The study showed that the three extracts at the concentrations used against the two test organisms, Staphylococcus aureus OOUTH206 (0.5mg/ml for Garcinia kola, 4mg/ml for Kola acuminata and Kola nitida) and Pseudomonas aeruginosa UCH189 (8mg/ml for Garcinia kola, 15mg/ml for Kola acuminata and Kola nitida); had activity on the two microorganisms. There was a gradual reduction in the number of viable microbial counts as evident in the reduction in the cell number at the different time intervals. Similar procedure was carried out in the presence of 5% serum protein and it was observed that the activities of the various extracts were altered significantly indicating the effect of serum protein binding on the constituents of Garcinia kola, Kola acuminata and Kola nitida seed extracts. The results were expressed in percentage viable count of the inoculum size and showed that the percentage viable count decreases with time in varying degrees. The reduction was more intense with G. kola extract than the other extracts on S. aureus as well as on P. aeruginosa towards the third and fourth hours. The effect of serum protein was seen to affect the activities of all the extracts in varying degrees as shown in the graphs plotted.

Different doses of plant extract were administered at once orally to 8groups of 10 each. The mortality rate was evaluated after 48 hours. The macroscopic, biochemical and histological modifications were determined seven days later. The optimal tolerated dose was 9 g/kg. The mean lethal dose (LD50) and the total lethal dose (LD100) were respectively 14.10 g/kg and 18 g/kg with a mortality rate of 42 %. The aqueous doses of Celtis duranndii extract of 3 15 g/kg provoked a significant and dose-dependent decrease in the serum protein levels from 6.79 % to 63.04 %. Creatinine, cholesterol and liver proteins increased. Histological analysis conducted for higher dose of plant extract (15-18 g/kg) revealed a vascular congestion, a necrosis of hepatocytes, and an overcharge of lipid (steatose). The extract caused increase in both ALT and AST serum levels with that of AST higher as reflected in number of organs capable of releasing it. The increase in transaminases might in part be due to its chemical (steroid) constituent, since steroids are known to interfere with the integrity of liver and kidney. The histology of kidneys indicated blood vessel congestion, a slight glomerulosclerosis and accumulation of intratubular fibres occupying the light of tubules. The lethal concentration (LD50) was 3 times higher than 5 g/kg, thus C. durandii relatively seems to be less toxic and possesses an important therapeutic activity.
