Gastric ulceration was recognized as an occasional complication of vagotomy soon after Dragstedt championed the operation for the treatment of duodenal ulceration (Dragstedt and Owens, 1943). Gastric atony and antral stasis were to be expected after vagotomy without adequate drainage of the gastric contents and it was perhaps not surprising that a number of patients should have developed lesser...

Six types of weight changes that occur when food is cooked by different methods are described. For five of these types, true retentions of nutrients (defined as calculations based on nutrient content of known weights of food before and after cooking) were compared with apparent retentions (defined as calculations based on nutrient content of moisture-free raw and cooked foods). Comparisons incl...

this .study is a retrospective study of 10 patients with early gastric cancer, (6 from imam khomeini hospital between 1985 to 1994 and 4 from private office) . from the standpoint of clinical and pathological views, treatment modalities and prognosis. in imam khomcni hospital early gastric cancer comprises near l'7t, (6/560) of all gastric cancers, which may he due to late reference, lack of sc...

The dome-shaped radiopaque shadows frequently seen on the floor of the maxillary sinus, and sometimes inaccurately referred to as antral mucoceles, appear to represent focal accumulation of inflammatory exudate that lifts the epithelial lining of the sinus and the periosteum away from the underlying bone to form the characteristically shaped structures. Their histologic appearance is therefore ...

In this micro-scale method for liquid-chromatographic measurement of cimetidine in 250-microL volumes of plasma or gastric fluid, a combination of organic- and aqueous-phase extractions, and protonation of the internal standard and cimetidine, enabled us to detect 2.0 ng of cimetidine on the column. We also used a radial compression module, which reduced the retention times for cimetidine and t...

We describe the usefulness of thallium-201 SPECT in a patient with neoplastic meningitis (NM) from gastric carcinoma. Thallium-201 SPECT is of value for the diagnosis of cancer; retention of thallium-201 on delayed images strongly suggests malignancy. NM is a lethal, major neurologic complication of cancer. The standard for the diagnosis of NM is cytologic confirmation of malignant cells in CSF...

The patient was a 37-year-old female teacher with hyperemesis diabeticorum and juvenile Type-I diabetes. At the age of 29 years, nausea and vomiting developed and secured at nearly weekly intervals. She was started on clotiazepam (15 mg/day). The vomiting was cured and psychological improvement was evident; her anxiety about diabetes was markedly reduced. An X-ray examination after the administ...

Gastric emptying is a complex process and makes in vivo performance of the drug delivery systems uncertain. In order to avoid this variability, efforts have been made to increase the retention time of the drug-delivery systems for more than 12 hours. The floating or hydrodynamically controlled drug delivery systems are useful in such application. From the formulation and technological point of ...
