The present study was carried out for the evaluation of antioxidant activities of clover (Syzygium aromatium L.) and cinnamon (Cinnamomum verum L.). The research work was carried out at the Institute of Molecular Biology, University of Lahore. The samples of clovers and cinnamon were collected from Lahore and were crushed to prepared sample in n-hexan, and ethanol extracts for evaluation of antioxidant activities. The highest antioxidant activities of ethanol extract from cinnamon indicated that the cinnamon may be used as an active ingredient to control stress conditions of cells for stress avoidance. The alkaloids, coumarins, saponins, flavonoids, tannins, sterols, quinons, triterpenoids, anthocyans, leucoanthocyans and terpenoids were tested for both ethanol and n-hexan extracts which indicated that most of the components were found present in both of the plant species, which revealed that these herbal plant seeds may be used as potential medicinal plants.

Indian tribes constitute around 8.3% of the total population. The health problems of tribal communities are influenced by the interaction of various socioeconomic and political factors. An attempt is made to document the traditional knowledge of the Kani tribes in the floristically rich Peringamala panchayath of Thiruvananthapuram district. The investigation revealed that the Kani tribes were using 127 species of ethnomedicinal plants, belonging to 57 families. The most cited family was Fabaceae and leaves were the most frequently used plant parts for the treatment of various diseases. Some medicinal plants used by Kani tribes which are included in the list of rare and endangered categories, such as Aristolochia tagala, Holostemma adakodien, Entada scandens, Anaphyllum beddomeii, decalepsis arayalpathra which are vanishing from the tribal settlement areas. So special attention should be given to cultivate and conserve these rare medicinal plants by making them available for mass cultivation, either through conventional methods or other non-conventional methods like micropropagation. The study showed that the Kani tribes have good knowledge about medicinal plants that have been passed orally from generation to generation. Current healers may be the final generation of Kani tribal healers. Due to rapid socio-economic and cultural changes, there is a possibility of losing the treasure of tribal knowledge in near future. The wealth of this tribal knowledge would lead to a greater potential for the Indian system of medicine towards new drug discovery and development.

The visualization of organic macromolecules such as proteins, nucleic acids, viruses and virus components has reached its high degree of effectiveness owing to refinements and reliability of instruments and to the invention of methods for enhancing the structure of these materials within the electron image. The latter techniques have been most important because what can be seen depends upon the molecular and atomic character of the object as modified which is rarely evident in the pristine material. Structure may thus be displayed by the arts of positive and negative staining, shadow casting, replication and other techniques. Enhancement of contrast, which delineates bounds of isolated macromolecules has been effected progressively over the years as illustrated in Figs. 1, 2, 3 and 4 by these methods. We now look to the future wondering what other visions are waiting to be seen. The instrument designers will need to exact from the arts of fabrication the performance that theory has prescribed as well as methods for phase and interference contrast with explorations of the potentialities of very high and very low voltages. Chemistry must play an increasingly important part in future progress by providing specific stain molecules of high visibility, substrates of vanishing “noise” level and means for preservation of molecular structures that usually exist in a solvated condition.

Spin-polarized scanning electron microscopy (spin SEM), where the secondary electron spin polarization is used as the image signal, is a novel technique for magnetic domain observation. Since its first development by Koike and Hayakawa in 1984, several laboratories have extensively studied this technique and have greatly improved its capability for data extraction and its range of applications. This paper reviews the progress over the last few years.Almost all the high expectations initially held for spin SEM have been realized. A spatial resolution of several hundreds angstroms has been attained, which is nearly one order of magnitude higher than that of conventional methods for thick samples. Quantitative analysis of magnetization direction has been performed more easily than with conventional methods. Domain observation of the surface of three-dimensional samples has been confirmed to be possible. One of the drawbacks, a long image acquisition time, has been eased by combining highspeed image-signal processing with high speed scanning, although at the cost of image quality. By using spin SEM, the magnetic structure of a 180 degrees surface Neel wall, magnetic thin films, multilayered films, magnetic discs, etc., have been investigated.
