E-10-hydroxynortriptyline, a metabolite of nortriptyline with half the norepinephrine re-uptake blocking potency of the parent drug, but only 5% of its anticholinergic effect, was as effective as cocaine in demonstrating ocular sympathetic paresis. In five rabbits with unilateral superior cervical ganglionectomies, bilateral 5% cocaine HCl or E-10-hydroxynortriptyline maleate eye drops increased (P less than 0.001) the mean +/- SE anisocoria at 1 h by 1.84 +/- 0.03 mm or 2.16 +/- 0.33 mm, respectively. A single drop of E-10-hydroxynortriptyline did not alter corneal thickness or endothelial cell count.

We report a 86-year-old woman who developed dementia, gait disturbance, speech disturbance, and right hemiparesis. The patient was well until March of 1979 when upon wakening up on one morning she noted slurring of her speech and weakness in her left upper and lower extremities. These symptoms cleared up during the next several months, however, she noted weakness in her left leg again in May 1985. In 1988, her posture became stooped and she walked in small steps. In 1990, she developed memory disturbance and difficulty in naming. In March 1993, she developed weakness in her right hand; she was treated with aspirin and amantadine HCl, however, she deteriorated during the next two week period, and was admitted to our hospital on March 27, 1993. On admission, she appeared alert, however, she could not answer verbally to questions; she could only utter unintelligible sounds. Apparently she was markedly demented. Her blood pressure was 170/98 mmHg, and general physical examination was unremarkable. Cranial nerves were grossly normal except for marked non-fluency in her word expression. She could not stand or walk, and apparently her right upper and lower extremities were paralyzed with some contracture. Deep reflexes were normally active without asymmetry. Chaddock sign was positive bilaterally. Sensory examination was difficult. Pertinent laboratory examination included WBC 13,000/microliters, BUN 152mg/dl, creatinine 3.75mg/dl, CRP 20.1mg/dl; a chest X-ray film revealed pneumonic shadow in the upper and the middle right lung fields. Cranial CT scan revealed multiple lacunar infarctions in both basal ganglia and cerebral white matters; periventricular lucency was also noted. She was treated with antibiotics and intravenous fluid. Acid-fast bacilli were recovered from sputum, and she was transferred to another hospital for the treatment of pulmonary tuberculosis. After its treatment she returned to our hospital on July 8, 1993, when her condition was complicated with aspiration pneumonia. On admission, she was semicomatose, and no intelligible words were heard. Right facial paresis of the central type was noted. She was unable to stand or walk, and her right upper and lower extremities were paretic. Deep reflexes were increased with extensor toe sign on the right. She was treated with chemotherapy and intravenous fluid, however, her clinical course was complicated with respiratory as well as urinary tract infections. She developed cardiac as well as renal failure and expired on September 25, 1993.(ABSTRACT TRUNCATED AT 400 WORDS)

Fomocaine (CAS 56583-43-8) is a local anaesthetic (LA) with long lasting surface effect and low toxicity. Nevertheless, it is not optimal yet. Therefore, 7 newly synthesised derivatives, 4 diethanolamines (OE 6000, OE 7000, OE 8000, OE 9000) and 3 morpholines (OE 500, OE 1000, OE 5000) were compared with procaine-HCl (CAS 51-05-8) and tetracaine-HCl (CAS 136-47-0) in rats. Based on standard methods for the testing of LA effects and using two methods for characterising side effects and toxicity of LA (paresis of the N. ischiadicus, LD50) it can be concluded that: a) The very good surface anaesthesia caused by especially fomocaine and tetracaine could be stated but concerning conduction anaesthesia procaine is better qualified. b) Concerning conduction anaesthesia, diethanolamine derivatives are more potent compared to morpholine derivatives. c) Surface anaesthesia shows a different picture: the effect of fomocaine is in between. d) The paresis of the N. ischiadicus as a first sign of toxic side effects indicated that low effect is combined with short paresis. e) Compared to the LD50 of fomocaine, the toxicity of OE 500 and OE 5000 is only one half. On the basis of the experiments with fomocaine derivatives, distinct structure-activity relationships could be demonstrated for fomocaine derivatives concerning a) LA effects and b) toxicity. Altogether OE 9000 could be a promising candidate for systemic use.
