    The early effects of sympathectomy on bone blood flow (1984)
    Springer
    Calcified tissue international 36 (1984), S. 622-624

    Topics: Biology , Medicine , Physics
    Notes: Summary Several laboratories, including our own, have investigated the physiology of bone blood flow by perfusion of the tibia via the nutrient artery. Any damage caused to the nerve supply by cannulation of the artery might affect the results. The possible effect of such damage was investigated by measuring blood flow to the dog tibia using a microsphere technique, before and after sympathectomy. No effect was found and the tibial nutrient artery is therefore a suitable vessel for perfusion when estimating nutrient exchange in bone.

    Transcapillary exchange and retention of fluoride, strontium, EDTA, sucrose, and antipyrine in bone (1980)
    Springer

    Notes: Summary The extractions of85Sr2+,18F−, sucrose-14C, EDTA-51Cr, and antipyrine-14C in bone were determined by the multiple indicator-dilution method. Fluoride and strontium extractions were 18 to 70% during a single transcapillary passage, and those of EDTA and sucrose were from 11 to 59%, whereas extraction of antipyrine was 87%. Injections of85Sr2+ and18F− made when perfusion was done alternately with blood and plasma resulted in similar fractional extractions. When flow and extraction were measured simultaneously, extraction was related inversely to flow.

    The use of apical tissue analysis to determine the phosphorus status ofStylosanthes hamata cv. Verano (1981)
    Springer
    Plant and soil 59 (1981), S. 141-146 
    Details
    ISSN: 1573-5036
    Keywords: Apical tissue ; Critical P concentration ; Phosphorus deficiency ; Stylosanthes hamata cv. Verano
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A glasshouse experiment was conducted to determine the effect of plant age on critical phosphorus concentration in apical tissue ofStylosanthes hamata cv. Verano. Cut and non-cut treatments were included to simulate grazing and non-grazing situations. The critical concentration declined rapidly in both treatments during the 18 weeks following germination and remained relatively constant thereafter. The results are consistent with a higher phosphorus requirement for grazed plants compared with ungrazed plants.

    The effect of soil water status on critical phosphorus concentrations inStylosanthes hamata cv. Verano (1983)
    Springer
    Plant and soil 74 (1983), S. 467-472 
    Details
    ISSN: 1573-5036
    Keywords: Critical phosphorus concentration ; Soil water status ; Stylosanthes hamata cv. Verano

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The effect of soil water status on the critical phosphorus concentration (CPC) determined in apices and whole tops ofStylosanthes hamata cv. Verano was investigated in a glasshouse trial. The species was grown with six rates of P and three ranges of soil water potential and was harvested at 10 and 14 weeks after germination. The CPC of both whole tops and apices decliced between the two harvests. At the first harvest the CPC of both whole tops and apices increased as the soil water potential decreased but at the second harvest there was no effect of soil water potential on CPC. It is suggested that at the earlier harvest water stress was delaying physiological development, resulting in a CPC characteristic of chronologically younger tissue, but that by the second harvest the decline in CPC with age had ceased for all water treatments.
