"berkembang semakin masif setiap tahunnya dengan risiko komplikasi, di antaranya berupa kardiomiopati. Pengobatan tradisional berupa daun delima (Punica granatum) dapat menjadi alternatif bagi pengobatan konvensional diabetes mellitus. Tujuan: Mengetahui potensi ekstrak daun delima sebagai agen antihiperglikemik dan kardioprotektif.Metode: Penelitian dilakukan terhadap 20 tikus Sprague dawley diabetes yang sebelumnya telah diinduksi menggunakan aloksan, dan 4 tikus normal. Tikus tersebut dikelompokkan dalam 6 kelompok, yaitu kelompok normal, kontrol positif, kontrol negatif, dan 3 kelompok perlakuan yang masing-masing diberikan ekstrak dosis 200mg/kg berat badan (BB), 400 mg/kgBB, dan 600 mg/kgBB. Pengukuran gula darah puasa (GDP) dilakukan sebelum perlakuan dan setiap 4 hari selama perlakuan berlangsung, selama 16 hari. Setelah perlakuan, dilakukan uji histopatologi teknik pewarnaan hematoksilin-eosin terhadap jantung tikus. Hasil: Kelompok perlakuan dengan pemberian dosis ekstrak 400 mg/kgBB dan 600 mg/kgBB menunjukkan penurunan GDP tikus yang signifikan jika dibandingkan dengan kontrol negatif. Dosis 600 mg/kgBB merupakan dosis yang dinilai paling efektif. Ujihistopatologi menunjukkan kardiomiopati pada kelompok kontrol negatif dan kelompok perlakuan dengan dosis 200 mg/kgBB dan 400 mg/kgBB, sementara kelompok normal, kontrol positif, dan perlakuan dengan dosis 600 mg/kgBB tidak menunjukkan kelainanspesifik. Kesimpulan: Ekstrak daun delima menunjukkan efek antihiperglikemik dan kardioprotektif melalui uji In Vivo. Dosis efektif esktrak daun delima adalah 600 mg/kgBB.Background: Diabetes mellitus is a global health problem that is developing massively every year with risks of complications, one of which is cardiomyopathy. Traditional remedies such as pomegranate (Punica granatum) leaf can be an alternative to conventional treatment of diabetes mellitus. Objective: To study the potential of pomegranate leaf extract as antihyperglycemic and cardioprotective agent.Methods: This research was done to 20 alloxan-induced diabetic rats and 4 normal rats. Those rats are grouped into 6 groups, which includes normal group, positive control group, negative control group, and 3 groups treated with the exctract by the dose of 200mg/kg body weight (BW), 400 mg/kgBW, and 600 mg/kgBW. Measurements of fasting blood sugar (FBS) were done before the treatment, and every 4 days during the 16 days the research was conducted. After the treatments were given, histopathology test ofhematoxylin-eosin staining was done to the hearts of the rats.Results: The groups treated with the 400 mg/kgBW and 600 mg/kgBW dose extract showed significant decreases in FBS compared to the negative control group. The 600 mg/kgBW dose is considered as the most effective dose. Histopathology evaluation showed cardiomyopathy in the negative control group and the groups treated with 200 mg/kgBW and 400 mg/kgBW extract, while the normal group, positive control group, and the group treated with 600 mg/kgBW extract showed no specific disorder. Conclusion: The pomegranate leaf extract showed antihyperglycemic and cardioprotective effect through In Vivo experiment. The effective dose of pomegranate leaf extract is 600 mg/kgBW."

"Latar Belakang: Human platelet lysate (HPL) telah menjadi alternatif pengganti fetal bovine serum (FBS) dalam kultur sel. Penggunaan platelet yang telah melewati masa simpan belum diketahui dalam kultur HUVEC. Tujuan: Mengetahui pengaruh masa simpan platelet pada HPL terhadap efektivitas pengganti FBS dalam kultur HUVEC. Metode: Sel HUVEC dikultur dengan FBS, HPL fresh, dan HPL extended dan diuji dengan uji MTT dan Bradford. Hasil: Suplementasi HPL menghasilkan viabilitas dan protein total yang lebih tinggi dibandingkan dengan FBS. Viabilitas tertinggi dihasilkan oleh HPL extended dan protein total tertinggi dihasilkan HPL fresh. Simpulan: HPL extended dapat digunakan sebagai pengganti FBS dalam kultur HUVEC.

Background: Human platelet lysates (HPL) has been proved to be FBS alternatives in cell culture. Platelet that passes its shelf-life in HUVEC culture has not been studied previously.

Objective: To evaluate the effectiveness of platelet shelf-life to HPL as FBS substitute in HUVEC culture.

Method: HUVEC cultured with FBS, HPL fresh, and HPL extended were tested by MTT and Bradford assay.

Result: Cultures supplemented with HPL has higher cell viability and total protein than FBS supplemented. HUVEC cultured with HPL extended presents the highest cell viability. However, HPL fresh has the highest total protein concentration.

Conclusion: HPL extended can be used as a substitute to FBS in HUVEC culture."

"Latar Belakang: Human Platelet Lysates (HPL) yang berasal dari platelet yang melewati masa simpan belum diketahui efeknya pada kultur HUVEC. Tujuan: Mengevaluasi pengaruh waktu penyimpanan platelet pada HPL terhadap profil protein HUVEC. Metode: HUVEC dikultur dengan FBS, HPL fresh, dan HPL extended diuji dengan SDS-PAGE. Hasil: Intensitas band HPL fresh dan extended cenderung lebih tinggi. Ketebalan band HPL fresh dan extended lebih tinggi dibandingkan FBS pada band 4, dan lebih rendah pada band 3. Kisaran berat molekul protein HPL fresh dan extended tidak berbeda dibandingkan FBS. Simpulan: Profil protein HUVEC menggunakan HPL fresh dan extended identik dengan FBS.

Background: The effect of Human Platelet Lysates (HPL) derived, from platelets that have passed normal shelf life was unknown on HUVEC.

Objective: To determine shelf-life effect on HPL as FBS alternative on HUVEC protein profile. Method: HUVEC were cultured with FBS, fresh, extended HPL, and analyzed with SDS-PAGE. Results: Band intensity of fresh HPL tended to be higher. Band thickness of HPL higher than FBS in band 4th row band, and lower in 3rd row band. No difference were observed in protein molecular weight range between HPL fresh, extended, FBS. Conclusion: HUVEC protein profile cultured with fresh, extended HPL is identical with FBS.
