ABSTRACT
Objective To study the efficacy of movement imagination combined with biofeedback for stroke patients with upper extremity dysfunction. MethodsEighty stroke survivors were recruited and randomly divided into a movement imagination group ( n =40) and a movement imagination combined with biofeedback group ( n =40).Their EMG mean values during wrist dorsiflexion were amplified and calculated.Fugl-Meyer upper extremity function scores (FMAs) and the modified Barthl index (MBI) were recorded before and after 6 weeks of treatment.ResultsAfter 6 weeks of treatment the two groups had significantly higher mean EMG values,FMA scores and MBI scores,but the effects in the combination group were significantly better than those in the simple movement imagination group. ConclusionMovement imagination can be made more effective by combining it with biofeedback for promoting the recovery of stroke patients with upper extremity dysfunction.
ABSTRACT
The diploid type of Paragonimus westermani in Heilongjiang Province and triploid type of P.westermani in Liaoning Province were examined for amino acids by high performance liquid chromatography (HPLC).Eleven kinds of amino-acids of diploid type and 15 kinds of triploid type were found in metacercaria; 15 kinds amino acids of diploid type and 16 kinds of triploid type were detected in larvae.The amino acids were more abundant in larvae than in metacercaria and more in the triploid than in the diploid type.The predominant amino acids were cystine and Rlutamic acid.
ABSTRACT
Diploid and triploid types of Paragonimus westermani were compared in the aspect of ultrastructure of spermatogenesis. The results showed that the process of spermatoge nesis in the diploid type was normal. The cells at every stage are well developed. A great number of morphologically and functionally normal spermatozoa could be formed. On the other hand, the process of spermatogenesis in the triploid type was abnormal, the cells at every stage developed abnormally. They were apparently degenerated or va-cuolated, lacking organelles. The cytophore was broken into small particles. No normal spermatozoa were found (Figs. 1-5).
ABSTRACT
Diploid and triploid types of Paragonimus westermani had similar cbromosomal karyotypes, however, they differed in chromosome c-band patterns. Two of three homologues of the triploid resembled those of the diploid in c-banding pattern, while the remaining chromosomes showed a different pattern. Heterogcneity in homologues was observed especially in chromosome Nos. 2, 3, 5, 6 and 7 (Fig. l, 2). In the diploid chromosome specimen, mitotic and meiosic phases were observed, while only the mitotic; phase was found in the triploid chromosome.
