Synergy1, a prebiotic composed of Inulin and Oligofructose (1 : 1). Soybean meal is a natural source of isoflavones. The objective was to investigate the effects of feeding Synergy1 and SM on the incidence of azoxymethane- (AOM-) induced aberrant crypt foci (ACF) in Fisher 344 male rats. Rats (54) were randomly assigned to 9 groups (n=6). Control group (C) was fed AIN-93G and treatment groups Syn1 and SM at 5% and 10% singly and in combinations. Rats were injected with two s/c injections of AOM at 7 and 8 weeks of age at 16 mg/kg body weight and killed at 17 weeks by CO2asphyxiation. Colonic ACF enumeration and hepatic enzyme activities were measured. Reductions (%) in total ACF among treatment groups fed combinations were higher (67–77) compared to groups fed singly (52–64). Synergistic mechanisms among phytochemicals may be responsible suggesting protective role in colon carcinogenesis with implications in food product development.

Prebiotic fructans are nondigestible carbohydrates with numerous health benefits. Soybean is a rich source of phytonutrients such as isoflavones. The objective of this study was to evaluate the chemopreventive effects of prebiotics (Synergy1) and soybean meal (SM) at 5% and 10% levels alone and in combination on azoxymethane- (AOM-) induced colon carcinogenesis. After one wk of acclimatization, Fisher 344 male rats (N=90) were randomly assigned to 9 groups (n=10). Control rats (C) were fed AIN-93G/M. Two s/c injections of AOM were administered to rats at 7 and 8 wk of age at 16 mg/kg body weight. Rats were killed by CO2asphyxiation at 45 wk. Tumor incidence (%) in treatment groups ranged from 40 to 75 compared to 100 in C. Results indicate that feeding prebiotics and soybean in combination significantly reduced incidence of AOM-induced colon tumors with implications for food industry in the food-product development.

In the present study, 30 male rats (age 3 mos, Wt 128.6 ± 3.7 g) were randomly divided into Control group (CG), Experimental group (EG), and Supplemented group (SG), 10 per group. An exercise protocol (3 hrs swimming per day, 5 days a week for 4 weeks) was followed in EG and SG, with no exercise in CG. In SG, α-tocopherol succinate was injected subcutaneouly at a dose of 50 mg•kg−1 per body weight per day. After 4 weeks of exercise, significant diminutions (p <  0.05) were noted in somatic indices of testes and accessory sex organs; seminiferous tubuler diameter (STD); testicular Δ5, 3β-hydroxysteroid dehydrogenase (Δ5, 3β-HSD) 17 β-hydroxysteroid dehydrogenase (17 β-HSD) activities; plasma levels of testosterone (T), luteinizing hormone (LH); preleptotine spermatocytes (pLSc), mid-pachytene spermatocytes (mPSc), and Stage 7 spermatids (7 Sd); testicular α-tocopherol and glutathione (GSH) content; superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), and glutathione-s-transferase (GST) activities in EG when compared to CG. Moreover, a significant elevation (p <  0.05) in malondialdehyde (MDA) was found in testes of EG compared to CG. No significant alteration was noted in body weight among the groups. Co-administration of α-tocopherol succinate restored the above parameters. Intensive swimming exercise-induced oxidative stress causes dysfunction in the male reproductive system, which can be protected by α-tocopherol succinate.

Phytochemical composition and antioxidant activity of flowers decoction at post-flowering stage (F3D) of Opuntia dejecta were determined. The obtained findings demonstrate that F3D has a marked antioxidant activity in all tested assays. Furthermore, the present study was designed to test the protective activity of F3D against induced Diabetes type 2 (DT2) in male rats. Those metabolic syndromes were induced by a high-fructose diet (HFD) (10% fructose solution) for a period of 20 weeks. F3D was administered orally (100 and 300 mg/kg body weight) daily for the last 4 weeks. Metformin (150 mg/kg body weight) was used as a standard drug and administrated orally for the last 4 weeks. The results showed a significant increase in blood glucose, triglycerides and hepatic markers (ALAT, ASAT and ALK-P) in HFD group. A significant increase in hepatic TBARS and a significant decrease in SOD, CAT and GPX were observed in fructose fed rats compared to control group. Administration of F3D showed a protective effect in biochemical and oxidative stress parameters measured in this study. Also, oral administration of F3D restored the histological architecture of rat liver in comparison with rats fed HFD. In conclusion, F3D attenuated hepatic oxidative stress in fructose-fed rats.

This study examined the effects of increasing levels of dietary fat fed isocalorically on body weight, body composition, and adipose distribution. Adult male rats were weight matched into four groups. One group that was fed a low-fat diet (12%) served as reference controls. The other three groups were fed diets of 24, 36, or 48% fat in amounts to equal the energy intake of the control group. After 6 wk, body weights of the four groups were not significantly different. Intrascapular brown fat did not differ between groups. Total body fat and adipose depot weights, however, increased in proportion to the level of fat in the diet. Total body fat and retroperitoneal and mesenteric depot weights of the 48% fat group were greater than controls (P < 0.05). Mesenteric fat in this group was also significantly increased over all other groups (P < 0.05). These results show that high-fat diets fed to adult animals cause increased body fat in the absence of significant changes in body weight and that mesenteric fat is increased disproportionately.

