The present study aims to investigate the effects of duration and complications of type 2 diabetes mellitus on diabetic related parameters, adipocytokines and calcium regulating hormones. This study was conducted on eighty diabetic patients (41 male and 39 female) in Iraq, with an age range of 20-60 years and a disease duration range of 1-180 months. Blood samples were collected from the patients to determine three main types of biomarkers: diabetic-related parameters [Fasting blood sugar is FBS glycated hemoglobin (HbA1c), insulin, and insulin resistance (IR)], adipocytokines [adiponectin and tumor necrosis factor-α (TNF-α), and calcium regulating hormones [parathyroid hormone (PTH), calcitonin, and vitamin D].      The result showed increased levels of some parameters with the increase in duration of disease. Levels of FBS and HbA1c increased significantly (probability <0.05) in the second and the third categories of duration of disease (61-120 and 121-180 month) compared with the first category (1-60 month). Levels of insulin and IR were increased with the increase in duration of disease; this increase was found to be significant (p<0.05) when a comparison was made between the second and the third categories with the first category. Also, a similar trend was observed when a comparison was made between the third category and the second category. There was a significant (P<0.05) increase in the levels of TNF-α and calcitonin in the last category compared with the other categories, and a significant (P<0.05) increase in vitamin D levels in the last category compared with the first category. Non-significant (P>0.05) differences were found in the levels of adiponectin and PTH among all categories of duration of disease.      When a comparison was made between the two groups of patients (with complications and without complications), a significant (P<0.05) increase was found in the levels of FBG, HbA1c, insulin, and IR in patients with complications as compared with patients without complications. A significant (P<0.05) decrease was found in calcitonin levels in patients with complications as compared with patients without complications. Non-significant (P>0.05) differences were found in the levels of the other parameters (adiponectin, TNF-α, PTH and vitamin D) between the two groups of patients.      It can be concluded from the present study that duration of disease affects diabetic related parameters, TNF-α and some calcium regulating hormones (calcitonin and vitamin D), while complications of disease affect diabetic related parameters and calcitonin. It can be suggested that the duration of diabetes is one of the strongest determinants of complication risk.

Abstract The current study aims to evaluate levels of metabolic hormones and lipid profile in a sample of growth hormone (GH) deficient patients. Seventy five GH deficient patients and twenty healthy subjects used as control group have been participated in this study during their attendance to the National Diabetic Center for Treatment and Research/Al-Mustansiriya University. The studied subjects’ ages were with a range (3-15 years). Blood samples were collected from the studied subjects to determine levels of basal GH, GH2 and GH3 after 1 hr and 1/30 hr provocation with clonidine, respectively; insulin like growth factor (IGF-1); levels of metabolic hormones [thyroid profile: triiodothyronine (T3), thyroxin (T4), and thyroid stimulating hormone (TSH)]; and lipid profile [cholesterol, triglyceride, high density lipoprotein (HDL), low density lipoprotein (LDL) and very low density lipoprotein (VLDL)]. The findings of the anthropometric measurements of the studied groups revealed that a non-significant (P>0.05) difference was found in the weight between the patients and the control, while the mean of height in the patients was significantly (P<0.05) lower than its value in the control. Mean of BMI detected a non-significant (P>0.05) difference between the patients and the control. While mean of BMI percentile and mean of BMI Z-score revealed significant (P<0.05) decrease in the patients compared to their values in the control. The results showed that non-significant (P>0.05) difference was found in level of basal GH between the patients and the control, while a high significant (P<0.01) decrease was found in levels of GH2 and GH3 in the patients group compared to the control group. Level of IGF-1 showed a significant (P<0.05) decrease in the patients compared to the control. The results of metabolic hormones revealed a non-significant (P>0.05) difference in serum T3 between the patients and the control, while a high significant (P<0.01) decrease was found in serum T4 in the patients compared to the control.  A non-significant (P>0.05) difference was found in serum TSH between the patients and the control. The data of serum cortisol showed a significant (P<0.05) increase in the patients compared to the control. The results of lipid profile showed a non-significant (P>0.05) difference in serum cholesterol between the patients and the control, while triglyceride showed a significant (P<0.05) increase in the patients compared to the control. A non-significant (P>0.05) difference was found in serum HDL between the patients and the control, while a significant (P<0.05) increase was found in levels of LDL and VLDL in the patients compared to the control. It can be concluded from the present study that diagnosis of GHD cannot be done at the basal serum of GH.  A high level of GH was detected after 1 hr. provocation with clonidine compared with its value after 1/30 hr. provocation. The IGF-1 is an appropriate parameter to expect GHD in children and adolescences whom GHD was detected by GH stimulation testing. Low GH secretion is associated with high level of cortisol resulting in GHD.  Patients with GHD displayed a tendency towards lipids disturbances.

