Effects of Two Different Doses of Zinc Sulfate on Serum Troponin I 3 Enzyme Level and Cardiac Malondialdehyde Contents in Mitoxantrone-Induced Cardiotoxicity in Rats
...Show More Authors

Abstract

   Mitoxantrone is an antitumor agent used in the treatment of breast and prostate cancer, acute leukemia, lymphoma, and also in the treatment of multiple sclerosis due to its immunosuppressive properties. The mitoxantrone's cardiotoxicity is irreversible, dose-dependent, and it may occur years after treatment. Zinc is considered as an essential mineral for cell division and the synthesis of DNA and protein; furthermore, such mineral has an important role in states of cardiovascular diseases; and may have protective effects in coronary artery disease and cardiomyopathy.

Objective: The current study is designed to investigate effects of two different doses of zinc sulfate on mitoxantrone-induced cardiotoxicity in rats.

Methods: Forty-eight (48) adult rats of both sexes were utilized in this study; the animals were randomly divided into six groups of 8 animals each. Group I: distilled water (negative control). Group II: orally-administered zinc sulfate (15mg/kg/day) Group III: orally-administered zinc sulfate (30mg/kg/day) Group IV: Intraperitoneally injected with a mitoxantrone at a dose (2.5 mg/kg) to reach total cumulative dose of 7.5 mg/kg on day 20. Group V: Orally-administered zinc sulfate at a dose (15mg/kg/day) and an intraperitoneal injection of mitoxantrone at a dose (2.5 mg/kg) was administered to reach total cumulative dose of 7.5 mg/kg on day 20. Group VI: Orally-administered zinc sulfate at a dose (30 mg/kg/day), and an intraperitoneal injection of mitoxantrone at a dose (2.5 mg/kg) to reach total cumulative dose of 7.5 mg/kg on day 20.

Forty-eight (48) hr after the end of treatment duration (i.e. at day 22 nd), each animal was euthanized by diethyl ether and ketamine. Then, after cervical dislocation, blood was obtained by intracardiac puncture and then serum was prepared to estimate cardiac troponin I 3 enzyme activity levels; and the heart of each animal was excised for homogenate preparation to estimate of malondialdehyde contents.

Results: Oral administration of zinc sulfate [(15mg/kg/day with total cumulative dose (7.5 mg/kg) of mitoxantrone] (Group V) resulted in a non-significant (P>0.05) difference in serum activity level of troponin I 3 enzyme and malondialdehyde contents in cardiac tissue homogenate compared to the corresponding serum enzyme activity level and contents in group of rats intraperitoneally injected with total cumulative dose of 7.5 mg/kg of mitoxantrone (Group IV). In contrast, there were significant reduction (P<0.05) in serum activity level of troponin I 3 enzyme and malondialdehyde contents in cardiac tissue homogenate of rats orally-administered zinc sulfate [(30 mg/kg/day) with total cumulative dose (7.5mg/kg) of mitoxantrone] (Group VI) compared to the corresponding enzyme activity levels and contents in group of rats intraperitoneally-injected with total cumulative dose of 7.5mg/kg of mitoxantrone (Group IV).

Conclusion: zinc sulfate at a dose (30 mg/kg/day) diminishes the cardiotoxicity induced by mitoxantrone via a free radical scavenger property but it is non signifant compared to (15 mg/kg/day) .

Evaluation of the Relation between Asthma, Obesity and Leptin Level in Iraqi Asthmatic Patients and the Main Risk Factors that are Associated with Leptin Level
...Show More Authors

This study tries to clear the correlation and association between asthma, obesity and leptin levels. Also it will work to indicate the main risk factors which play role in the elevation of leptin level within asthmatic patients.  This is a case control study conducted on (38) asthmatic patients and (20) healthy control who were closely similar by age, gender and BMI. The main statistical tests used were student t test, linear regression test and correlation test. Significance was set at P < 0.05. Sampling method used for this study was convenience sampling method.  The main results of this study show a significant association and positive correlation between age (old age  â‰¥ 40 ye

Correlation between Levels of Serum Prolactin and Total Sialic Acids Concentrations in Fertile and Infertile Women
...Show More Authors

The aim of this study was investigating the correlation between elevation of Prolactin levels and the increase of the concentrations of total sialic acids. The study was performed on 149 women consisted of 93 infertile hyperprolactinimic women (patients), age ranged16-38 years old, and 56 normoprolactinemic women as a control group, 18-37 years old. Serum prolactin (PRL) and gonadotroph hormones (Follicle stimulating hormone FSH and Luteinizing hormone LH) were measured using enzymatic immunoassay (EIA) method, resorcinol method for serum total sialic acids (SIA). Patients were divided into four groups, each group represented the level of prolactin of infertile women as follow: G1= (21-30), G2= (31-40), G3= (41-50), and G4= (51-60) ng/mL. S

Diagnostic values of serum IL-17A and IL-18 in Rheumatoid arthritis and Correlation with treatment
...Show More Authors

Background: Rheumatoid arthritis (RA) is an autoimmune disorder that involves autoantibodies attacking and weakening joints. RA is characterized by leukocyte (Monocyte, Lymphocyte mast cell .etc) infiltrations into the synovial compartment leading to inflammation in the synovial membrane.   Synovitis leads to the release of pro-inflammatory cytokines, matrix metalloproteinases, chemokines, complement proteins, and growth factors. Objective: The current study pointed to verify the diagnostic values of interleukin -17 A and interleukin -18 in Rheumatoid arthritis (RA) patients and the effect of treatment thereon. Study subjects and methods: A total of 88 samples with RA were selected from the health clinics of AL-Yarmouk

SYNTHESIS AND CHARACTERIZATION OF SOME NEW METALS COMPLEXES OF 2-(3-ACETYLTHIOUREIDO)-3-PHENYLPROPANOIC ACID (APA)
...Show More Authors

ABSTRACT : A new ligand [ 2- (3-acetylthioureido)-3-phenylpropanoic acid (APA) is synthesized by reaction of acetyl isothiocyanate with phenylalanine (1:1). It is characterized by micro elemental analysis (C.H.N.S.), FT-IR, (UV-Vis) and 1H and 13CNMR spectra. Some metals ions complexes of this ligand were prepared and characterized by FT-IR, UV-Visible spectra, conductivity measurements, magnetic susceptibility and atomic absorption. From results obtained, the following formula [M(APA)2] where M2+ = Mn, Co, Ni, Cu, Zn, Cd and Hg, the proposed molecular structure for these complexes as tetrahedral geometry, except copper complex is has square planer geometry.

Cold atmospheric plasma (CAP) is used widely in medical and biological fields because of non-thermal effected. Direct application of plasma is preferred in medical functions, so, direct application of cold plasma has obtained by the floating electrode dielectric barrier discharge (FE-DBD) system.
