Spondias mombin L. (Anacardiaceae) has a worldwide distribution and is present in all regions of Brazil. Its leaves, flowers and bark are used as teas in folk medicine to treat diseases of the digestive system. This study aimed to evaluate the acute non-clinical toxicity, gastroprotective activity, and the related mechanisms of action of nebulized extract and tablets based on dried Spondias mombin (SmNE). SmNE screening showed the presence of flavonoids (0.65%), polyphenols (25.50%), where the major compound is gallic acid. In the acute oral toxicity assay, a dose of 2000 mg/kg of SmNE administered orally in Swiss mice did not induce any behavioral changes. SmNE (250 or 500 mg/kg p.o) significantly reduced the ulcerative lesion area when compared to the control group in ethanol and non-steroidal anti-inflammatory drug (NSAIDs) models. Results showed that treatment with SmNE (250 mg/kg) reduced acid secretion and gastric content, accompanied with an increase in pH. Previous administration of indomethacin and glibenclamide reversed the protection provided by SmNE, confirming the participation of prostaglandins (PGs) and ATP-sensitive potassium channels (KATP) in its gastroprotective effect. The SmNE tablets met the pharmacopeial quality requirements with gastroprotective activity and similar protection in comparison to the isolated extract administrated. In conclusion, SmNe has a gastroprotective activity related to cytoprotective mechanisms, such as the participation of endogenous prostaglandins and KATP channels, having an anti-secretory effect with systemic action. The formulation obtained presented gastroprotective effects similar to the administration of the extract, the tablets showed favorable compression characteristics by the direct route and met the pharmacopeial quality requirements.

This study aimed to investigate hepatoprotective and anti-inflammatory activities of the hydro-alcoholic extract of Oxalis debilis (ODHE) leaves. Acute oral toxicity evaluated ODHE in graded oral doses (100, 500, 1000, 3000, and 5000 mg/kg body weight) in rats. The hepatoprotective activity was evaluated in CCl4 intoxicated rats at 200 and 400 mg/kg body weight doses of ODHE, while anti-inflammatory activity was determined by carrageenan-induced paw edema in rats at 200, 400, 800 mg/kg body weight doses of ODHE. The ODHE was safe at the highest dose of 5000 mg/kg in experimental rats. In hepatoprotective activity, ODHE significantly reduced the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin (TB) levels as compared to the CCl4control group. On the other hand, ODHE showed an anti-inflammatory effect similar to that of the control group in the carrageenan-induced paw edema model. The histopathological findings showed a significant difference between the ODHE (400 mg/kg) and CCl4 groups. The present experiment showed that ODHE has significant hepatoprotective and anti-inflammatory activities. Results confirm the use of O. debilis in folk medicine in the treatment of hepatotoxicity and inflammation.

The medicinal plant Sphagneticola trilobata native to South America is used in local folk medicine to treat inflammation and analgesics. In present study, gastroprotective effects of methanolic extracts of S. trilobata leaves and stem were investigated in indomethacin-induced gastric ulcers in rats at doses of 200 mg/kg for leave extract and 350 mg/kg for stem extract. Indomethacin produced stomach ulcers and increased neutrophil percentage and MDA levels compared to the control group (p < 0.001). Co-administration of indomethacin and omeprazole, methanolic extracts of leaves (200 mg/kg) (p < 0.001) and methanolic extracts (350 mg/kg) (p < 0.05) of stem compared to indomethacin group to ulcers was low (p < 0.001). Methanolic extracts (200 mg/kg) of leaves and methanolic extracts (350 mg/kg) of stem reduced MDA levels (p < 0.001). Methanolic extracts (200 mg/kg) of leaves and methanolic extracts (350 mg/kg) of the stem significantly decreased neutrophil percentage compared to indomethacin group (p < 0.001). The results suggest that the methanolic extracts of Sphagneticola trilobata leaves and stem have a protective effect on indomethacin-induced gastric ulcers.

