Introduction. Nowadays, it has been shown that one of the possible ways to increase the effectiveness of the treatment of malignant tumors is the use of combined treatment methods. Aim. To study the intensity of lipid peroxidation (LPO) and the activity of superoxide dismutase (SOD) in hyperthermia against the background of bee venom in the blood of tumor-bearing rats. Materials and methods. The experimental animals were divided into 5 groups: 1st — intact; 2nd — control (tumor-bearing animals (PS-1 tumor strain) with intraperitoneal (IP) administration of saline solution); 3rd, 4th and 5th groups — tumor-bearing animals with IP administration of 0.5 ml of bee venom against the background of hyperthermia 42, 43 and 44°C respectively. The content of diene and triene conjugates, Schiff bases (SB) and SOD activity in the blood of animals was determined. Results. From the 1st day after the end of the experiment, a statistically significant decrease in triene conjugates was recorded in all experimental groups compared to the control group. SB decreased on the 1st–7th day after the end of the experiment with the action of hyperthermia 42°C and bee venom, on the 7th–28th day — with the action of hyperthermia 43°C and bee venom, and on the 28th day — with the action of bee venom and hyperthermia 44°C, which was accompanied by an increase in SOD activity from the 7th day in all experimental groups compared to the control group. Conclusion. Hyperthermia in combination with the action of bee venom causes a decrease in lipid peroxidation products and an increase in antioxidant activity in the blood of tumor-bearing rats. The most effective action, in our opinion, is the use of bee venom against the background of hyperthermia of 43°C, at which a prolonged effect is recorded both with respect to a decrease in the concentration of SB and an increase in the activity of SOD.

ABSTRACT Understanding the physiological defense behavior of plants subjected to herbicide application may help to identify products with higher or lower capacity to cause oxidative stress in crops. This study aimed at evaluating the effect of herbicides in the antioxidant activity of rice plants. The experimental design was completely randomized, with six replications. Treatments consisted of the herbicides bentazon (photosystem II inhibitor; 960 g ha-1), penoxsulam (acetolactate synthase inhibitor; 60 g ha-1), cyhalofop-butyl (acetyl coenzyme-A carboxylase inhibitor; 315 g ha-1) and a control. After the herbicides application, samples of rice shoots were collected at 12, 24, 48 and 96 hours after application (HAA). The components evaluated were hydrogen peroxide (H2O2), lipid peroxidation and activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). Bentazon (up to 24 HAA) and penoxsulam (48 and 96 HAA) reduced the CAT activity. Moreover, these herbicides increased the levels of H2O2, lipid peroxidation and SOD activity, indicating a condition of oxidative stress in rice plants. The cyhalofop-butyl herbicide did not alter the antioxidant activity, showing that it causes less stress to the crop.

The aim of this work was to evaluate the influence of a diet containing 5% dried GP on the antioxidant status (total antioxidant status (TAS), antioxidant enzyme activity (catalase-CAT, superoxide dismutase-SOD, and gluthatione peroxidase-GPx), and lipid peroxidation) on the key organs of the liver, kidneys, and spleen in relation to health status as indicated by blood biochemical parameters and total polyphenol content in the blood, organs (liver, spleen, kidney, mesenteric lymph nodes, heart, and brain) and Longissimus dorsi muscle in piglets. The GP diet results in a significant increase of TAS in the liver, spleen, and kidneys, with increased CAT activity in the spleen and kidneys, increased SOD activity in the liver, kidneys, and spleen, and increased GPx activity in the kidneys, as well as a decrease in lipid peroxidation in the liver and kidneys. The GP included in the piglets’ feed contained polyphenols that showed antioxidant activity and were absorbed in the plasma, contributing to maintaining the good health of the animals. The inclusion of 5% GP inclusion in the diets of piglets is beneficial for overall normal blood constituent metabolism and helps to maintain piglet health by increasing the polyphenol content in blood plasma and antioxidant activity in the liver, spleen, and kidneys.

