The death rate was calculated using the following formula: {text I%},=,left[1-left text W_{text t}/ text W_{text 0}right)right],=,left[1-left textsents the death rate, W_{textesents the number of colonies in the UV irradiation group, W0 represents the number of colonies in the blank group.
Percentage inhibition of bacterial growth was determined by the following formula: {text{Inhibition}}; = frac{{{text{O}}.
Melanin content was calculated using the following formula: {text{Melanin}} ;{text{content}} ; = frac{{{text{OD}}475_{text{sample}} }}{{{text{OD}}475_{{{text{blank}},{text{control}}}} }} times 100.
Phagocytic activity was expressed using the formula: {text{Phagocytic activity}} = ({text{Number of phagocytizing cells}}/{text{Total number of phagocyte cells counted}}) times 100.
At the same time, the CrCl was calculated using different formulas, i.e., the Cockcroft formula ({text{CrCl}}; = ;frac{{(140; - ;{text{age}}); times ;{text{weight}}}}{{0.8; times ;{text{SCr}}}}) for men, with age in years and weight in kg [2].
% inhibition of DPPH was calculated by the following formula: {text{Inhibition of DPPH }}left( % right), =, left[ {{{left( {{text{A}}_{text{Control}} - {text{A}}_{text{Sample}} } right)} / {{text{A}}_{text{Control}} }}} right], times { 1}00.
For diverging cutter dimensions, the equivalent thrust is given by the formula: {text{M}}_{text{eq}} = {text{M}}_{text{B}}, { times },{text{k}}_{text{d}}, { times },{text{k}}_{text{a}} (18).
The moisture content of the mixture was calculated by using the following formula: {text{Moisture content }}left( % right) = frac{{{text{Initial mass}} - {text{final mass}}}}{text{Initial mass}} times 100,%.
Higher optical densities (OD) represent more viability of the cells and so the toxicity percent can be obtained from the following formula: {text{Toxicity}} = left(1 - frac{{{text{OD}}_{text{S}} }}{{{text{OD}}_{text{C}} }}right) times 100 (1)where ODS is mean OD of sample and ODc is mean OD of control.
