BACKGROUND: Considering the negative influence of a visceral obesity on spermatogenesis, it is important to investigate its pathogenetic factors. AIMS: To reveal the pathogenetic factors of disorders in spermatogenesis and antioxidative activity of an ejaculate in young men with post pubertal visceral obesity and normal andrological anamnesis. MATERIALS AND METHODS: 47 men under 30 years with post pubertal and nutritional visceral obesity have been included into one-stage research. The length of circle of waist, lipid blood spectrum, blood levels of glucose and insulin, antioxidant activity and electronic-microscopic analysis of an ejaculate have been examined. Differences were considered statistically significant with p 0,05. RESULTS: The LDL and triglyceride levels in patients with disorders in spermatogenesis were significantly higher than considered in men with normozoospermia. Correlations between antioxidative activity of ejaculate and levels of LDL (n=47, r=-0,310; p=0,033), triglyceride (n=47, r=-0,366; p=0,011) and the number of normal spermatozoons in ejaculate (n=47, r=0,343;p=0,017) have been revealed. CONCLUSIONS: The dyslipidemia in young men with post pubertal visceral obesity and normal andrological anamnesis can be considered as pathogenetic factors of disorders in spermatogenesis. Nevertheless the dyslipidemia can influence spermatogenesis through oxidative stress.

Background: Taking into account a common development of a visceral obesity at men, research of its influence on a spermatogenesis and antioxidative activity of an ejaculate is actual. Aims: Assessments of spermatogenesis and antioxidative activity of ejaculate in young men with post pubertal visceral obesity and normal andrological anamnesis in comparing with healthy men. Materials and methods: 80 men with post pubertal and nutritional visceral obesity in the age of until 30 years and 30 healthy men have been included in cross-section research. The assessments of waist circumference, levels of gonadotropins and total testosteron, antioxidant activity of an ejaculate, its electronic-microscopic examination was carried spent. Statistically significant counted differences between groups at p 0.05. Results: In young men with post pubertal visceral obesity and normal andrological anamnesis the spermatogenesis was significantly worse in comparing with healthy men. These differences were were significant for waist circumference more more then 98 cm. Antioxidative activity of ejaculate in men with visceral obesity also was significantly lower in comparing with healthy men. The maximal expressiveness of sperm pathogenetic disorders was in men with waist circumference more then 102 cm. Conclusions: In young men with post pubertal visceral obesity and normal andrological anamnesis the spermatogenesis is worse compared to healthy men. If the waist circumference less than 102 cm, the spermatogenesis is normal in most cases, but antioxidant activity of an ejaculate is pathological and mediated through oxidative stress.

Introduction. Given the frequent development of visceral obesity in men, it is important to study its effect on spermatogenesis. Aim. Assessment of the structure of pathozoospermia in young men with post-pubertal visceral obesity and a non-aggravated andrologic anamnesis. Materials and Methods. In a single, one-stage study, 80 men with post-pubertal alimentary visceral obesity aged up to 30 years were included. The length of the circumference of the waist, the level of gonadotropins and total testosterone, the antioxidant activity of the ejaculate, its electron microscopic examination were estimated. Statistically significant differences were considered between groups at p 0.05. Results. 24% of men did not have pathosoospermia. The main pathogenetic phenomenon, revealed in patients with pathozoospermia, was astenozoospermia - 100%. There was also a high prevalence of teratozoospermia - 36%. The prevalence of oligozoospermia was 11% of cases. An increase in the content of spermatozoa with insufficiently condensed chromatin and a decrease in the antioxidant activity of the ejaculate were characteristic of all types of pathozoospermia in obese men. A decrease in testosterone levels was characteristic of oligozoospermia. At the same time, statistically significant negative correlations between waist circumference and testosterone level, quantitative indicators of ejaculate, its antioxidant activity, as well as a positive correlation between the waist circumference and the content of spermatozoa with insufficiently condensed chromatin were established. Conclusions. In young men with post-pubertal visceral obesity and a non-aggravated andrologic anamnesis, the prevalence of pathozoospermia in our study was 76%. The most common was oligozoospermia, which was characterized by the presence of the syndrome of normogonadotropic hypogonadism, which developed in patients with the most pronounced visceral obesity. An increase in the content of spermatozoa with insufficiently condensed chromatin and a decrease in the antioxidant activity of the ejaculate is characteristic of all types of pathozoospermia in obese men, which is due to oxidative stress.

