Snake venom toxins first transit the lymphatic system before entering the bloodstream. Ointment containing a nitric oxide donor, which impedes the intrinsic lymphatic pump, prolonged lymph transit time in rats and humans and also increased rat survival time after injection of venom. This pharmacological approach should give snakebite victims more time to(More)
Since the observations of Kidder et al. (8) that 8-azaguanine selectively inhibits the development of three types of mouse neoplasms, many investi gators have examined the carcinostatic power of this compound on a variety of cancer tissues in different animal species. It has been found that 8-azaguanine is active against many additional malignant neoplasms(More)
BACKGROUND This study examines the use of topical pharmacological agents as a snakebite first aid where slowing venom reaching the circulation prevents systemic toxicity. It is based on the fact that toxin molecules in most snake venoms are large molecules and generally first enter and traverse the lymphatic system before accessing the circulation. It(More)
Nature of Work: Commercial production and management of ornamental groundcovers is especially difficult due to the cyclic nature of market demand. During peak periods, production cannot keep pace with demand due to many species possessing strong apical dominance resulting in few cuttings per stock plant (3). Secondly, vining plants held during the slack(More)
The widespread use of effective, science-based interventions to motivate and sustain behavior change provides an important approach to reducing the spread of HIV. The process of disseminating information about effective interventions and building capacity for implementing them in field settings must be improved, however. Starting with a review of diffusion(More)
HortTechnology ● April–June 1996 6(2) Summary. Pesticides have been the primary method of pest control for years, and growers depend on them to control insect and disease-causing pests effectively and economically. However, opportunities for reducing the potential pollution arising from the use of pesticides and fertilizers in environmental horticulture are(More)
Activities of the enzymes of gluconeogenesis and of starch metabolism were measured in extracts of amyloplasts isolated from protoplasts derived from 14-day-old maize (Zea mays L., cv Pioneer 3780) endosperm. The enzymes triosephosphate isomerase, fructose-1,6-bisphosphate aldolase, fructose-1,6-bisphosphatase, phosphohexose isomerase, phosphoglucomutase,(More)
Table 1. Effect of paclobutrazol (paclo) on plant height and number of leaves developed on hollyhock at 2, 4, or 6 weeks after treatment. All application techniques were designed to deliver 0.10 mg paclo/10-cm Our objective was to determine the efficacy of a given dosage of β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1H1,2,4-triazole-1-ethanol(More)
DRAW(IT)N is a package of four similar interpretive programmes used in teaching computer graphics. The four programmes, each consisting of a Fortran interpreter and subroutines, permits the definition and manipulation of 2-dimensional or 3-dimensional objects in a batch or interactive mode; further-more objects as instances may be grouped in sub-assemblies(More)
Factors regulating assimilate transport into developing maize (Zea mays L.) kernels have been difficult to determine because of the structural complexity of basal kernel tissues and the damage that results from tissue dissection. The sensitivity of maize kernels to experimental manipulation is such that substantial maternal tissue is required to support(More)
