Anti-Inflammatory and Antioxidant Effects Induced by Allium sativum L. Extracts on an Ex Vivo Experimental Model of Ulcerative Colitis. Foods 2022; 11:foods11223559. [PMID: 36429152 PMCID: PMC9689397 DOI: 10.3390/foods11223559] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 10/25/2022] [Accepted: 11/04/2022] [Indexed: 11/11/2022] Open
Abstract
Inflammatory bowel diseases (IBDs) are chronic and multifactorial inflammatory conditions of the colonic mucosa (ulcerative colitis), characterized by increased and unbalanced immune response to external stimuli. Garlic and its bioactive constituents were reported to exert various biological effects, including anti-inflammatory, antioxidant and immunomodulatory activities. We aimed to evaluate the protective effects of a hydroalcoholic (GHE) and a water (GWE) extract from a Sicilian variety of garlic, known as Nubia red garlic, on an ex vivo experimental model of ulcerative colitis, involving isolated LPS-treated mouse colon specimens. Both extracts were able to counteract LPS-induced cyclooxygenase (COX)-2, tumor necrosis factor (TNF)-α, nuclear factor-kB (NF-kB), and interleukin (IL)-6 gene expression in mouse colon. Moreover, the same extracts inhibited prostaglandin (PG)E2, 8-iso-PGF2α, and increased the 5-hydroxyindoleacetic acid/serotonin ratio following treatment with LPS. In particular, GHE showed a better anti-inflammatory profile. The anti-inflammatory and antioxidant effects induced by both extracts could be related, at least partially, to their polyphenolic composition, with particular regards to catechin. Concluding, our results showed that GHE and GWE exhibited protective effects in colon, thus suggesting their potential use in the prevention and management of ulcerative colitis.

Administration of Lactobacillus reuteri Combined with Clostridium butyricum Attenuates Cisplatin-Induced Renal Damage by Gut Microbiota Reconstitution, Increasing Butyric Acid Production, and Suppressing Renal Inflammation. Nutrients 2021; 13:nu13082792. [PMID: 34444952 PMCID: PMC8402234 DOI: 10.3390/nu13082792] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 07/28/2021] [Accepted: 08/09/2021] [Indexed: 01/02/2023] Open
Abstract
Cisplatin-induced nephrotoxicity is associated with gut microbiota disturbance. The present study aimed to investigate whether supplementation of Lactobacillus reuteri and Clostridium butyricum (LCs) had a protective effect on cisplatin-induced nephrotoxicity through reconstruction of gut microbiota. Wistar rats were given different treatments: control, cisplatin (Cis), cisplatin + C. butyricum and L. reuteri (Cis+LCs), and C. butyricum and L. reuteri (LCs). We observed that cisplatin-treated rats supplemented with LCs exhibited significantly decreased renal inflammation (KIM-1, F4/80, and MPO), oxidative stress, fibrosis (collagen IV, fibronectin, and a-SMA), apoptosis, concentration of blood endotoxin and indoxyl sulfate, and increased fecal butyric acid production compared with those without supplementation. In addition, LCs improved the cisplatin-induced microbiome dysbiosis by maintaining a healthy gut microbiota structure and diversity; depleting Escherichia-Shigella and the Enterobacteriaceae family; and enriching probiotic Bifidobacterium, Ruminococcaceae, Ruminiclostridium_9, and Oscillibacter. Moreover, the LCs intervention alleviated the cisplatin-induced intestinal epithelial barrier impairment. This study indicated LCs probiotic serves as a mediator of the gut–kidney axis in cisplatin-induced nephrotoxicity to restore the intestinal microbiota composition, thereby suppressing uremic toxin production and enhancing butyrate production. Furthermore, the renoprotective effect of LCs is partially mediated by increasing the anti-inflammatory effects and maintaining the integrity of the intestinal barrier.

Abstract
Purpose: To evaluate the effect of garlic on formation of postoperative adhesions in
rats. Methods: Twenty-four Sprague dawley rats were divided into three groups. In Group 1
(sham), laparotomy was performed and stitched up. In Group 2 (control),
after laparotomy was performed, punctate hemorrhage was induced by cecal
abrasion in the cecum and 2 cc of saline was intraperitoneally administered
to each rat. In Group 3 (experimental), after laparotomy was performed,
punctate hemorrhage was induced by cecal abrasion in the cecum and each rat
was intraperitoneally administered a sterile Allium sativum derivative. The
rats in all groups were re-laparotomized on postoperative day 7; samples
were obtained from the peritoneal tissue surrounding the cecum Results: In Group 3, there was a statistically significant difference in terms of
inflammation, lymph node size, and free oxygen radicals; these parameters
tended to increase. In terms of fibrosis evaluated using H&E and MT,
there was no significant difference between groups 2 and 3. Conclusions: No positive outcomes indicating that Allium sativum reduces intra-abdominal
adhesions were obtained. However, it caused severe inflammation in the
tissue. Additionally, in immunohistochemical analyses conducted to detect
oxidative stress, allium sativum increased the production of free oxygen
radicals in the tissue.

