Authors:

Abstract and Figures

In this study, the in vitro effect of Rosmarinus officinalis L. (Rosemary) aqueous extract on rat gastric acid secretion was investigated. 24 male Sprague Dawley male rats were used in the study. Rats were euthanized by cervical dislocation in the presence of ketamine hydrochloride (Ketalar: 75 mg / kg) and xylazine (Rompun: 15 mg / kg) anesthesia. The isolated stomachs were left in the isolated organ bath for 1 hour for the incubation period. At the end of this period, the pH of the mucosal fluid obtained from the stomachs was evaluated as the basal pH. Histamine was then applied to the bath environment to induce stomach acid secretion and the pH values of the stomach contents were measured. Four different doses of Rosemary extract (150, 300, 600 and 1200 μg / ml) were applied to the bath separately and the pH of the stomach contents was recorded. In addition, Rosemary Extract's four separate doses were applied to the individual baths with Histamine and the pH values of the stomach contents were determined. The resulting pH values were compared to the basal pH and the ΔPH values were calculated. In conclusion, the effect of 150 μg / ml dose of Rosemary extract on gastric acid secretion was not statistically significant and doses of 300, 600 and 1200 μg / ml increased stomach acid secretion statistically significantly

Carbon tetrachloride (CCl4) is an environmental pollutant that showed toxicity in different organs. Exposure to CCl4 is known to induce the formation of reactive oxygen species (ROS). Rosemary (Rosmarinus officinalis) is a herb commonly used as spice and flavoring agents in food processing and is useful in treatment of many diseases. The purpose of present study was to investigate the protective role of rosemary on CCl4-induced renal damage. Treating rats with 1.0ml /kg body weight of 10% CCl4 twice a week for 6 weeks induced many histological changes in the kidney cortex. The renal tubules lost their characteristic appearance and their lining epithelial cells were degenerated. The glomeruli were atrophied and the renal blood vessels were congested. The intertubular spaces were infiltrated by inflammatory leucocytic cells. An increase in interstitial expression of α-SMA was observed compared with control group. CCl4 also caused marked elevation in serum creatinine and urea. Treating animals with CCl4 and aqueous extract of rosemary led to an improvement, in both biochemical and histopathological pictures. It is concluded that rosemary extract had a protective effect against kidney injury induced by CCl4 and this effect may be attributed to its antioxidant activity.

There is more and more interest in caper (Capparis spinosa) in recent years as it has different areas to be applied especially within the food and cosmetic world. This study evaluated the in vitro antioxidant activity of water and ethanol extracts of capsules of caper (Capparis spinosa). The antioxidant properties of the caper were evaluated in vitro by antioxidant assays such as 2-azino-fcw(3-ethylbenzthiazoline-6- sulfonic acid) (ABTS) radical scavenging, l,l-diphenyl-2-picryI-hydrazyl free radical (DPPH*) scavenging, total antioxidant activity by ferric thio- cyanate method, total reductive capability using the potassium ferri- cyanide reduction method, superoxide anion radical scavenging and metal chelating activities. aα-Tocopherol, butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) were used as the reference antioxidant compounds. The concentration of 10,30 and SO uμg/mL of water and ethanol extracts of caper showed 95.9, 96.4, 97.0, 97.04, 97.4, 94.8 % inhibition on peroxidation of linoleic acid emulsion, respectively. On the other hand, 30 uμg/mL of standard antioxidant such as aα-tocopherol indicated an inhibition of 88.1 % on peroxidation of linoleic acid emulsion. In addition capper is an effective ABTS + scavenging, DPPH' scavenging, superoxide anion radical scavenging, total reducing power and metal chelating on ferrous ions activities.