Background: Among venomous elapid snakes, cobras have the highest public awareness, as their venom represents a combination of proteins, peptides, and enzymes that have a range of biochemical and pharmacological roles and are also the main constitutes of biological activity and lethal toxicity. Objectives: The study aimed to evaluate the effect of the venom of Egyptian Spitting Cobra, Naja nubiae, on the vascular permeability based on the extravasation of the azo dye Evans blue (EB) into the tissues of the liver and kidneys of animals envenomed with low (¼ LD50; 0.32 mg/kg) and high (½ LD50; 0.65 mg/ kg) doses at three sampling times (30, 120, 360 min) post-injection of the venom. Methods: Fifty-four adult male Albino rats (8 weeks old and 180±2 0 g body weight) were divided into three main groups (n=6). In the control group, rats were subcutaneously (SC) injected with saline solution. Envenomed groups were SC injected, one group with 0.32 mg/kg and the other group with 0.65 mg/kg body weight of crude venom, respectively. Rats were I.V injected with EB dye 20 minutes before SC injection with saline solution as control animals and with Naja nubiae venom as treatment groups. Results: The results illustrated a high significant rate of EB extravasation to hepatic and renal tissues by the colorimetric determination of EB dye concentration. Conclusion: The venom of Naja nubiae can cause increased hepatic and renal vascular permeability which may explain the inflammatory effect induced by this venom.

Aging is an oxidative stress-associated process that progresses with age. Our aim is to delay or attenuate these oxidative alterations and to keep individuals healthy as they age using natural compounds supplementation. Therefore, we conducted the present study to investigate the protective potentials of quercetin against D-galactose (D-gal)-associated oxidative alterations that were induced experimentally in male Wistar rats. Forty-five rats were randomly allocated into five groups of nine rats each. The groups were a control group that was reared on a basal diet and injected subcutaneously with 120 mg D-gal dissolved in physiological saline solution (0.9% NaCl) per kg body weight daily and quercetin-treated groups that received the same basal diet and subcutaneous daily D-gal injections were supplemented orally with 25, 50, and 100 mg of quercetin per kg body weight for 42 days. Pancreatic and renal samples were subjected to histopathological, immunohistochemical, and relative mRNA expression assessments. Aging (p53, p21, IL-6, and IL-8), apoptotic (Bax, CASP-3, and caspase-3 protein), proliferative (Ki67 protein), antiapoptotic (Bcl2 and Bcl2 protein), inflammatory (NF-κB, IL-1β, and TNF-α), antioxidant (SOD1), and functional markers (GCLC and GCLM genes and insulin, glucagon, and podocin proteins) were determined to evaluate the oxidative alterations induced by D-gal and the protective role of quercetin. D-gal caused oxidative alterations of the pancreas and kidneys observed via upregulations of aging, apoptotic, and inflammatory markers and downregulated the antiapoptotic, proliferative, antioxidant, and functional markers. Quercetin potentially attenuated these aging-related oxidative alterations in a dose-dependent manner. Finally, we can conclude that quercetin supplementation is considered as a promising natural protective compound that could be used to delay the aging process and to maintain human health.

BuPiHeWei (BPHW) decoction, a classic Traditional Chinese Medicinal (TCM) prescription, has been widely used in clinical practice to relieve digestive symptoms caused by chemotherapy, such as diarrhea and vomiting. The present study aimed to investigate whether BPHW decoction exerted a protective role in the 5-Fu-induced intestinal mucosal injury in the rats by regulating the mechanisms of TLR-4/NF-κB signaling pathway. There were 35 Sprague Dawley rats randomly divided into four groups: normal control group, 5-Fu group, 5-Fu + BPHW decoction group (10.5 g/kg, for five continuous days), and 5-Fu + Bacillus licheniformis capsule group (0.2 g/kg, for five continuous days). Animal models were established by intraperitoneal injection of 5-Fu (30 mg/Kg, for five consecutive days). At the end of the treatment period, body weight, diarrhea score, and histological examination were examined. Furthermore, the expression of TLR-4/NF-κB pathway was detected to reveal its mechanism. The results showed that BPHW decoction effectively reduced diarrhea score and increased body weight and height of villi after 5-Fu chemotherapy. In addition, BPHW decoction could significantly inhibit the expression of TLR-4, NF-κB, and inflammatory factors (including TNF-α, IL-1β, and IL-6) in the intestine, and the efficacy was significantly higher than that of Bacillus licheniformis capsule. In summary, BPHW decoction might be considered an effective drug to alleviate intestinal mucosal injury in the rats induced by 5-Fu.

 Objective: The current study was designed to estimate the potential protective role of the aqueous extract of rosemary (AER) (Rosmarinus officinalis) against trichloroacetic acid (TCA)-created hepatotoxicity in male albino rats.Methods: Forty male albino rats were separated into four groups of ten: Group I served as control; Group II was given AER (200 mg/kg/day) by gavage; Group III received TCA at the dose 50 mg/kg/day, and Group V was treated with AER (200 mg/kg/day) and received TCA (50 mg/kg/day). The experiment was carried out for 2 months.Results: The toxicity of TCA for rats was revealed by an elevation in liver marker enzymes activities (gamma-glutamyl transferase [GGT], alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and conjugated bilirubin (CB) level, and a decrease in albumin and total protein (TP) levels. The TCA administration also caused a significant increase in the activities of catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and also malondialdehyde (MDA) level in liver tissues. These biochemical effects were accompanied by histological indicators of liver damage. Treatment with ARE recovered the liver damage instigated by TCA, as showed by perfection of liver enzyme markers (GGT, ALT, AST, ALP), CB, TP and albumin; as well as antioxidant parameters (CAT, SOD, GPx) and lipid peroxidation (MDA) and amelioration of histopathology changes in the liver tissues.Conclusion: It could be concluded that AER supplementation for 2 months in TCA-induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.
