Estimation of Testosterone, Estradiol and some Markers in Sera of Iraqi Patients with Benign Prostatic Hyperplasia.

Benign prostatic hyperplasia (BPH) is one of the most common disease and major cause of morbidity in elderly men which may lead to bladder outflow obstruction and lower urinary tract symptoms (LUTS). Although sex steroid hormones play fundamental roles in prostate growth, their clinical significance is not completely clear. In the present study we assessed whether serum hormones levels as markers of prostate disease. This study includes (40) patients with benign prostatic hypertrophy and (40) control group with age rang (41-79) and (42-71) years respectively. The following biochemical investigations have been studied: Testosterone, Estradiol (E2), and Prostatic Specific Antigen (PSA) levels using ELISA method which correlated with the disease. Also body mass index (BMI), the prostate size by digital rectal examination (DRE), flow rate, and American Urology Association Symptoms Index (AUASI), of the patients which correlate hormones levels with age. The testosterone concentrations were significantly lower in patients with BPH than control group (p?0.05), while the Estradiol and PSA concentrations were significantly higher in patients with BPH than control group (p?0.05). The net result is a significant decrease in the T/E2 ratio allowing the imbalance between androgens and estrogen regulation of prostate growth to shift towards estrogen dominance. It has been proposed that increased estrogenic stimulation of the prostate in the aging male may lead to reactivation of growth and subsequent hyperplasia transformatio

ِDiagnosis of causes of suppurative arthritis in sheep in Mosul, Iraq

The prevalence of suppurative arthritis in one hundred sheep from both sexes and different ages were studied. Aspiration of synovial fluid from knee joint of animals showed signs of lameness with reluctant to move in addition to decrease in the body weight and loss of appetite. Physical and bacterial examination of the synovial fluid was revealed green color, turbid and containing pus. Mucin clot showed difference in degree of clotting, and increased number in leukocyte, neutrophile but decreased in lymophocytes and monocyte. The result showed that Streptococcus dysagalactiae was predominate 61.1% while Arcanobacterium pyogenes and Pseudomonas aeruginosa were the less 5.5%, also the result showed that all the strains were more sensitive to the Ciprofloxacin. This study is considered to be the first attempt to isolate bacteria from Sheep joints in Mosul-Iraq

Study the Changes of Thyroid Hormones Levels Following Major Urological Surgery

This study was designed to evaluate the effect of major surgery on thyroid hormones and thyrotropin in patient undergoing major lower abdominal surgery. The study included fifty patients scheduled for elective major lower abdominal surgery, the serum levels of T3, T4 and TSH were determined one day preoperatively, intraoperative, one day postoperatively, two days postoperatively, and rT3 was determined one day preoperatively, and one day postoperatively. We observed that the levels of (T3, T4, TSH) increased significantly (P0.05). rT3 increased not significant (P>0.05) in one day postoperatively. It has been proposed these changes due to surgical stress that inhibits peripheral conversion of T4 to T3 by inhibiting peripheral 5'-deiodinase activity, also The absence of pituitary response to changes in serum levels of T3 and T4.According to the results of this study there is a transient abnormality in thyroid function tests in patient undergoing elective major surgery and this abnormality due to surgical stress

Assessment of Neopterin and Interleukin-1 Beta Serum Levels in Burn Patients

Background: The burn is an injury consisting of the destruction of the skin and the underlying tissues. The neopterin(Neo) is produced by activated macrophages, in response to interferon-gamma derived from activated T cell. Interleukin1 beta (IL-1β) is an important mediator of the inflammatory response. Objective: Estimation of Neo and IL-1β in burned patients to determine the changes in these parameters in relation to percentage of total burn body surface area (TBSA%) and the duration of hospital stay. Patients and Methods: Fifty burned patients who were admitted to West Erbil Emergency Hospital in Erbil governorate were included. Out of 50 burnt patients 20 patients were secondly sampled to follow-up serum levels for Neo and IL- β. The burn patients in this  study was divided into four groups according to the TBSA%. Results: Comparing mean concentration of serum  Neo and IL-1β in burn patients and healthy control revealed increased levels of Neo and IL-1β in burnt patients with increased TBSA% , indeed IL-1β serum level also increased in non-survivor  burn patients compared with survivor patients and HC. Indeed levels of Neo level increased significantly in (10) day post burn. Conclusion: Levels of Neo and IL-1β increased in burnt patients with increased TBSA%, non-survivor  compared with survivor patients and HC. Indeed levels of Neo level increased in (10) day post burn

The Effect of Chronic liver diseases on homocysteine and vitamin B12 in patients serum

Background: Homocysteine (Hcy) is a sulfur containing amino acid that is formed as an intermediary in methionine metabolism. Raised plasma homocysteine levels, which may contribute to the increased risk of chronic liver disease. Patients and Methods: Sixty two patients with chronic liver disease and 26 healthy individuals were included as normal controls for the study. The HPLC system was used for the determination of Hcy and vitamin B12. Results: A highly significant Hcy concentrations were noted in all patients with cirrhosis, chronic hepatitis or liver mass. There was a trendency towards higher Hcy concentrations in more advanced stages of liver disease. The study showed that the concentrations of total Hcy were significantly higher in the patients than in the normal control group, irrespective of the age or gender. Mean serum concentration of vitamin B12 were significantly increased in cirrhotic patients and those with liver cancer compared to the control subjects and chronic hepatitis symptomatic patients. Conclusion: The serum levels of both homocystein (Hcy) and vit. B12 were significantly increased in cirrhotic patients and those with liver cancer compared to chronic hepatitis symptomatic patients

Practical Investigation of Effectiveness of Direct Solar-Powered Air Heater

Solar energy is clean and available, and its use doesn\u27t hurt the environment. Heating conditioned homes and offices in wintertime deduct a large part of the amount of fuel consumed for these purposes. The use of solar radiation to heat the air proved its feasibility and usefulness and is in the research and development process and takes many forms. One of the primary types of solar air heaters is solar air heater of a transparent collector. In this study, a transparent collector solar air heater was designed and manufactured with an area of 1 m2. An aluminum plate was used to be the heating source; it takes its heat from the solar radiation. The tests results confirm the validity of this solar air heater type. The temperature of the heated air increased about 101% of the ambient air. The aluminum plate has proven to work as a source of heat
