Phytochemical and antimicrobial activity of methanol extract of Albizia ferruginea (Guill and Perr) which belongs to the family of Fabaceae were studied. Phytochemical studies on the plant leaves showed that they contained alkaloids, tannins, flavonoids, steroids, saponins, cardiac glycoside and carbohydrate. Methanol extract of Albizia ferruginea showed growth inhibitory effects of varying degrees on S. feacalis, S. typhi, S. paratyphi, Shigella dysentriae and Klebsiella pneumonia but was not active on Streptococcus pyogenes and Pseudomonas aeruginosa. The minimum inhibitory concentration (MIC) of the extract was determined for the organisms whose growths were inhibited. The extract had MIC of 3.25mg/ml for S. feacalis, S. paratyphi, S. dysentriae and K. pneumoniae respectively. The antimicrobial studies of the extracts really justify the numerous folkloric uses of the plant parts in the treatment of some common ailments such as diarrhea, dysentery, fever, cough, pain and skin infections.

The secretarybird, the only species of the family Sagittariidae (Falconiformes), inhabits all of sub-Saharan Africa except the rain forests. Secretarybird, its vernacular name in many languages, may be derived from the Arabic “saqr at-tair”, “falcon of the hunt”, which found its way into French during the crusades. From the same period are two drawings of a “bistarda deserti” in a codex by the Holy Roman Emperor Frederick II (1194–1250). The original sketch obviously, together with other information on birds, came from the court of Sultan al-Kâmil (1180–1238) in Cairo. Careful examination led to an interpretation as Sagittarius serpentarius. Two archaeological sources and one nineteenth century observation strengthened the idea of a former occurrence of the secretarybird in the Egyptian Nile valley. André Thevet (1502–1590), a French cleric and reliable research traveller, described and depicted in 1558 a strange bird, named “Pa” in Persian language, from what he called Madagascar. The woodcut is identified as Sagittarius serpentarius. The text reveals East Africa as the real home of this bird, associated there among others with elephants. From there raises a connection to the tales of the fabulous roc, which feeds its offspring with elephants, ending up in the vernacular name of the extinct Madagascar ostrich as elephantbird.

The Impact

ABSTRACTAlthough Britain has never had a set of policies explicitly labelled ‘family policies’, most if not all social policies are implicitly family policies because they are based on certain assumptions about the nature of relationships between the sexes and the generations. By careful examination of the detail of the legislation and administrative rules, together with the way in which services are allocated and used, it is possible to expose these assumptions and show that they are not only consistent between policies but very persistent over time. This paper first examines the assumptions concerning the division of unpaid labour within the family whereby women care for the young, the sick and the old and for able-bodied adult men (their husbands). The examples are selected from a variety of income maintenance systems and services for children, the old and the disabled. Particular attention is focused on the extent to which it is recognized that women are at the same time workers in the labour market and unpaid domestic workers in the home. The second part of the paper analyses the impact on their participation and opportunities in the labour market of the ideology which accords to women the primary responsibilities for caring for other members of their family. The perpetuation of such an ideology favours the interests of men and frequently the interests of the economically powerful, but it is not assumed that these interests always coincide.

A case of Salmonella bredeney meningitis with recovery in a 19 day old infant is reported. This is the youngest patient with Salmonella meningitis known to have recovered. This is the second known case of Salmonella meningitis with recovery in a patient less than one month of age. Treatment with multiple antibiotics and chemotherapy both parenterally and intrathecally produced rapid improvement. An equally effective supportive blood transfusion may have aided this recovery. The use of chloromycetin after discontinuance of all other antibiotics was effective in producing a clinical recovery without relapse. No sequelae were noted at the end of a three month observation period. Attempts at discovering the carrier state of the infesting organism by careful examination of the family revealed no source of infection.

The present study is set to investigate the comparative chemotaxonomic investigations on Amaranthus hybridus L. and Amaranthus spinosus L. which belong to the family Amaranthaceae. They are dicots pre-dominantly found in the Niger Delta Tropics, Nigeria. The species are annual erect herbs with flower inflorescences as elongated spikes which are mostly paniculate occurring at ends of branches in globose fashion in axils of leaves.The nodes often have pair of axillary spines. Flowers are small, greenish with male ones at the top while the female ones below the clusters and stem is greenish but often reddish with one-seeded capsule as fruit in Amaranthus spinosus which attains up to 80 ± 20cm in height whereas A. hybridus differ in absence of a pair of axillary spines, the stems are greenish or slightly pinkish which grows up to 100 ± 10cm in height. A. hybridus is more of a vegetable and has alternate phyllotaxi and narrow cuneate base. Fruits from both species are circumscissile capsules and their inflorescences are terminal racemes positioned at their axils with female perianth segments of five. Epidermal studies revealed amphistomatic stomata which is anisocytic  type for both species. The stomatal index for A. spinosus adaxial foliar epidermis is 20% and the abaxial 20% whereas for A. hybridus adaxial is 20% and abaxial foliar stomatal index of 20%. Anatomical studies revealed open vascular system, collenchyma dominating the hypodermis while parenchyma occupied the general cortex and pith regions. A. hybridus has more vascular bundles and trichomes, and wider pith than A. spinosus. Phytochemical studies showed the presence of tannins, saponins, alkaloids, and flavonoids are present in A. spinosus while alkaloids were absent only in A. hybridus. This may be the reason why A. spinosus is used more in tradomedicine than A.hybridus which served more as vegetable. Key Words: Morphology, Anatomy, Phytochemistry, Amaranthus, Amaranthaceae

