Background
Cholestasis is a pathophysiological condition, significantly reducing spermatozoa production. MiR-34c is highly expressed in adult male testicles and controls different stages of spermatogenesis.
ObjectivesHere, we aimed to investigate miR-34c expression in the testes of rat models of cholestasis. The expressions of THY-1, FGF-2, and CASP-3 genes, that are targeted by mirR-34c were also investigated.
MethodsCholestasis was induced in six adult rats via bile duct ligation. Four weeks after cholestasis induction, sera and testicular tissues were collected for further examinations. The levels of liver enzymes were measured using the ELISA. The structure of the testes was evaluated by histological examination. Total RNA was extracted from testes using a special kit and converted to cDNA. The expressions of miR-34c-5p, THY-1, FGF-2, and CASP-3 genes were determined by Real-Time PCR.
ResultsThe serum levels of ALP, AST, and ALT were significantly elevated in the rat models of cholestasis (P < 0.001). Real-Time PCR revealed that the expressions of miR-34c-5p, THY-1, and FGF-2 genes decreased while CASP-3 gene was upregulated in the testes of cholestatic animals (all differences were significant at P < 0.05).
ConclusionsOur study indicated that cholestasis was associated with reduced expression of miR-34c and altered expression of its target genes in the testis. Our results highlight the potential effects of cholestasis, a hepatobiliary disease, on testicular tissue function and male fertility.

مجله دانشکده پزشکی دانشگاه علوم پزشکی مشهد، سال شصت و سوم شماره 2 (پیاپی 170، خرداد و تیر 1399)، صص 2300 -2308مقدمه
مورفین به عنوان یک آگونیست کامل اپیوییدها به صورت اولیه فعالیت خود را روی رسپتورهای مغز اعمال می کند. عارضه اولیه سوء مصرف آن، افت تنفسی از طریق دپرس کردن مستقیم سیستم عصبی مرکزی بوده و در نهایت می تواند باعث آپنه یا ایست کامل تنفسی شود. دوز سمی مورفین باعث سرکوب سیستم عصبی مرکزیوکما می شود.جهت آنالیز داروهای مورد سوء مصرف غالبا از نمونه هایی مانند خون، کبد و ادرار استفاده می شود.
روش کاردر این مطالعه، به طور همزمان دو نمونه صفراء و ادرار در 635 نمونه مجهول آزمایش تشخیص مورفین و کدیین که جهت بررسی های سم شناسی قانونی در سال های 1396 و 1397 به پزشکی قانونی ارجاع شده بودند، با استفاده از روش کروماتوگرافی لایه نازک مقایسه گردیدند.
نتایجنتایج به دست آمده نشان دادند که سطوح مورفین در صفرا چندین برابر بیشتر از قسمت های دیگر می باشد.در مواردی که یک دارو یا متابولیت های آن همچنانکه در خون وسایر نمونه ها قابل تشخیص نباشد، در صفرا تشخیص داده می شوند.
نتیجه گیری:
با نظر به نتایج به دست آمده می توان نتیجه گرفت که نمونه صفرا به عنوان یک مکمل در کنار سایر نمونه ها در تشخیص مورفین، متادون و کدیین قابل استفاده و استنادمی باشد.

Initial symptoms of morphine abuse are respiratory depression through direct central nervous system depression and can ultimately lead to apnea or complete respiratory arrest. Toxic dose of morphine suppresses the central nervous system and can cause coma. For the analysis of drugs abuse, often examples such as blood, liver, bile and urine are used.
Materials and MethodsIn this study, urine and bile samples of 635 unknown samples were tested for morphine and codeine using thin layer chromatography and to biologic samples were compared.
ResultsMeanwhile, aside from the negative examples and statistical analysis was performed between positive samples. The results showed that morphine levels in bile are many times more than in the other samples. In cases that a drug or its metabolites in the blood and other samples cannot be detected, it can be detected in the bile.
ConclusionConsidering the results of this study, it can be concluded that bile samples as a supplement along with other samples such as urine can be used in detection and documentation of morphine and codeine.

A rare case of ascaris coming out through the anterior abdominal wall is reported here. A 40‑year‑old female had undergone dilatation and curettage by a quack. On the second day she presented with presented with features of peritonitis. She was explored. Resection anastomosis of the ileum was done for multiple perforations of the ileum. Patient developed a fistula in the anterior abdominal wall which was draining bile‑colored fluid. On the 12th postoperative day a 10‑cm‑long worm was seen coming out through the fistulous tract which was found to be Ascaris lumbricoids. Ascaris lumbricoids can lead to many complications ranging from worm colic to intestinal obstruction, volvulus, peritonitis, pancreatitis, cholangiohepatitis, liver abscess and many more. Worm has been reported to come out through mouth, nostrils, abdominal drains, T‑tubes etc. But ascaris coming out through the anterior abdominal wall is very rare hence reported here.Keywords: Ascaris, bile, perforation

Comparing Bile and Urine Samples as Morphine Detectors in CorpsesInternational Journal of Medical Toxicology and Forensic Medicine, Volume:1 Issue: 1, Summer 2011, PP 12 -16IntroductionThe present study aims to compare bile and urine samples of a corpse for detection of morphine.MethodsIn this cross-sectional study, forensic examination of the bodies placed 59 of the 366 referred corpses at the high suspicion of opioid overdose. Urine and bile samples of the bodies were analyzed for morphine using thin layer chromatography.ResultsAll samples were taken from male bodies. There were no urine samples in four corpses (7%) and two urine samples (3%) produced negative results. In the remaining 53 cases, 14(24%) turned out 1+, 29(49%) turned out 2+, 8(14%) bodies turned out 3+ and 2(3%) corpses produced 4+. On the other hand, all bile samples produced positive results, in which 3(5%) turned out 1+, 20(34%) turned out 2+, 22(37%) bodies turned out 3+ and 14(24%) corpses produced 4+. The Spearman coefficient for positive urine or bile samples was 0.377(P = 0.005).ConclusionThe results of the present study show that the concentration of detected morphine in bile is greater than that of urine. Therefore, a bile sample can contribute to the detection of opioid in the corpses, especially when urine samples are not available or are negative.Keywords: Opioid, Morphine, Urine, Bile, Corpse

