Abstract B-FOS (butyl-fructooligosaccharide) is a newly synthesized prebiotic molecule, formed by the combination of FOS and butyrate by ester bonds. B-FOS has been reported to have the potential prebiotic effect of promoting intestinal flora diversity and enhancing butyrate production. The aim of this study was to investigate the potential acute and sub-chronic toxicity of B-FOS in Institute of Cancer Research (ICR) mice and Wistar rats to verify its biosafety. ICR mice were administered a single oral gavage of B-FOS at doses of 0, 500, 1000, and 2000 mg/kg body weight and observed for signs of acute toxicity for 14 days. Sub-chronic toxicity was evaluated by repeated oral administration of B-FOS at 2000 mg/kg for 28 days, in accordance with Organization for Economic Co-operation and Development (OECD) protocol test numbers 420 and 407. No mortality or abnormal clinical signs were observed during the experimental periods after B-FOS administration. Furthermore, no significant changes in body weight, organ weight, serum biochemical parameters, or tissue histology were observed after animal sacrifice. These in vivo results indicate that B-FOS does not exert any acute or sub-chronic toxicity at a dose of 2000 mg/kg, and this novel molecule can be regarded as a safe prebiotic substance for use in the food and nutraceutical industries.

Objective: To investigate the effect of dexamethasone on spermatogonium and sertoli cell of ipsilateral testis in unilateral testicular torsion strain wistar rat. Material & Method: Experimental study with post-test only control group design. The present  study was conducted on 30 Wistar male rats aged 10 – 12 weeks grouped into 5 groups. Group I was the normal/sham operation group (KN), group II was left testicular torsion for 4 hours group and followed  by manual detorsion  (K1), group III was left testicular torsion for 10 hours group and followed  by manual detorsion (K2),  group IV was left testicular torsion for 4 hours group and given dexamethasone 10 mg/kg body weight subcutaneously 30 minutes before manual etorsion (D1), and group V was left testicular torsion for 10 hours group and  given dexamethasone 10 mg/kg body weight subcutaneously 30 minutes before manual detorsion. All rats had left orchidectomy 4 hours after detorsion. The number of spermatogonium and sertoli cells were counted in histological seminiferous tubular testis that have obtained Haematoxylin Eosin staining. Data were analyzed by ANNOVA followed by Post Hoc Tukey for spermatogonium and Kruskal Wallis followed by Mann Whitney test for sertoli cell. Differences were considered significant at p <0.05. Results: There was significant difference in the mean number of spermatogonium between K1 & D1 group. Otherwise, there was no significant difference in the mean number of spermatogonium between K2 & D2. There was significant difference in the mean number of Sertoli cells between K1 & D1 group, likewise that between K2 & D2 group. Conclusion: These results suggest that dexamethasone has protective effect in spermatogonium and sertoli cell in testicular torsion for 4 hours.

Anredera cordifolia or binahong is one of the Indonesian medicinal plants that is used to treat peptic ulcer. The purpose of this study was to evaluate the effect of the addition of sodium carboxymethylcellulose (CMC) and sorbitol on anti-peptic ulcer activity of A. cordifolia leaves extracts in male Wistar rats. The plants were extracted using decoction method and freeze dried. Three liquid formulas were used i.e., i) a combination of sodium CMC and sorbitol; ii) only sorbitol; iii) extract only. The rats were divided into 6 groups, i.e., positive control (sucralfate 35 mg/kg body weight); negative control (80% ethanol); normal control; and 3 formulas. After the administration of the liquid formula, all groups, except normal control, were given 80% ethanol (l5 ml/kg body weight) to induce peptic ulcer. Antipeptic ulcer activity was evaluated using direct observation on rats gastric mucosa, and histopathology assessment. The result showed that the strongest anti-peptic ulcer  was shown by sorbitol only (96.95% inhibition),  followed by the combination of sodium CMC and sorbitol (92.68% inhibition). The formula which only contained extract showed only  31.70% inhibition.  Statistical analysis showed significant differences between formula 1 and 2 with negative controls. In conclusion, A. cordifolia leaves extract with the addition of sorbitol showed the strongest anti-peptic ulcer activity. Keyword: Anredera cordifolia, peptic ulcer, suspense, Wistar rat.

Ficus vogelii is a medicinal plant mainly found in tropical Africa and reported to treat inflammatory complaints. This study aims to evaluate the acute and sub-chronic toxicity of the aqueous extract of Ficus vogelii stem bark in wistar rats. For acute study, aqueous extract at a single dose of 5000 mg/kg body weight was administered to female rats and observed for 14 days. In the sub-chronic study, the extract was administered daily to both sex rats at the doses of 100, 200, 400, and 600 mg/kg body weight for 28 consecutive days. Body weight was measured weekly, while hematological, biochemical, and histopathological parameters were analyzed after euthanize. Aqueous extract of Ficus vogelii at all tested doses didn’t produced any mortality or significant change on the body weight and relative weight of rats on acute and sub-chronic studies. The lethal dose 50 was estimated greater than 5000 mg/kg (DL50˃5000 mg/kg). Hematological parameters were recorded non-significant in all treated rats. Aqueous extract at 600 mg/kg significantly changed transaminases and alkaline phosphatase activities, these changes were reversible in satellites. The concentrations of bilirubin was increased at 200 and 600 mg/kg in male rats, at 100, 400 mg/kg in female rats. The levels of lipids markers didn’t changed, except the significant decrease of LDL-cholesterol. Histological examination didn’t showed any change in the architecture of the liver and kidney of rats treated compared to control. Thus aqueous extract of Ficus vogelii stem bark didn’t produced adverse effects in rats after oral acute and sub-chronic treatment.

