"ABSTRAKThe existence of chioramphenicol residues in veterinary products could cause such a serious side effect like aplastic anemia. A specific and sensitive ELISA method to detect chioramphenicol residues was needed to be developed in order to get a more efficient and economical analysing method. In this study, a direct ELISA method has been done using chioramphenicol-bovine serum albumin (CAP-BSA) as antigen and antisera chioramphenicol labelled by enzyme horseradish peroxidase (HRP) as antibody. CAP-BSA with a dilution of 1:200 and antisera chioramphenicol labelled by }iRP with a dilution of 1:125 showed a limit detection of 0.05 ng/ml. CAP-BSA had been synthesized from chloramphenicol sodium succinate and BSA, using mixed anhydride reaction, whereas HRP-labelled antisera chloramphenicol had been synthesized from antisera chioramphenicol and FIRP, using periodate conjugation technique. The production of antisera chloramphenicol has been performed through CAP-BSA immunization using two New Zealand White rabbits resulting in antisera chloramphenicol with a less satisfactory specificity and sensitivity. The recovery assay of chloramphemcol in cow milk gave 98,17% ± 2,88% yield.

"Written in an easy-to-read style, it contains special features such as a simple approach to what is often regarded as a complicated subject; liberal use of simple and informative diagrams; and an introduction to AIDS in the context of immunology."

"PendahuluanStomatitis Aftosa Rekuren (SAR) adalah suatu penyakit mulut yang paling sering ditemukan kini amat mengganggu penderitanya karena hilang tirnbul (rekurest) sehingga dapat mengganggu fungsi pengunyahan (1;2). SAR biasanva mengenai jaringan lunak yang tidak berkeratin, bentuknya bulat, dikelilingi "halo" berbatas jelas dan terasa sakit (2,3,4). Etiologi SAR sampai saat ini belum diketahui dengan pasti, namun ada beberapa faktor predisposisi yang diduga turut berperan pada putogenesisnya, antara lain faktor genetik, hormonal, imunologis, psikologis, infeksi mikroorganisme, derisiensi vitamin ataupun allergi (2,3,4,5), Karen belum diketahui penyebab utamanya maka bagaimana mekanisme sampai terjadinya SAR (patogenesis) secara pasti belum terungkap. Oleh karena itu penanganan SAR yang telah diupayakan selama ini belum mencapai hasil yang optimal. Seiring dengan kemajuan di bidang imunologi maka beberapa penelitian akhir-akhir ini menemukan adanya ketidakseimbangan imunologis pada penderita SAR yaitu dengan ditemukannya perubahan proporsi subpopulasi limfosit di daerah tepi oleh Leiner (6,7,8) dan ternyata perubahan tersebut semakin nyata pada SAR tipe mayor (9)."

"The aim of this volume is to summarize current knowledge on the cellular and molecular aspects of the aging immune system, with an emphasis on infectious diseases and new therapeutic approaches."
