Abstract. Euphorbia hirta, commonly known as asthma weed, is a popular folk remedy for the treatment of various ailments. Recent studies have indicated that plant has potent antioxidant properties. As part of an ongoing programme to validate the use of some reputed herbs in Indian traditional medicines, the present study was aimed to evaluate the antidiabetic and antioxidant potentials of E. hirta leaves in streptozotocin-induced experimental diabetes in rats. Oral administration of E. hirta leaves extract (300 mg/kg b.w./rat/day) for a period of 30 days indicated the antidiabetic nature of the leaves extract. Determination of the lipid peroxides, hydroperoxides, and both enzymatic and nonenzymatic antioxidants evidenced the antioxidant potential of the leaves extract. Assay of enzymes such as serum aspartate transaminase (AST), serum alanine transaminase (ALT) and serum alkaline phosphatase (ALP) revealed the non-toxic nature of E. hirta leaves. The hypoglycemic activity of the leaves extract was comparable with gliclazide, a standard reference drug.

The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

Background: There has been growing public awareness regarding the ethical conduct of medical practitioners, and complaints against physicians appear to be escalating. After completing their studies, healthcare professionals are expected to know ethical principles and apply them in their clinical practice. Hence, this study was conducted to assess the knowledge and attitude of medical ethics among final year medical students.Methods: Cross sectional study was conducted among final year Medical students in a private medical college. After obtaining permission from Institutional ethics committee, the purpose of the study and nature of information which has to be furnished from the students was explained to them. Willingness to participate in the study was obtained from participants using written consent form. Data was collected among 135 medical students using pre tested self-administered questionnaire. The respondents were asked to grade their responses on a 3 point Likert scale.Results: Study results showed majority 87% of students felt patient wishes must always be adhered to. In contrast 65% of students felt doctors must do what is best irrespective of patient’s opinion. About 64.7% of them disagreed consent is required only in case of operations and not for tests and medications. Nearly half (47%) of the students were of opinion privacy of the patient must not be ignored for benefit of larger group.Conclusions: The fact that many respondents had neutral opinion to some questions may indicate their lack of awareness or knowledge in that area and their inability to decide. Hence there should be sufficient training classes, workshops, conferences to stress the importance of ethical practice.
