This work demonstrated the immunological and antioxidant activities of Thaumatococcus daniellii leaf extracts and their potential as the pharmaceutical factor for the treatment of some pathological disorders such as cancer, leucopenia, cells inflammation, dietary, atherosclerosis, neurodegenerative disease and other immunological and oxidative stress disorders.36 albino rats of average weight 140 ± 5 g were randomly grouped into 6 with six rats per group. The rats in group A (positive control) received only 0.1% DMSO. The rats in the negative control (group B) received pyrogallol (immunosuppressor) + 0.1% DMSO for 7 days and challenged with 0.1ml Sheep Red Blood Cell (SRBC). The test groups (C to F) also received pyrogallol + 0.1% DMSO for 7 days and were also challenged with SRBC for a period of 72hours after which they were treated with High and Low doses of either petroleum ether or water extracts of Thaumatococcus danielii for 21days. The assessment of immunomodulatory activity was carried out using Carbon Clearance Test. Haematological/ immunological parameters, Spleen and Plasma antioxidant parameters like Catalase (CAT), Superoxide dismutase (SOD), Glutathione Peroxidase (GPX) Activities, Lipid Peroxidation (LPO) and Malonaldehyde (MDA) concentrations were also determined. Result unveiled a significant (p<0.05) increase in the phagocytic index of both high doses of water and petroleum ether extracts compared to the negative control group. There were no significant (p<0.05) changes in the Heamatological parameters and plasma catalase, but there was a significant change in the white blood cell (WBC) count and also an improvement in the spleen and plasma antioxidant parameters. Further study is required to understand the mechanism of action of both extracts in order to exploit it in immunomodulation.

Abstract The haemato-biochemical indices and oxidative stress markers in horses naturally infected with Trypanosoma evansi were evaluated by analyzing the level of these parameters between T. evansi infected (microscopically positive patent group and PCR positive latent group) and infection free horses. To compare the hemato-biochemical indices and oxidative stress indicators, horses were divided into three categories based on diagnostic test employed and positive results obtained. These included Romanowsky stained slide positive group (Group I; n = 6), PCR positive group (group II; n = 28) and negative control group (group III, n = 30), revealing parasitologically positive patent, molecular positive latent and disease free status of horses. A significant reductions in total erythrocytes count (TEC, P = 0.01), haemoglobin (Hb, P = 0.01) and packed cell volume (PCV, P = 0.04) was noticed both in group I and group II while significant neutrophilia and lymphocytopenia was observed in group I when compared to negative control group. Substantial increase in creatinine (CRTN, P = 0.032) and gamma glutamyl transferase (GGT, P = 0.012) in group I while significant decrease in glucose (GLU, P = 0.04) and iron (Fe, P = 0.01) were noticed in both group I and group II in comparison to group III. A significant difference in lipid peroxides (LPO, P = 0.01) with highest level in patent group I (15.33 ± 0.53) followed by PCR positive latent group (14.09 ± 1.66) indicates higher lipid peroxidation in erythrocytes and oxidative stress in decreasing order when compared with infection free control horses (9.83 ± 0.97). Catalase (CAT, P = 0.01) was significantly lower in parasitological (0.82 ± 0.14) and molecular positive cases (1.27 ± 0.35) in comparison to control group (3.43 ± 0.96). The levels of superoxide dismutase (SOD, P = 0.01), reduced glutathione (GSH, P = 0.01) and ferric reducing antioxidant power (FRAP, P = 0.01) were significantly lower in parasito-molecular positive cases as compared to infection free control horses. An inverse correlation of RBC count with LPO and GSH and a direct correlation with catalase, SOD and FRAP was revealed. Overall, the observed substantial decreases in the oxidative parameters like catalase CAT, SOD, GSH and FRAP activities with remarkably elevated levels of LPO indicate high exposure of erythrocytes to oxidative damage in T.evansi infected horses.

