"Non-steroid anti-inflammatory drugs (NSAID) can cause gastropathy and gastric mucosa, especially the mucous may play an important prevention role. This cross-sectional, single group study was conducted to evaluated the difference of mucous thickness in antrum or corpus mucosa and the correlation of gastric mucous thickness to gastropathy. Patients who received NSAID from the rheumatology clinic were studied. Healthy subjects of 14 - 65 years old who never received NSAID were included as normal controls. Piroxicam 20 mg daily was given to the patients for 7 days, then gastroscopy and gastric mucosa biopsy with frozen section were performed. Specimens were stained with haematoxyline eosin and thickness of the mucous layer was measured using ocular micrometer. Thirty-two out of 70 patients participated in the study. All cases had hyperemia on gastroscopy with erosions and ulcer in 32 and 9 cases, respectively. The mean thickness of mucosa in distal antrum, proximal antrum and corpus was 28.5 ± 9, 37.4 ± 13.1 and 43.3 ± 13.1 microns, respectively. There was significant relationship between gastric mucosa mucous thickness with gastroscopic findings. In conclusion, this study confirmed that thickness of gastric mucosa mucous has an important role in preventing NSAID gastropathy and dyspeptic complaints in this kind of patients does not suggest abnormalities of gastric mucosa."

"Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pegagan pada ketahanan mukosa Iambung (gastroprotektif) tikus yang mengalami stres immobilisasi baik secara makroskopik dengan parameter luas ulkus dan skor perdarahan dan secara mikroskopik parameter edema, infiltrasi leukosit, dan nekrosis jaringan Iambung tikus.Penelitian ini merupakan penelitian eksperimental in vivo,dilakukan dengan 5 kelompok perlakuan dengan 6 ulangan. Kelompok I adalah kelompok kontrol diet normal, kelompok Il kelompok kontrol diet normal dicampur pegagan 1 gr/kg bb hari, kelompok Ill adalah kelompok kontrol tikus yang mengalami stres immobilisasi tanpapemberian pegagan sebelumnya, Kelompok IV dan V adalah kelompok yang sebelumnya mendapat diet pegagan selama 3 hari sebelum stres immobilisasi dengan konsentrasi pegagan 0,5 gr/kg bb hari dan 1,0 gr/kg bb hari.Hasil pengamatan makroskopis menunjukkan bahwa Iuas ulkus dan skoring, perdarahan kelompok I, Il, III, terdapat perbedaan yang bemakna dan dibuktikan secara mikroskopik untuk parameter edema, infilrasi leukosit dan nekrosis juga rerdapat perbedaan yang bermakna. Sedangkan untuk kelompok III, IV dan V secara makroskopik Iuas ulkusdan skoring perdarahan tidak ada perbedaan yang bermakna dan dibuktikan dengan pengamatan parameter inflamasi, (edema, infiltrasi leukosit dan nekrosis) juga tidak terdapat perbedaan yang bermakna.Stres immobilisasi dapat menyebabkan ulkus lambung, sedangkan padapenelitian ini terlihat bahwa efek gastroprotektif pegagan pada kondisi stres immobilisasi menunjukkan tidak ada perbedaan yang bermakna walaupun ada penurunan dari parameter luas ulkus, skoring perdarahan dan parameter proses inflamasi dibandingkan dengan kontrol."

"Background: Thin study aimed to investigate gastric mucosa mucous layer thickness in portal hypertensive gastropathy (PHG) compare to normal mucosa in functional dyspepsia and its correlation with several variables such as child class, severity of esophageal varices and gastropathy.

Materials and Methods: Biopsy specimens were taken from the antrum and corpus from both group of patients with PHG and functional dyspepsia. The specimen was given cryometric for frozen section. Tissue were sliced by sagital section II urn, placed in object glass, fixed and stained to evaluate mucous thickness and giemsa stained to observe Helicobacter pylori. Measurement of mucous thickness was done upward muscularis mucosa started from upper epithelial layer from faveale tip until outer mucous layer on 15 points which were marked randomly and calculate the mean value by micrometer (/jm).

Results: Mean value of antral mucous thickness in PHG was 13.30 ± 6.5 fim, while in the functional dyspepsia it was 25.59 ± 5.66 /an. Statistical analysis for both kinds of mucous thickness was p<0.001. Mean corpus mucous thickness in PHG was 10.6 ± 6.81 /jm, while mucous thickness in dyspepsia was 32.54 ± 6.51 fjm. Statistical analysis revealed p<0.001. This result showed significant difference of mucous thickness of antrum and corpus statistically between PHG and dyspepsia as control group.

