Diabetes Mellitus (DM) is metabolic disease characterized hyperglicemia caused by abnormalities of insulin secretion, insulin sensitivity, or both of them.  Persistent hyperglicemia can trigger the production of oxidative stress. Oxidative stress can cause  glomerular hypertrophy. Coriander seed extract has the potential to overcome oxidative stress. This study aims to determine the effect of coriander seed extract to kidney histopathological examination, blood cholesterol, and blood sugar level in hypercholestrolemia diabetic rats. Samples consist of 30 males wistar rats were divided into five treatments i.e: (K1) standard feed and aquades, (K2) high-fat feed, alloxan, and  glibenclamid 0,045 mg/day, (K3) high-fat feed, alloxan, and coriander seed extract 300 mg/kgBW/day, (K4) high-fat feed, alloxan, and coriander seed extract 500mg/kgBW/day, (K5) high-fat feed, alloxan, and  coriander seed extract 700mg/kgBW/day. Coriander seed extract was given for 28 days. The result of Wilcoxon test showed that coriander seed extract can reduce blood cholesterol level in diabetic hypercholesterolemia, meanwhile the result of paired T-test showed that it can reduce blood sugar level. Measurement of kidney’s histopathological structure as glomerular area was analyzed by Kruskal Wallis test (p=0,001) and continued with Mann-Whitney test. Group K4 can reduce glomerular area significantly compared with group K3 and K5. In conclussion, coriander seed extract can reduce blood cholesterol, blood sugar level and effectively reduce glomerular hypertrophy at dose of 500mg/kgBW/day. Keyword : Coriandrum sativum L.; coriander seed extract; glomerular hypertrophy; blood cholesterol level; blood  glucose level ABSTRAK Diabetes Melitus (DM) merupakan suatu penyakit metabolik dengan karakteristik  hiperglikemi yang terjadi karena kelainan sekresi insulin, kerja insulin atau kedua-duanya. Hiperglikemi persisten dapat memicu produksi stres oksidatif. Stres oksidatif dapat menyebabkan terjadinya hipertrofi glomerulus. Ekstrak biji ketumbar (Coriandrum sativum L.) berpotensi mengatasi stres oksidatif. Penelitian ini bertujuan untuk mengetahui efek pemberian esktrak biji ketumbar (Coriandrum sativum L.) terhadap gambaran histopatologi ginjal, kadar kolesterol darah, dan kadar gula darah tikus model hiperkolesterolemia diabetes. Sebanyak 30 ekor tikus putih jantan galur wistar, dikelompokkan menjadi lima kelompok dengan perlakuan berbeda yaitu: (K1) pakan standar dan aquades, (K2) pakan tinggi lemak, aloksan, dan glibenklamid 0,045mg/hari, (K3) pakan tinggi lemak, aloksan dan ekstrak biji ketumbar 300mg/kgBB/hari, K4) pakan tinggi lemak, aloksan dan ekstrak biji ketumbar 500mg/kgBB/hari, (K5) pakan tinggi lemak, aloksan, dan ekstrak biji ketumbar 700mg/kgBB/hari. Ekstrak biji ketumbar diberikan selama 28 hari. Hasil uji Wilcoxon menunjukkan ekstrak biji ketumbar dapat menurunkan kadar kolesterol darah, sedangkan hasil uji T berpasangan menunjukkan ekstrak biji ketumbar dapat menurunkan kadar guka darah sewaktu pada tikus model hiperkolesterolemia diabetes. Histopatologi ginjal dianalisis menggunakan uji Kruskal Wallis didapatkan (p=0,001) dan dilanjutkan dengan uji Mann-Whitney. Pada kelompok K4 terdapat penurunan luas glomerulus yang signifikan dibanding kelompok K3 dan K5. Kesimpulannya, esktrak biji ketumbar dapat menurunkan kadar kolesterol darah, kadar gula darah, dan pada dosis 500mg/kgBB/hari paling efektif untuk menurunkan hipertrofi gomerulus.

Abstract Background Diabetes, a global cause of mortality in developing countries is a chronic disorder affecting the metabolism of macromolecules and has been attributed to the defective production and action of insulin characterized by persistent hyperglycemic properties. This global disorder harms organs of the body such as the liver, kidney and spleen. Medicinal plants such as Hunteria umbellate have been shown to possess hypoglycemic, antioxidative and anti-diabetic properties owing to the high concentration of active phytochemical constituents like flavonoids and alkaloids. The present study seeks to evaluate the hypoglycemic activities of ethanolic seed extract of Hunteria umbellate on streptozotocin-induced diabetes rats. Methods Thirty (30) female experimental rats were randomly divided into five groups with six rats per group and were administered streptozotocin (STZ) and Hunteria umbellate as follows. Group 1 served as control and was given only distilled water, group 2 rats were administered 60 mg/kg STZ; Group 3 was administered 60 mg/kg STZ and 100 mg/kg metformin; group 4 rats were administered 60 mg/kg STZ and 800 mg/kg Hunteria umbellate, group 5 rats 60 mg/kg STZ and 400 mg/kg Hunteria umbellate. The fasting blood glucose level of each rat was measured before sacrifice. Rats were then sacrificed 24 h after the last dose of treatment. Results The results showed that Hunteria umbellate significantly reversed STZ-induced increase in fasting blood glucose and increase in body and organs weight of rats. Hunteria umbellate significantly reversed STZ-induced decrease in antioxidant enzyme in liver, kidney and spleen of rats. Hunteria umbellate significantly reversed STZ-induced increase in oxidative stress markers in liver, kidney and spleen of rats. Conclusion Collectively, our results provide convincing information that inhibition of oxidative stress and regulation of blood glucose level are major mechanisms through which Hunteria umbellate protects against streptozotocin-induced diabketes rats.
