Abstract
Compared to injection administration, oral administration is free of discomfort, wound infection, and complications and has a higher compliance rate for patients with diverse diseases. However, oral administration reduces the bioavailability of medicines, especially biologics (e.g., peptides, proteins, and antibodies), due to harsh gastrointestinal biological barriers. In this context, the development and prosperity of nanotechnology have helped improve the bioactivity and oral availability of oral medicines. On this basis, first, the biological barriers to oral administration are discussed, and then oral nanomedicine based on organic and inorganic nanomaterials and their biomedical applications in diverse diseases are reviewed. Finally, the challenges and potential opportunities in the future development of oral nanomedicine, which may provide a vital reference for the eventual clinical transformation and standardized production of oral nanomedicine, are put forward.

Chronic consumption of sweeteners in mice and its effect on the immune system and the small intestine microbiota. ACTA ACUST UNITED AC 2021; 41:504-530. [PMID: 34559497 PMCID: PMC8519602 DOI: 10.7705/biomedica.5806] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Indexed: 02/08/2023]
Abstract
Introduction: Sweeteners are additives used in different foods. They can be natural (sucrose and stevia) or artificial (sucralose). Currently, they are routinely consumed in multiple products and their effects on the mucosa of the small intestine and its microbiota are still controversial.
Objective: To relate the consumption of sweeteners and their effect on the immune system and the microbiota of the small intestine in CD1 mice.
Materials and methods: We used 54 three-week-old CD1 mice divided into three groups in the experiments: 1) A group of three weeks without treatment, 2) a group treated for six weeks, and 3) a group treated for 12 weeks using sucrose, sucralose, and stevia. We obtained CD19+ B lymphocytes, IgA+ antibodies, transforming growth factor-beta (TGF-b), and interleukins 12 and 17 (IL-12 and -17) from Peyer’s patches and lamina propria cells while DNA was obtained from intestinal solids to identify bacterial species.
Results: After 12 weeks, sucrose and sucralose consumption caused a reduction in bacterial communities with an increase in CD19+, a decrease in IgA+ and TGF-b, and an increase in IL-12 and -17 in the Peyer’s patches while in the lamina propria there was an increase in all parameters. In contrast, stevia led to an improvement in bacterial diversity and percentage of CD19+ lymphocytes with minimal increase in IgA+, TGF-b, and IL-12, and a decrease in IL-17.
Conclusion: Sucrose and sucralose caused negative alterations in bacterial diversity and immune parameters after 12 weeks; in contrast, stevia was beneficial for the intestinal mucosa.

Abstract
The call for a paradigm change in toxicology from the United States National Research Council in 2007 initiates awareness for the invention and use of human-relevant alternative methods for toxicological hazard assessment. Simple 2D in vitro systems may serve as first screening tools, however, recent developments infer the need for more complex, multicellular organotypic models, which are superior in mimicking the complexity of human organs. In this review article most critical organs for toxicity assessment, i.e., skin, brain, thyroid system, lung, heart, liver, kidney, and intestine are discussed with regards to their functions in health and disease. Embracing the manifold modes-of-action how xenobiotic compounds can interfere with physiological organ functions and cause toxicity, the need for translation of such multifaceted organ features into the dish seems obvious. Currently used in vitro methods for toxicological applications and ongoing developments not yet arrived in toxicity testing are discussed, especially highlighting the potential of models based on embryonic stem cells and induced pluripotent stem cells of human origin. Finally, the application of innovative technologies like organs-on-a-chip and genome editing point toward a toxicological paradigm change moves into action.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2020; 196:110548. [PMID: 32278140 DOI: 10.1016/j.ecoenv.2020.110548] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 03/23/2020] [Accepted: 03/25/2020] [Indexed: 06/11/2023]
Abstract
As kinds of endocrine disruptors, organophosphate esters (OPEs) pollution in the environment had received increasing attention recently. Food and water intake were two important exposure pathways for OPEs. However, the studies about the potential association between OPEs and gastrointestinal cancer were limited. This study investigated the possible association between OPEs and gastrointestinal cancer. All cancer patients were diagnosed with gastrointestinal cancer from a Grade 3 A hospital in Wuhan, China, while the control group was non-cancer healthy persons. The results showed that 6 OPEs were found in the control samples, while 8 in the samples from patients with gastrointestinal cancer. The detection frequencies of OPEs in gastrointestinal cancer patients were significantly higher than those in the control group (p < 0.05 or p < 0.01), except for triethyl phosphate (TEP) and tris (methylphenyl) phosphate (TMPP) in the gastric cancer group. The concentrations of OPEs in the control group were significantly lower than those in the gastric cancer group and colorectal cancer group (p < 0.01). In the control group and gastrointestinal cancer group, TEP was the dominant pollutant. Correlation analysis found that concentrations of TEP, tris(2-chloroisopropyl) phosphate (TCIPP), triphenyl phosphate (TPHP), TMPP, tris(2-ethylhexyl) phosphate (TEHP), and 2-ethylhexyl diphenyl phosphate (EHDPP) were associated with gastric cancer (p < 0.01), and concentrations of TEP, TCIPP, TPHP, TMPP and TEHP were associated with colorectal cancer (p < 0.01). A cluster analysis divided the 34 patients with gastric cancer and 40 patients with colorectal cancer in four groups. The results showed that the elderly male patients with gastric cancer were more sensitive to the exposure of EHDPP, while the TEP exposure was more sensitive to the relatively young gastrointestinal cancer patients. These findings indicated that OPEs might play a role in developing gastrointestinal cancer.

