POLYARTERITIs NODosA, as its niame implies, is ain inflammatory lesion involving the -whole three coats of the arterial system in a noclal manner. The causation of this is unknown, but its peculiar affinity for wi(despread involvement of the smaller arteries results in a multiplicity of clinical signs and symptoms, and leads to confusion and difficulty in diagnosis. The more severely affected o...

OPHTHALMIA nodosa is defined as an inflammatory reaction in the eye to hairs of certain insects or vegetable material and derives its name from the nodular conjunctival reaction which they produce. Wagenmann (1890) first called it pseudotuberculosis, and it was renamed by Saemisch (1904). Three cases have been described in the British literature (Lawford, 1895; Foster Moore, 1929; Corkey, 1955)...

Scrophularia nodosa (figwort), an indigenous medicinal plant grows in moist and cultivated waste ground. It contains saponins, cardioactive glycosides, flavonoids, resin, sugar and organic acids. It is traditionally used for anti-inflammatory purpose and in skin disorders. It has diuretic and cardiac stimulant properties. The present studies were carried out on crude extract of Scrophularia nod...

How strong is selection for cheating in mutualisms? The answer depends on the type and magnitude of the costs of the mutualism. Here we investigated the direct and ecological costs of plant defense by ants in the association between Cordia nodosa, a myrmecophytic plant, and Allomerus octoarticulatus, a phytoecious ant. Cordia nodosa trees produce food and housing to reward ants that protect the...

A trial was conducted to suppress bacterial wilt of tomato (BWT) caused by Ralstonia solanacearum using biocontrol agents (BCAs) isolated from soils in Kalimantan, Indonesia. Five isolates were selected from 270 isolates as better performing BCAs through screening four times using a pumice medium. The isolates selected were identified as Burkholderia nodosa, Burkholderia sacchari, Burkholderia ...

PURPOSE Polyarteritis nodosa is one of the common forms of vasculitis with multiorgan involvement. Hearing loss may be the presenting symptom of this disease. The aim of this histopathologic study was to evaluate temporal bone changes in polyarteritis nodosa and assess the correlation between otologic manifestations and histopathologic findings. MATERIALS AND METHODS A retrospective human tem...

Polyarteritis nodosa has been the subject of comprehensive reviews covering most of its clinical and histological aspects (Smith and Zeek, 1947; Miller and Daley, 1946; Davson, Ball, and Platt, 1948). There are, however, four points which require clarification, and they are discussed in the present paper: (1) the early changes and the question of the so-called "fibrinoid " substance; (2) some h...

Current identification methods for the soft rot erwinias are both imprecise and time-consuming. We have used the 16S-23S rRNA intergenic transcribed spacer (ITS) to aid in their identification. Analysis by ITS-PCR and ITS-restriction fragment length polymorphism was found to be a simple, precise, and rapid method compared to current molecular and phenotypic techniques. The ITS was amplified fro...

Polyarteritis nodosa was first described as a clinico-pathological entity by Kussmaul and Maier ( 1866), who called it periarteritis nodosa. Ferrari (1903) first called the disease polyarteritis nodosa, a name that describes the pathology more accurately. The disease may be grouped with the collagen diseases-desseminated lupus erythematosis, scleroderma, rheumatoid arthritis and others. It is c...
