      Abstract
      Limfonodus merupakan organ limfoid sekunder yang berperan penting dalam respons imun melalui proses penyaringan antigen dan aktivasi sel imun. Penelitian ini bertujuan untuk membuat preparat histopatologi limfonodus prescapularis kucing menggunakan metode FFPE (Fixed-Formalin Paraffin-Embedded) dan mengidentifikasi struktur histologis yang terdapat pada jaringan tersebut. Metode yang dilakukan meliputi pengambilan sampel limfonodus prescapularis, fiksasi menggunakan NBF 10%, trimming, dehidrasi, clearing, infiltrasi parafin, embedding, sectioning, pewarnaan Hematoksilin-Eosin (HE), serta observasi menggunakan mikroskop cahaya. Hasil pembuatan preparat menunjukkan bahwa tahapan preparasi berlangsung dengan baik yang ditandai oleh terbentuknya blok parafin yang padat, irisan jaringan yang utuh, serta terpeliharanya arsitektur limfonodus, namun kualitas pewarnaan HE belum optimal sehingga kontras antara inti sel dan sitoplasma tampak kurang jelas. Identifikasi mikroskopis masih dapat dilakukan dengan ditemukannya struktur utama limfonodus berupa kapsula, korteks dan germinal center, parakorteks, serta medula. Komponen seluler yang berhasil diidentifikasi meliputi limfosit kecil dan centrocyte di korteks, makrofag dan limfosit besar di parakorteks, serta sel plasma pada medula.
       
      The lymph node is a secondary lymphoid organ that plays an important role in the immune response through antigen filtration and immune cell activation. This study aimed to prepare histopathological slides of the feline prescapular lymph node using the FFPE (Fixed-Formalin Paraffin-Embedded) method and to identify the histological structures present within the tissue. The procedures included sampling, fixation in 10% NBF, trimming, dehydration, clearing, paraffin infiltration, embedding, sectioning, Hematoxylin-Eosin (HE) staining, and examination using a microscope. The results showed that the procedures were successfully performed, as indicated by the formation of compact paraffin blocks, intact tissue sections, and preservation of lymph node architecture. However, the quality of HE staining was not optimal, resulting in reduced contrast between the nuclei and cytoplasm. Microscopic identification successfully done, revealing the main lymph node structures, including the capsule, cortex and germinal centers, paracortex, and medulla. The cellular components identified included small lymphocytes and centrocytes are found in the cortex, macrophages and large lymphocytes in the paracortex, and plasma cells in the medulla.
