    Abstract
    Industrialiatio has show a negative impact ton the environment. Heavy metal such as lead, produced from motor vehicle exhaust and industries, are dangerous for human health. Lead enter to the bodey through water, air and food. Lead poisoning can destroy body systems, it blocks the activity of any enzymes important in physiological processes and metabolism. Lead also discrubs the synthesis of hemoglobin and the activity ?-ALAD (delta aminolevulinic acid dehydratase). Chitosan is a natural biopolymer that binds to heavy metal. The ability of chitosan to absorb heavy metal in factory waste has beeb shown preonously. But use of chitosan as a chelating agent in vivo has not been tested. The afficacy of chitosan is influenced by weight of the chitosa and the extern deacetylation in the molecule. The present research aimed to test the influence of the moleculer weight of chitosan on the concentration of lead in the blood, the concentration of hemoglobin and activity of ?-ALAD in mice which have been adminintered lead. This study used 30 Balbc male mice, with a weight of 30-45 g. the animals were divided into 10 groups, all animals received treatment 0,1 Ml/Kg body weight perday for 14 days. The ten groups were the aqua control (K0), the chitosan control (K1), the Pb control (K2), the asetat acid control (K3), and group of treatment Pb + chiitosan LM 1% (P1), Pb + chitosan LM 2% (P2), Pb + chitosan MM 1% (P3), Pb + chitosan MM 2% (P4), Pb + chitosan HM 1% (P5), and Pb + chitosan HM 2% (P6). Blood sampels were to determine hemoglobin concentration, lead concentration and activity of ?-ALAD. The data was processed by SPSS 13 program using theANOVA test followed by the LSD test. The results of analysis are: (1) the adminitration of chitosan of low, medium or high molecular weight and concentration of 1% or 2% results in significanly different hemoglobin concentration as compared to group of K1 and K2, (2) the hemoglobin concentration in the group in the treated with chitosan of any molecule weight or concentration not significanly different, (3) group given of chitosan of any molecular weight or concentration did not differ significanly in lead concentration as compared to the control groups (4) group given of low chitosan an medium molecular weight chitosan of any concentration significanly ?-ALAD activity, (5) group administered moleculer or weigght chitosan showed significanly ?-ALAD activitty as compared to groups P1, P2, P3 and P4. Based on the results above, we conclud that chitosan can reduce the concentration of lead in the blood, and increas improve hemoglobin concentration. Mechanism by wich chitosan effect the activity of ?-ALADmust be determined by the research.
     
    Industrialisasi berdampak negatif terhadap lingkungan. Buangan asap kendaraan bermotor dan pabrik menghasilkan logam berat plumbum yang berbahaya bagi kesehatan manusia. Plumbum masuk ke tubuh manusia melalui air, udara, dan makanan. Keracunan plumbum dapat merusak hampir semua sistem tubuh. Daya racunnya menghambat kerja enzim pada proses fisiologis dan metabolisme tubuh. Plumbum juga mengganggu sistem sintesa hemoglobin dan aktivitas ?-ALAD. Kitosan merupakan biopolimer alami yang mampu mengikat logam berat. Kemampuannya tersebut telah diuji pada banyak penelitian. Namun penggunaan kitosan sebagai pengikat logam berat secara invivo belum pernah diteliti. Kemampuan kitosan mengikat logam berat dipengaruhi oleh berat molekul dan derajat deasetilasi yang dimilikinya. Penelitian ini bertujuan untuk mengetahui apakah ada pengaruh berat molekul kitosan terhadap kadar plumbum darah, kadar hemoglobin dan aktivitas ?-ALAD pada mencit yang telah dipapar plumbum. Penelitian menggunakan 30 ekor mencit jantan strain BALBC, dengan berat badan 30-45g. Sampel dibagi 10 kelompok, perlakuan dengan volum 0,1mL/KgBB setiap hari selama 14 hari. Sepuluh kelompok terdiri dari; kontrol aqua (K0), kontrol kitosan (K1), kontrol Pb (K2), kontrol as. Asetat (K3), kelompok Pb + kitosan LM 1% (P1), Pb + kitosan LM 2% (P2), Pb + kitosan MM 1% (P3), Pb + kitosan MM 2% (P4), Pb + kitosan HM 1% (P5), Pb + kitosan HM 2% (P6). Darah sampel diambil untuk menentukan kadar plumbum, hemoglobin dan aktivitas ?-ALAD. Data penelitian diolah dengan program SPSS 13 menggunakan uji ANOVA dan uji lanjutan dengan uji BNT. Hasil analisis diperoleh; (1) Pemberian kitosan pada berat molekul rendah, sedang dan tinggi pada konsentrasi 1% dan 2% lebih tinggi dan berbeda signifikan terhadap kadar hemoglobin darah kelompok K1 dan K3, (2) kadar hemoglobin pada kelompok perlakuan kitosan pada berat molekul rendah, sedang, dan tinggi pada konsentrasi 1% dan 2% tidak berbeda signifikan terhadap kelompoknya, (3) pemberian kitosan pada berat molekul rendah, sedang dan tinggi pada konsentrasi 1% dan 2% tidak berbeda signifikan terhadap kadar plumbum darah mencit kelompok kontrol, (4) pemberian kitosan pada berat molekul rendah dan sedang pada konsentrasi 1% dan 2%, aktivitas enzim ?-ALAD lebih rendah dan berbeda signifikan terhadap kelompok kontrol kecuali terhadap K2, (5) pemberian kitosan pada berat molekul tinggi pada konsentrasi 1% dan 2% aktivitas ?-ALAD lebih tinggi dan berbeda signifikan terhadap kelompok P1, P2, P3, dan P4. Kesimpulannya bahwa kitosan berpotensi menurunkan kadar plumbum darah dan meningkatkan kadar hemoglobin. Pengaruh kitosan terhadap aktivitas ?-ALAD belum diketahui mekanismenya sehingga masih perlu dilakukan penelitian lanjutan.