Chronic Coronary Heart Disease

To evaluate possibilities of aspirin-induced gastroduodenopathy treatment in the patients with chronic ischemic heart disease by means of applying the internal endogenous prostaglandins stimulant.  Material and methods. 340 patients suffering from chronic coronary heart disease and receiving a long-term acetylsalicylic acid (ASA) therapy were examined on the base of the cardiovascular care unit of The Nizhny Novgorod Regional Clinical Hospital named after N.A. Semaschko. There were evaluated frequency, nature and severity of the aspirin-induced gastroduodenopathy. The patients with coronary heart disease and aspirin-induced gastroduodenopathy were divided in two groups. In the first group of patients there was applied rebamipide therapy (in a single daily dose 300 mg) in combination with the proton pump inhibitor (PPI) — pantoprazole. In the second group there was applied only pantoprazole therapy. For the purpose of specification of AIG pathogenetic mechanisms development, all the examined chronic coronary heart disease cases were tested on the prostaglandin E2 (PGE2) level in blood serum before the therapy beginning and after the treatment. The control group was formed of chronic coronary heart disease patients showing no AIG evidence. Statistical processing of the received data was fulfilled with the program «Statistika 10.0». Results. AIG was registered in 15% out of 340 chronic coronary heart disease patients. According to the endoscopic examination erosive disease of the body and antrum prevailed among the patients. The PGE2 level in the blood serum was significantly lower (р = 0,00087) in these patients in comparison with the control group. In association with PPI and rebamipide mixed therapy, esophagogastroduodenoscopy results showed no pathological findings in gastrointestinal mucosa and statistically significant (р = 0,00067) blood serum PGE2 level growing in all the treated patients. As a result of exclusive PPI therapy there was marked positive dynamics in endoscopic view in 19 out of 25 patients and a tendency to normalization of PGE2 level in the blood serum. However, PGE2 level growing was insignificant. Conclusion. The presented research demonstrates the possibility of AIG treatment with the use of internal endogenous prostaglandins stimulant — rebamipide in complex with proton pump inhibitor PPI therapy.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

ABSTRACT: Canine monocytic ehrlichiosis (CME) is an infectious disease caused by the bacterium Ehrlichia canis and transmitted by Rhipicephalus sanguineus sensu lato, a tick with worldwide distribution. When not diagnosed and treated early, disease can be severe. Currently, the disease is confirmed by serological or molecular assays. The objective of this study was to compare a serological assay based on immunochromatography (SPEED® EHRLI immunochromatographic test; BVT, France) and a molecular assay (a screening PCR followed by a nested PCR specific for E. canis) for the diagnosis of E. canis in suspected dogs from Buenos Aires city and southern Greater Buenos Aires, Argentina. Blood samples from 20 clinically healthy dogs (Control Group) and from 80 sick dogs suspected of having CME (Groups 1 to 4) were tested in parallel. Neither the immunochromatographic test nor the PCR assay was able to detect the presence of E. canis in the Control Group. In the group which had been previously tested by serology, the agreement between the tests was low (kappa: 0.200), whereas in the group which had been previously tested by PCR, the concordance between the tests was adequate (kappa: 0.650). The concordance between the tests evaluated in the total population studied was moderate (kappa: 0.496). The results of our study suggest that the use of rapid serological tests as a first approach, together with subsequent confirmation by PCR, will improve the diagnosis of CME.

