Ismail H. Mohammed, Nabeel A. Al-Hussary, Ismail Salih Al-kakey

Pages: 1-8 Arabic

Abstract

The effect of daonil and its combination with Paracetamol or oxytetracycline in
glucose and cholesterol levels in blood of normal and alloxan induced diabetic rats were
investigated. Diabetes induced by injection of (100 mg/Kg body weight) of alloxan .
Daonil ( 1mg/Kg body Weight) showed reduction in the level of glucose in normal and
dibetic rats. Neither combination of daonil with paracetamol nor with oxytetracyclin
showed significant change in the hypoglycemic effect of daonil in normal and diabetic
rats. Treatment with daonil caused significant decrease in cholesterol level in diabetic
rats, but not in normal rats, while combination of daonil with oxytetracycline caused
significant reduction in cholesterol level in normal rats, but not in diabetic rats.
Combination of daonil with Paracetamol showed non significant effect in cholesterol
level in normal and diabetic rats.
In conclusion the results of this study revealed, a beneficial effect of daonil treatment
in insulin dependent diabetes mellitus, and its activity not affected by its combination
with paracetamol or oxytertracycline.

Abstract

درس تأثير الداؤنيل وترافقه مع الباراسيتامول او الاوكسي تتراسايكلين في مستويات الكلوكوز
والكوليسترول في دم الجرذان السليمة والمصابة بداء السكر المحدث بالالوكسان. استحدث السكري بحقن
الجرذان بالالوكسان ( 100 ملغم/كغم وزن الجسم). اظهر الداؤنيل (ا ملغم/كغم وزن الجسم) خفضا
معنويًا في مستوى كلوكوز الدم في الجرذان السليمة والمصابة بداء السكر، ويعزى ذلك الى قدرة الداؤنيل
على زيادة افراز الانسولين، وتحسن استهلاك الكلوكوز، والحد من تكونيه في الكبد. لم يظهر ترافق
الباراسيتامول او الاوكسي تتراسايكلين مع الداؤنيل تغيرًا معنويًا في تأثير الداؤنيل في خفض مستوى
الكلوكوز في الجرذان السليمة والمصابة بداء السكر. اظهر الداؤنيل خفضا معنويًا لمستوى الكوليسترول
في دم الجرذان المصابة بداء السكر وليس في الجرذان السليمة، واظهر ترافق الاوكسي تتراسايكلين مع
الداؤنيل خفضا معنويا لمستوى الكوليسترول في دم الجرذان السليمة وليس في الجرذان المصابة بداء
السكر مقارنة بمستواه في مجموعة المعاملة بالداؤنيل لوحده، في حين لم يظهر الباراسيتامول بترافقه مع
الداؤنيل تأثيرًا معنويًا في مستوى الكوليسترول في دم الجرذان السليمة والمصابة بداء السكر مقارنة
بمستواه في مجموعة المعاملة بالداؤنيل لوحده. نتائج الدراسة هذه في خفض مستويات الكلوكوز
والكوليسترول بوساطة الداؤنيل في داء السكر المعتمد على الانسولين تفترض وجود الية لفعل الداؤنيل في
مواقع خارج البنكرياس، وان ترافقه مع البارسيتامول والاوكسي تتراسايكلين لا يؤثر في فعاليته المفيدة

Abstract

The study included genetical analysis of the means for six generations namely P1,
P2, F2, F3, BS1 and BS2 of two crosses in a six row barley (Jezera – 1 X Bendicat and
Baraka X Arivate) to estimate the genetic parameters that control following traits: plant
height grain yield, number of spikes per platnt, spike length, weight of 100 grains and
number of grains per spike . The grains of the six generations were planted at Botanical
experimental station, college of education, Mosul University in the growing season 2001-
2002 using C.R.B.D. with four replications. The rasults indicated that three – parameter
modol was adequate for number of spikes per plant in the second cross .

