Pharmacological screening of selective phytochemicals for common skin allergic disorder, which is defined by the occurrence of itchy and even painful wheels, angioedema or erthyma (Urticaria). The main cause of allergic reactions is chemicals, certain foods, insect stings, which often lead to the cause of histamine release, then the tiny blood vessels (capillaries) leak fluid. For induction of urt...
Mosquitoes are one of the important vectors of various diseases. Repellent activity significantly reduces contact with disease-transmitting mosquitoes. Essential oils have repellent activity that is being potentially developed as an alternative to commercial chemical pesticides. In this study, Lavandula angustifolia was used to evaluate its repellent activity against Ae. Aegypti. The repellent act...
PREVALENCE OF METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS (MRSA) IN CLINICAL SPECIMENS AND AMONG HOSPITAL STAFF NASAL CARRIERS IN KHARTOUM STATE
Staphylococcus aureus is a bacteria that causes a heavy epidemic disease burden worldwide. This study aimed to investigate the prevalence of Methicillin-Resistant Staphylococcus aureus (MRSA) and the presence of mecA gene as a virulence factor of S. aureus isolates from clinical isolates and hospital staff nasal carriers using a conventional PCR. A cross-sectional study involving eighty-one S. aur...
QUALITATIVE, QUANTITATIVE EXPLORATION OF PHYTOCHEMICALS AND DETERMINATION OF ANTIBACTERIAL ACTIVITY OF SARGASSUM WIGHTII
Marine carbohydrates play a crucial role in drug development and disease eradication as it is suggested as a promising bioactive material for its various properties. Seaweeds are the marine macroalgal source that contains a large amount of sulfated polysaccharides. Sargassum wightii (S. wightii) is one of the seaweed which possesses a wide range of pharmacological actions. The aim of the present w...
COMPARATIVE INVESTIGATION OF TOXICOLOGICAL CHARACTERISTIC AND SPECIFIC BIOLOGICAL ACTIVITY OF THE MEDIUM-CHAIN ALIPHATIC MONO- AND DIPEROXYCARBOXYLIC ACIDS
The comparative toxicological characteristic in-vitro and antimicrobial activity to perform stability tests of several linear medium-chain aliphatic monoperoxyacids (perC8–C12) and aliphatic diperoxyacid (diperC9) were studied. Substances of peroxide acids: perС8, perС10, perС12, diperoxyazelaic acid (diperC9) are in 5.6; 22.8; 64 and 1.6 times less toxic than reference substance - peracetic ...