Plant Arabidopsis Thaliana

Abstract Crucifer flowers have a stereotypical plan and much of the floral diversity in the family is revealed only by careful observation. This statement holds true for the flower of Stanleya elata, a relative of the model plant Arabidopsis thaliana, which exhibits a number of distinct features that highlight the value of crucifers in comparative studies. Such comparative approaches in combination with new imaging and genomic technologies provide novel insight into floral structure and diversity.

The absorption and translocation of14C-labeled α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine (trifluralin) and 2-(3,4-dichlorophenyl)-4-methyl-1,2,4-oxadiazolidine-3,5-dione methazole from nutrient solutions of various temperatures by(Arachis hypogaeaL. ‘Starr’) seedlings were determined. The accumulation of trifluralin in roots at 24 hr after exposure to trifluralin was greatest at 21 C and decreased at higher temperatures up to 38 C. The amounts of trifluralin translocated and accumulated in hypocotyls, tops, and cotyledons were small but generally increased with temperature. The initial rate of absorption of trifluralin was greater in excised lateral root tips than in tap root tips, but there was a greater accumulation in excised tap roots at 24 hr. The initial rates of absorption were higher for excised lateral roots at high temperatures. Total absorption of trifluralin at equilibrium was not proportional to the initial rates of absorption but was highest at low (21 C) and high (38 C) temperatures for excised lateral roots. The absorption of methazole by roots and translocation to other plant parts increased linearly with temperature, and it tended to accumulate in the mature leaf tissue.

The development and structure of diacytic (caryophyllaceous) stomata in vegetative and floral organs of five species of the family Caryophyllaceae has been investigated. The mature stomata are diacytic or anomocytic and rarely with a single subsidiary cell. The ontogeny of diacytic stomata is of the meso-perigenous type. The development of anomocytic stomata is of the perigenous type and that of stomata with a single subsidiary cell is mesogenous.

The ethnobotanical study carried out at Madingou (4°16' S, 13°33' E) focuses on medicinal plants of the savannah zone. The survey used personal interviews and focus groups. Informants consisted of the inhabitants, whose age varies from 18 to 60 years or more. A total of 80 plant species were cited in the traditional pharmacopoeia. These plants are used in 66 recipes for treating 43 different diseases and symptoms, grouped in 11 major affiliations following the disease and symptoms sphere. Infectious and parasitic diseases is the most important group (23.25%), followed by the ill-defined symptoms and signs (13.95%) and the digestive system (11.63%). Five modes of administration were noted. The most preferred being the oral voice (38.75%). Among the 7 types of plant parts cited, leaves (65%) are preponderant. 8 modes of preparation were cited, the decoction (23.75%) being the most common. Of the 80 species listed, Allium sativum, Persea americana, Solanum nigrum, are among the medicinal plants most commonly used in Africa. Of the remaining species, 9 have been the subject of phytochemical studies all over the world. Ethnobotanical data show that a number of taxa, the medicinal properties of which are proved elsewhere, exist in the region and are not exploited, such as Millettia laurentii. Several species inventoried cover more than one aspect of indigenous knowledge, they are referred to as multipurpose plants and therefore the most vulnerable of the anthropic influences.

The present study deals with the phytochemical examination of Pachygone ovata (Poer.) Hook.f.& Thoms., an important medicinal plant from menispermaceae family. Leaf and Stem extracts were prepared by using different solvents systems and phytochemical screening was performed using the standard methods given by Harborne. Leaf and stem extracts were prepared from aqueous and organic solvents like petroleum ether, acetone, ethyl acetate and ethanol. Qualitative phytochemical analysis of the petroleum ether, acetone,ethyl acetate, ethanol and aqueous extracts prepared from P. ovata leaf and stem part. Leaf part revealed the presence of alkaloids, flavonoids, glycosides, cardiac glycosides, phenols and tannins. Stem part revealed the presence of alkaloids, flavonoids, glycosides, Resin, Steroids, phenols and tannins. The ethanolic extract showed higher amount of secondary metabolites than the other solvent extracts. This observation becomes important in the context of the therapeutically and drug applications of P. ovata.
