2.Comparison on the Effects of2Different Treatment Methods on the Assaying of Triptolide Alcohol in Tripterygium Wilfordii Cut Crude Drug
China Pharmacy 1991;0(04):-
OBJECTIVE:To compare the effects of2different treatment methods on the assaying of triptolide alcohol in tripterygium wilfordii cut crude drug.METHODS:After concentration,tripterygium wilfordii cut crude drug water decoction underwent column chromatographic separation after adsorption with neutral alumina(Method1)and neutral alumina column chromatographic separation after ethanol precipitation and extraction by chloroform(Method2),respectively.Triptolide alcohol was determined by HPLC and the assaying result underwent pairing and t tests.RESULTS:There was significant difference between the2methods with the content determined by Method1significantly higher than that by Method2(P
3.Effective Postoperative Use of Dexmedetomidine in a Child with Severe Pulmonary Arterial Hypertension Secondary to Congenital Ventricular Septal Defect.
Korean Journal of Critical Care Medicine 2015;30(1):34-37
Although alpha2-adrenoceptor agonists are widely used as postoperative sedatives in adults, the postoperative effects in pediatric patients with secondary pulmonary arterial hypertension (PAH) due to congenital heart disease are not well known. We experienced a case of successful ventilator weaning with continuous intravenous administration of dexmedetomidine (DEX) after surgical correction in a 46-month-old child with congenital ventricular septal defect (VSD) with severe PAH. She underwent VSD closure on cardiopulmonary bypass (CPB). After successful weaning from the CPB, hemodynamics and oxygenation were stabilized on DEX and nitroglycerin in the intensive care unit. The patient was successfully weaned from the ventilator 46 hours after surgery. The transthoracic echocardiogram two weeks after surgery showed a closed VSD with no residual shunt and trivial tricuspid regurgitation (Vmax = 2.5 m/sec) without PAH.

4.Effects of Sulfur Dioxide on Lactic Dehydrogenase-Isozyme.
Korean Journal of Preventive Medicine 1970;3(1):111-119
Alteration of H-and M-isozymfs of Lactic Dehydrogenase(LDH) were observed in the various tissues after exposing the rats to 50ppm and 250ppm of sulfur dioxide. These isozymes of the respective tissue were separated by Diethlaminoethyl(DEAE)-cellulose from tile tissue homogenates of brain, lung and muscle, presenting the activities by rate of reduction of nicot inamids-adenine-dinucleotide (NAD+). Pure LDH and the coenzyme NAD (NAD) were directly treated with sulfur dioxide in vitro order to find out the direct to sulfur dioxide on LDH and NAD+ and the results were as follow. 1. In the normal tissues, the H-isozyme activity was dominant in the brain and heart, and tole M-isozyme in the muscle. 2. In the lung tissue of normal rats, there was no different between tole activity of H-and M-type of LDH. 3 When rats inhale sulfur dioxide gas in concentration of 50ppm and 230ppm, it appeared that the H-type tend to be suppressed in aerobic tissues and the M-type in anaerobic tissues. 4. In the lung tissue exposed to sulfur dioxide, both the LDH activities were suppressed. 5. It seems that LDH and the coenzyme (NAD ) are not directly affected by exposing in sulfur dioxide gas.

5.Experimental Seminal Vesiculitis Induced by Repeated Injections of Homologous and Heterologous Seminal Vesicle Tissue.
Korean Journal of Urology 1968;9(3):127-137
An experiment on seminal vesiculitis in rats induced by repeated injections of homologous and heterologous seminal vesicle tissue suspension with Freund's complete adjuvant was accomplished to produce an immune disease in the seminal vesicle for the purpose to find the cause of same type of lesion in human beings were divided into 7 In this study 65 healthy adult white rats which weighed from 150 to 250 gm. were divided into 7 groups are follows: Group 1. Six rats, control, injected with normal saline Group 2. Six rats, injected with adjuvant Group 3. Seven rats, injected with seminal vesicle tissue suspension Group 4. Six rats, injected with rat seminal vesicle tissue suspension and adjuvant with prednisolone Group 5. Seven rats, injected with rabbit seminal vesicle tissue suspension Group 6. Seven rats, injected with rabbit seminal vesicle tissue suspension with adjuvant. Rats in these 6 groups were injected weekly for 8 weeks and sacrificed on the sixty fourth day. Group 7. Twenty-six rate, rat seminal vesicle tissue suspension with adjuvant. Rats in this group were subdivided into four groups Group A. Five rats, injected 4 times and sacrificed on 64th day. Group B. Seven rats, injected 6 times and sacrificed on 64th day. Group C. Seven rats, injected 8 times and sacrificed on 64th day. Group D. Seven rats. injected 8 times and sacrificed on 92nd day. Seminal vesicles from all the rats sacrificed were histopathologically studied and results were obtained as follows. Significant histopathologic alterations suck as glandular atrophy, decreased secretoryactivity, interstitial fibrosis, edema. congestion and inflammatory cellinfiltration suggesting of noninfectious chronic seminal vesiculitis were obtained in most rats of Group 7. Severity of inflammatory reaction seemed to be accentuated according to the increase of frequency of the date of sacrifice not concerned. Those allergic reaction were appeared to be inhibited by administration of prednisolone.
