ABSTRACT
One hundred and forty-nine patients with moderate and severe organophosphorus poisoning were treated in Fangshan District Hospital, Beijing during July 2005 to July 2007, 77 cases of them with intravenous atropine and intramuscular pyraloxime methylchloride and 72 with intramuscular penehyclidime hydrochloride plus pyraloxime methylchloride. Time of atrepinization, number of medication injection, time of symptom disappearance, recovery time of cholinesterase, length of hospital stay in those with penehyclidime hydrochloride plus pyraloxime methylchloride were all better than those with atropine and pyraloxime methylchloride (P<0.05). Percentage of atropine poisoning, atropine dependence, organophosphorus poisoning rebound and adverse reaction in those with penehyclidime hydrochloride plus pyraloxime methylchloride were lower than those in those with atropine and pyraloxime methylchloride (P< 0.05).
ABSTRACT
Objective To study the changes of the four active substances endothelin(ET),calcitonin gene related peptide (CGRP), thromboxane B2 (TXB2) and 6-Keto-prostaglandin F1? (6-Keto-PGF1?) in plasma when they acted on . each other in the formation and development of diabetic retinopathy. Methods Using the method of radio-immunity,the levels of ET,CGRP,TXB2, 6-Keto-PGF,. in plasma were measured in four groups of patients with type 2 diabetes (group 1: 40 cases without retinopathy; group 2: 40 cases with primary retinopathylgroup 3. 40 cases with hyperplasia type of retinopath; group 4: 40 cases normal controls). Results The results showed that ET increased progressively (P
ABSTRACT
Objective To study the changes of the four active substances endothelin(ET),calcitonin gene related peptide (CGRP),thromboxane B2(TXB2) and 6-Keto-prostaglandin F1α(6-Keto-PGF1α) in plasma when they acted on each other in the formation and development of diabetic retinopathy.Methods Using the method of radio-immunity,the levels of ET,CGRP,TXB2,6-Keto-PGF1α in plasma were measured in four groups of patients with type 2 diabetes (group 1∶40 cases without retinopathy;group 2∶40 cases with primary retinopathy;group 3.40 cases with hyperplasia type of retinopath;group 4∶40 cases normal controls).Results The results showed that ET increased progressively (P＜0.01) with the prolonging of the duration of DM and the worsening of retina damage、CGRP showed a decreasing tendency (P＜0.05,P＜0.01) in the advanced stage of DM retinopathy.Rectilinear regression analysis showed that the association of ET/CGRP with TXB2/6-Keto-PGF1α became closer with the worsening of deabetic retinopathy (r=0.44,P＜0.05;r=0.596,P＜0.01).Conclusion The four active substances acted on each other in the formation and development of diabetic retinopathy.It had a significent meaning in the initial mechanism of DM,in the development of disease and in the direction of medication usage to understand their relationship.
