ABSTRACT An improved method for the assay of plasma progesterone by competitive protein binding is described. The improvement is based upon rigorous control of the variables, the compensation for and standardisation of interfering factors inherent in the method and the use of a human corticosteroid binding globulin, that meets the requirements for sensitivity at levels of 1.0 ng of progesterone and below. The assessment of the reliability of the individual steps in the method as well as that of the complete method is presented. The sensitivity of the method is around 0.2 ng progesterone per ml plasma. Accuracy was measured by adding progesterone in amounts ranging from 0.0 to 1.0 ng to 1.0 ml plasma. There was a linear relationship between the progesterone added and recovered throughout the entire range of values, with a coefficient of correlation (r) of 0.94. Of 52 related steroids tested, none was found which would remain associated with progesterone following extraction and purification and which would also compete with progesterone for binding sites.

The initial growth of turmeric is rather slow and takes about 4-5 months to cover the inter space. Therefore, the available space between the rows of turmeric could be effectively utilized by growing short duration crops like, vegetables, cereals etc. Hence, it is worthwhile to explore the possibilities of growing compatible crops with turmeric. With this background the experiment on effect of intercrops on growth and yield of turmeric was conducted at Agricultural Research Station, Bhavanisagar. Among the different intercrops, turmeric with cowpea recorded the maximum fresh rhizome yield per hectare (30.78 t ha-1) while turmeric + bhendi registered the maximum B:C ratio (2.68:1). Monocropping of turmeric recorded the lowest B:C ratio (1.67:1) among all the treatments.

Цель - исследование влияния куркумы длинной и галеги восточной на осмо- и ионорегулирующую функции почек крыс при аллоксан-индуцированном сахарном диабете и острой почечной недостаточности в эксперименте. Методика. Эксперименты выполнены на самцах крыс Wistar (n=70) с моделью сахарного диабета (1-я серия) и острой почечной недостаточности (2-я серия). В обеих сериях животные были поделены на 3 группы: крыс 1-й группы содержали на стандартном корме, крысам остальных групп в корм добавляли куркуму (2-я группа) или галегу (3-я группа) (2% от массы корма). На 7-е сут эксперимента проводили исследование диуретической и ионоуретической функций почек натощак и после 5% водной нагрузки. Концентрацию ионов в моче и плазме определяли методом пламенной фотометрии; осмотическую концентрацию биологических жидкостей - методом криоскопии; биохимические показатели крови - колориметрическим методом. Результаты. У животных с сахарным диабетом фоновый диурез, а также экскреция натрия и калия были статистически значимо выше, чем у контрольных животных. При острой почечной недостаточности наблюдался более низкий уровень диуреза и ионоуреза, особенно после водной нагрузки. Прием куркумы и галеги вызывал улучшение осмо- и ионорегулирующей функции почек у крыс с сахарным диабетом, и практически не влиял на эти функции почек при острой почечной недостаточности. Заключение. При сахарном диабете оба фитопрепарата вызывали понижение концентрации глюкозы, креатинина, мочевины и улучшение ионно-осмотических показателей плазмы крови, при этом эффект куркумы был выражен отчетливее. При острой почечной недостаточности эти фитопрепараты не давали описанного эффекта. Aim. To study effects of the phytomedicines, Curcuma longa and Galega orientalis, on osmosis- and ion-regulating renal functions in rats with experimental diabetes mellitus (DM) and acute renal failure (ARF). Methods. Experiments were performed in two series on Wistar male rats (n=70) with modeled diabetes mellitus (series 1) and acute renal failure (series 2). In each series, the animals were divided into 3 groups, 1) rats of group 1 receiving a standard diet; 2) rats of groups 2 and 3 receiving a standard diet supplemented with turmeric or galega (2% of food weight), respectively. On the 7th day of the experiment, the diuretic and ionuretic renal function was studied in fasting state and after 5% water loading. Concentrations of ions in urine and plasma were determined by flame photometry; osmotic concentrations of biological fluids were measured by cryoscopy; blood biochemical parameters were measured by colorimetry. Results. In diabetic rats, background diuresis and sodium and potassium excretion were significantly higher than in the control animals. In rats with acute renal failure, diuresis and ionuresis were significantly lower, particularly after the water loading. Turmeric and galega supplementation improved the osmotic and ion-regulating renal function in diabetic rats and left practically unchanged these functions in rats with acute renal failure. Conclusion. In rats with diabetes mellitus, both herbal remedies reduced concentrations of glucose, creatinine, and urea and improved ion-osmotic parameters of blood plasma with a more pronounced effect of turmeric. In acute renal failure, these phytomedicines did not produce the described effects.
