EVALUATION OF ANTI-DEPRESSANT ACTIVITY OF ETHANOLIC ROOT EXTRACT OF ANNONA SQUAMOSA L

EVALUATION OF ANTI-DEPRESSANT ACTIVITY OF ETHANOLIC ROOT EXTRACT OF ANNONA SQUAMOSA L

This work has been done for the investigation of the anti-depressant activity of Ethanolic root extract of Annona squamosa (EREAS) belongs to the family Annonaceae by oral administration at dose according to the body weight in a sequential manner in healthy albino rats. Extracts were studied for its anti-depressant activity by using Imipramine as standard drug. Forced swim test (FST) and Tail suspension tests (TST) are used for the study. Imipramine decreases the immobility time of the animals. Plant extract given in three doses (100, 200 and 300mg/kg) were in a dose dependent manner. 300mg/kg plant extract showed decreased immobility time near as to that of the standard drug. The decrease in immobility period in both the models was observed starting from 200 mg/kg. But the increase in dose from 200 to 300 mg/kg produces further reduction in immobility period. At the dose 100 & 200mg/kg, ASRE showed a little antidepressant effect when comparable to that of Imipramine. At the dose 300 mg/kg, ASRE showed antidepressant effect which is comparable to that of Imipramine. This evaluation may suggest that the antidepressant action is because of the possible involvement of either nor-adrenergic or serotonergic system.

Effects of ethanolic extract of Annona squamosa L  leaves on the expression of EGFR

Effects of ethanolic extract of Annona squamosa L leaves on the expression of EGFR

The precise causes of psoriasis, a relatively common, chronic, inflammatory and hyperproliferative skin disease, are still not known, thus making it very difficult for treatment. We previously found an in vitro anti-psoriatic activity in ethanolic extract of Annona squamosa L. leaves. Epidermal growth factor receptor (EGFR) and its ligand, transforming growth factor (TGF)-α, have been demonstrated to be strikingly upregulated in active psoriatic plaques, thus implicating their functional roles in psoriatic hyperplasia. The objective of this study was to investigate the molecular effect of ethanolic extract derived from Annona squamosa L. leaves on the EGFR expression using HaCaT keratinocyte cell line as a model. Based on RT-PCR, concentrations at 3.15 and 1.575 µg/mL (IC 50 = 6.3 µg/mL) significantly reduced the EGFR mRNA expression (P<0.05) as compared to control

Anti ulcer activity of methanolic extract of Hibiscus cannabinus (Leaves) in wistar strain rats

Anti ulcer activity of methanolic extract of Hibiscus cannabinus (Leaves) in wistar strain rats

In indomethacin induced model, the control animals produced characteristic lesions in the glandular portion of rat stomach which appeared as elongated bands of thick, black & dark red lesions. Methanolic extract of Hibiscus cannabinus treated animals showed significant protection index of 54% and 66% with the dose of 1.6and 3.2g/kg respectively in comparison to control (Results are tabulated in Table-II). In indomethacin induced model, ulcers are caused due to inhibition of synthesis of endogenous cytoprotective Prostaglandin(PG). The excess gastric acid formation by prostaglandin includes both increase in mucosal resistance as well as decrease in aggressive factors, mainly acid and pepsin. Inhibition of PG synthesis by indomethacin coincides with the earlier stages of damage to the cell membrane of mucosal, parietal and endothelial cells. Indomethacin induced gastric lesion formation may be due to stasis in gastric blood flow because of vascular congestion and mucosal capillary necrosis and this contributes to the development of the hemorrhage and necrotic aspects of tissue injury[17]. Indomethacin directly acts on gastric epithelium and produces lipid peroxidation. The extract shows protection against characteristic lesions produced by indomethacin and also showed significant decrease in ulcer index. The cytoprotection offered here might be due to significant antisecretory property of the extract and could have inhibited indomethacin induced inhibition of PG synthesis. The preliminary phytochemical studies revealed the presence of flavanoids; various flavanoids have been reported for its anti-ulcerogenic activity. So the possible mechanism of anti-ulcer activity might be due its flavanoid content[18,19]. Further studies are needed for their exact mechanism of action on gastric acid secretion and gastric cytoprotection.

formation, reduce gastric acid secretion and inhibit pepsinogen production thereby reduced gastric lesions and ulcers. Flavonoids are among the cytoprotective materials for which antiulcerogenic efficacy has been extensively confirmed (Di Carlo et al., 1999; Borrelli et al., 2001; Galati et al., 2001). It is suggested that, these active compounds would be able to stimulate mucus, bicarbonate and the Prostaglandin secretion and counteract with the deteriorating effects of reactive oxidants in gastrointestinal lumen (Salvayre et al., 1982; Asuzu and Onu, 1990; Suja et al., 2002). Other components like alkaloids, saponins, and tannins are also present in the leaf extract of D. guineense which tend to exhibit some anti inflammatory and anti-oxidant properties (Ghosal et al., 1996; Nwaogu et al., 2007). It is obvious that the decrease in gastric ulceration, with concomitant in the gastric mucus secretion produced by the leaf extract of D. guineense in this study could be due to the presence of these components or some other mechanisms yet unidentified. This indicates that D. guineense can be subjected to further studies in order to isolate the active ingredients in the leaves as well as determine the mechanism of action of such active ingredients. These may ultimately yield better anti-ulcer agents than we have in the market today. In conclusion, the present study have established the anti-ulcer effects of aqueous extract of D. guineense leaves and further justifies the folkloric uses of the decoction of the leaves for the treatment of gastric ulcer.

EVALUATION OF ANTI ULCER AND ANALGESIC ACTIVITY OF METHANOLIC EXTRACT OF LEAVES OF ANNONA RETICULATA LINN

EVALUATION OF ANTI ULCER AND ANALGESIC ACTIVITY OF METHANOLIC EXTRACT OF LEAVES OF ANNONA RETICULATA LINN

Peptic ulcer is the most common gastrointestinary disorder in clinical practice. [1] It is a defect in the lining of the stomach or the first part of the small intestine (duodenum). It becomes one of the must public health problem with high rate of morbidity and substantial mortality and has become the focus of experimental and clinical investigations, mainly due to its high prevalence in the global population. [2] Every year peptic ulcer affects nearly four million people worldwide and affects 10% of world population with different aetiologies. [3, 4] Ulcers are an open sore of the skin or mucus membrane characterized by sloughing of inflamed dead tissue. A gastric ulcer can give epigastric pain during the meal, as gastric acid production is increased after the meal and food enters the stomach. Symptoms of duodenal ulcers would initially be relieved by a meal, as the pyloric sphincter closes to concentrate the stomach contents; therefore acid is not reaching the duodenum. [5]

INFLUENCE OF AQUEOUS EXTRACT OF ANNONA SENEGALENSIS LEAVES ON SOME PARAMETERS OF INFLAMMATION ON RAT SPECIALLY THOSE OF ‘WISTAR’ ORIGIN

This study showed an anti-inflammatory effect of the aqueous extract of leaves of Annona senegalensis on the model of carrageenan inflammatory edema in rats and a significant decrease in CRP. This activity is greater at the dose of 750 mg / kg body weight and is thought to be related to the inhibition of cyclooxygenases and lipoxygenases in the late phase of carrageenan inflammatory edema and these different secondary metabolites. The evaluation of the anti-inflammatory activity of the extract establishes the scientific basis for the use of Annona senegalensis leaves to prevent and treat various inflammatory diseases. Studies should also focus on the purification of the active ingredients responsible for the effects of this plant and on the determination of the molecular mechanisms involved for the preparation of improved forms of effective remedies based on Annona senegalensis.
