Objective: This study was designed to investigate the sub-acute toxicity profile of hydro-methanol extract of Burkea africana  (BA) stem bark in rats. Methods: The stem bark of BA was extracted by cold maceration using 80% methanol. Twenty female albino rats were randomly assigned into four groups of five rats each. Group 1 (only distilled water). Groups 2-4 received the extract (100, 200, and 400 mg/kg) orally, once daily for 28 days. The rats were observed for signs of toxicity and the bodyweight (b.wt) of rats taken weekly. Blood samples were collected on day 28 for hematology and serum chemistry. Visceral organs were harvested for organ-somatic index and histopathology. Results: There were no toxicity signs observed and no significant (p< 0.05) change in body weight but the pulmo-somatic index was significantly (p< 0.05) higher at 400 mg/kg compared with the control and other treated groups. Significant (p< 0.05) increase in PCV, RBC, and MCV and significant (p< 0.05) decrease in MCHC, Total WBC count, neutrophils and lymphocytes were observed. Also, there were significant (p< 0.05) decreases in ALT, total protein, globulin, total bilirubin of test groups when compared with the control group. Urea concentration of test groups significantly (p< 0.05) increased when compared with that of the control group. Conclusions: BA stem bark extract can be said to have no deleterious effect on erythrocyte, but rather serve to improve erythropoiesis and also has no overt toxic effect on the visceral organs. Also the extract may have immunosuppressive and oxidative tendencies on prolong use.                                   Peer Review History: Received 12 January 2021; Revised 3 February; Accepted 25 February, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

The purpose of this research is to evaluate the acute and subchronic toxicities of DA DAI TRANG HVD capsules through oral administration in experimental animals. The acute toxicity was determined by the method of Litchfield Wilcoxon in Swiss mice. The subchronic toxicity was evaluated by the recommendation of WHO and OECD in Wistar rats with oral doses of 1.44 g/kg/day (equal to recommended human dose) and 4.32 g/kg/day (3 times as high as recommended human dose) in 4 consecutive weeks. As a result, DA DAI TRANG HVD capsules at the highest dose used for mice (99.9 g materials/kg) did not express acute toxicity in mice. In term of the subchonic toxicity test, DA DAI TRANG HVD had no deleterious effect on hematological parameters, hepato-renal functions, macroscopic and microscopic images of livers and kidneys of rats. In conclusion, DA DAI TRANG HVD capsules did not produce the acute and subchronic toxicities in Swiss mice and Wistar rats.

This study investigated the toxicity profile of methanol extract of Hura crepitans leaf on albino rats. The up-and-down method at a dose limit of 2000 mg/kg was used in the oral acute toxicity test. Twenty-four (24) albino Wistar rats were randomly assigned to 4 groups (A –D, n = 6). Group A (control) received distilled water, while groups B-D received 100, 200 and 400 mg/kg of the extract, respectively. The rats were dosed once daily for 21 consecutive days and weighed weekly. Twenty-four hours after the last treatment on day 21, the rats were fasted overnight and blood was collected into EDTA and plain bottles for hematological evaluation and serum preparation respectively. A manual method was used to determine the full blood cell count, while Randox kit was used to estimate the serum markers of liver and kidney functions. The extract was tolerated by the rat; the LD50 was greater than 2000 mg/kg. At 21 days of treatment, the extract (100, 200 and 400 mg/kg) treated groups had 27.53, 25.98 and 25.33% weight gain respectively, while the distilled water treated group had 8.38% weight gain. The extract (200 and 400 mg/kg) reduced (p < 0.05) the packed cell volume, hemoglobin concentration and red cell count, serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase activities, but increased the total white blood cell in the treated groups when compared with the control group. This study suggests that methanol extract of Hura crepitans has hepatoprotective activity, promotes weight gain and could precipitate anemia when taken for a long period.

