Background: Physical exercise is essential for performance of the immune system. The integrity of immune response is dependent on the intensity and duration of the exercise performed. During exercise the metabolic and hormonal changes that occurred can induce lymphocyte apoptosis. Dehydroepiandrosteron sulphate (DHEAS) is one of the hormones that is affected by exercise, it is an androgen released from the adrenal cortex in response to adrenocortiocotropin releasing hormone (ACTH). DHEAS is regarded as an anti-aging hormone; it is primarily immune enhancing, providing some degree of counterbalance to the potentially detrimental effects of catecholamine and cortisol which are immunosuppressive if chronically elevated, it also had a role in the elimination of harmful lymphocytes which may give rise to chronic inflammation and possibly to autoimmunity.
Methods: Sixty healthy subjects were involved in this study with a mean age of (37.05 ± 13.02) year. They were subjected to moderate exercise session which lasted for 60 min and repeated 3 times per week for 3 months. The exercise intensity was 50-60% of heart rate reserve (according to Karvonen formula). Two exercise stages were performed; the first stage include 30 minute of physical activity program and the second stage include 30 minute of treadmill exercise. Blood samples were collected before and after exercise to examine its effect on the level of DHEAS hormone and apoptosis of peripheral blood lymphocyte.
Results: This study showed significant increment (P < 0.05) in the level of DHEAS hormone and the percentage of lymphocyte apoptosis after exercise in comparison to pre exercise values for each week along the period of the test.Three months exercise showed a significant correlation with the levels of DHEAS hormone (P= 0.000, r= 0.75), and with percentage of lymphocyte apoptosis (P = 0.001, r= 0.701).
Conclusion: in this prospective study, following moderate exercise for three months; there was increase in the percentage of periphral blood lymphocyte apoptosis and increased level of DHEAS hormone in the first two months while in the third month this anti aging hormones had reached to a steady state after the subjects get trained to exercise.
Background: Growth hormone is a hormone responsible for the normal body growth and development by stimulation protein production in muscle cells and
energy release for breakdown of fat. On the other hand leptin is a newly discovered hormone that is mainly synthesized in adipose tissues it decreases food intake by
causing satiety and promoting energy combustion . Both aging and obesity are associated with a reduction in growth hormone secretion. In the mean time obese
humans have increased circulating leptin.
Objective: The aim of this paper is to shed light on the contribution of these two hormones in the mechanism of aging process in an attempt of improving this
process for a better life at old ages.&n
Background:
Background: Mitochondria play an important role in the regulation of physiological type of cell death (Apoptosis) this type of cell death can be stimulated by two major pathways: external (Fas-Fas ligand interaction) and internal mitochondrial pathway which require disruption of mitochondrial transmembrane potential (ΔΨm ) which leads to opening of mitochondrial channels that lead to release of cytochrome –C which would execute apoptotic process.
Patients and Methods:The study included 32 normal subjects; 2 ml of venous blood were aspirated from each of them and processed for peripheral blood lymphocytes separation (PBL)
Then lymphocyte apoptosis was studied before and after exposing (PBL) to hypertherm
Background: Bicycling is a type of aerobic exercise that it is beneficial for the health of cardiovascular, pulmonary, and musculoskeletal systems .In this study, utilization of some of electrophysiological tests is to assess changes , from the functional point of view, in the peripheral nerves & their muscles that occur in relation to maximal exercise.
patients & methods: 100 young healthy males , age (18-35) years old, were collected during the period from 1st of April to 1st of October 2008 at the department of neurophysiology in the Ibn Sinna teaching hospital , Mosul city. They underwent electroneurographic assessment of common peroneal & tibial nerves, in addition to electromyographic as
Back ground: The epidemic of obesity is a major health problem in the developed world with a great influence on morbidity and mortality.
The aim of study: to evaluate serum ghrelin levels achieved through LSG and on insulin resistance and the serial changes of insulin concentration in obese patients following gastric sleeve.
Patients and methods: twenty four patients underwent LSG with 25 controls were selected. Body mass index (BMI), waist circumference (WC), lipid profile, fasting blood sugar (FBS), glycated hemoglobin (HbA1c), fasting insulin, QUICKI and ghrelin hormone concentrations were measured for controls and patients prior LSG, then one month and three months post-surgery.
Results: A significant decline was noticed in
The bioequivalence of a single dose tablet containing 5 mg amlodipine as a test product in comparison to Norvasc® 5 mg tablet (Pfizer USA) as the reference product was studied. Both products were administered to twenty eight healthy male adult subjects applying a fasting, single-dose, two-treatment, two-period, two-sequence, randomized crossover design with two weeks washout period between dosing. Twenty blood samples were withdrawn from each subject over 144 hours period. Amlodipine concentrations were determined in plasma by a validated HPLC-MS/MS method. From the plasma concentration-time data of each individual, the pharmacokinetic parameters; Cmax, Tmax, AUC0-t, AUC0-
Background: Determine how do obesity and type2 diabetes intertwined? and what it takes to turn an obese person into a person with diabetes. That link may help to understand why some obese people never develop diabetes while many others do. Serum sugar level was used as indicator of insulin level; leptin level was used as indicator of leptin resistance.
A total of 50 obese subjects were involved in this study, 25 obese subject (BMI >30) had diabetes mellitus type 2(no insulin dependant), selected from Baghdad teaching Hospital in Baghdad /Iraq. The remaining 25 obese (BMI >30) were normal healthy individuals.
Patients and Methods: ELSA technique was used for the measurement of serum leptin. Blood
The aim of this study was intended to study the effect of rifampicin in the level of thyroid's gland hormones (T4 ØŒT3) and thyroid -stimulating hormone (TSH) in rabbits. Eight male rabbits were used through out this study, their weights were measured before the starting of the experiment. Animals were divided into two groups (each group contains 4 rabbits), the first group was administrated daily with 15 mg/Kg physiological normal saline for 35 days and used as a control group, while the second group was administrated with 15 mg /Kg daily for 35 day of rifampicin capsule 300 mg. At the end of the experiment, all of animal groups were
... Show MoreThe objective of the present study was to investigate the effect of body mass index (BMI) on semen parameters, level of sex hormone and sperm DNA integrity. Semen samples were collected from (85) infertile men and (40) healthy fertile men with range of age (38.191 ± 0.84) years during their attendance at High Institute of Infertility Diagnosis and ART, Al-Nahrain University from March to June 2016. Semen samples were obtained by masturbation after 72 hours of abstinence. Seminal fluid analyses included semen volume, sperm concentration, percent sperm motility, percent sperm morphology, and sperm chromatin integrity DNA fragmentation index (DFI]). Serum samples were collected from each subject for determination the level of Follicle Stim
