Misoprostol - A Wonder Drug

Misoprostol is a synthetic analogue of natural prostaglandin E1. It has a very convenient and flexible drug dosing, can be administered orally, sublingually, buccally, rectally and by vaginal route. Misoprostol is useful for elective early medical abortion, cervical ripening in surgical abortion as well as in gynecological D & C, mid trimester abortion, cervical ripening and induction of labour in live or dead fetus as well as in prevention and treatment of PPH. Key words: Misoprostol; medical abortion; induction of labour; postpartum hemorrhage.DOI: http://dx.doi.org/10.3329/bjms.v10i4.9490BJMS 2011; 10 (4): 221-225

Terson's syndrome

Terson's syndrome is rarely encountered in ophthalmic practice. The ophthalmologists should be acquainted with the clinical features and methods of diagnosis of this syndrome. Here we report a middleaged lady with altered sensorium, visual impairment and headache who was diagnosed as having Terson's syndrome after fundoscopy and spinal tap. It was managed conservatively. Key words: vitreous hemorrhage; subarachnoid hemorrhage DOI: 10.3126/nepjoph.v1i1.3678 Nep J Oph 2009;1(1):77-79

The Determination of Thermal Diffusivities of Thermal Energy Storage Materials, Part I: Solids up to Melting Point

This paper describes a method for the determination of thermal diffusivities which has been developed specifically for substances which are poor conductors and which have high melting points. Materials which are useful for thermal energy storage fall into this category. The method has several unique features. The basic principle involved consists of raising the surface temperature of a solid specimen at a uniform rate. After the initial transients have died out, the diffusivity can be determined from temperature measurements alone. The advantages of the method are: (a) Heat flux measurements are not needed; (b) materials can be tested right up to the melting point, since the specimens can be encapsulated and softening can be tolerated; (c) large temperature ranges can be tested quickly; (d) precision and accuracy are good. The method has been extended to the liquid range, and results will be published as Part II. Results of measurements are reported for alumina and lithium fluoride. The results for alumina (Lucalox) check results reported previously. The results on LiF differ from published results. Data on other substances are still being produced and results will be published at a later date.
