4.1.2.1 Changes in antioxidant enzymes and antioxidants in control and<br />

B.m&yi infected animals<br />

4.1.2.1.1 Superoxide dismutase<br />

The changes in <strong>the</strong> activity <strong>of</strong> SOD in <strong>the</strong> organs <strong>of</strong> infected and control animals are<br />

presented in Figs. 3-5. In control animals, all <strong>the</strong> organs (viz., <strong>the</strong> liver, testes, brain, heart<br />

and lungs) showed a continuous increase in <strong>the</strong> activity <strong>of</strong> this enzyme from 0 to 120 days.<br />

Contrary to this, in <strong>the</strong> testes, heart and brain <strong>of</strong> <strong>the</strong> infected animals, <strong>the</strong> activity <strong>of</strong> this<br />

enzyme showed an increasing trend upto 30 days and <strong>the</strong>reafter <strong>the</strong> enzyme activity declined<br />

s~gn~ficantly w0.05), while in <strong>the</strong> liver, <strong>the</strong> activity increased sigmficantly upto 60 days and<br />

<strong>the</strong>reafkr declined. And in <strong>the</strong> lungs <strong>the</strong> enzyme activity showed increasing trend throughout<br />

and <strong>the</strong> activity was higher than that <strong>of</strong> control .<br />

4.1.2.1.2 Catalase<br />

The changes in <strong>the</strong> catalase activity are shown in Figs. 6-8. All <strong>the</strong> organs <strong>of</strong> <strong>the</strong><br />

control animals showed increase in catalase activity from 0 to 120 days. Compared to this,<br />

<strong>the</strong> tesw, heart and brain <strong>of</strong> <strong>the</strong> infected animals showed decline in <strong>the</strong> enzyme activity from<br />

30th day while liver showed significant m.05) decline from 60th day. However, <strong>the</strong> lungs<br />

showed a steady increase in catalase activity from 30 days (significant at F0.05) and <strong>the</strong><br />

increase was much higher than that observed in control.<br />

4.1.2.13 Clutathione-s-transferase<br />

The activity <strong>of</strong> GST in various organs <strong>of</strong> <strong>the</strong> infected and control animals are shown<br />

in F~gs. 9-1 1. The GST activity was found to increase in control animals from day 0 to<br />

day 120.