Abstract
Organosulfur compounds are bioactive components of garlic essential oil (EO), mustard oil, Ferula EOs, asafoetida, and other plant and food extracts. Traditionally, garlic (Allium sativum) is used to boost the immune system; however, the mechanisms involved in the putative immunomodulatory effects of garlic are unknown. We investigated the effects of garlic EO and 22 organosulfur compounds on human neutrophil responses. Garlic EO, allyl propyl disulfide, dipropyl disulfide, diallyl disulfide, and allyl isothiocyanate (AITC) directly activated Ca2+ flux in neutrophils, with the most potent being AITC. Although 1,3-dithiane did not activate neutrophil Ca2+ flux, this minor constituent of garlic EO stimulated neutrophil reactive oxygen species (ROS) production. In contrast, a close analog (1,4-dithiane) was unable to activate neutrophil ROS production. Although 1,3-dithiane-1-oxide also stimulated neutrophil ROS production, only traces of this oxidation product were generated after a 5 h treatment of HL60 cells with 1,3-dithiane. Evaluation of several phosphatidylinositol-3 kinase (PI3K) inhibitors with different subtype specificities (A-66, TGX 221, AS605240, and PI 3065) showed that the PI3K p110δ inhibitor PI 3065 was the most potent inhibitor of 1,3-dithiane-induced neutrophil ROS production. Furthermore, 1,3-dithiane enhanced the phosphorylation of extracellular signal-regulated kinase 1/2 (ERK1/2), glycogen synthase kinase 3 α/β (GSK-3α/β), and cAMP response element binding (CREB) protein in differentiated neutrophil-like HL60 cells. Density functional theory (DFT) calculations confirmed the reactivity of 1,3-dithiane vs. 1,4-dithiane, based on the frontier molecular orbital analysis. Our results demonstrate that certain organosulfur compounds can activate neutrophil functional activity and may serve as biological response modifiers by augmenting phagocyte functions.

Preventive Effect of Garlic Oil and Its Organosulfur Component Diallyl-Disulfide on Cigarette Smoke-Induced Airway Inflammation in Mice. Nutrients 2018; 10:nu10111659. [PMID: 30400352 PMCID: PMC6267300 DOI: 10.3390/nu10111659] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Revised: 10/31/2018] [Accepted: 11/01/2018] [Indexed: 12/28/2022] Open
Abstract
Garlic (Allium sativum) has traditionally been used as a medicinal food and exhibits various beneficial activities, such as antitumor, antimicrobial, hypolipidemic, antiarthritic, and hypoglycemic activities. The aim of this study was to explore the preventive effect of garlic oil (GO) and its organosulfur component diallyl disulfide (DADS) on cigarette smoke (CS)-induced airway inflammation. Mice were exposed to CS daily for 1 h (equivalent to eight cigarettes per day) for two weeks, and intranasally instilled with lipopolysaccharide (LPS) on day 12 after the initiation of CS exposure. GO and DADS were administered to mice by oral gavage, both at rates of 20 and 40 mg/kg, for 1 h before CS exposure for two weeks. In the bronchoalveolar lavage fluid, GO and DADS inhibited the elevation in the counts of inflammatory cells, particularly neutrophils, which were induced in the CS and LPS (CS + LPS) group. This was accompanied by the lowered production (relative to the CS + LPS group) of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α. Histologically, GO and DADS inhibited the CS- and LPS-induced infiltration of inflammatory cells into lung tissues. Additionally, GO and DADS inhibited the phosphorylation of extracellular signal-regulated kinase and the expression of matrix metalloproteinase-9 in the lung tissues. Taken together, these findings indicate that GO and DADS could be a potential preventive agent in CS-induced airway inflammation.

