I n vivo activity was studied on chronic gastric ulcers induced by injection of 0.05 ml of acetic acid (30%) into the stomach wall. Rats were treated daily for 10 days after ulcer induction with a combination of E. speciosa and MY41g (ESMY) ; (ESMY 100+250 and 200+250 mg/kg). The model of \"unhealed\" gastric ulcers was also used: from day 5 to day 18 of experimentation, rats were given ESMY orally concomitantly with indomethacin (1 mg/kg/day) subcutaneously. Ulcer index, percentage of healing, mucus secretion, gastric acidity, histological, hematological, and oxidative stress parameters were evaluated. Results: ESMY showed good neutralizing capacity in vitro in Fordtran’s method. Treatment with ESMY accelerated the spontaneous healing of chronic gastric ulcers (93.82-96.14%). However, administration of indomethacin did not induce significant variations in the percentage of healing (90.73-94.60%). For both ulcer models performed, ulcer healing was accompanied by a significant ( P = 0.001) increase in mucus mass at 200/250 mg/kg.

Study Design: The interactive plots serve to show the effect of one variable (lead) on the value of mercury (the other) and is derived by selecting high and low values for lead (Pb) and entering them into the equation along with the range of values for Mercury (Hg). The values of independent Original Research Article Aroh and Udensi; JABB, 24(2): 34-42, 2021; Article no.JABB.67623 35 variables (lead and mercury levels) used in the plots were selected by observing the highest concentration (+1) and lowest concentration (-1) values which are able to support nitrogen fixation independently in Rhizobium and Xanthobacter.

From these samples, both Rhizobium and Xanthobacter spp were isolated. The isolated organisms were re-vitalized in Jensen’s nitrogen free broth and standardized to 0.5 McFarland standards. To determine nitrogen fixation, the broth cultures were examined for nitrate nitrogen (NO3-N) and amino nitrogen (Amino-N) levels after ten days of the experiment under continuous airflow using the Jensen’s nitrogen free broth containing the metal salts, Mercury (II) chloride HgCl2 and Lead (II) acetate trihydrate Pb (CH3COO)2.3H2O).

The strain L. plantarum 29V was added in pasteurized honey and was studied its viability in honey and its impact on the physicochemical parameters of honey.
