Combined effects of ethanol and MK 801 on locomotor activity in the rat.
The present study examined the effects of ethanol (0.75 g/kg IP) alone and in combination with the noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist MK 801 (0.1 mg/kg SC) on the locomotor activity of rats. Sixteen rats were treated with vehicle plus saline, MK 801 plus saline, vehicle plus ethanol, and MK 801 plus ethanol. Locomotor activity was quantified for a period of 12 hours following drug administration. Ethanol was found to significantly decrease locomotor activity whereas MK 801 significantly increased locomotion during the first 2 hours postdrug. In addition, there was a significant additive interaction between ethanol and MK 801 during this time period. Two to four hours postdrug, MK 801 was observed to significantly decrease locomotion. Four to six hours postdrug, ethanol-treated rats had significantly increased locomotor activity whereas MK 801-treated rats displayed significantly decreased locomotion. No significant interaction was found between ethanol and MK 801 4 to 6 hours postdrug. No significant effects of any of the drugs on locomotor activity were observed from 6 to 12 hours postdrug. These results suggest that ethanol and MK 801 produce a pattern of effects on locomotor activity which depend on the time elapsed following drug administration.

[Cryptorchism: basic concepts and hormonal therapy].
The authors analyze the clinical results of 368 cryptorchid testis that received intramuscular human chorionic gonadotropin (HCG), at the dose of 50 U/kg once a week for 6 weeks. The patients with inguinal anatomical abnormalities or only with subtle retractility were excluded. There was a correlation among the testicle position, the cryptorchism side, the patient's age at the time of the therapy and the results obtained. We observed (i) a delay on child referral; (ii) concurrence of cryptorchism and systemic diseases, most of them with genetical origin; (iii) better results was obtained in children with retractile testis, older than 4 years old and with bilateral cryptorchism. The efficacy of second hormonal treatment was only present in retractile testis that showed partial response to the first hormonal therapy. It is argued that, although the treatment of children under 2 is less effective, the possible prevention of testicular lesions for this early intervention justify the hormonal therapy between 6 and 9 months of life.
