Effect of tweens on the production of ergot alkaloids by Aspergillus fumigatus.

Tween 80, which caused increased biomass formation, also produced the highest increase in the uptake rate of all components of the medium. The fatty acid components of the respective Tweens, i.e. palmitic acid (Tween 40), stearic acid (Tween 60), and oleic acid (Tween 80), have no effect either on alkaloid production or on substrate uptake. The fatty acid composition was different in the cell membrane of the culture supplemented with Tween 60 and facilitated the transport of metabolites into the cells.

Ocular changes in epidermolysis bullosa letalis.

Ocular changes in a rare case of epidermolysis bullosa letalis included edema of the trabecular meshwork, ciliary body, lens, optic nerve, and formation of edema cysts in the iris. The retinal was completely detached and focally necrotic. Foci of necrosis and detachment of the retinal pigment epithelium were also observed with occasional breach in the Bruch's membrane. The choroid showed focal edema and congestion.

Postanesthetic necrotic defect.

An unusual defect was noted in a 10-year-old girl near the usual site of administration for an inferior nerve block. It was interpreted to be the result of a local anesthetic having been administered 2 months previously.

Silent anomalies of the urinary tract and congenital heart disease.

Postangiocardiographic screening of infants and children with congenital heart disease for silent anomalies of the urinary tract yielded an incidence of 7.7 percent in 260 so studied. The incidence was 29 percent in 21 babies who came to autopsy and had been studied at catheterization but without this screening. Patients with atrial septal defect had the highest incidence of urinary tract anomalies, while those with ventricular septal defect and tetralogy had an average incidence. Some of the lesions discovered were potentially significant even though silent. They were found with sufficient frequency to warrant routine use of this screening technique at cardiac catheterization.

Malignant mediastinal chemodectoma.

A 20-year-old man with a posterior mediastinal mass and erosion of the rib proved to have a malignant chemodectoma. The case is of interest because of the rare location and malignant fatal course.

Effects of ultrasonic nebulization on pulmonary mechanics and blood gases in obstructive pulmonary disease.

Administration of ultrasonically nebulized mist to 17 patients with obstructive lung disease resulted in a temporary deterioration of mechanical lung function with decreases in vital capacity (VC), forced expired volume in one second expressed as a percentage of VC (FEV(1)%), and compliance and with increased inspiratory and expiratory airway resistance. Despite hyperventilation there was an associated decrease in arterial oxygen tension. Although concomitant administration of a bronchodilator afforded protection against the bronchospastic reaction, blood gas derangements were still provoked.

Action of L- -methyldopa-hydrazine on the blood pressure of patients receiving levodopa.

The blood pressure and pulse rate have been compared in a 'double blind, cross over' study involving twenty patients with idiopathic Parkinsonism receiving maximum tolerated dosage of levodopa with and without an extracerebral decarboxylase inhibitor, L-alpha-methyldopahydrazine. The supine and erect systolic pressures were significantly higher and the erect pulse rate significantly lower during administration of L-alpha-methyldopahydrazine. The implications of these observations are discussed.

Assessment of cyclobenzaprine in the treatment of spasticity.

The efficacy of cyclobenzaprine 60 mg/day in the treatment of spasticity was assessed in a double-blind crossover trial of two weeks' duration in 15 patients suffering from cerebral or spinal spasticity. Independent clinical and electromyographic methods were used. The effects of cyclobenzaprine did not differ significantly from those of placebo. The administration of a higher dosage, 150 mg/day, to one patient revealed a dose-related response, but the degree of improvement was clinically small. Apart from a skin rash there were no significant untoward effects of therapy.
