The effects of atropine and glycopyrrolate on anatomical dead space, one and three second forced expiratory volume, maximal expiratory flow rate, and total forced expiratory volume were determined in ten healthy volunteers. Using Fowler's single breath nitrogen analyzing technique, atropine was found to increase dead space by 19.2 per cent at one hour, declining to 11.02 per cent at four hours....

Full thickness skin loss in the lower extremity presents special difficulties to the surgeon and his patient. Soft tissue in juxtaposition to the wound is usually remarkably thin and poorly vascularized. Moreover, the base of the wound very often is exposed, dead, infected bone. These chronic, persistent, economically debilitative ulcerations, traumatic, vascular, metabolic, or infectious in or...

To reduce the incidence of surgical site infection (SSI) after radical cystectomy, a new closing method using subcutaneous continuous aspiration drain was developed and compared to the conventional closing method. The new method involved (a) closed aspiration with an indwelling aspiration drain without suture of the subcutaneous fat and (b) covering with hydrocolloid wound dressing after suture...

The effects of the methanol extract of the stem bark of Prosopis africana (Guill., Perrott. and Rich.) Taubert (Fabaceae) on bleeding/clotting and coagulation time, excision and dead space wounds were studied in rats. Also, the extract was subjected to antibacterial, and acute toxicity and lethality (LD(50)) tests. The extract significantly (P<0.05) reduced bleeding/clotting and coagulation tim...

ON-THE-FLY DYNAMIC DEAD VARIABLE ANALYSIS Joel Self Department of Computer Science Master of Science State explosion in model checking continues to be the primary obstacle to widespread use of software model checking. The large input ranges of variables used in software is the main cause of state explosion. As software grows in size and complexity the problem only becomes worse. As such, model ...

Delayed wound healing in diabetes is primarily associated with hyperglycemia, over-expression of inflammatory marker, oxidative stress and delayed collagen synthesis. This unmanaged wound is producing high economic burden on the society. Thus research is required to develop new and effective treatment strategies to deal with this emerging issue. Our present study incorporates the evaluation of ...

According to Hope [1] myiasis is a disease of human beings originated specially with dipterous larvae. Zumpt [2] defined myiasis as “the infestation of live vertebrate animals with dipterous larvae, which at least for a certain period, feed on host’s dead or living tissues, liquid body substances or ingested food”. These invasions may be benign in effect or may result in mild to violent disturb...

Good wound bed preparation is an essential aspect of wound care and effective wound healing. Removal of dead and necrotic tissue either through autolytic or interventional debridement, followed by good exudate management, inhibition of matrix metalloproteases and bacterial bioburden control should allow the chronic wound to process to closure. It is known, still, that wound healing in these cir...

According to Greek mythology, Achilles was fatally wounded in his heel, bled out, and died. Several unproven hypotheses mention poisoning, infection, allergy, hemophilia, thyrotoxic storm (ie, pain and stress), and suicide. The author, a plastic surgeon who often treats chronic wounds, proposes an additional scenario: Although not mortally wounded, Achilles was considered dead, because in his t...