The digestive function of the stomach depends on acidification of the gastric lumen. Acid secretion into the lumen is triggered by activation of PKA cascade, which ultimately results in the insertion of gastric H,K-ATPases into the apical plasma membranes of parietal cells. A coupling protein is ezrin whose phosphorylation at Ser66 by PKA is required for parietal cell activation. However, little is known regarding the molecular mechanism(s) by which this signaling pathway operates in gastric acid secretion. Here we show PKA cooperates with MST4 to orchestrate histamine-elicited acid secretion by phosphorylating ezrin at Ser66 and Thr567, respectively. Histamine stimulation activates PKA which phosphorylates MST4 at Thr178 and then promotes MST4 kinase activity. Interestingly, activated MST4 then phosphorylates ezrin pre-phosphorylated by PKA. Importantly, MST4 is important for acid secretion in parietal cells because either suppression of MST4 or overexpression of non-phosphorylatable MST4 prevents the apical membrane reorganization and proton pump translocation elicited by histamine stimulation. In addition, overexpressing MST4 phosphorylation-deficient ezrin results in an inhibition of gastric acid secretion. Taken together, these results define a novel molecular mechanism linking PKA-MST4-ezrin signaling cascade to polarized epithelial secretion in gastric parietal cells.

Nigella sativa (NS) has been shown to have antioxidant, anti-infl ammatory and antiulcer activities in diff erent conditions. The present work was done to investigate the possible eff ects of Nigella sativa aqueous extracts (NS) on gastric acid secretion in isolated rat stomach. Gastric acid secretion was measured in the isolated rat stomach preparation. The results obtained in vitro experiments showed that doses of 2 mg/100 ml DMSO and 5 mg/100 ml DMSO of NS aqueous extracts reduced gastric acid secretion stimulated by histamine and 5 mg/100 ml DMSO of NS aqueous extracts reduced gastric acid secretion stimulated by bethanechol, but none of the doses of NS did aff ect pentagastrin-induced acid secretion. The present results suggest that NS has a gastroprotective eff ect, probably due to reducing gastric acid secretion.

The present study examined the effect of water extract (200 mg/kg body weight) of Rosmarinus officinalis L. in streptozotocin (STZ)-induced diabetic rats for 21 days. The hepatoprotective effects were investigated in the liver tissues sections. There was a significant increase in serum liver biochemical parameters (aspartate aminotransferase, alanine transaminase, and alkaline phosphatase), accompanied by a significant decrease in the level of total protein and albumin in the STZ-induced rats when compared with that of the normal group. The high-dose treatment group (200 mg/kg body wt) significantly restored the elevated liver function enzymes near to normal. This study revealed that rosemary extracts exerted a hepatoprotective effect. The results indicate that the extract exhibits the protective effect on tissues and prove its potentials as an antidiabetic agent.

Objective: Since the description of ECL cell-derived tumors in rodents after long-term profound acid inhibition inducing hypergastrinemia, there has been concern that proton pump inhibitors (PPIs) could also do that in man. The recent description of a Spanish family with gastric ECL cell tumors at the age of about 30 years secondary to a defect in the proton pump due to mutation in the ATP4A gene clearly shows that hypergastrinemia alone also is sufficient to induce ECL cell neoplasia in man. The present review aims to evaluate the risk of gastric neoplasia secondary to gastric acid inhibition. Methods: Literature (MEDLINE) was searched for the role of the ECL cell in gastric carcinogenesis in animals and man in general and particularly secondary to long-term inhibition of acid secretion. Results: An important proportion of patients treated with PPI develops hypergastrinemia causing ECL cell hyperplasia and the first descriptions of ECL cell carcinoids secondary to PPI have been reported. The role of the ECL cell has hitherto been under estimated in gastric carcinogenesis in man where for instance the signet ring cell type of gastric carcinoma seems to originate from the ECL cell. Conclusions: The first two of three steps in rodent ECL cell carcinogenesis (hyperplasia, carcinoid, and carcinoma) secondary to PPI dosing, have been described for man. It is every reason to believe that the final step, gastric carcinoma, will develop also in man. Clinical decisions should be based not only on so-called evidence based medicine, but also on physiological knowledge and animal studies.

