ABSTRACT
Changes in level of isoenzyme LDH1 seem to be a valuable criterion in differentiating acute myocardial infarction from active coronary insufficiency without infarction. LDH1 level increases noticeably within 48 hours after onset of pain from acute myocardial infarction but tends to decrease if the pain is due to active coronary insufficiency.

Serum magnesium was measured in 89 control subjects ages 19 to 86 years and in 64 patients (ages 35 to 82 years) who had suffered from acute myocardial infarction at least 6 months previously. No differences were found in the serum magnesium levels due to age or sex nor was there any statistical difference between the mean levels in the two groups. It is concluded that the level of serum magnesium is not associated with the presence or absence of clinically evident ischemic heart disease.

Bacteriological cultures of material collected on the cervix uteri and endometrium of 75 controls, 150 women using an intrauterine contraceptive device and 20 women who had undergone abdominal hysterectomy, have been studied by the authors. Positive cultures were found in all three groups of women. The difference in percentage of positive cultures in users and non-users of intrauterine contraceptive devices was not significant and this has lead the authors to conclude that the intrauterine contraceptive device does not alter endometrial flora, unless it is left in situ for a period exceeding two years and during the first two weeks of the cycle. In this study, the cultures made on the material collected on hysterectomy specimens of patients that had never used intrauterine contraceptive devices yielded the lowest percentage of positive cultures.