Conclusion: The study had proven the presence of decreased gastric mucosa mucous layer thickness in corpus and antrum in PHG. Thus, therapeutic approach to increase mucous thickness must be considered in patients with PHG."

"Latar belakang: MRCP merupakan teknik pencitraan tidak invasif untuk mengevaluasi anatomi dan mendeteksi kelainan sistem bilier. Cairan di saluran bilier akan memperlihatkan sinyal yang tinggi pada MRCP. Salah satu keterbatasan pemeriksaan MRCP ialah cairan di saluran gastrointestinal juga memberikan sinyal tinggi yang dapat mengganggu evaluasi saluran bilier. Sari buah nanas dapat menjadi kontras oral negatif untuk menurunkan sinyal di gastrointestinal. Belum terdapat penelitian penggunaan sari buah nanas pada pemeriksaan MRCP di Indonesia dan belum terdapat penelitian yang menilai visualisasi cabang-cabang duktus intrahepatikus setelah pemberian sari buah nanas. Tujuan: Mengukur perbedaan SNR gaster dan duodenum serta perubahan tingkat visualisasi cabang-cabang duktus bilier intrahepatikus sesudah pemberian sari buah nanas pada pemeriksaan MRCP. Metode: Dilakukan pemeriksaan MRCP sebelum dan sesudah pemberian sari buah nanas pada subjek penelitian. Mengukur perbedaan rerata SNR gaster dan duodenum serta mengukur perubahan tingkat visualisasi cabang-cabang duktus bilier intrahepatikus sebelum dan sesudah pemberian sari buah nanas. Perbedaan rerata SNR gaster dan duodenum dianalisis menggunakan uji Wilcoxon dan perubahan tingkat visualisasi dianalisis dengan uji McNemar untuk menilai diskordans. Hasil: Didapatkan 25 subjek penelitian yang menjalani pemeriksaan MRCP sebelum dan sesudah pemberian sari buah nanas. Terdapat penurunan bermakna SNR gaster dan duodenum setelah pemberian sari buah nanas, 127,1 (18,7-1194,6) menjadi 42.2 (4,2-377,1) untuk gaster dan 64,1 (3,8-613.4) menjadi 44,6 (6,5-310,3) untuk duodenum (p < 0,05). Terdapat perubahan bermakna tingkat visualisasi duktus bilier intrahepatikus (p < 0,05, diskordans >50%) dengan peningkatan tingkat visualisasi duktus intrahepatikus kanan segmen anterior pada 66% pengamatan, duktus intrahepatikus kanan segmen posterior pada 58% pengamatan, dan 70% pengamatan untuk duktus intrahepatikus kiri. Simpulan: Pemberian sari buah nanas dapat menurunkan sinyal gaster dan duodenum pada pemeriksaan MRCP dan mempengaruhi tingkat visualisasi cabang-cabang duktus bilier intrahepatikus.

Background: MRCP is a non-invasive imaging technique for evaluating anatomy and detecting abnormalities of the biliary system. Fluid in biliary tract will show high signal on MRCP. One of the limitations of MRCP is high signal in gastrointestinal fluid which can interfere biliary tract evaluation. Pineapple juice as negative oral contrast can reduce signal in gastrointestinal tract. There have been no studies on the use of pineapple juice for MRCP in Indonesia, and no studies assessed the visualization of intrahepatic ductal branches after administration of pineapple juice. Objective: Measuring difference in gastric and duodenal SNR and changes of visualization of intrahepatic biliary ductal branches after administration of pineapple juice on MRCP. Methods: MRCP before and after administration of pineapple juice were performed on subjects. Gastric and duodenal SNR mean difference were measured, and analysis were done with Wilcoxon test. Level of visualization of intrahepatic biliary ductal branches were also measured and analysed with McNemar test for discordances. Results: There were 25 subjects underwent MRCP. Gastric and duodenal SNR were statistically decreased after administration of pineapple juice, 127.1 (18.7-1194.6) vs 42.2 (4.2-377.1) and 64.1 (3.8-613.4) vs 44.6 (6.5-310.3) respectively (p <0.05). Statistically significant difference was observed in visualization of intrahepatic ductal branches (p<0,05), discordance >50%) with increase in visualization of right duct anterior segment in 66% observation, right duct posterior segment in 58% observation, and 70% observation in left intrahepatic bile duct. Conclusion: Use of pineapple juice as negative oral contrast significantly reduce gastric and duodenal signal in MRCP also affect visualization of the intrahepatic biliary duct branches.