Opinion statement: Hypersecretory conditions affecting the stomach account for significant morbidity and mortality manifested in some cases with peptic ulcer, gastrointestinal hemorrhage, and/or gastroesophageal reflux disease (GERD). The diagnosis of gastric acid hypersecretory states can be challenging and relies on the use of quantitative assays to measure gastric acid secretion and serum gastrin. The most common etiology for hypergastrinemia is the use of potent gastric acid inhibitors such as the proton pump inhibitors. The differential diagnosis of this condition is of critical importance, and will dictate management decisions. Conditions such as atrophic gastritis are relatively benign and can lead to hypergastrinemia without the presence of gastric acid hypersecretion. Zollinger-Ellison syndrome, on the other hand, causes hypergastrinemia with profound gastric acid hypersecretion [1]. More common causes of hypergastrinemia include gastric outlet obstruction, ileus, and chronic renal failure [2]. In most cases, proton pump inhibitors will be used to manage these conditions. In some instances, surgical therapy may be required. This chapter will review the important clinical causes of gastric acid hypersecretion and provide insights to the best medical management options to better care for patients with these disorders.

Histamine is a developmentally highly conserved autacoid found in most vertebrate tissues. Its physiological functions are mediated by four 7-transmembrane G protein-coupled receptors (H1R, H2R, H3R, H4R) that are all targets of pharmacological intervention. The receptors display molecular heterogeneity and constitutive activity. H1R antagonists are long known antiallergic and sedating drugs, whereas the H2R was identified in the 1970s and led to the development of H2R-antagonists that revolutionized stomach ulcer treatment. The crystal structure of ligand-bound H1R has rendered it possible to design new ligands with novel properties. The H3R is an autoreceptor and heteroreceptor providing negative feedback on histaminergic and inhibition on other neurons. A block of these actions promotes waking. The H4R occurs on immuncompetent cells and the development of anti-inflammatory drugs is anticipated. Copyright © 2015 by The American Society for Pharmacology and Experimental Therapeutics.

Nordic research on physiology and pathophysiology of the upper gastrointestinal tract has flourished during the last 50 years. Swedish surgeons and physiologists were in the frontline of research on the regulation of gastric acid secretion. This research finally led to the development of omeprazole, the first proton pump inhibitor. When Swedish physiologists developed methods allowing the assessment of acid secretion in isolated oxyntic glands and isolated parietal cells, the understanding of mechanisms by which gastric acid secretion is regulated took a great step forward. Similarly, in Trondheim, Norway, the acid producing isolated rat stomach model combined with a sensitive and specific method for determination of histamine made it possible to evaluate this regulation qualitatively as well as quantitatively. In Lund, Sweden, the identification of the enterochromaffin-like cell as the cell taking part in the regulation of acid secretion by producing and releasing histamine was of fundamental importance both physiologically and clinically. Jorpes and Mutt established a center at Karolinska Institutet in Stockholm for the purification of gastrointestinal hormones in the 1960s, and Danes followed up this work by excelling in the field of determination and assessment of biological role of gastrointestinal hormones. A Finnish group was for a long period in the forefront of research on gastritis, and the authors' own studies on the classification of gastric cancer and the role of gastrin in the development of gastric neoplasia are of importance. It can, accordingly, be concluded that Nordic researchers have been central in the research on area of the upper gastrointestinal physiology and diseases.

Aim: Carnosic acid (CA) inhibits adipogenesis in vitro. The present study evaluated the therapeutic effects of CA in ob/ob mice. Methods: The experimental animals were given a standard chow diet with or without CA for 5 weeks. Bodyweight gain and food intake were measured during this period. Magnetic resonance imaging analysis, histological examination, serum chemistry analysis and intraperitoneal glucose tolerance test (IPGTT) were all performed. Results: The mice fed CA experienced significant weight loss and reduced visceral adiposity, in addition to significantly reduced serum triglyceride (TG) and cholesterol levels. Importantly, CA had a dramatic effect on the liver by reducing the hepatic TG content, thus decreasing serum alanine aminotransferase levels. In addition, IPGTT revealed that CA significantly improved glucose tolerance. Conclusion: These data suggest that CA is a novel therapeutic agent for obesity-related non-alcoholic fatty liver disease.
