review of medicinal plants exhibiting potential anti-ulcer activity

Plants have been used for medicinal purposes from the time immemorial. Medicinal plants are an indispensable source of new chemical substances with potential therapeutic effects. Their chemical compounds may serve as lead for the development of new drugs. In the present communication a review of the plants exhibiting antiulcer activity is presented

Antimicrobial activity of parmelia perlata

Petroleum ether, chloroform and alcoholic extracts of lichen Parmelia perlata showed inhibitory activity against both gram positive and gram negative bacteria namely Streptococcus aureus and Escherichia coli, respectively and fungus Malassezia furfur

In vitro Inhibition Effect of Plant Extracts, Urine, Fertilizers and Fungicides on Stem Rot Pathogen of Sclerotium rolfsii

Twenty plant extracts were tested against mycelial growth, sclerotium formatiom and dry weight of mycelium with sclerotia of Sclerotium rolfsii Sacc. The highest(90 mm) mycelial growth was measured in Adhatoda vasica, Tegetes erecta, Allium cepa, and Curcuma longa. The lowest(25 mm) was in Azadirachta indica. No mycelial growth was found in any concentration of cow, buffalo, and goat urine. The highest(90 mm) and the lowest(15 mm) mycelial growth were measured in Biomil and Urea, respectively. No mycelial growth was observed in Zinc. The highest(60 mm) and the lowest(2 mm) mycelial growth were recorded in Macuprex(Dodine; 65% WP) and Boron(100% Boric acid and 17% Boron) respectively. Mycelial growth was totally inhibited in Rovral(Iprodione; 50% WP).

In Vitro Effect of Fungicides, Plant Extracts and Smoke on Conidial Germination of Fusarium oxysporum Root Rot Pathogen of Piper betle

Five fungicides such as rovral, bavistin, cupravit, dithane M-45 and thiovit were tested against conidial germination of Fusarium oxysporum. Dithane M-45 was the most effective against the fungus. Rests of the fungicides were more or less effective in the inhibition of conidial germination after 5~30 minutes immersion in 500~2500 ppm concentration. Five plant extracts(leaf extracts of Ocimum sanctum, Lantana camera, Calotropis procera, Azadirachta indica and Vinca rosea) found to be more or less effective against the fungus. 'Dhup' somke have good inhibitory effect on conidial germination of F. oxysporum.

Effects of Plant Extracts on Conidial Germination, Mycelial Growth and Sporulation of Fungi Isolated From Poultry Feed

Effect of ethanolic extracts of Lawsonia inermis, Azadirachta indica, Vinca rosea, Tagetes patula, Ocimum sanctum, Colocasia antiquorum, Adhatoda vasica, Moringa oleifera, Datura metel and Curcuma longa leaf on conidial germination, mycelial growth and sporulation of Aspergillus flavus, A. niger and A. fumigatus were examined. The conidial germination of A. flavus and A. fumigatus were most inhibited by the extract of L. inermis, while that of A. niger was inhibited by A. indica. Other tested plant extracts have a good effect on conidial germination on the selected fungi. The highest mycelial growth of A. flavus (37 mm) was found in V. rosea, but in case of A. niger and A. fumigatus it (38 and 39 mm) was found in D. metel. The lowest (4, 9 and 6 mm) respectively mycelial growth of these fungi found in L. inermis. The highest sporulation (75 x 10(4)/ml) of A. flavus was counted in V. rosea, but in case of A. niger and A. fumigatus those (45 x 10(4) and 55 x 10(4)/ml) were in D. metel and the lowest (5 x 10(4), 12 x 10(4) and 9 x 10(4)/ml) respectively sporulation of these fungi counted in L. inermis plant extract medium.

Mesenteric vasculitis A diagnostic dilemma

Mesenteric vasculitis is a rare diagnosis. Although it has been described more than a century ago, clinicians still face difficulties in making an early diagnosis. We report a case who presented with symptoms of severe rheumatoid arthritis [RA] and abdominal pain and subsequently twice developed intestinal perforation within a period of one week. Laparotomy on both occasions disclosed multiple subserosal small bowel ulcers, histopathology of which was reported as polyarteritis nodosa. While early surgical intervention might be life saving in a localised small bowel vasculitis, its efficacy in progressive involvement of multiple segments is doubtful