It has been reported that granulocyte-colony-stimulating factor(G-CSF) improves cardiac function after myocardial infarction (MI). However, its direct effect on the myocardium and its signaling pathway remain unclear. We examined the acute beneficial effect of G-CSF on myocardial infarct size and its precise mechanisms in a rabbit model of myocardial infarction. In 80 Japanese white rabbits, MI was induced by 30 min of ischemia and 48 hours of reperfusion. Rabbits were intravenously injected with 10 μg/kg of G-CSF (G-CSF group, n=10) or saline (control group, n=10) immediately after reperfusion. The G-CSF+5HD group (n=10) was injected with 5-HD(5-hydroxydecanoate, a mitochondrial KATP channel blocker) 5 min before G-CSF injection. The G-CSF +wortmaninn group (n=10) was injected wortmaninn (0.6mg/kg) 5 min before G-CSF injection. G-CSF+L-NAME group (n=10) was injected with L-NAME (10mg/kg) 5 min before G-CSF injection. The 5HD alone (n=10), wortmannin alone (n=10), L-NAME alone (n=10) groups were respectively injected 5HD, wortmannin and L-NAME immediately after reperfusion. Myocardial infarct size was calculated as a percentage of the risk area of the left ventricle. Western blot analysis was performed to examine the Akt and phospho-Akt and phospho-eNOS in the ischemic myocardium at 48 hours of reperfusion. The infarct size was significantly smaller in the G-CSF group (26.7±2.7%) than in the control group (42.3±4.6%). The infarct size-reducing effect of G-CSF was completely blocked by 5-HD (42.5±1.66%), wortmaninn(44.7±4.81) and L-NAME (42.1±4.2%). Wortmannin, L-NAME or 5HD alone did not affect the infarct size. Western blotting showed higher expression of phospho-Akt and phosho-eNOS in the infarct area in the G-CSF group than in the control group. G-CSF administered immediately after reperfusion reduces myocardial infarct size via activation of PI3K, Akt, eNOS and opening the mitochondrial KATP channels.

Abstract Objectives “Bignay” (Antidesma bunius), “lipote” (Syzygium polycephaloides) and “duhat” (Syzgium cumini) are indigenous berries in the Philippines that are known to contain high antioxidant properties and other health-promoting and disease-preventing compounds. However, oral toxicity studies on these berries are not yet explored. Hence, this study evaluated the acute oral toxicity of these berries in freeze-dried forms using 6-week old ICR mice following the OECD guidelines 425 (up and down method). Methods Treatment groups were administered with freeze-dried powders of “bignay”, “lipote” and “duhat” reconstituted in distilled water at various doses: 55 mg/kg body weight (BW), 175 mg/kg BW, 550 mg/kg BW, 2000 mg/kg BW and 5000 mg/kg BW while control group was administered with distilled water. Body weight, feed and water intake were obtained daily. Biochemical profiles were measured prior to administration of reconstituted berries at day 1 and prior to euthanasia. Toxicity, morbidity and mortality cases were observed daily. Euthanasia and necropsy were performed to check for gross organ abnormalities. Results Mice that received the different concentrations of “bignay”, “lipote” and “duhat” had normal feed and water consumption and gained weight during the test period. No clinical and behavioral signs of toxicity were observed and there was zero morbidity and mortality. Post-mortem evaluation showed no lesions on various organs examined. Blood ALT, BUN and creatinine levels were within normal published values. Conclusions These results show that different concentrations of freeze-dried “bignay”, “lipote” and “duhat” are non-toxic using ICR mice and therefore have high potential to be developed into food supplements and nutraceuticals.

Studies on the safety of herbal medicine are essential for the development of new drugs. The aim of this study was to evaluate the no-observed-adverse-effect-level (NOAEL) of HVC1 (Gamisamhwangsasim-tang, a 30% ethanol extract of a mixture of Pruni Cortex, Scutellariae Radix, Coptidis Rhizoma, and Rhei Rhizoma) and identify its target organs after oral administration to Sprague-Dawley (SD) rats repeatedly for 13 weeks. Three test groups were treated with HVC1 at a dose of either 500 (low-dose), 1,000 (middle-dose), or 2,000 (high-dose) mg/kg/day. Another group received high-dose HVC1 and was observed for 4 weeks following treatment to examine recovery from the effects of the extract. All treatment groups were compared to a vehicle control group. During the study, mortality, clinical signs, body weight changes, food consumption, abnormal lesions in the eye, urinary parameters, hematological parameters, blood coagulation time, blood biochemical parameters, changes in organ weight, gross findings, and histopathological changes were examined. No systemic toxicity related to HVC1 was observed in any group, and it was concluded that the NOAEL of HVC1 was 2,000 mg/kg/day. No target organ was identified.
