1. Antiulcer mechanisms of chloroformic and ethyl acetate phases from aerial parts of Praxelis clematidea (Griseb.) R. M. King &H. Robinson (Asteraceae) / Mecanismos antiulcerogênicos das fases clorofórmica e acetato de etila obtidas das partes aéreas de Praxelis clematidea (Griseb.) R. M. King &H. Robinson (Asteraceae)
Praxelis clematidea (Griseb.) R. M. King &H. Robinson (Asteraceae) is a native herb to South America. The chloroformic phase from aerial parts of P. clematidea (CHCl3P-Pc) has hydroxylated and methoxylated flavones and it has shown gastroprotective activity. The ethyl acetate phase (AcOEtP-Pc) has hydroxylated flavonoids. So the gastroprotective activity of

2. Pharmacology and toxicology of diphenyl diselenide in several biological models
The pharmacology of synthetic organoselenium compounds indicates that they can be used as antioxidants, enzyme inhibitors, neuroprotectors, anti-tumor and anti-infectious agents, and immunomodulators. In this review, we focus on the effects of diphenyl diselenide (DPDS) in various biological model organisms. DPDS possesses antioxidant activity, confirmed in

3. Pharmacognostic and gastroprotective activity of aqueous leaf extract of Celtis iguanaea (Jacq.) Sargent / Caracterização farmacognóstica e atividade gastroprotetora do extrato aquoso das folhas de Celtis Iguanaea (Jacq.) Sargent
Celtis iguanaea (Jacq.) Sargent is a small postage plant belonging to the Ulmaceae family, it has very flexible branches, usually in a crossed and overcoated form armed with spines. The leaves are short-petioled, ovals and have sizes that vary from 5-13 cm long and 3-7 cm wide. The tea obtained through it leaves is popularly used for body pain, rheumatism, c

5. Estudo histomorfomÃtrico da musosa gÃstrica do Marsupial didelphis albiventris, submetido, ou nÃo, Ã ingestÃo de Ãlcool
à de grande importÃncia o estudo da mucosa gÃstrica em vÃrios animais, tendo como finalidade o conhecimento anatÃmico, histolÃgico e funcional deles e como respondem quando hà ingestÃo de drogas, entre elas o Ãlcool (etanol). Para essa finalidade, utilizamos a microscopia de luz para estudar o efeito do etanol na morfologia do estÃmago do Didelphis

6. Correlação entre a desnutrição proteica e o processo de formação e reparação de ulceras gastricas : efeito protetor/curativo do oleo essencial de Croton cajucara Benth (Euphorbiaceae)
It is known that the protein malnutrition can affect metabolism rates in humans, rodents and other animals. It is generally accepted that peptic ulcers are caused by a failure in the balance between gastric aggressive factors and mucosal defensive factors. Thus, the primary aim of this work was to verify the correlation between protein malnutrition and the g

7. Hepatocyte growth factor as a key to modulate anti-ulcer action of prostaglandins in stomach.
Although the clinical efficacy of prostaglandins (PGs), especially on gastric mucosal injuries induced by nonsteroidal antiinflammatory drugs, is widely appreciated, their mechanism of action, apart from acid suppression, is quite unclear. In this study, we have established a primary culture system of human gastric fibroblasts and clearly demonstrated that P

8. Diabetes and insulin-induced stimulation of L-arginine transport and nitric oxide synthesis in rabbit isolated gastric glands.
1. The properties of L-arginine transport have been characterized and correlated with cGMP production (index of nitric oxide (NO)) in whole gastric glands isolated from non-diabetic and alloxan-diabetic rabbits. 2. In non-diabetic and diabetic glands, transport of L-arginine was stereoselective, Na+ and pH independent and inhibited by other cationic amino ac

9. Management of panesophageal cancer by blunt resection without thoracotomy and reconstruction with stomach.
Encouraged by their experience since 1978 with blunt esophagectomy and gastric reconstruction in the management of pharyngolaryngeal malignancy, the authors have extended their use of this technique to the management of thoracic esophageal cancer. A study of 43 blunt esophageal resections is presented; 23 were performed in the management of pharyngolaryngeal

10. Mechanisms of gastric and esophageal perforations during laparoscopic Nissen fundoplication.
OBJECTIVE: The purpose of this study was to determine possible mechanisms of 17 gastric and esophageal perforations that occurred during laparoscopic Nissen fundoplication. METHODS: Specific details of each perforation relating to mechanism of injury, surgeon experience, diagnosis, treatment, and outcome were obtained. For each perforation, an attempt was ma