Abstract

Mycological investigation of (100) samples of powdered milk collected from
different food stores in Mosul city. During the period from June 2002 to October 2002,
reviled that Aspergillus spp., and Penicillium spp were occurred at the concentration of .42 %, 47.14% for the Infant milk and 31.75 %, 55.55 % for the Adult milk
respectively. To a lower order were Cladosporium herbarum, Geotrichium spp, Rhizopus
stolonifer , Scopulariopsis spp . Aspergillus flavus was occurred at a rate of 22.86 % and
14.29 % in infant and adult milk samples respectively. Aflatoxin were detected in (6)
A.flavus isolates (37.5 %) infant milk and in (2) A.flavus isolates (22.2 %) in adult milk
samples. Aflatoxin B1 was estimated to be 18 ppb and 16 ppb in infant and adult milk
A.flavus isolates and aflatoxins produced by them were discussed.

Presence of Dihydrofolate Reductase in Seedlings and Callus of Nigella Sativa L. Plant.

Pages: 26-38 Arabic

Full Text Issues

Abstract

The study aimed to investigate the biosynthesis of thymidine nucleotide by salvage
and de novo pathways in the black seed (Nigella sativa L.) plant. The results indicated
the absence of thymidine phosphorylase activity in the cell extract of black seed plant
while dihydrofolate reductase was present. This may indicate that black seed cells depend
on de novo pathway for dTMP synthesis.
Callus induction occurred on stem segments of Nigella sativa L. seedlings grown on
Murashige and Skoog medium, containing 10-6M of 2,4-D .
Specific activity of dihydrofolate reductase and total folate content of black seed
callus reached 24,13,8,4 and 3 folds than that found in seeds, roots, flowers, stems and
leaves respectively.
Moreover, the results indicated an increase in the fresh weight with an increase in
the cellular contents of proteins, nucleic acids (DNA and RNA) and folate extracted from
callus of deferent ages. The specific activity of dihydrofolate reductase followed the same
pattern of the cell components.

Modification of Rheological Properties of Asphalt by Treatment with Reclalaime Rubber from Scrap Tires\Effect Modification Treatment on the Properties of the Modified Asphalt

Niem M. Al-Layla

Pages: 39-46 Arabic

Full Text Issues

Abstract

Reclaimed rubber of scrap tires is added to modify the physical characteristics of
asphalt in two manners. The first ones depends on combining the rubber molecule with
some of the asphalt. The second one depends on the same principle in addition to adding
sulphur to formulate sulpharized compounds. The out come of these asphalt patterns and
their physical characteristics are specified. The results of this study indicate that these
modified asphalt patterns are characterized by having little thermal sensitivity in
comparison with unmodified normal asphalt.

Pages: 47-61

Abstract

The results of engineering, geochemical and mineralogical analysis revealed that it
is possible to manufacture a new type of pottery blocks with good building
properties.This has been achieved by mixing of marl sediments from Fathَa formation (Middle Miocene) and recent clay sediments (from valleys around Mosul city) with
different ratios of three types of alluvial river sand normally used for building purposes.
More than one hundred cubic samples (10x10x10 cm) are prepared and pottered in a
high-temperature (1100-1200????C). This was followed by engineering and physical test
after which a group of samples with certain good characteristics (here called typical
samples) were chosen and further experiments were done on their new size (40x20x15
cm) to reach the best required quality.

Marwan A. Dabdoub, Farah A. Younis

Pages: 62-81 Arabic

Abstract

The outliers were founded as results of the regression analysis and also by box
plot graph. The outlier values were tackled by trimmed mean.
The data about the life of premature births and other nine factors were collected
from three records which represented by pre-blockade years 89-1990, the years 94-1995
which are under blockade and before memorandum of understanding and after
memorandum of understanding the years 99-2000. A random sample of size 100
premature births were taken from each period.
It was found that the outliers affected regression analysis results, so it is necessary
to search for outliers whenever regression analysis is needed.
The pregnancy period and the weight of premature had the major effect on his life
in pre-blockade and after memorandum of understanding periods, before the period of
memorandum of understanding two factors were added they were: period of nursery stay
and type of disease that the premature births suffered from. The abortion cases increase in
last period.

Abstract

Rubber compounds consist of group of initial materials mixed together then
molded by compression to produce the final product. The effect of mixing time on the
homogenity and mechanical properties for rubber compound type (MCG) was studied in
this research. The samples under research were prepared in Jaber Bin Hayyan company.
Using the roller and the mixer. The homogenity was studied using the idea of nuclear
radation absorption while the mechanical properties was studied using the (Tera – test )
instrument. In this study it was found that the best time of mixing is (6) mint. using the
mixer and (20) mint. using the roller.
