Effects of thymoquinone or capsaicin on serum luteinizing hormone (LH) Level in acrylamide challenged rats
Animals kept on acrylamide showed marked nadir in serum level of LH amounted to 63% compared to control animals. Concurrent administration of either TQ or capsaicin to animals challenged with acrylamide exhibited apparent increases in serum LH levels amounted to 95% and 78%, respectively compared to rats treated with acrylamide alone(Table 2) .
Effects of thymoquinone or capsaicin on testicular lactate dehydrogenase isoenzyme-X (LDH-X) activity in acrylamide-challenged rats
Acrylamide, however, exhibited apparent decrease in LDH-X activity amounted to 48% compared to control animals. Concurrent administration with TQ to rats challenged with acrylamide showed significant increase in LDH-X activity amounted to about 31% compared to animals treated with acrylamide alone. Capsaicin had no effect on LDH-X activity when given to animals kept on acrylamide compared to the group that received acrylamide alone (Figure 1) .
