The inhibitory effects of the traditional herbal medicine Jindangwon (JDW) on streptozotocin (ST)-induced diabetic mellitus were studied using the ST-treated diabetic model. Glucokinase activity of pancreatic islets was severely impaired by ST treatment. However, when ST-treated islets were treated with 1 mg/ml of JDW, the enzyme activities of glucokinase and hexokinase were protected, glucose-6-phosphatase was not. When the effects of JDW on ST-induced ATP/ADP ratio of islets were assayed, JDW was effective in restoring of ATP/ADP ratio. In addition, ST decreased the enzyme activities of PDH, while JDW had a protective effect on the enzyme. ST-induced cGMP accumulation was significantly inhibited by JDW treatment. Furthermore, ST-induced nitrite formation was significantly inhibited by JDW treatment. JDW also showed the suppressed nitrite production in ST-treated pancreatic islet cells. When the islets (200/condition) were treated with ST (5 mM for 30 min), and then JDW was added to the ST-treated cells, 1.0 mg/ml of JDW showed the activated and recovered aconitase activity in pancreatic islet cells. When the effect of ST on the gene expression of pancreatic GLUT2 and glucokinase were examined, the level of GLUT2 and glucokinase mRNA in pancreatic islets was significantly decreased. However, JDW protected and improved the expression of protein and genes, indicating that JDW is effective on ST-induced inhibition of gene expression of GLUT2, glucokinase and proinsulin in islets. These results suggested that JDW is effective in this model to treat ST-induced diabetes.

Maruyama, Yoshiharu (Cornell University, Ithaca, N.Y.) and Martin Alexander. Localization of enzymes in the mycelium and microconidia of Fusarium oxysporum. J. Bacteriol. 84:307-312. 1962-Extracts prepared from mycelium and microconidia of Fusarium oxysporum f. cubense were fractionated into a soluble and four particulate fractions by differential centrifugation, and the distribution of several enzymes in the isolated cell constituents was examined. Succinic dehydrogenase, cytochrome oxidase, and a large amount of the reduced diphosphopyridine nucleotide (DPNH) cytochrome c reductase and reduced triphosphopyridine nucleotide cytochrome c reductase were associated with one of the particulate fractions prepared from the hyphae; fumarase and DPNH oxidase activities were largely found in the soluble and in a second particulate fraction. The highest recovery and concentration of diphosphopyridine nucleotidase was observed to be bound to a third type of hyphal granule. Aldolase, aconitase, glucose-6-phosphatase, and uricase were recovered entirely with the soluble mycelium constituents. Similar enzyme-distribution patterns were observed in microconidia. Several enzymatic activities of the mycelial extracts were compared with those in the extracts of microconidia.
