Abstract

The Ito cell (fat-storing cell) is a cell lying in perisinusoidal space of liver. The function of Ito cell is expanding from a site of fat-storing site to a center of extracellular matrix metabolism and mediator production in the liver. This study was performed in order to evaluate the Ito cells in cholestatic condition. The artificial cholestatic was conducted by ligation of extrahepatic bile ducts (bile duct ligation = BDL) in broilers. The results showed that BDL induced bile congestion, fibrosis, proliferation of Ito cells and intrahepatic bile ductules. Immunohistochemistry demonstrated that Ito cells were scattered throughout the fibrotic areas, and larger in size with more extensive immunoreactivity than those in normal livers. Ultrastructural study demonstrated that Ito cells were closely associated with the production of extracellular collagen fibers. Ito cells actively react against hepatocytic injuries, especially in fibrogenesis of cholestatic livers.   Key words: Bile duct, ito cell, broiler

Abstract

Q fever is a zoonotic disease caused by Coxiella burnetii, a species of bacteria that is distributed globally. Ruminant especially sheep and goats may play an important role in the transmission of the disease to human. The research of seroprevalence of Q fever in sheep and goats was carried out from August 2006 to March 2007 in West Java area. A total of 138 sera were collected; 69 sera from sheep and 69 sera from goats. The indirect immunoflourescent antibody test was used to determine the seroprevalence of Q fever. The seropositive based on the dilution of serum starting from 1 : 16. Seropositive were observed in 22 samples (31.88%) of sheep and 14 samples (20.28%) of goats. The highest titer of 1 : 128 was observed in 3 pregnant sheep. The results of the present study suggested that Q fever was endemic in West Java area.

Abstract

Asam valproat memengaruhi aktivitas histone deacetylase yang berperan dalam ekspresi gen selama organogenesis. Insulin berperan dalam proliferasi dan diferensiasi sel-sel saraf dentate gyrus hipokampus. Penelitian ini bertujuan mempelajari pengaruh pemaparan asam valproat pada induk bunting terhadap ekspresi gen insulin pada dentate gyrus. Penelitian dilakukan di UPHL IPB pada bulan Mei 2015 hingga Desember 2016 dengan  84 ekor anak tikus yang dilahirkan oleh induk tikus kontrol yang diberi asam valproat 250 mg pada umur kebuntingan 10, 13, dan 16 hari digunakan untuk pengamatan kadar glukosa, insulin, DNA, RNA, dan rasio RNA/DNA serta pengamatan mikroskopis otak. Pengamatan dilakukan selang waktu empat minggu, dimulai dari umur 4 sampai 32 minggu. Anak tikus yang dilahirkan oleh induk tikus yang diberi asam valproat selama kebuntingan mempunyai kadar glukosa otak yang lebih tinggi (p<0,01) dan insulin yang lebih rendah (p<0,05).  Selama periode pertumbuhan, anak tikus yang dilahirkan oleh induk tikus yang diberi asam valproat mengalami peningkatan kadar glukosa dan penurunan kadar insulin (p<0.05). Pengamatan mikroskopis sel-sel dentate gyrus menunjukkan degenerasi sel dan tidak terlihat reaksi imunoreaktif terhadap insulin, namun terjadi penurunan konsentrasi DNA, RNA, serta rasio RNA/DNA (p<0,05). Pemberian asam valproat pada induk tikus pada umur kebuntingan 10, 13, dan 16 hari memengaruhi organogenesis otak anak tikus sehingga menyebabkan kerusakan sel-sel saraf penghasil insulin otak yang ditunjukkan oleh  penurunan sekresi dan kadar insulin.

Insulin plays a role in regulating the proliferation and differentiation of the dentate gyrus. This experiment was designed to study the effects of valproic acid administration on the expression of insulin gene in the dentate gyrus of pregnant rats.  This study was carried out at the Laboratory Animal Management Unit (UPHL) of Bogor Agricultural University  from May 2015 to December 2016, with eighty four newborn rats from control rats and VA-administered rats at the age of 10, 13, and 16 days of pregnancy. The measurements were done for glucose, insulin, DNA, and RNA concentrations in dentate gyrus and to observe the microscopic condition of the brain at the ages of 4 to 32 weeks with 4 weeks interval.  Rats born form mothers administered by 250 mg valproic acid during pregnancy had higher glucose concentrations (p<0.01) and lower insulin concentrations (p<0.05) in the dentate gyrus. During the post-natal growth phase, rats born from mothers administered with valproic acid had increased glucose concentrations and decreased insulin concentrations (p<0.05). Microscopic observations of the dentate gyrus showed degeneration of nerve cells with no immunoreaction to insulin was seen in dentate gyrus cells. However, the concentrations of DNA, RNA, and the ratio of RNA/DNA in the dentate gyrus cells decreased (p<0.05). The administration of valproic acid to pregnant rats at the age of 10, 13, and 16 days of pregnancy destructs  brain organogenesis of the offsprings which eventually disturbs insulin production in the dentate gyrus indicated by decreased insulin secretion and concentrations.  [MKB. 2017;49(3):156–64]Key words: Dentate gyrus, insulin, organogenesis, valproic acid

