Objective: Phaseolus vulgaris, like other beans, is endowed with rich nutritional contents. This study evaluated the effects of raw and cooked aqueous and methanol extracts of P. vulgaris on renal function in albino Wistar rats.
Methods: Oral acute toxicity (LD50) study of both extracts was conducted in two phases. In the main design, a total 36 Wistar albino rats were used and divided into nine groups of four rats and oral administration lasted for 7 days. Group 1 served as control and 2 – 9 treated groups. Groups 2 and 3; 4 and 5 were administered aqueous extracts while groups 6 and 7; 8 and 9 were administered methanol extracts of 350mg/kg and 550mg/kg body weight raw and cooked P. vulgaris respectively.
Results: Results of LD50 of all extracts were greater than 5000mg/kg. Results showed a significant (P<0.05) increase in concentrations of urea and chloride across test groups administered aqueous extracts, than methanol extracts; a significant (P<0.05) increase in serum creatinine in test groups administered methanol extracts; a significant (P<0.05) increase of serum total protein of test groups compared to control; no significant (P<0.05) difference in the concentration of potassium in test groups administered compared to control group.
Conclusion: It may be concluded that P. vulgaris portrays potentials capable of improving renal function and its consumption may contribute to the wellness of a person due to its rich nutrients, and based on the duration of this work and standard scale of toxicity; the extracts are practically non- toxic since the LD50 was greater than 5000mg/kg.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
