Role of Black Salt to Reduce in Hypertension, Reality and Evidence Based Studies

Salt in diet is very important to make our life healthy and energetic. Quantity and quality of salt with appropriate ratio or balance in electrolytes which are responsible for volume of body, blood velocity, for functions of receptors and enzymes, to prevent inflammation, proliferation and to make balance in muscles contraction and nerve conduction through to avoid high stimulation of sympathetic nervous system. Hence, scanning and focus with monitoring and supply of healthy salt in limits may prevent volume overload, renal dysfunction & left ventricular hypertrophy, to prevent cardiac functions, to avoid the weaken gut immunity and also to prevent cerebral oedema, cerebral aneurysm and hypertension cause stroke. Control of salt with intake of low quantity and high quality with more frequency of intervals during 24 hours in required amount of salt in balanced electrolytes may help to avoid high salt sensitivity. Balanced salt intake is also important to avoid volume expansion and obesity with reduction of insulin resistance leads to prevent hypertension and diabetes which are leading risk factors for cardio-renal syndrome, cardiovascular morbidity and mortality. Our data suggested a 2.5-fold higher risk for high blood pressure in sea or white salt users versus black salt or Himalayan rock salt which showed more potassium and magnesium with low sodium ions as compared to sea salt.

Aluminium toxicity induced poikilocytosis in an air-breathing teleost, Clarias batrachus (Linn.).

The present study was undertaken to assess the toxicity of acid alone and two different sublethal concentrations of aluminium, (25% and 75% dose of 96 hr LC50 value in acidified soft water of pH 5) on red blood cells of a stenohaline catfish, C. batrachus for an acute exposure of 5 days. The scanning electron microscopic studies on all the three treated groups revealed several kinds of erythrocyte alterations and modifications with abnormal morphology. These included abnormal surface-wrinkling accompanied with excessive roughness on the membrane, erythrocytes with surface granulation in higher dose and finally the appearance of morphologically abnormal forms, the codocyte (target cell) and the stomatocyte. The results suggest that abnormality in the shape of erythrocytes could be linked to altered surface membrane area to volume ratio, decrease in cytoplasmic volume owing to reduced Hb content or increase in the amount of water content within the cell resulting from osmotic disequilibrium. In this context, the abnormal surface membrane morphology could be attributed to cytoskeleton fragility and defects in structural proteins. Further, the acid group exhibited a striking behavior of cellular adhesion and bonding to adjoining cell surfaces, culminating in several bunches which thereby reduces the surface area for gaseous exchange and could produce blocking effect while flowing through microcirculation.

Electron microscopic studies of the corpuscles of Stannius of an airbreathing teleost (Heteropneustes fossilis).

The ultrastructure of the corpuscles of Stannius (CS) of Heteropneustes fossilis reveals a homogenous cellular composition characterized by only one cell type, with large secretory granules and abundant ribosomal endoplasmic reticulum. These cells are comparable to the type 1 cell described in the CS of other teleosts; type 2 cells, whose presence is ubiquitous in the CS of freshwater species are absent in H. fossilis. Our data on the CS of H. fossilis demonstrate that not all freshwater species possess type 2 cells in their CS and these are not essential for life in freshwater
