Daftar Isi:
- To do research and development of antidiabetic drugs, animal models of diabetes in accordance with the conditions is required. The aim of this research was to develop a diabetic model that is fit to the pathophysiology of diabetic condition. The pregnant female rats were divided into 2 groups, one group was orally treated by a single dose of valproic acid (250 mg/kg bw) on day 9th of pregnancy and the other was a control. At the ages of 8, 16 and 24 weeks the blood samples of litters (F1) were taken for glucose, insulin and triglyceride determination. At the same time, pancreatic tissues were collected under deep anesthetic condition for immunohistological study. Results of blood glucose concentrations and histological finding of litters (F1) indicated that at the age of 8 weeks both had showed a similar pattern as compared to control. At the ages of 16 and 24 weeks, blood glucose and insulin level showed a significant increase, while positive insulin cells slightly decreased in number. It can be concluded that treating rat with valproic acid on days 9 of gestation will inhibit pancreatic β cells function. There is an indication that F1 of valproic acid treated pregnant mother start showing a metabolic syndrome at 16 weeks and being pronounce by aging.
- Untuk melakukan penelitian dan pengembangan obat antidiabetes diperlukan hewan model yang sesuai dengan kondisi diabetes. Tujuan penelitian ini ialah untuk mengembangkan model diabetes yang sesuai kondisi patofisiologi diabetes. Induk tikus yang telah bunting dibagi dalam 2 kelompok, satu kelompok diberi asam valproat 250 mg/kg bb per oral pada kebuntingan hari ke-9 dan kelompok lain sebagai kontrol. Pada umur anak tikus (F1) 8, 16 dan 24 minggu diambil sampel darah untuk dianalisis kadar glukosa, kadar insulin dan trigliserida. Pada waktu yang sama, jaringan pankreas diambil dalam kondisi teranestesi untuk dilakukan immumunohistokimia. Hasil pengukuran kadar glukosa dan histologi pada tikus (F1) umur 8 minggu belum menunjukkan adanya perbedaan yang bermakna dibanding kontrol normal. Pada tikus (F1) umur 16 dan 24 minggu kadar glukosa darah dan konsentrasi insulin serum menunjukkan peningkatan yang signifikan, sedangkan sel yang positif insulin menurun. Dapat diambil kesimpulan pemberian asam valproat pada tikus pada hari ke-9 kebuntingan dapat menghambat fungsi sel β pankreas. Dengan demikian dapat disimpulkan tikus (F1) yang induknya diberi asam valproat pada masa kebuntingan dapat menyebabkan sindrom metabolik yang dimulai pada umur 16 minggu dan berlanjut sampai usia tua.
