Monosodium glutamate (MSG) administered during the neonatal period (days 2 to 11) resulted in a sequence of events that were manifested in adulthood. Reproductive dysfunction was seen in both female and male animals. Females treated with MSG had fewer pregnancies and smaller litters, while males treated with MSG showed reduced fertility. The MSG-treated(More)
We conducted a randomized, double-blind, placebo-controlled crossover study of folinic acid therapy (dl-Leucovorin, 15 mg/day) or placebo for males with Fragile X (fra(x)) syndrome. Twenty-one patients were enrolled in the study. The treatment periods were 3 months in length. Patients were followed with chemistry panels and complete blood counts. No(More)
Methylphenidate (MPH), the drug of choice in the treatment of attention deficit disorder with hyperactivity (ADD/H), has been shown to reduce the body stature of some patients. The present study was undertaken to determine if MPH suppresses growth in rats, and whether the clinical observation of a growth rebound phenomenon could be experimentally(More)
Methylphenidate (MPH), the drug of choice in the treatment of Attention Deficit Disorders with Hyperactivity (ADD/H), has raised concern regarding its suspected potential for reducing body stature in growing patients. In a previous study we demonstrated that neonatal rats treated with MPH (35 mg/kg, SC, twice daily) showed an acute growth impairment(More)
Responses of striate cortical cells in Midwestern Siamese cats to moving slits and stationary flashed spots were recorded and compared to similar data in common cat controls obtained under identical experimental conditions. Over 90% of the neurons sampled had receptive fields within 10 degrees of the area centralis. The proportion of binocularly excited(More)
Pharmacologic agents with a potential to attenuate the reinforcing properties of drugs of abuse may have an important role in the treatment of drug addiction. The reduction of drug self-administration and sweet solution intake are two common animal models employed to screen for promising therapeutic agents. When these agents are effective in suppressing the(More)
Prenatal exposure to psychotropic drugs has recently been shown to induce behavioral and brain neurochemical changes in the newborn. The long-term effects of pre- and postnatal exposure to methadone on the opioid (delta and mu) and adrenergic (alpha 2) receptors were investigated in two areas of the rat brain. Rat pups received prenatal treatment with(More)
Neonatal mice 1 and 5 days of age and older mice 25 days of age were injected with an increasing dose of monosodium glutamate (MSG) for a ten-day period and observed for at least 150 days. Both male and female animals in the 1- and 5-day age group treated with MSG showed large increases in weight over controls along with a shortened body length. The MSG(More)
