چکیده

Since a gonadotropin-inhibiting substance in human urine is precipitated by acidification of urine, comparisons of the gonadotropic activities and the inhibitory effects in urine after acidification and removal of precipitate and in untreated urine were carried out in bioassays. Gonadotropic activity in the supernatant of acidified urine, in which a gonadotropin-inhibitor was removed through precipitation, was somewhat higher than that in non-acidified urine in the ovulation method. Inhibition on ovulation was obtained in the rats in-

Combination Therapy with Losartan and α-Tocopherol in Acute Ureteral Obstruction-Induced Renal Excretory Dysfunction and Acidification Defect

Background: Previous study by the authors showed that a-tocopherol prevents oxidative stress but would not improve depressed excretory variables in post-obstructed kidney (POK) after release of 24-h unilateral ureteral obstruction (UUO). This study is a supplementary investigation on the effects of a-tocopherol combined with an antagonist of angiotensin-II type-1 (AT1) receptor on renal dysfunc...

Action of Ketene on Gonadotropic Hormones*

Ketene has been found to be a highly specific,acetylating agent for aqueous solution of proteins. It reacts only with amino, thiol, and phenolic hydroxy groups (1). Several investigators (24) have shown that the primary amino groups react most rapidly, while the hydroxy groups of tyrosine are acetylated at a much slower rate. The hydroxy groups in carbohydrate radicals of the protein molecule d...

Some of the Oxidation-reduction Properties of the Chorionic Gonadotropic Hormong

Gurin, Bachman, and Wilson (l-3) have recently made important contributions to our knowledge of the chemical nature of the gonadotropic hormone of pregnancy urine. They have given a method for the preparation of the hormone in a highly purified form and have described many of its outstanding chemical and physical properties. We have been especially interested in the reference of these authors t...

The Action of Cysteine or Cyanide upon Gonadotropic Extracts

Fraenkel-Conrat, Simpson, and Evans (1) have recently reported that hypophyseal gonadotropic hormones may be completely inactivated by cysteine in mildly alkaline solution, whereas prolan, the principle from human pregnancy urine, shows no loss of potency under the same conditions; they have concluded that the disulfide bonds are essential for the activity of the hormones of pituitary origin an...
