Structure And Ultrastructure

Coronatine is a non-host-specific phytotoxin produced by several members of the Pseudomonas syringae group of pathovars. The toxin acts as a virulence factor in P. syringae pv. tomato, allowing the organism to multiply to a higher population density and develop larger lesions than mutant strains unable to produce the toxin. The most prominent symptom observed in leaf tissue treated with coronatine is an intense spreading chlorosis; this has been attributed to a loss of chlorophylls a and b in tobacco. Coronatine's effects on membrane integrity and cell ultrastructure have not been previously investigated. The present study describes changes in tomato leaves in response to treatment with purified coronatine, infection by a coronatine-producing strain of P. syringae pv. tomato, and infection by a cor" mutant.In contrast to H2O-treated tissue, coronatine-treated tissue showed a diffuse chlorosis extending approximately 5 mm from the inoculation site. Leaf thickness, cell number, and cell dimensions were similar for both healthy and coronatine-treated, chlorotic tissue; however, the epidermal cell walls were consistently thicker in coronatine-treated leaves (Figs, la and lb).

Observation Period

ABSTRACT Treatment with a thyroid preparation was used in 75 cases of non-toxic goitre. In 63 cases there was nodular goitre in 12 diffuse goitre. The observation period varied from 3 to 42 months. The size of the goitre decreased in 50 cases (68 per cent) of which 40 had a nodular goitre and 10 a diffuse goitre. In the 63 cases with a nodular goitre the size of the nodules decreased in 39 cases and the nodules disappeared completely in 2 cases (65 per cent). In 5 cases (7 per cent) there was no change in the size of the thyroid or the nodules. Temporary factitious hyperthyroidism appeared in 7 cases but subsided rapidly after adjustment of the dose. In one case an endogenous hyperthyroidism evidently developed, probably owing to initial latent hyperthyroidism. Treatment of non-toxic goitre with thyroid preparations or hormones is recommended 1) in diffuse goitre, 2) in nodular goitre as a trial and 3) after thyroidectomy for compressive goitre. The value of radioactive iodine uptake or excretion tests for the assessment of the response to treatment and the adjustment of the dose is emphasized.
