Tenidap, a novel compound inhibiting cyclooxygenase and lipoxygenase, also possessing an inhibitory effect on interleukin-1 secretion by in vitro activated macrophages, has been administered to the non obese diabetic (NOD) mouse to evaluate its action on the induction and progression of insulitis and the diabetes incidence. Animals were allocated to three groups (group A: control group; group B: 12 mg/kg/day Tenidap; group C: 36 mg/kg/day Tenidap); female animals only were followed up to investigate the effect on diabetes incidence. The administration of Tenidap influenced the natural course of insulitis in male NOD mice; thus, at 60 and 100 days of age the mean percentage of infiltrated islets was significantly reduced compared to control animals (p less than 0.02). Moreover the severity of lymphocytic infiltration at 60 days of age was reduced in male mice of group B and C compared to control mice (p less than 0.004 and p less than 0.0001, respectively) whereas at 100 days of age this difference was not significant. However the progression towards severe insulitis in male animals receiving Tenidap was halted compared to control animals. Tenidap had also a significant dose dependent effect at 60 days on the severity of lymphocytic infiltration (group B vs. group C, p less than 0.01). By contrast, this agent had no effect on the degree of insulitis and diabetes incidence in female NOD mice. In both sexes at the end of follow-up a significant reduction in body weight was observed in animals of Group C compared to control animals (p less than 0.002).(ABSTRACT TRUNCATED AT 250 WORDS)

UI MeSH Term Description Entries
D007211 Indoles Benzopyrroles with the nitrogen at the number one carbon adjacent to the benzyl portion, in contrast to ISOINDOLES which have the nitrogen away from the six-membered ring.
D007515 Islets of Langerhans Irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the PANCREAS among the exocrine acini. Each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. There are four major cell types. The most abundant beta cells (50-80%) secrete INSULIN. Alpha cells (5-20%) secrete GLUCAGON. PP cells (10-35%) secrete PANCREATIC POLYPEPTIDE. Delta cells (~5%) secrete SOMATOSTATIN.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008297 Male Males
D003922 Diabetes Mellitus, Type 1 A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
