In Table 5, results for glucose levels are slightly increased and fall between those of adrenaline and dexamethasone when test separately as can be seen in Table 2 and Table 3. Insulin levels significantly increase after twenty minutes and begin to decrease after ninety minutes, although still remaining on average ten times higher than initial levels.

Effect on Plasma Glucose

Figure 2: Effects of various hormones on plasma insulin

Discussion

The hyperglycaemic effects of Epinephrine are firmly established and their impact on the human body if well documented by the various researches in the recent biological medical industry. However the relevant research on the modulation of the Epi stimulated endogenous glucose production by the ingestion of glucose and insulin in the human body is still lacking. The results presented above have been presented so as to form this vital link and establish the impact of glucose and insulin on the human body and the comprehensive process of endogenous glucose production (Vicini et Al, 2002).. The aim of the contemporary researchers in the context of the overall effect of epinephrine on plasma glucose and insulin is to increase the research procedures and formulate a practical database of the acquired data. The exogenously increased plasma Epi concentrations within the human body have a drastic impact on the insulin and glucose dynamics. This is the reason why the research regarding this subject has to be increased so as to better understand the dynamics of the human body and the overall effect of adrenaline, dexamethasone and glucagon on plasma glucose and insulin. \

The hyperglemic effects of epinephrine on the human liver and on the overall functioning of the human body are firmly established in ...
