EVALUATION OF ANTI ULCER ACTIVITY OF THE ETHANOLIC EXTRACT OF PHYLLANTHUS URINARIA IN EXPERIMENTAL ANIMALS

The major population of the world is prone to peptic ulcers, which has become a most prevalent gastrointestinal disorder due to sedentary lifestyle, habituation to junk food, increasing stress, and indiscriminate use of NSAIDS [1]. Peptic ulcer disease occurs due to the alteration of balance between damaging (aggressive) factors such as high acid-pepsin secretion and protective factors (defensive) such as gastromucosal integrity, bicarbonate, and prostaglandin secretion [2]. Helicobacter pylori infection is another major cause of peptic ulcer disease [3]. Many synthetic antiulcer and gastroprotective drugs such as proton- pump inhibitors and H 2 receptor antagonists are available in the market,

Evaluation of anti inflammatory and gastric anti ulcer activity of Phyllanthus niruri L  (Euphorbiaceae) leaves in experimental rats

Evaluation of anti inflammatory and gastric anti ulcer activity of Phyllanthus niruri L (Euphorbiaceae) leaves in experimental rats

The anti-ulcer effect of the methanolic extract was eval- uated using ethanol induced gastric ulcer model. Ethanol induced gastric lesions formed due to interference in gas- tric blood flow which contributes to the development of the hemorrhage and necrotic aspects of tissue injury. Al- cohol swiftly penetrates the gastric mucosa superficially causing cell and plasma membrane damage leading to augmented intracellular membrane permeability to sodium and water. The mammoth buildup of calcium de- scribes a chief step in the pathogenesis of gastric mucosal injury. This sequence leads to the demise of cells and erosion of epithelium’s surface [36, 37].

EVALUATION OF ETHANOLIC EXTRACT OF ROOTS OF TRIANTHEMA TRIQUETRA FOR ANTI-ULCER ACTIVITY IN ALBINO RATS

The aim of the present investigation was to evaluate the antiulcer activity of Trianthema triquetra roots ethanolic extract in Wistar albino rats using NSAIDs & Ethanol induced ulcer models. Plant material was collected from Tirupati A.P, during the month of June 2014. The roots were made free from dust and foreign material and dried under shade at room temperature. After a week the roots were powdered and passed through a sieve. The powder was weighed (500 gm) and was extracted by successive solvent extraction process. The yield of ethanolic extract of trianthema triquetra was found to be 7.31% W/W. Phytochemical screening was carried out for the detection of the phytoconstituents by simple qualitative methods. The dosing was designed as per the acute toxicity study reported earlier. The anti-ulcer activity was performed by NSAID and ethanol induced ulcer model at two different doses, 200mg/kg and 400mg/kg. Wistar rats weighing(130-150gm) of either sex were used for the study. There was significant reduction of ulcers in the test groups observed in both NSAID and ethanol induced ulcer models. TTEE exhibited anti-ulcer activity in both curative and prophylactic experimental models which provides the evidence of its use as a potent anti ulcer drug.

PHYTOCHEMICAL SCREENING AND ANTIOXIDANT ACTIVITY OF AQUEOUS AND ETHANOLIC  EXTRACTS OF TEPHROSIA PURPUREA (L) PERS AND PHYLLANTHUS NIRURI

PHYTOCHEMICAL SCREENING AND ANTIOXIDANT ACTIVITY OF AQUEOUS AND ETHANOLIC EXTRACTS OF TEPHROSIA PURPUREA (L) PERS AND PHYLLANTHUS NIRURI

In recent times much attention has been paid to biologically active plants because of their low production cost and fewer adverse effects compared with allopathic drugs and produce a definite physiological action on the human body. Tephrosia purpurea (L) Pers and Phyllanthus niruri were used as the traditional medicines in India and other parts of world. Both plants were very useful for various pharmacological and biological activities. However, the use of the herbs is not based on any evidence of their contents. In the present study the effects of 2 types of solvents, water and ethanol were investigated to determine the presence of various phytochemical constituent and in vitro antioxidant activities from various parts of Tephrosia purpurea and Phyllanthus niruri. The reason for selecting in vitro method was to minimize the usage of experimental animals. The therapeutic effects of tannins, phenols and flavonoids can be largely recognized to their antioxidant properties. The antioxidant property was determined using DPPH scavenging activity. The study revealed that T. purpurea and P. niruri extract contained proteins, diterpines saponin, phenol, and flavonoid based on phytochemical screening. In DPPH assays ethanolic leave extract of P. niruri possessed highest antioxidant activity with IC50 value of 36.68 μg/ml as compared to other extract. Meanwhile, P. niruri aqueous leave extract showed the activity which was 50.89 μg/ml .Aqueous leave extract of T. purpurea possessed the lowest antioxidant activity 57.49 μg/ml. This study confirmed that P. niruri extract have great potential as a natural antioxidant source as compared to T. purpurea extract.

