n-di-Propylacetate (nDPA, valproate) a GABA-T inhibitor, injected IP at the dose of 300 mg/kg antagonized agonistic behavior of isolated DBA/2 mice in a time-dependent fashion in parallel to an increase of GABA levels in olfactory bulb, striatum, posterior colliculus and septum. After 75 min, aggressive responses were higher than those after 15 to 45 min and significantly lower in comparison with those of saline injected mice. After 120 min aggressive behavior was not different from that of control mice. The concentration of GABA in the striatum and olfactory bulb returned to control value 75 and 120 min after drug administration, respectively. After 120 min GABA levels in posterior colliculus and septum were lower than those after 15 to 75 min, although significantly higher in comparison with those of saline injected mice. The results are discussed in terms of the possible involvement of olfactory bulb and striatum in GABA-mediated control of isolation-induced aggressive behavior in mice.

The aims of the present studies were (a) to determine the effects of pharmacological elevation of GABA by treatment with DPA (competitive inhibitor of GABA transaminase) on a form of aggression displayed by grouped female mice towards lactating and non-lactating intruders; (b) to estimate GABA levels in six different brain areas of intact and gonadectomized male and female mice. The results revealed that DPA treatment considerably reduced this form of aggression. Increased GABA levels, modulated by the hormonal state of the animals, were observed in most brain areas studied.

An inhibitor of GABA-T (sodium n-dipropylacetate), a GABA agonist (muscimol hydrobromide) and an inhibitor of GABA uptake (R,S) nipecotic acid amide were administered to DBA/2 isolated aggressive mice throughout three successive daily experimental sessions. Aggressive responses, measured by an automated device, were inhibited by the highest doses of the three drugs in each daily session. At the lowest doses, sodium, n-dipropylacetate and nipecotic acid amide failed to inhibit aggression in the first session while they were effective in the subsequent sessions. Muscimol was effective in the first session but did not differ significantly from saline in the second and third session. The highest doses of these three drugs did not affect spontaneous motor activity, indicating that the observed drug effects are rather specific.

The effects of drugs that antagonize or potentiate the action of brain gamma-aminobutyric acid (GABA) on shock-induced aggressive behavior in mice were investigated. In previous studies it has been shown that in C57 BL/6 strain shock-induced aggressive behavior is absent up to the 10th week of age and rises to the highest intensity after the 20th week, while at the same ages aggressive responses are lowest or absent in DBA/2 strain. GABA antagonist, picrotoxin and glutamic acid decarboxylase (GAD) inhibitor, D, L-allylglycine induced aggressive responses in non-aggressive 10 week old C57 BL/6 and 20 week old DBA/2 mice. GABA agonist muscimol hydrobromide, and GABA-T inhibitor sodium n-dipropylacetate inhibited aggressive responses in 20 week old C57 BL/6 mice. These effects were not related to changes in shock sensitivity and motor activity. The results strongly suggest that the GABAergic system is involved in the control of shock-induced aggressive behavior in mice and that this control is related to developmental and genetic factors.
