Bicarbonates

 

acid salts of carbonic acid H2CO3, for example, NaHCO3 (sodium bicarbonate). Bicarbonates are produced by the action of CO2 on carbonates or hydroxides in the presence of water. When heated they are converted into the neutral salts, carbonates, for example 2NaHCO3 = Na2CO3 + H2O + CO2. Unlike most carbonates, all bicarbonates are soluble in water. Calcium bicarbonate Ca(HCO3)2 is responsible for the temporary hardness of water. Bicarbonates play an important physiological role in the body, where they act as buffers regulating the uniformity of the reaction of blood.

Duodenal acidity primarily depends on a lesser amount of bicarbonate in the pancreatic juice and bile.
There is also a direct connection between the bicarbonate concentration and pancreatic juice flow and the elimination of enzymes.
McClave believed that while healthy people have a high bicarbonate concentration in the duodenum, patients with chronic pancreatitis have low bicarbonate concentrations.
The importance of plasma bicarbonate is also illustrated by in vivo experiments in which pancreatic secretion was studied under conditions of metabolic acidosis.
Out of group I (Ciprofloxacin orally with ORS) and II (Ciprofloxacin parenterally and parenteral fluid with sodium bicarbonate), diarrhoeic calves in group II showed better recovery than group I.
The response of therapeutic regimen in group V diarrhoeic calves (Ciprofloxacin orally, Ciprofloxacin parenterally, Parenteral fluid with Sodium bicarbonate and rice bran mixed with barley broken grains) was found outstanding than any other groups.
It was concluded that best therapeutic response was evoked with the use of Ciprofloxacin orally, Ciprofloxacin parenterally, Parenteral fluid with sodium bicarbonate and rice bran mixed with barley broken grains.
The bicarbonate in ORS as well as with Ringer's lactate has potential to immediately neutralize metabolic acidosis associated with diarrhoea.
Blood samples were drawn from the finger tip 3 times during each trial; upon arrival to the laboratory (pre ingestion), 60 min after ingestion of placebo or the bicarbonate solution (post ingestion) and during the 1st min of recovery (post exercise).
To evaluate the effects of sodium bicarbonate intake on swim performance and chosen biochemical variables a two-way ANOVA for repeated measures (trial, measurements over time) was used, followed by the Tukey's post hoc test for paired observations to determine the significance of differences.
The results of the ANOVA ([F.sub.(2.28)] = 5.63, p < 0.05) indicate a significant effect of sodium bicarbonate ingestion on swimming performance in youth athletes during the 4 x 50 m front crawl test protocol.
Potassium bicarbonate with salt was highly effective and provided the best adhesiveness values in the raw ground beef samples.