Evaluation of the phenolic compounds and antioxidant activity ofCedrela odorataL. andJuglans regiaL. bark extracts was performedin vitro.Juglans regiashowed greater extract concentration and higher antioxidant activity. Hypoglycemic activity in rats was assessed by generating a glucose tolerance curve and determining the area under the curve (AUC). Diabetes was later induced by an injection with streptozotocin (65 mg/kg of b.w.) and confirmed after 24 hours. The extract was administered (200 mg/kg b.w.) over 10 days, and blood glucose was monitored and compared with a control group. The glucose AUC showed a hypoglycemic effect ofJ. regiaandC. odoratain normal rats. Both extracts reduced hepatic lipid peroxidation in diabetic rats. Polyphenolic extracts reduced cholesterol levels in a hypercholesterolemic mouse model and decreased hepatic lipid peroxidation. Polyphenolic extract doses of 100 and 200 mg/kg b.w. were administered alone or with cyclophosphamide (CPA) 50 mg/kg ip, which was used as a positive control. Analyses were performed using leukocytes in a comet assay after 4 and 24 h of treatment. Genotoxic effects were evaluated by the comet assay, which showed that whileJ. regiaextract had no effect,C. odorataextract induced slight damage at 200 mg/kg, with the formation of type 0 and 1 comets.

Abstract. Miftahudin, Hasibuan RS, Chikmawati T. 2019. Antioxidant activity of ethanolic extract of three Selaginella species from Java Island, Indonesia. Biodiversitas 20: 3715-3722. Three Selaginella species, S. ornata, S. plana, and S. willdenowii, from Java Island, Indonesia, have been known to have antioxidant properties; however, in vivo antioxidant activities of these species have not been reported. This research aimed to evaluate the in vivo antioxidant activity of ethanolic extract of three Selaginella species. The 70% ethanol extract of three Selaginella species at four different doses was administered to mice one day before being treated with oxidative stress. The liver tissue of mice treated with or without oxidative stress was analyzed their lipid peroxidation by measuring MDA concentration and Superoxide Dismutase (SOD) activities. The results showed that there were variations in antioxidant activity among the three Selaginella species. In general, the dose of 0.3 g extract kg-1 BW has been able to reduce lipid peroxidation and increase SOD activity. The administration of S. ornata extract to the mice at 1.2 g extract kg-1 BW reduced the MDA concentration to the lowest level, but the same dose of two other Selaginella extracts caused toxic effects in mice. The antioxidant activities of S. ornata and S. plana were better than that of S. willdenowii extract, and among those species, S. ornata has the best antioxidant activity.

The vitamin E effect on the lipid peroxidation product content and the endogenous antioxidant activity (at -18 C during the different types of storage) has been studied in goose meat. The goose meat of three samples has been used for storage. Meat of control sample has been obtained from geese fed by the standard diet. The 1st meat test sample of geese differs from the control group by two times higher content of vitamin E (40 mg / kg) in their diet from the 42nd to the 63rd day. Meat of the 2nd test sample obtained from the control group of geese is processed by a vitamin E solution (calculated at 100 mcg per g of meat) immediately before storage. The shelf life of meat is 210 days. It has been established that the intensive accumulation of the secondary lipid peroxidation products begins from the 90th day in the goose meat during its storage. In the goose diet a double increase of the vitamin E has contributed a significant (by 27.6%, p ≤ 0.05) TBA-AP decrease in the first meat test sample in comparison with the control group at the end of the experiment. The addition of vitamin E to the diet of geese has contributed the stabilization of the antioxidant pool in their meat. It has been confirmed by a 1.88-fold lower level of TBA-AP upon initiation of peroxide oxidation of Fe2+ and by the higher coefficient of antioxidant activity (36.0%, p ≤ 0.05) in this sample in comparison with the control on the 210th day. At the end of the experiment, the vitamin E content is higher 41.7 % (p ≤ 0.01) in the first sample than in the control, β-carotene - 15.0 % (p ≤ 0.05), and vitamin A is at the level of the control sample. Processed goose meat with a solution of vitamin E also provides reliable inhibition of peroxidation processes during the first half of the experiment. However, at the end of the experiment the content of TBA-AP reaches the level of the corresponding control indices in the 2nd test sample of meat. From the 120th day, there has been the more intensive use of endogenous antioxidants. The antioxidant activity coefficient decreasing to the control level on the 210th day in this meat sample is its conformation. The meat of this sample differs by a higher content of β-carotene from the control sample significantly (by 13.5%, p ≤ 0.05). Thus, to obtain a prolonged antioxidant effect during low-temperature storage of meat it is more advisable to add vitamin E to the diet of geese in the pre-slaughter period. Key words: geese, meat storage, lipoperoxidation products, antioxidant activity, vitamins E, A, β-carotene.

