Perkembangan paru yang terjadi sejak masa embrio hingga pascanatal menentukan efektivitas pertukaran gas, khususnya pada alveolus. Penelitian mengenai struktur ketebalan dinding alveolus paru dan kaitannya dengan diameter alveolus pascanatal belum pernah dilaporkan. Penelitian ini bertujuan untuk mengetahui hubungan antara ketebalan dinding alveolus paru dengan panjang diameter alveolus pada perkembangan paru neonatus tikus Sprague-Dawley. Jaringan paru tikus Sprague Dawley usia 2, 4, 10, dan 16 hari yang telah diproses secara histologis dengan pewarnaan Trichrome Masson, diamati dan difoto di bawah mikroskop, kemudian diukur ketebalan dinding dan panjang diameter alveolus-nya dengan Optilab Image Raster. Data disajikan masing-masing dalam bentuk proporsi total ketebalan dinding alveolus atau panjang diameter alveolus terhadap total panjang horizontal garis di sepertiga lapang pandang foto. Hasil penelitian menunjukkan adanya peningkatan ketebalan dinding alveolus paru dan penurunan panjang diameter alveolus dengan korelasi negatif sedang (uji Pearson; r=-0,523; p=0,009). Disimpulkan bahwa peningkatan ketebalan dinding alveolus berkorelasi dengan penurunan panjang diameter alveolus pada paru neonatus tikus Sprague Dawley. ...... Lung development, which happens during embryonic period until postnatal, will determine the effectiveness of the gas exchange process. Until recently, study about the thickness of septum interalveolar and the diameter length of alveolus has not been reported yet. This study aimed to know the correlation between the thickness of septum interalveolar and the diameter length of alveolus on postnatal lung development of Sprague Dawley rat. The Sprague Dawley rats aged 2, 4, 10, and 16 days tissues that were processed histologically with Masson’s Trichrome stain were observed and photographed using microscope. Subsequently, the septum interalveolar and diameter were measured by using Optilab Image Raster. The data were presented each in ratio of total alveolar septum or total alveolar diameter to the horizontal length of one-third visual field. Our study showed that there is a significant moderate correlation between the thickness of septum interalveolar and the diameter length of alveolus on Sprague Dawley rat (Pearson’s test; r=-0.523 ; p=0.009). As summary, the septum interalveolar increase while the diameter decrease on lung development of postnatal Sprague Dawley rat.

Alveolus neonatus mengalami perkembangan dalam hal jumlah dan ukuran pada masa pascanatal. Pada perkembangan tersebut, jumlah alveolus bertambah dan dimensi alveolus – dalam hal diameter – meningkat bersama dengan peningkatan volume total paru. Penelitian ini bertujuan mencari korelasi panjang diameter alveolus dengan usia pada perkembangan paru neonatus. Desain penelitian merupakan potong lintang dalam studi analitik observational. Empat kelompok tikus Sprague-Dawley usia 2, 4, 10, dan 16 hari digunakan sebagai model coba. Paru tikus yang telah dijadikan sediaan histologis difoto di bawah mikroskop untuk kemudian diukur dengan program Optilab Image Raster. Panjang diameter alveolus paru tikus Sprague-Dawley diukur pada sepertiga tengah lapang pandang dengan metode proporsi, yaitu membandingkan total panjang diameter alveolus pada satu lapang pandang dengan total panjang lapang pandang. Hasil penelitian menunjukkan bahwa rerata panjang diameter alveolus mengalami penurunan dari 0,466 (SD 0,093) pada usia 4 hari menjadi 0,401 (SD 0,126) pada usia 16 hari. Namun, korelasi usia dan panjang diameter alveolus tidak signifikan dengan kekuatan korelasi lemah (Spearman, p = 0,451 dan r = -0,162). Disimpulkan bahwa panjang diameter alveolus paru tidak berkorelasi dengan usia perkembangan neonatus tikus Sprague-Dawley. ...... Alveolar changes in amount and size occur in lung morphogenesis during post-natal development. During the development, the amount of alveolar multiplies and the alveolar dimension – measured in diameter – expanses as the total lung volume increases until alveoli reach its mature age. This study aimed to find a correlation between alveolar diameter and age during post-natal development. The research design was cross sectional, an analytic observational study. Four groups of Sprague-Dawley rats, i.e. 2, 4, 10, and 16 days-old were used as model. Rats' lungs that have been processed histologically were captured as photos under light microscope, and were measured using Optilab Image Raster. The alveolar diameter was measured using ratio of the total length of the diameter and total length of horizontal field on one-third middle of the field. Mean length proportion of alveolar diameter were found decreasing from 0,466 (SD 0,093) at age 4 day to 0,401 (SD 0,126) at age 16 day. However, correlation between alveolar diameter sizes in post-natal ages was insignificant with low correlation power (Spearman p = 0,451 and r = -0,162). In conclusion, alveolar diameter has no correlation with age during lung development of Sprague-Dawley rat's neonates.
