journal of al-qadisiyah for pure science(quarterly), 2015, Volume 15, Issue 3, Pages 11-25

The current search results revealed the presence of anatomical changes on the architectural levels in the noses of Iranian frogs affected by the polluted environment of Karun river which led to subsequent events of physiological adaptations subjected to biophysical equations previously approved in order to save the life of internal stability (homeostasis) and life of these animals that were affected by the polluted water in the Karun River along the Iraqi border. Results showed that radii slots of frog's noses widened by 0.068-0.07 mm and almost step-by-step along this short noses. On the other hand the physiological adaptations of these animals focused on increasing the volume and pressure of gases within the fading waterways in order to balance the ratio of oxygen deficient environment in the contaminated river with change in the values of the constants of equations related to this case.
Conclusion of this research proves that Iranian frogs that are internationally unique were suffers from anatomical defects that had, in turn, contributed to a somewhat equivalent lack of oxygen needed for vital events within the studied river environment and this will lead to similar studies in humans and other organisms that affected by the polluted environment of rivers and what may happen to them regarding the conformations and modifications from these pollutants.

The present study aimed to investigate of host specificity and know how incidence of
cross transmission of Cryptosporidiosis which infected birds to human through tested
incidence of experimental infection with Cryptosporidium spp. which isolated from birds
in white mice balb/c .
To attainment this purpose a laboratory mice were dosage with difference species of
cryptosporidium which isolated from wild and domestic birds and then we determinate of
susceptible of age group to infection and histological changes in experimentally infected
mice. Laboratory mice divided into two age's group: Immature and mature mice ,
experimentally groups were gave a limited infection dose orally for each species of
parasite (1X103oocyst / mouse).
Result showed that cross transmission could happened for three species of
Cryptosporidium that infected birds to lab. mice which are: C.parvum,C.meleagridis and
C.baileyi with total ratio 30% and showed a significant difference compared with control
group , and the results record a mortality ratio in infected mice (7.5%).
The probability of mammalian infection by Cryptosporidium species which isolated from
birds in our study represent the first record in Iraq. C.parvum and C.meleagridis showed
loss of host specificity whereas C.baileyi was opportunist in his ability to infect another
host beside their ordinary host (birds), while C.galli showed a high specificity for its host.
The results showed a distinction of immature mice on mature mice with a significant
difference (35% vs 25%).The histological sections of intestine from infected mice
showed : one of parasite's phase was adhere to epithelial cells and noted a histological
changes which included: cohesion of neighboring villi , dwarf of villus , necrosis of their
top and infiltration of inflammation cells nearby infection regions

This study was performed during 2013 in Al-Batool hospital / Baquba, for fifty pregnant women. The ages were between (17-50) years who had been getting abortion as compared with (24) healthy women as control group (same age) . When the activity of thyroid hormones ( Triiodothyronine , Tetraiodothyronine - thyroxine and Thyroid stimulate hormone) were measured for both cases. Results showed that high rates of abortion had been occurred in the first trimester of pregnancy period while the low rates were in the second trimester of pregnancy period. The results also showed no significant relationship with respect to age among women who had undergone abortion, compared with control group. The study also showed that there was significant correlation between high rates Thyroid stimulate hormone with the number of women get abortion.

journal of al-qadisiyah for pure science(quarterly), 2015, Volume 15, Issue 3, Pages 149-161

In this work, a linear quantitative structure–property relationship (QSPR) model is presented for the prediction of Viscosity[η] for Plasticizers. Structural parameters were derived from the structures of minimum energy obtained by molecular mechanics(MM+) and the semi- empirical molecular orbital (AM1) calculations. QSPR model includes some molecular properties, regression quality indicates that these descriptors provide valuable information and have significant role in the assessment of the Viscosity of Plasticizers. This model provides good results, when the model depends on eight parameters [T.E, V.W.V, Mass, H.E, LUMO,V, ΔE and HOMO], with correlation coefficient R2 = 0.905 for 21 Plasticizers.

The effect of heat treatments on the tensile properties and impact toughness of (6063) aluminum alloy have been studied. This study aims to preparing the aluminum alloy (6063) and study the effect of solid solution temperature, ageing time and the ageing temperature on the tensile properties and impact toughness. Preparing alloy samples were homogenized at 560℃ for 2h, then they were solution heat treated at various temperatures (500, 530,560)ºC for 1 h and then rapidly quenched in water at room temperature. The quenched specimens were then aged at (150,175, and 200)ºC for different time periods. The results showed that the best solution treatment temperature is 530ºC and the best ageing temperature is 175ºC. The highest value of the tensile strength and yield stress are (288.6 and 264.5)Mpa respectively, in samples aged at 175ºC for 6h, while the highest value of impact toughness is 24.6J in samples aged at 175ºC for 2h. The specimens with the lowest impact toughness corresponds to the highest value of the tensile strength and yield stress for all ageing temperature

Present study was carried out to find the effect of Pegenumharmala on liver tissue, liver
function test and some blood parameters on experimental animals, thus for this purpose ,Four
groups of male albino rats (Musmusculus) were subcutaneously administrated with normal
saline(0.9 % NaCl) or Peganumharmala aqueous seed extract (1%,2%,3%) mg/ kg)/body
weight at daily interval for one month period. Thereafter, animals were scarified and
specimens from the liver were examined under light microscope for structural changes.
Repeatedtreatment withPeganumharmala seeds aqueous extract caused dose- related
structural changes in the liver treated groups. Severe changes were observed following 2 %
mg/ kg dose that were manifested by fibrosis in interstitial connective tissueand blood vessels
of the liver. repeated treatment of Peganumharmal water extract a seeds at 3% mg/ kg dose
caused severe destruction of hepatic cellnucleiand vesiculation in the cytoplasm due to
degeneration in hepatic cells .In addition, dis arrangement in hepatic sinusoids and destruction
in the walls of central veins wereobserved. Nuclear polymorph cellular infiltration and
cirrhosis as wellas pyknotic in hepatic cell nuclei were noticed in the 1% mg/ kg dose group.
Peganumharmala seedsaqueous extract at 1% and 2% mg/ kg caused slight to
moderatehistological changes in the liver manifested as degeneration and hypertrophy of
tubular epithelial lining. In addition,The oral administration of extractcauses maximum fall
of blood glucose level to(138 and 35.5 ) at(p<0.01) respectively with the normal
ratsCholesterol was decreasedsignificantly ( 0.01 ) in treatedgroup compared with control .
Lowestvalue was in second dose 2% (29.0) while the highest value was in control group
(148.5),significant changes (0.05) in GPT and GOT enzymes were observedbetween treated
and control group. The highest values were incontrol groups while the lowest values were in
treated groupNon-significant changes were observed in the values of WBC and RBC intreated
rats compared to controls. In conclusions Peganumharmala seed extract has many
histopathological effect on liver tissue as well as moderate effects on liver enzymes and
some blood parameters.
