Principles of antimicrobial therapy.

It has been 2500 years since the Chinese began applying moldy soybean curd to cure skin infections. Technology today has refined the benefits of antibiotic-forming molds and bacteria and has greatly increased the number of antimicrobial drugs available to combat infection. Understanding the principles fundamental to rational therapy with these drugs will ensure the best of possible outcomes.

Effect of dexamethasone on gonadotrophin secretion in the gonadectomized sow and boar.

Saline solution or dexamethasone (DXM, 35 micrograms/kg bodyweight) was injected intramuscularly twice daily for four days into five ovariectomized sows and five castrated boars. Blood samples from an indwelling jugular vein catheter were taken at 15 min intervals for 12 h prior to DXM injection and on the fourth day of treatment in order to compare the effect on variables describing the pulsatile secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH). Dexamethasone treatment caused a decrease (p less than 0.05) in the number of pulsatile episodes of LH secretion in both gonadectomized boars and sows resulting in a significant decrease in mean concentrations. Follicle stimulating hormone secretion parameters appeared to be unaffected by DXM injection in both groups of animals. It is concluded that previously described differences in LH suppression in boars and sows given glucocorticoids may be attributed to the influence of gonadal hormones.

Pancreatic lesions in shock and their significance.

The pancreas was examined histologically in 146 cases of patients dying of shock. The finding of morphological evidence of disseminated intravascular coagulation (DIC) in the pancreas supports the opinion that the pancreas in highly sensitive to disturbances of blood perfusion. The presence of DIC combined with a variety of pathological lesions in the exocrine ad endocrine pancreas was sufficiently characteristic to justify use of the term " shock pancreatitis". The relative scarcity of data hitherto available on pathological changes in the pancreas caused by shock can be ascribed to changes in the management of shock. It is concluded that the pancreatic lesions described in this study could influence the outcome in shock treated by modern methods of resuscitation.

Potent reduction of basal acid output produced by meperidine.

Meperidine is a potent narcotic related chemically and pharmacologically to morphine and atropine. To examine its gastric antisecretory activity a study designed to test the effect of meperidine on basal acid secretion was carried out: 100 mg of meperidine given intramuscularly reduced basal acid output (BAO) by 66.3% at 1 hr (P less than 0.001), 64.9% at 2 hr (P less than 0.001), and 44.9% at 3 hr (P = 0.005). This degree of reduction of BAO by this dose of meperidine did not differ from that produced by 30 mg of propantheline intramuscularly. These results demonstrate that meperidine in standard classical doses is a potent inhibitor of BAO in man.
