Radiopharmaceuticals for radionuclidic diagnostics of bone pathology (review)

This review gives a brief outline of the history of development of radiopharmaceuticals (RPh) for radionuclide diagnostics of bone pathology. The advantages of RPh based on ^99mTc-diphosphonates are demonstrated.

Visualization of patent foramen ovale by biplanar transesophageal echocardiography

Summary It is difficult for conventional transthoracic echocardiography (TTE), by which precise and accurate images of interatrial septum (IAS) can not be acquired, to diagnose patent foramen ovale (PFO) clearly. To evaluate the diagnostic value of biplanar transesophageal echocardiography (TEE) for PFO, TTE and biplanar TEE were performed simultaneously in 270 patients. It was found that in 7 patients patent foramen ovale was detected only through longitudinal planes of biplanar TEE. IAS, which consists of primitive septum and membrane of fossa ovalis, can be directly visualized by two-dimensional images of TEE; in patients with PFO, a dull color flow, which shunts from the right atria to the left atria through the gap between primitive septum and fossa ovalis, can be detected by color Doppler flow images. Furthermore, some right-to-left shunting microbubbles through the valve of patent fossa ovalis can be discovered by cardiac acoustic contrast echocardiography. In conclusion, biplanar TEE combined with color Doppler image and cardiac acoustic contrast facilitates a definite diagnosis of patent foramen ovale as the excellent anatomic images of IAS can be obtained from multiple views under this kind of performance.     

Pharmacokinetics of Controlled Release and Immediate Release Morphine Sulphate Tablets after a Single Dose and Multiple Doses in Chinese Volunteers

健康志愿者１０名，随机交叉口服硫酸吗啡控释片（ＣＲＭＳ）３０ｍｇ（３０ｍｇ×１）和硫酸吗啡普通片（ＩＲＭＳ）２０ｍｇ（１０ｍｇ×２），分别于服药前后各时点取静脉血，用ＧＣＭＳ测定血浆中吗啡含量。以药代软件程序处理，分别求得ＣＲＭＳ和ＩＲＭＳ的Ｃｍａｘ为１９．３８±３．８０和２１．２７±６．２１ｎｇ／ｍｌ；ｔｍａｘ为２．３６±０．３７ｈ和０．５５±０．１６ｈ；ｔ１／２β为３．５３±０．８７ｈ和３．０３±０．７４ｈ，曲线下面积ＡＵＣ为１４５．１５±１７．６５和９３．０８±１６．６５ｎｇ·ｈ／ｍｌ。癌症病人多次口服硫酸吗啡至稳态，ＣＲＭＳ和ＩＲＭＳ的峰浓度分别为２７．４３±０．３３ｎｇ／ｍｌ，２２．６８±０．１６ｎｇ／ｍｌ；谷浓度分别为１９．４５±１．４４ｎｇ／ｍｌ；１８．１４±０．４９ｎｇ／ｍｌ。     

Effects of Diazepam,Phenobarbital,Propranolol,and Cimetidine on Diazepam Oxidizing Isoenzymes in Rat Liver Microsomes

研究地西泮、苯巴比妥、普萘洛尔和西咪替丁对地西泮氧化代谢的影响及其药酶蛋白的初步分析，应用ＨＰＬＣ，ＳＤＳ聚丙烯酰胺凝胶电泳和薄层扫描测定地西泮及其代谢物，并对大鼠肝微粒体和酶蛋白进行分离和含量测定。结果表明地西泮、普萘洛尔和西咪替丁使肝微粒体中Ｐ４５０含量明显降低。地西泮和普萘洛尔明显抑制地西泮Ｃ３羟化活性，大剂量普萘洛尔尚能抑制地西泮Ｎ脱甲基。苯巴比妥明显诱导Ｐ４５０生成，增强地西泮Ｎ脱甲基和Ｃ３羟化酶活性及分子量为５１，０００和５９，０００的电泳蛋白带，而地西泮、普萘洛尔则呈抑制作用。并发现，地西泮Ｎ脱甲基酶活性和分子量为５９，０００蛋白含量呈线性相关（Ｐ＜０．０５），而Ｃ３羟化酶活性则与５１，０００蛋白含量呈线性相关（Ｐ＜０．０１）。因此地西泮Ｃ３羟化代谢可能与５１，０００的Ｐ４５０酶蛋白有关，而Ｎ脱甲基代谢则可能与５９，０００的Ｐ４５０酶蛋白有关。     

Intestinal parasitic infestation in pediatric gastroenterology outpatient clinic Dr. Pirngadi Hospital Medan

A retrospective study had been done at the outpatient clinic sub division of Pediatric Gastroenterology, Dr. Pirngcdi Hospital Medan, comprising patients from 1 January 1985-31 December 1987. There were 874 patients. Three hundred seventy eight (43.25%) patients consisting of 210 (55.56%) males and 168 (44.44%) females had intestinal parasitic infestations. The youngest patient was 5 months and the oldest was 14 years and 3 months. Ascaris lumbricoides was found in 215 patients (24.60%) while Trichuris trichiura, hookworm, Oxyuris vermicularis, Hymenolepis nana, and Taenia were in 152 (17.39%), 13 (1.49%), 4 (0.46%), 15 (1.72%) and 4 (0.46%) cases respectively. Entamoeba histolytica was found in 121 (13.84%) and Giardia lamblia in 16 (1.83%) patients. The highest age specific attack rate was found in the age group of 5-10 years (65.67%). Ascaris lumbricoides was most frequently found namely in 100 children (26.46%), followed by Entameba histolytica in 73 (19.31%) and mixed infestation of Ascaris lumbricoides and Trichuris trichiura in 68 (17.99%) patients. One hundred seventy three (66.28%) under five patients with intestinal parasitic infestation had malnutrition while of the 433 under fives without intestinal parasitic infestation only 201 (46.42%) suffered from malnutrition (P less than 0.001).
