This study investigated the curative effects of notoginseny cream versus Hirudoid cream in the treatment of postinfusion phlebitis. Sixty-five patients who received peripheral infusion therapy during a 20-month period and had developed phlebitis were divided randomly into two groups. Group A was treated with notoginseny cream, a topical Chinese medicine developed and produced by the pharmacological department of The Second Affiliated Hospital of Sun Yat-Sen University. Group B was treated with heparinoid cream (Hirudoid, a commercial product from Germany). Significantly fewer applications of notoginseny cream were required to bring about the disappearance of signs and symptoms of phlebitis in the group A patients as compared with the group B patients for the same effect. The actual time of disappearance of the signs and symptoms of phlebitis also were significantly shorter in patients treated with notoginseny cream than with heparinoid cream.
This study evaluated the effects of reward, punishment, and reward + punishment on the impulsive responses of ADHD children. The impulsive responses of ADHD and normal control boys (30 per group) were compared during performance of a go/no-go task, administered under reward-only, punishment-only, and reward + punishment conditions. When differences in aggression, anxiety, and IQ between these groups were controlled for, results indicated that the impulsivity levels of the ADHD group were higher than the control group in all three reinforcement conditions. Also, the ADHD group was more impulsive in the reward + punishment condition, compared to the reward-only and punishment-only conditions, and there was no difference between the reward-only and punishment-only conditions. The control groups showed no difference across the three reinforcement conditions. These findings raise the possibility that the poor response inhibition of ADHD children may be related to both a generalized inhibitory deficit and a response modulation deficit.