EVALUATION OF ANTI ANXIETY ACTIVITY OF ETHANOLIC EXTRACT OF Sapindusemarginatus FLOWERS IN EXPERIMENTAL ANIMAL MODELS

EVALUATION OF ANTI ANXIETY ACTIVITY OF ETHANOLIC EXTRACT OF Sapindusemarginatus FLOWERS IN EXPERIMENTAL ANIMAL MODELS

The elevated plus-maze comprised two open (50 cm×10 cm×25 cm) and two enclosed (50 cm×10 cm×40 cm) arms that radiated from a central platform (10 cm×10 cm) to form a plus sign. The maze was constructed of black painted wood. A slight raised edge on the open arms (0.25 cm) provided additional grip for the animals. The plus- maze was elevated to a height of 50 cm above floor level by a single central support. Four 25W red fluorescent lights arranged as a cross at 100 cm above the maze were used as the source of illumination16. The experiment was conducted during the dark phase of the light cycle (9:00–14:00 h). The trial was started by placing an animal on the central platform of the maze facing an open arm. The number of entries into, each of the two types of arm, were counted during a 10 min test period. The percentage open arm entries used as indices of anxiety. A rat was considered to have entered an arm when all four paws were on the arm. The apparatus was cleaned thoroughly between trials with damp and dry towels. All behavioral recordings were carried out with the observer unaware of the treatment the rat had received (Gerhard Vogel et al., 2002).

Evaluation of Antiurolithiatic Activity of Ethanolic Extract of Phyllanthus Urinaria Against Ethylene Glycol Induced Urolithiasis in Wistar Albino Rats

Evaluation of Antiurolithiatic Activity of Ethanolic Extract of Phyllanthus Urinaria Against Ethylene Glycol Induced Urolithiasis in Wistar Albino Rats

Urolithiasis is defined as the presence of one or more calculi in any location within the urinary tract. Urolithiasis is the third most common disorder of the urinary tract, the others being frequently occurring urinary tract infections and benign prostatic hyperplasia. The worldwide incidence of urolithiasis is quite high and in spite of tremendous advances in the field of medicine, there is no truly satisfactory drug for the treatment of renal calculi. Most patients still have to undergo surgery to be rid of this painful disease. Hyperoxaluria is the main initiating factor for urolithiasis. Phyllanthus urinaria is said to be useful in the treating urinary calculi. Hence the present study an effort has been made to establish the scientific validity for the anti- urolithiatic activity.

P eptic ulcer disease is a serious gastrointestinal disorder that requires well targeted therapeutic strategy. A number of drugs including proton pump inhibitors and H2 receptor antagonists are available for the treatment of peptic ulcer, but clinical evaluation of these drugs has shown incidence of relapse, side effects and drug interactions. This has been rational for the development of new anti ulcer drugs and search for novel molecules has been extended to herbal that offer better protection and relapse. The present study is to evaluate the anti ulcer activity by using herbal remedy beta vulgaris. The ethanolic extract of beta vulgaris treated groups shows a significant effect when compared to control group animals which indicating that the plant having the anti ulcer activity. And also the results showed that the ethanolic extract of the beta vulgaris having the antioxidant activity. The acute toxicity study conducted for ethanolic extract of beta vulgaris indicates that safe up to 2000mg/kg body weight. Ulcer can minimize by some life style changes like, avoid eating at least two hours before bed time and whatever foods might cause discomfort, such as alcohol, caffeine beverages (coffee and pop), fatty foods, and highly seasoned foods. It is important to try to stop smoking, since smoking has been linked to ulcer formation, reduced healing, and ulcer recurrences. Also try to minimize stress in life. Stress may worsen ulcer symptoms.

Evaluation of anti-ulcer activity of the leaf extract of <em>Osyris quadripartita</em> Decne. (Santalaceae) in rats

Evaluation of anti-ulcer activity of the leaf extract of <em>Osyris quadripartita</em> Decne. (Santalaceae) in rats

