Lampiran 4. Cara Pemeliharaan, Pemberian Jus Mengkudu, Dekapitasi dan Pengambilan Cairan Bronchoalveolar a. Cara pemeliharaan Tikus wistar yang dipilih berumur sekitar 15 minggu dengan berat badan rata-rata 200 gram, dipelihara pada kandang selama 30 hari. Masing-masing kandang diisi 5 ekor tikus. Tikus diberi makan dan minum yang sama. b. Cara memegang tikus dan pemberian jus mengkudu Pengambilan tikus dari kandang dilakukan dengan mengambil ekornya, kemudian tikus diletakkan di atas kasa, selanjutnya bagian punggung tikus dipegang dengan telapak tangan dengan jari-jari memegang bagian leher sehingga kepala tikus dalam posisi terangkat ke atas untuk pemberian jus mengkudu melalui sonde. c. Cara dekapitasi dan pengambilan cairan bronchoalveolar 1) Tikus wistar diterminasi dengan dekapitasi leher, dengan cara meletakkan tikus di atas permukaan rata. Sebuah pinset diletakkan di atas kuduk tikus. Sambil menekan pinset, ekor tikus ditarik kuat dan pinset diarahkan ke atas kepala tikus. 2) Tikus kemudian diletakkan pada posisi terlentang dan seluruh permukaan leher sampai ventral disiram dengan alkohol 70%. 3) Dibuat irisan kecil melalui sayatan ventral garis tengah sekitar 5 cm panjang di leher. Kulit dirobek dengan menggunakan pinset hingga kulit terkelupas, dan tampak rongga pleura.

4) Trakhea yang terlihat dihubungkan dengan kanula dengan tabung polietilen yang terhubung dengan jarum suntik dengan ukuran 20G, kemudian paru-paru dicuci dengan dimasukkan 3 ml larutan PBS, dilakukan beberapa kali hingga didapatkan cairan bronchoalveolar dengan jumlah yang cukup.

Lampiran 5. Cara Pembuatan Reagen Griess dan Standard Nitrit
a. Cara membuat reagen Griess: Reagen1: N-(1-naphthyl) ethylenediamine dihydrochloride = NED (Sigma): 0,1 gram dilarutkan dalam 100 ml air suling. Reagen 2: Sulfanilamide (Sigma): 1 gram dilarutkan dalam 100 ml HCl 4 N. Reagen 1 dan reagen 2 harus disimpan dalam almari pendingin dalam botol gelap dan dapat digunakan dalam 6 minggu atau selama tidak berubah warna menjadi lebih gelap. Reagen Griess: mencampur dengan volume sama banyak antara reagen 1 dan reagen 2 setiap akan digunakan. Reagen siap digunakan dalam 1 jam setelah pencampuran. b. Cara membuat Standard Nitrit : 69 mg NaNO2 dilarutkan dalam 500 ml air suling ( 2mM stok), kemudian dibuat pengenceran bertingkat dari 0 – 200 uM dengan cara melarutkan larutan stok menggunakan medium yang dipakai untuk kultur makrofag.
