The aim of our research was to examine changes in the immune system of the rats influenced by the elevated ambient temperature. Male Wistar rats were divided, into 2 groups and housed at 20 ? 2?C (n=64, control group) and 35 ? 1?C (n=74, experimental group), during precise timing of 1, 4, 7, 14, 21, and 30 days. All the animals were given food and water ad libitum, and were lighted during 12 hours per day. We have measured IgG, IgG1, IgG2a, IgG2b and IgG2c. The obtained results showed significant elevation in the level of IgG after 4 and 7 days (+32%), IgG2a after 7th (+88%), 14th and 21nd day (+110%), IgG2b after 14 days (+60%) at 35 ? 1?C compared with the control group at 20 ? 2?C. IgG1 level was not affected and IgG2c showed significant decrease after 21st day at 35 ? 1?C. In conclusion, during the elevated ambient temperature the immune system is activated as one of the regulation mechanisms in homeostasis and survival of the population.

The effect of strychnine sulfate upon spontaneous locomotor activity in an open field was determined for 20 naive male Wistar rats. The experimental Ss were injected ip with 1.0 cc/kg of a 01% solution of strychnine sulfate in normal saline and the control Ss received a similar injection of 1.0 cc/kg of normal saline. All Ss were given 2 trials 7 days apart in the open field, with the injections preceding the second trial. The behavioral change from Trial 1 to Trial 2 for the control group was compared with that for the experimental group. Strychnine sulfate significantly reduced spontaneous locomotor activity in rats. A significant correlation was found between scores on the first and second trials of the experimental Ss. It was suggested that the concept of “orienting-exploratory behavior” could account for reduced locomotor activity.

Abstract Introduction With glutamine supplementation there is better performance in the body’s defense system. Objective The aim of this study was to analyze the effect of glutamine supplementation on ligand-induced periodontal disease in rats. Material and method 48 selected male Wistar rats were divided into 4 groups (N = 12): control group (CG) including healthy animals receiving daily saline solution via gavage; glutamine group (GG) including healthy animals receiving oral glutamine supplementation by gavage at a dose of 1.5 g / kg / day; periodontitis group (PG) including animals with induced periodontal disease on both upper sides receiving daily saline solution via gavage; experimental group (EG) including animals with induced periodontal disease on both upper sides receiving daily glutamine via gavage at a dose of 1.5 g / kg / day. On the 30th day, all animals were euthanized by excess anesthetic. Result In the various analyses, the EG (116.63 ± 22.50 mm2) compared to the CG (82.32 ± 7.48 mm2) obtained a p<0.05. The PG (143.15 ± 35.24 mm2) compared to the EG group (116.63 ± 22.50 mm2 ) presented a p<0.05. The PG (143.15 ± 35.24 mm2) compared to the CG (82.32 ± 7.48 mm2) presented a p<0.05. The GG (118.09 ± 10.4 mm2) compared to the CG (82.32 ± 7.48 mm2) presented a p>0.05. Conclusion Glutamine supplementation associated with induced periodontal disease demonstrated a smaller amount of bone loss compared to the periodontitis group.

AbstractThe consequences of marijuana consumption during pregnancy and its effects on the function of the immune system have been little studied. Marijuana is one of the most consumed recreational drugs among pregnant women, and it is known that gestational exposure to marijuana can have serious effects on the offspring after birth. In this study, we challenged the immune system of Wistar rats by infecting them with the parasitic nematode Trichinella spiralis. A treatment group of these animals was prenatally exposed to the cannabinoid WIN 55,212-2; a control group was not exposed. At 5 days of infection, the treated animals were less effective in eliminating intestinal parasites; moreover, this effect was correlated with a deficiency in mucus production, lower recruitment of eosinophils in the duodenum, and a reduced percentage of Tγδ and NK cells. In conclusion, the gestational administration of the synthetic cannabinoid WIN 55,212-2 induces lasting changes to the function of the immune system against infection with T. spiralis in male Wistar rats, making them more susceptible to infection.

