Triglyceride composition of Sapindus mukorossi seed oil.

The fatty acid composition of Sapindus mukorossi seed oil was determined by spectrophotometry, urea complexation, and gas liquid chromatography (GLC). The percentages of individual acids were found to be: palmitic, 4.0; stearic, 0.2; arachidic, 4.4; oleic 62.8; linoleic, 4.6; linolenic, 1.6; and eicosenoic, 22.4. Triglyceride composition was calculated from the fatty acid compositions of the native oil and of the monoglycerides produced from it by pancreatic lipase hydrolysis. The oil is composed of 0.1, 2.1, 22.0, and 75.8% trisaturated, monounsaturated disaturatd, diunsaturated monosaturated, and triunsaturated glycerides, respectively. The special characteristic of the Sapindus mukorossi seed oil is its content of 26.3 and 26.7% triolein and eicoseno-di-oleins, respectively.

Toxicological investigations of cases of death involving codeine and dihydrocodeine.

Drug levels in post-mortem specimens from 6 cases of poisoning involving codeine or dihydrocodeine have been determined using a direct extraction method followed by gas liquid chromatography. The relevant case histories are described. A preliminary qualitative investigation of dihydrocodeine metabolism has been described involving the analysis of urine samples by thin layer and gas chromatography.

Status of minor depression or dysthymia in primary care following a randomized controlled treatment.

This report describes the rates of recovery and remission from minor depression or dysthymia in primary care patients three months after completing a randomized controlled treatment trial. The subjects were primary care patients who received > or =4 treatment sessions with Problem-Solving Treatment, paroxetine, or placebo and who completed an independent assessment 3 months after the study (201 with minor depression, 229 with dysthymia). The 17-item Hamilton Rating Scale for Depression (HAMD), semistructured questions about postintervention depression treatments, and baseline medical comorbidity, neuroticism, and social function were the primary measures. For minor depression 76% and for dysthymia 68% of subjects who were in remission at the end of the 11-week treatment trial were recovered (HAMD < or =6) three months after the treatment trial. Of patients who were not in remission at 11 weeks, for minor depression 37% and for dysthymia 31% went on to achieve remission at 25 weeks. The majority of patients chose not to use antidepressants or psychotherapy after the trial. Patients with minor depression that had greater baseline social function and lower neuroticism scores were more likely to be recovered. For patients with minor depression, these findings suggest a need for some matching of continuation and maintenance treatment to patient characteristics rather than uniform, automatic treatment recommendations. Because of the chronic, relapsing nature of dysthymia, practical improvements in encouraging effective continuation and maintenance phases of treatment are indicated.

Experience with balloon valvuloplasty in pulmonary stenosis.

Fourteen patients of pure valvular pulmonary stenosis of moderate to severe degree underwent balloon valvuloplasty in the Department of Cardiology, SSKM Hospital, Calcutta. Haemodynamic study revealed that immediately after valvuloplasty, right ventricular pressure dropped down from 125 +/- 17.18 mmHg. to 56.67 +/- 8.72 mmHg. (mean +/- SD). Restudy was done in each case after 4 weeks, which showed that right ventricular systolic pressure had further dropped down to 46.71 +/- 5.06 mmHg. (Mean +/- SD). Patients were further followed up for 6 to 15 months (mean 10 months). During the follow-up period, all the patients remained asymptomatic. Drop of right ventricular systolic pressure was maintained except in one case in which the peak systolic pressure gradient across the pulmonary valve was raised to 61 mmHg. from 24 mmHg., the gradient achieved immediately after valvuloplasty.
