of harmfulness are not evidently unknown and must berechecked and studied in a different aspect

Abstract

This study investigates the effect of different chromium picolinate levels as food supplementation and sex on Japanese quail meat characteristics. Ninety Japanese quail chicks with one day of age were reared in 340C temperature and continuously feed and water providing at the Faculty of Agriculture , University of Diyala animals’ field, vitamins were provided with water and temperature were monitored continuously. Birds were allocated for three treatments with convergent of weight average when reached the age of 14 days, each treatment contain three replicates and ten birds for each replicate, each replicate birds were rearing in cage with 50×50×50cm for four weeks (until 42 day of age), all treatments birds were provide with free same ration and chromium was added to the treatments ration as follows: control treatment: without chromium, treatment one (T1) adding 250µg (0.25mlg) chromium picolinate/kg ration, treatment two (T2) adding 500µg (0.5mlg) chromium picolinate/kg ration. After the period of the experiment finished, six birds were selected randomly from each treatment (three from each sex) and weighted then slaughtered, many measurements were taken from meat and carcasses, including hot and cold carcass weight, dressing percentage, carcass cuts weight, breast and leg cooking loss, thawing loss and meat chemical composition. Statistical analyses show that no clear effect of supplementation on these measurements and no real benefits from adding it with quail ration in this ratio and this experiment conditions and traits. It might be concluded that the chromium presented normally in ration and water was adequate to normal quail requirement and chromium supplementation may not be essential. Higher chromium ratio should be tested.

Abstract

In this researchBardi leaveswere used which are available in high quantity in Iraq to remove Chromium (VI) from wastewater that is considered as an environmental pollution . The experiments were conducted by batch adsorptionsystem..The investigation studied the influenceparameter ( pH , time ,and initial concentration of adsorbent material ). The adsorption efficiency was tested by dissolving Potassium di chromate which is contaminated with milled Bardileaves.The removal efficiencies of (90-95% ) were obtained for pH( 2 – 3 ) and duration time ( 3 – 4 ) hours respectively. All tests were conducted by (UV/VIS spectrophotometer (Model UV-9200)).

تم في هذا البحث استخدام نبات البردي المتوفر بكميات كبيرة في العراق لازالة الكروم السداسي باعتباره مادة ملوثة للبيئة من مخلفات المياه الصناعية , اجريت التجارب المختبرية بنظام الامتزاز ذات الدفعات ، تم دراسة تأثير تغيير (الدالة الحامضية - الزمن - تركيز المادة المازة ) على كفاءة الامتزاز .الكفاءة في هذه العملية تم اختبارها من خلال تحضير نماذج مختبرية لمحاليل ملوثة بالكروم وذلك باذابة داي كرومات البوتاسيوم في الماء المقطر وامرارها على نبات البردي المطحون . الدراسة اوضحت انه يمكن استخلاص الكروم بشكل فعــال عندمــا تكون الدالة الحامضية(H (2 – 3p وبزمن ( 3 – 4 ) ساعات لتصـــل كفـــاءة الامتـــزاز الــــى (90 – 95) % علما ان جميــــع الفحـــوصــات تمــت بواسطـة جهــاز ـ (UV/VIS spectrophotometer Model UV-9200))).الكلمات المفتاحية: المياه الصناعية ، المادة المازة ، الكروم ، نبات البردي ، امتزاز الدفعات .
