Diabetic treatment and primary ventricular fibrillation in acute myocardial infarction.

The relation between mode of therapy and mortality rate and incidence of primary ventricular fibrillation was studied in 265 patients with diabetes mellitus and acute myocardial infarction. Sixty patients were being treated with diet only, 54 were receiving insulin and 151 were taking oral hypoglycemic agents. Fourteen patients (5.3 percent) had primary ventricular fibrillation, and all but one died. No statistically significant association was found between the incidence of primary ventricular fibrillation and the type of treatment for diabetes mellitus. Sixty-four (24.2 percent) of the 265 patients died during hospitalization. Mortality was greater among diabetic patients receiving oral therapy. However, after adjusting for age and sex, the difference among these three treatment regimens did not reach the P less than 0.05 level of significance.

Transient neonatal hyperparathyroidism associated with maternal hypoparathyroidism.

The newborn infant of a mother with hypoparathyroidism following thyroidectomy showed transient hypercalcemia and hypermagnesemia. Hypophosphatemia, as found in adult hyperparathyroidism, was not noted in this case, or in three of five other reported cases of neonatal hyperparathyroidism secondary to maternal hypoparathyroidism.

[A model of "panic" in wild mice (Mus musculus L.)].

Wild mice were submitted in groups of 5, 10 or 20 individuals to more and more pressing and dreadful experimental situations. The smallest groups were the most disturbed, during the longest time; in the groups of 20, a great number of mice clustered closely and they did not attempt to try and fly; in the groups of 10, the mice were very busy exploring all around the walls of the open-field. But, when the mice were in front of a hiding place without the ability of running inside, the alarm gave rise to a general paroxystic disturbance. The behaviour of the wild Mice and that of Man seems very similar when the shock is particularly violent.

Prostatic fluid lactic dehydrogenase isoenzyme patterns of prostatic cancer and hyperplasia.

LDH isoenzyme patterns were determined in prostatic fluid from 286 patients with a prostate gland judged to be normal, the site of benign hyperplasia on clinical evidence or the site of benign hyperplasia or carcinoma on the basis of histologic evidence. Fluid from 12 of 15 patients (80 per cent) with carcinoma representing all stages and grades of disease showed an LDH-V/I ratio of more than 3. This ratio was exceeded in only 6 of 57 (11.8 per cent) and 14 of 97 (14.4 per cent) patients in whom the diagnosis of benign prostatic hyperplasia without evidence of infection was established histologically or clinically, respectively. An LDH-V/I ratio exceeding 3 was seen commonly in patients with a diagnosis of benign prostatic hyperplasia with a recent history suggesting infection and more than 10 WBCs per high power field on microscopic examination of the prostatic fluid. These observations suggest that an LDH-V/I ratio exceeding 3 in the prostatic fluid in the absence of a history of infection and more than 10 WBCs per high power field on microscopic examination should be regarded as an indication of a high risk of the presence or development of a malignancy of the prostate. The results obtained also support the concept that, in the presence of malignancy, expressed prostatic fluid provides an adequate sample of cells with altered metabolism.

Effects of immunization with LDH-X on fertility.

Immunological regulation of fertility can be best achieved if a defined macromolecule is used to provide the antigenic stimulus. Proteins with known enzymatic properties are attractive molecules in this area if it can be demonstrated unequivocally that they are unique constituents of spermatozoa, and are completely foreign to the female. This paper describes immunosuppression of fertility by the sperm-specific isozyme of lactate dehydrogenase (LDH-X). In addition, evidence is reviewed which suggests that acrosomal proteinase and hyaluronidase may be unique to sperm. Data are presented which confirm the sperm specificity of LDH-X and the immunochemical homogeneity of purified preparations of this isozyme. Immunization of female rabbits with LDH-X significantly reduces the fertility of these animals. Experimental results indicate that the primary effect of immunization involves blockage of fertilization. While those ova which are fertilized in an immune environment develop and implant normally, there is a high rate of post-implantation embryo mortality. Rabbit blastocysts transferred to immune recipients implant at the same rate as in non-immune controls. These findings are consistent with the conclusion that the developing embryo must interact with antibody during the pre-implantation stages of pregnancy when antigenic sites conferred by the sperm LDH-X are available. Such interaction can be demonstrated directly by immunofluorescence techniques.