BackgroundBile gastritis (gastropathy) is a kind of gastritis which is caused by reflux of bile contents through duodenum on stomach. It can occur spontaneously without any former gastric surgeries which affect sphincter of pylorus. The positive impact of some certain drugs such as prokinetic agents e.g. metoclopramide, Proton-pump inhibitors (PPIs), cholestyramine and sucralfate in treating bile gastritis has been confirmed. This study has been conducted in order to analyze the effect of ursodeoxycholic acid (UDCA), which is a harmless drug, on patients with the bile gastritis.Materials And MethodsIn this clinical trial, all patients with dyspepsia who were qualified to undertake endoscopy were enrolled and then 60 patients with bile gastritis were selected for the study. The patients were divided into two groups; a group was treated by UDCA, omeprazole and sucralfate and another one was treated with placebo, omeprazole and sucralfate for two weeks. Finally, at the end of the third week of treatment patients were examined.ResultsA total of sixty 19-70 year-old patients (Mean: 46 years old) included in this study. At the end of the study, there was not found any meaningful difference between the two groups in terms of pain intensity, heartburn intensity, severity of bloating, vomiting and early satiety; however, each group independently showed improvement of the mentioned indices after termination of the treatment (p=0.0005).ConclusionAdding UDCA to the standard treatment (sucralfate) is not clinically effective in curing the bile gastritis.Keywords: UDCA, Bile, Gastropathy, Gastritis

زمینهتحقیقات اخیر حاکی از احتمال وجود یک ارتباط بین عفونت ناشی از بعضی از اعضاء هلیکوباکتر و تشکیل سنگ کیسه صفرا میباشند. هدف از این تحقیق تشخیص باکتری هلیکوباکتر در سنگهای کیسه صفرای بیماران مبتلا به بیماری های دستگاه صفراوی بوده است.
مواد و روشها: سنگ های صفراوی و نمونه های مایع صفرای 33 بیمار با تست های اورهآز سریع، کشت و واکنش زنجیره ای پلیمراز چندتایی (Multiplex-PCR) که بر اساس دو ژن 16S rRNA و ایزوسیتراتدهیدروژناز برای تشخیص به ترتیب جنس هلیکوباکتر و گونه هلیکوباکترپیلوری طراحی شد، مورد بررسی قرار گرفتند. این روشPCR همچنین بر روی نمونه های مایع صفرای 40 کیسه صفرای اتوپسی شده و نرمال از نظر پاتولوژی، بعنوان گروه شاهد انجام گرفت.یافته هادر 1/18 درصد از سنگها و 1/12 درصد از نمونه های مایع صفرا، ژنوم هلیکوباکترپیلوری با روش PCR تشخیص داده شد. تست های اورهآز سریع و کشت برای کلیه نمونه ها منفی بود. در گروه کنترل با روش PCRژنوم هلیکوباکتر شناسایی نشد.
نتیجه گیری: در مجموع در این مطالعه DNA هلیکوباکترپیلوری در نمونه های سنگ کیسه صفرای بیماران مشاهده شد، اما در مورد زنده بودن این ارگانیسم در این نمونه ها اطمینان حاصل نشد. برای آشکار نمودن نقش کلینیکی گونه های هلیکوباکتر در بیماری های کیسه صفرا، مطالعات گستردهتر توصیه میشود.

The aim of this study was identification of Helicobacter members in gallstones from patients with biliary diseases.MethodsGallstones and bile samples from 33 patients were subjected to rapid urease test, culture and Multiplex-PCR using primers based on 16s rRNA and isocitrate dehydrogenase genes to identify Helicobacter genus and H. pylori species genes, respectively. This PCR was also done on bile samples from 40 autopsied gallbladders with normal pathology (as a control group).ResultsIn 18.1% of stones and 12.1% of bile samples, H. pylori DNA was detected using PCR. Rapid urease and cultures tests were negative for all samples. The genome of H. pylori was not detected in control group using PCR.ConclusionH. pylori DNA was detected in gallstone, however, we are not sure of H. pylori viability in these samples. To clarify the clinical role of Helicobacter in gallbladder diseases, more investigations are needed to ascertain whether this microorganism is innocent bystander or active participant in gallstone formation.Keywords: helicobacter pylori, bile, gallstone, Multiplex, PCR -
Spillage of scoleces is a major problem in surgery of hydatid cysts, because each of them may develop into a new cyst if it settles on a suitable site such as the peritoneum. Many surgeons believe that scoleces in ruptured hydatid cysts of the liver containing bile are not able to develop new cysts, because bile kills thein. In order to prove this idea, the viability of scoleces in such cysts was assessed and the effect of bile on live scoleces of unruptured liver cysts of sheep and human beings was also assessed in the laboratory. It was concluded that bile is not scolecidal, and an unfavorable environment is the cause of death bf the •scoleces. Scoleces in ruptured cysts may be alive and able to develop a new cyst. Therefore the surgeon should use all necessary precautions to prevent spillage.