Increased metabolism that occurs during pregnancy can result in oxidative stress which is harmful to cells and, consequently, for the proper functioning of the whole organism. Plasma and recently also saliva are important resources for evaluating physiological and pathological conditions in animals. The study aimed to investigate the influence of the metabolic state on the effectiveness of the antioxidant profile of plasma and saliva during the pregnancy of cows. Seventy-six healthy pregnant and twelve non-pregnant control cows were included in the study. Blood and saliva samples were collected each month of the pregnancy course. Examined body fluids were used to evaluate both the total antioxidant capacity (TAC) and the oxidative parameters related to protein and lipid peroxidative processes. TAC, the content of hydroperoxides, and SH groups were determined spectrophotometrically while formylokinurenine and bityrosine contents were measured spectrofluorimetrically. The results showed dynamic changes depending on the period of pregnancy course. The highest antioxidant activity in plasma was mostly noted in early pregnancy and advanced pregnant cows. All tested parameters except SH groups expressed higher values in saliva compared to plasma. Obtained results reveal that the increase in oxidative intensity induced appropriate answers of cells reflected in the increase in antioxidative activity of the organism. Moreover, some examined parameters can indicate the intensity of oxidative stress and therefore could be used in a panel of markers of the physiological course of pregnancy. However, with regards to antioxidant/oxidative parameters, saliva reflects the content of plasma only in part, due to the local metabolism of the salivary gland. Further studies are necessary to establish physiological ranges of antioxidative/oxidative profiles in cows and to define the usefulness of saliva as biological material in oxidative stress diagnostics.

Free radicals and reactive species are widely believed to contribute to the development of several diseases by causing oxidative stress and eventually oxidative. Vernonia amygdalina (Astereacea) is a small shrub or tree between 1 and 5m high growing throughout tropical Africa. Plants are generally known as bitter leaves is well cultivated and is a general market for merchandise in several countries. The purpose of this study was to determine the antioxidant activity of hexane fraction from ethanol extract od Frican leaves (Vernonia amygdalina Del.). The method used in this study was the DPPH (1,1-Diphenil-2-Picrylhydrazyl) method. The result of phytochemical screening showed that ethanolic extract of African leaves contained a composition of secondary metabolites of alkaloids, flavonoids, tannins, steroids/triterpenoids and saponins. The antioxidant activity of the extract of n-hexane fraction was classified as very weak with an IC50 value of 317.98 ppm.

Phytochemical composition and antioxidant activity of flowers decoction at post-flowering stage (F3D) of Opuntia dejecta were determined. The obtained findings demonstrate that F3D has a marked antioxidant activity in all tested assays. Furthermore, the present study was designed to test the protective activity of F3D against induced Diabetes type 2 (DT2) in male rats. Those metabolic syndromes were induced by a high-fructose diet (HFD) (10% fructose solution) for a period of 20 weeks. F3D was administered orally (100 and 300 mg/kg body weight) daily for the last 4 weeks. Metformin (150 mg/kg body weight) was used as a standard drug and administrated orally for the last 4 weeks. The results showed a significant increase in blood glucose, triglycerides and hepatic markers (ALAT, ASAT and ALK-P) in HFD group. A significant increase in hepatic TBARS and a significant decrease in SOD, CAT and GPX were observed in fructose fed rats compared to control group. Administration of F3D showed a protective effect in biochemical and oxidative stress parameters measured in this study. Also, oral administration of F3D restored the histological architecture of rat liver in comparison with rats fed HFD. In conclusion, F3D attenuated hepatic oxidative stress in fructose-fed rats.

Phenolic Composition

The genus Cephalaria, belonging to the Caprifoliaceae family, is a rich source of interesting secondary metabolites, including mainly saponins which display a variety of biological activities, such as immunomodulatory, antimicrobial and hemolytic effects. Besides these compounds, flavonoids and phenolic acids were identified in Cephalaria species. Cephalaria is employed in traditional medicine e.g., to cure cardiac and lung diseases, rheumatism, and regulate menstruation. In this review we focus on the phenolic compound composition and antioxidative activity of Cephalaria species. The antioxidant effect can be explained by flavonoids present in all parts of these plants. However, future efforts should concentrate more on in vitro and in vivo studies and also on clinical trials in order to confirm the possibility of using these plants as natural antioxidants for the pharmacology, food or cosmetic industries.
