Degree Of Severity

Background: The prevalence of varicose veins of small pelvic veins in women of reproductive age varies widely – from 5.4 to 80 %, due to the low specificity and low sensitivity of clinical diagnostic techniques, and the absence of biomarkers that can be used to identify the formation and progression of varicose veins of small pelvic veins in women.Aims: To identify changes in the levels of parameters of the system “lipid peroxidation – antioxidant protection” with the development of varicose veins of the pelvis in women, as well as the possibility of their diagnostic use.Materials and methods: We examined 200 women with clinical signs of varicose veins of small pelvis. Control group included 30 women without any pathology of venous system. Treatment group included 137 women with varicose veins of small pelvis: with mild degree of severity – 39 women, with moderate degree of severity – 65 women, with severe degree of severity – 33 women. We performed comparative analysis of lipid peroxidation – antioxidant defense system in women with and without varicose veins of small pelvis taking into account the severity degrees of pathological process.Results: We obtained the most informative indices for lipid peroxidation – antioxidant defense processes in blood of women with varicose veins of small pelvis: concentration of diene conjugate (DC) for the mild degree of severity of pathological process, lipid hydroperoxide (LHP), DC and malonic dialdehyde (MDA) – for the moderate and severe degree of severity, and also changes in the activity of antioxidant enzymes with increase of the severity of the disease. Assessment of the level of catalase (Cat) and glutathione peroxidase (GP) showed their highest informative value at the mild degree of severity. Concentrations of glutathione reductase (GR), glutathione S-transferase (GST) and reduced glutathione (GSH) are more statistically significant markers for severe forms of pathological process.Conclusions: Our research showed the relevance and advisability of the studying the levels of lipid peroxidation – antioxidant defense indices in women with varicose veins of small pelvis. We registered the highest diagnostic value of DC, Cat and GP in the beginning of the disease and of LHP, DC, MDA, GR, GST and GSH – at severe forms of the pathological process. We obtained reference values for DC, MDA, Cat, SOD and GP concentration that can be considered as the predictors of the development of varicose veins of small pelvis.

Present investigation was focused on the response and regulation of the antioxidant defense system and photosynthetic pigment variation effect of two important fungicides or plant growth regulators Hexaconazole (HEX) and Tebuconazole (TBZ) on drought stressed tomato (Lycopersicon esculentum Mill.) plants. Drought stress was imposed for 30 Days after sowing (DAS) of tomato plant. The water was irrigated by 4 Days Interval Drought (DID) and the control plants were regularly irrigated. Triazole treatment like HEX at 15 mg L-1 and TBZ at 10 mg L-1 imposed on 30, 40 and 50 DAS. The plant samples were collected on 40, 50 and 60 DAS. The photosynthetic pigments like chlorophyll – a, chlorophyll – b and total chlorophyll were estimated. The drought stress reduced the photosynthetic pigments and increased the antioxidant contents and antioxidant enzymes activities. The combined drought stress with triazole treatments increased the photosynthetic pigments then reduced the ascorbic acid (AA), α-tocopherol, catalase (CAT), peroxidase (POX) and superoxide dismutase (SOD) activities, when compared to drought stressed plants. It can be concluded that the triazole treatment partially mitigated the adverse effects of drought stress in L. esculentum.
