Modification of behavioral and neurochemical effects of cocaine by haloperidol.

Cocaine (20 mg/kg, i.p.) stimulated spontaneous motor activity (SMA) and induced stereotypy (ST) in rats. Haloperidol at 0.015 mg/kg, i.p. dose reduced or blocked cocaine-induced ST, but did not affect, drug-induced hyperactivity. At 0.03 mg/kg, i.p. dose of haloperidol, both behavioral effects were blocked. Cocaine decreased the norepinephrine (NE) and serotonin (5-HT) contents of diencephalon-midbrain (DM) and pons-medulla (PM) and increased dopamine (DA) contents in the DM and caudate nucleus (CN) at 20 min after its administration. Haloperidol (0.03 or 0.015 mg/kg) at 30 min postdrug produced opposite effects on the levels of NE, DA and 5-HT in the respective brain areas compared to cocaine. Given in combination, haloperidol reversed the effects of cocaine on the levels of NE, DA and 5-HT. Thus the cocaine-induced behavioral changes and their modification by haloperidol can be correlated to the neurochemical changes produced by these drugs alone or their combination.

Microfilaria of Wuchereria bancrofti in bone marrow smear.

Microfilariae of Wuchereria bancrofti were detected in seven cases of anemia in persons with asymptomatic filariasis. In three cases microfilariae could not be detected in the blood. Their presence in bone marrow may indicate the ability of microfilariae to cross the vessel wall.
