Avaliação farmacognóstica qualitativa das folhas do vegetal Bambusa textilis

Introduction: Bamboos belong to the family Graminae, Bambusoidae subfamily, represented by about 1,250 species worldwide. Originally employed in construction and power, are currently the subject of investigations related to its therapeutic properties in neoplasms. The main species used for therapeutic purposes based on popular knowledge are: Phyllostachys nigra; Bambusa breiflora; tuldoides Bambusa textilis and Bambusa. The literature on the therapeutic action of bamboo species is scarce, but recent studies report a promising effect in the treatment of cancer and other chronic diseases. Objective: This study aimed to evaluate qualitatively the phytochemical composition of plant extract obtained from the leaves of the bamboo species Bambusa textilis, comparing this composition from vegetable leaves with 18 and 24 months of age. Methodology: After collecting plant leaves with 18 or 24 months, they were identified and submitted to drying and milling. For qualitative analysis of its components were employed methods of macroscopic evaluation (mucilage), method of benzoin (resin), reaction Shinoda (flavonoids), reaction with gelatin solution (tannins), boiling and foaming (saponins) and jobs of reactive Wagner, Bertrand, Dragendorff, Mayer, picric acid and tannic acid (alkaloids) (Biavatti; MILK, 2007). Results: in the youngest leaves were found positive for alkaloids, flavonoids, resins and saponins. In the leaves of the plant with 24 months were found only alkaloids flavonoids and resins. Conclusion: the composition of vegetable substances were found associated with a significant therapeutic potential difference and the phytochemical composition in comparison with plant leaves 18 or 24 months. Additional studies are needed to quantify these components, as well as the clarification of its action in the fight against cancer and chronic diseases.

Pancreatic hemangioma manifesting as variceal gastroesophageal bleeding during pregnancy: case report

There are only 10 reported cases of pancreatic hemangiomas in adults, only one of them causing digestive bleeding. We present a case of variceal bleeding and portal hypertension caused by a pancreatic hemangioma. The patient had 19 year-old and was received at her 16th week of pregnancy. She had massive hematemesis, controlled after variceal band ligation. Her image exams revealed a cystic lesion of 164 cm³ in the pancreas tail and signs of portal hypertension. Two months after, the ultrassonographic exam documented the lesion growth, achieving 200 cm³ at that time. The patient was submitted to distal pancreatectomy, and the histopathological analysis revealed a pancreatic hemangioma of 11 x 9 x 8 cm. Therefore, we report the second case of digestive bleeding caused by a pancreatic hemangioma, which had a well documented growth during the pregnancy. Additionally, we review the previous reports of pancreatic hemangiomas and discuss the hypothesis of hormonal infl uence on the natural history of these tumors.

Contexto: Os hemangiomas infantis são os tumores vasculares benignos mais comuns da infância e representam um desafio em relação ao tratamento.Descrição do caso: Descrevemos o caso de uma criança do sexo masculino, de quatro meses de idade, que apresentava um hemangioma de grande extensão na região cervical direita.Discussão: Apresentamos as diversas formas de tratamento dos hemangiomas da infância, com ênfase no tratamento com betabloqueadores sistêmicos.Conclusões: Apesar de o diagnóstico dos hemangiomas infantis não apresentar complexidade, há várias formas de tratamento, com base na localização, no tamanho e nas complicações possíveis de cada lesão em particular.

Estudo com familiares de pacientes com câncer de mama: abordando conhecimento sobre fatores de risco

Breast cancer (BC) is the most common malignancy in women worldwide, with one million new cases confirmed each year. This study aimed at identifying the knowledge of patients? relatives concerning the risk factors (RF) for BC. It is a descriptive quantitative study carried out in the Chemotherapy Technical Division of a University Hospital in São Paulo state, Brazil, from September to October 2006. Only female (30) relatives were included due to the fact that BC is more frequent in females. The major RF cited were family history for BC 33.3% (10), smoking 16.6% (5), alcoholic-drink consumption 10% (3), animal-fat-rich diet 3.3% (1). Other factors such as not breastfeeding, environmental factors, use of oral contraceptives and hormone-replacement therapy were mentioned by 10% (3) of the relatives. It was concluded that the relatives of patients undergoing chemotherapeutic treatment showed to have little knowledge concerning RF for BC. Hence, it is important to rethink the inclusion of the health education process in the family scenario. This issue reaches far beyond thesimple transmission of information. Healthcare professionals and nurses in particular, must focus on these individuals? social context, values, beliefs and needs.
