The serum, calcium, sodium, potassium and protein value were measured during different phases of reproductive cycle in Heteropneustes fossilis (Bloch) due to effect of varied calcium concentrations. The calcium value was higher then and Potassium value Protein during spawning period pointing a more demand of calcium which is necessary for the functioning of a enzyme thereby also helps in hardening of eggs while protein meets an extra energy demand during this period. An increase in serum, sodium level was also observed during spawning period than pre and post-spawning.

AbstractThe aim of this study was to develop an in vitro re-mineralization model in human serum. For this purpose a commercially produced demineralized human bone matrix (DBM) was incubated in samples of human serum pools obtained from two physiologically different groups. The first group consisted of young males and the second of older females. After incubation periods of 4 and 7days at 37°C, changes in the levels of calcium and inorganic phosphate content of the serum and DBM samples were measured. The results of the study showed that the change in mineral content of serum and DBM samples in both study groups was statistically significant. The decrease in serum calcium content and increase in DBM inorganic phosphate content were significant in the young group for longer incubation times. In the older group, both serum calcium and inorganic phosphate decreased and DBM mineral content increased for the same incubation time. When the two physiological groups were compared, statistically significant differences were identified for changes in mineral levels in both serum and the DBM samples. These data indicate that the mineral content of human serum decreases and that of DBM increases when these two materials are incubated together. These changes provide evidence for the re-mineralization of DBM. The model described here could also detect a difference in re-mineralization capability between two different groups of human sera.

Abstract. Deficiency of circulating 1α,25-dihydroxyvitamin D (1α,25(OH)2D) regularly occurs in hypoparathyroidism (HP) and pseudohypoparathyroidism (PHP). Osteomalacia is occasionally found in the two diseases. Two patients, one with HP and the other with PHP, both with symptomatic and biopsy-proven osteomalacia, were studied before and after treatment with 1α,25(OH)2D3. Laboratory values before treatment were as follows: serum immunoreactive parathyroid hormone was undetectable in the patient with HP and was elevated in the patient with PHP. Serum 25-hydroxyvitamin D, measured by binding assay, was 131.5 and 61.9 nmol/l (normal: 69.1 ± 15.9 nmol/l); serum 24,25-dihydroxyvitamin D, measured by binding assay, was 13.9 and 3.8 nmol/l (normal: 3.4 ± 1.4 nmol/l); serum 1α,25(OH)2D, measured by bioassay, was 28.6 and 29.0 pmol/l (normal: 77.3 ± 22.8 pmol/l) and, measured by receptor assay, was 36.2 and 41.0 pmol/l (normal: 71.8 ± 35.8 pmol/l) in the HP and PHP patients, respectively. Serum calcium was low and serum inorganic phosphate was high in both cases. Treatment with 1α,25(OH)2D3 (3–5 μg per day for 10–12 months) restored serum calcium and inorganic phosphate to normal, alleviated bone pain and healed the osteomalacia as shown on repeat bone biopsy. Our results provide further evidence that isolated deficiency of 1α,25(OH)2D may cause osteomalacia or rickets.