Abstract: Lysergic Acid Diethylamide (LSD) is a psychotropic drug that can be found in glue. This substance acts as serotonine and dopamine agonists and results in hallucinogenic effect. LSD is a main raw material in glue and commonly available in an affordable price. Moreover, LSD also has a direct impact on spermatozoa motility and morphology. This study aimed to obtain the change in the spermatozoa quality of wistar rats exposed to Eha-Bond glue. This was an experimental study with a completely randomized design. Saples were 10 male wistar rats (Rattus norvegicus) divided into 2 groups: control group given just food and drink; and the experimental group exposed to Eha-Bond glue 1 hour per day for 52 days. The experimental group showed a decrease in motility by 61% of B category whilst no A category found compared to the control group that had both. Morphologically, the researcher discover 68% of the abnormal morphology and 32% of the normal morphology in the experimental group. Conclusion: LSD in Eha-Bond glue influenced the decrease in spermatozoa quality -the motility and morphology- but not the concentration of spermatozoa.Keywords: LSD, psychotropic, spermatozoa qualityAbstrak: Lysergic Acid Diethylamide (LSD) merupakan salah satu narkoba jenis psikotropika yang bekerja sebagai agonis serotonin dan dopamin serta menimbulkan efek halusinasi.

<p>Liver is an organ with complex metabolism. When the liver is inflamed, cellular immunity will defend against inflammatory agents by stimulating immune cells to produce reactive oxygen species (ROS). Excessive ROS accumulation cause oxydative stress with increased  liver malondialdehyde (MDA) level. Some researches showed that purple sweet potato contain flavonoids (anthocyanins) that functioned as antioxydants. This study aimed to show the prophylactic effect of purple sweet potato extract to the liver MDA level of male Wistar rats induced by carrageenan.</p><p>This study used post-only control group method using 18 male Wistar rats divided into 3 groups: group of rats without treatment, group of rats induced by 0,1 ml of 1% carrageenan by intraplantar injection on day-8, and group of rats given with 872 mg/kgBW of purple sweet potato extract for 7 days and induced by 0,1 ml of 1% carrageenan. In the end of the study, the liver MDA levels were measured by Thio-Barbituric Acid method on each groups.</p><p>The results of One-Way ANOVA test showed there was no significant difference (p = 0,290) between group of rats without treatment (<em>x̅</em>= 207,50) and group of rats induced by carrageenan (<em>x̅</em>=233,17). Then, there is no significant difference (p = 0.978) between group of rats induced by carrageenan and group of rats given with prophylactic purple sweet potato extract and induced by carrageenan (<em>x̅</em>= 232,50).</p><p>The conclusion of this study is giving intraplantar injection of carrageenan can increase liver MDA level insignificantly and giving prophylactic purple sweet potato extract has an effect to decrease the liver MDA level of rats induced by carragenan insignificantly because it contains anthocyanins as antioxidants.</p><p> </p><strong>Keywords: </strong>Liver, <em>Ipomoea batatas</em> L., Malondialdehyde, Anthocyanins

In the study, we assessed the effect of hemp extract on activities of resistance parameters and the metabolic compound concentration in adult workers’ hemolymph. Bees were divided into the following groups: (1) control group fed with mixture of sugar and water-glycerine solution, (2) experimental group with pure sugar syrup and inside with cotton strips soaked with hemp extract, (3) experimental group with a mixture of sugar syrup with hemp extract. Hemp extracts caused an increase in the protein concentrations and reduced the protease activities regardless of the administration method. The protease inhibitor activities were decreased only in the group that received hemp extract on the strips. The biomarker activities (ALP, ALT, AST) increased from the control group and workers feeding extract in syrup and decreased in workers supplemented with the extract on strips. In young, 2-day-old workers, the glucose concentration was higher in the groups feeding with the extract than in the control. Hemp extract influenced an increase in urea concentrations in workers’ hemolymph in comparison with the control. The hemp supplementation positively influences the immune system of workers, and the appropriate method of administration may be adapted to the health problems of bees.

