Interpeduncular fossa sign: CT criterion of subarachnoid hemorrhage

A retrospective study of 100 cerebral computed tomography scans interpreted as displaying subarachnoid hemorrhage was undertaken to determine the frequency of blood in the interpeduncular fossa as a useful radiographic sign. The results indicate that the interpeduncular fossa sign is second only to blood in the Sylvian fissure-circular sulcus area as a reliable indicator of subarachnoid hemorrhage on CT scans.     

MR imaging of the scrotum: normal anatomy

High-resolution magnetic resonance (MR) imaging with a surface coil was utilized to evaluate the normal scrotum. Scrotal contents, spermatic canal, and inguinal regions were visualized within the same field of view. Differences in signal intensity in the testis, epididymis, tunica albuginea, fluid, fat, and spermatic cord allowed for clear delineation of these structures in detail. The high contrast and spatial resolution of MR imaging, coupled with the wide field of view and absence of ionizing radiation, make MR imaging well suited for evaluation of the scrotum.     

Synthesis of 3H, 14C and 2H4 labelled SCH 211803

[³H]SCH 211803, at a specific activity of 1.56 Ci/mmol, was prepared by direct exchange with tritiated water and platinum metal. [²H₄]SCH 211803 was prepared from [²H]formaldehyde in a seven step synthesis in 10% yield. [¹⁴C]SCH 211803 was prepared from N‐benzyl‐4‐hydroxy[2‐¹⁴C]piperidine in a four‐step synthesis in 35% radiochemical yield. Additionally a high specific activity batch of [³H]SCH 211803 was prepared by Ru(Ph₃P)₃Cl₂ catalysed exchange with 90 at% tritiated water to a specific activity of 35 Ci/mmol.

Psychotropic properties of nootropic substances with a cholinergic action component in single and long-term use

Long-term administration of centrophenoxine and cleregil was found to exert on rats the antiamnestic and anxiogenic-like effects, to increase emotional reactivity and aggressiveness, to reduce motor activity and readiness to contact. The withdrawal of centrophenoxine and especially cleregil was followed by still greater enhancement of emotional reactivity and the appearance of spontaneous aggressiveness.     

N-(6,6-二甲基-2-庚烯-4-炔基)-N-甲基-α-取代-1-(4-取代)萘甲胺类的合成及抗真菌活性

根据氮唑类和烯丙胺类抗真菌化合物的构效关系、作用机理。设计合成了30个N-(6,6-二甲基-2-庚烯-4-炔基)-N-甲基-α-取代-1-(4-取代)萘甲胺类化合物。初步体外抑菌试验结果表明,大多数目标化合物对八种试验菌株都有不同程度的抗真菌活性。化合物Ⅰ_1a的真菌活性大致与克霉唑相当,对白念珠菌的活性明显高于naftifine和terbinafine,但对其它七种菌株的活性均不及naftifine和terbinafine;化合物Ⅲ_1a对八种试验菌株的活性均与terbinafine相当。     

Causes of jaundice during hepatic artery infusion chemotherapy

Jaundice develops in many patients with liver metastases from colorectal adenocarcinoma during hepatic arterial infusion chemotherapy (HAIC). The usual cause is thought to be hepatotoxicity from the chemotherapeutic agent or biliary obstruction from progressive neoplastic disease. The authors evaluated the abdominal computed tomography and ultrasound examinations performed on 49 patients who were jaundiced during long-term HAIC. In only one patient was diffuse intrahepatic biliary dilatation caused by an obstructing mass in the porta. Two patients had metastatic hepatic lesions causing focal biliary obstruction. Intrahepatic dilatation without an obstructing mass occurred in 20 patients. Percutaneous or endoscopic cholangiograms were commonly interpreted prospectively as showing extrinsic compression by metastases, but no mass was confirmed on imaging studies. Seven patients had focal intrahepatic ductal dilatation from stricture without an associated mass. The remaining 19 patients had normal-caliber ducts; their jaundice was caused by chemical hepatitis. This series suggests that the most common causes of jaundice in these patients are chemical hepatitis and common bile duct stricture, complications of intraarterial chemotherapy, rather than neoplastic obstruction. Stricture formation may be confused with extrinsic compression on direct cholangiograms.     

Clinical characteristics of the outbreak of Salmonella infection caused by Salmonella enteritidis

The data are presented on an outbreak of salmonellosis induced by S. enteritidis. Gastrointestinal symptoms were recorded in 97.8% of 90 patients, 2.2% of them developed a generalized form. The disease ran a moderate course in 84.5% and a severe course in 2.2% of the patients majority of whom suffered from intoxication and dehydration. The therapeutic response was achieved upon rehydration treatment with crystalloid solutions.