The present study aims to evaluate levels of calcium regulating hormones and some biochemical parameters in a sample of growth hormone (GH) deficient patients. Seventy five GH deficient patients and twenty healthy subjects used as a control group have been involved in this study during their attendance at the National Diabetic Centerfor Treatment and Research /Al-Mustansiriya University. The studied subjects were in an age range of 3-15 years. Blood samples were collected from the studied subjects to determine levels of basal GH,GH 2. and GH 3 after 60 mins. and 90mins. of provocation with clonidine. The study also included the measurement of the levels of insulin like growth factor (IGF-1); calcium regulating hormones [parathyroid hormone (PTH) and vitamin D],and some biochemical parameters [calcium (Ca), phosphorus (P), urea, and creatinine].Distribution of the studied groups according to gender revealed that most of the GH deficientpatients (60 %) were males while 40 % were females,with the difference being statistically significant (P<0.05), while the control included two equal subgroups (50 % males and 50 % females). Distribution of the studied groups according to BMI values showed that the percentage of underweight was significantly (P<0.01) higher in the patients (48%) compared to the control (10%), while the percentage of normal weight was significantly (P<0.01) higher in the control (85%) as compared to the patients (40%).The results showed highly significant decreases (P<0.01) in the levels of basal GH, GH 2 and GH 3 in the patients as compared to the control group. Also, IGF-1 levels showed a high significant (P<0.01) decrease in the patients as compared to the control group.The findings of calcium regulating hormones revealed non-significant differences in the levels of PTH and vitamin D between the patients and the control group. Also, the results of the biochemical parameters (Ca, P, urea, and creatinine) showed non-significant differences in their values between the patients and the control group.It can be concluded from the present study that GH deficiency (GHD) seems to be dominating in the males under weighted patients. The diagnosis of GHD cannot be achieved at the basal GH level.IGF-1 is a reliable marker of GH functions. Finally, levels of calcium regulating hormones are not affected by GHD.

Semen samples of 90 asthenospermic patients were examined, then they were divided into three main equal groups. In the first group, Oxytocin (OT) addition in three concentrations (2, 4, and 6 IU/ml) with sperm preparation medium (SPM) to the semen samples was investigated. Changes in sperm function tests and seminal biochemistry was used as indicator of effect. Results indicated that a significant increase in sperm grade activity in 2 IU/ml OT with a tendency for a decrease in this motility parameter in higher OT concentration. Concentration 2 IU/ml of OT was applied with SPM and without in the second and third groups, respectively. In presence of SPM, a significant increase in the sperm motility characteristics (the percentage of sperm motility and sperm grade activity) was observed. While when SPM was absent, non-significant change in these parameters was seen. These findings indicate that OT at the concentration of 2 IU/ml has got a stimulatory effect on sperm motility characteristics. Using of SPM potentiated this effect of OT.Total protein (TP), cholesterol, calcium, creatine kinase (CK), and fructose were measured in the seminal plasma and in the supernatant of sperm suspension of OT-treated and control samples. According to the results, a high significant increase in cholesterol was found in the external medium, this may be attributed to loss of cholesterol from the plasma membrane of the sperm. Also, OT may modify cellular calcium transport across the plasma membrane, resulting in high intracellular calcium concentration and a high significant decrease in level of calcium in the external medium. In addition to a high significant decrease in fructose level of the external medium.

Background: Many anti-obesity medicines have been increased in recent years to solve the problem of obesity; among these medicines are Green Lean Body Capsules (GLBCs) which contain green plants and fruits extract.Objective: This study was designed to evaluate the effects of daily oral consumption of GLBCs on level of serum lipids, renal function tests, and the histological structure of the kidney in albino rats.Materials and Methods: Twenty adult albino male rats weighing 240-260 g were divided into 2 equal groups: control group and GLBCs-treated group. During the 4-weeks treatment, each rat in the GLBCs-treated group was orally administered with 20 mg/kg B.W. of GLBCs, while the control rats were orally administered with 0.1 ml D.W. Body weights were monitored at the beginning and at the end of the experimental period. Lipid profile [total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), very lowdensity lipoprotein cholesterol (VLDL-C) and low-density lipoprotein cholesterol (LDL-C)], renal function tests (blood urea and serum creatinine) ; in addition to the histological examination of the kidney wereevaluated in all the rats.Results: The results revealed that body weight gain was significantly (P<0.05) less in the GLBCs-treated rats than in the control rats. Results of the lipid profile showed that the levels of TC, TG, LDL-C and VLDL-C were significantly (P<0.05) lower while the level of HDL-C was significantly (P < 0.05) higher in the GLBCs-treated rats than that in the control rats. Regarding the renal function tests, the results revealed that blood urea and serum creatinine levels in the GLBCs-treated rats were significantly (P<0.05) lower than that in the control rats. However, microscopic examination of the kidney revealed that both the control and the GLBCs-treated groups presented similar type of histological manifestations.Conclusion: The data presented in this study suggested that the compounds found in GLBCs may act synergistically to suppress body weight gain, decrease the level of serum lipids, and decrease the level of renal function tests without any histological abnormalities effect in the kidney.
