Effect of treatment with insulin or diet on intermediary metabolites in pregnant women with chemical diabetes in the third trimester of pregnancy.

The diurnal (07(30) - 16(00) profiles of glucose, 3-hydroxybutyrate (3-HB), non-esterified fatty acids (NEFA), and glycerol were studied in 19 pregnant women with gestational diabetes and eight pregnant non-diabetic controls. Nine of the gestational diabetic women were treated with intermediate and in some cases with fast acting insulin and diet and 10 were treated with diet alone. Although fasting plasma glucose levels were normal (less than 6.0 mmol/l) in 8 insulin-treated and 9 diet-treated gestational diabetics before the start of treatment, the profiles of glucose, NEFA and glycerol were generally higher in gestational diabetic compared to non-diabetic pregnant women. The insulin-treated group had lower, but not normal, plasma glucose and higher levels of glycerol than the women treated with diet only. The levels of 3-HB and NEFA were not significantly influenced by the type of therapy. It is suggested that treatment of gestational diabetes should consist of multiple injections of fast acting insulin.

Total body hyperthermia induced by a computerized microwave technique: studies in normal rats and in rats with liver tumors.

A computerized system for inducing total body hyperthermia by microwave irradiation was tested in rats. The tolerance to hyperthermia at different temperatures and fractions was studied as well as its effect on the growth of transplanted adenocarcinomas in the liver. Survival results indicated that 41.5 degrees C was maximum tolerated temperature both after single and repeated one hour exposures. Besides the high mortality with a greater temperature (42 degrees C) there was a significant rise in S-aspartate-amino-transferase (S-ASAT) and S-beta-hexosaminidase (beta-nagas) indicating damage of normal cells. No significant reduction of tumor volume could be registered after treatment with total body hyperthermia (41.5 degrees C) for one hour three times during a 24 hour period.

Cyclofenil in the treatment of scleroderma - a general view on the results after treating 29 cases.

Results are presented from an open treatment of 29 patients suffering from progressive systemic sclerosis (PSS) with cyclofenil, an oestrogenlike non-steroid compound with very low oestrogenicity, which was recently claimed to be effective in this disorder. The treatment resulted in significant improvement of the skin condition and regress of ulcerations, Raymaud's phenomenon, joint pain and stiffness. Most of the patients experienced an increased sense of well-being. A slight elevation of ASAT and ALAT was noted in seven patients and weight gain in two. Present data do not permit an assessment of whether the treatment might influence the visceral changes. A multi-centre controlled study is in progress.

Angiogenesis inhibitor TNP-470 augments the effect of repeated arterial ischemia on growth but does not affect take in a rat liver tumor model.

Transient hepatic arterial occlusion causes necrosis in solid hepatic tumors in the rat, but regrowth of tumor cells and capillaries takes place from the tumor periphery. It was therefore considered of interest to combine this treatment with the angiogenesis inhibitor TNP-470 (therapeutic model). Wistar rats with a dimethylhydrazine-induced adenocarcinoma implanted into the liver received one of the following treatments: TNP-470 + transient hepatic ischemia, transient hepatic ischemia alone, TNP-470 alone or sham solution alone. Rats were sacrificed one week after the start of treatment. In addition, we investigated if TNP-470 decreases the risk of tumor take in the liver after intraportal injection of viable tumor cells (adjuvant study). Transient hepatic ischemia combined with TNP-470 gave a smaller increase in tumor volume than transient hepatic ischemia (p < 0.01), TNP-470 (p < 0.001) alone or no treatment (p < 0.001). Transient hepatic ischemia or TNP-470 caused a significant suppression of tumor growth when compared to controls (p < 0.01 in both cases). In the adjuvant study, TNP-470 caused retardation of tumor growth (p < 0.01 as compared to controls) but did not affect tumor number. It is concluded that TNP-470 suppressed tumor growth, both alone and in combination with transient hepatic ischemia, but did not affect take of tumor.
