Abstract

ABSTRACTBitter (Andrographis paniculata Nees.) widely used for the treatment of various diseases, such as influenza, HIV anti-cancer and anti-inflammatory, antifertility. The main content of the bitter is Andrographolide. Andrographolide is the activeantimitotic bitter agentthat prevents cell division (cytokinesis) and reduced sperm count. This study aimed to determine the effect of extract of bitter (Andrographis paniculata Nees.) on the quality of epididymal spermatozoa of mice (Mus musculus L.) Swiss Webster.This research was conducted usingCompletely Randomized Design (CRD) consisting of 4 treatments and 6 replications. Firs (I) treatment was the control, without any bitter extract. Treatments II, III, and IV is the provision of a bitter extract orally for 36 days with a dose of 0.2 g /mice/day, 0.4 g/mice/day or 0.6 g/mice/day. After treatment, the animals were decapitated, dissected and taken epididymal, and then put into the cup petridis already containing PBS solution. Calculation of number of normal and abnormal spermatozoa number were conducted using Improved Neubauer. Data were analyzed by ANOVA (Analysis Of Varian) that epididymal sperm normal and abnormal.The results shoured by the average sperm count is highest in the control of 29.83 x 105, whereas at a dose of 0.2 g of as much as 18.17 x 105, 0.4 g of as much as 24.33 x 105 and 0.6 g as much as 14.17 x 105. Delays due to the reduced number of sperm in the seminiferous tubules of the process of mitosis by antimitotic compounds. While granting that the higher the extract resulted in increased number of abnormal sperm. The causes of abnormal sperm maturation of spermatozoa due to disruption in spermiogenesis phase. The fewer the number of normal sperm treated with increasing doses. It can  concluded that the extract of bitter given orally for 36 days can decrease sperm quality mice and increases sperm abnormalities.

Abstract

ABSTRACT Soil is one of important factors directly affecting growth and development of mangrove forest. The relationship between mangrove and soil is complemented by the ability of different types of mangrove to grow in different substrates. Rhizopora apiculatais distributed in all textures of soil (loam, sandy loam, clay loam, sandy clay loam, clay and loam sandy). Sonneratia caseolarisis distributed in loam, sandy loam, clay loam, sandy clay loam and clay. Aegiceras corniculatumis distributed in loam, sandy loam, sandy clay loam and loam sandy. Dolichandrone spathacea is distributed in loam, sandy loam, clay loam, and sandy clay loam. Bruguiera gymnhorrizaand Hibiscus tiliaceus are distributed in loam,sandy loam, and sandy clay loamwhile Acanthus ilicifolius is distributed in loam and sandy clay loam. This study aims to comprehend the relation between the distribution of the plant with the texture of soil in the mangrove forest of  teluk  buo in the subdistrict of bungus teluk kabung in the city of padang. This deskriptive work was performed form June to July, 2013. Samples were colected from a 10 m by 10 m study plot placed along transection line from the star of shoreline until the border between mangrove and land forest. At the study location  transections were created with the lenght of 160 m (transection 1) and 180 m (transection 2). With the distance between recorded for each plot, knows plants were recorded on the spot while the unknows were collected at mangrove forest of the teluk buo and soil textures were determined at the laboratories. The study found that there are six types of soil textures in the area consisted of loam,sandy loam, clay loam, sandy clay loam, clay and loam sandy. Distributed plants were identified as Rhizophora apiculata, Sonneratia caseolaris, Aegiceras corniculatum. Bruguiera gymnhorriza, Dolichandone spathacea, Acanthus ilicifolius, and Hibiscus tiliaceus.
