A preliminary screening was carried out on five plants viz., Azadirachta indica, Citrus medica, Murraya koenigii, Ocimum tenuifloreum and Ricinus communis for their repellent activity against mosquitoes. The repellent activity was studied under natural conditions in the field making use of the traditional knowledge as background. Field observations were undertaken in houses wherein dried powder...

PURPOSE To study the glycoconjugates in the lacrimal sac epithelium of Japanese white rabbits with experimentally induced chronic dacryocystitis. METHODS Chronic dacryocystitis was induced by a subcutaneous injection of albumin followed by an injection of Staphylococcus aureus into the lacrimal sac. The histological appearance of the lacrimal sac was studied using the alcian blue-periodic aci...

As a tropical country with biodiversity, Indonesia is rich flora especially those potential as medicinal plants such Jarak Kepyar (Ricinus communis). Leaves of jarak kepyar communis) are used medicine for wounds, rash, abscess, and fever. Therefore, the purpose this study was to determine active compound in ethanol n-hexane extract leaves using phytochemical analysis GC-MS. The research method ...

Affinity chromatography has become the standard procedure for isolation of lectins [ I] . In its most general form, a ligand which binds to the lectin is linked covalently to a solid matrix. However, an insoluble or cross-linked polysaccharide for which the lectin exhibits affinity can also be used as the adsorbent. Notable examples of this approach include the isolation of concanavalin A using...

Cadmium (Cd) isotopes provide new insights into Cd uptake, transport and storage mechanisms in plants. Therefore, the present study adopted the Cd-tolerant Ricinus communis and Cd-hyperaccumulator Solanum nigrum, which were cultured under controlled conditions in a nutrient solution with variable Cd supply, to test the isotopic fractionation of Cd during plant uptake. The Cd isotope composition...

The ricinine content of etiolated seedlings of Ricinus communis increased nearly 12-fold over a 4-day period. In plants quinolinic acid is an intermediate in the de novo pathway for the synthesis of pyridine nucleotides. The only known enzyme in the de novo pathway for pyridine nucleotide biosynthesis, quinolinic acid phosphoribosyltransferase, increased 6-fold in activity over a 4-day period w...

AIM The aim of the present study is to make a histologic analysis the effects of a human demineralized bone matrix and a polyurethane resin derived from the Ricinus communis, on bone regeneration process. MATERIALS AND METHODS For this, 24 rabbits were submitted to two surgical calvaria bone defects, one on the right and another on the left side of the parietal suture. The animals were divide...

Context. Many diseases are associated with oxidative stress caused by free radicals. Objective. The present study evaluated the in vitro antioxidant and antibacterial activities of various extracts of aerial parts of Periploca aphylla and Ricinus communis. Materials and Methods. In vitro antioxidant activities of the plant extract were determined by DPPH and NO scavenging method. Superoxide ani...

The pattern of lectin histochemistry in formalin fixed, paraffin embedded normal jejunal and subtotal villous atrophy specimens from patients with gluten sensitive enteropathy were compared. There was no significant difference in the binding pattern of five lectins (Arachis hypogaea, Canavalia ensiformis, Lens culinaris, Phaseolus vulgaris and Triticum vulgaris) between normal and abnormal spec...

Well-defined ferritin-conjugated lectins were used to map glycoconjugates on the surface of sprouting neurons from rat superior cervical ganglion (SCG) and spinal cord (SC). The cultured neurons were exposed to the markers and processed for electron microscopy, and the number of ferritin particles per unit area of plasmalemma was measured in three different regions: perikaryon, neuritic shaft, ...
