An experimental study of 300 mice exposed to pitch(3 gm.dissolved in 10 ml.of 80% benzene solution)obtained from 4 different sources,name- ly Anshan coal-tar pitch,Yu-men petroleum pitch,Dairen petroleum pitch or commonly known as Russian crude oil and the Asia Oil Company, USA,was carried out over a period of 350 days. From the beginning a group of these experimen- tal animals was exposed to artificial sun-ray for 2 hours a day.The results of our experiment indicate that pathological changes of different degrees of severity,such as chronic dermatitis and tumor formation,were the commonest effect of pitch on skin both in the exposed and non-ex- posed groups while the control group(exposed to 80% benzene only)showed only slightly acute dermatitis. The pathological changes as observed both in gross appearances and histological findings are given in detail. The course of tumor formation as found in both the exposed and the non-exposed groups may be classified in the order of time sequence as benign squamous papilloma,malignant squamous papilloma and finally squamous-celled carcinoma; also a few cases of sarcoma and a few cases of so- called“Myoblastoma”. Through the action of photosensitivity to the exposed group,the prolongation of the latent period of tumor formation,the effectiveness in the development of dermatitis and malignant changes in tumors were clearly observed in the process of the pathological changes. The relative potency of the carcinogenic pitch obtained from the above sources has been calculated by means of the statistical analysis of both the incidence and the length of time for the development of the cutaneous tumors.

Our previous studies indicated that tetrandrine and demethyl-tetrandrine caused a fall of blood pressure in anesthetized cats. Both compounds produced a direct as well as a reflex vasodilatation in the isolated rabbit's ear.

Our previous studies indicated that tetrandrine and demethyl-tetrandrine caused a fall of blood pressure in anesthetized cats. Both compounds produced a direct as well as a reflex vasodilatation in the isolated rabbit's ear. In order to elucidate the mechanism of these effects, the interaction of these two alkaloids with acetylcholine and adrenaline, the influence on the sympathetic ganglian and the pressor response by occlusion of the common carotid arteries were investigated with the following results: (1) Tetrandrine 0.5 mg/kg and demethyl-tetrandrine 1.5 mg/kg injected intravenously prolonged the hypotensive effect of acetylcholine. The hypotensive effect of these two alkaloids was reduced to some extent by previous administration of atropine. (2) The effects of tetrandrine and demethyl-tetrandrine on blood pressure was not influenced by adrenaline and vice versa. (3) Tetrandrine and demethyl-tetrandrine did not reveal ganglion-blocking action, but during an abrupt and severe fall of blood pressure induced by these alkaloids, the sympathetic ganglion was temporarily excited (for about 5 min.) as indicated by spontaneous contraction and prolongation of contraction of the nictating membrane of the cat. (4) In view of the fact that these two alkaloids could inhibit or eliminate the pressor response to serial occlusion of the bilateral common carotid arteries in the cat, and that the hypotensive effect was not influenced by bilateral section of the sinus nerves, the vasomotor center or central sympathetic structures might be affected. (5) Repeated administration of demethyl-tetrandrine resulted in tachyphylaxis in its effect on blood pressure. (6) It can be concluded from the above experiments that the hypotensive effect of tetrandrine and demethyl-tetrandrine is caused by the following factors: (a) a direct and reflex vasodilatation, (b) an inhibition of vasomotor center or central sympathetic structures, and (c) a parasympathetic effect.

1.甲素及乙素預先作靜脉注射,能使乙醯胆硷的降压作用加强及作用时間延長,同时阿託品可部分取消甲素及乙素的降压作用,可以認为其有拟似胆硷反应系統(M-系統)的作用。 2.甲素及乙素对腎上腺素之升压作用並無影响。 3.甲素及乙素对交感神經节並無阻断作用,相反,当甲素及乙素产生显著血压下降时,往往引起交感神經节的短暫兴奋現象。 4.甲素及乙素可取消或減弱因压迫頸动脉所引起的升压反射,二者的降压作用並不受切断二侧竇神經所影响,可以推想其对血管运动中樞或交感神經中樞有抑制作用。 5.甲素及乙素对血管的直接及反射性舒張作用,对血管运动中樞或交感中樞之抑制及对胆硷反应系統的拟似作用等,应可視为它們降压作用之主要机制。 6.甲素及乙素之药理性質相似,但乙素之降压作用較甲素为弱且易产生急速耐受現象。

The clinical features of 415 attacks of rheumatic fever observed in 365 adult patients are described, and some of the diagnostic problems are discussed, 102 of the attacks were considered to be initial and 313 recurrent attacks. Pre-existing chronic valvular disease was diagnosed in 184 cases. The attack rate of rheumatic fever by season was found to be highest in late Winter and Spring, with the peak incidence in the months of March and April. A history of preceding sore throat was elicited in 41% of the rheumatic attacks, and inflammatory signs in the pharynx and tonsils were observed in 58.6% of the attacks. The antistreptolysin O titer was above 250 units in 80% of the cases examined. Among the clinical manifestations arthritis and carditis were most common, occurring in 55.7% and 49.9% respectively, while arthralgia without frank inflammatory signs was noted in 30% of the attacks. The incidence of arthritis was lower in the cases with chronic valvular defects than in cases without. In 29% of the cases ECG abnormalities constituted the sole clinical evidence of carditis. Since prolongation of P-R interval or higher grades of atrioventricular block are relatively common in rheumatic fever and other manifestations of rheumatic carditis like murmurs, cardiac enlargement, pericarditis and heart failure are equally non-speclfic, it is suggested that a-v block be included as evidence of carditis rather than considered as a minor manifestation if one adopts Jones' criteria for the diagnosis of rheumatic fever. In the presence of chronic valvular disease frank arthritis was uncommon and signs of carditis were often masked by those of valvular defects so that in 38.5% of cases the diagnosis of rheumatic activity had to depend upon a combination of clinical and laboratory signs generally concidered as minor rheumatic manifestations according to Jones' criteria.

1.本文报告成人急性风湿热366例,經住院观察的急性发作共415次,其中102次診断为初发,313次为复发。发作見于已有慢性心瓣缺损者計184例(218次发作),无心瓣缺损証据者182例(197次发作)。对发病季节、与溶血性鏈球菌感染的关系、临床表現、实验室发見、病程及病死率等作了分析。重点討論了本病的診断问題。 2.风湿热在春冬二季的发病率較高,41%的风湿发作前有咽痛,58.6%的风湿发作时咽部尚有炎症表現,仅24.7%的风湿发作前后均无咽炎的証据。約有80%发作中抗鏈球菌溶血素“O”滴定度在250单位以上。以上数字有力地說明了风湿热和鏈球菌感染之间的密切关系。 3.临床表現中以关节炎最为常見,发生率为55.7%,仅有关节酸痛的有30%。已有慢性心瓣缺损的病例中仅37.6%有关节炎,其发生率远低于无慢性心瓣缺损的病例(75.6%)。 4.心炎見于49.9%的发作中,其临床表現有时颇不明显。仅在心电图檢查中发見者有41例,占所有經过心电图檢查的心炎病例的29%。由此可見心电图检查对診断心炎的独特价值。 5.在曾作心电图檢查的250次发作中有82次(32.8%)发見房窒傳导阻滞,其中68次为P-R间期延长。作...
