Serum calcium, inorganic phosphate and heat-labile alkaline phosphatase (HLAP) have been estimated in maternal and cord sera of 120 pregnant women at labour. 75 women who did not take any vitamin D supplements during pregnancy showed statistically significant hypocalcaemia, hypophosphataemia and elevation of HLAP. Hypocalcaemia and hypophosphataemia were(More)
To study the effect of calcium and vitamin D supplementation on the incidence of toxaemia of pregnancy, 200 randomly selected pregnant women (supplemented group), were put on calcium (375 mg/day) and vitamin D (1,200 IU/day) supplements at 20-24 weeks of pregnancy onwards. Another 200 pregnant women constituted the non-supplemented group. At 32 and 36 weeks(More)
Serum calcium, inorganic phosphorus and alkaline phosphatase (SAP) have been determined in 75 lactating women and 25 controls. 25 lactating women were re-investigated after administration of calcium and vitamin D supplements of 1 month. Lactating women showed statistically significant hypocalcaemia and raised SAP. However, the elevation of the enzyme level(More)
In this review article an insight has been made into the strong possibility of the role of vasopressin (VP) in the control of circadian rhythms which has emerged from the results of the recent experiments in this field. A role for VP, which is identified in the suprachiasmatic nuclei (SCN) of mammals, as a neurotransmitter/neuromodulator in the central(More)
The effect of cutaneous tactile stimulation on motoneuron excitability was studied in 20 normal subjects and in patients of hemiplegia (n = 14) and paraplegia (n = 15) by plotting H-reflex recovery curves during application of twin pulses alone ("basal" H-reflex recovery curve), and twin pulses synchronized with electrical stimuli evoking tactile sensation(More)
In six healthy nonsmoker volunteers pulmonary diffusion capacity for Co (DLCO) was determined by single breath holding technique. Multiple measurements of DLCO were taken with PAO2 from 70 to 610 mm Hg, out of which at least 10 tests were performed between 100 to 140 mm Hg. A wide and non uniform inverse relationship was found between DLCO and PAO2 from 70(More)
Freshly weaned 30-day-old male Wistar rats were fed a vitamin D-deficient diet adequate in calcium and phosphorus for 3 months. On the 120th day of age three different doses of vitamin D were injected intramuscularly into three groups of rats and maintained for another month with water and a normal diet ad libitum. One group was continued with a vitamin(More)
Effect of lithium injections through chronically implanted cannulae into the bilateral suprachiasmatic nuclei (SCN) on the circadian rhythm of food intake was investigated in the rat. It was observed that the circadian rhythm was disrupted by injections of lithium at the beginning of the light as well as the dark phase of the LD cycle. In either case the(More)