The present study was conducted to investigate the possible protective effects of lycopene (LC) and ellagic acid (EA) on cyclophosphamide (CP)-induced testicular and spermatozoal toxicity associated with the oxidative stress and apoptosis in male rats. Forty-eight healthy adult male Sprague-Dawley rats were divided into six groups of eight rats each. The control group was treated with placebo; the LC, EA and CP groups were given LC (10 mg kg–1), EA (2 mg kg–1) and CP (15 mg kg–1), respectively, alone; the CP+LC group was treated with a combination of CP (15 mg kg–1) and LC (10 mg kg–1); and the CP+EA group was treated with a combination of CP (15 mg kg–1) and EA (2 mg kg–1). All treatments were maintained for 8 weeks. At the end of the treatment period, bodyweight and the weight of the reproductive organs, sperm concentration and motility, testicular tissue lipid peroxidation, anti-oxidant enzyme activity and apoptosis (i.e. Bax and Bcl-2 proteins) were determined. Administration of CP resulted in significant decreases in epididymal sperm concentration and motility and significant increases in malondialdehyde levels. Although CP significantly increased the number of Bax-positive (apoptotic) cells, it had no effect on the number of Bcl-2-positive (anti-apoptotic) cells compared with the control group. However, combined treatment of rats with LC or EA in addition to CP prevented the development of CP-induced lipid peroxidation and sperm and testicular damage. In conclusion, CP-induced lipid peroxidation leads to structural and functional damage, as well as apoptosis, in spermatogenic cells of rats. Both LC and EA protect against the development of these detrimental effects.

The present study evaluated the therapeutic benefits of complex herbal preparation named CBMDS, consisting of turmeric (Curcuma longa), Boswellia (Boswellia serrata), Methylsulphonylmethane, Devil’s Claw (Harpagophytum procumbens) and Silymarin, using it in combination with methotrexate, in order to suppress adjuvant arthritis in rats, and to attenuate methotrexate-induced liver damage. Adjuvant arthritis was induced in 28 rats by a single subplantar injection of complete Freund’s adjuvant (0.1 mL) into the left hind paw. The animals were divided into four groups (with seven animals in each). Group I received CBMDS, Group II - CBMDS in combination with methotrexate, and Group III just methotrexate. The treatment lasted from day 0 to day 17 (CBMDS was given daily except weekends in a dose of 160 mg/kg, methotrexate - 2 mg/kg once a week). Group IV was the control group. Clinical (body weight, hind paw volume, erythrocyte sedimentation rate, leukocyte count), biochemical (serum pro-/antioxidant activity markers), immunological (serum interleukin levels) and histological changes in joint and liver tissues were evaluated. CBMDS significantly alleviated arthritis and reduced hepatic damage, which was more evident in the methotrexate group. The combined treatment also markedly reduced arthritic symptoms and levels of malondialdehyde. Antioxidant activity was significantly higher in treated Groups I and II. CBMDS and its combination with methotrexate promoted anti-arthritic action, reduced histological changes in the joint tissues, and minimized methotrexate-induced liver toxicity.