Abstract Hypertension presents one of the main risk factors for cardiovascular diseases which are the leading cause of morbidity and mortality worldwide. Structural and mechanical changes of the heart and blood vessels as well as overproduction of reactive oxygen species may occur due to the increased blood pressure. Therewith, the goal of our study was to estimate the effects and duration of swimming as a possible therapy approach on blood pressure and oxidative stress parameters in normotensive and hypertensive rats. The study was conducted on 60 male Wistar albino rats divided into two groups, normotensive and hypertensive rats. Each of these groups was divided into three subgroups according to the swimming protocol. The swimming training was kept constant (60 min/day, for five days a week) with two days of rest. After six or nine weeks of the swimming protocol, blood pressure and oxidative stress markers were measured. The control group rats were put in water for one minute a day, in order to avoid water-induced stress. Training significantly reduced systolic blood pressure in hypertensive rats, while diastolic pressure did not change in the group that swam six or nine weeks. The results showed that swimming increases the activity of all measured antioxidative parameters, while values of prooxidants varied depending on the training protocol. Our results confirmed that swimming, as an aerobic exercise, decreases blood pressure and has time-dependent positive system adaptations, especially on the antioxidant parameters.

Background: The chemotherapeutic use of cisplatin (CP) is restricted because of its hepatotoxicity induced by oxidative stress. Malondialdehyde (MDA) is a secondary product of lipid peroxidation as a biomarker of oxidative stress. Individual administration of black seed oil (BSO) or honey (H) demonstrated hepatoprotective effect in rats. Interaction of both substances when administrated as combination can be evaluated using combination index (CI) to quantitatively depict synergism (CI<1), additive (CI=1) and antagonism effect (CI>1). Objective: to know the combination effect of BSO and honey on rat liver tissue given CP exposure. Methods: This study used 30 rats were divided into 10 groups. Normal group (N); Negative control group (NC); P1-P4 groups were administerated BSO (1 and 2 mL/kg) and honey (3.7 and 7.4 mL/kg); P5-P8 groups were combination of BSO and H. P1-P8 groups were given BSO and honey orally for 21 days. On the 18th day, NC and P1-P8 groups were given CP 8 mg/kg intraperitoneally, while the N group was given NaCl 0.9% 1 mL/kg intraperitoneally. Result: Malondialdehyde (MDA) levels were found to be lower in P1-P8 groups compared to negative control group and P6 and P7 groups have levels equivalent to MDA levels of normal control group (p > 0.05). Conclusion: Combination of BSO and honey provides a protective effect on cisplatin-induced rat liver tissue damage indicated by reduced MDA levels, but all combination group showed antagonism effect.

Aim: This study evaluated the effects of metformin in combination with a herbal capsule (glucoblock) on insulin resistance and oxidative stress index in type 2 diabetic rats. Methodology: A total of 35 male Wistar albino rats weighing between 120-220 g were used for this study. The rats were placed on high fat diet, and diabetes was induced by a single intraperitoneal injection of freshly prepared streptozotocin (STZ) (45 mg/kg body wt). Fasting plasma glucose (FPG) was determined using the glucose oxidase method. Fasting plasma insulin (FPI), total oxidant status (TOS), total antioxidant status (TAS) and superoxide dismutase (SOD) levels were quantitatively determined by a rat-specific sandwich-enzyme linked immunosorbent assay (ELISA) method. Insulin resistance (IR) was determined using the homeostatic model assessment for insulin resistance (HOMA-IR) method. Oxidative stress index (OSI) was determined by the ratio of TOS to TAS. Phytochemical analysis on the herbal capsule was done using classical methods. Results: The results revealed the presence of alkaloids (100.31μg/mg), flavonoids (131.45μg/mg), cardiac glycosides (55.93μg/mg) and saponins (61.47μg/mg) in the herbal drug glucoblock. The results showed significantly lower FPG levels in the treatment groups when compared to the diabetic control. Group 3 administered metformin had significantly higher FPG levels compared to the negative control. Group 4 administered the herbal drug glucoblock and group 5 administered a combination of metformin and glucoblock, showed no significant differences in FPG levels when compared to the negative control. The diabetic control had significantly higher FPI levels compared to the negative control and treatment groups. The treatment groups showed no significant differences in FPI levels when compared to the negative control. HOMA-IR was significantly higher in the diabetic control compared to the negative control and treatment groups. Also, HOMA-IR values in the treatment groups showed no significant difference compared to the negative control except for group 3 (metformin), that was significantly higher than the negative control. SOD was significantly lower in the diabetic control, compared to the negative control and treatment groups. There were no significant differences in SOD levels in the treatment groups compared to the negative control. TOS levels in the negative control group and treatment groups were significantly lower, compared to the diabetic control. TAS was significantly lower in the diabetic control and treatment groups compared to the negative control. OSI in the diabetic control was significantly higher, compared to the negative control and treatment groups. Also, the treatment groups had significantly higher OSI compared to the negative control. Conclusion: High fat diet and streptozotocin induction produced significant insulin resistance and oxidative stress in the diabetic rats. Glucoblock was more effective in reducing insulin resistance compared to metformin. The combination showed synergistic drug-herb reaction as glucoblock potentiated the actions of metformin. Both showed antioxidant potential but were not effective in lowering oxidative stress to normal levels. There is need to incorporate antioxidant therapy in the treatment protocol for diabetes mellitus.

