Integration and expression of Bluetongue VP2 gene in somatic embryos of peanut through particle bombardment method.

After pre-culture and treatment of osmosis, zygotic embryos of peanut (Arachis hypogaea L.) were transformed via particle bombardment with a plasmid containing a Bluetongue VP2 gene (BTVP2) comprising neutralizing epitopes. Selection for Kanamycin resistant calluses and somatic embryos was initiated at 12th day post-bombardment on medium containing 25 mg/L Kanamycin.

Primary malignant melanoma of the lower lip.

Melanomas in the anatomically complex area of the head and neck impose formidable obstacles to treatment. Mucosal melanomas, for reasons which remain uncertain, are associated with a poorer prognosis. Because no systemic treatment is known to be effective, increased awareness by patients and a high index of suspicion is warranted.

Giant pseudopolyps in granulomatous colitis. Report of a case.

A case of giant localized pseudopolyp causing partial large-bowel obstruction and occurring in granulomatous colitis is reported. This represented the first manifestation of the patient's disease. The role of surgery in certain patients is discussed.

Barrett's esophagus.

Barrett's esophagus remains an interesting but incompletely understood entity. Although most authors contend that it is of acquired origin, evidence is presented to substantiate either an acquired or a congenital origin. The possibility exists that Barrett's esophagus may be acquired in some instances and congenital in others.

Alkaline reflux gastritis. A study in forty postoperative duodenal ulcer patients.

A study to determine the incidence of alkaline reflux gastritis in forty postoperative duodenal ulcer patients has been presented. Since the majority of patients had evidence of gastritis, the precise role that gastritis plays in the production of symptoms is discussed but needs further clarification. It is suggested that the presence of gastritis may only represent an incidental or associated finding in many patients presenting with symptoms presumably characteristics of alkaline reflux gastritis.
