RESUMEN

Goldenberry (GB) is a promising fruit that can be a constituent in many possible nourishments. No notifications were obtained regarding the impact of exposure to goldenberry extract in the viewpoint of blood rheological properties as well as erythrocyte osmotic fragility of red blood cells (RBCs) in obese rats. A substantial reduction in plasma triglyceride, total cholesterol, and LDL, with a considerable increment in HDL levels relative to the obese group (p ≤ 0.05), was observed in rats receiving low and high doses of GB, accompanied by restoration of SOD activity and GSH levels. Rheological parameters of rats' blood have been studied over a wide range of shear rates (225-1875 s-1). A significant decrease in blood viscosity in rats who received low and high doses of GB extract was compatible with every shear rate compared to the control group. The shear stress values of the obese rats reduced appreciably (p ≤ 0.05) in all values of shear rate (from 75 to 500 s-1) proportional to the control group, while in the groups that received low and high doses of GB extract, shear stress was restored to the control values. Finally, administration of GB extract significantly decreased yield stress and indices of whole blood aggregation, with an extremely substantial increment in flow rate, in rats given low or high doses of GB compared to obese ones. The result also showed a decrease in both the average raised osmotic fragility and the hemolysis rate in rats after supplementation with low and high doses of GB extract.

RESUMEN

BACKGROUND AND OBJECTIVE: The laser acupuncture has many potential therapeutic effects. Currently, they are not evaluated for their therapeutic effects on rheumatoid arthritis (RA) patients. The aim of this study was to investigate the effects of laser acupuncture on the oxidative and antioxidative markers, as well as the inflammatory markers and disease activity of RA patients. DESIGN/MATERIALS AND METHODS: The study was conducted on 30 RA patients and 20 healthy subjects. The patients were subjected to laser acupuncture (904 nm, 100 mW power output, 1 minute irradiation time, beam area of 1 cm(2) , total energy per point 6 J, energy density 6 J/ cm(2) , irradiance 0.1 W/cm(2) , frequency 10000 Hz, duty-cycle 100%) for 3 days/week for duration of 4 weeks. The acupuncture points of exposure were LI4, TE5, LI 11, DU 14, LIV3, SP6, GB34, and S36. The levels of oxidative and antioxidant markers were determined by spectrophotometric methods whereas the inflammatory markers were determined by ELISA methods. Lastly, using DAS28 scores the disease activity was assessed. RESULTS: After laser acupuncture, the study group revealed significantly increased plasma superoxide dismutase (SOD), glutathione reductase (GR), catalase activities, blood glutathione (GSH), and plasma ATP concentrations, compared to those before treatment (P < 0.0005). Moreover, the results revealed significantly reduced plasma malondialdehyde (MDA), serum nitrate and nitrite, serum C-reactive protein (CRP), plasma interleukin-6 (IL-6) levels and significantly reduced glutathione peroxidase (GPx) activity and erythrocyte sedimentation rate (ESR) in laser exposed patients, compared to those before treatment (P < 0.0005). The RA patients subjected to laser acupuncture showed highly significant reduction in disease activity (P < 0.0005) based on DAS28 score. CONCLUSION: Our study results confirmed the effectiveness of laser acupuncture in alleviating oxidative stress and inflammation, improving antioxidant and energy metabolic status, while also suppressing the disease activity in RA patients. Laser acupuncture is a promising treatment modality to reduce the pain and suffering of RA patients because of its efficiency in inhibiting most of the main factors involved in the pathogenesis of this disease.

RESUMEN

The levels of the inactive hemoglobin (Hb) pigments [such as methemoglobin (metHb), carboxyhemoglobin (HbCO) and sulfohemoglobin (SHb)] and the active Hb [in the oxyhemoglobin (oxyHb) form] as well as the blood Hb concentration in healthy non pregnant female volunteers were determined using a newly developed multi-component spectrophotometric method. The results of this method revealed values of SHb% in the range (0.0727-0.370%), metHb% (0.43-1.0%), HbCO% (0.4-1.52%) and oxyHb% (97.06-98.62%). Furthermore, the results of this method revealed values of blood Hb concentration in the range (12.608-15.777 g/dL). The method is highly sensitive, accurate and reproducible.
