"Telah dilakukan penelitian laboratorium untuk mengetahui pengaruh pencekokan zat warna C.I. Food Yellow 4 terhadap gejala klinik dan perubahan struktur histologi organ ginjal mencit (Mus musculus L.). Pencekokan dilakukan terhadap 24 ekor mencit yang dibagi dalam 4 kelompok perlakuan dengan dosis : 0,00 (1 ); 5,25 (11); 7,25 (III) dan 9,25 (IV ) gram C.I. Food Yellow 4/kg berat badan mencit dengan pelarut aquabidestilata. Setelah perlakuan gejala klinik yang timbul diamati setiap hari, Pada hari ke-6 semua mencit dikorbankan dengan cara dislokasi serviks dan diambil organ ginjalnya untuk dibuat preparat Histologi. Hasil pengamatan terhadap gejala klinik memperlihatkan bahwa pada semua kelompok perlakuan terjadi diare dan perubahan berat badan yang tidak stabil. Hasil pengujian Kruskal - Wallis pada jurnlah rata-rata kerusakan glomerulus (α = 0,05) menunjukkan adanya perbedaan nyata pada kelompok kontrol dengan semua kelompok perlakuan. Hasil pemeriksaan mikroskopik organ ginjal mencit perlakuan kelompok (II ) tampak kerusakan ringan pada bagian glomerulus. Sedangkan pada kelompok mencit perlakuan ( III ) dan (IV ) terlihat kerusakan glomerulus semakin meningkat berupa lisisnya sel-sel lapis parietal dan viseral yang mangakibatkan terjadinya atropi dan pelebaran ruang antar Bowman. Kerusakan organ ginjal tampak jelas meningkat seiring dengan kenaikan dosis zat warna C.I. Food Yellow 4 yang dicekokan.

A study of the effects. of a food color substance, C.I. Food Yellow 4, on clinical symptoms of mice (Mus musculus L.) and their kidneys were conducted in the laboratory. Each of four equal groups of six mice was individually fed with an artificial diet, impregnated with C.I. Food Yellow 4, at doses of 0.00, 5.25, 7.25, and 9.25 g I kg of body wieght on a daily basis.

Clinical symptoms of mice were observed every day before scarifying the mice by using a cervix dislocation technique on 6 th day of the experiment. The results showed that all treated mice underwent diarrhea and their weights fluctuated. Kruskal - Wallis test indicated that there was a significant difference (a = 0.05) of glomerulus damage between control and treated mice.

Histological examinations of kidney tissue of mice treated with 5.25 g of food color substance per kg of body weight showed that there was a slightly damage on glomeruli. Mice treated with 7.25 and 9.25 g 1 kg caused heavy damages in glomeruli. Such as parietal and visceral cells lyses which increased distance between two Bowman capsule walls. The level of kidney damage apparently increased with the increase of doses of C.I. Food Yellow 4 given."

"Penelitian dilakukan untuk mengetahui pengaruh pemberian infus serai wangi (Cymbopogon nardus (L.) Rendle.) terhadap gambaran histologi ginjal mencit (Mus musculus L.) jantan galur DDY. Sebanyak 28 ekor mencit dibagi secara acak dalam 4 kelompok yang terdiri atas satu kelompok kontrol (KK) dan tiga kelompok perlakuan (KP1, KP2, dan KP3). Kelompok kontrol diberi akuades dan kelompok perlakuan diberi infus serai wangi dengan dosis 2%, 4%, dan 8% (b/v). Masing-masing kelompok perlakuan terdiri atas 7 ekor mencit. Pemberian bahan uji dilakukan selama 5 hari berturut-turut secara oral. Mencit dikorbankan 2 jam setelah pemberian infus terakhir. Organ ginjal diamati secara makroskopik dan mikroskopik. Sediaan histologi diwarnai dengan pewarnaan Hematoksilin Eosin (HE) dan diamati dengan menggunakan mikroskop. Hasil uji statistik menunjukkan bahwa pemberian infus serai wangi pada dosis 2% dan 4% (b/v) tidak berpengaruh terhadap rata-rata diameter kapsula Bowman, glomerulus, jarak ruang Bowman, serta berat basah organ ginjal, sedangkan pada dosis 8% (b/v) terlihat pengaruh yang nyata terhadap diameter kapsula Bowman dan glomerulus, namun tidak berpengaruh terhadap jarak ruang Bowman.

This research was designed to study the effect of citronella grass (Cymbopogon nardus (L.) Rendle.) infusion on renal histology of DDY male mice (Mus musculus L.). The animals were randomly devided into four groups, consisted of one control group (KK) and three treatment groups (KP1, KP2, and KP3). Control group were given distilled water and the other groups were given doses of citronella grass infusion 2%, 4%, and 8% (w/v) . Each group consisted of 7 mice. The test materials were administered for 5 consecutive days orally. The mice were sacrified at two hours after the last infusion. Kidneys were observed in macroscopic and microscopic. Histology slides stained with Haematoxyline Eosin (HE) and observed with microscope. Statistic study showed that there was no effect of citronella grass infusion at dose of 2% and 4% (w/v) against the average diameter of Bowman?s capsula, glomeruli, diamater of Bowman?s space, and kidneys weight, but there was a significant effect on the average diameter of Bowman?s capsula and glomeruli at a dose of 8% (w/v)."

"Telah dilakukan penelitian untuk mengetahui pengaruh pemberian senyawa dimer isoeugenol terhadap histologi hati mencit (Mus musculus) jantan galur DDY. Tiga puluh ekor mencit dibagi dalam 6 kelompok, terdiri atas kelompok kontrol normal, kelompok kontrol perlakuan, dan kelompok perlakuan yang diberikan senyawa dimer isoeugenol secara oral dengan dosis 2 mg/kg bb, 4 mg/kg bb, 6 mg/kg bb, dan 8 mg/kg bb. Bahan uji diberikan setiap hari selama 7 hari berturut-turut. Kelompok kontrol perlakuan dan empat kelompok perlakuan diinduksi karbon tetraklorida pada waktu 2 jam setelah pemberian minyak zaitun atau senyawa dimer isoeugenol terakhir. Data persentase derajat kerusakan lobulus hati menunjukkan adanya perbedaan pada tiap kelompok perlakuan. Dosis 6 mg/kg bb diketahui dapat memberikan pengaruh hepatoprotektif terhadap histologi hati mencit. Hasil uji Anava 1-faktor menunjukkan tidak terdapat pengaruh pemberian dimer isoeugenol terhadap berat basah dan diameter vena sentralis hati mencit.

The aim of this study was to find hepatoprotective potency of isoeugenol dimer on liver histology of DDY strain male mice (Mus musculus). Thirty male mice were divided into 6 groups, consisting of normal control group, treatment control group, and four treatment groups. The treatment groups were administered with isoeugenol dimer orally at dose 2 mg/kg bw, 4 mg/kg bw, 6 mg/kg bw, and 8 mg/kg bw for 7 days in daily. Treatment control group and treatment groups were induced by carbon tetrachloride 2 hours after the last administration of olive oil or isoeugenol dimer. Data of the percentage damage degree of liver lobules showed that administration of isoeugenol dimer dose 6 mg/kg bw were given hepatoprotective effect on mice liver histology. Statistical analyisis using 1-factor Anava showed that there were no hepatoprotective effect of isoeugenol dimer on gross weight and central vein diameters of mice liver."
