The germfree leopard frog (Rana pipiens): preliminary report.

Eggs and sperm were aseptically collected from leopard frogs (Rana pipiens) and passed into sterilized flexible film isolators. Egg fertilization was accomplished, and germfree tadpoles were produced. The germfree tadpoles were active and free-swimming for 3 weeks, but only 6.2% survived to 4 weeks of age. None survived after the 4th week.

Change in the mental health field?

An analysis of the current roles of the federally funded community mental health center and the public mental hospital suggests that despite the rhetoric about a community mental health revolution, the mental field has yet to undergo significant change. Ideological, political, economic, and structural barriers-characteristics of the field itself-impede such change outside, inside, and across the centers and hospitals. Recent court decisions on patients' rights, however, have the potential for moving the field into a period where "bold new action" actually can occur.

Dichlorvos effects on estrous cycle onset in the rat.

Continuous exposure to dichlorvos (DDVP) vapors from birth in rats caused a statistically significant mean delay of 10 da in the onset of the first estrous cycle. DDVP, BUT NOT ITS PRIMARY METABOLITE (DES-METHYL DDVP), could be readily isolated from blood and ovarian tissue, and occassionally in minute quantities from the kidney and adrenal tissues. DDVP was recovered only once in 40 brain tissue samples examined.
