Quantitative histochemical methods were used for assaying several dehydrogenases in various cell zones of the rachitic rat epiphyseal cartilage during healing brought about by either vitamin D administration or fasting for 48 hr. 6-Phosphogluconic dehydrogenase activity was significantly greater in the cells of both the proliferating and hypertrophic zones of rachitic control rats as compared to those from vitamin D-treated or fasted rats. Activity of 6-phosphogluconic dehydrogenase in the cells from proliferating and hypertrophic zones was identical in the different groups. Lactic dehydrogenase activity of proliferating and hypertrophic cells obtained from rachitic controls was markedly higher than those from the fasted animals. Minor differences were noted in the malic and isocitric dehydrogenases and peptidase in the cartilage cells obtained from vitamin D-treated, untreated and fasted rats.

The activities of two enzymes involved in the oxidative part of the pentose cycle and one glycolytic enzyme have been measured by quantitative histochemical methods both in histologically pure nucleus supraopticus and in an adjacent area of the anterior hypothalamus of rat. In the nucleus supraopticus, glucose 6-phosphate dehydrogenase activity increased 34% and 6-phosphogluconate dehydrogenase activity declined by 9%, while lactic dehydrogenase activity did not change significantly after a thirsting period of 6 days. The nonsupraoptic, adjacent anterior hypothalamic area did not show significant changes in activity of any of the enzymes studied.

Cerebrospinal fluid lactic dehydrogenase activity was determined in 287 children. Among these, 87 had no central nervous system disease and were considered to be controls. Mean lactic dehydrogenase activity in 69 controls (excluding newborn infants) was 14 units. In 18 control infants less than 1 week of age, the mean lactic dehydrogenase activity was 50 units. Thirty-two patients with bacterial meningitis had a mean cerebrospinal fluid lactic dehydrogenase of 251 units on the initial examination; 20 patients with aseptic meningoencephalitis had a mean lactic dehydrogenase activity of 23 units. The difference between the lactic dehydrogenase activity in children with bacterial and aseptic meningitis was highly significant (p < 0.005). The clinical course of the patients studied was reflected by the change in cerebrospinal fluid lactic dehydrogenase activity on serial determinations. Spinal fluid isoenzyme patterns were studied in a few patients with bacterial and non-bacterial central nervous system disorders. This study indicates that the determination of lactic dehydrogenase in spinal fluid is a useful adjunct to other cerebrospinal fluid parameters in the differential diagnosis of central nervous system infections.
