PLANT EXTRACTS AND ASPIRIN-INDUCED GASTRITIS: A SYSTEMATIC REVIEW

---

"Gastritis is a disease characterized by the presence of inflammation in gastric
mucosa. Chemical gastritis is a type of gastritis, which occurred due to the prolonged usage
of NSAIDs, including aspirin; bile reflux; or other forms of chemical injury. In 2010, about 43
millions of adults in the United States took aspirin for at least three times per week for more
than 3 months. The consumption of aspirin is also expected to increase in the future,
especially for aging population. Although there are several treatments for aspirin-induced
gastritis, it might not work well for some patients due to poor effectiveness and patient
compliance. Nowadays, plant extract can be considered as an alternative therapy for
digestive system disorder and peptic ulcer disease management. According to WHO,
approximately 65-80% of the current developing countries still utilize medicinal plants as
remedies. However, up until now, there has not been any systematic review about the
efficacy of plant extracts against aspirin-induced gastritis. Therefore, the aim of this review
is to systematically evaluate the pharmacological activities and efficacy of plant extracts
against aspirin-induced gastritis. Out of 337 studies, only 26 studies met the inclusion
criteria. All of the selected 26 studies were conducted in various animal models. The result
showed plant extracts possess numerous pharmacological activities and gastroprotective
mechanisms against aspirin-induced gastritis, such as anti-inflammatory, antioxidant,
antiulcer, gastric acidity reduction, stimulation of gastric mucosal production, and other
pharmacological activities. The anti-inflammatory activity of plant extracts mainly associated
with the reduction of pro-inflammatory cytokines and white blood cells recruitment. The
antioxidant activity related with the increased of gastric antioxidant systems, such as CAT,
GSH, GSH-Px, GST, GR, and SOD, followed by reduction in lipid peroxidation process. Gastric
acidity was reduced via gastric pH elevation, suppression of gastric volume and total acidity.
Stimulation of gastric mucosal production was induced by higher PGE2 level and mucosal
cells proliferation. Other pharmacological activities mainly correlated with NO levels to
maintain gastric blood flow conditions and lowered peptic activity to prevent gastric cells
death. Additionally, several plant extracts managed to established considerable
pharmacological activity toward aspirin-induced gastritis. T. pentranda and A. manihot
extracts decreased ulcer index (UI) up to 0, while A. marmelos extract increased gastric
mucosal thickness up to 602.45±0.04 μm. Moreover, V. amygdalina leaves extract
v
demonstrate the greatest efficacy in terms of gastric pH value elevation up to 5.27±0.18,
yet able to maintain architecture of healthy stomach tissues in contrast with other plant
extracts. Interestingly, M. oleifera aqueous extract and O. basilicum hexane extracts have a
very broad pharmacological activity based on the results. Nevertheless, further studies are
required to confirm whether the other plant extracts elicit these pharmacological activities
and gastroprotective mechanisms against aspirin-induced gastritis."
