Abstract

Previously, preweaned rats have been shown to perseverate rather than alternate choices of goal arms over 2 trials in a Tโ€maze. In this study 16โ€day old animals were successfully induced to increase their rate of alternation to chance level in the present experiment by increasing the novelty value on Trial 2 of the previously unchosen goal arm. Similarly, 100โ€day old rats were encouraged to decrease their level of alternation by enhancing the novelty value of the previously chosen arm. An explanation for these findings was offered in terms of the escitatory and inhibitory effects of a stimulus, and the gradual development of inhibition in ontogeny.

Rats were restrained for 4 h or for 4 h per day on three consecutive days and blood samples were obtained 30 min after their release. The adenosine deaminase (ADA) activity in the serum was measured by a micro-method with quantitation of the ammonia generated by ADA. Repeated restraint stress signiยฎ

The in vitro culture of porcine bone marrow-derived mesenchymal stem cells (MSCs) was used for the investigation of adult stem cell biology. Isolated porcine MSCs possessed the ability to proliferate extensively in an antioxidants-rich medium containing 5% fetal bovine serum (FBS). Greater than 40 s
