East coast of Surabaya is wetlands area in Surabaya that most of the region have change into fi shpond and residental. The aims of this reasearch are to determine the community structure of waterbirds in each type of wetland utilization and to determine if the different type of wetland utilization infl uence the community structure of waterbirds in East Coast of Surabaya. Data were collected during August 2012 to January 2013 with point count method. Six sampling plots have been selected. Six sampling plots representing four types of use of wetlands, which are bozem, the former fi shpond, fi shpond with vegetation, and fi shponds without vegetation (fi shpond 1, fi shpond 2 and fi shpond 3). In bozem recorded 19 species of waterbirds (1107 individual), dominated by shorebirds, with a diversity index (H') 1.86, and evenness index (J') 0.63. In former fi shpond recorded 7 species of water birds (168 individual), dominated by rails and moorhen, with H’ = 1.12 and J’ = 0.57. In fi shpond with vegetation recorded 12 species of water birds (137 individual), dominated by large wader, with H’ = 1.85 and J’ = 0.74. In fi shpond 1 recorded 18 species of water birds (299 individual), dominated by terns, with H’ = 1.96 and J’ = 0.68. In fi shpond 2 recorded 9 species of water birds (70 individual), dominated by terns, with H’ = 1.73 and J’ = 0.79. In fi shpond 3 recorded 10 species of water birds (83 individual), dominated by terns, with H’ = 1.84 and J’ = 0.80. Chi-square test showed that X2 count is greater than X2 table with α < 0.05, which indicates that there is a signifi cant difference of the number of individuals of each species and the number of individual of each water birds’ group for each type of use of wetlands, so it can be concluded that different types of use of wetlands affect water bird community structure in the East Coast Surabaya.","PeriodicalId":31368,"journal":{"name":"Journal of Biological Researches","volume":"11 10 1","pages":"25-30"},"PeriodicalIF":0.0,"publicationDate":"2012-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82734961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vahl) contain many fl avonoids compound. It is a potential candidate to supress the infl ammatory process through down regulation of TNF-α level as a potent pro-infl ammatory cytokine in chronic infl ammation cases. The aim of this research was to improve the effect of Porterweed leaf extract to the TNF-α level and considered the optimum dosage in wistar rats with chronic infl ammation model. Twenty fi ve rats was divided into negative control group, positive control group, and treatment groups with dosage 50, 100 and 150 mg/kg BW. Data obtained through microscopical histologic observation on aortic organ after immunohistochemistry staining and was analyzed descriptively. The result revealed that Porterweed leaf extract is able to inhibit the increasing of TNF-α level. This phytochemical substance is predicted capable of preventing the oxidation reaction progession of cyclooxygenase-2 (COX-2) to produce prostaglandins. The decreasing of prostaglandin level causes a negative feedback to TNF-α production and iniciating the declining level of TNF-α. Thus, the Porterweed leaf extract indicates supress chronic infl ammatory process through down regulation of TNF-α and prostaglandin activity in optimum dose 150 mg/kg bw.","PeriodicalId":31368,"journal":{"name":"Journal of Biological Researches","volume":"23 1","pages":"57-60"},"PeriodicalIF":0.0,"publicationDate":"2012-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82273211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