The effect of irradiation on oxidants and antioxidants in selected tissues and a possible protective effect of curcumin on these indices were investigated. A total of 28 rats were divided into 3 groups; group 1 was control; group 2 was the irradiation group, saline was administered intraperiotenally (i.p.) for three days and then, 9 Gy gamma irradiation was applied; group 3 was the irradiation + curcumin group: curcumin was given i.p. for three days at 200 mg/kg body weight and then the same dose of irradiation was applied. A significant increase in malondialdehyde (MDA) was detected in the liver, kidney, and brain tissues of the rats as a result of irradiation (P< 0.01). Glutathione peroxidase (GSH-Px) activity in all the tissues (except for kidneys) decreased (P< 0.01), liver SOD (superoxide dismutase) activity decreased (P< 0.05), and GSH (glutathione) levels in kidney and ovary tissues (P< 0.001) significantly increased. While curcumin administration returned the increased MDA levels in the kidneys and brain in result of irradiation to normal (P< 0.01), it did not return the increased MDA levels in the liver tissue to normal (P< 0.001) despite significantly reducing them. While decreased GSH-Px and SOD activity in the liver in result of irradiation increased with the addition of curcumin (P< 0.05), increased GSH levels in the kidneys and ovaries returned to control levels (P< 0.001). When MDA values were examined, it was found that the addition of curcumin protected the liver, kidneys and brain from the oxidative damage caused by irradiation.

In this study, the protective effect of humic substance in the fish feed was investigated against the effects of subletal lead (Pb) concentration on the antioxidant enzyme system in Oreochromis niloticus. For this purpose, the fish which were affected by 1.5 mg/L lead nitrate Pb(NO3)2 medium concentration were fed with feed containing 0.2% of humic substance. Liver samples were taken at 4th and 10th days in this study, which included control group, humic substance (HM), Pb, and Pb + HM groups. The enzyme activity of liver tissue catalase (CAT) and superoxide dismutase (SOD) of O. niloticus and the level of malondialdehyde (MDA), a product of lipid peroxidation, increased significantly at 4th and 10th days in the group with subletal lead concentration compared with the control group. Compared with Pb and HM+Pb groups, it was determined that humic substance application decreased Pb toxicity on lipid peroxidation of liver tissue and did not cause a significant change in CAT and SOD activity. According to the results of the experiment, 0.2% humic substance added to the feed reduced toxicity of subletal Pb concentration on liver tissue lipid peroxidation.

The toxicity of many heavy metals is due to their ability to cause oxidative damage to tissues. Lead is one of the most important metals that pollute the natural environment due to man’s impact The aim of this study is to investigate the potential protective effect of epicatechin alone or combined with lycopene against toxicity of lead in male rats. Five groups of rats were involved in this study; the first was control while the other four injected with lead acetate (100 mg/kg BW) subcutaneous for 2 weeks. On the other hand, the third, fourth and fifth groups were injected with epicatechin, lycopene or epicatechin + lycopene, respectively. Results obtained showed that, the combined treatment (epicatechin + lycopene) exert its effects (100%) against toxic effects against lead by lowering the liver enzymes alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and gamma glutamyle transferase (GGT) activities and decrease lipid peroixdation (MDA) and enhances the superoxide dismutase (SOD) activity. The high-density lipoprotein cholesterol (HDL-c) level was significantly decreased and low-density lipoprotein cholesterol (LDL-c) level was statistically significantly increased in lead-injected rats as compared with control group. The combined treatment with epicatechin and lycopene justify these levels to nearly normal values. The erythrocyte level of total glutathione was decreased in lead-injected rats as compared with control group ( p < 0.001). The combined effect is significantly higher than individual treatment lycopene alone or epicatechin. A negative correlation was found between the blood lead and SOD (r = −0.6) and glutathione (r = −0.81) while a positive correlation with MDA level (r = 0.7).
