1.Comparative effects of Panax notoginseng saponins on hemodynamics of internal carotid artery and superior mesenteric artery in anesthetized rats
Chinese Pharmacological Bulletin 1987;0(03):-
The effects of Panax notoginseng saponins (PNS) and verapamil(Ver)on hemo-dynamics of internal carotid artery and superior mesenteric artery were determined and compared in anesthetized Sprague ~ Dawley strain rats. PNS 30-150 mg ? kg-1 iv was shown to reduce the mean blood pressure, internal carotid arterial resistance and superior mesenteric arterial resistance by 11 % ~19%, 14%~27%,23%~ 39%respectively. Meanwhile, the mesenteric ar-terial blood flow increased.by 16%~51%. Ver showed similar reflects as PNS. The results indicated that the vasodilation effects of PNS and Ver are vascular selective, that is PNS and Ver are more potent in dilating the mesenteric artery than the internal carotid artery.

Objective To test the effects of restuscitation with air or oxygen on the blood gas and cerebral superoxide dismutase (SOD) concentration in neonatal rats with experimental intrauterine asphyxia. Method Seventy-seven neonatal rats were randomly (random number) divided into three experimental groups: sham operation group (SHAM), air resuscitation group (AR), and oxygen resuscitation group (OR). In groups AR and OR, animal models of intrauterine asphyxia were established and then resuscitated with air (AR) or oxygen (OR) for 30min. Comparison was made between groups including the mortality 0 hour after resuscitation, and the levels of blood gas and cerebral SOD concentrations 0 h, 6 h and 24 h after resuscitation. Results Mortality of neonatal rats in SHAM group, AR group and OR group were 0 (0/24), 0 (0/26) and 3.7% (1/27), respectively (P >0.05). The average levels of blood PaO2 in OR group and AR group 0 h after resuscitation were (69.2 ± 8.2)mmHg and (55.5±10.3) mmHg,respectively (P=0.004). Blood pH and PaCO2 and BE levels in OR group 0 h after resuscitation were not significantly different from those in AR group (P>0.05). Blood pH, PO2, PCO2and BE levels in OR group were also not significantly different from those in AR group 6 h and 24 hours after resuscitation. The average concentrations of cerebral SOD in OR group 0 h and 6 hours after resucitation were (38.3±9.8) U/mgprot and (8.6±3.6) U/mgprot, and those in AR group were (53.8± 10.6) U/mgprot and (13.0±4.6) U/mgprot, respectively (P = 0.003, 0.04). The cerebral SOD concentration in OR group 24 hours after resuscitation was not significantly different from that in AR group (P>0.05). The cerebral SOD concentrations in SHAM group 0 h,6 h and 24 hours after resuscitation were much higher than those in OR group and AR group (P<0.05). Conclusions Resuscitation with air is as good as pure oxygen in neonatal resuscitation, in respect of early mortality and improvement of acidosis in neonatal rats after intrauterine asphyxia. Resuscitation with air will generate less radical oxygen species than pure oxygen in neonatal rats after intrauterine asphyxia.

The paper is to report the study of pharmacokinetics of transdermal administered nicotine in the brain of freely moving rat by using microdialysis with stable labeled isotope as internal standard. The pharmacokinetic behavior of nicotine in Sprague Dawley rat brain was investigated after intranasal administration (3.75 mg). Brain fluid samples were collected by intracerebral microdialysis with DL-nicotine as internal standard. Concentrations of nicotine and DL-nicotine in the sample were measured by HPLC-MS/MS. Main pharmacokinetic parameters were calculated and analyzed by Das 2.0 pharmacokinetic software. The recovery of nicotine and the delivery of DL-nicotine were the same. The fate of absorption and distribution was two compartment model and the values of t1/2alpha was 170.31 min, t1/2beta was 263.30 min and the AUC(0-infinity) was 2.75 x 10(5) microg x L(-1) min separately. DL-nicotine can be used to calibrate the recovery of nicotine, and the new method of stable isotope microdialysis can be used to study the pharmacokinetics of freely moving rat. It will make sense for the treatment of addiction of tobacco and provide a new thought for the research of pharmacokinetics-pharmacodynamic combination.

Objectives To analyze the risk factors for transfusion in very low birth weight infants and to explore the strategies for prevention of anemia. Methods Neonates with gestational age <37 weeks and birth weight <1500 g admitted from January 2015 to June 2016 were included. The neonates were divided into blood transfusion group and non-blood transfusion group. The general conditions and complications were compared, and the risk factors of blood transfusion and the related factors were analyzed. Results One hundred fifty cases of very low birth weight infants were included, among whom 108 cases were from blood transfusion group and 42 cases were from non-blood transfusion group. Compared with the non-blood transfusion group, the gestational age and body weight of the blood transfusion group were smaller, the basic hemoglobin was lower, the parenteral nutrition time was longer, and the total volume of blood collection in hospital was higher, and these differences were all statistically significant (P all<0.05). The incidence of bronchopulmonary dysplasia (BPD), acute respiratory distress syndrome (RDS) and patent ductus arteriosus (PDA) in the blood transfusion group were higher than those in the non-blood transfusion group, and they were all statistically different (P all <0.05). Multiple linear regression analysis showed that the volume of blood transfusion was higher when the gestational age and body weight were smaller, the longer parenteral nutrition was needed, and the total volume of blood taken from the hospital was higher (P all <0.05). Conclusions The gestational age, body weight, parenteral nutrition time and the total volume of blood collection in very low birth weight infants have different effects on blood transfusion risk and transfusion volume. The incidences of BPD, RDS, and PDA in infants with blood transfusion are higher.
