A review on antiulcer activity of few Indian medicinal plants.

Ulcer is a common gastrointestinal disorder which is seen among many people. It is basically an inflamed break in the skin or the mucus membrane lining the alimentary tract. Ulceration occurs when there is a disturbance of the normal equilibrium caused by either enhanced aggression or diminished mucosal resistance. It may be due to the regular usage of drugs, irregular food habits, stress, and so forth. Peptic ulcers are a broad term that includes ulcers of digestive tract in the stomach or the duodenum. The formation of peptic ulcers depends on the presence of acid and peptic activity in gastric juice plus a breakdown in mucosal defenses. A number of synthetic drugs are available to treat ulcers. But these drugs are expensive and are likely to produce more side effects when compared to herbal medicines. The literature revealed that many medicinal plants and polyherbal formulations are used for the treatment of ulcer by various ayurvedic doctors and traditional medicinal practitioners. The ideal aims of treatment of peptic ulcer disease are to relieve pain, heal the ulcer, and delay ulcer recurrence. In this review attempts have been made to know about some medicinal plants which may be used in ayurvedic as well as modern science for the treatment or prevention of peptic ulcer.

Assessment of Discomfort Experienced by School Children While Performing 'ART' and 'MCP'-An Experimental Study.

OBJECTIVE: Atraumatic Restorative Treatment (ART) is a minimal intervention technique in the management of carious lesions, which results in negligible discomfort to the patient. The aim of this study was to assess and compare the discomfort levels during Atraumatic Restorative Treatment and Minimal Cavity Preparation (MCP: a method using rotary instruments) treatment procedures in a sample of school children in Davangere city. MATERIALS AND METHODS: An experimental study was performed aimed at comparing discomfort levels as measured by subjective (Venham index) and objective (Heart rate) methods at six specified moments during the treatment. A total of 200 children were randomly divided into two groups of 100 each. In each child, one class II restoration with GIC in a deciduous molar was performed. One group received treatment using rotary instruments (MCP) and the other group with ART. Discomfort levels were measured using Venham index (behavioural dimension) and heart rate (physiological dimension). RESULTS: The behavioural measurement revealed that in ART group the majority of the children(64%) showed an overall Venham score of '<1'(relaxed) as compared to MCP group in which the majority of children (76%) showed a Venham score of '1'(uneasy). The physiological measurement revealed that the children in ART group experienced less discomfort when compared to children in MCP group. CONCLUSION: The results of the study suggest that ART induces less discomfort; is patient friendly and has a higher extent of community acceptance when compared to MCP.

Study of antidiarrhoeal activity of four medicinal plants in castor-oil induced diarrhoea.

A study was undertaken to evaluate the effect of aqueous and methanolic plant extracts of Acorus calamus rhizome, Pongamia glabra leaves, Aegle marmelos unripe fruit and Strychnos nux-vomica root bark for their antidiarrhoeal potential against castor-oil induced diarrhoea in mice. The methanolic plant extracts were more effective than aqueous plant extracts against castor-oil induced diarrhoea. The methanolic plant extracts significantly reduced induction time of diarrhoea and total weight of the faeces. The result obtained establish the efficacy of these plant extracts as antidiarrhoeal agents.
