In-vivo antiulcer activity
This study aimed to evaluate the protective potential of ethyl acetate
extract and isolated pure compounds against stomach ulcers caused by
pylorus-ligation and ethanol-induced ulcers. The researchers induced
gastric ulceration in animals by administering ethanol (1 mL/200 g b.
w.) orally and by pylorus ligation using pentobarbitone (35 mg/kg i.p.).
2.7.1. Ethanol-induced ulcer
Disease control (ethanol), positive control (ranitidine) and, test
samples {ZA/Ea, ethylacetate extract (250 mg/kg); ZA/Eb, ethylacetate
extract (500 mg/kg); ZA/1a, tambulin (25 mg/kg); ZA/1b, tambulin (50
mg/kg); ZA/2a, ombuin (25 mg/kg); ZA/2b, ombuin (50 mg/kg)} were
given to the rats twice a day orally for 5 days prior to ulcer induction.
According to the method described by Hollander et al., 1985, rats were
administered with ethanol orally on 6th day (1 mL/200 g, 1 h) to induce
uniform gastric ulcers and ranitidine was given as positive control at the
dose of 50 mg/kg, orally. After the rats were euthanized, their stomachs
were examined along the greater curve to assess the presence of ulcers.
To determine the ulcer index, the length and width of ulcers in the
glandular part of the stomach were multiplied (mm
2
/rat). This method
provides a reliable and efficient way of analysing the effects of ethanol
on the development of gastric ulcers in rats. Ulcer index protection was
determined by the following formula:

tambulin, (25 mg/kg); ZA/1b, tambulin (50 mg/kg); ZA/2a, ombuin
(25 mg/kg); ZA/2b, ombuin (50 mg/kg)} were given to the rats for 5
days, and then they were kept in a cage for 18 h without food. Pento
barbitone (35 mg/kg, i.p.) was used for sedation of animals. The belly
was then opened and the pylorus was tied off without hurting the ani
mals’ blood supply. It was carefully brought back in place, and the wall
of the belly was closed in two layers with stitches that were broken so
often. After the surgery, the animals were not given any water (Shay
et al., 1945). After 4 h, the animals were sacrificed, and the stomach was
carefully taken out and cut along the larger curve. It was then carefully
washed with 5.0 mL of 0.9 % NaCl, and ulcers were scored in the
glandular part of the stomach by someone who wasn’t part of the
experiment. The ulcer index was estimated by adding the number of
ulcers on each stomach and how bad each ulcer was. The method given
by Sanyal et al. (1982) was used to figure out the ulcer score for the
whole group.
2.8. Measurement of inflammatory cytokines
2.8.1. IL-1β, TNF-α, and IL-6
Were measured using an ELISA kit within 2 hrs, and the concentra
tion was calculated by following the standard procedure. Leukocyte
infiltration was observed in the deep mucosal layer. A homogenate was
prepared from the detached scarred fraction. The supernatant collected
from the homogenate was used for further studies of interleukins
(Almasaudi et al., 2016).
2.9. Histopathology
Histopathology was examined by rats’ stomach which were fixed in
10 % neutral formalin, then embedded in paraffin blocks. The eosin and
hematoxylin stains were used for the section visibility. The degree of
stomach damage was determined using the standard procedure
mentioned in MICRON desquamative changes, mucosal defects of
varying depths, and the degree of infiltrative changes.
2.10. Gastric wall mucus measurement
Corne et al. (1974) developed a method for measuring gastric wall
mucus in ethanol-induced ulcerated mice. Glandular segments from
stomachs were isolated, weighed, and then incubated for 2 h in a 1 %
Alcian blue solution (0.16 M sucrose in 0.05 M sodium acetate, pH 5.8)
in test tubes. After centrifuging (100 g) the Alcian blue binding extract
for 10 min, the absorbency of the supernatant was determined at 498
nm. The amount of Alcian blue taken from the glandular tissue was then
determined (µg/g of glandular tissue).
2.11. Statistical analysis
The obtained data were processed to determine the significant dif
ference between the groups. Standard mean and error were optimized.
To summarise the results, a one-way analysis of variance (ANOVA) was
employed. Version 5.01 of GraphPad PRISM (GraphPad Software, Inc.,
USA) was used. The value p <0.05 was regarded as a significant
indication.