Abstract
Plants produce an extensive array of organic compounds derived from secondary metabolism that may be useful in animal nutrition because of their chemical makeup. These plant-derived bioactive compounds, also referred to as phytonutrients (PN) or phytobiotics, have been shown to express antimicrobial activities against a wide range of bacteria, yeast, and fungi and have been investigated as rumen modifiers in ruminant nutrition. Studies have reported that PN may inhibit deamination of AA and methanogenesis in the rumen and shift fermentation toward propionate and butyrate. Most of the experiments, however, have been conducted in vitro, and responses have been highly variable and inconsistent in animal experiments. In addition, some studies have reported that PN had positive effects on productivity, although rumen fermentation was not affected. Other than antimicrobial effects in the gut, PN are known to bind specific receptors expressed in neurons, intestines, and other cells and exhibit related physiological effects in nonruminants. The receptor-mediated effects include immune responses, oxidative stress, and insulin secretion and activity. Some PN, due to their phenolic nature, are likely less susceptible to microbial degradation in the rumen and may exhibit activities postruminally, similar to their mode of action in nonruminant species. This opens a new area of research in ruminants, including effects of PN on the animal's immune system, postruminal nutrient use, and animal physiology. Although limited, studies with ruminants provide first evidence of PN's regulatory effects on the host responses. For example, PN were reported to regulate immune cells related to adaptive and innate immunity in challenged or nonchallenged dairy cows. Supplementation of PN reduced oxidative stress by decreasing lipid peroxidation and increasing endogenous antioxidants in ruminants. Additionally, insulin secretion and sensitivity were reportedly regulated by PN in dairy cows. The regulatory effects of PN on immunity may be beneficial for immune suppression and inflammation in dairy cows. In addition, PN could positively affect energy partitioning for milk production through their effects on insulin secretion and sensitivity. Further research is needed to elucidate the effect and mode of action of PN on immune function and animal energetics.

Medicinal plants--prophylactic and therapeutic options for gastrointestinal and respiratory diseases in calves and piglets? A systematic review. BMC Vet Res 2016; 12:89. [PMID: 27268043 PMCID: PMC4896019 DOI: 10.1186/s12917-016-0714-8] [Citation(s) in RCA: 59] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2015] [Accepted: 05/30/2016] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Gastrointestinal and respiratory diseases in calves and piglets lead to significant economic losses in livestock husbandry. A high morbidity has been reported for diarrhea (calves ≤ 35%; piglets ≤ 50%) and for respiratory diseases (calves ≤ 80%; piglets ≤ 40%). Despite a highly diverse etiology and pathophysiology of these diseases, treatment with antimicrobials is often the first-line therapy. Multi-antimicrobial resistance in pathogens results in international accordance to strengthen the research in novel treatment options. Medicinal plants bear a potential as alternative or additional treatment. Based on the versatile effects of their plant specific multi-component-compositions, medicinal plants can potentially act as 'multi-target drugs'. Regarding the plurality of medicinal plants, the aim of this systematic review was to identify potential medicinal plant species for prevention and treatment of gastrointestinal and respiratory diseases and for modulation of the immune system and inflammation in calves and piglets. RESULTS Based on nine initial sources including standard textbooks and European ethnoveterinary studies, a total of 223 medicinal plant species related to the treatment of gastrointestinal and respiratory diseases was identified. A defined search strategy was established using the PRISMA statement to evaluate 30 medicinal plant species starting from 20'000 peer-reviewed articles published in the last 20 years (1994-2014). This strategy led to 418 references (257 in vitro, 84 in vivo and 77 clinical trials, thereof 48 clinical trials in veterinary medicine) to evaluate effects of medicinal plants and their efficacy in detail. The findings indicate that the most promising candidates for gastrointestinal diseases are Allium sativum L., Mentha x piperita L. and Salvia officinalis L.; for diseases of the respiratory tract Echinacea purpurea (L.) MOENCH, Thymus vulgaris L. and Althea officinalis L. were found most promising, and Echinacea purpurea (L.) MOENCH, Camellia sinensis (L.) KUNTZE, Glycyrrhiza glabra L. and Origanum vulgare L. were identified as best candidates for modulation of the immune system and inflammation. CONCLUSIONS Several medicinal plants bear a potential for novel treatment strategies for young livestock. There is a need for further research focused on gastrointestinal and respiratory diseases in calves and piglets, and the findings of this review provide a basis on plant selection for future studies.

