As per the World Health Organization (WHO), "natural medications incorporate herbs, home grown materials, home grown arrangements and completed home grown items, that contain as dynamic fixings parts of plants, or other plant materials, or blends. Chloroxylon swietenia DC. (Family: Rutaceae) is an important traditional medicinal plant used in the treatment of various ailments like fungal infection of skin, rheumatism, common cold, cough, ophthalmic infection and cataract, wounds and as an astringent. It is a tropical aromatic tree of dry deciduous forests popularly known as East Indian Satin Wood. The findings of this study will facilitate pharmacognostic standardization of the plant material and aid in the preparation of an herbal monograph for the species. Further studies on this plant must be carried out to explore some other important, necessary and unknown benefits. As the plant has multifunctional properties, this review is worthwhile and therefore it presents comprehensive analysed information on the phytochemical and pharmacological aspects of the botanical. Keywords: Chloroxylon swietenia, phytomedicines, pharmacological aspects, anti-feedant, anti-bacterial activity, IUCN, vulnerable species.

The hermaphrodite duct of pulmonate snails connects the ovotestis to the fertilization pouch. The duct is typically divided into three zones; aproximal duct which leaves the ovotestis, the middle duct (seminal vesicle) and the distal ovotestis duct. The seminal vesicle forms the major portion of the duct and is thought to store sperm prior to copulation. In addition the duct may also play a role in sperm maturation and degredation. Although the structure of the seminal vesicle has been described for a number of snails at the light microscope level there appear to be only two descriptions of the ultrastructure of this tissue. Clearly if the role of the hermaphrodite duct in the reproductive biology of pulmonatesis to be understood, knowledge of its fine structure is required.Hermaphrodite ducts, both containing and lacking sperm, of species of the terrestrial pulmonate genera Sphincterochila, Levantina, and Helix and the marine pulmonate genus Siphonaria were prepared for transmission electron microscopy by standard techniques.
