Gastric ulcer has shown association with changes in sex hormones, with impact exacerbated in males. Also, males are known to be more exposed to ulcer risk factors. This study investigates the effect of testosterone on indomethacin induced gastric ulcers in adult female rats. Eighteen female rats (225 ± 25 g body weight) were randomly assigned to 3 groups under standard laboratory condition. After acclimatization, animals fasted for 40 hrs but were given water ad libitum. Group A served as control while group B served as the ulcer control, in which ulcer was induced without treatment using indomethacin (40 mg/kg single orally dose). Group C was pretreated with testosterone (1 mg/kg IM) eight hours before ulcer induction. Eight hours after ulcer induction, animals were sacrificed and the stomach was harvested for analysis. Results showed a significant reduction in mucus content in groups C (0.79±0.11 g) and B (0.87±0.02 g) compared to A (1.11±0.03 g). Gastric mucus pH was significantly acidic in group B (4.40±0.55) compared to C (5.20±0.45) and A (5.80±0.45). There was a significantly higher ulcer index in group B (4.60±0.55 mm) compared to C (3.60±0.89 mm) and testosterone pretreatment resulted in a 21.74% ulcer inhibition. Although weak, the findings suggest that testosterone might protect the gastric mucosa against NSAIDs in females.

Mental stress, such as anxiety and conflict, causes physiological changes, such as changes in autonomic nervous activity and gastric ulcers. In addition, stress induces glucocorticoids and changes the hippocampal brain-derived neurotrophic factor (BDNF) expression levels. We previously reported that Acanthopanax senticosus HARM (ASH) prevents stress-induced gastric ulcers. Thus, we investigated the potential anxiolytic effect and influence of ASH on the hippocampus BDNF-related protein in male Sprague-Dawley rats fed 1% and 5% ASH extract-containing food for one week using novelty suppressed feeding (NSF) and improved elevated beam walking (IEBW) tests. ASH treatment significantly decreased latency to eat in the NSF test and increased the time spent on the open arm in the IEBW test. ASH5% treatment showed a significant decrease in LFnu, indicative of sympathetic nervous activity, and a significant increase in HFnu, indicative of parasympathetic nervous activity, in the NSF test. In addition, ASH1% and ASH5% treatments significantly decreased LFnu and significantly increased HFnu in the IEBW test. ASH5% treatment significantly increased hippocampal BDNF protein expression in both Western blotting and immunohistochemistry experiments. Our findings suggest that anxiolytic effects of ASH occur via the regulation of autonomic function and increased hippocampal BDNF signaling.

Restraint of different strains of rat has been shown to be capable of inducing both oral and gastric ulcers. Hooded Wistar rats were most susceptible to gastric ulcers, whereas Sprague-Dawley rats had the highest incidence of oral ulcers. The causative mechanisms probably differ and are strain dependent.

Background: Euphorbia nivulia Buch.-Ham (En) is one of the members of Euphorbiaceae family that is rich in phytochemicals including flavonoids, triterpenes and polyphenolics. Purpose: To evaluate hepato-nephronprotective potential of Euphorbia nivulia. Study Design: Sprague Dawley rats were used as animal models in the study. Methods: En hydro alcoholic extract was standardized and managed in high dose (300 mgkg−1 body weight (BW) and low dose  (150 mgkg−1 BW) to Sprague Dawley rats, administered with CCl4 (1mlkg−1BW). Silymarin (50 mgkg−1 BW) was taken as positive control. The treatments were given thrice a week. Consequently, blood and hepatic homogenates were collected after 4 weeks of treatment. While the situation of kidney was explored through measurement of serum creatinine, serum urea, sodium and albumin levels. Hepatic and renal samples of rats treated with both 150 and 300 mg/kg of the extract were used for tissue pathological study. Results: En extract revealed dose dependent moderate level of shelter against CCl4 intoxicated hepato-nephrotoxicity as directed from the acquired results. The decrease of the albumin levels by the maximum dose of the extract exceeded similar to that attained with Silymarin, and the protecting effects of the extract against oxidative destruction were evaluated. Examination of serum show significant (p < 0.05) elevation in the level of aspartate transaminase(AST), alkaline phosphatase(ALP), alanine transaminase(ALT), whereas decline were noted for albumin in CCl4 treated rats. Histopathological cuts and damages were seen in hepatic cells and kidney of rats managed by CCl4. But, co-administration of En extract, dose dependently, improved the CCl4-carried hepatic harms in these limits. Conclusion: These effects propose that the phyto-ingredients of En extract with known polyphenols were able to improve the oxidative stress brought along with CCl4 and may be a useful healing mediator to manage oxidative stress related disorders like hepato-nephro toxicity.

Melissa officinalis is a plant that has been widely used as an herbal medicine in many countries. Unfortunately, despite the prevalent medicinal uses of the plant, there are no reports on the possible toxic effects of M. officinalis. This study was designed to evaluate the effect of long-term administration of hydro-alcoholic extract of M. officinalis on some biochemical and hematological parameters and histopathology of organs. Thirty Sprague-Dawley rats were allocated to three equal groups. The animals in groups A and B received 600 and 1200 mg/kg M. officinalis extract, respectively, for 30 days. The rats in group C were given gavaged saline as control. The animals were euthanized at the end of experiment and the blood samples were collected for biochemical and hematology analysis. Additionally, appropriate tissue samples were collected from kidney, liver, spleen, heart and lung for light microscopic examination. M. officinalis caused a significant increase in the alanine aminotransferase level in the treated rats. Although the increase in creatine phosphokinase and lactate dehydrogenase levels were observed in group A and B, respectively, but there were no significant differences. A significant decrease was observed in the total protein and albumin concentrations in serum of treated rats as compared to the control group. The creatinine concentrations were significantly higher in the group B when compared to the other groups. There were no significant differences in cholesterol, triglyceride and urea concentrations between all groups of rats. The main histopathologic findings in the liver were included hepatocyte degeneration, congestion and dilation of sinusoids, proliferation of bile ducts and infiltration of mononuclear cells around the portal area. Histopathologic examination of the kidneys showed a tubular degeneration and necrosis, tubular and glomerular atrophy and congestion. These lesions were more prominent in the high dose treated rats. The findings suggest that long-term administration of M. officinalis extract even at low doses induces hepatic and renal lesions in rats.