Abstract: Osyris quadripartita (OQ) Salzm. ex Decne. has been used to treat peptic ulcer disease in Ethiopian folk medicine, but its efficacy has not been validated. The present study was therefore carried out to evaluate the anti-ulcer activity of 80% methanol leaf extract of OQ in rats. The effect of OQ extract on gastric ulcer in rats in pylorus ligation-induced and ethanol-induced models was studied using single dosing (100, 200, 400 mg/kg) and repeated dosing (200 mg/kg for 10 and 20 days) approaches. Ranitidine (50 mg/kg) and sucralfate (100 mg/kg) were used as the standard drugs. Depending on the model, outcome measures were volume and pH of gastric fluid, total acidity, ulcer score, percent inhibition of ulcer score, ulcer index as well as percent inhibition of ulcer index. Data were analyzed using one-way analysis of variance followed by Tukey’s post hoc test, and P<0.05 was considered as statis- tically significant. OQ significantly (P<0.001) reduced gastric ulcer index by 55.82% and 62.11%, respectively, in pylorus ligation-induced and ethanol-induced ulcer models at the 400 mg/kg dose, which is comparable to the standard drugs. Ten and 20 days pre-treatment with OQ200 exhibited significant (P<0.001) ulcer inhibition by 66.48% and 68.36% (pylorus ligation-induced model) as well as 71.48% and 85.35% (ethanol-induced model), respectively. OQ possesses both dose-dependent and time-dependent anti-ulcer effect in the two models. The oral median lethal dose (LD 50 ) is estimated to be higher than 2000 mg/kg for the crude hydroalcoholic extract, and secondary metabolites such as flavonoids, tannins, and saponins were present. The findings of this study confirmed that OQ has anti-ulcer pharmacologic activity due to one or more of the secondary metabolites present in it. Therefore, this study validates its anti-ulcer use in Ethiopian folk medicine. Further investigations on isolation of specific phytochemicals and elucidating mechanisms of action are needed.

Evaluation of Analgesic and Anti-inflammatory activity of aqueous extract of Clerodendrum colebrookianum in experimental animals

Evaluation of Analgesic and Anti-inflammatory activity of aqueous extract of Clerodendrum colebrookianum in experimental animals

Thermal stimuli causes pain by stimulation of nociceptive receptors and transmitted over intact neural pathways. Both tail flick and hot plate tests are selectively used to evaluate centrally acting analgesics [14]. The thermal stimulus is also descri- bed as an acute, non-inflammatory nociceptive stimulus as it causes direct stimulation of the nociceptors without causing any inflammatory- mediated nociception. In this present study, mice treated with AECC were more tolerant to the thermal stimulus than those receiving normal saline alone. The analgesic activity was comparable to pentazocine, an opioid analgesic whose analgesic activity is mediated through central route. The analgesic effect of opioids arise from their ability to directly inhibit the ascending transmission of nociceptive information from the spinal cord dorsal horn and to activate pain control circuits that descends from the mid brain via the rostral ventro- medial medulla to the spinal cord dorsal horn [15]. Since, AECC could increase the latency period in mice which was comparable to those mice receiving pentazocine, it may explain the possibility of invol-

STUDY OF THE ANTIDEPRESSANT AND ANTINOCICEPTIVE ACTIVITY OF ETHANOLIC EXTRACT OF RHIZOMES OF ZINGIBER OFFICINALE IN EXPERIMENTAL ANIMALS

STUDY OF THE ANTIDEPRESSANT AND ANTINOCICEPTIVE ACTIVITY OF ETHANOLIC EXTRACT OF RHIZOMES OF ZINGIBER OFFICINALE IN EXPERIMENTAL ANIMALS

Opioids have long been used for treating moderate to severe pain, but treatment with these drugs leads to side effects such as analgesic tolerance, physical dependence, emesis, constipation, and drowsiness. The management of pain remains a major clinical problem. Therefore, it is essential to find new strategies for enhancing the analgesic effects of opioids and natural herbs that have analgesic properties without hazardous side effects. Activation of the opioid receptor inhibits adenylyl cyclase activity via inhibitory G-proteins, closing voltage-activated calcium channels and reducing the Ca influx, thus inhibiting neurotransmitter release and attenuating pain sensation. 6 It has been documented that ginger has Ca channel blocking activity. 7-9

extract and loperamide, 5 mg/kg body weight, loperamide appeared to produce a greater inhibition. This may be attributed to the long duration of action of loperamide. The results obtained showed that the extract of Pn has a great potential to reduce the frequency of stool at a dose comparable to that of the conventional drug used as control. In the presence of castor oil in the gut, prostaglandins are secreted, which in turn induces gastrointestinal motility. 20 Hypermotility is one of the different pathophysiological conditions that characterize diarrhea. The charcoal meal test was carried out to determine the effect of Pn extract on gut motility. Loperamide was used as a control as it has been known to inhibit castor oil-induced diarrhea. 21 As shown in Table 4, it was observed that Pn extract reduced the intestinal transit of charcoal meal by 0.14% and 0.15% by 5 and 200 mg/kg of the extract, respectively, as com- pared to an inhibition of 0.12% by 5 mg/kg loperamide. A reduction in intestinal transit time shows that the extract was able to reduce the motility of the gut and thus reduce diarrhea. Normal saline, which was the negative control,