Abstract. Physical exercise increases free radicals production; antioxidant supplementation may improve the muscle fiber’s ability to scavenge ROS and protect muscles against exercise-induced oxidative damage. This study was designed to examine the effects of all-trans resveratrol supplementation as an antioxidant to mediate anti-oxidation and lipid per-oxidation responses to exercise in male Wistar rats. Sixty-four male Wistar rats were randomly divided into four equal number (n = 16) including training + supplement (TS), training (T), supplement (S) and control (C) group. The rats in TS and S groups received a dose of 10 mg/kg resveratrol per day via gavage. The training groups ran on a rodent treadmill 5 times per week at the speed of 10 m/min for 10 min; the speed gradually increased to 30 m/min for 60 minutes at the end of 12th week. The acute phase of exercise protocol included a speed of 25 m/min set to an inclination of 10° to the exhaustion point. Superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) activity, non-enzymatic antioxidants bilirubin, uric acid, lipid peroxidation levels (MDA) and the total antioxidant capacity (TAC) were measured after the exercise termination. The data were analyzed by using one-way ANOVA. The result showed that endurance training caused a significant increase in MDA level [4.5 ± 0.75 (C group) vs. 5.9 ± 0.41 nmol/l (T group)] whereas it decreased the total antioxidant capacity [8.5 ± 1.35 (C group) vs. 7.1 ± 0.55 mmol/l (T group)] (p = 0.001). In addition, GPx and CAT decreased but not significantly (p > 0.05). The training and t-resveratrol supplementation had no significant effect on the acute response of all variables except MDA [4.3 ± 1.4 (C group) vs. 4.0 ± 0.90 nmol/l (TS group)] (p = 0.001) and TAC [8.5 ± 0.90 (C group) vs. 6.6 ± 0.80 mmol/l (TS group)] (p = 0.004). It was concluded that resveratrol supplementation may prevent exercise-induced oxidative stress by preventing lipid peroxidation.

Our study compares the content in polyphenolic compounds and hypericin, in four species of Hypericum - H. perforatum L., H. maculatum Cr., H. hirsutum L., H. tetrapterum Fr. (syn. Hypericumacutum Mnch.) harvested from spontaneous flora in the north-western area of Transylvania, Romania. These species represent an important source of such compounds with different biological actions. After making the extracts, they were subjected to HPLC-SM analysis. The presence of rutoside in the largest amount (462.82 mg %) in the H. perforatum extract was observed, this containing most of the flavonoid heterosides. For the species H. maculatum, the presence in a much higher amount of the hyperoside (976.36 mg %) is characteristic compared to the other species. Quercetol is the best represented of the flavonoid aglycons, its concentration being the highest in H. hirsutum (659.66 mg %). The hypericin content ranges from 0.2171 g % in the H. tetrapterum extract, to 0.0314 g % in the methanol extract of H. maculatum.The highest antioxidant properties measured by FRAP method were recorded in the case of H. perforatum and H. maculatum.

Background: The incidence of cognitive decline has been proposed to rise exponentially in coming years. Therapies targeting molecular pathways involved in enhancement of memory and energy regulation could be a major breakthrough in prevention or management of dementia in susceptible populations. Objectives: This study investigated the effects of aqueous extracts of Cola nitida (AECONS) and Garcinia kola (AEGAK) on glutamate level and Na+/K+-ATPase activity in the hippocampus and hypothalamus of male Wistar rats. Methods: Adult male Wistar rats (170-200) were randomly allotted into groups (n=5/group); control (distilled water p.o.), AECONS1 (200 mg/kg), AECONS2 (400 mg/kg), AEGAK1 (200 mg/kg), AEGAK2 (400 mg/kg), AECONS1+AEGAK1 and AECONS2+AEGAK2. The extract was prepared and the administration was done daily for 6 weeks. Results and Discussion: Administration of AECONS or AEGAK increased plasma, hippocampal and hypothalamic glutamate, Na+/K+-ATPase activity, NO, SOD except hippocampal glutamate in AECONS1/AEGAK1, Na+/K+-ATPase activity and SOD in AEGAK1, hypothalamic glutamate and SOD in AECONS1 when compared with control. Besides, MDA level decreased in AEGAK2 and hippocampal but not hypothalamic MDA decreased in AEGAK1 compared with control. However, concomitant administration of AECONS and AEGAK enhanced plasma, hippocampal and hypothalamic biomarkers except hypothalamic MDA level. The present study demonstrates that AECONS and AEGAK synergistically enhances hippocampal and hypothalamic glutamate and Na+/K+-ATPase activity, which are accompanied by NO and SOD-dependent antioxidant enrichment. Conclusion: These findings therefore suggest that AECONS+AEGAK could be a better therapeutic candidate in hippocampal-hypothalamic-related neurodegenerative diseases.
