This study was conducted to know the impact of treatment of cowpea seeds plant oils as following: - Black seed, castor, sunflower, Alsi and Brassica on Southern cowpea weevil C. maculatus at concentration of (1.5, 3, 4.5) ml / kg seeds.
The study showed superiority of mustard oil in reducing the average of number of eggs laid on the seeds as it reached 161.13 while the highest rate reached to 208.25 when the testing seeds treatment with sunflower oil. The study also showed that the longer period for exit of the members of the first generation (F1) 28.08 day when the seed treated with mustard oil, while minimum period of 27.00 days when treated with castor oil seeds. We see that the lowest rate for a number of emerging insects 48.50 at the treatment of linseed oil, while the highest rate for a number of emerging insects 53.50 at the treatment of black seed oil. It was found that the lowest rate of damage was 24.90% with linseed seed oil and the highest rate was 29.73 with black seed oil, While the highest rate was in seed weight 21.60% with black seed oil and the lowest rate was 16.88% with mustard oil, And the treatment of the seeds of cowpea plant oils which was used in this study did not show adverse effects on the vital seed treatment significantly. As the results showed that the amount of oil is inversely proportional to both the number of eggs and emerging insects and the percentage of damage, loss and germination, and directly proportional to the period of time required for the exit of members of the first generation (F1).

A gamma–gamma fast –slow coincidence spectrometer composed of two 3"×3"NaI(Tl) detectors and peripheral electronics is used in investigating some effects on the photo peak after the penetration of gamma –rays from lead. Coincidence measurements are carried out using Na-22 source with selecting the 511 keV gate. Linear and mass attenuation (in cm²/g) coefficients measurements are made using lead sheets with dimensions 10×10 cm. Mass attenuation coefficient was measured for coincidence spectrum at 511 keV and found to be 0.114 and 0.140 for direct spectrum. Also coincidence and direct spectra measurements were carried out using Co-60 source with 1332 and 1173 keV gates. Mass attenuation coefficient at 1173 keV was 0.0460 for coincidence spectrum and 0.0522 for direct spectrum. At 1332 keV the same coefficient was0.0432 for coincidence spectrum and 0.0452 for direct spectrum. Mass attenuation coefficients values from coincidence measurement are lower than those in direct measurement at same energies

Published: April 2023

Chronic Renal Failure (CRF) is the progressive and irreversible loss of normal functioning of kidneys. this is associated with increased levels of some biochemical parameters and decreased others. This study aims to evaluate the value of serum paraoxonase-1 (PON1) activity as biochemical marker for patients with chronic renal failure (CRF) before and after hemodialysis (HD).
The samples of this study consists of 100 patients (55 males, 45 females) and 100 apparently healthy individuals (57 males, 43 females) from 20 - 70 years old of age. All patients included in this study were those who were receiving hemodialysis therapy in the dialysis unit in Kirkuk general Hospital from the period between February 2013 and May 2014. Serum PON1, BU, Cr, TC, TG, HDL, LDL levels were measured by spectrophotometric methods.Paraoxonase1 activity level was significantly lower in cases of CRF patients than in normal healthy control in pre hemodialysis (HD). It's level was significantly increased in post HD (P> 0.05). The blood urea (BU), serum creatinine (Cr), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) were significantly higher than normal healthy control in pre HD (P˂ 0.05), In post HD their levels were significantly decreased as compared to the pre HD (P˂ 0.05) but still lower than normal control, the serum high density lipoprotein (HDL) of CRF patients was significantly lower than normal controls (P˂ 0.05) in pre HD and was significantly increased in post HD as compared to pre HD but remained lower than normal healthy control. Conclusion: PON1 activity was significantly decreased in CRF patients before HD and significantly increased after HD but remained lower than controls. PON1 was significantly and negatively correlated with the age, BMI, duration of disease, BU, Cr, TC, TG, LDL, and VLDL. This study demonstrates that there is an increased risk of cardiovascular complications in CRF patients undergoing hemodialysis by increasing TC, TG, LDL, VLDL and decreasing HDL.

Introduction: Diabetes is a group of metabolic diseases characterized by excessive blood sugar caused by a defect in insulin secretion or function, there are two main types of diabetes: namely, insulin-dependent diabetes mellitus (Type I) known as childhood diabetes, The second type is non-insulin-dependent diabetes mellitus, and usually affects adults after the age of forty. Hepcidin is the main organizer of the iron metabolism inHuman and in the rest of mammals.
The aim of the study:

Examine the relationship between the concentrations of each of the hepcidin, glycated hemoglobin HBA1C and ferritin and iron in patients with type II diabetes as well as healthy control.
Examine the relationship between these virables with each other and with other virables.

Materials and Methods: The concentration of hepcidin hormone and other biochemical variables was examined in (80) patients with diabetes type II, divided into two groups (39) males and (41) females. Age ranged between (34-75) years. Samples have been collected from patients who visited Balad General hospital laboratory and Dijla Private Laboratory in Balad District. At the same time , blood of (25) healthy volunteers was collected. Sample was divided into 2.5 ml in EDTA tube for hematological tests like complete blood count and HbA1C and 2.5 ml in heparin anticoagulated tube for chemical tests like blood sugar, Iron, Total iron binding capacity and Hepcidin.
Results and Discussion: The results study showed a significant relationship (P<0.05) between the concentration of Hepcidinin patients with type 2 diabetes and healthy persons for both sexes . Also hepcidin concentration tend to increase in female patients as compared with male patients.
It was also noted that there was a statistically significant relationship between hepcidin and ferritin concentration (p<0.05), as well as between iron and Hepcidin concentration (p < 0.05), with no statistical relationship between iron binding capacity (TIBC) and the concentration of hepcidin.
The study showed a Positive correlation between the concentration of Hepcidinand count of red blood cells in people with type 2 diabetes when compared with healthy people.
Conclusion: The average concentration of hepcidin was found to be higher among females than that among males. Also, there was an increase in the concentration of Hepcidin compared with healthy people.
