Studies on the ovarian development in the housefly Musca domestica vicina Macquart. II. Effect of a chemosterilant, hempa, on the ovarian development


, : Studies on the ovarian development in the housefly Musca domestica vicina Macquart. II. Effect of a chemosterilant, hempa, on the ovarian development. Japanese Journal of Sanitary Zoology 25(1): 57-64

The sterilising effect of hempa was studied in relation to ovarian development in Musca domestica vicina Macq.. The hempa was administered to both sexes in diluted milk throughout the experiment. Treatment at 0.02 or 0.004% reduced the viability of eggs laid by about two-thirds and one-half, respectively. Decreased egg production and complete sterility followed treatment at 0.1 or 0.25%.

In this study, we investigated the differences in calbindin D-28k (CB), calretinin, (CR) and parvalbumin (PV) immunoreactivity in the hippocampus of Zucker diabetic fatty (ZDF) rats and Zucker lean control (ZLC) rats. In addition, we observed the...