Abstract

The objective of this study was to analyze changes in body weight and cell morphology in liver, kidney and brain tissue of Sprague dawley rats administered  hypercholesterolemia diets for four weeks. Four diet treatments were applied in this study: control, catfish oil, catfish oil with the addition of omega 3 and catfish oil with the addition of omega 3 and vitamin E. Four weeks after the intervention, the rats were sacrificed and the internal organs (liver, brain, and kidney) were taken for histological preparations by hematoxylin-eosin (HE) and immunohistochemistry test. The study showed that the catfish oil intervention tend to reduced weight gain of rats fed hypercholesterolemia diets. More lipid accumulation in liver of the control group was found than the intervention groups. However, there was no difference in the histopathology of the kidney and brain tissues between the control group and intervention groups. It is concluded that catfish oil study provides a positive effect in rat liver tissue, but no difference exists between the brain and kidney tissue. There is no defect found at hippocampus of rats by formed of amyloid plague.

Abstract

The study aimed to analyze the potential of okra to reduction blood glucose and MDA liver in streptozotocin (STZ)-induced diabetic rats. Design experiment used in this study was pre and post test controlled group design. The first step of this study was analyzed bioactive compound of okra extract. The next step was administired orally of okra extract to control and diabetic rats induced by streptozotocin 50 mg/kgBW for 14 days. Sprague dawley rats were divided into six groups: normal control (N), diabetic control (DM), diabetic treated with green okra extract (GOE) with the dosage of 5 mg/kgBW quercetin and 10 mg/kgBW quercetin, diabetes treated with purple okra extract (POE) with the dosage of 5 mg/kgBW quercetin and 10 mg/kgBW quercetin. Blood glucose were measured each five days and malondialdehyde (MDA) liver in rats were measured in the end of intervention. The following results show that phenolic and quercetin of purple okra extract were higher (3.60%; 0.45 mg/g) than green okra extract (3.58%; 0.27 mg/g). Administration of GOE I, GOE II, POE I and POE II in diabetic rats showed significant (P<0.05) reduction in blood glucose level (115.25 mg/dl; 86 mg/dl; 180.75 mg/dl; 91 mg/dl) and improve level of MDA. These results suggest that intervention of okra extract based on quercetin compound show an antihyperglicemic potential and improve MDA level.

Abstract

Highly  pathogenic avian influenza (HPAI) H5N1 virus is a known pathogen in birds. Recently, the virus has been reported to cause sporadic fatal disease in tigers, leopards, and other exotic felids as well as domestic cats  in Thailand. The present study was carried out to investigate the presence of AI H5N1 virus infection in stray cats roaming around residential, traditional and chicken farms in Bogor, West Java. Ninety serum samples were tested using HI test to screened for the presence of antibody to AI H5N1. Virus isolation was done in SPF embrionated chicken eggs and identify using HI, AGP and RT-PCR. The results showed that 18,9% of stray cats developed antibodies against H5 with geometric mean titre 23,1 . Stray cats lived in traditional markets 18–40% developed antibodies in the titre ranging from 22,8  to 24,5. Only two out of nine stray cats which lived in chicken farm developed low antibody titres again H5 (21). None of the stray cats lived in residencial area have developed antibodies against H5. This study revealed that stray cats have been contact with AI H5. Avian influenza H5 viruses were isolated in eight out of 33 pooled of rectal swab samples. The viral cleavage site sequences are CCTCAAAGAGAGAGC AGAAGAAAGAAGAGAGGT which represent amino acid sequences of PQRESRRKKRG. Based on the cleavage site sequence, the isolates are similar with the AI H5 virus subtype isolated from human in Indonesia during 2005–2007.

Abstract

Aterosklerosis pada arteri iliak berkaitan dengan kejadian peripheral arterial disease (PAD) pada manusia. Penelitian ini bertujuan untuk menganalisis lesio aterosklerosis pada arteri iliak sebagai salah satu faktor penyebab PAD. Penelitian ini menggunakan sembilan monyet ekor panjang jantan dewasa dari 3 kelompok respons yang diberi pakan aterogenik IPB-1 selama 2 tahun. Arteri common iliak diambil pada saat nekropsi, diproses menjadi slaid histologi dan diwarnai dengan Verhoeff van Giesson (VVG). Keparahan lesio dikategorikan sebagai grade I sampai VI dan dianalisis secara deskriptif. Area lesio ditentukan melalui panjang lamina elastik interna (PLEI), area intima (AI), serta ketebalan maksimum intima (KIM) dan dianalisis dengan ANOVA. Hasil penelitian menunjukkan 55,56% monyet membentuk lesio plak aterosklerosis (grade IV sampai VI) yang mana mereka berasal dari kelompok intermediet dan hiper-responsif. Kelompok hiper-responsif menunjukkan AI dan KMI paling tinggi (0,979 mm2; 0,352 mm) diikuti kelompok intermediet (0,372 mm2; 0,237 mm) dan kelompok hipo-responsif (0,049 mm2; 0,052 mm) (P<0,05). Hasil ini menunjukkan semakin tinggi kolesterol plasma, semakin luas area lesio yang terbentuk. Keseluruhan hasil mendukung bahwa monyet yang diberi pakan aterogenik IPB-1 selama 2 tahun mampu membentuk lesio plak aterosklerosis pada arteri common iliak, dan berpotensi sebagai hewan model PAD, kecuali kelompok hipo-responsif.
