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.

Abstract Background Several local communities in Central, Western, Eastern, and Northern regions of Uganda have been using the whole leaf extracts of Aloe vera (L.) Burm. f. (Asphodelaceae) in the treatment of various ailments. Also, several commercial companies sell A. vera as soft drinks in Uganda. However, there are inadequate reports on the toxicities of such preparations. This paper reports the acute and sub-acute oral toxicity of aqueous extracts of whole leaf and green rind of A. vera in Wistar rats. Methods Acute oral toxicity test was carried out in female Wistar rats at doses of 175, 550, 1750, and 5000 mg/kg, p.o. The animals were observed for signs of toxicity for 14 days. Similarly, a sub-acute oral toxicity test was performed in both sexes of rats at doses of 200, 400, and 800 mg/kg, p.o. daily for 28 days. All the groups of animals were monitored for behavioral, morphological, biochemical, and physiological changes, including mortality and compared with respective controls. Body weights were measured weekly while the animals’ relative organ weights, hematological, biochemical, gross, and microscopic pathology were examined on day 29. Results There was no mortality or apparent behavioral changes at the doses tested in acute and sub-acute oral toxicity tests. Thus, the Median Lethal Dose (LD50) of green rind and whole leaf aqueous extracts was above 5000 mg/kg. Gross anatomy revealed that the rats’ relative spleen weight in green rind extract at 200 mg/kg significantly decreased compared to the control group. The creatinine levels in female rats that received green rind extract and the chloride ion levels in male rats administered whole leaf extract were significantly elevated. Conversely, Mean Corpuscular Hemoglobin Concentration (MCHC) levels significantly decreased at lower doses of the green rind extract compared to the control. Histopathology of the kidney revealed the renal interstitium’s inflammation at doses of 200 and 800 mg/kg of the whole leaf extract. Conclusion The findings demonstrated that A. vera green rind and whole leaf extracts are non-toxic at relatively high doses when used for a short duration. Prolonged use of the aqueous whole leaf extract might be associated with kidney toxicity.

Diabetes mellitus is prevalent in many countries of the world, affecting all ages both in developing and developed nations. The use of plants as remedies or preventive therapies has increased over the years. The study investigated the biochemical changes caused by  combined leaf extracts of Vernonia amygdalina (bitter leaf) and Gnetum africanum (okazi leaf) on alloxan induced diabetic wistar rats.Aqueous extracts of the leaves were prepared using the conventional method.Forty male wistar rats weighing 150-180g were  grouped into eight (five rats each). Group 1 was the normal control while diabetes was induced using alloxan (160mg/ kg)in groups 2-8.Group 2 received no treatment while groups 3-7 received varied ratios of the extracts at (BI/OK|10:90%), (BI/OK|30:70%),  (BI/OK|50:50%), (BI/OK|70:30%) and (BI/OK|90:10%). Group 8 was the diabetic control treated with the standard diabetic drug (Metformin). The animals were weighed and blood glucose was determined at 7-day intervals. They were sacrificed on the 28th day and blood samples collected for serum protein, serum electrolyte, urea, creatinine, liver enzymes and markers of oxidative stress analyses.  The results showed steady increase in the body weights (g) of the rats with (BI/OK|70:30)% treated group showing the highest increase (175.40±1.28). The fasting blood sugar (mg/dl) showed timedependent reduction in all the treated diabeti groups with (BI/OK|90:10)% having the highest (56.20±1.65) reduction. There was a significant increase (p<0.05) in total blood protein concentration (g/dl) in all the treated groups. The results of this study showed time and ratio dependent effect on the parameters measured. Since the two plants are staple vegetables in some countries, their utilization particularly in appropriate combinations should be encouraged. Key words: Extracts, bitter leaf, waterleaf, diabetes mellitus, biochemical parameters.

Terminalia tomentosa bark belongs to the family Combretaceae. The plant bark is astringent and useful in the treatment of ulcers, vata, fractures, hemorrhages, bronchitis, and diarrhea. Phytochemical investigation of T. tomentosa bark confirms the presence of flavonoids, polyphenols, and tannins. The plant has not been investigated for its anti-inflammatory and antiarthritic activity. The present study was undertaken to explore its possible anti-inflammatory and antiarthritic activity. Anti-inflammatory activity of alcoholic and aqueous extracts of the bark was assessed by in vivo methods. In vivo antiarthritic potential of the extracts was evaluated by Complete Freund’s Adjuvant (CFA) induced arthritis in Wistar rats. Our findings showed that the alcoholic and aqueous extracts exhibited anti-inflammatory activity at 500 mg/kg oral dose in carrageenan-induced hind paw edema and carrageenan-induced air pouch inflammation models. We also found alcoholic as well as aqueous extracts of the bark restored the altered blood and serum parameters caused by the Complete Freund’s Adjuvant-induced arthritis in Wistar rats. This study shows that the T. tomentosa bark extracts possess anti-inflammatory activity and have pronounced effects on adjuvant arthritis also. Future studies are necessary to provide deeper insight into the exact mechanism of the action of anti-inflammatory and antiarthritic activity of T. tomentosa.
