Bleeding following tonsillectomy. A study of electrocoagulation and ligation techniques.

The efficiency of electrocoagulation (spot or zonal) and ligation for the control of bleeding was compared in 376 patients with tonsillectomy. Electrocoagulation and ligation was used in the same number of patients (188) in each group. A notable reduction in operative time (40%) was seen in cases in which spot or zonal electrocoagulation was employed. More morbidity was found in cases treated with zonal electrocoagulation. Both techniques were concluded to be equally effective in the control of bleeding following tonsillectomy.

Hostility in drug dependent individuals: its relation to specific drugs, and oral or intravenous use.

Although a number of studies have suggested that hostility and drug dependence may be related, there are few systematic studies of this issue. Using the Hostility and Direction of Hostility Questionnaire, the present study compares several drug-dependent groups of patients. Results showed that the intravenous in-patient group was more hostile on several variables than their out-patient counterparts, and also more hostile than an oral in-patient group. Barbiturate abusers were found to have high levels of hostility; amphetamine abusers were the least hostile group, and narcotic dependent patients were intermediate between the two. Correlations between scales of the HDHQ were all positive, and most were both high and statistically significant, suggesting that hostility represents a relatively generalized trait in drug-dependent subjects. The results are discussed both in terms of patient selection factors--the differential pressures on different types of patients, and in terms of direct drug effects. It is suggested that the hostility of drug-dependent patients may represent an important problem of personal functioning and may require special attention in treatment programmes.

Psychiatric aspects of narcolepsy.

Among twenty patients with narcolepsy intelligence was normal and no characteristic personality or psychopathology was found. A family history of psychiatric disorder was present in five and a past personal history in ten. Eight had a current psychiatric disorder and twelve either a current or past psychiatric disorder. Chronic sexual disorder was present in eleven. Arousal appeared to be the mechanism by which emotions precipitated symptoms. Ten patients were found to have had difficulties at work, in marriage or in social life.

Graded-hydrolysis studies on bael (Aegle marmelos) gum.

Graded hydrolysis of purified bael gum afforded three neutral and two acidic oligosaccharides, together with monosaccharides. These sugars were identified through periodate oxidation, methylation, reduction with lithium aluminum hydride, co-chromatography, and preparation of crystalline derivatives. The neutral oligosaccharides were characterized as 3-0-beta-D-galactopyranosyl-L-arabinose, 5-0-beta-D-galactopyranosyl-L-arabinose, and 3-0-beta-D-galactopyranosyl-D-galactose, and the acidic oligosaccharides as 3-0-(beta-D-galactopyranosyluronic acid)-D-galactose and 3-0-(beta-D-galactopyranosyluronic acid)-3-0-beta-D-galactopyranosyl-D-galactose.