Herbal preparations use in prevention and treatment of gastrointestinal and hepatic disorders-Data from Vojvodina, Serbia. Complement Ther Med 2019; 43:265-270. [PMID: 30935541 DOI: 10.1016/j.ctim.2019.02.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2018] [Revised: 01/21/2019] [Accepted: 02/26/2019] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVE Gastrointestinal (GI) disorders are estimated to be frequent among general population. Various types of traditional and complementary therapies, primarily phytotherapy, can be used for prevention and treatment of many diseases and conditions, including GI complaints. Thus, the aim of this study was to investigate the patterns of use of medicinal herbs in treatment and prevention of GI disorders, together with their efficacy and safety. METHODS A prospective, repeated cross-sectional, descriptive study was conducted in the form of a specifically created questionnaire, filled in by consumers and/or patients in pharmacies on the territory of Autonomous Province of Vojvodina, Republic of Serbia. All data were statistically analyzed in Microsoft Excel 2007. RESULTS In the total number of 1137 patients, 10.4% declared themselves as consumers of phytopreparations for GI disorders. The most common diseases were constipation (44%) and dyspepsia (23%). The most frequently used preparations contained laxatives (with both anthraquinones and dietary fibers), artichoke and silymarin. Iberogast® was also frequently used. Pharmacists were the main source of recommendation for the most adequate herbal remedies. At the same time, phytopreparations were well tolerated, with no major side effects, and were evidently or presumably effective. CONCLUSIONS Some mild and moderate GI disorders seem to be treated frequently with phytopreparatons. Various herbal remedies are well accepted by patients, and the phytopreparations seem to have favorable ratio of safety and efficacy. Further integration into conventional medicine will improve the quality of the products used and provide a rational plan of use of medicinal plants.

Abstract
Humans swallow a great variety and often large amounts of chemicals as nutrients, incidental food additives and contaminants, drugs, and inhaled particles and chemicals, thus exposing the gastrointestinal tract to many potentially toxic substances. It serves as a barrier in many cases to protect other components of the body from such substances and infections. Fortunately, the gastrointestinal tract is remarkably robust and generally is able to withstand multiple daily assaults by the chemicals to which it is exposed. Some chemicals, however, can affect one or more aspects of the gastrointestinal tract to produce abnormal events that reflect toxicity. It is the purpose of this chapter to evaluate the mechanisms by which toxic chemicals produce their deleterious effects and to determine the consequences of the toxicity on integrity of gastrointestinal structure and function. Probably because of the intrinsic ability of the gastrointestinal tract to resist toxic chemicals, there is a paucity of data regarding gastrointestinal toxicology. It is therefore necessary in many cases to extrapolate toxic mechanisms from infectious processes, inflammatory conditions, ischemia, and other insults in addition to more conventional chemical sources of toxicity.

