| Abstract: | 1. Glutathione content and GSH S-transferase activity in the midgut gland of Procambarus clarkii (P. c.) of different sex and body weight are presented. 2. Procambarus clarkii females' GSH concentration in the midgut gland decreases to a higher extent upon fasting, compared with males. 3. Procambarus clarkii females, both in control and fasting conditions, have a slightly higher GSH S-transferase activity than males. 4. Cadmium present in water only affects GSH content and GSH S-transferase activity (after 96 hr) in midgut gland, with cadmium chloride concentrations higher than 100 micrograms/l. |
