The formation of slough (dead tissue) on a wound is widely accepted as an inhibitor to natural wound healing. In this article, a system of differential equations that models slough/wound interaction is developed. We prove a threshold theorem that provides conditions on the amount of slough to guarantee wound healing. As a state-dependent time scale, debridement (the periodic removal of slough) ...

Plants have been used in traditional medicine for several thousand years. India is perhaps the largest producer of medicinal herbs and is rightly called the “Botanical garden of the World”. Murraya koenigii Linn. commonly known as Meethi neem, belongs to the family Rutaceae. The curry tree is native to India and it is found almost everywhere in the Indian subcontinent excluding the higher level...

BACKGROUND When shared by people who inject drugs, needles and syringes with different dead space may affect the probability of HIV and hepatitis C virus (HCV) transmission differently. METHODS We measured dead space in 56 needle and syringe combinations obtained from needle and syringe programs across 17 countries in Europe and Asia. We also calculated the amounts of blood and HIV that would...

BACKGROUND AND METHOD Severe chronic osteomyelitis with variable outcomes is still common among children in developing nations. There has been no consensus on the optimal method of treatment. We therefore prospectively evaluated the rates of wound healing and recurrence following open wound treatment of post-sequestrectomy dead spaces in 30 patients with haematogenous chronic osteomyelitis of t...

The petroleum ether, chloroform, methanol and aqueous extracts of the leaves of Ageratum conyzoides Linn. (Asteraceae) were evaluated for their wound healing activity in rats using excision (normal and infected), incision and dead space wound models respectively. The effects of test samples on the rate of wound healing were assessed by the rate of wound closure, period of epithelialisation, wou...
