Coriander (Coriandrum sativum L.) is grown as a spice crop all over the world. The seeds have been used to treat indigestion, diabetes, rheumatism and pain in the joints. In the present study, an ethanol extract of the seeds was investigated for effects on insulin release from the pancreatic beta cells in streptozotocin-induced diabetic rats. Blood samples were drawn from the retro-orbital sinus before and 1.5, 3 and 5 h after administration of the seed extract. Serum glucose levels were determined by the glucose oxidase method. To determine the insulin releasing activity, after extract treatment the animals were anaesthetized by diethyl ether, the pancreas was excised, fixed in 10% formaldehyde and embedded in paraffin for sectioning. Pancreatic sections of 5 microm were processed for examination of insulin-releasing activity using an immunocytochemistry kit. The results showed that administration of the ethanol extract (200 and 250 mg/kg, i.p.) exhibited a significant reduction in serum glucose. Administration of streptozotocin decreased the number of beta cells with insulin secretory activity in comparison with intact rats, but treatment with the coriander seed extract (200 mg/kg) increased significantly the activity of the beta cells in comparison with the diabetic control rats. The extract decreased serum glucose in streptozotocin-induced diabetic rats and increased insulin release from the beta cells of the pancreas.

Backgroundc-MET is an oncogene protein that plays important role in gastric carcinogenesis and has been introduced as a prognostic marker and potential therapeutic target. The aim of this study was to evaluate the frequency of c-MET overexpression and its relationship with clinicopathological variables in gastric cancer of Iranian population using tissue microarray.MethodsIn a cross sectional study, representative paraffin blocks of 130 patients with gastric carcinoma treated by curative gastrectomy during a 2 years period of 2008–2009 in two university hospitals in Tehran-Iran were collected in tissue microarray and c-MET expression was studied by immunohistochemical staining.ResultsFinally 124 cases were evaluated, constituted of 99 male and 25 female with the average age of 61.5 years. In 71% (88/124) of tumors, c-MET high expression was found. c-MET high expression was more associated with intestinal than diffuse tumor type (P = 0.04), deeper tumor invasion, pT3 and pT4 versus pT1 and pT2 (P = 0.014), neural invasion (P = 0.002) and advanced TNM staging, stage 3 and 4 versus stage 1 and2 (P = 0.044). The c-MET high expression was not associated with age, sex, tumor location, differentiation grade and distant metastasis, but relative associations with lymph node metastasis (P = 0.065) and vascular invasion (P = 0.078) were observed.Conclusionsc-MET oncogene protein was frequently overexpressed in Iranian gastric carcinomas and it was related to clinicopathological characteristics such as tumor type, depth of invasion, neural invasion and TNM staging. It can also support the idea that c-MET is a potential marker for target therapy in Iranian gastric cancer.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/9744598757151429

Xanthogranulomatous inflammation, as a type of chronic granulomatous inflammation, typically occurs in the gall bladder and kidneys. In this paper, we present a 56-year-old man with Xanthogranulomatous cystitis mimicking bladder malignancy. He was referred to our clinic with the chief complaint of a one-year history of urgency and frequency. CT scan showed a solid lesion in the bladder. The patient underwent complete transurethral resection of the bladder tumor. Microscopic histopathology revealed xanthogranulomatous cystitis. The patient received a course of antibiotic therapy. Follow-up Cystourethroscopy showed normal bladder.

Pure small cell carcinoma of the prostate (SCPCa) is a very rare condition usually with poor survival after diagnosis. It seems to show different clinical features compared to other prostate cancer subtypes, specifically adenocarcinoma. Here, we present a 74-year-old man early diagnosed with SCPCa treated with a cisplatine and etoposide regimen. There was no metastasis found in imaging studies and bone scan. The patient mostly complained of obstructive symptoms which were relieved after resection. Interestingly, our patient experienced a disease free condition after chemotherapy and no further progression was found. This could implicate the critical role of early diagnosis in the treatment of SCPCa despite its aggressive nature.
