Small Intestinal Biopsy: Diagnostic and Research Value

Small Intestinal Biopsy Specimens

The effect of 5-hydroxytryptamine (5-HT) on the crypt cell production rate in normal human duodenal mucosa cultured in vitro was studied using a stathmokinetic technique with crypt microdissection. The addition of 5-HT (2 mg/ml) to the culture medium significantly increased the crypt cell production rate (p < 000 1), suggesting that this amine may have a trophic effect on crypt cells in vitro. ...

Evaluation of Diagnostic Value of CT Scan and MRI in Brain Tumors and Comparison with Biopsy

Abstract Background Cerebral neoplasm arises from brain, spinal cord and meningeal cells. Not only malignant cerebral neoplasm also benign tumor could lead to death due to mass effect on vital structures. Access to these tumors is difficult, and MRI and CT scan could be helpful in determining anatomical location of tumors and distinction of malignant from benign. Objective For better and ea...

THE DIAGNOSTIC VALUE OF FINE NEEDLE ASPIRATION BIOPSY OF HEAD AND NECK MASSES

In an attempt to determine the diagnostic value of FNA biopsy of head and neck masses, we reviewed FNAs performed on target lesions of the head and neck in1 59 patients who subsequently underwent surgery in Khalili hospital dur-. ing a 55 month period. Results ofFNAs were compared with postsurgical histologic diagnoses. These 159 cases were broken down into four categories: thyroid masses ...

The diagnostic value of liver biopsy

BACKGROUND Since the introduction of molecular diagnostic tools such as markers for hepatitis C and different autoimmune diseases, liver biopsy is thought to be useful mainly for staging but not for diagnostic purposes. The aim was to review the liver biopsies for 5 years after introduction of testing for hepatitis C, in order to evaluate what diagnostic insights - if any - remain after serolog...
