    A pharmacological and clinical comparison of prednisolone and betamethasone in rheumatoid arthritis (1982)
    Springer
    European journal of clinical pharmacology 23 (1982), S. 321-325 
    Details
    ISSN: 1432-1041
    Keywords: prednisolone ; betamethasone ; rheumatoid arthritis ; adrenal suppression ; chronic dosage ; anti-inflammatory activities

    Notes: Summary 1. Two oral corticosteroids, prednisolone (8 mg/day) and betamethasone (1 mg/day) have been compared in terms of efficacy and adrenal suppressive activity when used in chronic oral dosage in rheumatoid arthritis. 2. 20 patients were entered to a single blind crossover study receiving each drug for a two-week period. Clinical and laboratory assessments were performed. 3. At this dosage there was no significant difference between any of the clinical parameters assessed for either drug though patient preference was 13 for prednisolone and 7 for betamethasone. 4. At this dosage adrenal suppression was not equivalent, being significantly more marked with betamethasone. 5. The results suggest that prednisolone is the drug of choice for chronic dosage.

    A phenylbutazone dose-finding study in rheumatoid arthritis (1983)
    Springer
    European journal of clinical pharmacology 24 (1983), S. 773-776 
    Details
    ISSN: 1432-1041
    Keywords: phenylbutazone ; rheumatoid arthritis ; dose ; oxyphenbutazone ; side effects
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Different doses of phenylbutazone have been compared in a double blind study on 32 patients with rheumatoid arthritis in order to determine the minimum effective dose. Of 8 different dose levels studied (90 mg, 150 mg, 180 mg, 240 mg, 270 mg, 300 mg, 360 mg and 450 mg/day) the most efficacious was found to be 300 mg/day. Doses below this did not produce full benefit; no further improvement occurs with higher doses. Although 7/32 patients developed adverse reactions there was no relationship between these and the plasma levels of either phenylbutazone or oxyphenbutazone. An attempt was made to distinguish ‘responders’ from ‘non-responders’. We found no relationship between response and plasma levels of phenylbutazone or oxyphenbutazone.

    Colocasia esculenta (L.) Schott, Colocasia antiquorum Schott, how many species? 1. A preliminary investigation (1987)
    Springer
    Euphytica 36 (1987), S. 687-692

    ISSN: 1573-5060
    Keywords: Colocasia esculenta ; Colocasia antiquorum ; cocoyam ; taxonomy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The taxonomy of edible Colocasia (Cocoyam) is confusing. The existence of one species, C. esculenta var. antiquorum or C. esculenta and C. antiquorum as two separate species is controversial. Nine high yielding Nigerian cultivars of cocoyam made up of members of the two taxa were grown under the same environmental conditions. As a preliminary investigation, 17 characters were monitored and recorded to help in the classification of the cultivars. Results showed that cocoyams can be grouped into two separate species. The qualities possessed by TCe 23, Nwine and Ukpon cultivars which include pink tuber skin, long or club shaped cormels and non-irritation in the throat when boiled and eaten, clearly distinguished them from those of Tce 15, 19, 27, 36, Ede-ofe and Kochuom.

    A study of some factors affectingAgrobacterium transformation and plant regeneration ofDendranthema grandiflora Tzvelev (syn.Chrysanthemum morifolium Ramat.) (1993)
    Springer
    Plant cell, tissue and organ culture 33 (1993), S. 171-180

    ISSN: 1573-5044
    Keywords: Agrobacterium ; Dendranthema grandiflora ; transformation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract In an attempt to develop a system for producing transformed plants from explants ofDendranthema grandiflora, the susceptibility of the cultivar Super White to various wild-type strains ofAgrobacterium tumefaciens andA. rhizogenes was investigated. Tumour formation was not a reliable indicator of the ability of a related disarmed strain to mediate transformation. Following inoculation of explants with disarmedAgrobacterium strains, a number of shoots developed on selective media. However, none of these shoots were transformed. By co-cultivating stem internode explants with a mixed inoculum of wild-type and disarmed strains, it was possible to obtain a callus stably transformed withAgrobacterium carrying a disarmed T-DNA. Histological analysis of explants revealed that shoot regeneration initially occurred from the cells of the epidermis and subsequently from the cortex. However, the cells which were susceptible to T-DNA transfer were confined to the vascular tissue.