Abstract Doxorubicin is a chemotherapeutic agent known to cause cardiotoxicity that is thought to be associated with oxidative stress. The aim of the current study is to investigate the role of grape polyphenols’ antioxidant property as cardioprotective against doxorubicin-induced cardiotoxicity. Adult Wistar rats weighing 200 ± 20 g were divided into 3 different groups: a doxorubicin group that received a single intraperitoneal administration of doxorubicin (8.0 mg/kg body weight), an experimental group that received doxorubicin and grape polyphenol concentrate (25 mg/kg) via intragastric route, and the third group was a negative control group that received water only. On day 8, blood samples and tissues were harvested for analyses. The results indicated that grape polyphenol concentrate was able to reduce the signs of cardiotoxicity of doxorubicin through the reduction of aspartate aminotransferase activation, increasing the plasma antioxidant levels and decreasing the level of free radicals. The results also showed that grape polyphenol concentrate was able to reverse doxorubicin-induced microscopic myocardial damage. The myocardial protective effect of grape polyphenol might likely be due to the increase in the level and activity of the antioxidant enzymes, superoxide dismutase, catalase, and glutathione peroxidase. In conclusion, grape polyphenol concentrate displayed cardioprotective effect and was able to reverse doxorubicin-induced-cardiomyopathy in experimental rats.

AbstractThe present investigation evaluates the neuroprotective effect of chlorogenic acid (CA) in alcohol-induced brain damage in neonatal rats. Ethanol (12 % v/v, 5 g/kg) was administered orally in the wistar rat pups on postnatal days (PD) 7-9. Chlorogenic acid (100 and 200 mg/kg, p.o.) was administered continuously from PD 6 to 28. Cognitive function was estimated by Morris water maze (MWM) test. However, activity of acetylcholinesterase, inflammatory mediators, parameters of oxidative stress and activity of caspase-3 enzyme was estimated in the tissue homogenate of cerebral cortex and hippocampus of ethanol-exposed pups. It has been observed that treatment with CA attenuates the altered cognitive function in ethanol-exposed pups. There was a significant decrease in the activity of acetylcholinesterase in the CA treated group compared to the negative control group. However, treatment with CA significantly ameliorates the increased oxidative stress and concentration of inflammatory mediators in the brain tissues of ethanol-exposed pups. Activity of caspase-3 enzyme was also found significantly decreased in the CA treated group compared to the negative control group. The present study concludes that CA attenuates the neuronal damage induced in alcohol exposed neonatal rat by decreasing the apoptosis of neuronal cells.

Traditional alcoholic drinks are made traditionally or conventionally and simply packed. One of the traditional alcoholic drinks in Indonesia and commonly consumed is Tuak (Palm wine). Several indigenous communities in Lombok have fermented drinks popularly known as Tuak or Arak. Palm sap which is the basic ingredient in making palm wine containing alcohol. The most common liver diseases due to alcohol abuse include fatty liver, alcoholic hepatitis and liver cirrhosis. Ethanol metabolism in liver cells can cause an increase in the production of free radicals with various mechanisms so that oxidative stress will damage liver tissue. The supply of pineapple can prevent and repair liver damage due to oxidative stress processes, especially those caused by alcohol. Markers of liver damage are SGOT and SGPT enzymes. This research is a true experiment. The total number of experimental animals used was 21 individuals, negative control rats were only given standard feed, positive control rats were given palm wine without pineapple extract and treatment group were given palm wine and pineapple extract. Palm wine and pineapple were given together with standard feed for 14 days and on day 15th, the blood of the rats was taken to check the levels of SGOT and blood SGPT. The results showed the average SGOT enzyme levels in the negative control group 117.85 U / L, in the positive control group 126.14 U / L, and the treatment group 110.71 U / L. ANOVA test shows SGOT levels of white rats have significant differences in the experiments conducted (p <0.05). Examination of SGPT enzyme levels in the negative control group obtained an average yield of 25.42 U / L, positive control 30.42 U / L, and treatment 29.14 U / L. The ANOVA test results of SGPT levels in white rats show significant differences in the experiments conducted (p <0.05).
