Published: April 2023

The season is an important factor determine the efficacy of the sexual activity of the adult males of different animal species, in this study, Sixteen adult male rabbit of local breed were used to investigate the effect of the different seasons of the year on the histology of the testicular tissue, particularly the leydig cells. Four animals were killed in each season and segments of testes processed by using histological technique. The results were indicated that the seasons winter and summer affect the seminiferous tubules reflected by subpopulation of different germ cells such as spermatogonia, primary and secondary spermatocytes, spermatids and spermatozoa. Leydig cells were atrophied with deeply basophilic nuclei associated with poorly blood capillaries in between, otherwise the seasons spring and autumn effect on the same germ cells and leydig cells, but in this case there was increase in the population of germ cells in the seminiferous tubules and the leydig cells were hypertrophied with the presence of cytoplasmic fat droplets and its nuclei were euochromatic, The blood capillaries in between these cells were abundant, these events indicated the increase activity of testicular tissue in both seasons, the (spring and autumn), While in winter and summer, this phenomena was contra versa. The present study was indicated that the spring and autumn seasons are the best for the progressed activity of the leydig cells and germ cells of the testicular tissue of the adult rabbit than the winter and summer seasons.

Published: April 2023

The early identification of some clinically significant hemoglobinopathies and precise differentiation of hemoglobin variants are important to provide early comprehensive medical care to prevent some serious complications, assess prognosis and offer genetic counseling.
This study examined the prevalence of α 2 - gene deletion in neonates in Samarra and Tikrit, Iraq. Screening study was carried out by examining fresh blood samples obtained from excised umbilical cord of 42 neonates born in neonates clinics in Samarra hospital and Tikrit hospital from October 2012 to March 2013. Hemoglobin electrophoresis were performed using Hellabio hemoglobin electrophoresis kit (He 10) and Hellabioscan system for detection of Hb bands and value % of fractions.
The results showed 40 cases out of 42 (95.24%) have normal hemoglobin components. 2 cases out of 42 (4.76%) there was no visible band of HbA2 in hemoglobin electrophoresis pattern. Considering the missing of HbA2 band the two cases may have the deletion of δ gene so each one of them may has the genotype δ0/δ0.

Authors: Shaimaa Essa Ahmed  , Firas Taher Maher  , Nazar Ahmed Naji  
Published: April 2023

Background: Obesity is characterized by abnormal or excessive fat accumulation that is the result of a chronic imbalance between energy intake and energy expenditure. Thyroid hormones have profound effect on many physiological processes, such as development, growth in children and metabolism. Thyroid hormones stimulate diverse metabolic activates in most tissues, leading to an increase in basal metabolic rate. Trace elements are essential nutrients with regulatory, immunologic, and antioxidant functions resulting from their action as essential components or cofactors of enzymes throughout metabolism.
Methods: In this study conducted on 176 individuals in the age group from (20-55) years, from Tikrit and Kirkuk Governorates. Blood samples were divided into three groups according to BMI: Group One: Control group (Normal Weight): 66 individual BMI (18.5 - 24.9 kg/m2). Group Two: Overweight group: 50 individual BMI (25.0 – 29.9 kg/m2).Group Three: Obese group: 60 individual BMI (≥ 30 kg/m2).
Results: The results showed a high significant increase (p<0.0001) in the BMI level in obese and overweight groups comparison with normal weight group. The results showed a significant decrease (p<0.001) in (T3 and T4) hormones levels in obese and overweight groups comparison with normal weight group. While the results showed a high significant increase (p<0.0001) in the TSH levels in obese and overweight groups comparison with normal weight group, the results showed a significant decrease (p<0.001) in the Zn concentration in obese and overweight groups comparison with normal weight group, the results showed a high significant decrease (p<0.0001) in the Mg concentration in obese and overweight groups comparison with normal weight group. There is a high significant increase in the (cholesterol, TG, VLDL-c and LDL-c) levels in obese and overweight groups comparison with normal weight group (p<0.0001), while the results showed a high significant decrease (p<0.0001) in the HDL-c level in obese and overweight groups comparison with normal weight group. The results showed that there was a significant positive correlation between T3 and T4.While there was a significant negative correlation between T3 and LDL. There was a positive correlation between T4 and HDL. Whereas the there was a significant negative correlation between T4 and LDL. There was a significant positive correlation between TSH with Cholesterol, Triglyceride, LDL and VLDL. There was a significant negative correlation between TSH with HDL, and Mg. Conclusions: The results of (thyroid hormones and lipid profile) indicated highly associated with trace elements (Zn, Mg) levels and these correlations may be caused a risk of the obesity

Published: April 2023

In this work, the cationic surfactant hexacetyl pridinium chloride (HCPC) was blended with anionic surfactant Sodium Dodecyl benzene Sulfate (SDBS) by using different concentrations (0.0025 - 0.1M) of phenol and at temperature ranges (20-35 Co). It was found that the viscosity values for the mixture of SDBS / HCPC at a certain mixing ratios (12/3, 10.5/4.5 and 9/6), were increased in the presence of phenol, due to formation of self-assembled supramolecular. Moreover, the thermodynamic functions as well as the activation energy for the process of self-assembled were calculated. Conductivity measurements were also performed for further support. The results revealed a physical interaction insight intermolecular forces.
