Effect of zinc sulphate was studied on histamine-induced contractions on guinea-pig ileum. In doses of 1.72 X 10(-7)M or less no effects were observed. Zinc sulphate in doses of 3.44 X 10(-7)M, 6.88 X 10(-7)M and 1.72 X 10(-6)M produced dual effect. Short exposure of tissue for 10 min to zinc sulphate resulted in significant dose dependent potentiation of histamine effect whereas after washing ...

Green mature fruits of mango cv. SS-1 (Kala Chaunsa) were immersed for 10 minutes in 2.5, 5.0 or 7.5% calcium chloride (CaCl2.2H2O), calcium sulphate (CaSO4.2H2O) or calcium ammonium nitrate {Ca(NH4NO3)2} solutions. A control was also included in which fruits were dipped in fresh water for 10 minutes. The fruits were ripened at ambient temperature (25 ± 3 C) in boxes lined and covered with news...

The present study was undertaken to find out the potential of gum from Moringa oleifera to act as a binder and release retardant in tablet formulations. The effect of calcium sulphate dihydrate (water insoluble) and lactose (water soluble) diluent on the release of propranolol hydrochloride was studied. The DSC thermograms of drug, gum and mixture of gum/drug indicated no chemical interaction. ...

Since prehistory man has been aware of the importance of particle size in producing resources and wares with desired properties. Archeological evidence indicates that paints used for cave wall paintings are mixtures of finely pulverized pigmenting materials, predominantly carbon, ochre and hematite. Man came to realize that adding pulverized materials to clay not only improved its workability, ...

This experimental study was carried out to investigate the effect of medical grade calcium sulphate and β-tricalcium phosphate/ hydroxyapatite on new bone formation. Additionally, the study compared these materials for infection, resorption, biocompatibility, immune reaction, fi brotic encapsulation, foreign body reaction and physical attachment. Forty, fi ve-month-old female Wistar Albino rats...

Transient Receptor Potential Melastatin 3 (TRPM3) is a widely expressed calcium-permeable non-selective cation channel that is stimulated by high concentrations of nifedipine or by physiological steroids that include pregnenolone sulphate. Here we sought to identify steroids that inhibit TRPM3. Channel activity was studied using calcium-measurement and patch-clamp techniques. Progesterone (0.01...
