In Veda, cow’urine was compared to the nectar. In Susrut, several medicinal properties of cow’ urine have been mentioned and are known to cause weight loss, reversal of certain cardiac and kidney problems, indigestion, stomach ache, edema, etc. However, the literature and scripture did not mention the antigenotoxic properties of cow’urine. Methods In the present investigation, the antigenotoxic/ antioxidant properties of cow’ urine distillate and redistillate were studied in vitro. The antioxidant status and volatile fatty acid levels were determined. Actinomycin-D (0.1ol/L) and hydrogen peroxide (150 mol/L) were used for inducing DNA strand break with 0.1% DMSO as negative control. Dose for the antigenotoxic effect of cow’ urine was chosen from the dose response study carried out earlier. Results Both actinomycin-D and H2O2 caused statistically significant DNA unwinding of 80% & 75% respectively (P<0.001) as revealed by fluorimetric analysis of DNA unwinding (FADU), and the damage could be protected with the redistilled cow urine distillate (1, 50 & 100 ) in simultaneous treatment with genotoxic chemicals. Conclusion The redistillate of cowurine was found to possess total antioxidant status of around 2.6 mmol, contributed mainly by volatile fatty acids (1500 mg/L) as revealed by the GC-MS studies. These fatty acids and other antioxidants might cause the observed protective effects.展开更多

Resistin serum levels are elevated in end-stage renal diseases of people having an increased risk of infections as a result of impaired polymorphonuclear leukocytes (PMNLs) functions. Objectives: To evaluate neutrophil functions (phagocytosis and oxidative burst) in children with end-stage renal disease (ESRD) on regular hemodialysis and to shed light on the contribution of resistin on neutrophil functions. Patients and Methods: The study included 40 children with ESRD on regular hemodialysis. Their ages ranged from 6 to 12 years, and they were selected from children attending the pediatric hemodialysis unit of AL-Zahraa Hospital, Al-Azher University during the period from October 2012 to December 2013. Another group of 40 apparently healthy children with matched age and sex with the patient group served as a control. Serum resistin, phagocytic index and nitro blue tetrazolium test (NBT%) were assessed in both groups. Results: There was a statistically more significant increase in resistin serum levels in cases than in controls;it was (3.25 ± 0.86 ng/ml) and (0.25 ± 0.16 ng/ml) respectively展开更多

Apoptosis occurs in from 20% to 30% of neutrophils over 24 hours of culture in vitro and the addition of G-INH to the medium causes a dose-related increase in the incidence of apoptosis. Heating G-INH at 60t for 30 minutes does not destroy its capacity to induce apoptosis but GM-CSF, G-CSF, and to a lesser extent IL-1β, antagonize this action. IL-3 does not diminish G-INH induced apoptosis of neutrophils. Substances, released from, mature neutrophils may participate in regulating the survival of other neutrophils, particularly in sites where the cells are in close proximity as in the marrow. Self destruction of post-mitotic neutrophils in marrow may thus represent an-other level at which regulation of cell production展开更多

Methods： In a total of 4 265 randomly collected patients attending the andrological outpatient clinic of the Center for Dermatology and Andrology, University of Giessen, Germany, ejaculate volume, pH-value, sperm concentration, total and progressive sperm motility, concentration of polymorphonuclear （PMN） elastase, number of peroxidase-positive cells and fructose were measured and correlated with patient＇s age. Results： While ejaculate volume, motility and fructose all correlated negatively with age, sperm concentration, PMN elastase and the pH-value showed a positive correlation. The prevalence of male genital tract inflammation （as defined by PMN elastase 〉 250 ng/mL） and its severity increased significantly. PMN elastase did not correlate with sperm motility. Fructose as a marker of seminal vesicle function showed a significant negative relationship with the PMN elastase levels, the number of peroxidase-positive cells and sperm motility. Conclusion： The significant increases of PMN elastase levels as marker of male genital tract inflammation in older men appear to be indicative of age-related changes in local immunoregulatory mechanisms. Because there is no association of PMN elastase with sperm motility, a direct inhibitory effect of this enzyme can be excluded.展开更多