Abstract
Tyzzer's disease is caused by Clostridium piliformes and affects a wide range of domestic and wildlife species. Non-descript signs, if any, and a short incubation period make Tyzzer's disease difficult to diagnose and treat before death occurs. Here we describe an unexpected outbreak of Tyzzer's disease in a colony of native Australian spinifex hopping-mice (Notomys alexis). In this study captive hopping-mice were used in a nutrition trial (n=11), and others were housed in close proximity (n=4). During the nutrition trial, two hopping-mice exhibited signs of lethargy and diarrhoea, and were removed from the trial but died soon after. Other hopping-mice exhibited limited clinical signs of ill-health, prior to their death. In total four animals were found dead, and another seven were euthanised, to prevent a potential disease outbreak. Tyzzer's disease was confirmed post-mortem using histopathology silver stain to detect the bacilli-shaped bacteria (C. piliformes) in liver tissue of two hopping-mice. After Tyzzer's disease was confirmed enhanced infection control measures were implemented. Enhanced control measures included the use of metal containers for food and water, sick animals were fed and cleaned last, 5% sodium hypochlorite was used as the cleaning agent, stricter hand washing protocols and a change of gloves between feeding animals, and strict limits on persons entering the facility. Control measures for this disease should include euthanasia of any animals suspected to be infected, complete disinfection of all enclosures and associated equipment using sodium hypochlorite. Molecular methods could be employed to ensure complete removal of bacterial spores prior to new animals being moved into enclosures where affected animals were housed. Tyzzer's disease is a fast spreading disease which can cause detrimental effects to captive colonies and their environment. Captive colonies subjected to stress are at risk of Tyzzer's disease. Appropriate quarantine procedures, close montoring and quick action in response to signs of illness will ensure Tyzzer's disease outbreaks do not occur.

Abstract
The hydroethanolic root extract of Arrabidaea brachypoda, from Bignoniaceae family, a Brazilian medicinal plant, demonstrated significant in vivo gastroprotective effects using different in vivo assays. The activity was evaluated in several models of experimental gastric ulcer in rats (absolute ethanol, glutathione depletion, nitric oxide depletion, non-steroidal anti-inflammatory drugs, pylorus ligation and acetic acid). Using 300 mg/kg (p.o.) the extract significantly reduced gastric injury in all models. In depth phytochemical investigation of this extract led to the isolation of two previously undescribed phenylethanoid glycosides derivatives and seven unusual glycosylated dimeric flavonoids. The structures were elucidated using UV, NMR and HRMS analysis. Absolute configuration of the dimeric flavonoids was performed by electronic circular dichroism (ECD) spectroscopy.

Investigation of omeprazole and phenacetin first-pass metabolism in humans using a microscale bioreactor and pharmacokinetic models. Biopharm Drug Dispos 2015; 36:275-93. [PMID: 25678106 DOI: 10.1002/bdd.1940] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2014] [Revised: 01/20/2015] [Accepted: 01/31/2015] [Indexed: 12/30/2022]
Abstract
A new in vitro microfluidic platform (integrated insert dynamic microfluidic platform, IIDMP) allowing the co-culture of intestinal Caco-2 TC7 cells and of human primary hepatocytes was used to test the absorption and first-pass metabolism of two drugs: phenacetin and omeprazole. The metabolism of these drugs by CYP1A2, CYP2C19 and CYP3A4 was evaluated by the calculation of bioavailabilities and of intrinsic clearances using a pharmacokinetic (PK) model. To demonstrate the usefulness of the device and of the PK model, predictions were compared with in vitro and in vivo results from the literature. Based on the IIDMP experiments, hepatic in vivo clearances of phenacetin and omeprazole in the IIDMP were predicted to be 3.10 ± 0.36 and 1.46 ± 0.25 ml/min/kg body weight, respectively. This appeared lower than the in vivo observed data with values ranging between 11.9-19.6 and 5.8-7.5 ml/min/kg body weight, respectively. Then the calculated hepatic and intestinal clearances led to predicting an oral bioavailability of 0.85 and 0.77 for phenacetin and omeprazole versus 0.92 and 0.78 using separate data from the simple monoculture of Caco-2 TC7 cells and hepatocytes in Petri dishes. When compared with the in vivo data, the results of oral bioavailability were overestimated (0.37 and 0.71, respectively). The feasibility of co-culture in a device allowing the integration of intestinal absorption, intestinal metabolism and hepatic metabolism in a single model was demonstrated. Nevertheless, further experiments with other drugs are needed to extend knowledge of the device to predict oral bioavailability and intestinal first-pass metabolism.
