Dialysis experiments on urinary immunoreactive human growth hormone by means of a collodion bag

Abstract A convenient method to assay human growth hormone in urine was described. The pH of 20 ml of urine was adjusted to 8.6 with 1 n NaOH, and the sample was centrifuged. To the supernatant was added 0.1 ml of 2% bovine serum albumin, and the sample was concentrated against a borate buffer, pH 8.6, in vacuo, by using a Sartorius membrane filter. The mean recovery ratio of added immunoreactive growth hormone was 91.9%.

Standard of Physical Strength of English and Japanese University Rowing Crews

The physical strength of the Oxford University crew and the crew of three Japanese Universities was examined and the following conclusions were obtained.1) The Oxford University crew are superior to the crew of the three Japanese Universities in the mean of height, weight, girth of chest, girth of neck, girth of waist, girth of right upper arm, girth of left upper arm, girth of right forearm, girth of left forearm; girth of right thigh, span of arms, breadth of chest, depth of chest, diameter of chest and strength of push.2) The crew of the three Japanese Universities are superior to the Oxford Uni. versity crew in the mean of trunk flexibility.3) The mean and the standard deviation of 22 items about the physical strength of English and Japanese crews are calculated. On the bases of the mean and the standard deviation, the standard for evaluation of physical strength which is divided into 5 classes, are made in both cases.4) In comparison with the difference of physical strength between American and Japanese professional base-ball players or Canadian and Japanese rugby football players, the difference of the physical strength between the crews of English and Japa. nese Universities is less on the whole.