Abstract
AIMS Garlic oil (GO) is used for centuries in folk medicine as a therapy for many diseases including inflammatory disorders. Recently, it has exhibited potent anti-oxidant, anti-inflammatory and immunomodulatory effects. Consequently, we evaluated the possible protective effect of GO in a rat model of colitis, induced by dextran sulfate sodium (DSS). MAIN METHODS Colitis induced by allowing rats a free access to drinking water containing 5% DSS for 7 days, from day 1 to day 7. GO was administered orally in doses of 25, 50 and 100mg/kg/day. Mesalazine used as a standard medication in a dose of 15 mg/kg/day. All animals fasted for 2h, 1h before and 1h after giving the treatment, which introduced daily for 7 days, from day 1 to day 7, at 10:00 to 11:00 A.M. Animal body, and colonic weights, colonic myeloperoxidase (MPO), and superoxide dismutase (SOD) activities, colonic reduced-glutathione (GSH), malondialdehyde (MDA), tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-10 levels, macroscopic and microscopic changes of colonic tissues were evaluated. KEY FINDINGS GO treatment significantly suppressed the elevated colonic weight, MPO activity, MDA, TNF-α and IL-1β levels. However, it potentiated the decrease body weight, colonic SOD activity, GSH and IL-10 levels. Moreover, it ameliorated the marked macroscopic and microscopic changes of colonic mucosa in a dose dependent manner. SIGNIFICANCE Garlic oil inhibits DSS-induced colitis in rats may be through its anti-oxidant, anti-inflammatory and immunomodulatory properties. Therefore, GO could be a promising protective agent recommended for UC patients.

Abstract
Endotoxin is a potent microbial mediator implicated in sepsis. We investigated the anti-inflammatory effect of leaf essential oil from Cinnamomum osmophloeum Kanehira (CO) of the linalool chemotype on endotoxin-injected mice. Mice were administered CO or vehicle by gavage before endotoxin injection and were killed 12 h after injection. Neither growth nor the organ weight or tissue weight to body weight ratio was affected by CO treatment. CO significantly lowered peripheral levels of tumor necrosis factor-α, interleukin (IL)-1β, IL-18, interferon-γ, and nitric oxide and inhibited the expression of toll-like receptor 4 (TLR4), myeloid differentiation primary response gene (88), myeloid differentiation factor 2, apoptosis-associated speck-like protein containing a caspase-recruitment domain (ASC), caspase-1, and Nod-like receptor family, pyrin domain containing 3 (NLRP3). CO also inhibited the activation of nuclear factor-ĸB, inhibited the activity of caspase-1 in small intestine, and ameliorated intestinal edema. Our data provide strong evidence for a protective effect of CO of the linalool chemotype in the endotoxin-induced systemic inflammatory response in close association with suppression of the TLR4 and NLRP3 signaling pathways in intestine.

Abstract
SCOPE Inflammatory bowel disease (IBD) is an incurable disease which affects millions of people. Garlic (Allium sativum) preparations have been traditionally employed for the treatment of diseases affecting the digestive tract. Here, we have investigated the effect of diallyl sulfide (DAS) and diallyl disulfide (DADS), two garlic-derived sulfur compounds, on intestinal inflammation in vivo as well as in intestinal isolated cells. METHODS AND RESULTS Colitis was induced in mice by intracolonic administration of dinitrobenzenesulfonic acid. Intestinal damage was assessed by evaluating colon weight/colon length ratio and by histology. Murine intestinal epithelial cells stimulated with IFN-γ were used to evaluate the possible in vitro DAS and DADS anti-inflammatory effects. DAS and DADS, given for two consecutive days after DNBS administration, reduced inflammation and damage. In IFN-γ-stimulated intestinal epithelial cells, DADS reduced IP-10 and IL-6 levels, while DAS inhibited nitric oxide production and STAT-1 expression. CONCLUSION DAS and DADS exert therapeutic effects in the DNBS model of colitis. The actions of these compounds on the production of IP-10, IL-6, hydrogen sulfide or nitric oxide and on the expression of STAT-1 observed in intestinal cells stimulated with IFN-γ, might explain the protective action of DAS and DADS in experimental IBD.