CONTEXT: The cabbage (Brassica oleraceae var. capitata) is an herbaceous and leafy plant which belongs to the Brassicaceae family, native to coastal southern and Western Europe. Used in cooking for its nutritional value also has known anti-inflammatory activity. OBJECTIVE We studied the antiulcerogenic activity of aqueous extract of Brassica oleracea var. capitata (AEB) in order to validate ethnobotanical claims regarding the plant use in the gastric disorders. METHOD: Acute gastric ulcers were induced in rats by the oral administration of acetylsalicylic acid. The gastroprotective potential of the AEB (0.250, 0.500 and 1.000 mg.kg-1/body weight) was compared with omeprazole (20 mg.kg-1/body weight). RESULTS: The stomach analysis indicated that treatment with AEB inhibited the gastric damage. The gastroprotective activity as evidenced by its significant inhibition in the formation of ulcers induced by chemical agent with a maximum of 99.44% curation (250 mg.kg-1 body weight) in acetylsalicylic acid-induced ulcers. CONCLUSIONS: The AEB demonstrated good antiulcerogenic activities which justify the inclusion of this plant in the management of gastric disorders. Further experiments are underway to determine which antiulcer mechanisms involved in gastroprotection.

Traditional herbal medicine and their preparations have been widely used for thousands of years and are still in use in developing and developed countries owing to their medicinal values and their presumed relative safety. This belief that medicinal plants are not toxic or are with less side effect due to their natural origin is debatable; hence this study was conducted to evaluate the safety and (or) toxicity of Ethanol leaf extract of Simarouba glauca (EESG) on liver, kidney and heart functions of Wistar rats. The oral acute toxicity of EESG was evaluated in line with Lorke’s method. The sub-chronic toxicity of EESG was carried out according to the OECD guidelines with modification and using a total of twenty-four (24) male Wistar rats; divided into four groups of six rats each, following a two-week acclimatization. Test rats were orally administered EESG at doses of 500, 1000 and 2000 mg/kg body weight respectively daily for thirty (30) days, while the control was given only feed and water ad libitum. At the end of the experiment, the rats were fasted overnight and sacrificed under chloroform anesthesia; relevant biochemical and histopathology analyses were carried out. The data obtained from the oral acute test indicate that the LD50 was above 5000 mg/kg and there was no death recorded. There were significant increases (P ˂ 0.05) in percentage (%) body weight of rats administered respective doses of EESG. There were significant reductions (P˂0.05) in mean liver: body weight ratio of rats administered EESG 500 and 2000 mg/kg respectively, significant reductions (P˂0.05) in mean kidney: body weight ratios of rats given EESG 1000 and 2000 mg/kg respectively; significant reductions (P˂0.05) in mean heart: body weight ratios of test rats administered EESG 2000 mg/kg; whereas others were not significantly different (P˃0.05) relative to their respective control. Plasma ALT and GGT activities of rats administered respective dose of EESG were significantly reduced (P˂0.05); plasma ALP activities were significantly elevated (P˂0.05) relative to the control after 30 days. There were no significant differences (P˃0.05) in plasma total proteins and albumin levels. Plasma total and unconjugated bilirubin of rats administered respective dose of EESG were not significantly different (P˃0.05); whereas, rats given EESG recorded significant reduction in plasma conjugated bilirubin. Plasma urea was significantly elevated (P˂0.05) in rats administered EESG 1000 and 2000 mg/kg respectively. Test rats given EESG 500 and 1000 mg/kg respectively recorded significant elevations in plasma creatinine and rats given EESG 2000 mg/kg recorded significant decrease in plasma creatinine levels; others were not significantly different relative to the control. Plasma chloride and potassium ion levels of rats administered respective doses of EESG were not significantly different (P˃0.05); significant reduction (P˂0.05) in plasma sodium ions concentration in all group compared to the control. Plasma calcium ion levels in all group were not significantly different (P˃0.05); whereas there were significant reductions (P˂0.05) in plasma bicarbonate ion levels relative to their respective controls. Although plasma ALP activity were significantly elevated, there were no elevations in specific liver function enzymes and no visible hepatocellular damage. Furthermore, the conspicuous elevations observed in plasma urea and creatinine levels do not exclusively indicate EESG-induced organ injury. Therefore, it is suggestive that EESG was not significantly toxic to the to the liver, kidney and heart respectively and may be administered at lower doses in further studies.
