Phytoecdysones ofRhaponticum integrifolium III. Integristerone B
SummaryFrom the flower heads ofRhaponticum integrifolium we have isolated a new phytoecdysone — integristerone B. It has been shown that it is 1β, 2β, 3β, 5β, 14α, 20R, 22R, 25-octahydroxy-5β-cholest-7-en-6-one.
Insect Moulting Hormones: Dacrysterone, a New Phytoecdysone From Dacrydium intermedium
Dacrysterone, a new phytoecdysone, has been isolated from the bark of Dacrydium intermedium and shown to be 5β-hydroxymakisterone A (6). Makisterone A also occurs in this plant.
Clinical chemical values and variations in Rasa Aragonesa ewes and lambs
Reference values of biochemical parameters in serum of Rasa Aragonesa ewes and their physiological variations were determined. Total proteins were 53.0–80.0 g/l, glucose 2.17–5.13 mmol/l, cholesterol 0.83–2.31 mmol/l, total bilirubin 1.85–6.49 μmol/l, urea 3.15–10.39 mmol/l, GGT 36–93 U/l (37°C), ALAT 11–33 U/l (37°C) and ASAT 71–209 U/l (37°C). Ewes were divided into three groups: A, 1- and 2-year-old ewes; B, ewes 3 and 4 years old; C, older ewes. Age had significant influence (P<0.05) on ASAT only during pregnancy, with higher levels for younger ewes. Blood parameters in lambs were determined at 5–10 d of life (nursing), 25 to 30 d of life receiving their mother's milk and 80–90 g of feed; and 45 to 50 d of life, weaned, receiving only solid feed. Serum urea and ALAT tended to increase with age, whereas total protein, globulins, cholesterol and GGT decreased with age. These values are of practical importance in the diagnosis of diseases and metabolic disorders in Rasa Aragonesa ewes and lambs under field conditions.