Abstract
OBJECTIVE(S) Peritoneal adhesion is a serious problem that develops after most abdominopelvic surgeries. Allium sativum (garlic) has been used for centuries as both a nutrient and a traditional medicine. The anti-inflammatory, antibacterial, fibrinolytic, and wound-healing properties of garlic are well-recognized. We evaluated the effect of garlic on formation of postoperative adhesions in rats. STUDY DESIGN Thirty Wistar-Albino female rats weighing 200-250 g were randomly divided into three groups (10 rats/group). Group 1 rats received 5 ml/kg garlic oil intraperitoneally and no surgery was performed. The ceca of Group 2 rats (controls) were scraped, to trigger adhesion formation, and no treatment was given. In Group 3 rats, 5 ml/kg garlic oil was added to the peritoneal cavity immediately after the cecum was scraped. All animals were sacrificed 10 d after surgery and adhesions graded in terms of severity and histopathologic characteristics. RESULTS All animals tolerated the operations well. No adhesions were evident upon laparotomy of Group 1 animals. In Group 2 three rats had an adhesion grade 2 and seven rats had an adhesion of grade 3, whereas in Group 3 no adhesions were found in four rats, five rats had an adhesion grade of 1. Only one rat had a grade 2 adhesion. Macroscopic adhesions and mean adhesion scores of Group 3 were significantly lower than Group 2 (p<0.001). Histopathologic evaluation of the specimens also revealed a statistically significant differences in inflammation, fibrosis, and neovascularization scores between Group 2 and 3 (p=0.001, p=0.001, and p=0.011, respectively). Inflammation, fibrosis and vascularization scores in Group 3 were found significantly lower than Group 2. CONCLUSION The anti-inflammatory, antibacterial, fibrinolytic, antithrombotic, and wound-healing effects of garlic likely prevent formation of peritoneal adhesions in a rat model, and garlic may be effective and cheap when used to prevent such adhesions in humans.

Immune and production responses of dairy cows to postruminal supplementation with phytonutrients. J Dairy Sci 2013; 96:7830-43. [PMID: 24140326 DOI: 10.3168/jds.2013-7089] [Citation(s) in RCA: 50] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2013] [Accepted: 08/31/2013] [Indexed: 01/08/2023]
Abstract
This study investigated the effect of phytonutrients (PN) supplied postruminally on nutrient utilization, gut microbial ecology, immune response, and productivity of lactating dairy cows. Eight ruminally cannulated Holstein cows were used in a replicated 4×4 Latin square. Experimental periods lasted 23 d, including 14-d washout and 9-d treatment periods. Treatments were control (no PN) and daily doses of 2g/cow of either curcuma oleoresin (curcumin), garlic extract (garlic), or capsicum oleoresin (capsicum). Phytonutrients were pulse-dosed into the abomasum of the cows, through the rumen cannula, 2 h after feeding during the last 9 d of each experimental period. Dry matter intake was not affected by PN, although it tended to be lower for the garlic treatment compared with the control. Milk yield was decreased (2.2 kg/d) by capsicum treatment compared with the control. Feed efficiency, milk composition, milk fat and protein yields, milk N efficiency, and 4.0% fat-corrected milk yield were not affected by treatment. Rumen fermentation variables, apparent total-tract digestibility of nutrients, N excretion with feces and urine, and diversity of fecal bacteria were also not affected by treatment. Phytonutrients had no effect on blood chemistry, but the relative proportion of lymphocytes was increased by the capsicum treatment compared with the control. All PN increased the proportion of total CD4(+) cells and total CD4(+) cells that co-expressed the activation status signal and CD25 in blood. The percentage of peripheral blood mononuclear cells (PBMC) that proliferated in response to concanavalin A and viability of PBMC were not affected by treatment. Cytokine production by PBMC was not different between control and PN. Expression of mRNA in liver for key enzymes in gluconeogenesis, fatty acid oxidation, and response to reactive oxygen species were not affected by treatment. No difference was observed due to treatment in the oxygen radical absorbance capacity of blood plasma but, compared with the control, garlic treatment increased 8-isoprostane levels. Overall, the PN used in this study had subtle or no effects on blood cells and blood chemistry, nutrient digestibility, and fecal bacterial diversity, but appeared to have an immune-stimulatory effect by activating and inducing the expansion of CD4 cells in dairy cows. Capsicum treatment decreased milk yield, but this and other effects observed in this study should be interpreted with caution because of the short duration of treatment.

Abstract
The aim of the present study was to investigate whether oxidative stress and immune dysfunction could be attenuated by Ganoderma atrum polysaccharide (PSG-1) in d-galactose (d-gal)-induced aging mice, and provide evidence for its effects. The results showed that PSG-1 significantly decreased lipid peroxidation in liver, brain, and spleen, but concomitantly increased the activities of superoxide dismutase, catalase, and glutathione peroxidase compared with the d-gal group. Elevation of glutathione contents and attenuation of glutathione disulfide contents were also found in PSG-1-treated animals. Furthermore, the results showed that PSG-1 treatment increased basal lymphocyte proliferation as well as T cell and B cell proliferation and enhanced interleukin-2 production. Taken together, the results suggested that PSG-1 had potential as a novel agent to promote health and improve aging-associated pathologies, at least in part, via modification of the redox system and improvement of immune function.