An intensive physical exercise program could lead to a decrease in immune system function. Effects of long-term supplementation of bovine colostrum on the response of immune function on physical exercise test in athletes were examined. Twenty-seven elite female basketball players (age 16–19) were randomly assigned to either an experimental group or a control group. Eventually, n = 11 athletes completed intervention in the experimental group (3.2 g bovine colostrum orally twice a day for 24 weeks), while n = 9 athletes in the control group were given a placebo. Before the supplementation, after 3 and 6 months, subjects performed the physical exercise stress test. Before, just after, and 3 h after physical exercise testing, blood was drawn and immune system indicators were examined. Plasma interleukin (IL)-1alpha, IL-2, IL-10, IL-13, tumor necrosis factor (TNF) alpha, creatine kinase (CK MM), immunoglobulin G (IgG), insulin-like growth factor 1 (IGF1), and WBC, lymphocyte (LYM), monocyte (MON), and granulocyte (GRA) were measured. A statistically significant change in IL-10 in response to the exercise program during the supplementation period in both groups was observed (p = 0.01). However, the results of the rest of the comparisons were statistically insignificant (p > 0.05). Contrary to our initial hypothesis, there were no significant effects of bovine supplementation on the dynamics of immune system function indicators.

The aim of this study was to investigate the clinical efficacy of vanadium complexes on triglycerides (TG), total cholesterol (Chol), uric acid (UA), urea (U), and antioxidant parameters: nonenzymatic (FRAP—ferric reducing ability of plasma, and reduced glutathione—GSH) and enzymatic (glutathione peroxidase—GPx, catalase—CAT, and GPx/CAT ratio) activity in the plasma of healthy male Wistar rats. Three vanadium complexes: [VO(bpy)2]SO4⋅2H2O, [VO(4,4′Me2bpy)2]SO4⋅2H2O, and Na[VO(O2)2(bpy)]⋅8H2O are administered by gavage during 5 weeks in two different diets such as control (C) and high fatty (F) diets. Changes of biochemical and antioxidants parameters are measured in plasma. All three vanadium complexes statistically decrease the body mass growth in comparison to the control and fatty diet. In plasma GSH was statistically increased in all vanadium complexes-treated rats from control and fatty group in comparison to only control group. Calculated GPX/CAT ratio was the highest in the control group in comparison to others.

The present investigation was carried out to evaluate the hepatoprotective effect of probiotic fermented milk (FM) containing Lactobacillus rhamnosus GG and Lactobacillus casei strain Shirota, alone as well as in combination with chlorophyllin (CHL) as an antioxidant agent in male Wistar rats administered aflatoxin-B1 (AFB1). AFB1 was injected intraperitoneally at the rate of 450 μg/kg body weight per animal twice a week for 6 weeks, maintaining an equal time interval between the two consecutive AFB1 administrations. A total of 125 male Wistar rats were randomly allocated to five groups, each group having twenty-five animals. Group I was offered FM containing L. rhamnosus GG and L. casei strain Shirota. Group II was administered AFB1 and served as the control group; group III was administered FM-AFB1, in which besides administering AFB1, FM was also offered. Group IV was offered CHL and AFB1, and group V was offered both FM and CHL along with AFB1. The rats were euthanised at the 15th and 25th week of the experiment and examined for the biochemical and hepatopathological profile. A significant reduction in thiobarbituric acid-reactive substances (TBARS) was observed in the FM–CHL–AFB1 group compared with the AFB1 control group. FM alone or in combination with CHL was found to show a significant (P < 0·05) hepatoprotective effect by lowering the levels of TBARS and by enhancing the activities of antioxidant enzymes such as glutathione peroxidase, superoxide dismutase, catalase and glutathione-S-transferase, indicating that probiotic FM alone or in combination with CHL possesses a potent protective effect against AFB1-induced hepatic damage.
