Isometric rowing strength of experienced and inexperienced oarsmen.

The significance of isometric muscle strength for rowing performance was studied. The questions investigated were: A) Is the isometric rowing strength (IRS) of oarsmen which is two to three times the dynamic force applied on the oar at maximal power rowing, a ratio which is equivalent to the maximal efficiency of Hill's force/velocity relationship? B) Is IRS higher among successful oarsmen that among those less so? C) Is isometric strength of individual muscle groups correlated to IRS? From measurments on 40 oarsmen the results showed: a) IRS among the most successful oarsmen was 2.6 times the dynamic force indicated in literature; b) IRS was 21 kp higher in the 7 international competitive oarsmen than in 22 national oarsmen, and 42 kp higher than IRS of 11 club oarsmen; and c) of eight other strength determinations only hand grip strength was correlated to IRS.

Serum lipids during oestradiol-valerate/norgestrel treatment of menopausal women. Double-blind study of a sequential preparation.

Thirty-three women aged 38-56 years, all with menopausal complaints, were treated after randomization during three cycles either with oestradiolvalerate/norgestrel suquential therapy or a placebo and then during three cycles with the opposite drug. Serum cholesterol, triglycerides, glycerol as well as plasma FFA and lipoprotein electrophoresis were studied before the institution of treatment, after each cycle, and 4 weeks after the intake of the last tablet. During the treatment period the triglyceride level was significantly lower than during the placebo period, whereas no changes occurred in other parameters.

Comparison of extra-amniotic administration of PGF2alpha, 0.9 per cent saline, and 20 per cent saline followed by oxytocin for therapeutic abortion.

168 patients between 10th and 18th week of pregnancy admitted to hospital for legal abortion were treated accordingly to three different protocols.
